Abstract
An organic light emitting diode touch display panel and a method for driving time division multiplexing are disclosed. The OLED touch display panel with a patterned cathode uses a pixel definition layer of a LTPS array substrate to form sensor pads. By adding a time division multiplexing circuit unit to each voltage signal traces outside the display area of the touch display panel, the power signal traces of the source and drain layer of the LTPS array substrate are multiplexed, and peeling during the flexible screen bending process can be prevented.
