Overview
In conjunction with Industry 4.0 revolution, people are looking for more advance technology to be integrated into their living live. Touch control, is 1 of the most prominent topic being discussed most of the time now. Generally, there is 2 types of touch solutions we provide, Projected Capacitive (PCAP) and Infrared (IR) touch technology.
Projected Capacitive (PCAP) Touch Technology
Projected capacitive touch technology works by accurately detecting and locating touch, sensing peak change in frequency.
When a user touches the screen, capacitance occurs between the finger and the sensor grid, whereupon the sensor’s electromagnetic field is disrupted. The peak change in frequency is measured, and by determining which row and column is closest to this peak change in frequency, the position of the user’s touch can be very accurately determined.
This product is available as either a flexible foil or rigid glass panel and is ideally suited to through glass touch applications which includes outdoor kiosks, touch tables and advertising / information displays in store windows. We offer both single/dual touch and multi-touch solutions (up to 32 touch points). Smart Tech Engineering brings you the future of multi-touch today, with a range of solutions designed for new installations and retrofit applications.
Infrared (IR) Touch Technology
Infrared touch overlays are embedded in a frame around the display and emit vertical and horizontal rows of infrared LEDs and sensors.
The infrared light in the overlay creates an invisible grid of infrared beams and sensors detect touch when the plane of the grid is broken by a finger touch or other solid object such as a pen/stylus.
Infrared touch technology is more economical and scalable than projected capacitance, allowing us to create large format touch screen solutions. Another major feature is that it works with any type of display technology and does not compromise the image quality of the screen.
This multi-touch technology is available as 3, 6, 12 and 32 point touch and offers excellent touch accuracy and fast response times making it ideal for high resolution displays. Designed for internal applications on kiosks, monitors, video walls, projection screens & whiteboards.
Products include – Retrofit interactive frames, multi-touch projection screens, large format rear projection screens, touch screen monitors, interactive whiteboards, transparent LCD/OLED touch screens, mirrored interactive displays, interactive glass overlays and interactive kiosks.
