Title:
IN-CELL TOUCH PANEL, DISPLAY DEVICE, AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/063423
Kind Code:
A1
Abstract:
An in-cell touch panel, a display device, and a driving method therefor. The in-cell touch panel comprises: an array substrate (100) and an opposite substrate (200) that are disposed opposite; touch detection electrodes (300); touch pressure sensing electrodes (400), disposed between a film layer where the touch detection electrodes (300) are located and a base substrate of the array substrate (100), a capacitance structure being formed by the touch pressure sensing electrodes (400) and a metal layer (500) located below the array substrate (100); and a touch detection chip (600), configured to simultaneously load touch detection signals to the touch detection electrodes (300) and the touch pressure sensing electrodes (400) in a touch time segment, determine a touch position by detecting capacitance values of the touch detection electrodes (300), and determine a value of a touch pressure by detecting changes of the capacitance values of the touch pressure sensing electrodes (400).
