     BACKGROUND 
     1. Field

     2. Description of Related Art 
     A liquid crystal display (LCD) device displays an image by forming an electric field (i.e., an electric potential difference) between a pixel electrode and a common electrode of a liquid crystal capacitor included in each pixel. In the liquid crystal capacitor, a liquid crystal layer is placed between the pixel electrode and the common electrode so that light transmittance of the liquid crystal layer is controlled by an intensity of the electric field formed between the pixel electrode and the common electrode. Recently, an LCD device having a thin film transistor (TFT) as a switching element included in each pixel has been in widespread use. This type of LCD device has been referred to as a TFT LCD device. 
     An LCD device may periodically invert polarities of data signals to reduce or prevent deterioration of the liquid crystal capacitor included in each pixel due to polarization. For example, the LCD device may employ inversion methods such as a dot inversion method, a line inversion method, a column inversion method, a frame inversion method, a Z-inversion method, an active level shift (ALS) inversion method, etc. However, these inversion methods may cause various problems, such as horizontal crosstalk, vertical crosstalk, unnecessary power consumption, etc.

     DETAILED DESCRIPTION 
     The example embodiments are described more fully hereinafter with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity. 
     It will be understood that when an element or layer is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it can be directly on, directly connected, or directly coupled to the other element or layer, or intervening elements or layers may also be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like or similar reference numerals refer to like or similar elements throughout. As used herein, the term “and/or” includes any combination of one or more of the associated listed items. 
     It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, patterns, and/or sections, these elements, components, regions, layers, patterns, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, pattern, or section from another element, component, region, layer, pattern, or section. Thus, a first element, component, region, layer, pattern, or section discussed below could be termed a second element, component, region, layer, pattern, or section without departing from the teachings of example embodiments. 
     Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     The terminology used herein is for describing particular example embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     Example embodiments are described herein with reference to cross sectional illustrations that are schematic illustrations of illustratively idealized example embodiments (and intermediate structures) of the present invention. As such, variations from the shapes of the illustrations because of, for example, manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include variations in shapes that result, for example, from manufacturing. The regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the present invention. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
       FIG. 1  is a diagram illustrating a liquid crystal display (LCD) panel  100  in accordance with example embodiments. 
     Referring to  FIG. 1 , the LCD panel  100  includes a plurality of pixels  110 , a first sub gate-line  120 _ 1 , a second sub gate-line  120 _ 2 , a plurality of gate-lines  130 _ 1  through  130 _k, a plurality of odd data-lines  140 _ 1  through  140 _ 5 , and a plurality of even data-lines  150 _ 1  through  150 _ 5 . The first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , and the plurality of gate-lines  130 _ 1  through  130 _k are collectively referred to as row-lines. In some example embodiments, the LCD panel  100  further includes a charge-sharing control circuit  160 . In the embodiment of  FIG. 1 , for ease of illustration, five odd data lines  140 _ 1  through  140 _ 5  and five even data lines  150 _ 1  through  150 _ 5  are shown and described. However, the LCD panel  100  may contain another number of data lines without departing from the spirit or scope of the present invention. 
     An LCD device displays an image by forming an electric field (i.e., an electric potential difference) between a pixel electrode and a common electrode of a liquid crystal capacitor included in each pixel. In the liquid crystal capacitor, a liquid crystal layer is placed between the pixel electrode and the common electrode so that light transmittance of the liquid crystal layer is controlled by an intensity of the electric field formed between the pixel electrode and the common electrode. 
     Here, if the electric field is formed between the pixel electrode and the common electrode in one direction for a long time, the liquid crystal capacitor may deteriorate due to polarization. Hence, the LCD device may periodically invert polarities of data signals to reduce or prevent the deterioration of the liquid crystal capacitor included in each pixel. For example, the LCD device may employ inversion methods such as a dot inversion method, a line inversion method, a column inversion method, a frame inversion method, a Z-inversion method, an active level shift (ALS) inversion method, etc. 
     The dot inversion method inverts polarities of data signals with respect to alternating dots. Namely, a certain pixel receives a data signal having a polarity opposite to data signals received by its adjacent pixels in both a vertical direction (i.e., a column direction) and a horizontal direction (i.e., a row direction). The line inversion method inverts polarities of data signals with respect to alternating gate-lines (for example, rows). The column inversion method inverts polarities of data signals with respect to alternating data-lines (for example, columns). The frame inversion method inverts polarities of data signals with respect to alternating frames (for example, odd frames and even frames). 
     The Z-inversion method arranges a plurality of pixels in zigzags of a column direction. Thus, the Z-inversion method substantially performs the dot inversion when data signals are applied to the pixels in a similar way to the column inversion method. The ALS inversion method substantially inverts polarities of data signals in a similar way to the line inversion method. Here, the ALS inversion method may reduce a voltage displacement applied to a common electrode compared to the line inversion method. 
     However, these inversion methods may result in various problems. For example, the dot inversion method may reduce or prevent vertical crosstalk and/or horizontal crosstalk because a certain pixel receives a data signal having a polarity opposite to data signals received by its adjacent pixels in a vertical direction (i.e., a column direction) and a horizontal direction (i.e., a row direction). However, the dot inversion method may consume high power because a pulse repetition frequency of data signals (i.e., variance of data signals) is relatively high as the dot inversion method inverts polarities of data signals with respect to alternating dots. 
     In comparison, the line inversion method may reduce power consumption compared to the dot inversion method because a pulse repetition frequency of data signals (i.e., variance of data signals) is decreased. However, the line inversion method may cause horizontal crosstalk because the line inversion method inverts polarities of data signals with respect to alternating gate-lines. The column inversion method may also reduce power consumption compared to the dot inversion method because a pulse repetition frequency of data signals (i.e., variance of data signals) is decreased. However, the column inversion method may cause vertical crosstalk because the column inversion method inverts polarities of data signals with respect to alternating data-lines. 
     As for the other inversion methods mentioned above, the frame inversion method may cause flickers when frames are changed because the frame inversion method inverts polarities of data signals with respect to alternating frames. By contrast, the Z-inversion method may reduce power consumption compared to the dot inversion method because the Z-inversion method applies data signals to the pixels in a similar way to the column inversion method. However, the Z-inversion method may cause vertical stripes in case that data signals have specific patterns. Finally, the ALS inversion method may reduce power consumption compared to the line inversion method because a voltage displacement applied to a common electrode is small compared to the line inversion method. However, the ALS inversion method may cause horizontal crosstalk because the ALS inversion method inverts polarities of data signals with respect to alternating gate-lines. 
     For overcoming various problems of these inversion methods, the LCD panel  100  includes the pixels  110 , the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , the gate-lines  130 _ 1  through  130 _k, the odd data-lines  140 _ 1  through  140 _ 5 , and the even data-lines  150 _ 1  through  150 _ 5 . The pixels  110  are arranged in a matrix manner (that is, in rows and columns) at portions corresponding to crossing regions of the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , the gate-lines  130 _ 1  through  130 _k, the odd data-lines  140 _ 1  through  140 _ 5 , and the even data-lines  150 _ 1  through  150 _ 5 . 
