What are touch screen panels made of for aircraft applications?

In the aviation industry, the application environment and material standards of touch screens are much stricter than those of ordinary consumer electronics products. From extreme temperature changes at altitudes of tens of thousands of meters to strong electromagnetic interference, aviation touch screens must have extraordinary stability. As professionals of Shenzhen Xinlilai Touch Technology Co., Ltd., today we will unveil the special material composition of aviation grade touch screens.
 

The core of aviation touch screens lies in the three words "reliability". Compared with ordinary touch screens, there are significant differences in material selection:
 

1. Reinforced glass substrate: Aviation touch screens use aluminum silicate glass with a higher degree of chemical tempering, usually with a thickness of 3mm or more, which can withstand stress changes in high-altitude and low-pressure environments. We also use anti glare treatment to ensure clarity and readability under various lighting conditions.
 

2. Military grade conductive layer: Ordinary ITO is prone to microcracks in extreme environments. We use metal grids or nano silver wires as alternatives, which provide more stable conductivity and temperature adaptability up to -55 ℃ to 125 ℃.
 

3. Special bonding material: aviation grade optical adhesive (OCA) is used, which has excellent anti-aging performance and will not yellowing or degumming under long-term ultraviolet radiation. The thickness of the adhesive layer is precisely controlled within 0.1mm to avoid the problem of high-altitude expansion.
 

4. EMI shielding design: Integrating a copper mesh shielding layer into the touch screen structure effectively resists complex electromagnetic interference on aircraft. Our test data shows that the shielding effectiveness can reach over 60dB.
