How to test the performance of the Anti-UV touch screen panels?
May 5, 2025
Many customers ask when purchasing Anti-UV G+G touch screen panels, 'How strong is your Anti-UV performance?'? How to prove it? ”Today, we will talk about the testing methods for Anti-UV performance to help you evaluate product quality more scientifically.
1. Laboratory accelerated aging test
Before formal mass production, we will place the G+G touch screen panels samples in a UV aging test chamber to simulate prolonged exposure to ultraviolet radiation. The testing standards usually refer to ISO 4892 or ASTM G154, and the screen is observed for yellowing, fogging, touch failure, and other phenomena by continuous exposure to high-intensity UV lamps for hundreds of hours.
2. Outdoor actual environment testing
Laboratory data is certainly important, but the real environment is more complex. Therefore, we will conduct long-term outdoor tests in different climate regions (such as the hot and humid south, the strong ultraviolet Qinghai Tibet Plateau, etc.) to record the performance of the screen in different seasons. For example, after being exposed to sunlight in Hainan for 6 months, the light transmittance of a certain car G+G touch screen panels still remains above 92%, and the touch function is completely normal.
3. Key performance indicators
When evaluating Anti-UV G+G touch screen panels, you can pay attention to the following key data:
Change in transmittance (compared before and after UV irradiation, the change in high-quality products should be<3%)
Surface hardness (Anti-UV coating usually reaches 7H pencil hardness, scratch resistant and wear-resistant)
Touch stability (whether there is drift or malfunction after long-term UV irradiation)
As a G+G touch screen panels manufacturer, we not only provide test reports, but also support customer sample testing. If you have special UV resistance requirements (such as extreme environmental applications), we can also adjust the coating formula to provide a higher level of protection solution.