     Here, each of the pixels  110  is coupled to the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , or one of the gate-lines  130 _ 1  through  130 _k via a gate terminal of its switching element (e.g., a TFT). Additionally, each of the pixels  110  is coupled to one of the odd data-lines  140 _ 1  through  140 _ 5  or one of the even data-lines  150 _ 1  through  150 _ 5  via a source terminal of its switching element. As a result, each of the pixels  110  receives a gate signal (i.e., a scan pulse) output from the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , or one of the gate-lines  130 _ 1  through  130 _k via the gate terminal of its switching element and receives a data signal output from one of the odd data-lines  140 _ 1  through  140 _ 5  or one of the even data-lines  150 _ 1  through  150 _ 5  via the source terminal of its switching element. 
     In some example embodiments, each of the pixels  110  includes a thin film transistor (TFT, i.e., the switching element), a liquid crystal capacitor, and a storage capacitor. Here, the liquid crystal capacitor includes a pixel electrode for receiving the data signal, a common electrode for receiving the common voltage, and a liquid crystal layer placed between the pixel electrode and the common electrode. See, for example, the representative pixel in  FIG. 2 . The liquid crystal layer includes a dielectric anisotropy material. 
     In the embodiment of  FIG. 1 , the first sub gate-line  120 _ 1  and the second sub gate-line  120 _ 2  are placed at peripheries of the display area, with the gate-lines  130 _ 1  through  130 _k therebetween. In one example embodiment, the first sub gate-line  120 _ 1  is coupled to first row-pixels that are adjacent to a lower side of the first sub gate-line  120 _ 1 . Here, “row-pixels” describe a plurality of pixels that are common to one row, including a subset of the pixels of one row (such as every other pixel). For example, in one embodiment, first row-pixels correspond to (for example, are or include) the odd column row-pixels (that is, those pixels in one row that are also in the odd columns). Likewise, the second sub gate-line  120 _ 2  is coupled to second row-pixels that are adjacent to an upper side of the second sub gate-line  120 _ 2 . For example, in one embodiment, second row-pixels correspond to (for example, are or include) even column row-pixels (that is, those pixels in one row that are also in the even columns). 
     The gate-lines  130 _ 1  through  130 _k are located (for example, placed) between the first sub gate-line  120 _ 1  and the second sub gate-line  120 _ 2 . Further, each gate-line of the gate-lines  130 _ 1  through  130 _k is coupled to second row-pixels that are adjacent to an upper side of the gate-line and to first row-pixels that are adjacent to a lower side of the gate-line. 
     In other words, each gate-line of the gate-lines  130 _ 1  through  130 _k is coupled to the pixels  110  in zigzag fashion proceeding in the row direction along the gate-line (that is, the gate-line is alternately coupled to a pixel  110  above the gate-line and to a pixel  110  below the gate-line). Here, as described above, first row-pixels correspond to (for example, are or include) odd column row-pixels and second row-pixels correspond to (for example, are or include) even column row-pixels. 
     That is, the first sub gate-line  120 _ 1  is coupled to odd column row-pixels that are adjacent to a lower side of the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2  is coupled to even column row-pixels that are adjacent to an upper side of the second sub gate-line  120 _ 2 , and each gate-line of the gate-lines  130 _ 1  through  130 _k is coupled to even column row-pixels that are adjacent to an upper side of the gate-line and to odd column row-pixels that are adjacent to a lower side of the gate-line. 
     In the embodiment of  FIG. 1 , the pixels  110  coupled to the odd data-lines  140 _ 1  through  140 _ 5  are different from the pixels  110  coupled to the even data-lines  150 _ 1  through  150 _ 5 . In other words, when the odd data-lines  140 _ 1  through  140 _ 5  are coupled to second column-pixels, then the even data-lines  150 _ 1  through  150 _ 5  are coupled to first column-pixels. Here, “column-pixels” describe a plurality of pixels that are common to one column, including a subset of the pixels of one column. For example, in one embodiment, first column-pixels correspond to (for example, are or include) odd row column-pixels (that is, those pixels in one column that are also in the odd rows) while second column-pixels correspond to (for example, are or include) even row column-pixels (that is, those pixels in one column that are also in the even rows). 
     In other embodiments, first column-pixels correspond to (for example, are or include) even row column-pixels while second column-pixels correspond to (for example, are or include) odd row column-pixels. In  FIG. 1 , it is illustrated that the odd data-lines  140 _ 1  through  140 _ 5  are coupled to even row column-pixels and that the even data-lines  150 _ 1  through  150 _ 5  are coupled to odd row column-pixels. 
     As described above, each of the pixels  110  is coupled to the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , or one of the gate-lines  130 _ 1  through  130 _k via a gate terminal of its switching element (e.g., a TFT). In addition, each of the pixels  110  is coupled to one of the odd data-lines  140 _ 1  through  140 _ 5  or one of the even data-lines  150 _ 1  through  150 _ 5  via a source terminal of its switching element (e.g., a TFT). 
     In each frame, data signals of a first polarity are applied to the odd data-lines  140 _ 1  through  140 _ 5  and data signals of a second polarity (i.e., opposite to the first polarity) are applied to the even data-lines  150 _ 1  through  150 _ 5 . As a result, data signals of the same polarity are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in the row direction. 
     In addition, data signals of alternate polarities are sequentially applied to column-pixels with an interval of one horizontal period in a column direction. That is, the LCD panel  100  substantially receives data signals in a similar way to the column inversion method. For example, in an odd frame, the odd data-lines  140 _ 1  through  140 _ 5  receive data signals of a first polarity while the even data-lines  150 _ 1  through  150 _ 5  receive data signals of a second polarity. Subsequently, in an even frame, the odd data-lines  140 _ 1  through  140 _ 5  receive data signals of the second polarity while the even data-lines  150 _ 1  through  150 _ 5  receive data signals of the first polarity. 
     The LCD panel  100  may further include the charge-sharing control circuit  160 . The charge-sharing control circuit  160  controls the odd data-lines  140 _ 1  through  140 _ 5  to share electric charges and controls the even data-lines  150 _ 1  through  150 _ 5  to share electric charges. In one example embodiment, the charge-sharing control circuit  160  includes a plurality of first switches OST and a plurality of second switches EST. The first switches OST couple the odd data-lines  140 _ 1  through  140 _ 5  to each other in accordance with a charge-sharing control signal CSC. Likewise, the second switches EST couple the even data-lines  150 _ 1  through  150 _ 5  to each other in accordance with the charge-sharing control signal CSC. 
     For example, in one example embodiment, the charge-sharing control signal CSC is a pre charge-sharing (PCS) signal. In addition, the first switches OST and the second switches EST turn on before the pixels  110  coupled to the row-lines (i.e., the first sub gate-line  120 _ 1 , the second sub gate-line  120 _ 2 , and the gate-lines  130 _ 1  through  130 _k) are charged. In another example embodiment, the first switches OST and the second switches EST turn on after the pixels  110  coupled to the row-lines are charged. Thus, the odd data-lines  140 _ 1  through  140 _ 5  share electric charges and the even data-lines  150 _ 1  through  150 _ 5  share electric charges. 
     In one example embodiment, the first switches OST and the second switches EST are implemented by n-channel metal oxide semiconductor (NMOS) transistors. In this case, when the charge-sharing control signal CSC has a logic “high” voltage level, the first switches OST and the second switches EST turn on. Accordingly, the odd data-lines  140 _ 1  through  140 _ 5  are coupled to each other and the even data-lines  150 _ 1  through  150 _ 5  are coupled to each other. 
