If China’s color TV giants each have a label on it, I posted “laser TV†to Hisense, “OLED TV†to Skyworth, and “QD TV†to TCL.
On the basis of LCD TVs, the three major branches of OLED, quantum dots, and lasers are almost simultaneously differentiated. This is something that has never happened in the history of color TV in China.
So, what are the advantages of the three televisions?
With regard to laser television, Hisense describes it this way:
The laser cinema TV adopts the principle of laser reflection optical imaging. The light is soft and it has the immersion and presence of the IMAX screen. The passive optical screen replaces the traditional LCD screen and does not need electricity. The power consumption of the whole camera is reduced to 1/2 of the similar size television. 1/3, mainly for large shopping malls, conference main screen, outdoor display and other places.
What are the sales of laser TVs with such obvious advantages? According to media reports, the total sales volume of all Chinese brands of laser TVs in 2015 was approximately 2,000 units. Some agencies predict that sales of laser TVs in China will increase by 50% in 2016, and the total sales volume is expected to reach 3,000 units.
With regard to OLED TVs, the media description is mostly like this:
OLED is an organic light emitting display technology that can achieve the ultimate black field, unlimited contrast, full-view display, excellent picture performance, and the screen can be freely changed. More and more people tend to think that OLED represents the development direction of color TV.
With regard to OLED TVs and laser TVs, the public’s understanding has been more consistent and there is no explanation for this.
Focus on QD TV.
In a telegram provided by TCL to the media, it is this description of Quantum TV:
"The photoluminescence quantum dot at this stage is a brand-new backlight source. Compared with the traditional white LED TV, the quantum dot product has the ability to override the OLED's full color gamut display, narrow-band continuous spectrum, and higher color purity, 95% Close to natural light, powerful color reproduction, high color accuracy ... so it can be said that quantum dots are currently the best LCD TV backlight technology, can significantly enhance the color performance of the picture, rather than simply increase the saturation so simple." Quantum-dot TVs are based on LCD panels, and quantum dots themselves are high-performance backlighting technologies. Therefore, quantum dot backlights can be used to achieve stunning picture performance on existing products."
This passage points out the fact that the current quantum dot television is actually a quantum dot backlight LCD TV, not the electroluminescent QD TV that most people understand. From the standpoint of backlighting, the so-called "quantum-dot TV" currently on the market, like LED TVs, belongs to the branch of LCD TVs.

Then, in the future is it possible to have a quantum dot TV in the true sense, namely electroluminescent quantum dot television? The material provided by TCL is this:
"The quantum dot technology used at this stage is just photoluminescence, and the ultimate thing to be realized is electroluminescence, that is, self-luminous power. At present, this technology TCL has been successfully developed, mass production is only a matter of time and cost. In the future, even through Quantum dot electroluminescence enables printing production, televisions and curtains can be turned into televisions, and the printing and display technology is promising."
The meaning of this passage is: True Quantum Dot TV, the "print display technology" previously described by TCL, is still under development.
In another paper provided by the TCL to the media, there is such a description:
"If quantum dots really do electroluminescence, it will have the same "self-illumination" characteristics as OLEDs, and the black field will naturally be comparable to OLEDs. However, in terms of color expression, because of the narrow characteristics of quantum dots, its The purity of the three primary colors is far superior to that of OLEDs, so quantum dots will surpass OLED TVs in the era of electroluminescence."
TCL divides QDTV into two eras. Now it is in the first era, that is, QDs can only serve as TV backlighting eras. The next era is the real quantum dot display technology era.
Then, when will the real quantum dot TV come out? The answer given by TCL is: from now on, from R&D to the production stage three years later, the printing technology will be commercialized five years later.
The question is: If quantum dot-TVs will be available three to five years later, then OLED technology will surely become more mature and cost-effective. Even large-scale OLED technology has entered consumers' homes. How can OLEDs compete with OLEDs as a quantum dot-TV? Both are completely out of the starting line.
However, I am still full of expectation of QTL TV described by TCL. Perhaps 3 or 5 years later, the global color TV market will reproduce LCD and plasma 10 years ago. However, when will OLEDs and Quantum TVs dominate the mainstream? It takes time to answer.
As the inventor of Quantum TV, what did Samsung, the global TV leader, say? Recently, in order to differentiate itself from the so-called "quantum dot television" currently on the market, Samsung has given a name to the real quantum dot TV: "QLED." Previously, Samsung technicians said that the quantum dots TV picture performance is comparable to OLED TVs when they introduced the advantages of QD TVs. It can be seen that the goal of quantum dot TVs is to align with OLEDs.

