Grating manufacturing method and device

Abstract

The invention provides a grating manufacturing method and device, and relates to the technical field of grating manufacturing. The grating manufacturing method comprises the following steps: making a mold with a lug according to a carving parameter; making a membrane material according to the mold, wherein the membrane material comprises a first area provided with a groove and a second area with a flat surface; performing first directional friction operation on the surface provided with the groove of the membrane material; coating a liquid crystal directional layer with a molten liquid crystal, so that the liquid crystal directional layer comprises a third area with the liquid crystal and a fourth area without the liquid crystal, the third area corresponds to the first area, and the fourth area corresponds to the second area; attaching the membrane material to the liquid crystal directional layer, so that the first area is coincided with the third area and the second area is coincided with the fourth area, and exposing and curing to obtain a grating. The area with the liquid crystal and the area without the liquid crystal are formed respectively in the grating, so that the problems of complicated electrode design and high manufacturing cost due to coexistence of 2D display and 3D display in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of grating preparation, in particular to a grating preparation method and device. Background technique [0002] With the continuous development of economy and technology, in order to improve the three-dimensional effect of the playing picture, 3D display technology has been continuously developed. The early 3D display technology mainly achieved the purpose of 3D display of content by wearing additional devices such as specially treated glasses and helmets. [0003] The above-mentioned technology for realizing 3D display through an additional device has the disadvantage of low display quality of 2D images. In view of this, in the prior art, a scheme for switching between 2D / 3D images is proposed, mainly by controlling the electrodes on both sides of the liquid crystal to realize whether the liquid crystal molecules are deflected, thereby realizing the switching between 2D / 3D display. However, this method ha...
