Abstract:
A method of manufacturing an OLED panel and an OLED panel are provided. The method includes forming an anode connected to a source of a TFT, and a strap electrode connected to an auxiliary electrode on a TFT substrate. A sharp shaped corner is formed on the strap electrode, therefore an area of the electron transport layer and the electron injection layer corresponding to the sharp shaped corner have a thinner thickness. By applying a voltage between the auxiliary electrode and the cathode, the electron transport layer and the electron injection layer corresponding to the sharp shaped corner are punctured, the cathode is directly connected to the strap electrode and further conducted to the auxiliary electrode, resulting in a signal is inputted to the cathode through the auxiliary electrode during display. The problem of uneven display of the OLED panel due to the IR drop of the cathode is improved.
