2009 Micro
4 years ago, when the pico projectors
was a concept of time, many industry its luminous efficiency, cost control has doubts. 4 years later, micro-projection has been quietly rising in a time when people unknowingly grow. Now, not only has the mini-projector LCD (liquid crystal), DLP (Digital Light Processing Technology , First video signal through digital processing after the projection out), LCOS (liquid crystal on silicon) and MEMS (microelectromechanical systems) and other mature technology base, and gradually to the consumer market penetration.
Micro-projector end product blowout
Recent years, micro-projection of the growth rate is very rapid. In the micro- Projector Key components, including DjinDisplay, MicroPrecision, Microvision, Texas Instruments (TI) and other companies have already embarked on MEMS micro-lens reflex system development, and has R & D results published.
And from October 2008 to January 2009, the end product is a micro-projection blowout period.
10 21, Optoma Published weight of 80 grams, a resolution of 480 × 320 of the PK-101 miniature projector after the 3M Micro-projector MPro110 official listed in Hong Kong, which uses LCOS projection technology, with 640 × 480 resolution; RedShift introduced a portable projector, model PPR4803; Ai Puke introduced PicoCube mini-projector, the size of machine almost the size of an ordinary egg; Scitec company unveiled its mini-projectors VLP-100; Aiptek pocket projector PocketCinemaV10 officially listed.
Moreover, the United States in 2009, CES Show, Samsung showcased MBP200 projector mobile phone, its body is equipped with a 2.2-inch screen, and supports a maximum capacity of 16GB of Storage Card expansion, with T-DMB digital multimedia television, stereo Bluetooth, video input capabilities. LogicWireless display a company mobile phone with projection function LogicBolt, LogicBolt supports GSM / GPRS network, but also support the CDMA network, the aircraft is also equipped with a 3 million pixel Camera , Support MP3, MP4 and play AVI file formats, in addition to LogicBolt is also a delegate from the LogicWireless Shenzhen, China Cooperation OEM mobile phone manufacturers produced the current contract price of the machine is 100 dollars, equivalent to about RMB 700 yuan.
Mitsubishi Digital Electronics America’s Display Products Group product manager WayneKozuki told reporters: “Very often, all need to book meeting rooms, and meeting materials and the corresponding need to bring their own hardware. The micro-projection is not only more convenient to carry and Rapid cooling also reduces the waiting time, greatly enhance the work efficiency. ”
Technical outlook depends on the background Light source
In dozens of products have been listed, reporters found that most micro-projector with DLP and LCOS technologies are.
Kwong King Technology Dr. Yang Weiliang in the “China Electronics News” interview, said: “LCOS, and DLP with the main reason is that the two technologies of power, simple structure.”
DLP, Texas Instruments is the manufacturer of its representatives. In October 2007, Texas Instruments introduced the latest generation of micro-DLP projector prototype, it can be built into 1cm thin phones. Now collaborate with vendors including Samsung, LG, Optoma, alcoa, Mellon, NEC, BenQ, Dreamarcade, Sypro, and Yang Ming optics.
LCOS is concerned, on behalf of many manufacturers, the key to 3M, Li Jing-based optical and other enterprises.
