This prerogative leads to a difference in display ( while main-
taining the same contrast and temperature) when the obser-
vers are at different distances with respect to the terminal.

pixels (always on) or black (always off). This phenomenon can
be visible or invisible to the user depending on the colour
displayed.
Touch screen
The touch screen is activated by applying a force equal to
200g indifferently to the use of a pen or finger.
A Peripheral Area of the touch screen exists that must never
be stressed, especially with pointed objects (pens etc.). The
glass in this area is very sensitive to pressing and is subject to
breakage.
