Solutions to Shortened Service Life Caused by Long-Term Outdoor Sun Exposure
1.Multiple layers of UV-resistant anti-reflection (AR) coating are applied on the cover glass surface, blocking over 95% of UVA and UVB ultraviolet rays to fundamentally prevent UV penetration and erosion of inner layers.
2.Low-iron ultra-clear glass substrate is adopted to eliminate inherent yellowing of ordinary float glass under long-term sunlight exposure.
3.Coating process requirements: UV aging resistance, acid, alkali and oil resistance; no obvious yellowing and no coating peeling after 3 years of outdoor sun exposure.
4.The polarizer substrate is embedded with UV absorbers to prevent strong ultraviolet rays from decomposing the dye layer.
5.Adopt high-durability color filters to avoid fading and local color difference after long-term sun exposure.
6.Improve the retention rate of contrast ratio under strong sunlight, with contrast attenuation controlled within 10% after two years of sun exposure.
7.Compound a high-durability anti-fingerprint (AF) coating on the outer layer of the cover glass. The coating delivers integrated performance of UV resistance, resistance to acid and alkaline rainwater, and dust corrosion. It prevents rainwater and stains from adhering to the surface, which would otherwise intensify localized UV absorption and further cause partial yellowing and color deviation.
FAQ
1.Q: How to stop the screen from turning yellow after long-term outdoor sunlight exposure?
A: We use low-iron ultra-clear glass substrate and multi-layer UV-blocking AR coating that blocks over 95% UVA/UVB. UV absorbers are built into polarizer substrates to avoid UV-induced yellowing of inner optical layers.
2.Q: Will the surface coating peel or discolor under outdoor harsh conditions?
A: The coating meets strict process standards: it resists UV aging, acid, alkali and oil stains. No obvious yellowing or coating delamination occurs after 3 years of outdoor exposure.
3.Q: Why does surface contamination worsen screen yellowing under strong sun?
A: Stains and rain residues will absorb UV rays locally and trigger uneven yellowing. Our outer high-durability AF anti-fouling coating repels water, dust and corrosive substances to eliminate this issue.
4.Q: Does long-term sunlight cause screen fading and uneven color?
A: High-durability color filters are equipped to prevent fading and local color difference under prolonged UV irradiation.
5.Q: How much will the display contrast degrade after years of outdoor use?
A: The design optimizes strong-light contrast retention, limiting contrast attenuation to less than 10% after two years of continuous sun exposure.
