Mobile phones can be equipped with the latest accessories pocket of projection

Finland's UpstreamEngineering company is developing a LED (light emitting diode) projection system, this prototype projector light engine only Matchbox, later manufactured projector will only mobile phone are larger, equivalent to a mini digital video recorder.

Ultra-small projector

Due to the small size and relatively cheap, this system will be in the MP3 player, mobile phone or other portable electronic products installation projector, but the price just a few dollars.

To watch the video or picture without everyone with a mobile phone, simply place the image (video) projected onto a wall can; although the brightness of the picture than standard projector, however in the mobile phone and display pictures to MP from screen size limit.

Size reduction from the Upstream company invention of light will be LED to thousands of small beam form project to monitor technology. Light a candle or LED is issued, all have the scattering of natural attributes. Upstream companies have already built a complex of micro-optical systems, collecting light near the light and focus to an intended target, this is referred to as the "photon vacuum" (photonvacuum) optical system, just like a shell-like surround LED.

LED projectors are liable to become very cheap, because Upstream companies of optical system does not require a lot of parts, the shell is made of plastic injection molding production line, the basic amount of the photon vacuum system in the sale may be after 10 dollars.

Current Upstream product lighting performance also failed to achieve commercial production levels, although the company believes that this technology can reach 70-80% utilization of light, if you can reach 60% of the light utilization can cause cell phone manufacturers. Although many of the basic design and lighting systems of production problems resolved, but needs to improve the quality and performance.

A major challenge is the production of polycarbonate shell mold, its pattern is used in the production of chips--lithography technology. Mold production is also not very satisfied, but Upstream companies hope next year to produce a commercial production value of the engine.
