Core Technical Features
| Integrated Visual & Touch Design |
| Custom patterns/logos (e.g., backlit icons, brand logos) can be directly printed on PET film,Simultaneously, the highly transparent PEDOT:PSS layer (transmittance ≥85%) enables precise capacitive touch sensing. |
| Automotive-Grade Materials & Processes |
| Substrate : High-strength, temperature-resistant PET film (standard thickness: 125μm; options: 100um/188μm). |
| Circuit Structure : Precision-printed silver conductive traces + protective carbon layer, ensuring superiorconductivity, oxidation resistance, and mechanical durability. |
| Transparent Electrode :Screen-printed PEDOT:PSS conductive ink, offering high transparency and stable conductivity. |
| Optical Lamination:High-transmittance, low-haze OCA with vacuum lamination for bubble/wrinkle-free performance. |
| Exceptional Environmental Resilience |
| Wide Operating Temperature : -40℃ to +85℃ (extendable to +105°C upon request). |
| High Humidity Resistance : Stable operation at 95%RH. |
| Weather Resistance:Passes UV aging,damp heat,thermal shock tests-no yellowing, cracking, or performance degradation. |
| Chemical Resistance: Withstands automotive cleaners, sweat, oils, etc. |
| Longevity :>10-year lifespan (per typical automotive use); validated via vibration, shock, and bend tests. |
| Environmental Compliance |
| Meets VOC emission standards (e.g., GB/T 27630, VDA 270, ISO 12219) for cabin air quality. |
| Complies with RoHS, REACH, and other international regulations. |
