Konica Minolta developing tiny color projector

konica-minoltaKonica Minolta has developed what sounds like it’s one of the smallest projectors around today. Measuring just 20×40x7mm, the projector is reportedly about as small as a USB stick and needs less than 1W of power.

The projector can project 20-inch color images in XGA resolution when positioned 50 to 60cm away from the screen. Red, green and blue lasers are used as light sources. Piezoelectric elements are used to vibrate micro mirrors (2mm in diameter) Konica Minolta used instead of a projector lens at 30KHz. The lasers are being shot on these mirrors, which move both vertically and horizontally.


Konica Minolta apparently aims at commercializing the technology within the next two to three years.
