How to choose touch screen materials suitable for aviation applications

In the procurement of aviation electronic equipment, the selection of  PCAP touch screens often makes engineers particularly cautious. After all, this is related to flight safety. As a company with 15 years of experience in manufacturing aviation display equipment, Shenzhen Xinlilai Touch Technology Co., Ltd. summarizes the five key points for selecting materials for aviation PCAP touch screens, hoping to be helpful for you when choosing touch screens.
 

1. Selection of substrate materials
It is recommended to use chemically strengthened microcrystalline glass instead of ordinary soda lime glass. Our test data shows that under the same thickness, the impact resistance of microcrystalline glass is improved by 300%, making it more suitable for cockpit environments that may encounter bird strikes.
 

2. Comparison of conductive layer schemes
ITO solution: Low cost, but poor low-temperature performance
Metal mesh: excellent electromagnetic compatibility, recommended for use in avionics systems
Nano silver wire: optimal folding resistance, suitable for deformable display devices
 

3. Environmental adaptability treatment
Must consider:
Anti mold coating (compliant with MIL-STD-810 method 508.6)
Salt spray protection (meets the requirements of DO-160G Chapter 14)
Anti static treatment (surface resistance controlled at 10 ^ 6-10 ^ 9 Ω)
 

4. Balance of optical performance
Suggested parameter range:
Transmittance ≥ 90%
Foggy ≤ 1%
Color difference Δ E<2
 

5. Certification requirements
Essential certifications include:
FAA TSO certification
EASA ETSO accreditation
Declaration of Airworthiness Directive Compliance
