The present invention discloses a touch display panel having a pressure sensor including a first substrate, a second substrate, a display medium layer, a transparent electrode layer, a first conductive layer, a control unit and a ground electrode layer. The display medium layer is provided between the first substrate and the second substrate. The transparent electrode layer is provided on the inner surface of the first substrate, and includes a touch electrode provided in the display area. The first conductive layer is on one side of the transparent electrode layer and includes a touch wire and a pressure sensing line. The touch wires are electrically connected to one of the touch electrodes, respectively, and the pressure sensing line is electrically isolated from the touch conductor and a portion of the pressure sensing line is connected to the control unit. The ground electrode layer is provided on the surface of the second substrate, and the ground electrode layer, the pressure sensing line and the control unit constitute a pressure sensor.
Description
technical field [0001] The present invention relates to a touch display panel with a pressure sensor, in particular to a touch display panel in which the pressure sensor is integrated into the touch display panel. Background technique [0002] Nowadays, the development of touch panel technology is very diverse. Among them, capacitive touch panel has become the most widely used in mid-to-high-end consumer electronics products due to its high accuracy, multi-touch, high durability and high touch resolution. mainstream touch technology. However, today's touch panels can only execute a corresponding single command by detecting the position of the touch, but cannot further execute other commands through the touch action. For this reason, an additional pressure sensor has been developed to simultaneously detect the pressure exerted during touch, and execute corresponding commands according to the pressure. However, the existing pressure sensor is arranged outside the touch displ...
