Sales volume is ten times higher than OLED. Three reasons determine that quantum dots will be the future of high-end large-screen TVs

As a major consumer of televisions with an annual sales volume of nearly 50 million sets, in recent years, Chinese consumers have increasingly higher requirements for television picture quality, appearance, and performance, which is also an important driving force for the technological progress of various television manufacturers. From color televisions to LCD televisions, and then to more advanced and cutting-edge television products, the development of television technology has been a feast for the eyes of Chinese people.

At present, in China's large-screen TV market, in addition to OLED TVs presenting a "high-end" image to consumers, the application of quantum dot technology has achieved a revolutionary improvement in the picture quality and color of LCD TVs. With the trend of increasingly high-end color TVs, quantum dot technology is becoming a technological outlet in the field of color TVs and is expected to lead the future of China's high-end TV industry.

What is Quantum Dot TV?

Quantum dots are a new type of high-tech semiconductor material. This material is made of inorganic matter and is very small, with a diameter of only a few nanometers, so small that it can hardly be divided. Therefore, it is called quantum dots. After receiving photoelectric stimulation, this material will emit very pure monochromatic light, and is one of the most perfect light source materials currently available for display technology.

Quantum dot TV is an LCD TV that uses quantum dot technology. TCL is the first company in the world to develop and promote quantum dot display technology. It released quantum dot TV in December 2014. However, so far, there are only a few companies in the world that can produce quantum dot TVs.

Which is better, quantum dots or OLED?

OLED (Organic Light Emitting Diode) TVs are undoubtedly more technologically advanced than the current mainstream LCD TVs. They have several advantages: 1. They can emit light by themselves and do not require a backlight, so the screen can be made thinner. 2. The screen is flexible and can be bent, so curved screens can be made, making it more comfortable for people to watch. 3. The color gamut is wider, which means more and richer colors, making the picture more vivid and the contrast stronger. 4. The response speed is faster, making it more convenient to watch sports games, play games, etc.

Quantum dot TVs, like LCD TVs, require backlights, but their unique technology gives them huge advantages in many aspects.

First, the color is richer and purer

As we all know, the higher the color fidelity of a TV, the better the viewing experience. When OLED generates colors, it is limited by the performance of the filter. The backlight source using quantum dot material is currently the purest backlight source. Quantum dot TVs using quantum dot backlight sources have achieved unprecedented "full color gamut" coverage, and can display extremely rich colors, presenting 1 billion levels of colors. Richer colors can obviously more vividly reflect the beauty of the real world.

In addition, the backlight used by quantum dot TVs is a blue backlight, which is different from the white backlight of most LCD TVs. When blue light shines on quantum dots, it will emit a very strong light, and it is real colored light with very high purity. When watching programs on quantum dot TVs, the colors of the pictures will be fuller and more vivid, and the white will be cleaner, rather than gray.

Second, longer lifespan and no screen burn-in

The TV is unstable when working and the screen flickers from time to time, which is undoubtedly very annoying. OLED TV is an organic light-emitting diode, which has three luminous materials with different lifespans, which makes it unstable when working. Quantum dot TV uses inorganic materials, and its light stability is more than 100 times higher than the most commonly used organic fluorescent material "Rhodamine 6G". The duration of quantum dot fluorescence life is about 10 times higher than that of organic fluorescence, which can be called a long-life TV.

Since OLED TVs are made of mixed organic materials, after the screen has been working for a long time, especially if a single image is played for a long time, the degradation of organic materials will cause the problem of image retention, which is commonly known as "screen burn-in" or "screen burn-in". However, due to the use of inorganic nanomaterials, the color of quantum dot TVs can be stable for up to 60,000 hours. Test results show that quantum dot TVs can achieve "no screen burn-in for ten years", which is a quality that has never been achieved in previous TVs.

Third, cheaper and more cost-effective

For consumers, the price of a TV is an important consideration when purchasing. When spending tens of thousands of yuan to buy a TV, most people still have to weigh it carefully. In the high-end TV market, the price of quantum dot TVs is cheaper than that of OLED TVs. At present, if you buy a quantum dot TV, you can buy a 10-inch larger one with the money you spend on an OLED TV.

As the technology and industry chain mature, the price of quantum dot TVs still has room to fall. Considering the picture quality, lifespan, cost and other aspects, quantum dot TVs are obviously more likely to be accepted by the general public.

Quantum dot TV has a bright future

In the high-end competition stage of display technology, the quantum dot TV market continues to be booming. According to data from the well-known market research organization GfK, the retail volume of quantum dot TVs in the Chinese market reached 950,000 units in 2017, which is about 10 times that of OLED TVs. In 2018, the sales volume of quantum dot TVs is expected to reach 1.2 million units.

Although there are more OLED TV manufacturers in the global market and the product growth rate is relatively high, OLED TVs face two major limitations: production capacity and price. Especially in the Chinese market, the future prospects of quantum dot TVs may be more optimistic.

As the only domestic enterprise with vertical integration advantages in the entire industry chain, TCL has been meeting the ever-evolving consumer demands and quality living standards in terms of both display technology and viewing experience since launching quantum dot TVs in 2014. TCL's blockbuster product, the X5 primary color quantum dot TV, launched this year, is not only supported by high-tech, but also has a curved screen and other exquisite exterior designs, making it a unique and classic product.

I believe that with the upgrading of China's overall consumption structure and the holding of sporting events such as the 2018 Winter Olympics, the World Cup and the Asian Games, TCL's large-screen quantum dot TV will become a new favorite among consumers and better improve the quality of life of the Chinese people. Let us wait and see.
