Problems solved by technology

The touch electrodes and sensing electrodes of the display panel are arranged on the light-emitting surface side of the OLED substrate. Usually, the sensing electrodes are formed by a patterning process with the cathode of the OLED device on the OLED substrate (both are arranged on the same layer and made of the same material. ), so the electric field formed between the touch electrode and the sensing electrode can easily affect the cathode, resulting in abnormal light emission of the OLED, which in turn makes the OLED display panel unable to display normally.
