Problems solved by technology

In order to control the crosstalk rate, usually the two viewing areas are separated and not interlaced as much as possible in space, so there is a certain dark area in the middle of the viewing area, and there is brightness unevenness
In addition, the backlight unit is usually driven with a fixed duty cycle, and the brightness is difficult to adjust
This limits the playback effect and viewing freedom of the directional backlight glasses-free 3D display when playing 2D images

Abstract

The invention provides an autostereoscopic display system with the brightness and uniformity adjustable and a control method of the autostereoscopic display system. In the system, scattering-transmission switchable scattering-transmission controllable membrane layers are arranged on the light-out surfaces of submodules of a backlight module, and the light-emitting angles of the backlight submodules can be adjusted by controlling the number of the membrane layers in scattering and transmission states; by controlling electrical parameters applied to the scattering-transmission controllable membrane layers, the transmission state and the scattering state of the module can be switched, or the scattering degree can be adjusted, and then the brightness uniformity and the brightness value are adjusted according to the requirements of a watcher.

Description

technical field [0001] The present invention relates to the field of naked-eye 3D display, and more particularly, to a naked-eye 3D display system with adjustable brightness and uniformity and a control method thereof. Background technique [0002] Glasses-free 3D display has incomparable advantages because it can provide images with depth information, which is closer to human eye habits than flat display, especially in medical, aerospace, military training and other fields, where depth information is particularly important. After recent years of development, naked-eye 3D display solutions based on cylindrical lens technology, grating technology and directional backlight technology have gradually appeared on the market. [0003] Among them, the basic principle of directional backlight technology is: corresponding to the left and right eyes of the viewer, there are two sets of independent backlight units, which cooperate with directional light guide plates or films, lenses, e...
