Abstract

The invention discloses a 2D-3D display switching optical module, a preparation method thereof, and a display device, wherein, the preparation method of the 2D-3D display switching optical module includes: forming a cylindrical lens base material on a first substrate; The stamping mold embosses the cylindrical lens base material to form a plurality of cylindrical lens structures arranged in parallel; the imprinting mold is released from the plurality of the cylindrical lens structures; when the cylindrical lens structure is far away from the first Coating a first alignment film on one side of the substrate; performing rubbing alignment on the first alignment film; wherein, the starting position of rubbing alignment and the starting position of demoulding are located on different sides of the first substrate. The present invention provides a 2D-3D display switching optical module and its preparation method, and a display device to solve the problem of poor performance of the alignment film caused by the edge hooking of the cylindrical lens during the frictional alignment process of the alignment film.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a 2D-3D display switching optical module, a preparation method thereof, and a display device. Background technique [0002] With the development of electronic technology, 2D display has been difficult to meet people's needs, and 3D display has entered the user's field of vision. Compared with 2D display, 3D display has a better sense of space and gives people an immersive feeling. 3D display is divided into glasses-type 3D display and naked-eye 3D display. Glasses-based 3D display technology, because it needs to wear special glasses, is not as comfortable and convenient as naked-eye 3D display technology. Glasses-free 3D display technology has become a hotspot in 3D display technology research. [0003] Among naked-eye 3D display technologies, the liquid crystal lenticular lens film stereoscopic display technology that utilizes the depth perception formed by human binocular par...
