Technical Field

[0001] The utility model relates to the technical field of OLED display screen manufacturing, in particular to a pressing device. Background Art

[0002] Organic Light-Emitting Diode (OLED) is a current-type organic light-emitting device that emits light through the injection and recombination of carriers. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules and ultimately producing visible light.

[0003] In the entire OLED production process, packaging is a very critical process. The organic materials used in OLED light emission require water-free and oxygen-free conditions, so the entire packaging process needs to be carried out in a nitrogen environment. Since the gas used in the packaging chamber is nitrogen, the chamber needs to maintain a dry environment for a long time.

[0004] At present, due to frequent contact between the corresponding platforms, substrates and manipulators in a long-term dry environment, static electricity is easily generated. The frequent pressing process further accumulates static electricity, and the products are damaged by static electricity, resulting in defects or scrap. Utility Model Content
