3d display device

Abstract

The invention provides a 3D display device, the 3D display device comprising: a display panel (30), and a metal wire grid polarizer (20) and a liquid crystal lens (10) arranged above the display panel (30), the liquid crystal lens (10) ) includes: a lens upper glass substrate (1), a lens lower glass substrate (5) opposite to the lens upper glass substrate (1), and a lens upper glass substrate (1) close to the lens lower glass substrate (5) A common electrode (2), a plurality of strip-shaped electrodes (4) arranged in parallel at intervals on the side of the lower glass substrate (5) near the lens upper glass substrate (1), and a plurality of strip electrodes (4) arranged between the lower lens glass substrate (5) and the upper lens substrate (1) The liquid crystal layer (3) between the glass substrates (1) on the lens, the metal wire grid polarizer (20) is arranged between the display panel (30) and a plurality of strip electrodes (4), the thickness of the polarizer can be reduced, Realize high-resolution glasses-free 3D image display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a 3D display device. Background technique [0002] As digital audio-visual technology enters the era of high-definition, three-dimensional (Three Dimension, 3D) stereoscopic display technology is increasingly concerned and favored by people. Among them, naked-eye 3D technology is very popular because it gets rid of complicated auxiliary equipment. There are various methods, such as gratings, liquid crystal lenses, etc.; the current mainstream naked-eye 3D display technology is mainly based on the spatial division of pixels, which will cause the display panel to display 3D images compared to two-dimensional (TwoDimension, 2D) image resolution. Attenuated by half, the perfect 3D effect cannot be presented. [0003] With the advancement of small-size panel display technology, the resolution of small-size display panels such as mobile phones and tablet computers is gr...
