LED backlight technology is one of the most noteworthy new development direction of projection

After years of technology development and product marketing experience, the use of micro display projector product development is already quite mature in technology, projection products can be said to have a depth of many big screen US education, commerce and family entertainment display field, at present all kinds of specifications before the projector and back projector market, LCD, LCOS and DLP are the three main types of original micro display projection technology, in the ordinary civilian areas, its size is about 0.55 inches to 1.3 inches between the range.

The digital, networking and multimedia interconnection of the projection display technology have been realized. The core of the projection product includes the light source illumination system and the color separation processing

System, projection lens, image signal processing circuit, micro display device, etc.. In the display effect, the current projection products have been able to meet the needs of users.

Of course, the user is looking for the world without end products, users hope to get more compact and portable, easy to carry the best products for projection applications; and that more cost-effective products, not only the price of the product, and other parts of the bulb and the service life is also a very important part, after all the current price projection lamp not cheap;

In addition, as a projection product, the core of the display effect, of course, also need to be guaranteed in the application. These three major performance requirements, although the new products have been greatly improved, but the "bottleneck" is becoming more and more obvious, because this is closely related to projection optical system design, to get better products, there must be a newer and more practical technology and product application.

The LED light source technology, has been a good development and application, can be said to be one of the most noteworthy new direction of projection.

How to develop the LED light source projector on the market today

Application of LED light source projection products debut in front of the public, is held in May 2003 at the annual meeting of SID, with its pocket body caused a great response, however, was only a concept product. The real practical significance is the CES show in January 2005, five companies also exhibited a LED light source pocket projector, people began to consider the strengths and weaknesses of LED products in the application of projection light source. And after a year of technology and product development, January 2006 CES exhibition LED light source has become the highlight of June 2006, SID published a paper discussing the amount of LED light source, which marks a new stage in the development of LED.

Due to the importance of the results, the performance of LED light source in the past two years to improve, in terms of core performance, it has better luminous efficiency, more power, and improve the light angle and monochromatic light emitting performance, thereby improving the brightness of the unit. And the new products to achieve AC-DC dual-use, and improve thermal management, etc..

These developments enable the use of LED light source projection products in the application performance is more excellent, the performance of the product market development also provides a basis for the development of.

What are the advantages of LED light source projector technology

The application of LED light source, in the projector, the most important significance is to open up a new way for the fuselage miniaturization. Due to the small size of the LED light source, and has many advantages of display technology, it is more suitable for the development of compact projectors and even the original, so that the user's projection more portable and free".

LED is used for projection lighting, which not only increases the life, but also changes the structure of the projector, because of reducing the heat dissipation requirements, and shortening the optical path system, so the heat dissipation and noise have better performance.

At present, the main application of LED light source and integrated small projection original and portable minicomputer two projection products, integrated small projection original made independent models, with its main display devices such as mobile phone, digital camera, notebook computer integrated with micro battery, power supply, can the image projection about A4 or standard letter size the picture, easy to share with others. Pocket pocket projector is a complete independent model, compact and lightweight, one hand can easily pick up, easy to carry, can be placed in the package, the future direction of development is business applications. The utility model has the advantages that the utility model can be used for both AC and DC, the projection screen can be larger than 17 inches, and the brightness of the screen is between 15 and 200 lumens.

What are the use of LED light source projector on the market

LED light source projection products have also been the development of several generations, from the earliest MITSUBISHI and Samsung's "pocket" projection products, although the shape is impressive, but the light is not enough to support the normal use. Later, the appearance of the EPSON and BenQ products reflects more ingenious design, EPSON products are equipped with two big fan to improve the stability of product, and the BenQ LED projector and intelligent mobile phone use collocation, shaping the business image, but the practicality of these two products is "flattered", even it is difficult to see the prototype.

But just as "projector products LED third generations", including the new MITSUBISHI, Toshiba and LG to popularize products of personalized products, very good looking forward to people in the real application, improve the new LED projection brightness in the MITSUBISHI products on the basis of the previous generation, the picture shows.

The new Toshiba is more "product", the current domestic has been introduced, and the overall concept of "relatively well, with a professional backpack placed a special projection folding screen, can be opened using high gain, can complement the projection and brightness.
