Chapter 2 – Infrared Touch Screen Option
Description
The IRTouch Systems Infrared Touch Screen is a thin bezel mounted between the rear of the front panel and
the LCD display. It is mechanically mounted and sealed to maintain the IP65 rating of the front of the display.
The touch screen provides 4096 x 4096 touch point resolution and any object greater than 8mm diameter
including gloves can be used for touch activation. Touch activation occurs by breaking the beams of infrared
light crossing the display.
Figure 7 – Infrared Touch Screen Example
The touch screen supports multi touch gesturing allowing dynamic zooming, rotating and dragging when used
with a compatible operating system such as Windows 7. Drivers are available for other operating systems
supporting traditional single touch.
Figure 8 – Examples of Dual Touch Gesturing
There are several advantages to IR Touch versus other touch technologies including the ability to use a gloved
finger or other pointing device in conjunction with an Anti-Reflective filter for superior image clarity and
brightness. IR Touch also generates no inherent EMI as compared to resistive or capacitive touch.