     In another example embodiment, the first switches OST and the second switches EST are implemented by p-channel metal oxide semiconductor (PMOS) transistors. In this case, when the charge-sharing control signal CSC has a logic “low” level, the first switches OST and the second switches EST turn on. Accordingly, the odd data-lines  140 _ 1  through  140 _ 5  are coupled to each other and the even data-lines  150 _ 1  through  150 _ 5  are coupled to each other. 
     The LCD panel  100  having the charge-sharing control circuit  160  may reduce power consumption in cases such as when data signals have fickle patterns and may enhance charging-characteristics of the pixels  110  to have high performance. In  FIG. 1 , it is illustrated that the LCD panel  100  includes the charge-sharing control circuit  160 . However, the charge-sharing control circuit  160  may be embedded in an integrated circuit (IC) in other embodiments. 
     As described above, an LCD device may periodically invert polarities of data signals to reduce or prevent deterioration of a liquid crystal capacitor included in each of the pixels  110 . Here, since the LCD panel  100  has a unique structure as illustrated in  FIG. 1 , the LCD panel  100  may reduce power consumption by applying data signals of a first polarity to odd data-lines and by applying data signals of a second polarity (i.e., opposite to the first polarity) to even data-lines in each frame. 
     In addition, the LCD panel  100  may reduce or prevent horizontal crosstalk by applying data signals of the same polarity to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction. Further, the LCD panel  100  may reduce or prevent vertical crosstalk by sequentially applying data signals of alternate polarities to column-pixels with an interval of one horizontal period in a column direction. 
     In one example embodiment, each of the pixels  110  generates one of a red color, a green color, a blue color, etc. In this case, the LCD panel  100  further includes a plurality of red filters, a plurality of green filters, a plurality of blue filters, etc., on the pixels  110 . In another example embodiment, each of the pixels  110  generates one of a yellow color, a cyan color, a magenta color, etc. In this case, the LCD panel  100  further includes a plurality of yellow filters, a plurality of cyan filters, a plurality of magenta filters, etc., on the pixels  110 . Hence, the LCD panel  100  may display an image by generating various colors in accordance with a space-division method or a time-division method. 
       FIG. 2  is a diagram illustrating a structure of each pixel  110  in the LCD panel  100  of  FIG. 1 . 
     Referring to  FIG. 2 , each of the pixels  110  includes a switching element Q, a liquid crystal capacitor CLC, and a storage capacitor CST. In some example embodiments, the switching element Q may correspond to (for example, be) a thin film transistor (TFT) using amorphous silicon. 
     In the embodiment of  FIG. 2 , the switching element Q is placed on a lower display substrate. The switching element Q (e.g., a TFT) provides a data signal to the liquid crystal capacitor CLC in response to a gate signal. 
     As illustrated in  FIG. 2 , the gate signal is input from a gate-line GL and the data signal is input from a data-line DL. The switching element Q is coupled to the gate-line GL via its gate terminal, to the data-line DL via its source terminal, and to the liquid crystal capacitor CLC via its drain terminal. 
     The liquid crystal capacitor CLC is charged by a voltage difference between the data signal and a common voltage. The data signal is applied to a pixel electrode DE of the liquid crystal capacitor CLC. The common voltage is applied to a common electrode CE of the liquid crystal capacitor CLC. 
     As described above, a liquid crystal layer is placed between the pixel electrode DE and the common electrode CE. Hence, the light transmittance of the liquid crystal layer is controlled by an intensity of the electric field formed between the pixel electrode DE and the common electrode CE. This electric field intensity is also referred to as a charged voltage. 
     In case of a normally black mode, for example, the light transmittance of the liquid crystal layer may increase as the intensity of the electric field formed between the pixel electrode DE and the common electrode CE increases. On the other hand, the light transmittance of the liquid crystal layer may decrease as the intensity of the electric field formed between the pixel electrode DE and the common electrode CE decreases. 
     In some example embodiments, the liquid crystal capacitor CLC includes the pixel electrode DE formed on the lower display substrate, the common electrode CE formed on an upper display substrate, and the liquid crystal layer placed between the pixel electrode DE and the common electrode CE. However, the structure of the liquid crystal capacitor CLC is not limited thereto. 
     For example, the common electrode CE of the liquid crystal capacitor CLC may be formed on the lower display substrate. In this case, the common electrode CE may receive the common voltage from a signal line formed on the lower display substrate. In addition, the pixel electrode DE is coupled to the drain terminal of the switching element Q so that the pixel electrode DE receives the data signal from the data-line DL coupled to the source terminal of the switching element Q. 
     In one example embodiment, a low common voltage is applied to the pixels  110  when a data signal of positive polarity is applied to the pixels  110 . On the other hand, a high common voltage is applied to the pixels  110  when a data signal of negative polarity is applied to the pixels  110 . As a result, the charged voltage (i.e., the intensity of the electric field formed between the pixel electrode DE and the common electrode CE) is greater than a voltage level of the data signal so that power consumption may be substantially reduced. 
     The storage capacitor CST maintains the charged voltage of the liquid crystal capacitor CLC. That is, the storage capacitor CST assists the liquid crystal capacitor CLC. The storage capacitor CST may be formed by placing an insulator between the pixel electrode DE and the signal line. 
     In some example embodiments, the pixels  110  do not include the storage capacitor CST. The color filters may be arranged on the upper display substrate. Polarizing plates may be attached to the upper display substrate and/or the lower display substrate. 
       FIG. 3  is a timing diagram illustrating an example of providing common voltages in accordance with polarities of data signals provided to the LCD panel  100  of  FIG. 1 . 
     Referring to  FIG. 3 , a frame (i.e., a first frame  1 F and a second frame  2 F following the first frame  1 F) includes a plurality of horizontal periods  1 H through  8 H. For ease of illustration, in each of the exemplary frames  1 F and  2 F of  FIG. 3 , eight horizontal periods are shown and described. However, the frame may contain another number of horizontal periods without departing from the spirit or scope of the present invention. Here, the first frame  1 F corresponds to an odd frame and the second frame  2 F corresponds to an even frame. As described above, the LCD panel  100  displays an image in a frame unit. Hence, the LCD panel  100  generates an image by sequentially displaying a plurality of frames. 
     The first frame  1 F includes eight horizontal periods  1 H through  8 H. When gate signals (i.e., a scan pulse) are applied to the first sub gate-line  120 _ 1 , the gate-lines  130 _ 1  through  130 _k, and the second sub gate-line  120 _ 2  in the first frame  1 F, data signals output from the odd data-lines  140 _ 1  through  140 _ 5  and the even data-lines  150 _ 1  through  150 _ 5  are applied to odd column row-pixels and even column row-pixels, as illustrated in  FIG. 1 . 
     Here, a low common voltage VCOM_L is applied to the pixels  110  when data signals of positive polarity are applied to the pixels  110 . On the other hand, a high common voltage VCOM_H is applied to the pixels  110  when data signals of negative polarity are applied to the pixels  110 . 
     In detail, when data signals of positive polarity are applied to the odd data-lines  140 _ 1  through  140 _ 5  in the first frame  1 F, the low common voltage VCOM_L is applied to the common electrodes of the pixels  110  coupled to the odd data-lines  140 _ 1  through  140 _ 5  (that is, the pixels in even rows, as illustrated in the LCD panel  100  of  FIG. 1 ). On the other hand, when data signals of negative polarity are applied to the even data-lines  150 _ 1  through  150 _ 5  in the first frame  1 F, the high common voltage VCOM_H is applied to the common electrodes of the pixels  110  coupled to the even data-lines  150 _ 1  through  150 _ 5  (that is, the pixels in odd rows, as illustrated in  FIG. 1 ). 
