Title:
LIQUID CRYSTAL PROJECTION LAYER FOR GLASS, GLASS, VEHICLE, AND GLASS MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/116958
Kind Code:
A1
Abstract:
A liquid crystal projection layer for a glass, a glass, a vehicle, and a glass manufacturing method. The glass (100) comprises a first glass (11) and a liquid crystal projection layer. The first glass (11) comprises a first surface (111) and a second surface (112) which are opposite to each other. The liquid crystal projection layer comprises a transparent projection layer (20) which is disposed on one side of the first glass (11) close to the second surface (112) and is configured to display a projection image received from a projector (70); and a liquid crystal module (30) which is disposed between the first glass (11) and the transparent projection layer (20) and is configured to switch between a transparent mode and a privacy mode. In the transparent mode, the liquid crystal module (30) allows the projection image displayed on the transparent projection layer (20) to be transferred to the first glass (11). In the privacy mode, the liquid crystal module (30) prevents the projection image displayed on the transparent projection layer (20) from being transferred to the first glass (11). Therefore, the liquid crystal projection layer for the glass can be kept transparent during normal operation of the vehicle and achieves privacy protection when transparent projection display is performed.
