For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein should be interpreted accordingly. 
     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, connected to, or coupled to the other element or layer, or one or more intervening elements or layers may be present. In addition, it will also be understood that when an element or layer is referred to as being “between” two elements or layers, it can be the only element or layer between the two elements or layers, or one or more intervening elements or layers may also be present. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and “including,” when used in this specification, specify the presence of the 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. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. 
     As used herein, the term “substantially,” “about,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent deviations in measured or calculated values that would be recognized by those of ordinary skill in the art. Further, the use of “may” when describing embodiments of the present invention refers to “one or more embodiments of the present invention.” As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively. Also, the term “exemplary” is intended to refer to an example or illustration. 
     The electronic or electric devices and/or any other relevant devices or components according to embodiments of the present invention described herein may be implemented utilizing any suitable hardware, firmware (e.g. an application-specific integrated circuit), software, or a combination of software, firmware, and hardware. For example, the various components of these devices may be formed on one integrated circuit (IC) chip or on separate IC chips.

     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/or the present specification, and should not be interpreted in an idealized or overly formal sense, unless expressly so defined herein. 
       FIG. 1  is a view illustrating a display device DD according to an embodiment of the present disclosure. 
     Referring to  FIG. 1 , the display device DD may include a display surface DD-IS. The display surface DD-IS may be located at a front surface of the display device DD. 
     The display device DD may display an image IM through the display surface DD-IS. The display surface DD-IS is parallel to a surface defined by a first direction DR 1  and a second direction DR 2 . A normal direction of the display surface DD-IS, i.e., a thickness direction of the display device DD with respect to the display surface DD-IS, is a third direction DR 3 . 
     A front surface (or top surface) and a back surface (or bottom surface) of each member or unit described hereinbelow is distinguished by the third direction DR 3 . However, the first to third directions DR 1 , DR 2 , and DR 3  illustrated in this embodiment are merely illustrative, and the directions indicated by the first to third directions DR 1 , DR 2 , and DR 3  are relative concepts, and may be changed into other directions or orientations. Hereinafter, first to third directions are directions respectively indicated by the first to third directions DR 1 , DR 2 , and DR 3 , and are designated by like reference numerals. 
     In an embodiment of the present disclosure, the display device DD including a planar display surface DD-IS is illustrated, but the present disclosure is not limited thereto. The display device DD may include a curved display surface DD-IS or a stereoscopic display surface DD-IS. 
     The display device DD according to the embodiment of the present disclosure, may be a rigid display device. However, the present disclosure is not limited thereto, and the display device DD according to the embodiment of the present disclosure, may be a flexible display device. 
     In the depicted embodiment, a display device DD that is applicable to a mobile phone terminal is, as an example, illustrated. Although not shown in the drawing, electronic modules, a camera module, a power module, and the like, which are mounted on a main board, are located together with the display device DD in a bracket/case, etc., thereby constituting a mobile phone terminal. 
     The display device DD according to embodiments of the present disclosure may be applied to large-sized electronic devices such as televisions and monitors, as well as medium and small-sized electronic devices such as tablet PCs, vehicle navigation systems, game consoles, smart watches, head mounted displays, and the like. 
     The display surface DD-IS includes a display area DD-DA in which the image IM is displayed and a non-display area DD-NDA adjacent to the display area DD-DA. 
     The non-display area DD-NDA may be an area in which the image IM is not displayed. In  FIG. 1 , temperature and weather images are illustrated as an example of the image IM. 
     The non-display area DD-NDA may surround the display area DD-DA. 
     As shown in  FIG. 1 , the display area DD-DA may have a quadrangular shape. The present disclosure, however, is not limited thereto, and the display area DD-DA and the non-display area DD-NDA may be designed in various shapes (e.g., a rhombus shape, a circular shape, an elliptical shape, an irregular shape, and the like). 
       FIGS. 2A and 2B  are views illustrating sections of display devices according to embodiments of the present disclosure. 
       FIGS. 2A and 2B  illustrate sections of the display devices, which are defined by a second direction DR 2  and a third direction DR 3 .  FIGS. 2A and 2B  are simply illustrated to describe stacking relationships between a functional panel and/or functional units, which constitute the display devices. 
     A display device according to an embodiment of the present disclosure may include a display panel, an input sensing unit, and a window unit. At least some components among the display panel, the input sensing unit, and the window unit may be formed by a continuous process. Alternatively, at least some components among the display panel, the input sensing unit, and the window unit may be coupled to each other through an adhesive member. In  FIG. 2 , an optically transparent adhesive member OCA is illustrated as a representative example of the adhesive member. The adhesive member described hereinbelow may include a general adhesive or gluing agent. 
     It should be understood that when a component is formed with another component through a continuous process between the input sensing unit and the window unit, the components may be collectively referred to as a “layer.” 
     Similarly, for components between the input sensing unit and the window unit, when a component is coupled to another component through an adhesive member the components may collectively referred to as a “panel.” 
     The “panel” includes a base layer that provides a base surface, e.g., a synthetic resin film, a composite material film, a glass substrate, and the like, but the base layer may be omitted in the “layer.” In other words, the units each expressed as the “layer” are located (e.g., disposed) on a base surface provided by another unit. 
