The living room display technology is opposite to the sword. Which one do you use?

TV market competition can be considered fierce, the original market has been divided by Japanese and South Korean giants and large domestic producers, there are also many spoilers of the Internet upstart, prompting the color TV technology to continuously upgrade iterative. With the constant innovation and development of science and technology, the speed of its replacement is getting faster and faster. A new technology has been produced to the mass production and the time to market has been continuously shortened, from black and white to bulky CRT TVs to LCD/ PDP, then OLEDs, Quantum Dots, Lasers, etc., but the direction of TV development has always remained the same, moving toward bigger, thinner, colors closer to what people see.
On the one hand, Samsung and TCL mainly push quantum dot technology, attempting to shake OLED's display status. On the other hand, LG, Skyworth, and Konka still stand behind OLEDs, arguing that it is always the mainstream of color TV development in the future. In addition, Hisense, Changhong's laser television also joined the large-screen melee, of course, the father of LCD TV 8K Sharp, television manufacturers began the camp of the struggle.

8K: Close to the human eye limit Brand: Sharp

Although the 4K display technology has a blowout-type explosion, the technology has also been highly mature, but due to the lack of 4K sources, 4K has not been fully popularized, but it does not hinder the development of the 8K display. 8K refers to a pixel with a resolution of 7680×4320 and four times the number of pixels in 4K. Some people think that 8K is the limit of the human eye, and the details of the picture are unmatched. It can completely simulate the human vision and achieve a real sense of immersion and WYSIWYG. With the ever-increasing size of television, the improvement of resolution is the direction that all manufacturers must strive for.

Currently, each panel manufacturer has more than 40 models of 8K panel products in production or R&D, covering a range of sizes from 65 inches to 110 inches, showing that everyone is optimistic about the prospects of 8K panel products. However, 8K products really started to develop in the market, at least until 2 to 3 years later, until the technology matures further and the selling price of the products is closer to the people.

OLED TV: focus on dynamic contrast on behalf of the brand: Skyworth, LG

OLED is also called Organic Light Emitting Diode. It is a self-illuminating screen material. It can control every pixel and it can make up for the flaw of LCD screen light leakage. Therefore, it has perfect black and accurate color performance, wide viewing angle, and painting. Quality lifelike. Bring more extreme black and ultra-high contrast. At the same time, because there is no backlight source, there is an absolute advantage in terms of flexibility and thinness in design.


However, shortcomings such as short life span, residual image, and low yield are difficult to ignore. Due to the self-luminous nature of OLED materials, when the same image is played on the screen for a long time, some relatively short-lived afterimages may appear, and the so-called “burning” occurs with permanent afterimages due to the RGB sub-pixels of the OLED panel. The damage of B (blue) pixels due to a shorter life span results in the impression of a residual image on the screen. The lower yield rate has also led to the ever-higher price of OLED screens. The current manufacturing process of large-size OLED panels is complicated. The luminescent materials are vaporized by vapor deposition technology, which is an important factor in the high cost of OLED panels.


At present, large-size OLED panels can only be mass-produced by LG Display in the world. Only one million OLED TV panels can't meet the needs of a large number of TV manufacturers every year, and it also leads to high OLED TV prices. However, accompanied by many manufacturers of OLED panel **, panel OLED yield has increased from less than 50% to 80%, I believe that has been hindering the stability of OLED panel production and other issues may also be resolved.

Quantum Dots: More Outstanding Colors Represent Brands: Samsung, TCL

Quantum dots first entered the color TV industry in 2014, followed by TCL, Changhong, Samsung and other domestic and foreign manufacturers have launched quantum dot television, because of outstanding picture quality, has gradually become the focus of industry attention. Quantum dots are **semiconductor nanocrystals. Each small particle is a single crystal and only about one ten-thousandth of the size of the hair. Only need to change the size of the quantum dot, you can call up the desired color, and the color purity is very high, brings the full color gamut display capability, narrowband continuous spectrum, higher color purity, 95% close to natural light, powerful color reproduction The color accuracy of the high crystal stability is also very high, which is difficult for other materials.


At present, the quantum dot technology is to add a layer of quantum dot film behind the traditional liquid crystal panel, which effectively improves the display color of the liquid crystal panel. Therefore, the current quantum dot technology is precisely the improvement technology of the liquid crystal technology and has not yet achieved Glowing.


However, in theory, quantum dots have the characteristics of electroluminescence, that is, without the need for backlight source, they can achieve infinite contrast of OLED and exceed OLED in the color gamut. Also, Samsung, TCL and other manufacturers are making every effort to develop quantum electricity. Technical reasons.

Laser TV: Breaking the size 桎梏 Brand: Hisense, Changhong

The laser TV is regarded as Hisson's own son. When many TV giants did not hesitate to pay for the development of large-screen LCD TVs, Hisense opted for a unique way to develop short-focus projection technology and took the lead in the completion of the release of 100-inch 4K ultra-short-focus laser TVs at prices only for LCD panel TVs. One-tenth of it is also a lot of manufacturers heart.





The optical television is not an ordinary projection technology, but in reality, laser television is more like a cross-version upgrade of projection technology. Laser TV consists of two parts. One is the machine itself, a reflective ultra-short-focus projector that uses a laser light source, and the other part is a projection screen. Compared with LCD TVs, laser TVs can easily achieve screen sizes of 100 inches or even larger. The price is much lower than LCD TVs of the same size. Unlike ordinary projections, the contrast and saturation of laser TV screens are greatly increased, they have a good suppression effect on ambient light, and ultra-short-focus performance also saves space.





Therefore, in realizing the large size, not only does laser television have more space, its economic effect is also better. Laser TV just made up for the shortcomings of LCD TVs in large sizes, giving consumers more choices. In addition, the laser television uses a laser light source, which has high purity and high brightness, which means that the color gamut of the laser television is better. However, laser television is still essentially a projection, which determines that it is vulnerable to ambient light, and there is still a gap between the actual picture performance and the theory.

The current trend of display technology is very unpredictable, and the advantages of technology can be described as merits. In general, quantum dot display technology and OLED display technology are very room for development. Laser TV is still in its infancy, but there are many opportunities in the large-screen TV market.

Summary: For consumers, when choosing a color TV, it is not possible to negate any display technology, but to choose according to their own needs and the characteristics of the product. If you are sensitive to color, then the natural choice is naturally Quantum-dot TV. Its black-field effects and color saturation are dominant; martial arts, sci-fi movie enthusiasts, OLED TV is the best choice, high contrast and excellent dynamic picture performance. Good solution to the LCD TV's grainy and smearing problems under high-speed screens. Of course, the budget has also been raised a lot. For consumers who are large enough in the living room to create their own home theater, laser TV is the best choice; Degree, 8K TV is naturally overlord.
Different needs, different tendencies, but the only purpose of the purchase of color TV is to be a big screen, within the allowable range of viewing distance, the bigger the better.
