5.3.1.1 Brightness
Brightness can be adjusted in the range between 0 and 100.
LCD panel screens are lit with built-in fluorescent tubes above, beside and sometimes behind the LCD (Cold Cath-
ode Fluorescent Lamp, CCFL). This light is adjusted using the Brightness setting.
How brightness is perceived depends on the environment and on the content being viewed, which means that
switching a source and/or the ambient light could require re-adjustment of brightness.
H
ow bright a pixel is perceived depends on both, brightness setting and contrast setting: bright-
ness setting affects all levels from white to black at once. Contrast setting affects all but black.

ratio.
