Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] In the prior art, each pixel of a liquid crystal display panel includes three sub-pixels, which are red sub-pixels, green sub-pixels and blue sub-pixels respectively, and the aspect ratio of each sub-pixel is 3:1, and when displaying , each pixel acts as a display unit, and the brightness center is located at the physical center of each pixel. Such as figure 1 As shown, if the width of each sub-pixel is L and the length is 3L, then in a 12L×12L area, t...

Abstract

The embodiment of the invention provides a liquid crystal display panel, a display device and a brightness conversion method of the display device, relates to the technical field of display, and can finish high-resolution display under the condition of lower actual resolution. A liquid crystal display panel comprises a plurality of repeating units arranged in an array mode. The repeating unit comprises four color sub-pixels and four white sub-pixels, wherein the four color sub-pixels comprise two first color sub-pixels, one second color sub-pixel and one third color sub-pixel, the four color sub-pixels are arranged in a 2*2 manner, and the two first color sub-pixels are arranged diagonally, wherein the four white sub-pixels are arranged in a 2*2 mode, the first row of white sub-pixels arearranged between the first row of color sub-pixels and the second row of color sub-pixels, the second row of white sub-pixels are arranged on the side, away from the first row of white sub-pixels, ofthe second row of color sub-pixels, and the white sub-pixels are overlapped with half of the side length of the adjacent color sub-pixels, wherein the first color, the second color and the third colorare three primary colors.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel, a display device and a brightness conversion method thereof. Background technique [0002] Dual Cell is a new breakthrough in TFT-LCD technology. By adopting million-level pixel partition technology and fine brightness adjustment in the sub-millimeter range, it can achieve ultra-high dynamic contrast ratio of 100,000 levels. [0003] Dual Cell consists of a liquid crystal display panel (Main Cell Panel) and a light control panel (Sub Cell Panel). Among them, the light control panel is used as the backlight of the liquid crystal display panel, and its resolution is 1920×1080; the liquid crystal display panel is used for image display, and its resolution is 3840×2160. [0004] Due to the high resolution and insufficient process precision, deviations are prone to occur when the liquid crystal display panel and the light control panel are laminated, ...
