TFT Touch Panels @ Relec Electronics Ltd

RELEC is proud to offer a comprehensive range of PCAP and resistive touch panels with a variety of options. These include custom cover glass graphics as well as apertures for LEDs or USB ports. We can also incorporate capacitive switches behind the cover glass for more bespoke solutions.

RELEC’s range of touch panels is suitable for applications from commercial grade to high end automotive and military. We have solutions with noise immunity up to 32V/m which suit medical, automotive and avionic applications. In fact anywhere where operation and reliability are mission-critical. Projective capacitive touch panels (PCAP) offer the most responsive, sensitive and durable type of touch screen technology.

The PCAP sensor is constructed from a grid of conductive material which is layered on sheets of glass. An electrostatic field is then created once a
voltage is applied. When a conductive object (e.g. finger) comes into contact with the sensor, the PCAP controller measures the change in capacitance at that point which is then accurately converted to the X and Y coordinates.

Because a PCAP panel senses a touch by projection through an outer layer, this means that the top cover lens can be constructed from strengthened glass. This makes it the perfect solution for outdoor or harsh applications.
