OLED vacuum coating drying system

Abstract

The invention discloses an OLED vacuum coating drying system. The OLED vacuum coating drying system involves a square box body, wherein a manual rotating head is arranged at the position, close to theupper side, of the middle position of the front end surface of the square box body, a current evaporator is arranged at the position, close to the left side, of the outer surface of the square box body, and a front body shell is fixedly arranged at the position, close to the lower side, of the middle position of the right end surface of the square box body; and a butt joint through pipe is arranged in the middle position of the upper end surface of the current evaporator, and a vacuum oval box body is arranged at the position, located on the upper end surface of the butt joint through pipe, of the upper portion of the current evaporator. According to the OLED vacuum coating drying system, substrate main bodies can be simultaneously and uniformly coated, and charged particles in external air and other factors are prevented from influencing the coating process of the substrate main bodies, so that the surfaces of the substrate main bodies are prevented from being contaminated by organicimpurities and dust particles, the OLED coating success rate is ensured not to be influenced by external factors, and the loss of a coating material is reduced; and selective regulation and control of coating can be carried out according to different distribution of substrate ITO so that the system can selectively regulate the coating function for different OLEDs.

Description

technical field [0001] The invention belongs to the technical field of vacuum coating, in particular to an OLED vacuum coating drying system. Background technique [0002] OLED is called organic electric laser display and organic light-emitting semiconductor; OLED is a current-type organic light-emitting device, which is a phenomenon of luminescence caused by carrier injection and recombination, and the luminous intensity is proportional to the injected current; OLED in the electric field Under the action of the anode, the holes generated by the anode and the electrons generated by the cathode will move, inject and migrate to the hole transport layer and the electron transport layer respectively to the light-emitting layer; when the two meet in the light-emitting layer, energy excitons are generated, thereby The luminescent molecules are excited to finally produce visible light, and in the vacuum coating of OLED, the electron beam is heated by current, bombardment heating an...
