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 f
or information on the operation of the 
display in freezer and outdoor environments.
