Display

The display is a thin-film transistor display capable of supporting WVGA graphics modes. Display size is 800 x 480 pixels. The
display covering is designed to resist stains. The touch screen allows signature capture and touch input. The display supports
screen blanking to eliminate driver distraction when the vehicle is in motion.

Touch Screen

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. A right
mouse click is simulated by touching and holding the screen for the appropriate time interval.
When a dialog box is too large for the display, tap and drag the dialog box up or down or from side to side to view the remainder
of the dialog box.
Always use the point of the stylus for tapping or making strokes on the display. Never use an actual pen, pencil, sharp or
abrasive object to write on the touch screen.
An extra or replacement stylus may be ordered.
A replaceable touch screen protective film is available when the Thor VM1 is used in an abrasive environment. Contact
Technical Assistance for availability.
