The invention discloses a color filter substrate. The color filter substrate comprises a substrate body, a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel, and the red sub-pixel, the green sub-pixel, the blue sub-pixel and the white sub-pixel are arranged on the substrate body; the red sub-pixel, the green sub-pixel and the blue sub-pixel are utilized for displaying a first white picture, the white sub-pixel is utilized for displaying the second white picture, and a white chromaticity coordinate of the first white picture is in accordance with that of the second white picture. According to the color filter substrate, the white chromaticity coordinate of the first white picture displayed by the white sub-pixel of an RGBW display panel can be in accordance with that of the white picture displayed by the red sub-pixel, the green sub-pixel and the blue sub-pixel of the RGBW display panel, therefore, the color temperature drifting degree of the white picture displayed by the RGBW display panel is in accordance with that of a white picture displayed by an original RGB display panel, and the display effect of the RGBW display panel can be improved conveniently.
Description
technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a color filter substrate, a liquid crystal panel and a liquid crystal display. Background technique [0002] At present, in most display devices having, for example, liquid crystal panels, a pixel is composed of a red (R) sub-pixel, a green (G) sub-pixel and a blue (B) sub-pixel. By controlling the grayscale data of each sub-pixel, the colors required to be displayed by the display panel are mixed to display a color image. [0003] With the development of information technology, various requirements for display panels are also increasing, and high transmittance, low power consumption, and good image quality have become people's requirements for display panels. The transmittance and mixing efficiency of the existing RGB three-primary-color mixed light display method are relatively low, resulting in high power consumption of the display panel, which rest...
