Luo Dongmiao: MD back energy-saving and environmental advantages projector – projectors, office equipment – office supplies industry

Annual consumer electronics China “held in Beijing Hotel, the new majority.

China Video Industry Association of large screen projection branch of the Luo Dongmiao senior engineer in the “sub-forum 2: New Projections of China opportunity” to do, entitled “MD back Projector Energy saving and environmental advantages, “the report.

Luo Dongmiao: Good afternoon, just key components of teachers for the localization of the optical engine are introduced, which in fact is a positive projection, rear projection Ye Hao, laid the foundation.

I do today to speak to about personal thoughts, entitled microdisplay rear projection big screen TV’s development, the subtitle is poised to take off the market with infinite vitality. Now appears that projection did not develop, our country is almost nil. A few years ago several large appliance companies, such as Gome, Suning, Dazhong, sometimes seen as the CRT rear projection, there are micro-display rear projection Zhejiang, such as DLP they do. West Lake in Hangzhou, Zhejiang University, as did the company, as well as LCoS, the last few years we basically did not, even the CRT rear-projection TV was not. So the problem we are seeing a flat, there are two big screen.

Supposedly 40-inch big screen is basically over, say, 55-inch, 50 inch, or even greater. Ordinarily MD from our research and development, it should be said to have many practical applications. For example, excellent value for money, saving resources, saving, environmental protection, wide adaptability, which which is unparalleled. For example, we all need from the family life office, meeting room and so on. Therefore, the micro-display rear projection has been on sale a few years ago, also entered the family, household appliances to see this very good, have increased investment in the projection above, decided to become bigger and stronger. But look at the situation been reversed in recent years, flat-panel LCD TVs LCD and plasma flat panel television striking, ferocious, basically occupying a large screen TV market. Appliance manufacturers would not lose the market, and some turned to flat-panel LCD TV that was several Cooperation There Qingdao, we have told them to engage in micro-display large screen TV, we offer the optical engine, they do end products, micro-display large screen. Some of that move plasma TV, the market revives, the media also active in, in waves, micro-display rear projection with the formation of the industry itself is not strong, a time to back down.

While CRT sales for a long time, we have a deep impression, to the micro-display rear projection TV (MD) large-screen rear projection TV can have some negative effects, CRT has several advantages compared with the other, but there are many deficiencies, such as low brightness, edge sharpness and edge aggregation were lower, power consumption, size large, the quality of a large, heavy, adjust the complex grating by the magnetic effect, convergence is easy variation, defects such as maintenance and difficult. In appearance and microdisplay rear projection similar, people can not tell, in the end is a micro display or a CRT, thus causing the user misunderstanding. Projection also has several problems, the first light bulb issue, a problem is life, sometimes light bulbs are quite expensive, when we do buy a Philips, and spent four thousand dollars of money, we can not say you point How much of the time. Is also made of a light bulb, light source with a save, and now the Olympic Games began large-scale use of the above. These phenomena include the industry chain has just talked about a lot of key parts are not met, are introduced, many of our software was unable to meet according to many software can not do.

So, I said a moment those reasons causing micro-display (MD) rear projection TV in the domestic market share of almost zero phenomenon, including the CRT could not see. For the micro-display rear projection television technology and market development for a rough analysis of this article here, about the idea of a number of years.

I is entitled “Large-screen rear projection micro-display technology advantages and energy saving.” Large screen display and projection display direct two. Directly to large screen display technology generally have a traditional CRT (CRT), such as in vitro display (PDP), non-crystal active-matrix liquid crystal display panels (LCD), field emission display. Large screen projection display technology with CRT projection cathode ray tube: technology is mature, inexpensive, but less light output and clarity, diminishing market share; microdisplay (MD) projection technology: The micro-display device (MD) There are three, namely, high-temperature polysilicon – thin film transistor – liquid crystal device (LCD), digital micro-mirror display devices (DMD), both Sony do. Also, silicon-based liquid crystal display
