Problems solved by technology

Due to the existence of lens aberration, when viewed under an improper viewing angle (for example, the viewing angle is too large), the human eye will see the image information of pixels that should not be seen, which constitutes crosstalk and affects the 3D effect
Therefore, this design makes the 3D viewing angle narrow

Abstract

A 3D display device includes a display panel, a collimated backlight module, a lens array and a curved diffuser array. The lens array is arranged on the surface of the display panel. The curved diffuser array is disposed between the display panel and the lens array, and the two-dimensional image of the display panel is first diffused by the curved diffuser array, and then restored to a 3D scene by the lens array. The arrangement of the lens array, the curved diffuser array and the collimation backlight module can effectively improve the crosstalk phenomenon caused by the aberration of the lens array.

Description

[0001] 【Technical field】 [0002] The present invention relates to a liquid crystal display technology, in particular to a 3D display device capable of improving the crosstalk problem during 3D display. [0003] 【Background technique】 [0004] In order to satisfy the visual experience, the display technology has been developed to 3D display. Existing 3D display technologies can be roughly divided into glasses-type 3D display technologies (stereoscopic display) and naked-eye 3D display technologies (auto-stereoscopic display), wherein the advantage of the naked-eye 3D display technology is the convenience of not needing additional glasses. Currently, naked-eye 3D display technology can be realized by using a parallax barrier, a lenticular lens, or a directional backlight. [0005] Please refer to figure 1 and figure 2 as shown, figure 1 It is a structural schematic diagram of an existing lenticular lens 3D display device, figure 2 It is a schematic diagram of the operatio...
