With the improvement of people's health consciousness, consumption concept is changing gradually. For example, in the past, people may put the picture quality and sound quality first, but now more and more people are more concerned about the "eye protection" function of TV. It is believed that many consumers who pay close attention to the TV industry have heard about the publicity of "laser TV eye protection". Is laser TV really good for eye proctection? Does laser TV harm your eyes?
Generally speaking, the light of laser TV is directed through the lens to the screen for imaging, and then reflected from the screen to the eyes of people. Thus, the light after the secondary transmission has lost its harmfulness and will not hurt the eyes. Industry insiders said that such publicity can not be wrong, but not comprehensive.
First of all, the essence of laser TV is projection. Even if the image quality is good enough, it still can't be compared with LCD TV. Both the definition and color performance are projection level. A little light in the room has a great impact on the image quality. For TV products that can't even see the picture clearly, even if the light is softer, no one believes that "eye protection".
Secondly, laser TV uses laser as the light source, and uses ultra short focal projection technology to turn the blue laser through the color wheel to the digital micro mirror for imaging. Therefore, its blue-ray peak is especially high. The "eye protection and blue-ray prevention" often heard is to prevent the light that is harmful to the user's vision. So the reflection of the blue-ray from the laser TV is still blue ray. What's the explanation for "softer reflection light". Limited by many factors such as technology and cost, most laser TVs on the market do not emit RGB tricolor laser, but use a blue semiconductor laser generator, which is often called monochrome laser TV.
The working principle of this laser TV is to rotate the blue laser through the Fluorescent Pink wheel at high speed to form two kinds of light sources: red and green, and then output the picture to the screen of the laser TV through the DMD chip and the analysis lens. Because the light source is mainly high-speed blue laser, the blue-ray peak of this kind of laser TV is very high, which can easily lead to the increase of the toxin in the macular area of the human eye and cause irreversible damage to the vision.
