Display and Touchscreen

Display and Touchscreen
The VX4 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:
An extra or replacement stylus may be ordered from LXE. See the "Accessories" section for the
stylus part number.
Although the touch screen is installed and calibrated at the factory, users may make adjustments to
it by using the Hampshire TSHARC Control Panel on the Microsoft Windows Programs menu.
Please refer to your System Administrator or the VX4 Reference Guide for information on touch
screen calibration.

Cleaning the Display

Keep fingers and rough or sharp objects away from the scan aperture and 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.

Adjust Screen Display

The color TFT display is an active source of light. There are no provisions for adjusting the
brightness or 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 time.
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.
The <F4>, <F5>, <F6>, and <F7> keys on the VMT keyboard have no function as the
VX4 has a TFT screen.
