a display device

Abstract

The invention belongs to the field of display technology, and in particular relates to a display device. The display device includes a display panel, the display panel includes a color filter substrate arranged oppositely, an array substrate and a liquid crystal layer arranged between them, the display panel is divided into a central area and a peripheral area surrounding the central area, The display panel is divided into a central area and a peripheral area surrounding the central area, and an additional polarizer is disposed between the array substrate and the liquid crystal layer corresponding to the peripheral area. The display device can effectively prevent light leakage in the peripheral area of ​​the display panel and improve the problem of light leakage in the peripheral area of ​​the display panel by providing an additional polarizer between the array substrate and the liquid crystal layer of the display panel and in the area corresponding to the peripheral area; Using a backlight with brighter brightness in the peripheral area than in the central area ensures the uniformity of the display image, and can also provide good overall image quality in the normally black mode.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display device. Background technique [0002] With the improvement of living standards, liquid crystal display devices (Liquid Crystal Display, LCD for short) have penetrated into people's daily life. The main components of the liquid crystal display device are a display panel (Panel) and a backlight source (BackLight Unit: BLU for short). [0003] Among them, the display panel usually includes a color filter substrate, an array substrate, and a liquid crystal layer disposed between them. The array substrate provides a driving electric field for driving the liquid crystal to deflect, and the deflection of the liquid crystal during the display process controls the light emitted by the backlight. Whether it is transmitted or not, the color filter substrate performs color processing on the transmitted light, so as to realize image display. [0004] According to the ...

Problems solved by technology

[0005] In liquid crystal display devices with horizontal alignment modes such as IPS and ADS, compared with liquid crystal display devices with vertical alignment modes such as VA and TN, due to the pressing effect of the frame between the backlight and the display panel on its surrounding area, it will cause The array substrate produces an optical path difference, which leads to light leakage of the display panel, and the local light leakage of the display panel in the normally black mode will lead to a decrease in the display performance of the display device

[0006] Therefore, how to solve the light leakage phenomenon caused by the optical path difference in the liquid crystal display device, and improve the black screen display, the problem of poor uniformity caused by light leakage in the peripheral area of ​​the display panel has become a technical problem to be solved urgently.
