    摘要: A display panel and a method for manufacturing the display panel are provided. The method comprises forming an array driving layer, a binding terminal, a passivation layer, a covering layer and an electrode layer on a substrate, and applying a half-tone mask to perform a patterning process on the covering layer and the electrode layer, so that the covering layer forms a first covering portion connected to the binding terminal through a first through hole and a second covering portion corresponding to the array driving layer formed on the display area. The electrode layer forms a second electrode portion on the second covering portion.

    摘要: 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.
