Liquid crystal display device

Abstract

The invention provides a liquid crystal display device. The liquid crystal display device comprises a liquid crystal layer, the liquid crystal layer is divided into a plurality of pixels, and the multiple pixels are provided with a plurality of electrodes applying voltages to the liquid crystal layer. Each pixel of the multiple pixels comprises a first sub-pixel and a second sub-pixel; when each pixel of the multiple pixels is at the displaying gray level gk, the voltages applied to the liquid crystal layer by all the pixels of the first sub-pixels and the second sub-pixels are V1 (gk) and V2 (gk), and it is assumed that deltaV12(gk)=V1(gk)-V2(gk), wherein the gk is larger than or equal to 0 and smaller than or equal to n, the gk and the n are integers of 0 or above, and the n shows the gray level with the highest luminance; when the displaying gray level gk is smaller than a preset gray level gs, it is assumed that the deltaV12(gk) is larger than 0 volt, and meets the relationship that the deltaV12(gk) is larger than deltaV12(gk+1); when the displaying gray level gk is equal to or larger than the preset gray level gs, the deltaV12(gk) is smaller than 0 volt, and meets the relationship that the deltaV12(gk) is smaller than or equal to the deltaV12(gk+1).

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a technology for improving the gamma characteristics of the liquid crystal display device at different viewing angles. Background technique [0002] Liquid crystal display devices are flat-panel display devices that have advantages such as high resolution, thin shape, light weight, and low power consumption. In recent years, with the improvement of display performance, improvement of production capacity, and improvement of price competitiveness with other display devices , the market scale is expanding rapidly. [0003] In the conventional liquid crystal display device of general twisted nematic mode (TN mode), the major axes of the liquid crystal molecules having positive dielectric constant anisotropy can be aligned approximately parallel to the substrate surface, and the alignment treatment is performed to make the liquid crystal molecules The long axis of the liquid crystal...