     Similarly, when data signals of negative polarity are applied to the odd data-lines  140 _ 1  through  140 _ 5  in the second frame  2 F, the high common voltage VCOM_H is applied to the common electrodes of the pixels  110  coupled to the odd data-lines  140 _ 1  through  140 _ 5  (the pixels in even rows). On the other hand, when data signals of positive polarity are applied to the even data-lines  150 _ 1  through  150 _ 5  in the second frame  2 F, the low common voltage VCOM_L is applied to the common electrodes of the pixels  110  coupled to the even data-lines  150 _ 1  through  150 _ 5  (the pixels in odd rows). 
     Therefore, charged voltages of the liquid crystal capacitors CLC in the pixels  110  may be greater than voltage levels of data signals provided to the pixels  110 . As described above, the LCD panel  100  may substantially receive the low common voltage VCOM_L and the high common voltage VCOM_H in a similar way to the ALS inversion method (i.e., common voltages applied to the odd data-lines  140 _ 1  through  140 _ 5  and the even data-lines  150 _ 1  through  150 _ 5  may be inverted with each frame). Thus, power consumption of the LCD panel  100  may be reduced compared to the earlier described inversion methods. 
       FIG. 4  is a diagram illustrating an example of providing data signals to the LCD panel  100  of  FIG. 1  in an odd frame  1 F. 
     Referring to  FIG. 4 , when an LCD device provides data signals to the data-lines DL 1  through DL 8  of the LCD panel  100  in the odd frame  1 F, the LCD device provides data signals of a first polarity (e.g., positive polarity) to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of a second polarity (e.g., negative polarity) to the even data-lines  150 _ 1  through  150 _ 4 . In  FIG. 4 , for ease of illustration, the first eight data lines DL 1  through DL 8  (corresponding to odd data-lines  140 _ 1  through  140 _ 4  and even data lines  150 _ 1  through  150 _ 4 ) and the first eight horizontal periods  1 H through  8 H are shown and described. However, there may be another number of data lines and horizontal periods without departing from the spirit or scope of the present invention. 
     In other words, the data-lines DL 1  through DL 8  are divided into the odd data-lines  140 _ 1  through  140 _ 4  and the even data-lines  150 _ 1  through  150 _ 4  in terms of operations. For example, in the odd frame  1 F, the LCD device provides data signals of positive polarity to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of negative polarity to the even data-lines  150 _ 1  through  150 _ 4 . 
     As described above, the LCD device inverts polarities of data signals with each frame. Therefore, in the even frame  2 F following the odd frame  1 F, the LCD device provides data signals of negative polarity to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of positive polarity to the even data-lines  150 _ 1  through  150 _ 4 . 
     However, a polarity pattern as displayed on the LCD panel  100  may be different from a polarity pattern as applied to the data-lines DL 1  through DL 8 . Here, a driver polarity pattern indicates the polarity pattern as applied to the data-lines DL 1  through DL 8  (for example, odd data-lines receiving data signals of positive polarity and even data-lines receiving data signals of negative polarity), and an apparent polarity pattern indicates the polarity pattern as displayed on the LCD panel  100  (for example, pixels in odd rows receiving data signals of negative polarity and pixels in even rows receiving data signals of positive polarity, which is both rotated and inverted from the driver polarity pattern shown in  FIG. 4 ). 
     For example, a driver polarity pattern of the embodiment of the present invention shown in  FIGS. 3  (odd frame  1 F) and  4  is similar to a driver polarity pattern of the column inversion method (as illustrated in  FIG. 4 ). On the other hand, because of the characteristics of this embodiment of the present invention, namely that data signals are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction, an apparent polarity pattern of the embodiment of  FIGS. 3  (odd frame  1 F) and  4  of the present invention is similar to an apparent polarity pattern of the ALS inversion method and the line inversion method (as illustrated in  FIGS. 5A through 5E ). 
       FIGS. 5A through 5E  are diagrams illustrating an example of applying data signals to pixels of the LCD panel  100  of  FIG. 1  in a first five horizontal periods  1 H through  5 H, respectively, of an odd frame  1 F. 
     Referring to  FIG. 5A , a gate signal for turning on TFTs of the pixels  110  coupled to the first sub gate-line  120 _ 1  is provided during a first horizontal period  1 H. Since the first sub gate-line  120 _ 1  is coupled to odd column row-pixels among the pixels  110  that constitute a first row, data signals are applied to the odd column row-pixels among the pixels  110  that constitute the first row. 
     As illustrated in  FIG. 5A , the odd column row-pixels among the pixels  110  that constitute the first row are coupled to the even data-lines  150 _ 1  through  150 _ 5 . In the odd frame  1 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 5  have negative polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the first row receive data signals of negative polarity during the first horizontal period  1 H. As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the first horizontal period  1 H. 
     Referring to  FIG. 5B , a gate signal for turning on TFTs of the pixels  110  coupled to the first gate-line  130 _ 1  is provided during a second horizontal period  2 H. Since the first gate-line  130 _ 1  is coupled to even column row-pixels among the pixels  110  that constitute the first row and to odd column row-pixels among the pixels  110  that constitute a second row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the first row and to the odd column row-pixels among the pixels  110  that constitute the second row. 
     As illustrated in  FIG. 5B , the even column row-pixels among the pixels  110  that constitute the first row are coupled to the even data-lines  150 _ 1  through  150 _ 4 . In the odd frame  1 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 4  have negative polarity. Thus, the even column row-pixels among the pixels  110  that constitute the first row receive data signals of negative polarity during the second horizontal period  2 H. 
     Further, as illustrated in  FIG. 5B , the odd column row-pixels among the pixels  110  that constitute the second row are coupled to the odd data-lines  140 _ 1  through  140 _ 5 . In the odd frame  1 F, data signals applied to the odd data-lines  140 _ 1  through  140 _ 5  have positive polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the second row receive data signals of positive polarity during the second horizontal period  2 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the second horizontal period  2 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the first row of pixels in  FIG. 5B ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 5C , a gate signal for turning on TFTs of the pixels  110  coupled to the second gate-line  130 _ 2  is provided during a third horizontal period  3 H. Since the second gate-line  130 _ 2  is coupled to even column row-pixels among the pixels  110  that constitute the second row to and odd column row-pixels among the pixels  110  that constitute a third row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the second row and to the odd column row-pixels among the pixels  110  that constitute the third row. 
     As illustrated in  FIG. 5C , the even column row-pixels among the pixels  110  that constitute the second row are coupled to the odd data-lines  140 _ 2  through  140 _ 5 . In the odd frame  1 F, data signals applied to the odd data-lines  140 _ 2  through  140 _ 5  have positive polarity. Thus, the even column row-pixels among the pixels  110  that constitute the second row receive data signals of positive polarity during the third horizontal period  3 H. 
     Further, as illustrated in  FIG. 5C , the odd column row-pixels among the pixels  110  that constitute the third row are coupled to the even data-lines  150 _ 1  through  150 _ 5 . In the odd frame  1 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 5  have negative polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the third row receive data signals of negative polarity during the third horizontal period  3 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the third horizontal period  3 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the second row of pixels in  FIG. 5C ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 5D , a gate signal for turning on TFTs of the pixels  110  coupled to the third gate-line  130 _ 3  is provided during a fourth horizontal period  4 H. Since the third gate-line  130 _ 3  is coupled to even column row-pixels among the pixels  110  that constitute the third row and to odd column row-pixels among the pixels  110  that constitute a fourth row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the third row and to the odd column row-pixels among the pixels  110  that constitute the fourth row. 
