Normal transflective LCDs consume 1-2 mW/(cm*cm) (which means this new display would be 10 times as efficient, not 100 times, as the article claims). With this new display an A4 (630 cm*cm) would consume 100-130 mW, so if you drive this (5V?) display with 4 AAA batteries storing 800 mAh you have almost 4000 mWh (4*1.2V*800mAh), which translates to 30-40 hours. Hmm.. shouldn't it be more, considering I used to have these small LCD pocket games that ran with tiny batteries for months? What am I missing? Well, mW sounds more like it.

By next Summer the playing field should be even more crowded than it is now. Plastic Logic and Astak should both have touch screen offerings out and the 9 inch e-ink devices will go on sale. It's going to be an interesting year for display technology. Will this be anything more than an also ran...who knows? Wake me when he has a prototype device, pricing & software.
