Figure 2-11 MX3-CE Display
The MX3-CE Touch Screen Display is an LCD unit capable of supporting VGA graphics modes.
Display size is 640 x 240 pixels. The display covering is designed to resist stains. The touch
screen allows signature capture and touch input. A pen stylus is included. The touch screen
responds to an actuation force (touch) of 4 oz. of pressure (or greater).
There are three types of displays available: transflective greyscale monochrome; transmissive
color and transflective color. The transmissive color display is optimized for indoor lighting. It
cannot be used without the backlight. The transflective monochrome and color display are
optimized for outdoor use but may also be used indoors. The monochrome display has an
electroluminescent backlight. The color displays have a CCFL (Cold-Cathode Fluorescent
Lighting) backlight.
The transflective display appears to have a greenish hue when the display is blanked. The
transmissive display appears black when the display is blanked.
The choice between font sizes is made in the Control Panel option "Display | Appearance." Font
size selection may be overridden by a user supplied application.
The display is automatically turned off when the MX3-CE enters the Suspend state, Critical
Suspend or the Display Blanking timer expires (Display Blanking default is 15 seconds).
Display and Display Backlight Timer
When the Display Blanking timer expires the display is turned off. The default value for the
battery power timer is 15 seconds. The default value for the external power timer is 2 minutes.
When the Display Backlight timer expires the transflective screen display backlights are turned
off, a transmissive screen is dimmed. The default value for the battery power timer is 3 seconds.
The default value for the external power timer is 2 minutes.
Both values can be adjusted using the Control Panel option "Display | Backlight" or "Display |
Blanking". Any of the following will wake the display and display backlight:
Any key on the keypad COM1 activity
Stylus touch on the touch screen COM2 activity
Power button tap COM3 activity
PC card activity USB connection
External device connection (e.g. cradle) Scanner activity
When the display wakes up, the Display Blanking and Backlight timers will begin the countdown
again. When any of the above events occurs prior to the timers expiring, the timers start the
countdown again.
