Small Projectors are Changing Our Life
The projector will take all kinds of audio input, allowing users to directly through the norms of feed video player iPhones terminal connector, two including, allow connectivity RCA and VGA cable directly or notebook computer, the most standard audio and video equipment resources, such as DVD players, video, etc. Users can input at any time with all kinds of input source "button.
Tired of lifting heavy projection to rack, ok? M109S pocket projector for dell, you will significantly reduce your luggage operation period, still can display images in your next presentation.
People had considered it thinks micro projector is an ever make tinier - accessories and more data and media, we have in them. The company has always been and attempts to establish a miniature projector, you can put your bag, even mobile phones or computers will be even better.

How Does Projector Work?
Now many of the manufacturers have announced or are shipping their first pocket projector either as stand-alone units or integrated into other handheld devices. Like a laptop, a digital camera, a cell phone and so on. You can expect to find some of these models under other names as private labeling is a common practice. Pocket projectors are also refer to be pico projector, small projector, micro projector and so on.
Picos use LEDs as their light source, which means the light source will outlive the projector's useful life and provide efficient use of your battery power. The display technology will either be DLP or LCoS and you might consider looking at both technologies to see if you have a preference. Laser technology is also in development, but to our knowledge no laser units are shipping. So there are also some laser technology in the market which can be used to different occasion like the party.
Since projectors tend to get less bright the smaller you make them, it should come as no surprise that mini projectors are dimmer than their bigger cousins. As the new technology are difficult to be intergrated into it, small projectors, like cell phone projectors is lacking of contrast and brightness.
Micro projector will migrate into the devices they attach to. This should happen quickly as it is a natural evolution that eliminates cables, reduces cost and greatly enhances usefulness. The driving factor will be cost, power management, space considerations and market appeal. In other words, for your iPod to become an iProjector, it will need to maintain its look, feel and usefulness and offer a benefit that justifies the cost increment
So with the development of science and technology, we look forward the new features and high definition can be intergrated into the small projector, by then, mini projectors and cell phone projector will hold a great market and the popularity will be increased rapidly.

History of Projectors

In 1420 the First Projector Was Created
Johannes de Fontana , envisioned in a drawing with the first idea of projecting an image on a surface In 1420. It was a sketch of a monk holding a lantern. In the side of the lantern, there was a small translucent window had an image of a devil holding a lance. The image, probably drawn on a thin sheet of bone, was projected onto a wall by the flame in the lantern. However without a lens, the image on the wall were very blurry.
The first overhead projector was used for police identification work. It adopred a glassine paper roll over a 9-inch stage allowing facial characteristics to be rolled across the stage. The U.S. Army in 1945 was the first to use it in quantity for training as World War II wound down. Then It was began to be widely used in businesses and schools in the late 1950s and early 1960s.
Gradually the Projector Was Improved
The magic lantern of those days looked like a kerosene-fired slide projector. The lantern slides were large, bulky, complex objects, made of glass, paint, wood and metal. Some had built-in mechanical features, such as pulleys and winches, so the lantern’s projected images could be given a very crude version of animation. Some slides could even project complex, constantly-moving screen displays.
The Multimedia Projector Answered the Call
In the mid 1990s, with the hardworking of scientists and engineers, new technology was created that eventually led to the first multimedia projector. The newest technology of the day was digital processing. Applying digital principals to projectors permited the development of digital light processing (DLP). DLP technology, created by Texas Instruments, takes the reflective power of more than 1.3 million microscopic mirrors, and hinges them on a digital micromirror device (DMD) chip. The first DLP projectors produced grainy images, but the technology has greatly improved from then on, and now the brightest images ever can be manufactured in a multimedia machine.
Multimedia Projectors’ Future Seems Bright
Multimedia projectors will be injected with so many technological advancements. And considering let it can be carried everywhere. Right now, there’s no end in sight, at least not in the near future. So what will be coming next?
As the wireless age creeps in, projectors won’t have those bulky VGA cables connecting the projector to your laptop. And, with the onset of PDAs, you’ll soon be able to manage your entire presentation in the palm of your hand. If you use multimedia projectors now, just think of the possibilities then!
Now mini projectors and small projectors are coming out from the market, according to the requirement of the customers, manufactures are trying their best to develop more new and attractive products to cater to the requirement of customers, and also the pocket projector will be a trend in the near future!

Features of Pico Projector
Pico projector is ideally sized for making presentations of on-the-go business or casual video sharing with friends without the screen size limitations of a mobile handheld device. Importantly, this micro projector will connect with a wide range of mobile devices , such as iPhone, Camcorders, iPod, iTouch, DVD Players, DV-Cams and Digital Cameras .
Those projector is positioned between 8 to 189 inches (0.20 to 4.8 m) from the screen. Of course as the low lumens rating compared to a conventional projector, the brightness of the projected image for the largest image sizes is crucially dependent on the ambient light level. Generally, the product is designed to use in lower light levels with a smaller image size than conventional meeting room projectors. So it is easy for customers to carry this gadget everywhere at any time.
A good pico projector can have a good contrast ratio (full on / full off) of 2,000:1 which contributes strongly to picture quality as does the DLP projection system to color reproduction. Due to the projectors size there is no keystone correction so, it must be manually aligned square to the projection surface. There is a manual focus ring.
Pico projectors have made our life be more easier, and confortable, it has saved a lot of time and money. Now you can only need to take one or two hundred US dollars then you can buy a mini projetor, you may choose a best one as your requirement.
