Touchscreen Display

The Touchscreen Display is an LCD unit capable of supporting VGA graphics modes. Display
size is 640 x 240 pixels. The touchscreen allows signature capture and touch input. A pen stylus is
included. The touchscreen responds to an actuation force (touch) of 4 oz. of pressure (or greater).
There are two types of displays available: transflective greyscale monochrome and transmissive
color. The transmissive color display is optimized for indoor lighting. It cannot be used without
the backlight. The transflective monochrome display is optimized for outdoor use but may also be
used indoors. The monochrome display has an electroluminescent backlight. The color display has
a CCFL (Cold-Cathode Fluorescent Lighting) backlight.
The transflective display appears to have a greenish hue when the display is off. The transmissive
display appears black when the display is off.

Applying the Protective Film to the Display

First, clean the display of fingerprints, lint particles, dust and smudges (see Cleaning the Glass
Display/Scanner Aperture).
Remove the protective film from it's container. Remove any protective backing from the film
sheet by lifting the backing from a corner of the film. Discard the backing.
Apply the film to the screen starting at one side and smoothing it across the display. If air bubbles
appear, raise the film slightly and continue smoothing the film across the display until it covers the
glass surface of the display.
If dust, lint or smudges are trapped between the protective film and the glass display, remove the
protective film, clean the display and apply the protective film again.

Display Backlight

The Display backlight is turned on when the unit returns from Suspend Mode. The display
backlighting feature is programmable and activates based on power source and amount of idle
time before entering the Suspend state.
See the section titled Set the Display Backlight Timer in the previous section Quick Start.
