In-Cell Touch Panel, Driving Method Thereof and Display Device

An in-cell touch panel, comprising:

• a base substrate;
• an opposing substrate arranged opposite to the base substrate;
• a plurality of organic light-emitting diode (OLED) pixel units disposed on a side of the base substrate facing the opposing substrate and arranged in a matrix, wherein each of the OLED pixel units include an anode layer, an emission layer (EML) and a cathode layer disposed on the base substrate in sequence;
• a pressure-sensitive detection chip;
• and
• a plurality of mutually independent pressure-sensitive detection electrodes disposed between the cathode layer and the opposing substrate, wherein a capacitor structure is formed by the pressure-sensitive detection electrodes and the cathode layer,
• wherein the pressure-sensitive detection chip is configured to apply pressure-sensitive detection signals to the pressure-sensitive detection electrodes in a pressure-sensitive touch period, and determine a pressure value at a touch position by detecting a capacitance variation between the pressure-sensitive detection electrodes and the cathode layer.
