Problems solved by technology

In addition, the friction method is also limited to alignment on a plane. For curved substrates, it is difficult to achieve a consistent alignment effect with the friction method.
These are the disadvantages of the friction method, which is not conducive to the further development of the manufacture of liquid crystal optical components and restricts the upgrading of the industry

Abstract

The invention provides equipment and a method for manufacturing a liquid crystal optical element. The manufacturing equipment comprises a first transmitting device used for transmitting a substrate, a liquid crystal distribution device used for distributing liquid-state liquid crystal materials for the surface of the substrate, an electric field generating device used for generating an electric field so as to distribute directions for liquid crystal molecules in the liquid-state liquid crystal materials, and a curing device used for curing the liquid-state liquid crystal materials when the electric field generating device distributes directions for the liquid crystal molecules. Due to the mode, in the process of manufacturing the liquid crystal optical element, by performing non-contact direction distribution on the liquid crystal molecules by using the electric field, dust and static generated due to friction in a friction method can be effectively eliminated, and the finished product ratio and quality of the liquid crystal optical element are improved.

Description

【Technical field】 [0001] The invention relates to an optical element manufacturing equipment and a manufacturing method, in particular to a liquid crystal optical element manufacturing equipment and a manufacturing method. 【Background technique】 [0002] Liquid crystal optical elements are widely used in various display fields. Such as figure 1 as shown, figure 1 A liquid crystal birefringent grating applied in a 2D / 3D point-by-point switching stereoscopic display is shown. The liquid crystal birefringence grating includes a substrate 1 , a sub-mode grating 2 and a liquid crystal layer 3 sandwiched between the substrate 1 and the sub-mode grating 2 . In the above-mentioned liquid crystal birefringent grating and other liquid crystal optical elements, it is often necessary to align the liquid crystal molecules in the liquid crystal layer 3 so that the liquid crystal molecules are arranged in a predetermined direction as required. [0003] The current alignment technology ...
