Title:
TOUCH COMPONENT AND PREPARATION METHOD THEREOF, TOUCH DISPLAY DEVICE, AND METHOD FOR PREVENTING MISTAKEN TOUCH CAUSED BY LIQUID
Document Type and Number:
WIPO Patent Application WO/2019/174371
Kind Code:
A1
Abstract:
A touch component and a preparation method thereof, a touch display device, and a method for preventing a mistaken touch caused by liquid. The touch component comprises: a touch electrode layer (100) configured to sense a touch area (TA) in a touch surface (TS); and an optical sensing film layer (200) stacked with the touch electrode layer (100), an optical receiving surface of the optical sensing film layer (200) facing towards the touch surface (TS). The touch component is simple in structure, and easy to implement. The optical sensing film layer (200) can recognize a water layer wetted area by sensing the intensity of a reflected light on the touch surface (TS), thereby effectively avoiding the mistaken touch of a water layer. Therefore, an unexpected screen touch feedback caused by the wetted area can be effectively avoided, and the effect of reducing water layer interference is good. The sensitivity of recognizing the mistaken touch caused by water layer wetting by utilizing the configuration is high, and the user experience is improved.
