LED light source of micro display rear projection TV dilemma

Has always been regarded as the bottleneck problem of micro display rear projection TV development source life, has been solved. In this year's CES consumer electronics show, DLP RPTV containing the new LED light source technology Samsung and Akai launch, the industry saw the micro display rear projection TV source technology from the traditional UHP model LED light bulbs to changed. The DLP rear projection light source on the use of new technologies, whether it will further exacerbate its and rear projection allies 3LCD camp competition? Light source to solve the technical problems of the core, whether it will be the introduction of the entire rear projection market to another peak sales? Industry experts pointed out: Although the bottleneck pressure eased, but under the double pressure of flat-panel TV and traditional CRT TV market situation, projection embarrassing in the short term difficult to be improved.

To alleviate the bottleneck pressure temporarily

Micro display rear projection key problems, immediately attracted the attention of many consumers. In this regard, experts bluntly: the core problem solved, some other technical problems will be solved.

Chinese Video Industry Association, large screen projection display branch secretary Zhao Handing said: "the application of a new LED light source technology has a revolutionary impact on the entire micro display projection industry, this technology will radiate to the 3LCD and LCOS micro display projection products. The solution of the light source technology makes the upgrade of other components relatively simple."

In fact, digital TV and high-definition TV launched, pushing up the micro display rear projection TV market, improve the unit efficiency and cost, the size of the picture quality so low, micro display projection has more advantages, and the bottleneck problem of light source life, and increase the micro display back projection TV market competition.

Yang Xiaoyun, director of planning and Investigation Department of EPSON China, said: with the light source to solve the problem of life and high-definition TV hit, with many advantages of micro display rear projection sales will have a qualitative leap. At the same time, there will be more manufacturers to participate in the competition in the rear projection TV market."

3LCD: dynamic pressure >

In the face of the new DLP took the lead in "attack", the biggest impact is supposed to be the 3LCD alliance. It is understood that, as the largest manufacturer of DLP RPTV competitors, DLP new 3LCD camp of Samsung, Akai launched showing interest.

The use of LED new light source technology DLP products, the 3LCD camp, is also a good news. LED is a shared technology, DLP can be used, 3LCD can also be used." Yang Xiaoyun said in an interview with the China Electronics News reporter. But he also admitted: at present, EPSON LED light source technology products are still 'pocket portable' small screen based. Samsung, Akai launched a large screen DLP products using new LED light source technology is walking in front of the 3LCD. The application of LED technology to 3LCD is the driving force, the opportunity, not the pressure." As a supporter of the 3LCD camp, SONY related personnel also expressed the same view with EPSON.

In response to this situation, the industry expert analysis revealed that the light source life is the rear projection members DLP, 3LCD and LCOS common problems. In order to alleviate the pressure of rapid growth of flat-panel TV, DLP, 3LCD and LCOS only temporarily put aside internal competition, learn from each other in the light source technology, as soon as possible to get rid of the shackles of the key technology of the life of the light source and so on, in order to form the core competitiveness of the micro display projection.

LED technology to be improved

It is understood that Samsung, Akai launch new DLP to replace the traditional UHP lamp with LED light source, can make the life of the product from the original 6000 hours to 20 thousand hours, while maintaining a lasting brightness attenuation. Samsung said it will be the first time this year launched the first LED light source containing DLP digital high-definition tv.

And an expert of Shanghai LED Industry Association lamented to reporters: "at present, the LED technology is not mature, Samsung, Akai launched new products are just test only, the maturity of LED technology and popularization still has a long way to go. Moreover, the impact of product life expectancy of more than one indicator." Zhao Handing also pointed out: "mature LED light source technology can improve the life of the product to about 80 thousand hours, not just the current 20 thousand hours."

Engaged in the production of TI DLP (TI) stakeholders also told reporters, although the LED optical engine maintains the DLP technology advantage in speed, color update speed increased to 48 times the standard television system, but so far, the degree of realization of this technology is completely commercial as well as a long distance. The outlook is not optimistic

Although the core technical issues have been resolved to a certain extent, but does not mean that the micro display rear projection market rebound. The face of LCD, plasma off the tablet revolution, micro display rear projection is still full of thorns.

According to market research company deputy general manager Ye Ping revealed that in 2005 the micro display projection sales of about 45 thousand units, with 30 million years relative capacity China TV market sales, obviously embarrassed. The data also verified the micro display rear projection TV in difficult circumstances: the micro display projection projection only accounted for the entire market share of 13.42%, accounting for 86.58% of CRT rptv.

As one of the few domestic rear projection manufacturers, SKYWORTH also showed concern in this regard. Zhang Zhihua, vice president of SKYWORTH Digital Research Institute, told reporters: LED technology will certainly have a certain impact on the micro display rear projection, but the entire rear projection market atrophy serious, any new products are required for market entry. although
