Projective capacitive touch panels

Relec has teamed up with RockTouch, a projective capacitive touch-panel (PCAP) manufacturer, to bring its products to the UK.

There are 12 sizes available, ranging from 7in up to 31.5in with all having a film-film-glass (F/F/G) structure with a choice of interfaces that include USB, RS232 or I²C. Some key features of Rocktouch PCAPs are:

A bespoke controller chip provides the best possible signal-to-noise Ratio at 32 V.  This greatly helps with EMC conformance and is suitable for applications such as automotive

Up to 10-point touch

Can be operated using gloves, even thick industrial gloves

Up to 10mm-thick cover glass

Industrial COF design for added protection from electrical noise and mechanical stress

Optional firmware features including: frequency hopping; water rejection and palm rejection

RockTouch has now also released its new X-H₂0 Line that will continue to operate perfectly with running water over the cover glass. This is available in all sizes.

Relec can either supply the touch panel as a component for customer integration, or with the help of Futurelabs (RockTouch’s parent company), it can provide the touch panel as part of an assembly to include the TFT panel. In addition, it can tailor the whole assembly to your application, and modify them to include various options, for example:

Improving the brightness

Optical Bonding for high brightness applications especially outdoor. This also offers substantial mechanical improvements and is ideal for rugged applications. It also resolves the problem of condensation forming between the display and touch panel

Applying various different surface treatments

Supplying with custom-tuned Interface Cards

Making the product more rugged
