At this year's AWE exhibition, a group of smart home appliances and new electronic products unveiled the attention of consumers, and smart TVs launched by major manufacturers are the key targets pursued. At the moment of serious product homogeneity, in order to be able to differentiate from other brands and come to the fore, many businesses put their own products on a variety of new terms, such as "smart TV", "laser TV", "ULED TV "," "QLED TV", "artificial intelligence TV", "AR \ VR TV" and so on, really dazzling.
When consumers purchase TVs, they must keep their eyes open and not be fooled by the so-called "new concepts" of businesses. Recently, South Korea's KBS News pointed out that the current name of the QLED on the market is unreasonable, because it is not self-luminous technology, but the use of the name of the QLED declared LCD TV.
In other words, the so-called “QLED TVs†that are on the market are businesses that cater to the pursuit of high-tech by the vast majority of consumers and deliberately play word games to attract everyone’s attention. This is in fact a marketing tool.
So what are the TV speculations in the market and what are the real scientific and technological strengths? How to judge as a consumer? Do not worry, to understand these new terms, you must first understand their technology.
The QLEDs on the market are just "improved" LCDs. It takes ten years for commercial QLEDs to be Quantum Dots Light Emitting Diode Display, and the Chinese name is "Quantum Dot LED Display." Its core imaging material is very small in size. Quantum dots, whose quantum dots consist of a combination of zinc, cadmium, selenium, and sulfur atoms. When quantum dots are stimulated by light or electricity, they emit light of different colors according to different sizes.
Another important milestone in the "solid-color hard-screen" liquid crystal display is precisely because QLED self-luminous technology is difficult to achieve, and LCD TVs have huge market capacity, so many QLED manufacturers use a "detour strategy", first in the LCD TV On the development. But this also proves that LCD TV technology is also steadily advancing, especially in the most important aspect of picture quality. At the beginning of this year, a kind of LCD TV adopting "solid-color hard-screen" technology can allow better and more realistic colors and a wider angle of viewing. It is gradually entering the consumer's field of vision and is favored.
"Solid-color hard-screen" technology is similar to but not the same as QLED. The "hard-color hard-screen" TV uses a uniform nanoparticle film (80,000 to 100,000 nanometers for human hair), while the current QLED technology is in LCD technology. A quantum dot film composed of 2 to 10 micrometers of non-uniform particles was added. In contrast, these nanoparticles are smaller than quantum dots. The solid color hard screen enhances the purity of the colors displayed on the screen by absorbing the remaining light waves, resulting in a stunning picture quality effect. For example, green on a regular TV can be mixed with other color wavelengths (such as yellow or blue), resulting in color fading and a yellow or cyan tone. Solid-color hard screens minimize the problems of fading, image instability, and other color discoloration; they also reduce halos on the screen, ensuring that the images are presented in high quality even if the screen is surrounded by strong ambient light.
TVs equipped with solid-color hard-screen technology can allow viewers to see consistent colors when viewed from the front of the TV and from the side, with almost no chromatic aberration. This is an ideal large-size, high-definition television. The breakthrough achieved by solid-color hard-screen technology can be another important milestone in the history of color display technology.
The competition triggered by the new generation of display technology has given the TV market a new vibrancy, but it is only in the interests of users that meeting the needs of users, rather than playing any word games, is the ultimate future.

QLED device structure and light emission principle
In fact, the QLED TV panel is still using a backlight module. A layer of quantum dot film is applied between the backlight and the TFT panel to increase the color performance of the QD TV. If QD film is extracted, QLED TV is no different from ordinary LCD TV. Therefore, the current QLED display technology is still making a fuss on the LCD screen, which is at most a certain improvement and improvement of the LCD, and does not change the nature of the LCD. Some of the persistent problems of the LCD screen still exist. If you have to give it a name, it should be called QD-LCD. Current QLED TVs on the market only cover a layer of quantum dot film on the LCD
At present, the real QLED technology is still not commercialized in the laboratory, and QLED quantum dots are unable to achieve evaporation because they are easily affected by heat and moisture, and can only wait for the inkjet printing process to mature. QLED technology, which is still in its infancy, has not yet solved the technical problems of stubborn existence of poor reliability, low efficiency, unstable blue component life, and difficulty in solution process R&D. Therefore, the industry believes that it takes at least 10 years to commercialize genuine QLEDs. .