     The input sensing unit and the window unit may be designated as an input sensing panel and a window panel or an input sensing layer and a window layer depending on the presence of a base layer. 
     In this specification, that component A is directly disposed or located on component B means that any separate adhesive layer/adhesive member is not between the component A and the component B. Thus, the component B is formed on a base surface provided by the component A through a continuous process after the component A is formed. 
     Referring to  FIG. 2A , the display device DD may include a display panel DP, a panel moving unit PMU, an input sensing layer ISL, and a window panel WP. 
     The display panel DP may generate an image. 
     The panel moving unit may be disposed (e.g., located) under the display panel DP. For example, the panel moving unit PMU may entirely or partially overlap with the display panel DP. 
     The panel moving unit PMU may be connected between the display panel DP and an external case (not shown), to move the display panel DP. For example, the panel moving unit PMU may reciprocate the display panel DP along one or more directions. 
     In some embodiments, the panel moving unit PMU may move (e.g., reciprocate) the display panel DP along any one of a variety of suitable directions. For example, the panel moving unit PMU may move the display panel according to a quadrangular shape, a circular shape, or any other regular or irregular shape. In some embodiments, the panel moving unit PMU may move the display panel in a reciprocating fashion, such that the display panel travels a distance in a repetitive back and forth motion along a first direction. For example, the display panel DP may start at a first location and panel moving unit PMU may move the display panel DP in a first direction for a distance to a second location. The panel moving unit PMU may then move the display panel DP in a second direction that is opposite to the first direction for the distance to return to the first location. Thus, the panel moving unit PMU may reciprocate the display panel DP along a first direction. 
     In some embodiments, the panel moving unit PMU may move the display panel DP along any one of at least two directions. 
     Several embodiments of the present disclosure will be described with reference to  FIGS. 7A to 9C . 
     In some embodiments, the input sensing layer ISL may be directly disposed on the display panel DP. When the input sensing layer ISL is directly disposed on the display panel, the display panel DP and the input sensing layer ISL may be collectively referred to as a display module. 
     An optically transparent adhesive member OCA may be disposed (e.g., located) between the display module and the window panel WP. 
     The window panel WP may protect the display panel DP and the input sensing layer ISL from the outside. 
     In an embodiment of the present disclosure, the display panel DP may be a light emitting display panel, but is not particularly limited. For example, the display panel DP may be an organic light emitting display panel, a quantum dot light emitting display panel, or any other suitable display panel known to those skilled in the art. An emitting layer of the organic light emitting display panel may include an organic light emitting material. An emitting layer of the quantum dot light emitting display panel may include a quantum dot, a quantum rod, and the like. Hereinafter, the display panel DP is described as the organic light emitting display panel. 
     The input sensing layer ILS may sense a user input (e.g., a touch, a pressure, a fingerprint, etc.). That is, the input sensing layer ISL may acquire coordinate information and/or pressure information based on the user input. 
       FIG. 2  illustrates that the input sensing layer ISL entirely overlaps with the display panel DP. 
     Referring to  FIGS. 1 and 2A , the input sensing layer ISL may entirely overlap with the display area DD-DA. However, the present disclosure is not limited thereto, and the input sensing layer ISL may partially overlap with the display area DD-DA, or overlap with only the non-display area DD-NDA. 
     The input sensing layer ISL may be a touch sensing panel for sensing a touch of a user or a fingerprint sensing panel for sensing fingerprint information of a finger of the user. 
     Referring to  FIG. 2B , the display device DD′ may include a display panel DP, a first panel moving unit PMU 1 , a second panel moving unit PMU 2 , an input sensing layer ISL, and a window panel WP. 
     In order to avoid redundancy, contents overlapping with those illustrated in  FIG. 2A  are not described, and the contents illustrated in  FIG. 2A  may be applied as they are. 
     The first and second panel moving units PMU 1  and PMU 2  may be located (e.g., disposed) under the display panel DP. For example, the first and second panel moving units PMU 1  and PMU 2  may entirely or partially overlap with the display panel DP. 
     The first and second panel moving units PMU 1  and PMU 2  may be connected between the display panel DP and an external case (not shown), to move the display panel DP. For example, each of the first and second panel moving units PMU 1  and PMU 2  may move (e.g., reciprocate) the display panel DP along a direction or along a plurality of directions. That is, for example, the first panel moving unit PMU 1  may move the display panel DP along the first direction DR 1  (see  FIG. 1 ), and the second panel moving unit PMU 2  may move the display panel DP along the second direction DR 2  (see  FIG. 1 ) different from the first direction DR 1 . 
     However, the present disclosure is not limited thereto, and the panel moving unit PMU may be designed in various manners within a range achieving the advantages of the present disclosure. 
       FIG. 3  is a block diagram illustrating a display panel DP according to an embodiment of the present disclosure. 
     Referring to  FIG. 3 , the display panel DP may include a pixel unit  110 , a scan driver  120 , a data driver  130 , an emission driver  140 , and a timing controller  150 . 
