<br> <br> 1. What is the projector can be used to do? Projector, blunt is a video display devices, like our home usual television, computer monitor, etc. It may have a friend ask, since all have a television ., monitor, then why are you still using a projector? this question asked well, this just leads to the projector, which distinguish it from other image display device exists: projection function provides other display devices incomparable big picture, 30-35 inches can be .easily achieved, as long as your room is so great. And like the larger TV screen when a few current plasma flat panel TV, mainstream can achieve 42-60 inch screen, while the dimensions for the projector, it is too easy to implement. .Projector is the advantage of relying on big screen features, widely used by the user, including schools, government institutions, enterprises, troops, families, and so on a wide range of industries and application areas. Second, the classification of products in the projector .if you want to break down the projector's applications, it is very complex, but the press industry practice, typically the projector into three broad categories: education, business and household sectors. Which education projection market is China's largest projector market, mainly due to the .trend of Chinese education; and as the business market, an increasing number of small and medium-sized enterprises, their business projector needs let business projector market has become China's second largest projection market, like many high-end engineering projector or industry applications projector we .are by default into the ranks of the business projectors; finally home projector market, this market in China is still very small, the industry did not push, consumer habits and consumption levels and other factors are influencing the popularity of home projector in China. But .the voice of the industry as a whole showed that China's household projector market potential is very large, one day will be like abroad almost as popular as the TV set. The projector can also press the core display technology to category, this method can be compared .to your PC using the Intel or AMD CPU, the projector also has its different parts of the core display. The present global context, including the following in the projection display technology: LCD, DLP, LCOS, SXRD, LASER and GLV. As ordinary .consumers, as long as attention LCD and DLP technology. Because the two technologies is the leading two technologies, brand, market adoption of these two technologies of projectors. While holding both technologies than LCD projector market share compared to DLP projector is also bigger. After .all, LCD projector has a long history of development and production, and the DLP is subsequently appear in projection technology, but because it is a different principle of LCD technology, in many areas to provide higher than LCD projector, of course, it also has .to go beyond the LCD projector. But because of the DMD chip DLP has an exclusive technology of United States TI company adopted an active Union global projector manufacturers, including actively give technical support with a variety of resources, so that more and more manufacturers are willing .to take the projector DLP technology to produce projectors, DLP technology allowing visibility quickly became popular, and DLP projector in the global market share is rapidly increasing. Projector correctly used do not use the projector's friends to pay special attention to it, the projector is not .like a TV set, you open the machine, do not cares, TV opportunities natural provides gives you a best picture, while the projector is not, if your projector per use are different, then you need each time you use the projector to be regulated ., including screen trapezoid correction, picture zoom focus, brightness contrast resolution and color, and so on. You may have friends may ask, if the projector is in one place, it is not always transferred? Yes, but not all of the projector is .able to realize that this requires the projector must have a "save the parameter settings / use the last saved settings" in this function, in this case, the projector will each time you press your setting to turn on display. In particular, to say .the projector off, unlike TV, the TV you can even shutdown button is not pressed directly unplugging the power shutdown, and the projector is different, in order not to damage the projector, you must follow the proper shutdown procedure, first press the off button .shutdown, and then enter the projector, and then fan cooling stage we need to wait until the cooling is completed, fans had to pull the power cord. While I may have also had better not make projector closely encapsulated, try to maximize the internal heat .are dispersed to pack as well. Practical function function it is not practical to for specific application areas, education projectors typically require cooling ability strong, dustproof features strong, rich interfaces to compatible more peripherals, video stills and local amplification function, a longer bulb life ., outstanding anti-theft feature, network projection capabilities, pointer functionality; business projection is fast, so the regulate for power on, the screen and shutdown speed is required, it is best to have a power failure protection, another business for a variety of .convenient image preset mode is required, there are also pictures of still and local amplification function, card vote projection feature, short features, such as wireless projection function; household projector is the most attention to quality, so it is usually more requirements manufacturers able to .machine factory provides a very good picture of the initial state is set to the user. If the factory settings do not so good, that user will need the projector provides better acquired color adjustment, to easily adjust your desired color and picture quality performance, and .so on. Additional setup for home projector is very important, now generally require home projector equipped with a lens shift function, this projector in a difficult environment installation is very important. Finally, it is best to have a backlit remote control function, that is ., the key will glow in the dark, for users in a darker environment watch movies while wanted temporary control remote control is very user-friendly. <br> Third, the projector market in a global market development for projector, Global projector sales every year .to 35% faster growth, greater China projector market is higher than 40% growth in its market potential is enormous. Authoritative research institutions related data show: Chinese projector market in 2005, the total sales volume of more than 30 million units, including education industry .procurement more concentrated, accounted for the entire market share of 55%, and in 2006, education projection product sales are expected to be a stable rate of growth. Commercial projector occupies about 30% market share. But household projector market in about 1%. .It is China projector market such a high growth rate and so much mining space, attracting domestic and foreign more than 50 brands of fierce market competition, China projector is warlordism. Brand and market share of international authority research institutions CBIResearch believes that China projector market so .many brands by geographical region and features can be divided into three main camp: day camp, European and American manufacturers camp and local Chinese manufacturers and manufacturers. These three camps: Epson, Toshiba, Sony, NEC, Panasonic, Sanyo, Hitachi, sharp, .Mitsubishi, Japan firms ranked China projector market share in the first place, the overall sales volume of the overall market 66.7%; to ASK, is rich in Visual, Barco, Visual, DELL, HP, IBM, ViewSonic, auto code, such as .European and American manufacturers 3M ranked second, sales of the overall city arena; 20.0% to BenQ, Lenovo, AO, Morningstar, Seattle, 3T, China's domestic manufacturers third, sales overall market 12.0%. With a single brand, Epson also occupy the .first position in the global market share of no. 1 market share. According to many years of observation, occupy the market share of China TOP10 finalist brand is probably: Epson, Toshiba, BenQ, Sony, NEC, sharp, Sanyo, Hitachi, Panasonic ., Mitsubishi. Channel projector unlike appliances that can include GOME in professional electronics chain or like better and more, Top100, vanguard, and other such ordinary supermarkets sell in, and the projector is unable to achieve this. Projector sales the most traditional and most common .way is through the channel. Projector manufacturers typically take two channels, one is in China only a general agent, and then from the lower total generation is responsible for the entire channel network of laying, like Hitachi projector is Honghe total generation, Toshiba projector is .shenma total generation, etc. While the other is by the manufacturers directly in several districts of the country set regional total generation, ie the so-called flat channel management. Like the BenQ, Sony and Epson have taken this approach. Price is the price .of a projector usually has two types of channel pricing, media offer, usually channel price than media quotes are much lower, closer to the cost price of the projector. Therefore, if you know the business as far as possible with the projector he picked channels .price is very affordable. Projector price to high-end engineering models to price maximum, up to hundreds of thousands, or tens. And business education projector prices simply and brightness and resolution have a direct relationship, generally reflected 4000 lumens brightness and XGA resolution around .the projector price base more than 20 000. And about 3000 lumens brightness and XGA-resolution projectors prices probably in 1-2 million. And 2500 lumens brightness and XGA-resolution projectors prices have dropped to $ 89 thousand company can buy. If you choose ., regardless of education or business machines are generally mainstream 2500 meters or higher brightness. But household projector, on the contrary, demand for brightness is not high, usually for about as long as the 1200 lumens, but for contrast and resolution of pursuit in theory .is the higher the better. Now the mainstream of domestic machine resolution 720P, prices in 1-2.5 million. <br>.
