Micro projection technology set off a new revolution in portable products

In recent years, mobile phone and TV with the trend, has become popular trend of mobile TV, mobile phone in the market for multifunctional constant request, the mobile phone manufacturers have joined the planning projection function in the mobile phone, mobile phone to create a more diverse application.

The key of portable projection technology LED light source and laser light source

At present, the mobile phone manufacturers have a high degree of interest in the projection function of the mobile phone, mainly due to the development trend of the information system. The integration of the projection function of mobile phone, will be able to provide users with large screen video, get visual enjoyment, but also for business presentation purposes, greatly expanded the scope of application of mobile phone.

There will be another reason for this change is that the existing projector products have been Pro market saturation of the market, the annual sales growth rate is limited; however, the mobile phone application, more and more multimedia functions, such as the MP3 music player, digital camera, digital camera... Etc, have been gradually integrated into the mobile phone; mobile phone but limited volume, greatly limits the size of display space, therefore, how to make the multimedia mobile phone can play breakthrough volume limit, is one of the key to mobile phone sales jumped again.

Coupled with the current mobile phone market has reached 1 billion scale, for mobile phone manufacturers, projector manufacturers, such a huge market opportunity, is clearly in front of the fat, for what reason.

Related industry to actively develop projection function mobile phone

Currently on the market with a very small number of mobile phone projection function, and the price of about 200 thousand yen, can only be regarded as a test of the market price of high water luxury. Therefore, less than 100 thousand yen, even lower than the price of 10 thousand yen projection mobile phone, it is the industry expectations, therefore, relevant component manufacturers have plans to price setting mechanism of micro projection in the tens of thousands of yen, even in the future plan spanning less than 10 thousand yen price threshold.

The key component of micro projector parts, including DjinDisplay, MicroPrecision, Microvision, TI (TI), UpstreamEngineering industry, already embarked on a micro mirror microelectromechanical (MEMS) development, the research results published; and the micro projecting mechanism part, Nokia, Motorola, Samsung, Canon and other industry. It has successively developed the thickness of only a few millimeters, the micro projection mechanism with dimensions of only a few centimeters of mobile phone.

On the other hand, in the light source part, also related to the development of the industry gradually developed by LED or laser diode to replace the traditional light source, improve the mobile phone projection brightness, so the projection quality can meet the basic requirements of image quality. Caption: Motorola, now include Nokia, Samsung, Canon and so on in the industry, has successively developed the thickness of only a few millimeters, the micro projection mechanism for only a few centimeters the size of mobile phone, to seize the emerging market actively.

Key parts of micro machine have been breakthrough

In the exhibition in 2007, the global industry has been showing its micro projection machine research and development achievements, such as the January 2007 Garth held in Las 2007InternationalCES, Microvision shows the development of the micro projector, and related technology. Micro projector Microvision display, using semiconductor laser, the light source can be controlled in the range of 40 * 25 * 8mm, and the ability of image resolution up to 800 x 480 pixels WVGA display.

Microvision believes that the main demands of the target in 2007 micro projection mobile phone, is a built-in micro projection function, the portable electronic equipment priced at 200 thousand yen, 100 thousand yen price to replace the traditional PC as the processing center and display the future data center, and the goal is to import the portable micro projection mechanism to the mobile phone, PDA and all of the digital camera.

Technology development strategy of Microvision is embedded by 2 axis laser scanner, MEMS mini projector, cooperation at present Microvision and 2 related technology industry, to achieve production target in 2008, plans to develop a blueprint. As for the price, Microvision hopes to be built in the projector structure in the phone, the overall price of the phone is maintained at $400~500.

In fact, the application of ultra small projection technology, is not only a mobile phone, Microvision also plans to extend to the micro projection technology such as iPod or PSP portable player, portable game machine products, achieved through a simple interface connection, can with the larger screen to see iPodMovie or PSP image.

Part of the light source, Microvision uses the Novalux produced by the semiconductor laser source NECSEL, luminous flux is about 10~15lm. The main technical features are small size, low power consumption, low cost and wide color gamut. Due to the use of laser light source, even if the image is projected onto the curved object, the whole picture can be displayed with an accurate image. Caption: Microvision development concept is that the use of 2 axis MEMS scanner and laser light source embedded ultra small projector, in order to achieve in 2008 to achieve the goal of planning and development blueprint.

DLP has become the mainstream of micro projector technology

In the projection of the key components of the part, with quite a number of technical specialist