     In  FIG. 3 , the scan driver  120 , the data driver  130 , the emission driver  140 , and the timing controller  150  are individually illustrated, but at least some of the components may be integrated according to example embodiments of this disclosure. 
     The scan driver  120 , the data driver  130 , the emission driver  140 , and the timing controller  150  may be installed in various suitable ways including chip on glass, chip on plastic, tape carrier package, chip on film, and/or the like. 
     The pixel unit  110  may correspond to the display area DD-DA (see  FIG. 1 ) of the display device DD. 
     The pixel unit  110  may include a plurality of pixels PXL. For example, the plurality of pixels PXL may be disposed (e.g., located) on a base substrate (not shown). 
     The pixels PXL may be connected to scan lines S 1  to Sn (where n is a natural number). Therefore, the pixels PXL may receive scan signals from the scan driver  120  through the scan lines S 1  to Sn. 
     The pixels PXL may be connected to data lines D 1  to Dm (where m is a natural number). Therefore, the pixels PXL may receive data signals from the data driver  130  through the data lines D 1  to Dm. 
     The pixels PXL may be connected to emission control lines E 1  to En. Therefore, the pixels PXL may receive emission control signals from the emission driver  140  through the emission control lines E 1  to En. 
     The pixel unit  110  may receive a first power source ELVDD, a second power source ELVSS, and a third power source Vint from a power supply unit (not shown). 
     The pixels PXL may be arranged in a matrix structure. 
     For example, the pixels PXL may be arranged at intersection portions of the scan lines S 1  to Sn and the data lines D 1  to Dm. 
     In some embodiments, the pixels PXL may be arranged at intersection portions of the emission control lines E 1  to En and the data lines D 1  to Dm. 
     Although  FIG. 3  illustrates n scan lines S 1  to Sn and n emission control lines E 1  to En, the present disclosure is not limited thereto. In some embodiments, dummy scan lines or dummy emission control lines may be additionally formed so as to ensure the stability of driving. 
     The pixels PXL may be connected to the scan lines S 1  to Sn, the data lines D 1  to Dm, and the emission control lines E 1  to En. 
     For example, the pixels PXL may receive scan signals through the scan lines S 1  to Sn, receive emission control signals through the emission control lines E 1  to En, and receive data signals through the data lines D 1  to Dm. 
     Each of the pixels PXL may store a voltage corresponding to a data signal supplied thereto. 
     The pixels PXL may be supplied with the first power source ELVDD, the second power source ELVSS, and the third power source Vint. 
     In some embodiments, the first power source ELVDD may have a voltage higher than that of the second power source ELVSS. Each of the first power source ELVDD and the second power source ELVSS may have any one of a high-level voltage and a low-level voltage. 
     The third power source Vint may have a preset voltage. For example, the third power source Vint may have a voltage lower than that of the data signal. 
     However, the present disclosure is not limited thereto, and each of the first power source ELVDD, the second power source ELVSS, and the third power source Vint may have a voltage within a range (e.g., a predetermined range). 
     Each of the pixels PXL may control an amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via an organic light emitting diode (not shown), based on the stored voltage. The organic light emitting diode may generate light with a luminance corresponding to the amount of driving current. 
     The pixels PXL may be driven in units of frames. 
     In some embodiment, each of the pixels PXL may include a plurality of sub-pixels arranged in a subsampled structure such as a PENTILE® structure (e.g., an RGBG structure). PENTILE® is a registered trademark of Samsung Display Co., Ltd., Republic of Korea. For example, each of the pixels PXL may include two first sub-pixels, a second sub-pixel, and a third sub-pixel. The first sub-pixels may emit green light, the second sub-pixel may emit red light, and the third sub-pixel may emit blue light. The sub-pixel arrangement will be described in detail with reference to  FIG. 4 . 
     The scan driver  120  may receive a scan driving control signal from the timing controller  150 . For example, the scan driving control signal may include clock signals and a scan start signal. The scan start signal may control supply timings of scan signals, and the clock signals may be used to shift the scan start signal. 
     The scan driver  120  may generate scan signals in response to the scan driving control signal. For example, the scan signals may have a gate-on voltage at which transistors included in the pixels PXL can be turned on. 
     The scan driver  120  may be connected to the scan lines S 1  to Sn. 
     The scan driver  120  may supply scan signals to the scan lines S 1  to Sn. For example, the scan driver  120  may sequentially the scan signals to the scan lines S 1  to Sn. 
     The data driver  130  may receive a data driving control signal and image data from the timing controller  150 . For example, the data driving control signal may include a source start signal, a source output enable signal, a source sampling clock, and the like. The source start signal may control a data sampling start time of the data driver  130 . The source sampling clock may control a sampling operation of the data driver  130 , based a rising or falling edge. The source output enable signal may control an output timing of the data driver  130 . 
     The data driver  130  may generate data signals, based on a data driving control signal and the image data. For example, the data signals may have voltages within a predetermined range corresponding to the image data. 
     The data driver  130  may be connected to the data lines D 1  to Dm. 
