A custom designed and printed ZYBRID touch sensor was developed for the ILS 22G – delivering the touch interaction needed with both a high degree of accuracy and rapid responsiveness. The patented projected capacitive touch sensing mechanism, at the heart of each Zytronic touch sensor, consists of a matrix of micro-fine capacitor elements embedded into a highly durable laminated glass substrate. This substrate can be positioned behind a protective overlay (>10mm thick), so that the touch sensor’s active area is not left vulnerable to sources of potential damage. Front-facing touch sensors like resistive or surface capacitive are conversely prone to various forms of harm. This gives PCT much greater resilience to shock, vibrations, scratches, harmful chemicals and exposure to extreme weather conditions – thereby maximising the touchscreen’s operational lifespan. Furthermore, unlike surface acoustic wave (SAW) or infrared (IR) touch sensing solutions, PCT supports drift-free operation, avoiding the need for costly maintenance or recalibration to be undertaken. It also dispenses with the necessity of a bezel in which to house sensor devices.
