Quantum dots / OLED / laser These three TVs are more promising?

Regarding the future development of display technology, the debate has never stopped. Some people are not optimistic about LCD technology. They think that OLED display technology will definitely eliminate LCD technology. Some people think that the cost of OLED display technology is too high, but the advantages are not so great. Obviously, the future prospects are not necessarily good. With the advent of laser light sources, laser television products based on reflective ultra-short-focus technology seem to bring new choices to home users. In the end, which of the three technologies is more promising? Today we will analyze it.

Let us first look at quantum dot technology. This kind of technology belongs to the improvement technology of the liquid crystal technology, is to add a quantum dot film behind the traditional liquid crystal panel, this quantum dot can emit the pure color light of RGB three colors under the excitation of the blue LED light source. We all know that the RGB three-color backlight is better than the current blue LED hybrid yellow phosphor's white color gamut, so that quantum dot technology can effectively improve the LCD panel display color.

Only a certain short board of the LCD panel has been improved. From the perspective of technological development, it seems that the quantum dot technology is only a transitional technology. Because OLED panels inherently have a wide color gamut, even reflective ultra-short-focus projectors with laser light sources have natural color advantages. However, judging from past experience, a technology has a better color, and it cannot be guaranteed that this technology will surely win the final victory.

Plasma display technology may not be familiar with many after 00, because now is the world of LCD panels. In fact, at the beginning of this century, the tussle of plasma and liquid crystal technology was very hot. At that time, the store plasma TV was positioned as a high-end, because it was a specific one with a wide viewing angle and high-quality color, and the performance of the LCD panel was almost equivalent to that of the two panels. However, the final outcome was the elimination of plasma technology, which eventually became the most widely used display technology for display applications.

This development trajectory makes LCD the most expensive display technology at present. China's LCD panel industry is booming, and LCD production bases are constantly appearing throughout the country. Therefore, the supply of LCD panels in the Chinese market will be very large in the future. The combination of quantum dot technology and liquid crystal panel technology is simple and effective. It does not require large-scale transformation of existing production lines, and it can also improve color performance.

This is a double-edged sword. In the future, QDs will have favorable price display, and their color performance will not be worse than that of OLED panels. Even though the thickness of the LCD panel is a bit larger, in the home market, the thickness does not seem so important. Judging from the current technological development, it is unlikely that OLED TVs will completely replace LCD TVs, and it is not necessary at the same time. I believe that the main future of quantum dot LCD panels is the indoor large-screen market, which is the continuation of traditional LCD TVs.

OLED TV competitive advantage is not obvious

After two to three years of development, consumers of OLED TVs can now purchase them, but the prices are still high and they cannot compete with ordinary LCD TVs. At the same time, OLED TVs can achieve curved surface effects. After the process of hype, sales, and consumer feedback, manufacturers and consumers have found that a simple curved surface does not bring much superior display effect.

Indeed, OLED TVs have the advantages of high color quality, wide viewing angles, and ultra-thin, but these advantages are not particularly prominent for products placed in the living room, and they lack real appeal for ordinary consumers, especially when we mention After the emergence of quantum dot technology, the original color performance of LCD panel TVs has also dramatically increased. As a result, the advantages of large-screen OLED TVs have left the advantages of a wide viewing angle and ultra-thin.

In fact, the advantages of wide viewing angles of OLED panels are not obvious. After years of development of LCD panels, there has been a wide viewing angle technology such as VA and IPS, which can basically reach a viewing angle of 170 degrees. This viewing angle is still better than OLEDs. The panel is poor, but when actually watching TV, how many people will use the ultimate viewing angle? Basically, everyone is sitting on a sofa and watching television programs. The visual angle has little effect on consumers.

Just because of such an advantage as ultra-thin, can OLED TVs defeat LCD TVs? I hold a pessimistic attitude toward this point. The author believes that the real advantage of OLED panels is energy savings. Because the OLED panel displays part of the image, it does not light up the entire screen. The LCD panel cannot match this. The backlight of the LCD panel is integrated, and even if only one pixel of the screen is displayed, the backlight must be fully turned on. The OLED panel does not have a backlight, so in the future it can be done to show where it shines.

This advantage can be well applied to mobile devices. Currently, mobile devices are generally low in life, and the screen is a large consumer of electricity. Therefore, the use of OLED screens can achieve a good effect of energy conservation. And the thin and light OLED screen is also very suitable for mobile devices. I think the future of OLED screens is on mobile devices.

Laser TV is a high-end market in the future

What is laser television? In fact, the hardware composition of the laser television has two major parts. The first is the body itself and it is also a reflection-type ultra-short-focus projector. This product is called a laser television because it uses a laser light source. Therefore, the nature of the laser television is A laser source projector that uses reflective ultra-short-focus projection technology; the other part of the hardware is a projection screen, because laser television must be matched with a specific screen, not just a white wall or soft screen can be.

Since it is a projector, the biggest advantage of laser television is the size. Laser TV can easily achieve 100 inches, LCD TVs are 100 inches already approaching the limit, and there is no room for further growth. Even 100-inch LCD TVs are priced at several tens of thousands of yuan, while laser TVs currently have 20,000 yuan, so not only laser TVs have more space for large-size TVs, but their economic effects are also better. of.

Moreover, the size of the laser TV is flexible, users can feel their own needs, and the size of the screen can be flexibly adjusted. The LCD TV cannot achieve this function. Therefore, for various living room environments, the fit of laser television is actually better, and the most perfect size and distance can be adjusted according to the needs of users. 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.

These advantages give laser TVs their unique advantages over quantum dot TVs and OLED TVs. Large size, high quality picture display, which is the basic characteristics of laser television, while the price of laser TV and OLED TV is at a similar level, the future of OLED TV and laser TV may compete for high-end home TV market, laser TV's large size advantage It is obviously better than OLED TV technology. So I think the future of OLED TV lies in the high-end market.

At present, Quantum-dot TVs, OLED TVs, and laser TVs are three kinds of more avant-garde TV forms. Quantum dots are still an upgrade of LCD TVs, while OLED TVs are new products. In fact, laser TVs are essentially projectors. It makes a lot of sense to talk about the advantages of technology, because there will not be a single big situation in the future.
