Abstract

The invention provides a preparation method and device for a liquid crystal lens. The method includes the steps of preparing a medium liquid crystal lens, wherein the optical grating angle of the medium liquid crystal lens is 0 degree; freezing the medium liquid crystal lens for a preset time to make liquid crystals converted from a liquid state to a solid state; cutting the medium liquid crystal lens after freezing to make the optical grating angle of the cut medium liquid crystal lens equal to a preset angle; sealing edges of the cut medium liquid crystal lens to form the liquid crystal lens. According to the preparation method and device for the liquid crystal lens, since the optical grating angle of the medium liquid crystal lens is 0 degree, during crystal filling for forming the medium liquid crystal lens, the phenomenon of undesirable filling due to the optical grating angle can be avoided, and the quality of the liquid crystal lens is improved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a method and device for preparing a liquid crystal lens. Background technique [0002] Early three-dimensional (3Dimensions, 3D) display technology enables people to enjoy stereoscopic images mainly through the assistance of auxiliary equipment such as 3D glasses and 3D helmets. With the continuous development of 3D display technology, self-stereoscopic display has gradually replaced traditional 3D display technology and has become the mainstream of current 3D display technology. The self-stereoscopic display mainly realizes the stereoscopic display of the picture by setting a grating on the display screen and based on the light-splitting principle of the grating. [0003] Current autostereoscopic display technologies mainly include: lenticular autostereoscopic display and slit grating autostereoscopic display. Among them, there are two types of lenticular gratings, one of whi...