     As illustrated in  FIG. 5D , the even column row-pixels among the pixels  110  that constitute the third row are coupled to the even data-lines  150 _ 1  through  150 _ 4 . In the odd frame  1 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 4  have negative polarity. Thus, the even column row-pixels among the pixels  110  that constitute the third row receive data signals of negative polarity during the fourth horizontal period  4 H. 
     Further, as illustrated in  FIG. 5D , the odd column row-pixels among the pixels  110  that constitute the fourth row are coupled to the odd data-lines  140 _ 1  through  140 _ 5 . In the odd frame  1 F, data signals applied to the odd data-lines  140 _ 1  through  140 _ 5  have positive polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the fourth row receive data signals of positive polarity during the fourth horizontal period  4 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the fourth horizontal period  4 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the third row of pixels in  FIG. 5D ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 5E , a gate signal for turning on TFTs of the pixels  110  coupled to the fourth gate-line  130 _ 4  is provided during a fifth horizontal period  5 H. Since the fourth gate-line  130 _ 4  is coupled to even column row-pixels among the pixels  110  that constitute the fourth row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the fourth row. 
     As illustrated in  FIG. 5E , the even column row-pixels among the pixels  110  that constitute the fourth row are coupled to the odd data-lines  140 _ 2  through  140 _ 5 . As described above, even column row-pixels among the pixels  110  that constitute the fourth row receive data signals of positive polarity during the fifth horizontal period  5 H of the odd frame  1 F. Further, though not specifically illustrated in  FIG. 5E , odd column row-pixels among the pixels  110  that constitute a fifth row receive data signals of negative polarity during the fifth horizontal period  5 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the fifth horizontal period  5 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the fourth row of pixels in  FIG. 5E ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     This process continues until the odd frame  1 F is finished by applying a gate signal for turning on TFTs of the pixels  110  coupled to the second sub gate-line  120 _ 2 . Then, polarities of data signals are inverted when the LCD device changes a display frame from the odd frame  1 F to the even frame  2 F. Hence, polarities of data signals in the odd frame  1 F are opposite to polarities of data signals in the even frame  2 F following the odd frame  1 F. 
     As illustrated in  FIGS. 5A through 5E , a driver polarity pattern of the embodiment of the present invention shown in  FIGS. 3  (odd frame  1 F) and  4  is similar to a driver polarity pattern of the column inversion method (as displayed in  FIG. 4 ). In addition, because of the characteristics of this embodiment of the present invention, namely that data signals are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction, an apparent polarity pattern of the embodiment of  FIGS. 3  (odd frame  1 F) and  4  of the present invention is similar to an apparent polarity pattern of the ALS inversion method and the line inversion method. 
       FIG. 6  is a diagram illustrating an example of providing data signals to the LCD panel  100  of  FIG. 1  in an even frame  2 F. 
     Referring to  FIG. 6 , when an LCD device provides data signals to the data-lines DL 1  through DL 8  of the LCD panel  100  in the even frame  2 F, the LCD device provides data signals of a second polarity (e.g., negative polarity) to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of a first polarity (e.g., positive polarity) to the even data-lines  150 _ 1  through  150 _ 4 . In  FIG. 6 , for ease of illustration, the first eight data lines DL 1  through DL 8  (corresponding to odd data-lines  140 _ 1  through  140 _ 4  and even data lines  150 _ 1  through  150 _ 4 ) and the first eight horizontal periods  1 H through  8 H are shown and described. However, there may be another number of data lines and horizontal periods without departing from the spirit or scope of the present invention. 
     In other words, the data-lines DL 1  through DL 8  are divided into the odd data-lines  140 _ 1  through  140 _ 4  and the even data-lines  150 _ 1  through  150 _ 4  in terms of operations. For example, in the even frame  2 F, the LCD device provides data signals of negative polarity to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of positive polarity to the even data-lines  150 _ 1  through  150 _ 4 . 
     As described above, the LCD device inverts polarities of data signals with each frame. Therefore, in the first frame  1 F following the second frame  2 F, the LCD device provides data signals of positive polarity to the odd data-lines  140 _ 1  through  140 _ 4  and provides data signals of negative polarity to the even data-lines  150 _ 1  through  150 _ 4 . 
     However, a polarity pattern as displayed on the LCD panel  100  may be different from a polarity pattern as applied to the data-lines DL 1  through DL 8 . Here, a driver polarity pattern indicates the polarity pattern as applied to the data-lines DL 1  through DL 8  (for example, odd data-lines receiving data signals of negative polarity and even data-lines receiving data signals of positive polarity), and an apparent polarity pattern indicates the polarity pattern as displayed on the LCD panel  100  (for example, pixels in odd rows receiving data signals of positive polarity and pixels in even rows receiving data signals of negative polarity, which is both rotated and inverted from the driver polarity pattern shown in  FIG. 6 ). 
     For example, a driver polarity pattern of an embodiment of the present invention shown in  FIGS. 3  (even frame  2 F) and  6  is similar to a driver polarity pattern of the column inversion method (as illustrated in  FIG. 6 ). On the other hand, because of the characteristics of this embodiment of the present invention, namely that data signals are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction, an apparent polarity pattern of the embodiment of  FIGS. 3  (even frame  2 F) and  6  of the present invention is similar to an apparent polarity pattern of the ALS inversion method and the line inversion method (as illustrated in  FIGS. 7A through 7E ). 
       FIGS. 7A through 7E  are diagrams illustrating an example of applying data signals to pixels of the LCD panel  100  of  FIG. 1  in a first five horizontal periods  1 H through  5 H, respectively, of an even frame  2 F. 
     Referring to  FIG. 7A , a gate signal for turning on TFTs of the pixels  110  coupled to the first sub gate-line  120 _ 1  is provided during a first horizontal period  1 H. Since the first sub gate-line  120 _ 1  is coupled to odd column row-pixels among the pixels  110  that constitute a first row, data signals are applied to the odd column row-pixels among the pixels  110  that constitute the first row. 
     As illustrated in  FIG. 7A , the odd column row-pixels among the pixels  110  that constitute the first row are coupled to the even data-lines  150 _ 1  through  150 _ 5 . In the even frame  2 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 5  have positive polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the first row receive data signals of positive polarity during the first horizontal period  1 H. As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the first horizontal period  1 H. 
     Referring to  FIG. 7B , a gate signal for turning on TFTs of the pixels  110  coupled to the first gate-line  130 _ 1  is provided during a second horizontal period  2 H. Since the first gate-line  130 _ 1  is coupled to even column row-pixels among the pixels  110  that constitute the first row and to odd column row-pixels among the pixels  110  that constitute a second row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the first row and to the odd column row-pixels among the pixels  110  that constitute the second row. 
     As illustrated in  FIG. 7B , the even column row-pixels among the pixels  110  that constitute the first row are coupled to the even data-lines  150 _ 1  through  150 _ 4 . In the even frame  2 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 4  have positive polarity. Thus, the even column row-pixels among the pixels  110  that constitute the first row receive data signals of positive polarity during the second horizontal period  2 H. 
