What is laser tv laser tv? It uses continuous laser with three wavelengths of red, green and blue generated by semiconductor pumped solid-state laser as the light source of color laser tv, and controls the three-color laser to scan images through TV signals. Its color gamut coverage can theoretically be as high as more than 90% of the human eye range. This is higher than the current 62% color gamut coverage of LED TV.
The improvement of color gamut coverage can not only make the whole TV picture look more real, layered and transparent, but also greatly improve the clarity of the picture with the improvement of color saturation. Because the laser is used as the backlight of TV, laser tv can be made thinner and suitable for home use. Laser tv also overcomes the discomfort caused by the fluorescent color produced by human eyes watching the fluorescent powder for a long time, and has no radiation to human eyes.
Characteristics of laser tv Compared with traditional TV, laser tv has the following characteristics:
1. Laser TV has bright colors, high brightness, flexible screen size, and bright images can be projected onto surfaces of various materials, even curved surfaces. This system can also adapt to all TV standards currently used, namely PAL system, NC system, SECAM system VGA or HDTV.
2. laser tv is the strongest competitor in the TV market in 2 1 century, which is simpler and brighter than plasma TV technology. The brightness of laser tv is brighter than that of large-screen LCD TV, and it is not affected by the directivity of viewing angle.
3. The laser is 100% monochromatic light, and laser tv red, green and blue light are modulated separately, so the color effect is very ideal. Its room temperature life can generally reach 654.38+ million hours, and the room temperature life calculated by high temperature aging test can reach one million hours. It is a product with long life and high reliability.
4. laser tv uses a laser beam to project an image, so in the case of high brightness on a large screen, if the projected high-power laser beam directly irradiates the eyes of the viewer, its safety cannot be ignored. So at present, the rear projection laser tv of closed optical path is the main direction.
5. The front projection laser tv screen for desktop is small in size, so the laser power is very small and it is safe to watch. In the case of external power supply and wireless receiving unit, the mainframe can be made into the size of a cigarette case, and corresponding products have appeared abroad.
6. Safety. The red, green and blue visible laser beams in the TV set are projected onto the screen after passing through special beam expanding and shaping equipment. Even if the screen is broken and the laser is accidentally emitted from the screen, it will not have any adverse effects on the human body.
