Laser TV is getting more and more attention, but many people don't know about laser TV.
What is a laser TV?
Laser TV is a laser light source projector and projection screen using reflective ultra-short-focus projection technology, which can also display a good picture in a high brightness environment.
principle:
A laser always emits light of a defined wavelength and color, and a red, green, and blue color can be generated by mounting a special crystal or light guide in front of the laser, and then the laser is converted into a desired color by so-called focusing in these materials. During the screening, the red, green and blue data are sent to the modem inside the laser unit, and the video data is converted into optical information by amplitude modulation, and the three-point rays with red, green and blue lines are combined into a single laser beam, and the laser containing all the image information is included. The bundle is then sent to the projection head through the fiber optic cable and finally projected onto the screen.
Advantage:
1. The laser TV has bright colors, high brightness, flexible screen size, and bright images can be projected onto various material surfaces or even curved surfaces.
2. The laser is 100% monochromatic light, and the laser TV is modulated by red, green and blue light respectively. The color effect is very ideal, long life and high reliability.
What needs to be taken care of?
1. It is difficult to touch the installation
Laser TV is an ultra-short-focus product, which means that a laser TV can be placed on a TV cabinet to project a screen that is close to 100 inches. The size of the laser TV screen, as well as the matching of the edge of the screen and the screen, is determined by the position of the laser TV. Therefore, once the position of the laser TV is moved, the user needs to re-adjust the edge of the screen and the position of the screen.
2. What should I do if the laser highlights the eyes?
There may be no problem watching the picture of the laser TV, but the eye is directly aimed at the lens of the laser TV, then the energy of the laser is much larger.
However, some products have begun to consider this problem, which provides a reliable solution, that is, sensors are installed on both sides of the lens, and only the obstacle appears in front of the laser TV lens, then the laser TV will automatically black. In this way, even if the child's curious probe comes over, there will be no problem that the laser light will hurt the eyes.
3. Focusing is not convenient, manual is very troublesome
Many laser TV products offer manual focusing. This method of focusing is not very convenient. Users need to be close to the laser TV to adjust the focus. The current price of laser TV is not cheap, for a high-end product, it is appropriate to provide automatic focusing. After all, the price of tens of thousands of yuan, also allows users to always run back and forth when operating, it is also very inappropriate.
Although laser TV is a new product, it is developing at a faster rate. Many consumers are paying attention to this product. Many brands have also begun to enter this market. However, the history of laser TV is still not long after it is born. Many manufacturers consider this product based on the perspective of traditional projectors, and the understanding of ordinary consumers is not thorough enough.
