It’s rumored that 3M is currently developing a second generation micro projector module that will increase optical efficiency while maintaining a VGA resolution of 640 x 480.  This new micro projector module may be employed in 3M’s second generation mobile projector.

While specifications are not confirmed, the micro projector engine is supposed to have a VGA resolution, capable of 15 lumens, and power consumption of less than 2.5 watts.   If this is true, this truly takes us one step closer to cell phone integration as this is almost 6 lumens per watt, an improvement over AAXA’s 3.5 lumen per watt yield and Dell’s 1.5 lumen per watt yield on their micro and mobile  projectors respectively.
