Abstract
An OLED touch display panel, a method for manufacturing an OLED touch display panel and a touch display device are disclosed. The method comprises: forming a plurality of baffles by a patterning process on a TFT back plate, wherein each of the baffles defines a touch region; and forming a cathode layer on the TFT back plate on which the baffles have been formed. The cathode layer is partitioned by the baffles into a plurality of self-capacitance electrodes insulated from each other. Each of the self-capacitance electrodes is located within one of the touch regions and matches the touch region in shape.
