environmental concern in this case is not about how much energy those frames draw, it's about the impact of the production. LCD monitor does prove to have better energy efficiency than CRT monitor but the CO2 emission of the production of OLED, LCD screens is far worse. it's the same as other energy resource. making solar cell panel has enormous CO2 emission that some countries are considering moving back to nuclear power which the construction process and running life circle emit smaller amount of CO2 (funny, isn't it, but that's true). bio fuel may drive the price of food. Again, those are all about the impact of the productions

Paper pictures use more chemicals to produce, ergo more pollution. LCD pannels are GREEN! THINK OF THE CHILDREN!

Please...

Please, please, please, enough with global warming already! How much power does a digital frame draw, anyway? One watt, two maybe?

Global warming and other theories aside, I'm all for reducing power consumption and finding cleaner sources of energy, but this is getting really ridiculous. Reducing your car's power consumtion by 20% and its oil consumption by 30~40% or more thanks to hybrid solutions is great, but come on, bitching about digital photo frames? Seriously?

Not on this account, I mean:

LCD-based photo frames are not long for this world, I believe.

Google "color epaper", when you have time.

Digital photo frames often contain the worst quality panels out there. They're made of the "off-cuts" of the LCD manufacturing industry and image quality is far worse than on a humble photograph printed on a piece of card. I think these frames would be an ideal partner with OLED panels, since currently OLEDs are limited to small dimensions. The picture quality would be stunning, the power requirements minimised. It might also help to convince the average-Joe consumer that the vast majority of LCD displays are pretty awful to look at and that they should be demanding something better.

What happened with that high resolution electronic paper that only needed energy when it changes images?
Too expensive I guess.
