Display Brightness

The brightness of an LCD display is the amount

of light emitted and is measured in nits or

candelas per square meter, which has units of

nits or cd/m2. Most commercial desktop

displays have a brightness of 200 to 300 nits. To

see a display in outdoor light requires a

brightness of about 700 nits or greater. Almost

all new LCD displays use some form of white or

RGB LED backlight.

Some of the brighter displays can have

a half-life of 20.000 hours or less.

Bright Idea: The brightness life of the display

can be dramaticallyincreased and burn-in can

be mitigated by allowing the screen saver to

dim and/or turn off the display when not in use.
