As I look to my futre, I see myself owning a projector or LCD/PLASMA widescreen display. My interests are minimal power consumption and ease of use for both film (SVHS/VHS/LD and DVD) and for TV.


What are the most efficient large screen, widescreen (1.78-1.85:1) technologies out there? Are projectors super power hungry? Are LCD's the most efficient? LCD displays or projectors? Plasma?


I ask this because I though the most convenient thing for TV and movies would be to have a conventional TV and have a draw down screen that just comes down right in front of the TV and use a line-doubler and projector for movies. But then I thought LCD displays are the least power hungry display devices.


So what are the least power hungry displays? (comparing similar or equal sizes of course).

Digital projectors are the most power efficient. 130-160 watts gets you 60-100' diagonal screen. In addition to this, you would extinguish room lighting which would actually mean the projector is a net win, energy wise.

Gary,


Not all digital projectors are created equal. My D-ILA draws 650 watts in continuous operation and much more than that during start-up.


I've recently been researching the next generation of flat-panel displays based on OLED (Organic Light Emitting Diodes) and the polymer OLEDs used are still in development yet already produce over 3 lumens per watt. A factor of ten in efficiency increase is likely. By the time they are ready for prime-time (5 years), even a 100" display would be possible and still only draw 100 watts. Something to look forward to. Their relative lack of complexity in manufacture should also mean cheap relative to flat-panels based on LCD or Plasma.

I should have guessed the LED would be in the mix for future products. I have already seen and held in my hand an LED light bulb that gives out as much light as a 60 watt bulb, but it only draws, get this, .35 watts! Yep.


That is interesting. I should look into the various areas of the research technology. I hope that the electronics industry takes the energy problems of the world seriously and continues to increase the efficiencies of electronics products of all kinds.
