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.

Abstract: A coating apparatus (2) includes a work table (20) having a plurality of blowing holes (201) for suspending a substrate (200) thereabove, a coating unit (22) having a photoresist coating nozzle (222) and a supplying device (224) for photoresist material. The photoresist coating nozzle is disposed above the work table, and the supplying device connects to the coating nozzle for supplying photoresist thereto. In operation, the substrate to be coated is continuously suspended in the gas just above but not in contact with the work table. Therefore, accumulation of static electricity and/or foreign particles on the substrate can be avoided. Gas emitting from the blowing holes can remove foreign particles from the surface of the work table and the backside of the work table.
