3.4 Touch Screen Display
3.4.1 TFT Monitor
The 8570 Vehicle-Mount Computer is equipped with a high-resolution colour
SVGA display, which supports the newest technology and enables full use of the
display both in graphics and in text mode. The TFT 30.7 cm (12.1 in.) display
provides a resolution of 800 pixels by 600 pixels and supports 256 colour mode.
The colour monitor is a thin film transistor (TFT), which uses a backlight for
viewing. The display is capable of operation in a full range of ambient lighting, from
direct sunlight to complete darkness. The display has a standard brightness of 500
NIT. Backlighting intensity should be adjusted for optimal readability. The display
incorporates a fixed, pre-set contrast. Colour intensity is a function of display
viewing angle and ambient light intensity. The screen has a 120-degree viewing
angle. If necessary, adjust computer angle and position for optimal colour and
character visibility.
Important: For 8570 Vehicle-Mount Computer Freezer/Extreme Temperature
units, please see page 35 for information on the operation of the
display in freezer and outdoor environments.
