Abstract

The invention discloses a naked-eye three-dimensional display device. The naked-eye three-dimensional display device includes a backlight module, a liquid crystal panel, and a lens assembly stacked in sequence, and the lens assembly includes a number of lens units arranged in a predetermined manner, wherein in the arrangement direction of the lens units, the backlight module The full width at half maximum of the light intensity versus angle variation curve of the output light is less than or equal to 10°. The present invention can eliminate the existence of the sub-viewpoint, effectively increase the brightness of the main viewpoint during 3D display, reduce the image crosstalk between adjacent pixels, and can significantly reduce the thickness of the display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a naked-eye stereoscopic display device. Background technique [0002] 3D display technology has become an inevitable development trend of future display technology because it can reproduce the cognitive methods familiar to humans in nature. Among them, naked-eye 3D technology is very popular because it gets rid of complicated auxiliary equipment. [0003] There are various ways to realize naked-eye 3D display, including grating, lens technology, etc. Among them, grating technology has better stereoscopic display effect because it can effectively block image crosstalk between different viewpoints, but it also faces the regret of loss of brightness. In the current environment where 3D display technology has not completely replaced 2D display, the glasses-free 3D solution based on lenses has become a better technical solution because it can minimize the impact on the brightness of...
