Display and Touchscreen
The VX3X Display is a transmissive LCD display capable of supporting Half VGA graphics
modes. Display size is half screen, 640 x 240 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.
