Laser projection is the top technology of the latest development trend

At present, the highest brightness that can be achieved by a single projector on the market is 33,000 lumens, and the service life of its light source is only 800 hours. The laser projector can output up to 50,000 lumens or more, and the service life of the light source is still more than 20,000 hours. The laser display technology with many advantages will greatly increase the use of projection. It can be asserted that the use of laser display technology will enhance the entire projection Market application space.

Broad development prospects

Laser display technology represents the latest development trend of projection display technology. It has achieved a major breakthrough in colorimetry on the basis of inheriting all the advantages of digital display technology, and has solved the long-term unresolved large color gamut color reproduction in the field of display technology. Puzzles. Because the laser has a line spectrum, the spectral distribution of the laser is very narrow, which can achieve high color saturation and present the most colorful colors; at the same time, the laser spectrum is rich, the color gamut of the laser spectrum is extremely high, the image is the richest in color, and can be perfectly reproduced Natural colors. Therefore, laser display technology is considered to be the mainstream display technology of the next generation.

Laser display imaging optical path

At present, the color reproduction capabilities of display devices such as CRT, LCD, PDP, DLP projectors, and movie projectors that are currently on the market have not broken through the color space of the NTSC system, and the color gamut space can only cover the color space recognized by the human eye. 31.8%, it is difficult to truly restore natural colors, this deficiency has become an important obstacle to further improve the display quality. Compared with the traditional light source in terms of color gamut, LED is a good light source technology, but due to its characteristics of flood lighting, the lack of high brightness and large screen display greatly affects the application space of LED in projection display technology. The difference is that the laser has a very high intensity, which provides the basis for high-brightness, large-screen and super-large screen displays. Laser light source is the best light source to meet various high-end display requirements. Therefore, the industry calls laser display technology "a revolution in the history of human vision."

The foundation of the laser display industry includes technology-intensive high-tech industries including artificial crystal materials and devices, compound report materials and devices, all-solid-state laser technology, optical processing technology, electronics and microelectronics, etc. The future market size will be Reached 57 billion USD / year, especially when the combination of sophisticated laser technology and the huge display terminal industry of hundreds of billions of dollars, such as projection, movie projection equipment, televisions and other display markets and even mobile phones and other micro-projection markets At the same time, these industries will achieve leapfrog development on the original basis.

Laser display industry chain distribution

Taking the projection market as an example only, global projector sales are growing at a rate of about 35% annually, while the Chinese projector market is growing at a rate of more than about 40%, and its market development potential is huge. Relevant people predict that the home projector market will increase at a rate of 200% in the next 7 years. In 2007, 110,000 units entered Chinese households. According to the forecast data of Displaysearch in June 2007, the global display market in 2009 will reach 107.8 billion US dollars. The projection market It will occupy a 30% -40% share, that is, about 6-8 million units per year, and about 10% in China, with a market of 600-800 thousand units / year, and a market space of about 7 billion yuan / year.

Expensive lamp replacement costs and noise issues have always been the biggest obstacles for projectors to enter the home, and the laser light source can precisely solve these two problems. In addition, laser projection can maintain high image quality (tens of thousands of hours) for a long period of time without changing the bulb, while achieving the highest brightness projection display effect.

At present, the highest brightness that can be achieved by a single projector on the market is 33,000 lumens, and the service life of its light source is only 800 hours. The laser projector can output up to 50,000 lumens or more, and the service life of the light source is still more than 20,000 hours. The laser display technology with many advantages will greatly increase the use of projection. It can be asserted that the use of laser display technology will enhance the entire projection Market application space.
