Display and Touchscreen
The VX5 Display is a thin-film transistor display capable of supporting SVGA graphics modes.
Display size is 800 x 600 pixels. The display covering is designed to resist stains. The touch
screen allows signature capture and touch input.
The touch screen is a Resistive Panel with a scratch resistant finish that can detect touches by a
stylus, and translate them into computer commands. In effect, it simulates a computer mouse.
Only Delrin or plastic styluses should be used.
Note: Always use the point of the stylus for tapping or making strokes on the display. Never use
an actual pen, pencil or sharp object to write on the touch screen.
An extra or replacement stylus may be ordered from LXE. See the “Accessories” section for the
stylus part number.
Adjusting Screen Display
The color TFT display is an active source of light. The VX5 display brightness can be adjusted
via the brightness control buttons located on the VX5 control panel. Pressing the brightness up
button increases the display brightness incrementally until maximum brightness is achieved.
Likewise, pressing the brightness down button decreases the display brightness until minimum
brightness is achieved. Because there are 64 incremental levels of brightness intensity, a single
press of either brightness adjustment button may not be noticeable. The up or down button can be
pressed and held to accelerate brightness adjustment.
Note: The 2
nd
functions <F4>, <F5>, <F6>, and <F7> keys on the 60-key VMT keyboard
have no function on the VX5.
There are no provisions for adjusting the contrast of the display. The display remains on unless
Microsoft Windows power management is configured to turn the display off after a certain period
of inactivity.
Cleaning the Display
Keep fingers and rough or sharp objects away from the display. If the glass becomes soiled or
smudged, clean only with a standard household cleaner such as Windex® without vinegar or use
Isopropyl Alcohol. Do not use paper towels or harsh-chemical-based cleaning fluids since they
may result in damage to the glass surface. Use a clean, damp, lint-free cloth. Do not scrub optical
surfaces. If possible, clean only those areas which are soiled. Lint/particulates can be removed
with clean, filtered canned air.
Disabling the Touchscreen
The touchscreen can be disabled, if desired. For more information, please refer to “Disabling the
Touchscreen” in the “VX5 Reference Guide”.
Touchscreen Protective Film
LXE offers a replaceable touchscreen protective film to protect the touchscreen when the VX5 is
used in an abrasive environment. Installation and removal instructions can be found earlier in this
guide.
