The disclosure relates to a display technical field, and more particularly to a liquid crystal display panel and a pixel structure thereof and further particularly to a liquid crystal display device including the liquid crystal display panel.
Liquid crystal display (LCD) is a flat thin display device consisting of a certain number of color or black and white pixels, and placed in front of the light source or the reflector. LCD has the characteristics such as low power consumption, high quality, small size, light weight, so LCD has become the mainstream display device. The liquid crystal display device includes a backlight unit and a liquid crystal display panel. The principle of color for a liquid crystal display is generally as follows: the white light from the backlight unit is controlled by the switch of the liquid crystal display panel, and the light intensity of different pixels is controlled, then the color filter is performed by color resist layers having red (R), green (G) and blue (B) to obtain different intensities of red, green and blue light. That is, through mixing the primary colors of red, green and blue to get the color image.
As shown in
A technical problem to be solved by the disclosure is to provide a liquid crystal display panel and a pixel structure thereof, and the locus of the color coordinate of the white point of the display panel is modulated, so the problem of the bluish image in low grayscale of the display panel could be solved.
To achieve the above object, according to one aspect, the embodiment of the disclosure provides a pixel structure of a liquid crystal display panel including a red sub-pixel, a green sub-pixel, and a blue subpixel sequentially arranged, wherein an area of the green sub-pixel is larger than an area of the red sub-pixel, and an area of the blue subpixel is smaller than the area of the red sub-pixel.
In one embodiment, a ratio of the area of the green sub-pixel to the area of the red sub-pixel is 1.2˜1.5.
In one embodiment, a ratio of the area of the blue sub-pixel to the area of the red sub-pixel is 0.5˜0.8.
In one embodiment, a ratio of the area of the red sub-pixel to the area of the green sub-pixel to the area of the blue sub-pixel is 1:1.2:0.8.
The disclosure further provides a liquid crystal display panel including a plurality of pixel structures arranged in matrix, wherein each of the pixel structures is the above-mentioned pixel structure.
In one embodiment, the liquid crystal display panel includes a bottom polarizer, a thin film transistor array substrate, a liquid crystal layer, a color filter substrate, and a top polarizer sequentially disposed.
The disclosure further provides a liquid crystal display device including a liquid crystal display panel and a backlight module, the liquid crystal display panel is disposed opposite to the backlight module, the backlight module is configured to provide a display light source to the liquid crystal display panel, and the liquid crystal display panel is configured to display an image, wherein the liquid crystal display panel is the above-mentioned liquid crystal display panel.
In the liquid crystal display panel and the pixel structure thereof provided by the embodiment of the disclosure, the locus of the color coordinate of the white point of the display panel is modulated by adjusting the area ratio of each color sub-pixel. Specifically, based on the red sub-pixel, the area of the green sub-pixel is arranged to be larger than the area of the red sub-pixel, the area of the blue sub-pixel is arranged to be smaller than the area of the red sub-pixel, so the problem of the bluish image in low grayscale of the display panel could be solved and the display quality could be increased. In addition, the above-mentioned pixel structure could also improve the overall light transmittance of the liquid crystal display panel.