     The data driver  130  may supply data signals to the data lines D 1  to Dm. For example, the data driver  130  may supply the data signals to the data lines D 1  to Dm to be synchronized with the sequentially supplied scan signals. 
     In this specification, the data signal may have a voltage within a range (e.g., a predetermined range) corresponding to the image data. 
     The emission driver  140  may receive an emission driving control signal from the timing controller  150 . For example, the emission driving control signal may include clock signals and an emission start signal. The emission start signal may control supply timings of emission control signals, and the clock signals may be used to shift the emission start signal. 
     The emission driver  140  may generate emission control signals in response to the emission driving control signal. For example, the emission control signals may have the gate-on voltage at which the transistors included in the pixels PXL can be turned on. 
     The emission driver  140  may be connected to the emission control lines E 1  to En. 
     The emission driver  140  may supply emission control signals to the emission control lines E 1  to En. For example, the emission driver  140  may sequentially supply the emission control signals to the emission control lines E 1  to En. 
     The timing controller  150  may drive the display panel DP or the pixels PXL in units of frame periods. 
     The timing controller  150  may receive, from a host system (not shown), image data and timing signals (e.g., a vertical synchronization signal, a horizontal synchronization signal, a data enable signal, a clock signal, and the like). 
     The timing controller  150  may control the components (e.g., the pixel unit  110 , the scan driver  120 , the data driver  130 , and the emission driver  140 ) of the display panel DP, based on the image data and the timing signals. 
     For example, the timing controller  150  may transmit the scan driving control signal to the scan driver  120 , transmit the data driving control signal to the data driver  130 , and transmit the emission driving control signal to the emission driver  140 . 
       FIG. 4  is a view illustrating a pixel emission area PEA according to an embodiment of the present disclosure. 
       FIG. 4  illustrates a pixel emission area PEA that is an emission area of the pixel PXL shown in  FIG. 3 . For example,  FIG. 4  illustrates a pixel emission area PEA on a plane defined by a first direction DR 1  and a second direction DR 2 . 
     The pixel emission area PEA corresponds to one pixel PXL (see  FIG. 3 ), and means emission areas of the pixel PXL on a plane defined by the first direction DR 1  and the second direction DR 2 . 
     Referring to  FIG. 4 , each pixel PXL may include a plurality of sub-pixels. In some embodiments, each pixel PXL may include a plurality of sub-pixels arranged in a sub-sampled sub-pixel structure such as a PENTILE® structure. 
     For example, each pixel PXL may include two first sub-pixels, a second sub-pixel, and a third sub-pixel. The first sub-pixels may emit green light, the second sub-pixel may emit red light, and the third sub-pixel may emit blue light. 
     Each of the first sub-pixels may emit green light through a first emission area EA 1 . 
     The second sub-pixel may emit red light through a second emission area EA 2 . 
     The third sub-pixel may emit blue light through a third emission area EA 3 . 
     For example, the first to third emission areas EA 1 , EA 2 , and EA 3  may correspond to an area in which an anode electrode of an organic light emitting diode OLED (see  FIG. 5 ) is exposed on a plane, an area in which an organic light emitting material on the anode electrode is located on the plane, etc. However, the present disclosure is not limited thereto. 
     In some embodiments, the second emission area EA 2  and the third emission area EA 3  may be wider than the first emission area EA 1 . 
     The first emission areas EA 1  of the first sub-pixels may be located (e.g., disposed) on the same horizontal line. The second emission area EA 2  of the second sub-pixel and the third emission area EA 3  of the third sub-pixel may be located (e.g., disposed) on the same horizontal line. The second emission area EA 2  and the third emission area EA 3  may be located (e.g., disposed) on a horizontal line different from that of the first emission area EA 1 . 
     As shown in  FIG. 4 , in one pixel emission area PEA, the first emission area EA 1 , the second emission area EA 2 , and the third emission area EA 3  may be located (e.g., disposed) on different vertical lines. 
     That is, the second emission area EA 2  and the third emission area EA 3  may be located diagonally from the first emission areas EA 1  (e.g. along a third direction that is a third direction with respect to the first direction DR 1  and the second direction DR 2 ). In various embodiments, the third direction (e.g., a diagonal direction) may bisect the first direction DR 1  and the second direction DR 2 . For example, if the first direction DR 1  is perpendicular to the second direction DR 2 , the third direction may be 45 degrees from the first and second directions DR 1  and DR 2 . However, in other embodiments, the third direction may include any angle relative to the first direction DR 1  and the second direction DR 2 . 
       FIG. 5  is a view illustrating a sub-pixel SPXL according to an embodiment of the present disclosure. 
       FIG. 5  illustrates a circuit diagram of any one of the plurality of sub-pixels included in the pixel PXL shown in  FIG. 3 . 
     Referring to  FIG. 5 , the sub-pixel SPXL may include an organic light emitting diode OLED and a pixel circuit PXC.

     The organic light emitting diode OLED may generate light with a predetermined luminance corresponding to a driving current supplied from the pixel circuit PXC. 
     The organic light emitting diode OLED may include an emitting layer that emits light of one of primary colors. For example, the primary colors may include at least one of red, green, blue, and white. 
