Problems solved by technology

Regardless of the use of gratings, lenticular mirrors or prisms to control the transmission direction of the backlight, the resolution of the picture viewed by the user is only half of the resolution of the liquid crystal display panel, so the picture quality viewed by the user is not as good as very ideal

Abstract

The invention discloses a multi-vision angle LCD and driving method thereof, wherein, the multi-vision angle LCD allows different users to respectively watch different images from different view angles. The multi-vision angle LCD includes a liquid crystal display board, a first backlight module and a second backlight module. The first backlight module is provided beneath the liquid crystal display board, the second backlight module is provided between the first backlight module and the liquid crystal display board , wherein, the first backlight module provides a first surface light source, the second backlight module provides a second surface light source, an angle alpha is between the transfer direction of the first surface light source and the transfer direction of the second surface light source, and the angle alpha is from 6 degree to 176 degree. Therefore, when the different users watch different images displayed by the multi-vision angle LCD from different view angles, the resolution factor of these images is identical to that of the liquid crystal display board.

Description

technical field [0001] The invention relates to a liquid crystal display and a driving method thereof, in particular to a multi-view liquid crystal display (multi-view liquid crystal display) and a driving method thereof. Background technique [0002] With the advancement of display technology, people can make life more convenient with the help of displays. In order to achieve light and thin displays, Flat Panel Displays (FPDs) have become the mainstream at present, and liquid crystal displays (LCDs) Liquid Crystal Display, LCD) is the most popular. However, in order to allow users to see different display images when viewing the display from different angles, a multi-view liquid crystal display has been developed. [0003] Generally speaking, the multi-view liquid crystal display can be realized by means of light shielding by a barrier, refraction by a lenticular plate or refraction by a prism. Among them, the grating shading method is to arrange the grating outside the u...
