8K can no longer wait for 4K to become popular before it starts. This is the characteristic of the era of leap-forward development. New technologies will not wait until the old technology is popularized. The possibility of direct adoption of 8K beyond 4K is very high.
In what direction will the future display technology develop? Although the answers given by different companies are different, there are two least controversies: OLED and 8K represent the mainstream development direction of display technology. The biggest possibility is that 8K and OLED embrace each other.
On May 25th, TCL Group announced that it will invest in the construction of a 11th-generation 8K ultra-high-definition new display device production line with annual production capacity of 3,370mm&Times; 2940mm glass substrates, and a 65-inch and 70-inch production capacity in Guangming District, Shenzhen. , 75-inch 8K ultra-high-definition display, and 65-inch, 75-inch OLED display, the total investment of about 42.683 billion yuan, plans to build in March 2021 mass production.
Some of the media reported on this news, but I found that most of the reports stayed at the level of general news reporting and there was little deep interpretation. The fact is that this project will have a great impact on the development of the TCL Group in the next ten years or on the construction of China's display industry competitiveness.
In November 2016, TCL has invested 53.8 billion yuan to build an 11-generation TFT-LCD panel production line, and plans to build it into mass production in early 2019. Why have you built a high-generation LCD panel production line and spent a lot of money building a high-generation production line? Is it just a superposition of production capacity?
If you look a bit, you will notice that this new 11-generation display device production line is very different from the first 11-generation production line. For example, two important issues that did not appear in the first 11-generation line report. Key words - "8K Ultra HD" and "Large-Screen OLED" appeared here.
what does this mean? This means that TCL has implemented the layout in both 8K display and OLED TV. As a result, the significance is significant.
In what direction will the future display technology develop? Although the answers given by different companies are different, there are two least controversies: OLED and 8K represent the mainstream development direction of display technology. The biggest possibility is that 8K and OLED embrace each other.
In other words, most color TV companies will consider OLED and 8K in two directions when considering the future layout. This is indeed the case. At present, most of the mainstream TV companies in the world choose to enter the OLED TV field; in 2017, very colorful companies announced the launch of 8K TVs.
We can basically assert that the mainstream development direction of TV in the future must be over 8 inches of large-screen 8K OLEDs.
TCL's second 11-generation Ultra HD monitor production line project puts one foot on 8K and the other foot on a large-screen OLED. This is the greatest value of the project.
At present, the more far-sighted color TV companies in the world are arranging future display projects, mainly in large-size OLEDs, or mainly in 8K display, and at the same time in the 8K and large-screen OLED two fields are rarely seen simultaneously. Even Samsung, LG, two color TV giants did not do it. Although Sharp's efforts in 8K are large, it is not enough for large-size OLEDs. In contrast, TCL is one of the most heavily invested companies in two major areas at the same time - although it is even faster than Sharp at 8K, it is even stronger than LG in large-screen OLEDs, but overall it is still the best investment. Window period".
Conjecture: TCL may become the world's first printing and manufacturing company
In fact, the most notable aspect of the TCL project is not 8K. It is planned for large-scale printing of OLED production capacity.
At present, we have not yet publicly reported from the media that there is a second enterprise in the world planning to construct a large screen printing OLED project. TCL is the first in the world.
You may say that LG is not it? Seeing clearly, I'm talking about big screen printing OLED project.
A conjecture was naturally proposed: TCL will become the world's first printing and manufacturing TV business?
At present, all OLED TVs in the world are vaporized and not printed. Once TCL becomes the world's first large-scale printing and manufacturing enterprise for OLED TVs (Note: Quantum-dot TVs can theoretically achieve printing and manufacturing), the global color TV industry will be rewritten and China will surpass South Korea to become a global color TV industry. The real leader.
Of course, this is only a hypothesis, and the final answer still needs another three years to be announced, because Samsung and LG are also stepping up research and development of printed OLED technology.
So what is a printed OLED? How is it different from the current sales of OLED TVs? Here is a small science for everyone:
The principle of OLED development is as follows: a layer of tens of nanometer thick luminescent material is formed on ITO glass, a layer of metal electrode is disposed on the luminescent layer, and the electrode is applied with a voltage luminescent layer to generate light radiation, and electrons and holes are injected from both yin and yang stages. The injected electrons and holes are transported in the organic layer and recombined in the light-emitting layer, and single-state excitons are excited by the excited light-emitting layer molecules, and single-state exciton radiation attenuates light emission to form one pixel.
Therefore, luminescent materials play a crucial role in the OLED pixelation process. At present, the manufacturing method of light-emitting materials can be divided into vapor deposition and printing.
Evaporation is the use of current heating, electron beam bombardment heating or laser heating and other methods, so that the vaporized material evaporated into atoms or molecules, the collision of the substrate surface condensation film.
