Title:

TOUCH PANEL, TERMINAL DEVICE, AND METHOD FOR USE IN DETECTING TOUCHED POINT

Document Type and Number:

WIPO Patent Application WO/2018/102958

Kind Code:

A1

Abstract:

A touch panel (200) capable of solving the problem of reduced touch sensitivity brought forth by a suspended state. The touch panel (200) comprises: a driver module (210), a touch controller chip (220), multiple drive channels (230), and multiple sensing channels (240). The driver module (210) is connected to the touch controller chip (220). The multiple drive channels (230) and the multiple sensing channels (240) respectively are connected to the touch controller chip (220). The touch controller chip (220) is used for receiving a first drive signal and a second drive signal transmitted by the driver module so as to drive the multiple drive channels (230) to work via the voltage difference between the first drive signal and the second drive signal. The multiple sensing channels (240) are used for capturing a sensing signal. The sensing signal is a coupling signal between the multiple sensing channels (240) and the multiple drive channels (230) being driven by the voltage difference between the first drive signal and the second drive signal. The touch controller chip (220) is used for determining coordinate information of a touched point on the touch panel on the basis of the sensing signal.
