NTT DoCoMo demoed a prototype mobile phone at CEATEC JAPAN 2008 that can be used as a projector. Based on an existing handset, DoCoMo integrated an ultra-small projector into the base so the mobile phone is too fat to be practical.
The projector uses red, green and blue LEDs for the light source and is equipped with the Pico’s DPL chipset / DMD (digital micromirror device) downsized for mobile use.
As you can imagine the projector is not a powerhouse with a luminance of only 7.5lm and pixel count of 480 × 320 producing a 20-inch image from a distance of about 80cm. The power consumption is about 3W yielding only 15 to 20 minutes with the prototype. DoCoMo says a commercialized version is at least 3 years away with an aim of having at least 100 minutes run time on batteries.