Printing is the use of printing methods to produce organic layers of display materials. By using multiple printing heads on inkjet printing equipment, different colors of polymer luminescent material solutions are accurately deposited in the isolation column grooves of ITO glass substrates. After the solvent evaporates, A thin layer with a thickness of about 100 nanometers is formed to form a luminescent pixel.
Compared with the evaporation process, the printing process has four distinct advantages: 1. The process is simpler; 2. The organic light-emitting material has a higher evaporation efficiency; 3. It is easier to handle large substrates. 4. The manufacturing cost is lower.
A typical statement is: In the use of raw materials for OLED panel, printing OLED can save cost 90% than evaporation technology.
At present, the development of OLED TVs is lower than previously expected by the industry. The biggest obstacle is not the low degree of market acceptance. It is the continuous supply of large-size OLED panels, which directly limits the large-scale production of OLED TVs. The reasons for the shortage of large-size OLED panels can be traced back to Evaporation process is complex, yield is low, and manufacturing costs are high.
Therefore, once the production bottleneck of printing production breakthroughs, large-size OLED TVs will show a "blowout" trend, the market growth is not the current 100%, but 300%, 500%, or even higher; and OLED TV prices may suddenly It is only half the current level, even lower.
In terms of the industrialization of printing and manufacturing, TCL has now taken the lead in the world. In the second quarter of 2017, JOLED (an OLED panel supplier jointly established by Japan Display, Sony, and Panasonic) developed a 2K-inch printed 4K OLED panel; this year, TCL's related company, Guangdong Juhua, has successfully developed 31 inch inkjet printing 4K OLED panel. TCL's goal is to complete the development of inkjet volume production technology by the end of 2019.
However, at present, TCL has not yet launched OLED TVs. It is obviously waiting for the printing technology to achieve a large-scale breakthrough before entering large-scale.
The arrival of the 8K era may be faster than you think
The layout of 8K is another major highlight of TCL's investment.
According to public media reports, TCL's 8K ultra-high-definition panel production line should be the second domestic related investment. In March 2017, Foxconn Alliance Xia popularized the Guangzhou Municipal Government and invested RMB 61 billion in the Zengcheng High-tech Zone to build the 10.5-generation 8K panel, substrate glass and related post-production lines. It is expected to be completed in volume by 2019.
Why TCL increased 8K investment at this time? TCL said that it is expected that 8K products will enter a period of rapid development after 2018. “Reinvesting and building 11-generation panel production lines is an optimistic view of the industry development prospects for large-size and ultra-high-definition panels.â€
The pursuit of higher definition is the aim of all display devices, including color TVs, that will remain unchanged. We know that 8K resolution is 4.3 times that of 4K, and 4K resolution is already comparable to human eyes. All those who have experienced 4K video will have amazing feelings. People who have experienced 8K ultra-high definition video will basically shout "unbelievable."
Not long ago, Sharp and the Beijing Forbidden City displayed the 8K version of “The Qingming Shanghe Diagram 3.0†at the Arrow Pavilion in the Forbidden City. The life of the Jingjing people in the Northern Song Dynasty was displayed in front of the people with the clarity of the present. The visitors even called “Enchanting!†â€
TCL's investment in the 8K ultra-high-definition project is clearly aimed at the future development trend of display technology, in preparation for the rapid demand for 8K products in the coming years.
However, the investment layout of TCL and Foxconn in the 8K field is still quite different. Foxconn is not limited to investment panels and display terminals. Instead, it extends to content production. The structure is an 8K ecology, covering content, transmission, Edit and display the industry-wide industrial chain, including all areas that 8K can touch.
Therefore, Sharp actually assumes the responsibility for 8K industry popularization, enlightenment, and market development; TCL has just entered the 8K panel area and is still unable to talk about the 8K ecosystem.
In the autumn of 2017, Sharp has taken the lead in introducing the world’s first consumer-grade 8K TV.
At present, the mainstream TV companies in the world have basically announced their entry into the 8K field, but most of them still remain at the slogan level and very few consumer-grade products are launched. However, I still optimistically expect that no less than three companies will launch consumer-grade 8K TVs this year. After all, no one is willing to lose to the trend.
8K suddenly increased, there is a very important prerequisite - the rapid commercialization of 5G network is expected to be large-scale substantive landing in 2019. The opening of the 5G network is equivalent to opening up an unimpeded highway for the popularity of the 8K ultra-clear technology.
Japan has already announced that it will implement 8K video broadcasting in the Tokyo Olympic Games in 2020, and it is conceivable that the global 8K display industry will be stimulated.
Obviously, 8K can no longer wait until the popularity of 4K has started. This is the characteristic of the era of leap-forward development. New technologies will not wait until the old technology is popularized. The possibility of direct adoption of 8K beyond 4K is very high.
