  • Publication number: 20160098953
    Abstract: A display panel with an electrostatic discharge (ESD) protection function, includes a organic light emitting diode (OLED) light area, a scan driving circuit, and a data driving circuit. Therein, the OLED light area includes a number of pixel regions which are arranged in array mode. The scan driving circuit and the OLED light area are connected to each other via a number of scan lines which are fanned out. The data driving circuit and the OLED light area are connected to each other via a number of data lines which are fanned out. Therein, each data line is connected to one voltage point via a first OLED, each scan line is connected to one voltage point via a second OLED.

  • Patent number: 9076992
    Abstract: Disclosed is a method for preventing a short circuit between metal wires in an organic light emitting diode display device. The method includes: forming an inorganic layer on a substrate; forming a metal layer including two metal wires on the inorganic layer; forming an organic layer on the two metal wires; forming an indium tin oxide layer on the organic layer; coating a photoresist layer; performing an exposure step by utilizing a photo mask having a transparent area, an opaque material disposed in the transparent area, wherein a width of the opaque material is less than a width of the transparent area; performing a development step to the photoresist layer; and performing an etching step to remove a part of the indium tin oxide layer and a part of the organic layer. The present invention can prevent the short circuit between the metal wires.