     A first power source ELVDD may be set to a voltage higher than that of the second power source ELVSS such that a current can flow through the organic light emitting diode OLED. 
     The pixel circuit PXC may control an amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED, corresponding to a data signal.

     A first electrode of the first transistor (driving transistor) T 1  may be connected to the first power source ELVDD through the sixth transistor T 6 , and a second electrode of the first transistor T 1  may be connected to the anode electrode of the organic light emitting diode OLED. In addition, a gate electrode of the first transistor T 1  may be connected to a first node N 1 . 
     The first transistor T 1  may control an amount of driving current flowing from the first power source ELVDD to the second power source ELVSS via the organic light emitting diode OLED, corresponding to a voltage of the first node N 1 . 
     The first node N 1  refers to a node commonly connected to the gate electrode of the first transistor T 1 , the third transistor T 3 , the fourth transistor T 4 , and the storage capacitor Cst. 
     The second transistor T 2  may be connected between a data line from which a data signal DAT is supplied and a second node N 2 . In addition, a gate electrode of the second transistor T 2  may be connected to a scan line from which a first gate signal GW is supplied. The second transistor T 2  may be turned on when the first gate signal GW is supplied to the scan line. For example, the first gate signal GW may be an ith scan signal (where i is a natural number) supplied to an ith scan line. 
     When the second transistor T 2  is turned on, the data signal DAT is supplied from the data line and the second node N 2  may be electrically connected to each other. Therefore, the data signal DAT may be applied to the second node N 2 . 
     The second node N 2  refers to a node commonly connected to the first transistor T 1 , the second transistor T 2 , and the sixth transistor T 6 . 
     The third transistor T 3  may be connected between the second electrode of the first transistor T 1  and the first node N 1 . In addition, a gate electrode of the third transistor T 3  may be connected to the scan line through which the first gate signal GW is supplied. The third transistor T 3  may be turned on when the first gate signal GW is supplied to the scan line. 
     When the third transistor T 3  is turned on, the second electrode of the first transistor T 1  and the first node N 1  may be electrically connected to each other. Therefore, the first transistor T 1  may be diode-connected. 
     The fourth transistor T 4  may be connected between the first node N 1  and a third power source Vint. In addition, a gate electrode of the fourth transistor T 4  may be connected to a scan line through which a second gate signal GI is supplied. The fourth transistor T 4  may be turned on when the second gate signal GI is supplied to the scan line. For example, the second gate signal GI may be an (i−1)th scan signal supplied to an (i−1)th scan line. 
     However, the present disclosure is not limited thereto. In some embodiment, the second gate signal GI may be a scan signal supplied to any one of scan lines S 1  to Si−2. 
     When the fourth transistor T 4  is turned on, the first node N 1  and the third power source Vint may be electrically connected to each other. Therefore, the third power source Vint may be applied to the first node N 1 , and the first node N 1  may be initialized to the voltage of the third power source Vint. 
     The fifth transistor T 5  may be connected between the anode electrode of the organic light emitting diode OLED and the third power source Vint. In addition, a gate electrode of the fifth transistor T 5  may be connected to the scan line through which the first gate signal GW is supplied. The fifth transistor T 5  may be turned on when the first gate signal GW is supplied to the scan line. 
     When the fifth transistor T 5  is turned on, the anode electrode of the organic light emitting diode OLED and the third power source Vint may be electrically connected to each other. Therefore, the third power source Vint may be applied to the anode electrode of the organic light emitting diode OLED, and the anode electrode of the organic light emitting diode OLED may be initialized to the voltage of the third power source Vint. 
     The sixth transistor T 6  and the seventh transistor T 7  may be located on a path of driving current. 
     The sixth transistor T 6  may be connected between the second node N 2  and the first power source ELVDD. In addition, a gate electrode of the sixth transistor T 6  may be connected to an emission control line through which an emission control signal EM is supplied. The sixth transistor T 6  may be turned on when the emission control signal EM is supplied to the emission control line. For example, the emission control signal EM may be an ith emission control signal supplied to an ith emission control line. 
     The seventh transistor T 7  may be connected between the anode electrode of the organic light emitting diode OLED and the second power source ELVSS. In addition, a gate electrode of the seventh transistor T 7  may be connected to the emission control line through which the emission control signal EM is supplied. The seventh transistor T 7  may be turned on when the emission control signal EM is supplied to the emission control line. 
     The storage capacitor Cst may be connected between the first power source ELVDD and the first node N 1 . The storage capacitor Cst may store a voltage corresponding to the data signal DAT and a threshold voltage of the first transistor T 1 . 
     In  FIG. 5 , an embodiment in which the first to seventh transistors T 1  to T 7  are implemented with a P-channel MOS transistor is representatively described. It should be understood that in some embodiments, an equivalent N-channel MOS transistor circuit may be implemented, as those skilled in the art would appreciate. 
       FIG. 6  is a waveform diagram illustrating a driving method of the sub-pixel SPXL (see  FIG. 5 ) according to an embodiment of the present disclosure. 