     Further, as illustrated in  FIG. 7B , the odd column row-pixels among the pixels  110  that constitute the second row are coupled to the odd data-lines  140 _ 1  through  140 _ 5 . In the even frame  2 F, data signals applied to the odd data-lines  140 _ 1  through  140 _ 5  have negative polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the second row receive data signals of negative polarity during the second horizontal period  2 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the second horizontal period  2 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the first row of pixels in  FIG. 7B ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 7C , a gate signal for turning on TFTs of the pixels  110  coupled to the second gate-line  130 _ 2  is provided during a third horizontal period  3 H. Since the second gate-line  130 _ 2  is coupled to even column row-pixels among the pixels  110  that constitute the second row and to odd column row-pixels among the pixels  110  that constitute a third row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the second row and to the odd column row-pixels among the pixels  110  that constitute the third row. 
     As illustrated in  FIG. 7C , the even column row-pixels among the pixels  110  that constitute the second row are coupled to the odd data-lines  140 _ 2  through  140 _ 5 . In the even frame  2 F, data signals applied to the odd data-lines  140 _ 2  through  140 _ 5  have negative polarity. Thus, the even column row-pixels among the pixels  110  that constitute the second row receive data signals of negative polarity during the third horizontal period  3 H. 
     Further, as illustrated in  FIG. 7C , the odd column row-pixels among the pixels  110  that constitute the third row are coupled to the even data-lines  150 _ 1  through  150 _ 5 . In the even frame  2 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 5  have positive polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the third row receive data signals of positive polarity during the third horizontal period  3 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the third horizontal period  3 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the second row of pixels in  FIG. 7C ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 7D , a gate signal for turning on TFTs of the pixels  110  coupled to the third gate-line  130 _ 3  is provided during a fourth horizontal period  4 H. Since the third gate-line  130 _ 3  is coupled to even column row-pixels among the pixels  110  that constitute the third row and to odd column row-pixels among the pixels  110  that constitute a fourth row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the third row and to the odd column row-pixels among the pixels  110  that constitute the fourth row. 
     As illustrated in  FIG. 7D , the even column row-pixels among the pixels  110  that constitute the third row are coupled to the even data-lines  150 _ 1  through  150 _ 4 . In the even frame  2 F, data signals applied to the even data-lines  150 _ 1  through  150 _ 4  have positive polarity. Thus, the even column row-pixels among the pixels  110  that constitute the third row receive data signals of positive polarity during the fourth horizontal period  4 H. 
     Further, as illustrated in  FIG. 7D , the odd column row-pixels among the pixels  110  that constitute the fourth row are coupled to the odd data-lines  140 _ 1  through  140 _ 5 . In the even frame  2 F, data signals applied to the odd data-lines  140 _ 1  through  140 _ 5  have negative polarity. Thus, the odd column row-pixels among the pixels  110  that constitute the fourth row receive data signals of negative polarity during the fourth horizontal period  4 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the fourth horizontal period  4 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the third row of pixels in  FIG. 7D ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     Referring to  FIG. 7E , a gate signal for turning on TFTs of the pixels  110  coupled to the fourth gate-line  130 _ 4  is provided during a fifth horizontal period  5 H. Since the fourth gate-line  130 _ 4  is coupled to even column row-pixels among the pixels  110  that constitute the fourth row, data signals are applied to the even column row-pixels among the pixels  110  that constitute the fourth row. 
     As illustrated in  FIG. 7E , the even column row-pixels among the pixels  110  that constitute the fourth row are coupled to the odd data-lines  140 _ 2  through  140 _ 5 . As described above, even column row-pixels among the pixels  110  that constitute the fourth row receive data signals of negative polarity during the fifth horizontal period  5 H of the even frame  2 F. Further, though not specifically illustrated in  FIG. 5E , odd column row-pixels among the pixels  110  that constitute a fifth row receive data signals of positive polarity during the fifth horizontal period  5 H. 
     As a result, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are not applied to adjacent row-pixels at the same time during the fifth horizontal period  5 H (that is, adjacent row-pixels receiving data signals of the same polarity do so during different horizontal periods, as illustrated in the fourth row of pixels in  FIG. 7E ). Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are applied to adjacent column-pixels. 
     This process continues until the even frame  2 F is finished by applying a gate signal for turning on TFTs of the pixels  110  coupled to the second sub gate-line  120 _ 2 . Then, polarities of data signals are inverted when the LCD device changes a display frame from the even frame  2 F to the odd frame  1 F. Hence, polarities of data signals in the even frame  2 F are opposite to polarities of data signals in the odd frame  1 F following the even frame  2 F. 
     As illustrated in  FIGS. 7A through 7E , a driver polarity pattern of the embodiment of the present invention shown in  FIGS. 3  (even frame  2 F) and  6  is similar to a driver polarity pattern of the column inversion method (as displayed in  FIG. 6 ). In addition, because of the characteristics of this embodiment of the present invention, namely that data signals are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction, an apparent polarity pattern of the embodiment of  FIGS. 3  (even frame  2 F) and  6  of the present invention is similar to an apparent polarity pattern of the ALS inversion method and the line inversion method. 
       FIG. 8  is a diagram illustrating another LCD panel  500  in accordance with example embodiments. 
     Referring to  FIG. 8 , the LCD panel  500  includes a plurality of pixels  510 , a first sub gate-line  520 _ 1 , a second sub gate-line  520 _ 2 , a plurality of gate-lines  530 _ 1  through  530 _k, a plurality of odd data-lines  540 _ 1  through  540 _ 5 , and a plurality of even data-lines  550 _ 1  through  550 _ 5 . The first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , and the plurality of gate-lines  530 _ 1  through  530 _k are collectively referred to as row-lines. According to some example embodiments, the LCD panel  500  further includes a charge-sharing control circuit  560 . In the embodiment of  FIG. 8 , for ease of illustration, five odd data lines  540 _ 1  through  540 _ 5  and five even data lines  550 _ 1  through  550 _ 5  are shown and described. However, the LCD panel  500  may contain another number of data lines without departing from the spirit or scope of the present invention. 
     The pixels  510  are arranged in a matrix manner (that is, in rows and columns) at portions corresponding to crossing regions of the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , the gate-lines  530 _ 1  through  530 _k, the odd data-lines  540 _ 1  through  540 _ 5 , and the even data-lines  550 _ 1  through  550 _ 5 . Here, each of the pixels  510  is coupled to the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , or one of the gate-lines  530 _ 1  through  530 _k via a gate terminal of its switching element (e.g., a TFT). Additionally, each of the pixels  510  is coupled to one of the odd data-lines  540 _ 1  through  540 _ 5  or one of the even data-lines  550 _ 1  through  550 _ 5  via a source terminal of its switching element (e.g., a TFT). As a result, each of the pixels  510  receives a gate signal (i.e., a scan pulse) output from the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , or one of the gate-lines  530 _ 1  through  530 _k via the gate terminal of its switching element (e.g., a TFT) and receives a data signal output from one of the odd data-lines  540 _ 1  through  540 _ 5  or one of the even data-lines  550 _ 1  through  550 _ 5  via the source terminal of its switching element (e.g., a TFT). 
     In the embodiment of  FIG. 8 , the first sub gate-line  520 _ 1  and the second sub gate-line  520 _ 2  are placed at peripheries of the display area, with the gate-lines  530 _ 1  through  530 _k therebetween. In one example embodiment, the first sub gate-line  520 _ 1  is coupled to first row-pixels (for example, even column row-pixels) that are adjacent to a lower side of the first sub gate-line  520 _ 1 . Likewise, the second sub gate-line  520 _ 2  is coupled to second row-pixels (for example, odd column row-pixels) that are adjacent to an upper side of the second sub gate-line  520 _ 2 . 
