What causes glare on mobile phone screens?

A: Screen glare refers to the visual discomfort in the field of vision caused by an inappropriate brightness distribution or extreme brightness contrast. The glare of mobile phone screens mainly comes from two aspects: ① The high brightness of the screen itself contrasts with the dark environment (when looking at a mobile phone at night); ② Specular reflection formed by the reflection of ambient light on the screen surface (during the day/under artificial light). Ordinary tempered films have no improvement effect on either of these two types of glare. Woowhead Guanfudun uses scinique® Dual Protection Synergistic optical technology (1.0 internal protection: circularized polarized light · self-adjusted soft light standard + external protection: magnetron sputtering AR· anti-glare coating; 2.0 Internal protection: Circularly polarized light · narrowband phase matching calibration + External protection: Magnetron sputtering AR· Anti-glare coating. Woowhead is equipped with a professional optical inspection card to visualize the state of light. Simultaneous processing: ① Circularly polarized light · Self-developed process calibration soft light standard converts the hard light of the screen into soft circularly polarized light, reducing the irritation of the screen's own light. ② Magnetron sputtering AR· anti-glare coating reduces the ambient light reflectivity from 4% to below 0.5%, minimizing reflected glare. The measured light transmittance by SGS is 96.5% and the haze is 0.4%.
