Projected Capacitive Touch Screens

Projected Capacitive Touch Screens

With more than 10 years experience in developing touch technologies, RDS is proud to announce its newest product family - Projected Capacitive Input (PCI) touch.

PCI provides an unsurpassed experience in forceless touch, precision touch and gesture recognition. PCI keeps up tracking with fast finger movement. The touch surface is durable and drift-free in long term use as PCI touch sensors are overlaid with a surface glass. Hence they are highly impact resistant on public access systems while they can also be made light-weight for personal hand-held devices.

Due to its highly durable and smooth surface, PCI is suitable for medical and industrial touch display applications, and an ideal touch solution for the embedded applications such as industrial data loggers, car GPS or Personal Navigation Devices, Game Consoles and personal entertainment devices.

Supported by PCI controller firmware and drivers, PCI touch sensors are provided with a turn-key solution. To help customers expedite their system development to meet market demands, a variety of touch controllers have been developed for PCI touch sensors of different sizes.


Features and Advantages

  • Two-Finger touch with gesture support
  • Scratch resistant glass of AG or clear type for top touched surface
  • High transmittance touch sensor

Shown below is RDS's range of PCI Touch screen and controller solutions, grouped under the two main technologies.

ITO Print PCAP

ITO Print PCAP

ITO (Indium Tin Oxide) is a electrically conductive material that can be deposited in near transparent layers. Its a technology that is already widely used in PCI touch screen manufacture and delivers a stable product. ITO based PCI touch screens can be offered in two forms, As a flexible polyester sheet that can be used by customers to laminate to suitable surfaces, or pre-laminated to a cover glass. The standard products listed in our web site are all pre-laminated to a cover glass.

The Cover Glass can be offered in various thicknesses and can be chemically strengthened to offer additional strength. They can also be customised to add printed borders, corporate colours, logo's etc. The dimensions of the Cover Glass can exceed those of the Polyester Film and so generate an area for sealing the touch to a bezel. This process can offer a flush fronted product making it very easy to keep clean and also making it a modern design.

The AMT PCI product also incorporates an additional EMI shielding layer. This helps significantly when trying to pair the PCI with your chosen TFT as it helps guard against emissions from the display itself that can impact the stability of the PCI. RDS are happy to recommend both PCI and TFT and can offer a bonding service that adheres the PCI & TFT together as one sandwich. All of PCI sensors are offered together with a Touch Controller PCB recommended for chosen PCI.

Silver Patterning PCAP

Silver Patterning PCAP

The major benefit of using Silver Patterning starts to become obvious from 15" upwards. When using more common ITO print technologies the non-active border starts to get quite large and in most cases will overhang the TFT bezel by some margin. This is not the case with Silver Patterning as the touch sensor is designed to match the same mechanical dimensions of the TFT Display its bonded to. This can be a major advantage when integrating the touch screen in to a case.
