Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to liquid crystal display (LCD) technology, and more specifically, to a LCD panel and a method of forming the same. 
         [0003]    2. Description of the Prior Art 
         [0004]    Quantum rod (QR), like quantum dot (QD), is a nanomaterial formed by a limited number of semiconductor atoms. Different from quasi-zero-dimensional QD, QR is a one dimensional material whose size in one direction is far larger than that in the other two directions. The structural anisotropy results in an optical anisotropy, which is unique to QR materials. The optical anisotropy refers to the fact that the direction of the long axis of the QR is much more capable than the direction perpendicular to the long axis in light absorption and emission. The polarization efficiency of QRs can be as high as 96%, equivalent to the polarization efficiency of iodine-based polarizers, which is the mainstream. 
         [0005]    An alignment of QRs is needed during the application process to ensure that all QRs are parallel to the same direction, so to fully make use of the optical anisotropy of the QRs. Currently, the QRs are aligned by thin film extension technology, which requires independent production of extension thin films and introduction of extension technology. The production process is more complicated and the QR alignment efficiency is low. In addition, current display appliances can only show a limited variety of colors, instead of different greyscale images of the same color. 
         [0006]    Therefore, it is necessary to provide a LCD panel and a method of forming the same to solve the problems with the existing technology. 
       SUMMARY OF THE INVENTION 
       [0007]    An object of the present invention is to provide a LCD panel and a method of forming the same to solve problems with the existing technology of LCD panels, including low color gamut and high production cost. 
         [0008]    According to the present invention, a liquid crystal display (LCD) panel, comprises a first substrate, a second substrate, a second polarizer, and a liquid crystal layer. The first substrate comprises a first base substrate, an isolation layer, disposed on the first base substrate, comprising a plurality of isolators, and a first polarizer, disposed on an external side of the first substrate. The second substrate is disposed opposite to the first substrate. The second substrate comprises a switch array layer, data lines and scan lines surrounding a plurality of pixel units comprising red, green and blue pixels. The switch array layer comprises a plurality of thin film transistors. The second polarizer is disposed on an external side of the second substrate. The liquid crystal layer comprises one or more red liquid crystal units, one or more green liquid crystal units and one or more blue liquid crystal units. One of the isolators is disposed between two adjacent liquid crystal units. Liquid crystal molecules of the red liquid crystal units and green liquid crystal units are mixed with quantum rods (QRs) of corresponding colors. The red liquid crystal units correspond to a position of the red pixels, the green liquid crystal units correspond to a position of the green pixels, and the blue liquid crystal units correspond to a position of the blue pixels. The QRs and liquid crystal molecules have long axes and directions of the long axes of QRs and liquid crystal molecules are the same. 
         [0009]    When the TFTs are closed, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate. Under light of a backlight source, the polarization direction of the second polarizer is the same as the long axes of the QRs close to the side of the second substrate. The QRs rotate with the liquid crystal molecules, so that the direction of the long axes of the QRs close to the side of the first substrate is the same as the polarization direction of the first polarizer. The LCD panel is in a first state of brightness. Spacers are disposed on the first substrate; the material of the spacers is the same as the isolators.

         [0012]    Furthermore, when the TFTs are not fully opened, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second polarizer and the long axes of the QRs close to the side of the second substrate form a set angle. The QRs turn with the liquid crystal molecules, so that the long axes of the QRs close to the side of the first substrate and the polarization direction of the first polarizer form a set angle. The LCD panel is in a second state of brightness. 
         [0013]    Furthermore, when the TFTs are fully opened, the QRs, along with the liquid crystal molecules, turn to align perpendicularly to the first substrate spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second polarizer is perpendicular to the long axes of the QRs close to the second substrate, while the long axes of the QRs close to the first substrate is perpendicular to the polarization direction of the first polarizer. The LCD panel is in a third state of brightness. The first state of brightness is larger the second state of brightness, and the second state of brightness is larger than the third state of brightness.

