In-cell touch panel, display device and driving method thereof
An in-cell touch panel, a display device and a driving method thereof. The in-cell touch panel includes: an array substrate and an opposing substrate that are arranged opposite to each other; touch detection electrodes; touch-pressure sensing electrodes disposed between a layer provided with the touch detection electrodes and a base substrate of the array substrate. A capacitor structure is formed by the touch-pressure sensing electrodes and a metal layer disposed below the array substrate; and a touch detection chip configured to simultaneously apply touch detection signals to the touch detection electrodes and the touch-pressure sensing electrodes in a touch period, determine a touch position by detecting capacitance variations of the touch detection electrodes, and determine a touch pressure value by detecting capacitance variations of the touch-pressure sensing electrodes.