     Referring to  FIGS. 5 and 6 , the sub-pixel SPXL may display one image during a frame period FP. The display panel DP (see  FIG. 3 ) and the pixels PXL (see  FIG. 3 ) may be driven in units of frames. 
     Hereinafter, it is described that the emission control signal EM, the first gate signal GW, and the second gate signal GI have a gate-on voltage. In  FIG. 6 , the gate-on voltage is illustrated as a low-level voltage, and a gate-off voltage is illustrated as a high-level voltage. 
     According to the embodiment of the driving method of the sub-pixel SPXL shown in  FIG. 6 , the frame period FP may include a first sub-frame period SF 1  and a second sub-frame period SF 2 . However, the present disclosure is not limited thereto, and it will be apparent that the frame period FP may include one sub-frame period or three or more sub-frame periods. 
     Each of the first sub-frame period SF 1  and the second sub-frame period SF 2  may include a first period SP 1  and a second period SP 2 . 
     For example, the first period SP 1  may mean a non-emission period, and the second period SP 2  may mean an emission period. 
     The first period SP 1  and the second period SP 2  may be sequentially continued. 
     During the first period SP 1 , the second gate signal GI and the first gate signal GW may be sequentially supplied to the scan lines. In addition, the data signal DAT may be supplied to the data line in synchronization with the first gate signal GW. 
     When the second gate signal GI is supplied, the fourth transistor T 4  may be turned on. When the fourth transistor T 4  is turned on, the first node N 1  may be initialized to the voltage of the third power source Vint. 
     When the first gate signal GW is supplied, the second transistor T 2 , the third transistor T 3 , and the fifth transistor T 5  may be turned on. 
     When the second transistor T 2  is turned on, the voltage of the data signal DAT supplied through the data line may be applied to the second node N 2 . 
     When the third transistor T 3  is turned on, the first transistor T 1  may be diode-connected. A voltage obtained by subtracting the threshold voltage of the first transistor T 1  from the voltage of the data signal DAT may be applied to the first node N 1 . Therefore, the storage capacitor Cst may store a voltage corresponding to the difference between the voltage of the first power source ELVDD and the voltage applied to the first node N 1 . Thus, the threshold voltage of the first transistor T 1  can be compensated. 
     When the fifth transistor T 5  is turned on, the voltage of the third power source Vint may be applied to the anode electrode of the organic light emitting diode OLED. Therefore, the anode electrode of the organic light emitting diode OLED may be initialized to the voltage of the third power source Vint. 
     During the second period SP 2 , the emission control signal EM may be supplied. 
     When the emission control signal EM is supplied, the sixth transistor T 6  and the seventh transistor T 7  may be turned on. 
     When the sixth transistor T 6  and the seventh transistor T 7  are turned on, the driving current flows through the organic light emitting diode OLED, and the organic light emitting diode OLED may generate light (e.g., predetermined light). Therefore, the sub-pixel SPXL may emit light. 
     Thus, based on the contents illustrated in  FIGS. 5 and 6 , the plurality of pixels PXL can emit lights during each of the first sub-frame period SF 1  and the second sub-frame period SF 2 . 
       FIGS. 7A and 7B  are views illustrating a driving method of the display device according to an embodiment of the present disclosure. 
     Referring to  FIG. 7A , a frame period FP may include a first sub-frame period SF 1  and a second sub-frame period SF 2 . 
     A driving frequency DF exemplarily illustrated in  FIG. 7A  may mean a frequency at which the display panel DP (see  FIG. 3 ) is driven based on the contents illustrated in  FIGS. 3 to 6 . 
     A motion frequency VF exemplarily illustrated in  FIG. 7A  may refer to a frequency at which the panel moving unit PMU (see  FIG. 2A ) is driven according to example embodiments of the present disclosure. 
     As shown in  FIG. 7A , the motion frequency VF may correspond to the driving frequency DF. Therefore, during each of the first sub-frame period SF 1  and the second sub-frame period SF 2 , the panel moving unit PMU (see  FIG. 2A ) may move the display panel DP (see  FIG. 3 ) along a preset motion path. 
       FIG. 7B  illustrates a pixel emission area PEA of the pixel PXL (see  FIG. 3 ) of the display panel DP (see  FIG. 3 ), which is moved by the panel moving unit PMU (see  FIG. 2A ) during each of the first sub-frame period SF 1  and the second sub-frame period SF 2 . For convenience of description, only the first emission area EA 1  and the second emission area EA 2  in the pixel emission area PEA shown in  FIG. 4  are illustrated in  FIG. 7B , but contents described in  FIG. 7B  may be applied to the other areas. 
     Referring to  FIGS. 2A, 3, 7A, and 7B , the panel moving unit PMU may move (e.g., reciprocate) the display panel DP along a third direction DRD during the frame period FP. 
     The third direction DRD may mean a third direction with respect to the first direction DR 1  and the second direction DR 2 . 
     In some embodiments, as the panel moving unit PMU is driven, the display panel DP may be moved. For example, the display panel DP may be moved such that the first emission area EA 1  is moved to an initial state (e.g., a first initial position) for the first sub-frame period SF 1 . Additionally, the display panel DP may be moved such that the first emission area EA 1  is moved to an initial state (e.g., a second initial position) for the second sub-frame period SF 2 . The initial state may mean a state before the display panel DP is moved by the panel moving unit PMU. 
