Abstract
An OLED touch display panel and a driving method are provided. The OLED touch display panel includes a cathode layer. The cathode layer is divided into the two sub-cathodes separated from each other and also serving as touch electrodes. In a pixel circuit of the OLED touch display panel, under common operations of a first input terminal and a second input terminal fed with different voltages, the OLED touch display panel normally emits light or does not emit light.
