Color film substrate, array substrate, display panel and display device

Abstract

The invention discloses a color film substrate, an array substrate, a display panel and a display device. The color brightness ratio of the display device can be improved, and the white balance effect is improved, so that the display quality of the display device is improved. The color film substrate comprises a plurality of first pixel units arranged and distributed in an array shape, the first pixel units comprise red sub-pixels, green sub-pixels and blue sub-pixels, the sub-pixels comprise colorful photoresistance of the corresponding colors and white photoresistance, a white chromaticity coordinate formed after color mixture of the red sub-pixels, the green sub-pixels and the blue sub-pixels equals a white chromaticity coordinate formed after color mixture of the red sub-pixels, the green sub-pixels and the blue sub-pixels with the area ratio of 1:1:1. Compensation can be carried out on the brightness difference caused by difference of light filtration effects of the colorful photoresistance by designing the white photoresistance of the corresponding area, and therefore the color brightness ratio of the display device can be improved, the white balance effect is improved, and the display quality of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate, an array substrate, a display panel and a display device. Background technique [0002] Among the flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, no radiation and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. The main structure of the TFT-LCD display panel includes an array substrate, a color filter substrate, and liquid crystals filled in a paired cell structure formed by the array substrate and the color filter substrate. [0003] In most current liquid crystal display devices, a pixel unit includes three sub-pixels of red (R), green (G), and blue (B), which can be controlled by adjusting the gray values ​​corresponding to the three color sub-pixels. For the color and brightness displayed by the pixel unit, ...

Problems solved by technology

[0005] However, although the transmittance of the pixel unit of the existing display panel is increased after the W sub-pixel is increased, the color brightness ratio is unbalanced, and the white balance effect is not good (white balance is the mixture of the three primary colors of red, green and blue in the display to generate white accuracy. degree), which affects the display quality of the display device
