Abstract

The invention provides a three-dimensional display device. The three-dimensional display device comprises a first transparent conductive layer, a fresnel lens complementation layer and a second transparent conductive layer in an overlapped mode, the surface, facing the first transparent conductive layer, of the fresnel lens complementation layer is a concaved surface, the three-dimensional display device further comprises a liquid crystal layer, the space between the concaved surface and the first transparent conductive layer is filled with the liquid crystal layer, and the liquid crystal layer is a perpendicular orientation type liquid crystal layer. Through the arranged fresnel lens complementation layer, the arch height of a lens is reduced, response time of liquid crystal molecules in the liquid crystal layer is shortened, and the problem that the response time of the liquid crystal molecules is too long is effectively solved; by making the fresnel lens into the fresnel lens complementation layer in a reverse form, it is not needed to increase the refractive index of the fresnel lens complementation layer; a common fresnel lens material is adopted, the perpendicular orientation type liquid crystal layer is combined, in this way, the three-dimensional display device achieves switching between 2D and 3D, and then the research difficulty and cost of the fresnel lens material are lowered.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to a stereoscopic display device. Background technique [0002] With the rapid development of stereoscopic display technology, the demand for stereoscopic display equipment is also increasing. Among the many technologies for realizing 3D stereoscopic display, naked-eye stereoscopic display has the advantage of not requiring the viewer to wear glasses. It is very popular in the field of display. [0003] At present, the main way to realize naked-eye stereoscopic display technology is to set gratings in front of the display panel, and divide the pixel units of the display panel into odd-numbered and even-numbered columns of pixels in the horizontal direction, so as to provide the left and right eyes of the viewer with The two different images utilize the parallax effect of the viewer's left-eye image and right-eye image to form a depth of field, thereby producing a stereos...