     The gate-lines  530 _ 1  through  530 _k are located (for example, placed) between the first sub gate-line  520 _ 1  and the second sub gate-line  520 _ 2 . Further, each gate-line of the gate-lines  530 _ 1  through  530 _k is coupled to second row-pixels that are adjacent to an upper side of the gate-line and to first row-pixels that are adjacent to a lower side of the gate-line. 
     In other words, each gate-line of the gate-lines  530 _ 1  through  530 _k is coupled to the pixels  510  in zigzag fashion proceeding in the row direction along the gate-line (that is, the gate-line is alternately coupled to a pixel  110  above the gate-line and to a pixel  110  below the gate-line). Here, as described above, first row-pixels correspond to (for example, are or include) even column row-pixels and second row-pixels correspond to (for example, are or include) odd column row-pixels. 
     That is, the first sub gate-line  520 _ 1  is coupled to even column row-pixels that are adjacent to a lower side of the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2  is coupled to odd column row-pixels that are adjacent to an upper side of the second sub gate-line  520 _ 2 , and each gate-line of the gate-lines  530 _ 1  through  530 _k is coupled to odd column row-pixels that are adjacent to an upper side of the gate-line and even column row-pixels that are adjacent to a lower side of the gate-line. 
     In the embodiment of  FIG. 8 , the pixels  510  coupled to the odd data-lines  540 _ 1  through  540 _ 5  are different from the pixels  510  coupled to the even data-lines  550 _ 1  through  550 _ 5 . In other words, when the odd data-lines  540 _ 1  through  540 _ 5  are coupled to second column-pixels, then the even data-lines  550 _ 1  through  550 _ 5  are coupled to first column-pixels. Here, “column-pixels” describe a plurality of pixels that are common to one column, including a subset of the pixels of one column. For example, in one embodiment, first column-pixels correspond to (for example, are or include) odd row column-pixels and second column-pixels correspond to (for example, are or include) even row column-pixels. 
     In other embodiments, first column-pixels correspond to (for example, are or include) even row column-pixels while second column-pixels correspond to (for example, are or include) odd row column-pixels. In  FIG. 8 , it is illustrated that the odd data-lines  540 _ 1  through  540 _ 5  are coupled to even row column-pixels and that the even data-lines  550 _ 1  through  550 _ 5  are coupled to odd row column-pixels. 
     As described above, each of the pixels  510  is coupled to the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , or one of the gate-lines  530 _ 1  through  530 _k via a gate terminal of its switching element (e.g., a TFT). In addition, each of the pixels  510  is coupled to one of the odd data-lines  540 _ 1  through  540 _ 5  or one of the even data-lines  550 _ 1  through  550 _ 5  via a source terminal of its switching element (e.g., a TFT). 
     In each frame, data signals of a first polarity are applied to the odd data-lines  540 _ 1  through  540 _ 5  and data signals of a second polarity (i.e., opposite to the first polarity) are applied to the even data-lines  550 _ 1  through  550 _ 5 . As a result, data signals of the same polarity are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in the row direction. 
     In addition, data signals of alternate polarities are sequentially applied to column-pixels with an interval of one horizontal period in a column direction. That is, the LCD panel  500  substantially receives data signals in a similar way to the column inversion method. For example, in an odd frame, the odd data-lines  540 _ 1  through  540 _ 5  receive data signals of a first polarity and the even data-lines  550 _ 1  through  550 _ 5  receive data signals of a second polarity. Subsequently, in an even frame, the odd data-lines  540 _ 1  through  540 _ 5  receive data signals of the second polarity and the even data-lines  550 _ 1  through  550 _ 5  receive data signals of the first polarity. 
     The LCD panel  500  may further include the charge-sharing control circuit  560 . The charge-sharing control circuit  560  controls the odd data-lines  540 _ 1  through  540 _ 5  to share electric charges and controls the even data-lines  550 _ 1  through  550 _ 5  to share electric charges. In one example embodiment, the charge-sharing control circuit  560  includes a plurality of first switches OST and a plurality of second switches EST. The first switches OST couple the odd data-lines  540 _ 1  through  540 _ 5  to each other in accordance with a charge-sharing control signal CSC. Likewise, the second switches EST couple the even data-lines  550 _ 1  through  550 _ 5  to each other in accordance with the charge-sharing control signal CSC. 
     For example, in one example embodiment, the charge-sharing control signal CSC is a pre charge-sharing (PCS) signal. In addition, the first switches OST and the second switches EST turn on before the pixels  510  coupled to the row-lines (i.e., the first sub gate-line  520 _ 1 , the second sub gate-line  520 _ 2 , and the gate-lines  530 _ 1  through  530 _k) are charged. In another example embodiment, the first switches OST and the second switches EST turn on after the pixels  510  coupled to the row-lines are charged. Thus, the odd data-lines  540 _ 1  through  540 _ 5  share electric charges and the even data-lines  550 _ 1  through  550 _ 5  share electric charges. 
     Therefore, the LCD panel  500  having the charge-sharing control circuit  560  may reduce power consumption in cases such as when the data signals have fickle patterns and may enhance charging-characteristics of the pixels  510  to have high performance. In  FIG. 8 , it is illustrated that the LCD panel  500  includes the charge-sharing control circuit  560 . However, the charge-sharing control circuit  560  may be embedded in an integrated circuit (IC) in other embodiments. 
       FIG. 9  is a block diagram illustrating an LCD device  1000  in accordance with example embodiments. 
     Referring to  FIG. 9 , the LCD device  1000  includes an LCD panel  100 , a source driver  200 , a gate driver  300 , and a timing controller  400 . Although not illustrated in  FIG. 9 , the LCD device  1000  may further include a gradation voltage generator that generates a plurality of gradation voltages. The gradation voltage generator may be coupled, for example, to the source driver  200 . 
     The LCD panel  100  displays an image in accordance with data signals output from the source driver  200  and gate signals (i.e., a scan pulse) output from the gate driver  300 . The LCD panel  100  includes a plurality of pixels. In a row direction, the pixels are divided into odd column row-pixels and even column row-pixels. In a column direction, the pixels are divided into odd row column-pixels and even row column-pixels. 
     As described above, “row-pixels” describe a plurality of pixels that are common to one row (including a subset of the pixels of one row, such as every other pixel) and “column-pixels” describe a plurality of pixels that are common to one column (including a subset of the pixels of one column, such as every other pixel). In the LCD panel  100 , data signals of the same polarity are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in the row direction. In addition, data signals of opposite polarities are sequentially applied to column-pixels with an interval of one horizontal period in the column direction. For these operations, the LCD panel  100  includes the pixels, the first sub gate-line, the second sub gate-line, the gate-lines, the odd data-lines, and the even data-lines as described earlier (see, for example,  FIGS. 1 and 8 ). 
     The pixels are arranged in a matrix manner (that is, in rows and columns) at portions corresponding to crossing regions of the first sub gate-line, the second sub gate-line, the gate-lines, the odd data-lines, and the even data-lines. The first sub gate-line is coupled to first row-pixels that are adjacent to a lower side of the first sub gate-line and the second sub gate-line is coupled to second row-pixels that are adjacent to an upper side of the second sub gate-line. For instance, first row-pixels may correspond to (for example, are or include) the odd column row-pixels while second row-pixels may correspond to (for example, are or include) the even-column row-pixels. 
