Title:
TOUCH POLARIZING STRUCTURE AND FLEXIBLE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/179049
Kind Code:
A1
Abstract:
A touch polarizing structure and a flexible display device. The touch polarizing structure comprises a touch layer (10) and a circular polarizer (20); the touch layer (10) comprises a substrate (11) and a touch electrode layer (12) provided at one side of the substrate (11); the circular polarizer (20) comprises a linear polarizing layer (21) and a quarter-wave retarder (22) or a linear polarizing layer (21), a half-wave retarder (24), and a quarter-wave retarder (22) which are sequentially provided at the side of the substrate (11) away from the touch electrode layer (12) along a direction away from the substrate (11); the linear polarizing layer (21), the quarter-wave retarder (22), and the half-wave retarder (24) each comprise an alignment layer and a liquid crystal layer. The touch polarizing structure is provided on a display surface of a flexible display panel and the touch polarizing structure is thin in thickness, so that the overall thickness of the flexible display device is greatly reduced while the functions of reducing external reflected light and implementing touch display are achieved, the stress applied on the flexible display device during bending can be effectively reduced, and the product quality is improved.
