Title:
IN-CELL TOUCH PANEL AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/173017
Kind Code:
A1
Abstract:
Provided are an in-cell touch panel and a manufacturing method. By designing a touch driving line into a segmented structure, when the distance value between the touch driving line and a touch sensing line is changed due to a pressing pressure of a user, the change in the distance value results in a change in the capacitance value between the touch driving line and the touch sensing line; the pressing force of the user is determined by measuring the amount of the change in the capacitance value so as to further determine whether the pressing force refers to "light pressing" or "heavy pressing" to invoke a corresponding instruction. In addition, according to the embodiments provided by the present application, because only four masks are required for manufacturing a related structure of touch circuit wiring, the manufacturing process is relatively simple, and the manufacturing cost can be reduced.
