CRT and LCD

[IcemanJer]

I seem to remember that for a CRT monitor it takes more energy for it to display a brighter image as oppose to a desktop that is primarily dark colours, while for a LCD monitor it is the opposite (more work to show a dark image versus a bright image). Is this true? If so, why?

Maybe because LCDs use crystals and CRTs rely on electricity passing through color tubes.

To show a bright image the CRT has to fire it's Cathode Rays at the Screen in order to illuminate pixels and "shade" them.

An LCD has a permanent "back light" and the pixels and sub pixels impair the "backlight" in order for colour reproduction etc to take place.

"I think".

Hope this helps.

DOOPY's got it.

Sweet. Thanks.

Okay, so my next question is.. if an LCD monitor is continuously showing dark images, would that reduce the life of the monitor or is that a non-issue like the "image burn-in" effect with modern CRTs?

I think it's not an issue...
