Abstract

The invention relates to an anti-UV protective film of an OLED screen body for a vehicle light. The anti-UV protective film comprises release paper, an adhesive layer, a resin film and a UV barrier layer which are arranged in sequence from bottom to top, and has the total thickness of 40 to 100 [mu]m; the resin film contains an ultraviolet absorbent; the visible light transmittance of a composition comprising the adhesive layer, the resin film and the UV barrier layer is 75 to 90 percent; the adhesive layer is used for connecting the OLED screen body with the resin film, and has the characteristics of low volatilization and low fogging degree; the resin film is made of PET or PEI resin, thus guaranteeing the high-temperature resistance and the tear strength of a protective film main body;the ultraviolet absorbent is UV-P or UV-531. With the barrier rate of 95 to 100 percent, the anti-UV protective film can prevent ultraviolet radiation at the wavelength of 5 to 430 nm; the anti-UV protective film is high in adhesiveness, can resist high temperature, is easy to construct, and provides a good anti-UV radiation effect for the OLED screen body for the vehicle light.

Description

technical field [0001] The invention relates to an ultraviolet protective film, in particular to an anti-UV protective film suitable for an OLED screen body used in a car lamp. Background technique [0002] Up to now, the mainstream of light sources used in the automotive lighting industry is still light bulbs and LEDs, especially in the field of automotive rear lights. Their ability to adapt to environmental changes is very limited, the efficiency of the light source is not high, and there are certain safety risks. Therefore, with the development of new technologies for intelligent rear lights, a high-efficiency and energy-saving planar distributed OLED (organic light-emitting diode) car light has emerged as the times require. [0003] OLED technology is currently widely used in mobile phones and home appliance displays, indoor stadium signs and other fields. It has many advantages such as thinness, wide viewing angle, high contrast, and self-illumination. However, polymer...
