A glasses-free 3D display system and method with low crosstalk and controllable viewing angle

Abstract

The invention discloses a low-crosstalk visual-angle-controllable naked-eye 3D display system and a method, wherein the display system comprises the following elements arranged successively along the travel direction of the light: a backlight source, a Fresnel lens array and a liquid crystal panel. The light field produced by the backlight source forms an observation image at the visual area through the Fresnel lens array and the liquid crystal panel. The light out-coming face of the liquid crystal panel is provided with a transparent filling layer. The filling layer fills the frosted structure of the light out-coming face of the liquid crystal panel so that the light rays shoots directly on the light out-coming face of the liquid crystal panel. According to the invention, the naked-eye 3D display system and the method, through the filling of the frosted structure of the liquid crystal panel face, enables that the light field shot out by the liquid crystal panel does not scatter in all directions but instead shoots out directly from the liquid crystal panel. The invention also restricts the watching angle through an anti-glare film. The visual angle of the anti-glare film can be designed according to the actual requirements so as to reduce the signal crosstalk rate of the naked-eye 3D display system and to control the angle thereof, therefore, increasing the watching effect.

Description

technical field [0001] The invention belongs to the field of naked-eye 3D display, and more particularly relates to a naked-eye 3D display system and method with low crosstalk and controllable viewing angle. Background technique [0002] For the naked-eye 3D display system, due to the air and the scattering of light by the scattering layer structure of the liquid crystal panel, there will be a certain crosstalk rate problem. In addition, the best viewing positions of the system are only distributed in a small area, and it is difficult to limit the viewing angle. If you watch 3D images outside the best viewing positions, the brightness of the image will be significantly reduced, and the crosstalk rate is high, and there will be ghosting phenomenon, causing visual discomfort. [0003] For 3D display devices, crosstalk refers to the signal (light) that should enter the left eye enters the right eye when the signal (light) from the left and right eyes is sent by the 3D display ...
