In the projector market, one can be said to be later is the laser projector and the development prospects immeasurable, since 2016, the 3000mw laser pointer projector can be said to be in full bloom, whether it is domestic laser projectors, laser projectors, laser micro projector or laser projector education, major manufacturers are actively layout, full coverage. But what are the advantages of laser projectors?
Laser projectors use laser beams to transmit pictures. The optical components of laser projector is mainly composed of red and green and blue light valve, beam X prism, projection lens and light valve drive. In the laser projector, there are red, green and blue lasers. In the machine after the laser beam expanding optical elements and the corresponding processing chip and then transmitted to the X prism three laser beam integration, and then by the projection lens for the integration of the laser transmission to the projection screen, complete the whole process of laser projector display.
Laser display technology At present, there are mainly LED + laser, phosphor + blue, three-color burning laser pointer technology and color (red + blue) four kinds of technology, LED + laser hybrid light source technology is for the low-end market, the light source equipment brightness Not more than 3000 lumens, phosphor + laser light source technology is aimed at the low-end market projection, the maximum brightness of the relevant equipment can break 10000 lumens, and three-color laser is considered the most pure laser light source, mainly for the high-end market, related The brightness of the device is basically more than 20000 lumens; and the emergence of two-color laser technology projector is based on the Blu-ray + laser light source technology, an increase of the red laser, can bring the laser projection more color gamut, better color display , Richer red details, while the two-color laser technology has retained the advantages of monochrome fluorescence technology economy.
LED + laser hybrid light source technology Compared to the traditional lamp projector, one of the biggest advantages is to have a long life, the combination of LED + laser projector life of up to 30,000 hours, the basic can save the latter part of the maintenance costs and use costs, and this Of the light source projector for a long time to use the brightness attenuation is not obvious, however, LED + blue laser pointer light projector is not good place where the brightness is limited, and the light source technology structure is more complex, for demanding and technical difficulty level, the prospects are not Too bright, so now the market has been rarely used.
Phosphor + Blu-ray hybrid light projector (that is, we usually called the Blu-ray laser projector) is the use of blue light source, through the high-speed rotation of red and green and other colors of the phosphor wheel, the use of rotating phosphor color wheel technology Produced red, green and blue three primary colors, and to achieve at different times produce different colors of light output, and ultimately the output of white light. This technology has overcome the 20000mw laser pointer technology in the efficiency and reliability of the most fundamental technical problems, to achieve a more pure color quality, closer to the international standard color gamut, and high life expectancy, generally more than 20,000 hours, while security Stronger, no breakage risk, environmental protection and even more However, due to the nature of the phosphor + blue light source, can only be achieved with a single DLP, which for the business, engineering, education market, there are also deficiencies.
ALPDTM, the fluorescent laser display technology, uses similar mainstream LED lighting and display the basic technology of blue light plus fluorescent materials, creatively invented the remote rotating fluorescent device, cleverly solved the problem of fluorescence conversion heat quenching in high density laser Under excitation, still maintain high conversion efficiency. While the use of GaN blue laser and YAG and nitride fluorescent materials, the effective continuation of the LED high reliability and long life and so on. ALPDTM laser light source also has the advantages of traditional LED, but also to solve the shortcomings of both, as a new class of light source, has become a major breakthrough in the history of laser light source.
The three-color pure laser technology is the industry’s most pure 5000mw laser pointer light source, which has a rich color, color saturation and other advantages, can be the most natural nature, the most beautiful, the most real color, a major field of laser display technology development At present, the use of three-color pure laser light source projection equipment has penetrated into the simulation, exhibition, conference center, outdoor curtain wall and digital cinema, home theater and other fields, has great room for development and broad application prospects.