The first substrate comprises a first base substrate, and an isolation layer, disposed on the first base substrate, comprising a plurality of isolators. The second substrate, disposed opposite to the first substrate, comprises data lines and scan lines surrounding a plurality of pixel units comprising red, green and blue pixels. The liquid crystal layer comprises one or more red liquid crystal units, one or more green liquid crystal units and one or more blue liquid crystal units. One of the isolators is disposed between two adjacent liquid crystal units. Liquid crystal molecules of the red liquid crystal units and green liquid crystal units are mixed with quantum rods (QRs) of corresponding colors. The red liquid crystal units correspond to a position of the red pixels, the green liquid crystal units correspond to a position of the green pixels, and the blue liquid crystal units correspond to a position of the blue pixels. The QRs and liquid crystal molecules have long axes and directions of the long axes of QRs and liquid crystal molecules are the same. 
         [0017]    Furthermore, the liquid crystal molecules of the red liquid crystal units are mixed with red QRs. The liquid crystal molecules of the green liquid crystal units are mixed with green QRs. The liquid crystal molecules of the blue liquid crystal units are mixed with blue QRs.

A second polarizer is disposed on an external side of the second substrate, and a first polarizer is disposed on an external side of the first substrate. 
         [0020]    When the TFTs are closed, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second polarizer is the same as the long axes of the QRs close to the side of the second substrate. The QRs rotate with the liquid crystal molecules, so that the direction of the long axes of the QRs close to the side of the first substrate is the same as the polarization direction of the first polarizer. The LCD panel is in a first state of brightness. 
         [0021]    When the TFTs are not fully opened, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate.

The LCD panel is in a second state of brightness. 
         [0022]    When the TFTs are fully opened, the QRs, along with the liquid crystal molecules, turn to align perpendicularly to the first substrate spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second polarizer is perpendicular to the long axes of the QRs close to the second substrate, while the long axes of the QRs close to the first substrate is perpendicular to the polarization direction of the first polarizer. The LCD panel is in a third state of brightness. 
         [0023]    The first state of brightness is larger the second state of brightness, and the second state of brightness is larger than the third state of brightness. 
         [0024]    Furthermore, spacers are disposed on the first substrate; the material of the spacers is the same as the isolators.

         [0027]    Furthermore, the method comprises dripping the liquid crystal molecules that are not mixed with the QRs to the position corresponding to the blue pixels by means of ink-jetting. 
         [0028]    Furthermore, the second substrate further comprises a switch array layer comprising a plurality of thin film transistors (TFTs). A second polarizer is disposed on an external side of the second substrate, and a first polarizer is disposed on an external side of the first substrate.

Under the light of the backlight source, the polarization direction of the second polarizer is the same as the long axes of the QRs close to the side of the second substrate. The QRs rotate with the liquid crystal molecules, so that the direction of the long axes of the QRs close to the side of the first substrate is the same as the polarization direction of the first polarizer. The LCD panel is in a first state of brightness. 
         [0030]    When the TFTs are not fully opened, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0040]    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. 
         [0041]    Please refer to  FIG. 1 .  FIG. 1  is a structure diagram of a LCD panel of a first embodiment of the present invention. 
         [0042]    The LCD panel of the present invention comprises a first substrate  20 , a second substrate  10 , and a liquid crystal layer, disposed between the first substrate  20  and the second substrate  10 . The first substrate  20 , e.g. is a color film substrate, and the second substrate  10 , e.g. is an array substrate. The first substrate  20  comprises a first base substrate  21 , and a first polarizer  22  disposed on an external side of the first substrate. A color resist layer can further be disposed on the first base substrate. The color resist layer comprises a red color film  26 , green color film  27  and blue color film  28 . A black matrix  23  can be disposed between two adjacent color films. An insulation layer  24  and a transparent conducting layer  25  are installed on the color resist layer. 
         [0043]    An isolation layer is disposed on the transparent conducting layer  25 . The isolation layer comprises a plurality of isolators  31 . 
         [0044]    The second substrate  10  and the first substrate  20  are disposed opposite to each other. The second substrate  10  comprises a second base substrate  11 , and a switch array layer on the second base substrate  11 . The switch array layer comprises a plurality of thin film transistors (TFTs). 
         [0045]    The second substrate  10  further comprises data lines and scan lines, and a plurality of pixel units defined by the data lines and scan lines. The pixel units comprise red, green and blue pixel units.  FIG. 2  shows the pixel units comprising red pixels  41 , green pixels  42  and blue pixels  43 . 
