Analysis of vacuum vapor deposition process of the metal electrode TFT Display Module

Metal electrodes still evaporation in a vacuum chamber. A low work function metal electrode is typically used active metal, and therefore after the completion of the thin film deposition of the organic material deposition. Top metal electrode Mg / Ag, Mg: Ag / Ag, Li / Al, LiF / Al, etc.. The boat is usually used for the metal electrode deposition of materials such as molybdenum, tantalum and tungsten production (mainly to prevent the boat Metals and metal deposition from a chemical reaction), for the type of metal electrode deposition.128x32 oled
The metal electrode material evaporated ships with a heating current which means that, in the vacuum deposition equipment for deposition experiment, the experimental results show that the evaporation of the metal electrode material and the heating current ships between 70A ~ 100A (individual metal exceeds 100A) , ITO sample substrate temperature around 80 ° C, the evaporation rate of 5 crystal point to 50 points by crystal / sec (i.e., approximately 0.5 nm to 5 nm / S), the degree of vacuum vaporization chamber 7 × 10-4Pa ~ 5 × 10-4Pa when evaporation better.lcm module

OLED device of an organic thin film and the metal thin film with water and air Claim oxidation, so that the device performance is decreased rapidly, and therefore must not be in contact with air and water before packaging. Therefore, the OLED packaging process must be carried out in anhydrous and oxygen through a glove box with an inert gas (such as argon). The packaging material comprises a binder and a covering material. UV curing adhesive epoxy curing agent, covering material made of glass cover, installation of desiccant to absorb the residual moisture in the cover.lcd module
