Curious About Projector Basics

[mtrycrafts]

I'm not so sure about that mtry. Please correct me or enlighten me where my knowledge is lacking:

LCDs use their max power rating due to the backlight always being on.

Plasmas rarely ever use their max power rating because no one watches a bright, white, blazing screen all day.

The power consumption is actually more comparable than not.

I think someone else was mentioning how many plasmas had the energy efficient label vs the lcd panels. The hottest set I've ever checked out was actually an LCD, a friend's Sharp. You can feel the heat with your body/face from a few feet away.

I checked the back of a number of plasma and lcd tvs and lcd had 1/2 the power rating on the back than the plasma, even a smaller plasma had a higher power rating on the back.

Plus, Consumer Reports had an article on this as well not sure of the issue. One way to find out is with a current meter to both

This is maximum power draw, not typical usage. I believe either Home Theater or Sound and Vision did a real world test of LCD vs. plasma for power consumption and their tests showed that the difference between the two technologies was neglible.

It is exactly as stated... A LCD draws 100% of lamp power 100% of the time. In comparison a white scene with a plasma draws 100% power, but a black scene draws very little current. The average is somewhere between the two, with a lean towards less power since most video is darker than it is lighter.

The results showed that LCD did still maintain an advantage, but it was nowhere near what had originally been believed to be.

Interestingly, because LCDs must charge a pixel to make it black, the darker an image the more power a LCD display will use.
