Analysis of the oled module electrode production process

Production process of the metal electrode and the organic material film to the vapor deposition chamber is isolated from the vacuum chamber for. Since the metal electrode is more active with a low work function metal, the organic material film after evaporation deposition process, do not allow the organic material film with the substrate is exposed to the air,mini lcd module to move the metal electrode deposition chamber.

Metal electrodes are used Mg / Ag, Mg: Ag / Ag, Li / Al, LiF / Al, etc., Mg / Ag to form a film by co-evaporation method, an evaporation method other layered, general metal vaporization temperature of the material 450 ℃ -1200 ℃ high temperature, so to prevent the metal evaporation source heat radiation of the organic material film on the substrate the adverse effects of the substrate temperature controlled at 80 ℃. For the alloy to be deposited metal electrode, after treatment, the alloy metal electrode film above and then coated with a noble metal film, such as Mg: Ag (10:1) alloy coated with a protective layer of silver, making Mg: Ag / Ag, the Li / Al became Li: Al / Al. In the vapor deposition of organic material film and the metal thin film 10 ⁻ ⁵ Pa to maintain the vacuum above, otherwise it will affect the organic material film and the metal thin film quality and lifetime of the device.
OLED device anti-aging treatment

OLED devices and metal organic thin film and the oxidation of water and air will immediately deteriorate,Coding System lcd module we must take measures to avoid this problem. Protection Act can be inorganic membranes and inorganic membrane protective materials are silicon nitride, magnesium fluoride, indium oxide, etc., using resistive heating method or magnetron sputtering inorganic protective film material. After the formation of the protective film, to produce a device to be packaged, the packaging process must be in anhydrous oxygen-free inert gas, packaging materials including adhesives and the cover material. Using an ultraviolet curing adhesive or heat-curable epoxy curing agent, covering materials and glass cover, the cover installed inside the desiccant to absorb residual moisture.