     The gate-lines are located (for example, placed) between the first sub gate-line and the second sub gate-line. Here, each of the gate-lines is coupled to second row-pixels that are adjacent to an upper side of the each of the gate-lines and first row-pixels that are adjacent to a lower side of the each of the gate-lines. In other words, each of the gate-lines is coupled to the pixels in zigzag fashion proceeding in the row direction along the gate-line. 
     The odd data-lines are coupled to second column-pixels that are adjacent to the odd data-lines. The even data-lines are coupled to first column-pixels that are adjacent to the even data-lines. For instance, second column-pixels may correspond to (for example, are or include) the even row column-pixels while first column-pixels may correspond to (for example, are or include) the odd row column-pixels. 
     The LCD panel  100  may further include a charge-sharing control circuit. The charge-sharing control circuit controls the odd data-lines to share electric charges and controls the even data-lines to share electric charges. 
     As described above, first row-pixels correspond to (for example, are or include) odd column row-pixels and second row-pixels correspond to (for example, are or include) even column row-pixels. In other embodiments, first row-pixels correspond to (for example, are or include) even column row-pixels and second row-pixels correspond to (for example, are or include) odd column row-pixels. Furthermore, as described above, first column-pixels correspond to (for example, are or include) odd row column-pixels and second column-pixels correspond to (for example, are or include) even row column-pixels. In other embodiments, first column-pixels correspond to (for example, are or include) even row column-pixels and second column-pixels correspond to (for example, are or include) odd row column-pixels. 
     In the LCD device  1000  of  FIG. 9 , the source driver  200  applies data signals to the data-lines DL 1  through DLm of the LCD panel  100  in accordance with a data control signal DCS. The data control signal DCS is output from the timing controller  400 . Here, data signals are generated by selecting gradation voltages generated by the gradation voltage generator (which is part of, or coupled to, the source driver  200 ). In some example embodiments, the gradation voltage generator may generate pairs of gradation voltages (i.e., one has positive polarity relative to a common voltage and another has negative polarity relative to the common voltage). 
     The source driver  200  determines polarities of data signals by selecting gradation voltages of positive polarity or gradation voltages of negative polarity. Hence, data signals may have positive polarity relative to the common voltage or negative polarity relative to the common voltage. 
     In some example embodiments, the data control signal DCS includes a polarity control signal that controls polarities of data signals. In accordance with the polarity control signal, the LCD device  1000  periodically inverts polarities of data signals applied to the data-lines DL 1  through DLm. In each frame, for example, the LCD device  1000  may apply data signals of a first polarity to even data-lines and may apply data signals of a second polarity to odd data-lines. 
     As described above, the LCD device  1000  inverts polarities of data signals (from a first polarity to a second polarity) provided to the LCD panel  100  with each frame (i.e., when the LCD device  1000  changes display frames from an odd frame to an even frame and from an even frame to an odd frame). For example, the first polarity may correspond to (for example, is) positive polarity while the second polarity corresponds to (for example, is) negative polarity. In other embodiments, the first polarity may correspond to (for example, is) negative polarity while the second polarity corresponds to (for example, is) positive polarity. 
     Continuing with the LCD device  1000  of  FIG. 9 , the gate driver  300  applies gate signals to gate-lines GL 1  through GLn of the LCD panel  100  in accordance with a gate control signal GCS. The gate control signal GCS is output from the timing controller  400 . In each frame, the gate signals are sequentially shifted (i.e., a scan pulse). 
     In addition, the timing controller  400  generates the gate control signal GCS and the data control signal DCS, which control driving timings for the LCD device  1000 . In some example embodiments, the timing controller  400  receives a RGB image signal, a horizontal synchronization signal H, a vertical synchronization signal V, a main clock CLK, a data enable signal DES, etc., from an external graphic controller (not part of the LCD device  1000 ), and generates the gate control signal GCS and the data control signal DCS in accordance with these received signals. 
     For example, the gate control signal GCS may include a vertical synchronization start signal that controls an output start timing of gate signals, a gate clock signal that controls an output timing of gate signals, an output enable signal that controls a duration time of gate signals, etc. In addition, the data control signal DCS may include a horizontal synchronization start signal that controls an input start timing of data signals, a load signal that applies data signals to the data-lines DL 1  through DLm, a polarity control signal that periodically inverts polarities of the data signals, etc. 
       FIG. 10  is a flow chart illustrating a method of driving the LCD device  1000  of  FIG. 9 . 
     Referring to  FIG. 10 , the LCD device  1000  displays an image in a frame unit. As described above, each frame includes a plurality of horizontal periods. In the method of  FIG. 10 , data signals of the same polarity are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction (Step S 120 ). Further, data signals of opposite polarities are sequentially applied to column-pixels with an interval of one horizontal period in a column direction (Step S 140 ). Subsequently, polarities of data signals provided to the LCD panel  100  are inverted with each frame (Le., when the LCD device  1000  changes display frames from an odd frame to an even frame and from an even frame to an odd frame). 
     Through Steps S 120  and S 140 , the method of  FIG. 10  may reduce or prevent horizontal crosstalk and vertical crosstalk while efficiently reducing power consumption. In detail, horizontal crosstalk may be reduced or prevented because data signals of the same polarity are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction (Step S 120 ). For example, during a first horizontal period, data signals of a first polarity may be concurrently (e.g., simultaneously) applied to odd column row-pixels among a plurality of pixels that constitute a first row. Then, during a second horizontal period, data signals of a first polarity may be concurrently (e.g., simultaneously) applied to even column row-pixels among the pixels that constitute the first row. 
     Further, vertical crosstalk may be reduced or prevented because data signals of opposite polarities are sequentially applied to column-pixels with an interval of one horizontal period in a column direction (Step S 140 ). For example, during a first horizontal period, data signals of a first polarity are applied to the first row column-pixels. Then, during a second horizontal period, data signals of a second polarity are applied to the corresponding second row column-pixels. Then, during a third horizontal period, data signals of the first polarity are applied to the corresponding third row column-pixels. Then, during a fourth horizontal period, data signals of the second polarity are applied to the corresponding fourth row column-pixels, etc. 
     Steps S 120  and S 140  may be performed, for example, in a frame unit. That is, in order to reduce or prevent deterioration of liquid crystal capacitors in the pixels due to polarization, the method of  FIG. 10  inverts polarities of data signals provided to the LCD panel  100  with each frame (Step S 160 ). For example, in a first frame (e.g., an odd frame), data signals applied to odd data-lines may have a first polarity while data signals applied to even data-lines may have a second polarity. Then, in a second frame (e.g., an even frame), data signals applied to odd data-lines have the second polarity while data signals applied to even data-lines have the first polarity. Then, in a third frame (e.g., an odd frame), data signals applied to odd data-lines have the first polarity while data signals applied to even data-lines have the second polarity. 
     Here, power consumption may be efficiently reduced because polarities of data signals are inverted with respect to alternating data-lines. As described above, a driver polarity pattern of an embodiment of the present invention may be similar to a driver polarity pattern of the column inversion method. On the other hand, because of the characteristics of this embodiment of the present invention, namely that data signals are applied to odd column row-pixels and even column row-pixels with an interval of one horizontal period in a row direction, an apparent polarity pattern of this embodiment of the present invention is similar to an apparent polarity pattern of the ALS inversion method and the line inversion method.
