Thor VM1 with Microsoft Windows Embedded Standard 2009 User Guide 43
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.
Touch Screen Defroster
Extended temperature versions of the Thor VM1 contain a touch screen defroster. The
touch screen defroster can be disabled when not needed via the Screen Control panel.
The defroster trip point is configurable. The defroster is always disabled when the
device is operating from UPS battery power.
Screen Blanking
Screen blanking (blackout) can be enabled when the vehicle is in motion. See Screen
Blanking for hardware setup and Screen Control for software setup to enable screen
blanking. Once screen blanking is enabled, the display is blanked out any time when the
cable sends the signal that the vehicle is in motion. If the cable is removed, screen
blanking is disabled and the display remains on.
