Display device for improving side light leakage and improving method thereof

Abstract

The invention provides a display device. The display device has a display region and a peripheral region located around the display region. The display device comprises an array substrate, an opposite substrate, a liquid crystal layer and an adjustable voltage signal wire. The liquid crystal layer is disposed between the array substrate and the opposite substrate; the array substrate comprises a plurality of pixel units arranged in the display region and a storage capacitor line arranged in the peripheral region, wherein each pixel unit comprises a storage capacitor and is electrically connected with the storage capacitor line; the adjustable voltage signal wire is disposed in the peripheral region and is arranged adjacent to the storage capacitor line, wherein the adjustable voltage signal wire is electrically connected with an adjustable voltage driving unit and is used for providing a voltage so as to generate a voltage difference with the storage capacitor line.

Description

technical field [0001] The present invention relates to a display device, in particular to a liquid crystal display device using adjustable voltage signal lines to improve side light leakage at large viewing angles. Background technique [0002] With the advancement of flat-panel display technology, optoelectronic products assisted by display panels make life more convenient. Therefore, among numerous consumer electronic products, thin and light, high-resolution flat panel display devices are still one of the most popular devices at present. Display panels with the advantages of thinness, power saving, and no radiation have been widely used in various consumer electronics fields, especially the presentation of multimedia images on display panels has become an indispensable part of mass life and entertainment. [0003] However, the current display panel has a defect of light leakage, which reduces the entertainment experience of the viewers, especially when watching a dark p...

AI Technical Summary

Problems solved by technology

In the peripheral area of ​​the known liquid crystal display panel, because the components and circuits arranged therein will form a stray electric field environment, the liquid crystal molecules at the junction of the peripheral area and the display area will be arranged uncontrollably, resulting in a predetermined dark state. In this state, the light is transmitted without being blocked and scattered in various angles. Some of the scattered light will be blocked by the black matrix on the opposite substrate, so that viewers in a small viewing angle will not notice it. However, the light that cannot be blocked by the black matrix will be clearly seen by the viewers in the large viewing angle range, especially the left and right sides, to see the side light leakage of the liquid crystal display panel.
