Abstract

The invention discloses a 3D (three-dimensional) display device and system, and relates to the technical field of 3D display. A liquid crystal display comprises a display panel, wherein the display panel comprises an array substrate, a color-film substrate, and liquid crystals, the color-film substrate is opposite to the array substrate, and the liquid crystals are filled between the array substrate and the color-film substrate. The 3D display device controls liquid-crystal molecules to rotate by virtue of a driving voltage; in a display period of a 3D image, the 3D display device drives the liquid crystal molecules to be deflected to a first angle during left-eye image display so that the polarization direction of linear polarized light emitted from the array substrate rotates to be the first angle, and also drives the liquid crystal molecules to be deflected to a second angle during right-eye image display so that the polarization direction of linear polarized light emitted from the array substrate rotates to be the second angle, and a differential value is configured between the first angle and the second angle. The 3D display device and system provided by the invention have the advantages of simple production process, low process precision requirement, reduced cost and improved display resolution.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to a 3D display device and system. Background technique [0002] Three-dimensional (3D) liquid crystal display has become a trend in the field of display. The basic principle of 3D liquid crystal display is that parallax produces stereo, even if people's left eye sees the image of the left eye, and the right eye sees the image of the right eye. The left and right eye images are a pair of stereoscopic images with parallax. [0003] The 3D liquid crystal display technology based on polarized glasses is a more commonly used 3D liquid crystal display technology. Two left and right images are projected by the display, and the user uses polarized glasses matched with the display to distribute the left and right images to the left and right eyes respectively. Polarized glasses use lenses with different polarization directions to make the light emitted by the display produce di...
