Abstract
An OLED touch display substrate, an OLED touch display panel, a display device and a control method thereof are provided. The OLED touch display substrate includes an anode, a cathode and a functional layer arranged on a base substrate. The cathode includes sub-cathodes, a time period for displaying one image frame of the OLED touch display substrate includes a display time period and a touch time period, and the sub-cathodes further serve as touch electrodes. The touch display substrate further includes touch signal lines electrically connected to the touch electrodes. Within the display time period, a common voltage signal is applied to each touch electrode via the respective touch signal line. Within the touch time period, a touch scanning signal is applied to each touch electrode via the respective touch signal line, and it is detected whether or not a self-capacitance of the touch electrode changes.