         [0046]    As shown in  FIG. 1 , the liquid crystal layer comprises one or more red liquid crystal unit  101 , green liquid crystal unit  102  and blue liquid crystal unit  103 . One of the isolators  31  is disposed between two adjacent liquid crystal units. For example, an isolator  31  is disposed between the red liquid crystal unit  101  and green liquid crystal unit  102 . The isolators  31  are used to prevent crosstalk of two adjacent liquid crystal units when beams of a backlight source reach them. 
         [0047]    Liquid crystal molecules  30  of the red liquid crystal unit  101  are mixed with red QRs  32 . Liquid crystal molecules  30  of the green liquid crystal unit  102  are mixed with green QRs  33 . Liquid crystal molecules  30  of the blue liquid crystal unit  103  are not mixed with QRs of any color. 
         [0048]    The position of the red liquid crystal unit  101  corresponds to that of the red pixels  41  or the red color film. The position of the green liquid crystal unit  102  corresponds to that of the green pixels  42 . The position of the blue liquid crystal unit  103  corresponds to that of the blue pixels  43 . 
         [0049]    The red QRs, green QRs, and the liquid crystal molecules all have long axes, which are all in the same direction. Due to the influence of anchoring force, the long axes of the QRs will always align along the long axes of the liquid crystal molecules. The LCD panel of the present invention needs a blue backlight source. 
         [0050]    Of course, it is fine not to dispose a color resist film on top of the first substrate  20 . After the blue backlight activates the red and green QRs mixed in the liquid crystal layer, the red and green QRs generate red and green light. Along with the blue backlight, they form the light source needed by the LCD panel to display. 
         [0051]    The method of forming the LCD panel of the present invention comprises the following steps: 
         [0052]    S 101 : make use of the lithography process to form isolators on the first substrate. 
         [0053]    First, form black matrixes, color resist films and a transparent conducting layer on the first base substrate  21 . Form the isolators after the transparent conducting layer is completed. On the transparent conducting layer, spacers can also be installed which can be supportive when the panel is pressured. The isolators  31  can be formed with the same materials as the spacers. 
         [0054]    S 102 : By means of ink-jetting, drip the liquid crystal molecules mixed with the red QRs  32  to the position corresponding to that of the red pixels  41 ; drip the liquid crystal molecules mixed with the green QRs  33  to the position corresponding to that of the green pixels  42 ; drip pure liquid crystal molecules to the position corresponding to that of the blue pixels  43 . 
         [0055]    The LCD panel of the present embodiment is a twist nematic (TN) LCD panel. 
         [0056]    Please refer to  FIG. 1 . When scan signals are at a low voltage level, the TFTs are closed. Without an electric field, the QRs, along with the liquid crystal molecules, are aligned in a manner twisted to a certain extent, with the QRs spanning from the second substrate  10  to the side of the first substrate  20 . When the backlight source passes through the second polarizer  12  and shines on the liquid crystal layer, it is transformed from a non-polarized light to a polarized light, so that the polarization direction of the second polarizer  12  is the same as the long axes of the QRs close to the side of the second substrate  10 . At this point, the red QRs  32  and green QRs  33  are most capable of light absorption and emission. Activated by the polarized light, the red QRs  32  and green QRs  33  emitted polarized red light and green light respectively. When the red light and green light reach the first polarizer  22 , their polarization direction has been gradually turned, along with the liquid crystal molecules, to the polarization direction of the first polarizer  22 . It is when the LCD panel is the brightest (the first brightness state). The present invention adds QRs and makes use of the optical anisotropy of the QRs, so that the LCD panel is brighter than the TN display model of current LCD panels. 
         [0057]    When TFTs are not fully opened, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second substrate and the long axes of the QRs close to the side of the second substrate form a set angle. At this point, the red QRs  32  and green QRs  33  are not very capable of light absorption and emission. Activated by the polarized light, the red QRs and green QRs emit polarized red and green light respectively. When the red and green light reach the first polarizer, the polarization direction has been gradually turned with the liquid crystal molecules, so it forms a set angle with the polarization direction of the first polarizer. It is when the LCD is in a brighter state (a second brightness state). In this state, because of the QRs, the LCD panel is brighter than when there were only liquid crystal molecules. 
