What is this technology?
CarrollTouch infrared
technology is the survivor of harsh
applications. It's the only technology that does
not rely on an overlay or substrate to register
a touch, so it's impossible to physically "wear
out" the touchscreen. CarrollTouch technology
combines superior optical performance with
excellent gasket-sealing capabilities, so it's
an excellent choice for harsh industrial and
outdoor kiosk applications. Touched with a
finger, gloved hand, fingernail, or stylus, it
delivers a fast, accurate response every time.
CarrollTouch infrared technology is available
for flat panel solutions.
How does this technology
work? The CarrollTouch
infrared(IR) technology uses a small frame
around the display with LEDs and photoreceptors
on opposite sides, hidden behind an
IR-transparent bezel.
The Controller
sequentially pulses the LEDs to create a grid of
IR beams. A touch obstructs one or more the
beams which identifies the X and Y
coordinates.
