The bigger and bigger the color TV, the more demanding users are for health and eye protection. At present, laser televisions can project images of 100 inches or more, and their characteristics in human eye comfort are also attracting attention. However, how to determine whether a TV product is eye-protecting? As a display device, the way in which the television refracts the light is not as direct as the sun's rays. It is reflected or refracted by the panel more or less, and the red, yellow, and blue light lines are directly exposed to the human eye. Irritations can be biased, and the imaging principle of the TV may be the key to unlock this fog.
Different from the ordinary LCD TV imaging, laser television simulation of nature's principle of reflection imaging is what people see is the screen reflects light, real natural, no radiation, to avoid the traditional glass screen mirror glare and strobe and other issues. Take the example of Hisense, the current leader in laser television. The imaging principle of laser television is to emit laser light from a laser light source, project three colors of light through a color wheel, and image it on a DMD chip, and then project the light through an optical lens and an ultra-short focal lens to reflect light. The mirror is finally irradiated by a mirror on the screen, and then reflected by the screen to form a complete image. Finally, it enters the eyeball of the person and the reflected light is always seen by the human eye. This imaging method is closer to the natural light spectrum and energy distribution, and is more suitable for comfortable viewing by the human eye.
In addition, Hisense laser TV adopts Fresnel passive biomimetic screen, which has the characteristics of anti-ambient light and high gain. It does not have power on itself, can guarantee zero-radiation interference, and has further protection for human eyes.
Recently, the China National Institute of Standardization has also conducted a special evaluation of visual comfort for Hisense laser televisions. Through patent evaluation techniques and computational models, it analyzes changes in the visual function parameters of human eyes under different fatigue conditions, and finally calculates the viewing of Hisense lasers. Television visual comfort results. The test data shows that Hisense laser television has excellent visual presentation, accurate color vision, high definition, and low visual stimuli. It is a display product with good visual comfort. The visual comfort of Hisense's laser TVs is not only better than that of LCD TVs, but it is also superior to paper readings by more than 20%, and the eye protection effect is remarkable.
It can be seen that laser TVs adopting the fourth-generation display technology have prominent advantages in visual comfort, and this feature may help them become the dominant player in the large-screen television market.

Aluminum Threaded Flange is a kind of flange which uses thread to connect with pipeline. When designing, aluminum forged threaded flange can be treated as loose flange. The advantage of aluminum 1060 threaded flange is that there is no need for welding, and the additional moment produced by flange deformation on cylinder or pipeline is very small. So it's a good choice to choose aluminum 5083 threaded flange.
