Projective capacitive touchscreen controllers

Our PCAP touchscreen controllers are designed to deliver a smooth user experience and meet the criteria for rugged applications, capable of working in the most extreme of environments.

This technology is available in PCBA (Printed Circuit Board Assembly) or COF (chip-on-flex) format. The touch input force is feather-light, and multi-touch technology offers a level of diversity for suitable applications.

The EXC84 family supports small to mid-size PCAP touchscreens with the most desired industrial features; as for ultra-large, the EXC86 family is capable of supporting most of the ultra-large sized PCAP touchscreens.

Resistive touchscreen controller boards

Resistive touchscreen technology is a cost effective solution and easy to assemble, but above all, it is an ideal solution for applications that need to operate in wet screen conditions and/or high-power noise environments.

At GSR Technology our range of 4, 5 and 8 wire resistive touch controllers offer excellent compatibility with the wide range of resistive touch sensors already in the market. Our controllers are available with USB, RS232, and I2C and PS2 are also available as special designs.
