Medical Touch Screen Capacitive Touch | Ever Glory

Specifications:

Solutions to Surface Chemical Corrosion
1.Adopt long-lasting perfluorinated AF coating. It withstands repeated wiping with 75% medical alcohol and sodium hypochlorite disinfectant, resists chemical corrosion and coating whitening. Featuring high hardness, it resists peeling and flaking even after frequent wiping, while maintaining smooth touch and high sensitivity.

2.A chemical-resistant primer based on chlorine and alcohol resistant resin is applied as the base layer to prevent disinfectants from penetrating into the substrate and conductive layer. The top layer is coated with high weatherability AF coating. This dual-layer protection effectively blocks chemical corrosion pathways.

3.Adopt full lamination plus edge sealing process to seal gaps. It prevents alcohol and disinfectants from seeping in and corroding the ITO conductive layer and circuits, thus avoiding resistance drift, touch failure and reduced sensitivity.

4.The glass surface is treated with plasma activation before coating application, which greatly enhances coating adhesion and prevents delamination after repeated wiping.

5.The coating adopts high-temperature curing process. Unlike air-dry coatings at room temperature, it delivers doubled chemical stability and scrub resistance after curing.

Solutions to Unresponsive Touch with Wet Hands
1.Increase the signal sampling frequency and enhance the recognition of weak capacitive signals. It works well with low-sensitivity signals from both thin and thick nitrile & latex sterile gloves.

2.Enable glove touch mode and wet-state anti-interference algorithm. It filters noise caused by moisture and residual disinfectant to eliminate touch drift and lag. Optimized touch thresholds lower activation requirements for normal operation without bare hands.

3.Different from traditional passive capacitive screens, active capacitive screens actively emit sensing signals. They support stable activation even with thick insulating gloves and wet hands, completely eliminating reliance on human body conductivity. This has become the mainstream choice for medical applications.

FAQ
1.Q: Can the touch screen work normally with wet hands and disinfectant residue?
A: Yes. Equipped with wet-state anti-interference algorithm and high-performance AF coating, it filters signal noise and resists liquid interference to ensure stable operation.

2.Q: Is the coating resistant to repeated wiping with medical disinfectants?
A: Absolutely. The dual-layer coating structure and high-temperature curing process deliver excellent resistance to 75% alcohol and sodium hypochlorite, with no whitening or peeling.

3.Q: Does it support operation with medical sterile gloves?
A: Yes. With upgraded signal sampling and optimized touch threshold, it adapts to both thin and thick nitrile & latex gloves. The active capacitive design ensures steady response.

4.Q: Will disinfectants seep into the screen and damage internl circuits?
A: No. Full lamination and edge sealing process, together with chemical-resistant primer, effectively block liquid penetration and protect ITO layers and circuits.

5.Q: How long can the surface coating last under frequent cleaning?
A: The plasma activation treatment and high-hardness AF coating greatly improve adhesion and scrub resistance. It maintains stable performance after long-term repeated wiping.
