Example Embodiment
[0016] The invention includes a display panel (LCD or LED), a slit grating and multiple baffle structures. Wherein, the slit grating is a vertical flat plate installed in front of the display panel, and each grating unit is divided into a transparent part and an opaque part. For each eye, it blocks a part of the screen, so that the light of the pixel belonging to the left viewpoint all enters the field of view of the left eye, and the light of the pixel belonging to the right viewpoint all enters the field of view of the right eye. However, due to the shading effect of the opaque part of the slit grating, the displayed image is darker. According to the type of display panel, the multiple baffle structures, if applied to LCD type displays, can be placed in the liquid crystal layer in the display panel, specifically located on the black matrix between two pixels. It is smaller than the thickness of the liquid crystal layer; if it is applied to an LED display, it can be placed in...
