Zytronic has launched a new generation of multi-touch controllers, which enable ultra-narrow inactive borders and improved compatibility with contactless systems.
In response to the growing demand for narrow screen borders, especially in interactive video walls, the new Zytronic ZXY500 touch controllers allow touch sensors to be designed with substantially reduced non-active borders. For example, a 55” diagonal touch sensor can now be designed with sub 10mm borders. A further advantage of the new ZXY500 controller is its compatibility with contactless technologies increasingly being integrated alongside displays to enable payments, customer tracking and battery charging technologies. RFID, NFC and Qi phone charging all generate wireless signals that can interfere with the operation of conventional touch screens, but the new controller has industry leading signal-to-noise ratios and sophisticated algorithms that change dynamically to reject electromagnetic interference in the operating environment.
The ZXY500 can support up to 80 simultaneous touches enabling true multi-user interactivity and the implementation of improved palm rejection functionality. It also features increased speed, updating touch co-ordinates in just 1ms at the controller output, reducing touch latency by a third compared to previous generation controllers and improving the user experience. Each channel on the device can be configured via firmware to operate in transmit or receive mode. This feature further enhances performance in applications where touchscreens of unusual aspect ratios are used.
Zytronic is releasing a family of three ZXY500 controllers optimised for different sizes of touch interface. The 64-channel ZXY500-U-OFF-64 is recommended for sensors of 5” to 20” diagonal, the 128-channel ZXY500-U-OFF-128 for sensors of 20” to 55” and the 256-channel ZXY500-U-OFF-256 for sizes above 55”.
