  • Publication number: 20220066585
    Abstract: The present application relates to a touch display panel and an electronic device. The touch display panel includes: a substrate; and a light-emitting unit layer locating on a side of the substrate comprising a cathode metal layer reused as a touch electrode layer and multiple light-emitting units arranged in an array; the light-emitting units each have a light-emitting cycle comprising a first time period and a second time period staggered from the first time period; the cathode metal layer accesses a touch drive signal when the light-emitting cycle is within the first time period, and the cathode metal layer accesses a display drive signal when the light-emitting cycle is within the second time period. The cathode metal layer according to the present application is reused as the touch electrode layer, and inputs different drive signals in different time periods, which can greatly reduce a thickness of the touch display panel.
