Abstract
The present disclosure provides an OLED structure. The OLED structure includes a cathode layer, an organic light emitting layer, and an anode layer. The organic light emitting layer is located between the cathode layer and the anode layer. A reflective layer is formed under the cathode layer and the anode layer, an insulation isolation layer is formed on the reflective layer. In the present disclosure, structural modification is performed on the anode of the OLED structure to directly avoid possibility of hill lock in the anode. Thus, improvement in the reliability, productivity and yield of the OLED is ensured.