         [0058]    Please refer to  FIG. 3 . When scan signals are at a high voltage level, the TFTs are fully opened. Under the effect of the electric field, the liquid crystal molecules turn to the position as shown in  FIG. 3 . Meanwhile, the QRs, along with the liquid crystal molecules, turn to be lined perpendicularly to the first substrate  20 . When the backlight source passes through the second polarizer  12  and shines on the liquid crystal layer, because the polarization direction of the light is perpendicular to the direction of the long axes of the liquid crystal molecules and the QRs, light absorption and emission of the red QRs  32  and green QRs  33  are very weak. Therefore, the QRs almost have no influence on the polarization status of the light. When the light passes through the first polarizer  22 , the polarization direction of the light is perpendicular to that of the first polarizer  22 . It is when the liquid crystal layer is in its darkest state (the third brightness state). 
         [0059]    By adding the QRs, part of the polarized light changes its direction from perpendicular to parallel, which enhanced the transmittance of the polarizers effectively. In addition, QRs of a color identical to pixels were added to the position corresponding to the specific pixels, effectively enhancing the color saturation and gamut, making the color of the LCD panel more vivid. 
         [0060]    Please refer to  FIG. 4 .  FIG. 4  is a structure diagram of a LCD panel of a second embodiment of the present invention. 
         [0061]    The LCD panel of the present invention comprises a first substrate  20 , a second substrate  10 , and a liquid crystal layer, disposed between the first substrate  20  and the second substrate  10 . The first substrate  20 , e.g. is a color film substrate, and the second substrate  10 , e.g. is an array substrate. The first substrate  20  comprises a first base substrate  21 , and a first polarizer  22  disposed on an external side of the first substrate. A color resist layer can further be disposed on the first base substrate. The color resist layer comprises a red color film  26 , green color film  27  and blue color film  28 . A black matrix  23  can be disposed between two adjacent color films. An insulation layer  24  and a transparent conducting layer  25  are installed on the color resist layer. 
         [0062]    An isolation layer is disposed on the transparent conducting layer  25 . The isolation layer comprises a plurality of isolators  31 . 
         [0063]    The second substrate  10  and the first substrate  20  are disposed opposite to each other. The second substrate  10  comprises a second base substrate  11 , and a switch array layer on the second base substrate  11 . The switch array layer comprises a plurality of thin film transistors (TFTs). 
         [0064]    The second substrate  10  further comprises data lines and scan lines, and a plurality of pixel units defined by the data lines and scan lines. The pixel units comprise red, green and blue pixel units.  FIG. 2  shows the pixel units comprising red pixels  41 , green pixels  42  and blue pixels  43 . 
         [0065]    As shown in  FIG. 4 , the liquid crystal layer comprises one or more red liquid crystal unit  101 , green liquid crystal unit  102  and blue liquid crystal unit  201 . One of the isolators  31  is disposed between two adjacent liquid crystal units. For example, an isolator  31  is disposed between the red liquid crystal unit  101  and green liquid crystal unit  102 . The isolators  31  are used to prevent crosstalk of two adjacent liquid crystal units when beams of a backlight source reach them. 
         [0066]    Liquid crystal molecules  30  of the red liquid crystal unit  101  are mixed with red QRs  32 . Liquid crystal molecules  30  of the green liquid crystal unit  102  are mixed with green QRs  33 . Liquid crystal molecules  30  of the blue liquid crystal unit  201  are mixed with blue QRs  34 . 
         [0067]    The position of the red liquid crystal unit  101  corresponds to that of the red pixels  41  or the red color film. The position of the green liquid crystal unit  102  corresponds to that of the green pixels  42  or the green color film. The position of the blue liquid crystal unit  201  corresponds to that of the blue pixels  43  or the blue color film. 
         [0068]    The red QRs, green QRs, blue QRs and the liquid crystal molecules all have long axes, which are all in the same direction. Due to the influence of anchoring force, the long axes of the QRs will always align along the long axes of the liquid crystal molecules. The LCD panel of the present invention needs a backlight source emitting white light. 
         [0069]    Of course, it is fine not to dispose a color resist film on top of the first substrate  20 . After the white backlight activates the red, green and blue QRs mixed in the liquid crystal layer, the red and green QRs generate red, green, and blue light. Along with the white backlight, they form the light source needed by the LCD panel to display. 
         [0070]    The method of forming the LCD panel of the present invention comprises the following steps: 
         [0071]    S 101 : make use of the lithography process to form isolators on the first substrate. 
