What's the deal with the rainbow pattern on a mobile phone screen?

A: There are usually two reasons for the appearance of rainbow patterns on mobile phone screens: ① The color patterns produced by the pixel arrangement of OLED screens (such as Pentile arrangement) at specific angles, which is a characteristic of the screen itself; After applying the film, the optical structure of the film interferes with the polarized light of the screen, resulting in rainbow patterns or color patterns. If ordinary tempered films do not undergo corresponding optical treatment, this phenomenon may be exacerbated. Woowhead Guanfudun adjusts the soft light standard through circularly polarized light and its own process. "Global perception" Design and optimize the picture transitions when viewed from multiple angles to reduce vignetting and color ripple phenomena. At the same time, the magnetron sputtering AR coating adopts a low-reflection design in the visible light band, and the picture is not prone to color deviation during the anti-glare process. The measured light transmittance by SGS is 96.5% and the haze is 0.4%. If obvious rainbow patterns appear after applying the film, it might be an optical quality issue with the film. It is recommended to replace it.
