Abstract

The invention discloses a technical process film for laminating a UV-irradiation viscosity reduction type OLED module and a preparation method of the technical process film. The technical process filmcomprises an anti-adsorption conductive layer A, a base material, a pressure-sensitive glue layer, a release film and an anti-adsorption conductive layer B, wherein one surface of the base material is coated with the anti-adsorption conductive layer, a corona surface and the release film on the other surface are laminated through the pressure-sensitive glue layer, the pressure-sensitive glue layer is a UV light-reducing viscose layer and has anti-static performance, and the back surface of the release film is coated with the anti-adsorption conductive layer. According to the technical processfilm disclosed by the invention, the anti-static requirement on the film surface and the back surface of the release film is increased based on an anti-static glue surface, the situation of electrostatic adsorption is avoided in the pick-up and use processes of a film piece, and the stability of the technical process is improved; and the technical process film is mainly applied to the laminationof OLED screen modules.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a process film for bonding OLED modules and a preparation method thereof. Background technique [0002] 0LED, Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminescence Display (Organic Electroluminescence Display), refers to organic semiconductor materials and light-emitting materials that are driven by an electric field to cause light emission through carrier injection and recombination. The phenomenon. Panels using OLED are inherently superior to thin-film transistor liquid crystal displays (TFT-1XD) in terms of image quality, performance, and cost. However, the life cycle of general OLED is easily affected by the surrounding water vapor and oxygen, so the AM-OLED panel needs good packaging to isolate the surrounding water vapor and oxygen. [0003] Process film is required in the packaging and bonding process of OLED modules. General...
