1.The cover glass is coated with high-performance AF hydrophobic coating with a water contact angle ≥ 110°. Water droplets roll off rapidly without forming continuous water films. The coating features excellent abrasion resistance and weather resistance, and will not peel off after long-term use.
2.The screen is installed with a downward tilt. The frame is designed with rounded chamfers and drainage grooves to eliminate water accumulation. A rain shield is mounted on the top to reduce direct rain exposure.
3.The dedicated condensation recognition algorithm accurately distinguishes human touch from interference from large-area water films and condensation. It automatically blocks continuous false touch points to eliminate ghost touches and screen flickering.
4.When water is detected on the screen, the system automatically raises the touch trigger threshold and extends judgment duration to filter transient interference from water droplets. It restores normal parameters once the water fades away.
5.Adopt G+G full lamination process with water-resistant OCA adhesive. The four sides of the screen are fully and continuously sealed to block interlayer gaps and prevent moisture from invading the ITO layer.

How to solve aging issues caused by long-term outdoor sun exposure?1.Replace conventional ITO with high weatherability conductive layer and low-attenuation UV-resistant ITO film. It features excellent resistance to temperature variation and ultraviolet rays, with negligible resistance change under long-term thermal cycling and sun exposure. This slows down circuit oxidation and resistance drift, and prevents local circuit breakage. The edge electrodes are thickened and the traces widened to reduce stress and concentrated aging caused by sunlight.
2.Adopt ultra-clear borosilicate tempered glass incorporated with UV absorbers to block ultraviolet penetration. It features a low coefficient of thermal expansion, so it will not deform or strain conductive circuits under temperature changes, effectively slowing down aging from the base.
3.All OCA optical adhesives, edge sealants, back adhesives and foams are UV-resistant and capable of withstanding high and low temperature aging. Formulated with antioxidants and UV stabilizers, they resist yellowing, embrittlement and delamination during long-term operation, preventing circuit damage caused by adhesive failure.
4.Equip the device with an integrated sun visor and optimize the installation angle to cut down direct sunlight exposure and UV radiation intensity. Light-shielding layers are added inside the housing and module to block ultraviolet rays from reaching internal circuits.
5.Heat insulation pads and elastic buffer pads are installed between the module and housing to reduce heat conduction in summer and cold impact in winter, narrowing temperature differences on the screen and mitigating material fatigue from thermal cycling. The floating mounting design relieves deformation stress and prevents micro-cracks on circuits.
6.The device features IP65 or higher sealing performance paired with waterproof and breathable membranes to prevent condensation caused by temperature differences. Since moisture accelerates oxidation and corrosion of conductive layers, this dual protection effectively extends the service life of internal circuits.
7.Adopt aging-resistant industrial-grade FPC with properly reserved wire length and positioning structure. All solder joints are reinforced with extra solder and fully encapsulated with glue to prevent desoldering and circuit aging caused by temperature changes and vibration.
FAQ1.Q: Will the touch module age quickly under long-term outdoor sunlight?A: No. We use UV-resistant ITO film and UV-blocking glass, plus anti-aging adhesives, to ensure stable performance under prolonged sun exposure.
2.Q: What prevents the glass and conductive circuits from deforming with temperature changes?A: Low expansion borosilicate glass, heat insulation pads and floating mounting are applied to reduce stress and avoid circuit damage.
3.Q: Do adhesives turn yellow or peel after long-term use outdoors?A: All adhesives and foams contain antioxidants and UV stabilizers, resisting yellowing, embrittlement and delamination.
4.Q: How to protect internal circuits from UV and condensation damage?A: Sun visors and light-shielding layers block UV rays. IP65 sealing and breathable membranes effectively avoid condensation.
5.Q: Are wiring and solder joints reliable in harsh outdoor conditions?A: Industrial-grade FPC and fully encapsulated solder joints withstand temperature swings and vibration to prevent desoldering.
