Abstract
The present invention provides a force touch display device and a force touch control method. The force touch display device includes a substrate, an organic light emitting diode (OLED) layer disposed on the substrate, a strain layer disposed on the OLED layer, and a touch function layer disposed on the strain layer; wherein the OLED layer comprises an anode disposed on the substrate, a light emission layer disposed on the anode, and a cathode disposed on the light emission layer and comprising a pressure detecting pattern; wherein when force touch is performed, touch detection is performed by the touch function layer, and pressure detection is performed by cooperation of the cathode and the touch function layer. By multiplexing the cathode of the OLED as a pressure induction electrodes, the force touch can be achieved without increase of a thickness of a product to improve competitivity.
