Does black pixels on an LCD screen use less power than white?

Digital Signage Blog

15 years ago

Since quite a number of companies are focusing on being “green” and environmentally friendly, I was wondering whether there was a way to reduce the amount of power an LCD screen uses based on the colour of the content being displayed.

So here’s an interesting question for those techies out there who may be able to shed some light into this question. Moving forward, if black does use less power, the content providers should focus on using this black rather than the others bright colours and screen manufacturers should develop a technology to disable pixels use based on colour.

Does black pixels on an LCD screen use less power than white?
