How do you light a reflective screen? I'd go with a clip on light, myself, but the only real way to integrate a light source would be to embed a front light. That's what Qualcomm did with their new Mirasol demo. And this is indeed their new demo; it's the first time it's been shown off.
I wish I were going to SID Display Week next week; they promised to have one with an ambient light sensor. This one had a pair of buttons on the back to increase and decrease the brightness.
The bad news is that the finished products won't hit the market until fall. Yep, it's delayed again, darnit.
And the really great news is that Qualcomm offered to fly me to Taiwan next time that they have a sponsored trip. (I can feel the waves of jealousy from here.) I'm definitely going to take them up on it; there's no way I could afford it otherwise.