So, which of the three kinds of TV screens, OLED, Quantum-dot TV, and laser TV, has the best performance? My opinion is: If out of 100 points, I judged 98 points for OLED TV performance, 95 points for Quantum TV, and 80 points for laser TV. In other words, the display performance of OLED and quantum dot TV is relatively close, and there is a clear gap between laser TV and the former.
Laser TV has its own advantages. It is currently the largest TV on the screen, watching television has the feeling of movies. However, laser television essentially belongs to projection, which determines that it is vulnerable to ambient light, and there is a clear gap between picture performance and OLED TVs and quantum dot backlight LCD TVs.
Talk about OLED.
I found that when many people talk about OLED, they often stare at the display effect, such as "high definition", "bright color", "dark black field", "infinite contrast", "immediate response", And so on, inadvertently ignored the OLED's biggest value point is the flexible display characteristics. Why is flexible display the biggest value point of OLED? This characteristic determines that OLED can achieve “display everywhere†and make televisions from places that were previously considered impossible to be made into TVs. This geometrically amplified space value of the TV market is so valuable and valuable than its screen performance. many. While LCD TVs cannot afford this social mission, laser televisions are powerless.

At present, the attacks on OLEDs by the anti-OLED camp mainly focus on five points: “high costâ€, “low panel yieldâ€, “resources are in the hands of Korean companiesâ€, “short lifeâ€, and “burn-inâ€. I think that the first two attacks will be completely resolved in the next three years. The last two attacks have been conquered on the technical level. For example, the current normal service life of OLED TVs is about 20,000 hours, which can be seen on a daily basis for 6 hours. In the year, it is 7 years longer than the normal TV service life provided by the state; as resources are monopolized by South Korean giants, with BOE's layout of OLED panel resources, the monopolistic position of Korean companies will be weakened.
In fact, it is not difficult for those with a little logic thinking ability to find that OLED TVs have absolutely no ulterior motives. Otherwise, we cannot explain why a large number of global companies and huge amounts of money are flooding into the OLED field. Why do global mainstream TV companies launch OLED TV products? Why did Hon Hai invest in the OLED field after its acquisition of Sharp? Why did Samsung, which pushes Quantum TV, spare no effort in investing in OLED panels?
The question has come: Why do you know that OLED represents the development direction of color TV, and still companies are resisting it?
It's time to open the answer. Oh I see:
Hisense persisted in laser television because its chief executive, Zhou Houjian, “Koped†this direction 10 years ago. Since it is the will of the boss, of course, the following must be actively catered for. However, it is said that Hisense’s internal strategy for laser television is quite controversial. Many people believe that this is a niche market and cannot support the future of Hisense TV. A peer forecast predicts that once Zhou Houjian retires, laser TV projects are likely to be shelved.
Also, as a strategic ally, Samsung Electronics could not provide Hisense with large-size OLED panels, which objectively hindered Hisense's entry into the OLED TV field.
As for TCL's selection of quantum dots, it is not difficult to understand. The LCD panel industry is the largest source of profits for the TCL Group. Of course, it does not want to see the LCD era come to an end prematurely. After all, OLEDs are just born for LCD TVs. It must be noted that for Huaxing Optoelectronics and TCL, the current biggest threat is not from another LCD panel manufacturer, nor is it another LCD TV manufacturer, but an OLED panel maker, and LG and Skyworth pushing OLED TVs. .
Resolutely slammed OLED into TCL established strategy, TCL believes that this strategy should be undertaken by Quantum TV.
At this point, you may have already understood that what color TV companies choose, and do not choose what direction, is actually the result of a comprehensive game of various factors, not entirely determined by the direction of industry and technology development. Someone who turned to OLED and some people refused to turn around for OLED is understandable.
Finally, the latest news was added: The 6th generation of BOE (BOE) 6th-generation AMOLED production line, with a total investment of 46.5 billion yuan, has been capped on the main plant on July 22 and is expected to be officially put into production in 2017. According to IHS DisplaySearch data from industry information agencies, flexible AMOLED displays will gradually become the mainstream of the display industry. From 2016 to 2022, the compound annual growth rate of flexible AMOLED display requirements is 35.1%.
In addition, according to a color TV business executive, BOE's large-screen OLED panel may be launched before the end of 2016, and the global supply of large-screen OLED panels exclusively from LGD will be broken. At the latest by 2017, OLED panel prices will be significantly reduced again, which will drive down the price of OLED TVs. The arrival of the OLED era may be faster than we expected.
