Thin film transistor (TFT) array substrate, liquid crystal display, driving method thereof and three-dimensional (3D) display system

Abstract

The invention discloses a thin film transistor (TFT) array substrate, a liquid crystal display, a driving method thereof and a three-dimensional (3D) display system. An effective display pixel electrode and an active light blocking electrode are respectively arranged at an upper area and a lower area in each sub-pixel unit, and different grid electrode signal lines and data lines are used respectively for providing electric signals for the effective display pixel electrodes and the active light blocking electrodes. In a two-dimensional (2D) display mode, the areas where the active light blocking electrodes are located display images normally, and normal display cannot be influenced; in 3D display mode, the areas where the active light blocking electrodes are located form dark fields, and crosstalk light between adjacent pixels in the vertical direction can be reduced so as to improve a vertical visual angle of 3D display. In the 3D display mode, public electrode signals are exerted on the active light blocking electrodes, no voltage difference between the active light blocking electrodes and public electrodes is guaranteed when a TFT switch connected with the active light blocking electrodes leaks electricity, the phenomenon that brightening occur at the areas where the active light blocking electrodes are located is prevented, and the problem of crosstalk is avoided.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a TFT array substrate, a liquid crystal screen, a driving method thereof and a 3D display system. Background technique [0002] In daily life, people use two eyes to observe the external scene with a three-dimensional sense of space. Three-dimensional (3D) display technology uses the principle of binocular stereo vision to enable people to obtain a sense of three-dimensional space. The main principle is to make the viewer's left The eye and the right eye receive different images respectively, and the position difference caused by the interpupillary distance between the viewer's two eyes makes the two images with "binocular parallax" constitute a "stereoscopic image pair", while the "stereoscopic image "Right" makes the viewer feel three-dimensional after being analyzed and fused by the brain. [0003] Currently, there are two types of 3D display technologies: glasses-free and...

Problems solved by technology

[0005] Further, in order to improve the viewing angle of the polarized 3D display device in the vertical direction, such as figure 2 As shown, a light blocking strip (BS) is generally added on the PR film to prevent the crosstalk of the left and right eyes. However, the setting of the BS will reduce the aperture ratio of the 3D display device, and will generate moiré fringes in the 2D display mode, affecting normal display
