4.1.1 Liquid Crystal Display
The Liquid Crystal Display (LCD) used in the Hirschmann ECS PRS 80 console is a wide temperature-
range graphic display with transflective characteristics that give it a high visibility in sunlight and during
backlit night operation. Due to the nature of any LCD, it works on the principle of polarization of light. It
should be noted that dual polarizations that are at a certain angle to each other can reduce the
amount of light up to completely eliminating it if that angle becomes perpendicular. This can have
significance if the operator is wearing polarized sunglasses that happen to be perpendicularly
polarized in relation to the LCD’s polarization. In this rare case, the operator has to work without
sunglasses or find different sunglasses that do not have this characteristic, in order to avoid having the
visibility of the display impaired.
The LCD contains an automatic temperature compensation that will adjust the LCD’s contrast
according to the surrounding temperature.
