The capacitive touch screens respond to fingertip input control without requiring application of any pressure. The structures are very robust and the sensor elements will not wear out. Lifetimes are approximately 100 million touches.
Optrex’s capacitive touch switch solutions provide outstanding clarity and ease of design. Improved visibility results from less reflectivity and higher transparency of the image displayed through the touch panel and allows for a thinner touch screen in front of the LCD (up to 0.5 mm - 0.7 mm thick in the viewing area). Transparency is a minimum of 95% and reflection is less than 15%. The capacitive touch screens also have a wide operating temperature range of -20 to 70°C.
