Popvideo: The screen is infinitely large

If you want to share videos or photos in your iphone, but you're always limited by the size of your screen, pop video is the projector you need.　　Wen |CBN reporter Zheng More and more traditional instruments are becoming portable mobile terminals into our pockets, such as projectors. Recently, the United States Spotlight Technology (Micron Marvell) company launched a micro-projector called pop video, which is designed for the iOS system is an external device. The size of the iphone is about the same, thicker, but it's only 97 grams.　　At its bottom there is a 30-pin dock jack that can pop up, and when you connect to it, by controlling the app of pop video, the gadget can project images, videos, web pages, and so on around the Jing Yiping surface. Spotlight Technology claims the miniature projector has a projection range of 5 inches to 50 inches, and the app is designed to act as a projector controller, adjusting the parameters of contrast, contrast, brightness, and sharpness.　　At the same time, Spotlight technology has adopted a visual enhancement engine (VEE) developed by QuickLogic, a company based on the production of low-power semiconductors and software tools.　　Vee technology can better adapt to the surrounding light environment, adjust the view effect-the best thing is, even a blurry picture, can also be adjusted to make it clear. Some of the current evaluations suggest that this is a bit too optimistic. In the trial, the projection works well when it is shown as 5 inches and the light is moderate. But when the range is growing, it's also slipping, and if you still want to keep good results, unless you're in a very dark room.　　Also, it's hard to be precise when focusing. Considering this is only a miniature projector, its luminous flux is only 5 lumens, although Spotlight stressed that the actual effective output is 10 lumens, but compared to our common type of projector, this data will be more than 2000 lumens, the highest or even 15000 lumens.　　Another difference from a conventional projector is that the miniature projector now usually uses an LED light source, which saves space and prolongs service life compared to conventional bulbs. Compared with previous similar products, PoP video resolution has reached the QHD level of 960x540, at present, is the highest. Just for those who are accustomed to the iphone's Retina screen, the gap may be hard to satisfy.　　But think about the occasions you would use it-the display in the conference room, the sharing of friends at parties, and the projection of video to the ceiling before going to bed. Now the product has been booked on its official web site and currently supports only the iphone 4S, IPhone4 and the third and fourth generation ipod touch. Can play 2 hours in full power stateVideo, the built-in lithium battery takes 4 hours at a time.　　And its biggest advantage is its price, 99 U.S. dollars (about 623 yuan), which is cheaper than the previous similar products half or more. Many Apple accessories manufacturers have introduced similar products, Phonesuit company has launched the mini Pro, while another manufacturer Iprojector has launched a projector with the same name, they have 640x480 resolution, the projection of the largest image can reach 70 inches. and BenQ (Weibo), Brookstone and other companies, have developed a micro-projector for mobile phones.　　Samsung, the company's biggest competitor, will launch a galaxy beam phone this month, which will have a 15-lumen projector built directly into it. This is not the first projection cell phone, Fujitsu has tried earlier-they all benefit from a Texas instrumentation (TI), a system called DLP (Digital Light procession) chip. And pop video uses the current miniature projection inside the other chip technology LCoS (silicon-based lcd, Liquid Crystal on Silicon), do not forget that spotlight is still the world's largest manufacturer of semiconductor storage and imaging products.　　Compared to DLP only ti A, LCoS current camp is even larger. The advantage of this product is portability, price and projection time to achieve a consumer satisfaction balance. Competition is continuing, but it is not surprising that the projector will become standard for mobile phones soon.
