Title:
LIGHT CONTROL DEVICE AND MANUFACTURING METHOD THEREFOR, AND 3D PRINTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/184284
Kind Code:
A1
Abstract:
A light control device and a manufacturing method therefor, and a 3D printing system. The light control device comprises: a first polarizer (21), an array substrate, liquid crystal (24), an opposed substrate (25), and a second polarizer (26) which are sequentially arranged; and the array substrate comprises: a substrate (22), and a pixel array (23) and a black matrix (27) which are formed on the substrate (22), the black matrix (27) at least forming at an area corresponding to a thin film transistor (231) of the pixel array (23). The light control device is used for 3D printing adopting curing molding in a light curing liquid material selection area. The light control device can accurately control an area irradiated by light by applying a principle of liquid crystal display, thereby accurately curing a light curing liquid resin selection area.
