摘要：

We have successfully designed the most compact mobile embedded pico projector system, with an optical module size of up to 2.1 cc (20.6 x 16.4 x 6.2 mm), compared with the liquid crystal on silicon (LCoS) based projector system, which has an engine size of < 10 cc. The most compact pico projector system, with a reduction in size of about 25%, can be obtained. It consists of a projected optical system based on field lens type with 0.2 nHD (640x360) digital micromirror device (DMD) panel and an illumination part of the 2 channel type with 2 in 1 LED source. It can be obtained the available display image size about 5-60 inches with uniformity over 70%, brightness 8 lm at LED power consumption 1 W and contrast ratio 1700:1 in the dark room.
