In the projector market, one that can be said to be a latecomer and has an inestimable development prospect is the laser projector. Since 2016, the laser projector can be said to be in full bloom, whether it is a laser home projector or a laser engineering projector , Laser micro projector or laser education projector, all major manufacturers are actively layout, covering the whole line. But what are the advantages of the laser pointer projector? I believe many consumer friends are still a bit confused. Today we will take a look at the charm of laser projectors.
First look at the Baidu Encyclopedia explanation for laser projectors: laser projectors use laser beams to transmit images. Among them, the optical components of the laser projector are mainly composed of red, green and blue light valves, beam combining X prism, projection lens and driving light valve. There are red, green and blue lasers in the laser projector. The laser beam passes through the expansion of the corresponding optical components and processing chips in the machine, and then transmits to the X prism to integrate the three laser beams, and then the integrated green laser pointer is transmitted by the projection objective to the projection screen to complete the entire laser projector. Display process.
I believe that everyone has not read this explanation so thoroughly, so here I explain the secret of the laser projector layer by layer. At present, laser display technology mainly includes LED + laser, phosphor + blue light, three-color laser technology and two-color (red + blue) technology. LED + laser hybrid light source technology is oriented to the low-end market. The brightness of this light source device No more than 3000 lumens, phosphor + laser light source technology is aimed at the low-end market projection.
The highest brightness of related equipment can exceed 10,000 lumens, and the three-color laser is considered to be the most pure laser light source, mainly for the high-end market, the brightness of related equipment is basically above 20,000 lumens; and the appearance of the two-color laser technology projector is in blue light + On the basis of laser light source technology, a red laser is added, which can bring greater color gamut coverage, better color display, and richer red details to the laser projection, while dual-color laser technology retains the economics of monochromatic fluorescence technology The advantages.
Compared with the traditional lamp projector, one of the biggest advantages of LED + laser hybrid light source technology is that it has a long life. Using a combination of LED + laser and a projector has a lifespan of up to 30,000 hours, which can basically save post-maintenance costs and use costs. The brightness attenuation of the light source projector is not obvious for a long time. However, the disadvantage of the LED + red laser pointer light source projector is that its brightness is limited, and the technical structure of the light source is relatively complicated. For high brightness and technical difficulty The prospect is not very clear, so it is rarely used on the market now.
