Abstract
The present invention provides an OLED backplate structure. Multiple auxiliary conducting layers contacting the cathode are provided under the cathode of the OLED, which can diminish the electrical resistance of the cathode to enhance the conductivity of the cathode and to even the in plane voltages. The uniformity of the OLED display can be improved to prevent the uneven brightness issue and to decrease the thickness of the cathode for saving the production cost.
