Abstract
A pressure-sensitive touch display panel and a driving method thereof are provided. The panel includes a substrate, an OLED structure layer and a touch electrode layer. The OLED structure layer has a cathode layer. The touch electrode layer includes driving electrodes and sensing electrodes. The pressure-sensitive touch display panel has a display stage and a pressure-sensitive touch stage within display time for one frame. In the display stage, the cathode layer loads a common voltage signal for allowing the OLED structure layer to display; in the pressure-sensitive touch stage, the touch electrode layer is configured to sense at least one touch position. When the touch electrode layer senses at least one touch position, the cathode layer loads a pressure detection signal for the touch position so as to determine level of pressure at the touch position by a change in capacitance between the cathode layer and the driving electrodes.
