Benefits of technology

This patented technology uses an optical component called a covering sheet that blocks certain colors outside its viewing area while still allowing visible lights like red or green rays pass through it for better image clarity. It also protects these colored materials during use without being damaged due to their exposure to sunlight over time. Overall, this technical effect improves the performance and lifespan of organic electroluminescence (OEL) displays

Problems solved by technology

The technical problem addressed by this patented technology relates to exposure to UV lights that can damage certain parts inside an electronic device's screen due to their ability to absorb these wavelength ranges from 280 nm upwards. This affects how well it works overtime without losing any functionality.

Abstract

An embodiment of the invention discloses a cover plate, a preparation method thereof and a display device. The cover plate comprises a glass substrate and a filter film, wherein the filter film is arranged on the glass substrate and used for preventing blue-violet light on the side of the glass substrate from penetrating through the cover plate. According to the cover plate, the filtering function of the filter film is utilized, blue-violet light in external light is prevented from penetrating through the cover plate and entering an OLED display panel, the risk that the blue-violet light in the external light irradiates a blue light-emitting material of the OLED display panel, and consequently the blue light-emitting material is damaged is avoided, the blue light-emitting material is protected, the light emitting quality of the OLED display panel is protected, and the service life of the OLED display panel is prolonged.
