Those of you who often pay attention to technology products should know that there are three kinds of popular TVS on the market, namely OLED TV, laser TV and QLED TV. OLED TV, as we all know, is closely related to the optical principle, and the display of TV screen cannot be separated from the support of light.
OLED TV
The OLED TV is made of organic compounds. This organic compound says that when an OLED is powered on, the organic compounds give off light independently. That's how OLED TV displays.
OLED TV is more flexible, because of the self-illumination display principle characteristics, greatly enhance the flexibility of the picture display, as long as all the pixels "out", the picture can achieve the effect of all black. However, it is easy to appear the screen burn-in problem, because the organic material of OLED TV is limited, and the display principle of self-illumination, so the phenomenon of heating is an inevitable, once a long time operation, the display screen will be hot, very easy to occur screen burn-in phenomenon.
Brightness is not enough, in addition, due to its own technical limitations, the insufficiency of the brightness of the OLED TV, in order to make up the light, the OLED panel are available in the market on the basis of three primary colors add white markers, nit nit - 1000, 500), was also being criticized by foreign media for 4 k and bring greater than 1000 compared to nit QLED TV, there is a hardcore gap on brightness.
Laser TV
Laser TV sets can cause damage to the eyes. Although the stimulation is not as big as the laser pointer, but businesses are still worried about the laser to the eye damage is huge, so the built-in eye protection mode of the reminder, but this kind of "treatment of the symptoms, not the root cause" eye protection, actually produced very little effect.
Light leaking issues. A lot of people think laser TV price is expensive natural and decent, but buy TV to want to pay attention to the space is put, most Chinese door model and tall, reach the requirement of laser TV, bring about laser to project meeting eventually leak light to the ceiling, so evening use laser TV to watch TV to do not turn off light, can a bit horrible.
QLED TV
QLED TV, QLED TV, also known as quantum dot TV, evolved from traditional LED TV. The white LED backlight is optimized to blue LED backlight, and the quantum dot enhancement film is implanted to make the imaging further.
According to the principle of display, the quantum dot enhancement film is equivalent to the filter of QLED TV screen. The blue LED backlight, through the quantum dot enhancement film, will refine the light to the ideal color temperature and produce pure red, green and blue primary colors.
The color is pure. In addition to making the color extremely pure, under the high brightness picture, the color can still be kept bright and saturated, and will not appear gray and white.
Wide color gamut, has generally 100% color gamut space features, regardless of the picture of the light from the darkness, under the graphics technology of optimization, can present the accurate color film. High contrast, brightness contrast ratio is the highest and lowest luminance contrast, QLED television in more than 1000 nit brightness peak, in the light of circumstances, can be rendered to the stronger contrast effects, even in the case of HDR images emphasize a light, to create a more natural clear HDR effect.