     In some embodiments, during the frame period FP, the panel moving unit PMU may move (e.g., reciprocate) the display panel DP by a distance DDD (e.g., a diagonal distance) along the third direction DRD. The distance DDD may mean a distance between the first emission area EA 1  and the second emission area EA 2 . 
     For example, as the panel moving unit PMU is driven, the display panel DP may be moved by the diagonal distance DDD to one side of the third direction DRD during the first sub-frame period SF 1 . In addition, the display panel DP may be moved by the diagonal distance DDD to the other side of (e.g., opposite to) the third direction during the second sub-frame period SF 2 . 
     Although  FIG. 7B  illustrates that the panel moving unit PMU linearly moves the display panel DP, the present disclosure is not limited thereto. In some embodiments, the panel moving unit PMU may move the display panel DP along at least one of a curve, a bent line, and a combination thereof. 
       FIGS. 8A and 8B  are views illustrating a driving method of the display device according to an embodiment of the present disclosure. 
     Referring to  FIG. 8A , a frame period FP may include first to fourth sub-frame periods SF 1 , SF 2 , SF 3 , and SF 4 . 
     A driving frequency DF exemplarily illustrated in  FIG. 8A  may mean a frequency at which the display panel DP (see  FIG. 3 ) is driven based on the contents illustrated in  FIGS. 3 to 6 . 
     A motion frequency VF exemplarily illustrated in  FIG. 8A  may refer to a frequency at which the panel moving unit PMU (see  FIG. 2A ) is driven according to example embodiments of the present disclosure. 
     As shown in  FIG. 8A , the motion frequency VF may correspond to the driving frequency DF. Therefore, during each of the first to fourth sub-frame periods SF 1 , SF 2 , SF 3 , and SF 4 , the panel moving unit PMU (see  FIG. 2A ) may move the display panel DP (see  FIG. 3 ) along a motion path (e.g., a preset motion path). 
       FIGS. 8B and 8C  illustrate a pixel emission area PEA of the pixel PXL (see  FIG. 3 ) of the display panel DP (see  FIG. 3 ), which is moved by the panel moving unit PMU (see  FIG. 2A ) during each of the first to fourth sub-frame periods SF 1 , SF 2 , SF 3 , and SF 4 . For convenience of description, only the first emission area EA 1  and the second emission area EA 2  in the pixel emission area PEA shown in  FIG. 4  are illustrated in  FIGS. 8B and 8C , but contents described in  FIGS. 8B and 8C  may be applied to the other areas. 
     Referring to  FIGS. 2A, 3, 8A, and 8B , the panel moving unit PMU may reciprocate the display panel DP according to a shape during the frame period FP. The shape may, for example include at least one of a quadrangular shape, a circular shape, or any other suitable shape. 
     For example, as the panel moving unit PMU is driven, the display panel DP may be moved such that the first emission area EA 1  is moved to a position where the first emission area EA 1  is in an initial state (e.g., an a first initial location) during the first sub-frame period SF 1 . In various embodiments, the locations at which the panel moving unit PMU positions the display panel may be considered different states. In some embodiments, the display panel DP may be moved such that the first emission area EA 1  is moved to a position of a non-emission area (e.g., an area that does not include the first emission area EA 1  and the second emission area EA 2  in the pixel emission area PEA) in the initial state (e.g., at a second initial location) during the second sub-frame period SF 2 . In another example, the display panel DP may be moved such that the first emission area EA 1  is moved to a position of the second emission area EA 2  in the initial state (e.g., at a third initial location) during the third sub-frame period SF 3 . In yet another example, the display panel DP may be moved such that the first emission area EA 1  is moved to a position of the non-emission area in the initial state (e.g., at a fourth initial location) during the fourth sub-frame period SF 4 . Thus, in this example, the display panel DP may be moved so that the various emission areas (e.g., the first emission area EA 1  and the second emission area EA 2 ) may sequentially move through  4  different locations. 
     As shown in  FIG. 8B , the position of the non-emission area may be variously set. 
     In some embodiments, the panel moving unit PMU may reciprocate the display panel DP along a quadrangular shape during the frame period FP. 
     For example, as the panel moving unit PMU is driven, the display panel DP may be moved by a first distance D 1  to one side of the first direction DR 1  during the first sub-frame period SF 1 . Additionally, the display panel DP may be moved by a second distance D 2  to one side of the second direction DR 2  during the second sub-frame period SF 2 . The display panel DP may be moved by the first distance D 1  to the other side of the first direction DR 1  (e.g., opposite to the first side of the first direction DR 1 ) during the third sub-frame period SF 3 . The display panel DP may be moved by the second distance D 2  to the other side of the second direction DR 2  (e.g., opposite to the first side of the second direction DR 2 ) during the fourth sub-frame period SF 4 . For example, in some embodiments, the panel moving unit PMU may move the display panel DP to the right by a first distance D 1 , up by a second distance D 2 , left by the first distance D 1 , and down by the second distance D 2  and may reciprocate the display panel DP along this path. 
