Plymouth, MI – Optrex America Inc. has developed an advanced capacitive touch switch technology that detects variations in position and command, eliminates air gaps and reduces the number of layers required. This technology offers the highest standards of optical performance with exceptional ease of design for human machine interfaces, handheld terminals, gaming, medical equipment, and point-of-sale and mobile applications.

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 new 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, -20°C to +70°C.

Touch screens utilizing Optrex’s technology are more compact, lighter in weight, more durable (including better resistance to liquids) and easier to clean.

Display solutions incorporating Optrex’s capacitive touch technology are currently available for demonstration and new product designs in 3.0-inch (T-55149), 3.5-inch transmissive (T-55343) and 3.5-inch transflective (T-51963). Additional sizes in 5.7-inch (T- 55265) and 6.5-inch (T-51750) diagonal will soon be available. Optrex can provide the touch switch solution alone or in combination with a TFT LCD.
