Abstract

The invention discloses a 2D-3D display switching optical module, a preparation method thereof and a display device. The preparation method of the 2D-3D display switching optical module comprises thefollowing steps: forming a cylindrical lens base material on a first substrate; embossing the cylindrical lens base material by an embossing mold to form a plurality of cylindrical lens structures which are parallel; releasing the embossing mold from the cylindrical lens structures; coating the side, which is away from the first substrate, of each cylindrical lens structure with a first alignmentfilm; and carrying out frictional alignment on the first alignment film, wherein the initial position of frictional alignment and the mold releasing starting position are positioned on different sidesof the first substrate. The invention provides the 2D-3D display switching optical module, the preparation method thereof and the display device, and thus, the problems that in a frictional alignmentprocess of the alignment film, edges of cylindrical lenses hook cloth, and thus, the performance of the alignment films is poor are solved.

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. 3D display has entered the user's field of vision. Compared with 2D display, 3D display has a better sense of space, giving people an immersive feeling. 3D display is divided into glasses type 3D display and naked eye type 3D display. Glasses-type 3D display technology, due to the need to wear special glasses, is not as good as naked-eye 3D display technology in terms of both sensitivity and convenience. Glasses-free 3D display technology has become a hot spot in 3D display technology research. [0003] Among the naked-eye 3D display technologies, the most common is the liquid crystal lenticular lens film stereoscopic display technology that utilizes the se...