     The first distance D 1  may mean a distance between the first emission area EA 1  and the second emission area EA 2  according to the first direction DR 1 , and the second distance D 2  may mean a distance between the first emission area EA and the second emission area EA 2  according to the second direction DR 2 . 
     In some embodiments, the first distance DR 1  and the second distance D 2  may be the same. 
     Although  FIG. 8B  illustrates that the panel moving unit PMU linearly moves the display panel DP, the present disclosure is not limited thereto. In some embodiments, the panel moving unit PMU may move the display panel DP along at least one of a curve, a bent line, and a combination thereof. 
     Referring to  FIGS. 2A, 3, 8A, and 8C , the panel moving unit PMU may move (e.g., reciprocate) the display panel DP along a circular shape during the frame period FP. 
     The diameter of the circular shape may be equal to the distance between the first emission area EA 1  and the second emission area EA 2 . 
       FIGS. 9A and 9B  are views illustrating a driving method of the display device according to an embodiment of the present disclosure. 
     Referring to  FIG. 9A , the display panel DP (see  FIG. 3 ) may be driven in units of frame periods FP without separate time-divisionally driving. 
     A driving frequency DF exemplarily illustrated in  FIG. 9A  may mean a frequency at which the display panel DP (see  FIG. 3 ) is driven based on the contents illustrated in  FIGS. 3 to 6 . 
     A motion frequency VF exemplarily illustrated in  FIG. 9A  may refer to a frequency at which the panel moving unit PMU (see  FIG. 2A ) is driven according to example embodiments of the present disclosure. 
     As shown in  FIG. 9A , the motion frequency VF may correspond to k times (where k is a natural number of 2 or more) the driving frequency DF. Therefore, during the frame period FP, the panel moving unit PMU (see  FIG. 2A ) may move the display panel DP (see  FIG. 3 ) along a motion path (e.g., along a preset motion path). 
     In  FIG. 9A , a case where the motion frequency VF is ten times of the driving frequency DF is illustrated as an example. However, the present disclosure is not limited thereto. 
       FIGS. 9B and 9C  illustrate a pixel emission area PEA of the pixel PXL (see  FIG. 3 ) of the display panel DP (see  FIG. 3 ), which is moved by the panel moving unit PMU (see  FIG. 2A ) during the frame period FP. For convenience of description, only the first emission area EA 1  and the second emission area EA 2  in the pixel emission area PEA shown in  FIG. 4  are illustrated in  FIGS. 9B and 9C , but contents described in  FIGS. 9B and 9C  may be applied to the other areas. 
     Referring to  FIGS. 2A, 3, 9A, and 9B , the panel moving unit PMU may reciprocate the display panel at least twice in the first direction DR 1  during the frame period FP. 
     For example, as the panel moving unit PMU is driven, the display panel DP may be reciprocated at least twice between a first position and a second position. For example, the display panel DP may be reciprocated at least twice between an initial state position of the first emission area EA 1  (e.g., at an initial location) and a position of the non-emission area in the initial state during the frame period FP. The initial state may mean a state (e.g., a location) before the display panel DP is moved by the panel moving unit PMU. 
     In some embodiments, the panel moving unit PMU may reciprocate the display panel DP at least twice by a first distance D 1  in the first direction DR 1  during the frame period FP. 
     Although  FIG. 9B  illustrates that the panel moving unit PMU linearly moves the display panel DP, the present disclosure is not limited thereto. In some embodiments, the panel moving unit PMU may move the display panel DP along at least one of a curve, a bent line, and a combination thereof. 
     Referring to  FIGS. 2A, 3, 9A, and 9C , the panel moving unit PMU may reciprocate the display panel DP at least twice in the second direction DR 2  during the frame period. 
     For example, as the panel driving unit PMU is driven, the display panel DP may be reciprocated at least twice between a position of the first emission area EA 1  in the initial state and a position of the non-emission area in the initial state during the frame period FP. 
     In some embodiments, the panel driving unit PMU may reciprocate the display panel DP at least twice by a second distance D 2  in the second direction DR 2  during the frame period FP. 
     Although  FIG. 9C  illustrates that the panel moving unit PMU linearly moves the display panel DP, the present disclosure is not limited thereto. In some embodiments, the panel moving unit PMU may move the display panel DP along at least one of a curve, a bent line, and a combination thereof. 
     Thus, the display device according to the present disclosure can improve resolution and image quality by moving the display panel. 
     Further, the display device according to the present disclosure can prevent a screen door effect by improving a fill factor. 
     The fill factor means a ratio of an emission area per unit area of a display surface, and the screen door effect means that a non-emission area between emission areas is viewed by a user. 
     Example embodiments have been disclosed herein, and although specific terms are employed, they are used and are to be interpreted in a generic and descriptive sense only and not for purpose of limitation. In some instances, as would be apparent to one of ordinary skill in the art as of the filing of the present application, features, characteristics, and/or elements described in connection with a particular embodiment may be used singly or in combination with features, characteristics, and/or elements described in connection with other embodiments unless otherwise specifically indicated.
