Problems solved by technology

Moreover, traditional red (R), green (G), and blue (B) three-color liquid crystal displays set different driving voltages through driving integrated circuits to drive the liquid crystal display to display different gray scales. For red (R), green (G) ), blue (B) three colors, display different colors through different gray scales, so as to achieve the purpose of multi-color display, and to achieve 64-color display, at least 4 gray scale voltages need to be provided, and the power consumption is high. If the power consumption is reduced by reducing the frequency, there will be pixel leakage, which will cause abnormal display brightness of the middle gray scale, and then lead to abnormal image color

Abstract

The present invention provides a liquid crystal display panel and a display device. The liquid crystal display panel includes an array substrate, and the array substrate includes a plurality of pixels arranged in an array, and each pixel includes a first sub-pixel and a second sub-pixel arranged adjacently. A pixel, specifically, a first sub-pixel includes a first pixel electrode and a first electrode, and a second sub-pixel includes a second pixel electrode. Wherein, the area of ​​the second sub-pixel is larger than the area of ​​the first sub-pixel, and the area of ​​the second pixel electrode is larger than the area of ​​the first pixel electrode; the array substrate also includes an auxiliary electrode, at least part of which is overlapped with the first electrode to form a second pixel electrode. The first auxiliary capacitor of a sub-pixel, and the overlapping area of ​​the auxiliary electrode and the first electrode extends to the second sub-pixel in the same pixel, so that a part of the second sub-pixel can be used to increase the storage capacitance of the first sub-pixel, The storage capacitors of the first sub-pixel and the second sub-pixel are approximately equal.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to a liquid crystal display panel and a display device capable of realizing multi-color display under low power consumption. Background technique [0002] With the development of science and technology, display devices with display functions are used more and more widely. Among them, color display can provide users with more information and better visual experience than black and white display. Taking liquid crystal display as an example, The general color display uses color filters to form a color image, which is to use the principle of spatial color mixing to mix the three primary colors. [0003] Specifically, the imaging principle of the traditional liquid crystal display is to place the liquid crystal between the array substrate and the color filter substrate, driven by the electric field generated between the two electrodes, to cause the electric field effect of the liqui...