         [0072]    First, form black matrixes, color resist films and a transparent conducting layer on the first base substrate  21 . Form the isolators after the transparent conducting layer is completed. On the transparent conducting layer, spacers can also be installed which can be supportive when the panel is pressured. The isolators  31  can be formed with the same materials as the spacers. 
         [0073]    S 102 : By means of ink-jetting, drip the liquid crystal molecules mixed with the red QRs  32  to the position corresponding to that of the red pixels  41 ; drip the liquid crystal molecules mixed with the green QRs  33  to the position corresponding to that of the green pixels  42 ; drip liquid crystal molecules mixed with the blue QRs  34  to the position corresponding to that of the blue pixels  43 . 
         [0074]    The LCD panel of the present embodiment is a twist nematic (TN) LCD panel. 
         [0075]    Please refer to  FIG. 4 . When scan signals are at a low voltage level, the TFTs are closed. Without an electric field, the QRs, along with the liquid crystal molecules, are aligned in a manner twisted to a certain extent, with the QRs spanning from the second substrate  10  to the side of the first substrate  20 . When the backlight source passes through the second polarizer  12  and shines on the liquid crystal layer, it is transformed from a non-polarized light to a polarized light, so that the polarization direction of the second polarizer  12  is the same as the long axes of the QRs close to the side of the second substrate  10 . At this point, the red QRs  32 , green QRs  33 , and blue QRs  34  are most capable of light absorption and emission. Activated by the polarized light, the red QRs  32 , green QRs  33 , and blue QRs  34  emitted polarized red light, green light, and blue light respectively. When the red light and green light reach the first polarizer  22 , their polarization direction has been gradually turned, along with the liquid crystal molecules, to the polarization direction of the first polarizer  22 . It is when the LCD panel is the brightest (the first brightness state). The present invention adds QRs and makes use of the optical anisotropy of the QRs, so that the LCD panel is brighter than the TN display model of current LCD panels. 
         [0076]    When TFTs are not fully opened, the QRs, along with the liquid crystal molecules, align in a twisted manner spanning from the second substrate to the side of the first substrate. Under the light of the backlight source, the polarization direction of the second substrate and the long axes of the QRs close to the side of the second substrate form a set angle. At this point, the red QRs  32 , green QRs  33  and blue QRs  34  are not very capable of light absorption and emission. Activated by the polarized light, the red QRs, green QRs, and blue QRs emit polarized red, green, blue light, respectively. When the red, green, and blue light reach the first polarizer, the polarization direction has been gradually turned with the liquid crystal molecules, so it forms a set angle with the polarization direction of the first polarizer. It is when the LCD is in a brighter state (a second brightness state). In this state, because of the QRs, the LCD panel is brighter than when there were only liquid crystal molecules. 
         [0077]    Please refer to  FIG. 5 . When scan signals are at a high voltage level, the TFTs are fully opened. Under the effect of the electric field, the liquid crystal molecules turn to the position as shown in  FIG. 5 , i.e., the liquid crystal molecules align in a vertical direction. Meanwhile, the QRs, along with the liquid crystal molecules, turn to be lined perpendicularly to the first substrate  20  or the second substrate  10 . When the backlight source passes through the second polarizer  12  and shines on the liquid crystal layer, because the polarization direction of the light is perpendicular to the direction of the long axes of the liquid crystal molecules and the QRs, light absorption and emission of the red QRs  32 , green QRs  33 , and blue QRs  34  are very weak. Therefore, the QRs almost have no influence on the polarization status of the light. When the light passes through the first polarizer  22 , the polarization direction of the light is perpendicular to that of the first polarizer  22 . It is when the liquid crystal layer is in its darkest state (the third brightness state). The first brightness state is brighter than the second brightness state, and the second brightness state is brighter than the third brightness state. 
         [0078]    By adding the QRs, part of the polarized light changes its direction from perpendicular to parallel, which enhanced the transmittance of the polarizers effectively. In addition, QRs of a color identical to pixels were added to the position corresponding to the specific pixels, effectively enhancing the color saturation and gamut, making the color of the LCD panel more vivid. 
         [0079]    The present invention provides LCD panels, and a method of forming the same. It mixes QRs of a color identical to pixels with liquid crystal molecules at the position corresponding to the specific pixels, so to enhance the transmittance of the polarizers and the color gamut of the LCD panel. Furthermore, it can lower the production cost for it does not need to produce extension thin film and introduce extension technology.
