Maybe many people will wonder why OLED screens are almost popular in mobile phones, but OLED screens are rarely seen in monitors? The first thing I want to answer is that there are only a few high-end and expensive models of OLED display on the market. As for why this happens, we need to see the layout of the major OLED panel manufacturers in the world.
At the beginning, I didn't want to sell. In many materials I consulted, it shows that the global OLED panel manufacturers are actively deploying small or large-size panels. As for medium-sized panels such as monitors, it seems that no manufacturers have deployed OLED screens in the main force. Now that you know the conclusion, let's talk about the differences in layout among different manufacturers.
Samsung: OLED market share is still the first in the world, but it is greatly impacted by domestic manufacturers
Among the OLED panel manufacturers, we are most familiar with them, and they are also the manufacturers with the highest market share of OLED panel at present. Samsung mainly has three production lines in OLED: A1-A3, l6-l8 for LCD panel, L6 for commercial panel of IT products and L7 / L8 for TV panel.
Although there are both OLED and LCD production lines, Samsung obviously focuses more on small OLED at present. L7 production line is planned to sell some liquid crystal production equipment and rebuild it to produce OLED panel. In the first two years, Samsung decided to invest 325 million US dollars to increase the capacity of A3 flexible OLED production line to meet the growing demand for OLED panels.
In addition, Samsung plans to build a production base for the 6th-generation flexible OLED panel called
LGD: mainly concentrated in large-scale TV OLED panel
LGD is the only large-scale OLED TV panel manufacturer in the world, and LGD's OLED production lines are mainly concentrated in large-scale panels and small-scale panels, among which the 8.5 generation OLED production line built in Guangzhou was officially put into production in August 2019, and 10.5G in South Korea is planned to be transferred in 2021 The OLED production line starts mass production, and plans to deploy in the field of small and medium-sized OLED panels will be strengthened.
It can be seen that the OLED panel of LGD mainly focuses on the large size of TV, and the small size panel is also actively deployed. From the beginning to the end, there is no such medium size as the production display.
BOE: OLED develops rapidly and wins big apple orders
In recent years, BOE's attention has been more focused on small-scale OLEDs. In 2017 and 2019, six generations of flexible AMOLED production lines were put into production in Chengdu and Mianyang respectively, and the first 6.47 inch water drop curved flexible screen was mass produced in Mianyang. And just a few days ago, BOE took Apple's big order: from 2021, BOE will provide 45 million OLED screens for Apple's mobile phones.
The contract will enable BOE to surpass LGD and become the second largest iPhone supplier. Although Samsung still supplies most of Apple's OLED panels, the number will be reduced from 230 million to 150 million.
Other domestic panel manufacturers: actively deploy OLED production lines to strive for market share
According to IHS Markit, in Q3 2018, Samsung accounted for 94.2% of the small size flexible OLED panel market, almost monopolizing.
In recent years, domestic manufacturers are actively laying out OLED production lines. Since 2015, BOE, Shenzhen Tianma and other manufacturers have announced the construction of the 6th generation AMOLED production lines. By the middle of 2017, there were 18 flexible AMOLED production lines under construction and planned to be built globally, 11 of which belong to Chinese enterprises.
According to IHS forecast, by 2020, Samsung's market share of OLED panel will rapidly decline from 95% to 52%; BOE, the second, will have a market share of 15%; South Korea's LGD will be ranked third with 11%; Shenzhen Tianma and Huaxing optoelectronics will be ranked fourth and fifth with 5-6%.
In this table, the T4 project of csot was launched in 2016, mainly with small AMOLED, while the T7 project, mainly with large OLED, including ultra-high resolution 8K display equipment, will apply the OLED manufacturing technology of ink-jet printing. Later, it should continue to invest according to the market demand to increase the capacity of OLED, and TCL displayed Mini at the 19 German electronic exhibition LED display technology of TV shows that csot is also very active in the layout of new technology.
The list does not mention that Vicino is the earliest domestic enterprise involved in the field of OLED, for the technical route of Vicino, according to the former General Manager of Vicino, in the small and medium size, the use of
and glow AMOLED production line project Key products include:4.5
Xinli mainly produces small and medium-sized products under 10.4 inches, which are mainly used in vehicle electronics, medical electronics, military electronics and precision instruments.
So the remaining low-end AMOLED production capacity in China is not only consumed by entry-level mobile phones, Shanzhai mobile phones and non mainstream brand mobile phones, but also entered the market of maintenance and screen replacement.
From high-end OLED TV reasoning to high-end OLED display
Let's take a look at the situation of large-scale OLED TVs. According to oviravo data, in 2018, the global OLED TV shipments reached 2.4 million units, up 69.4% year on year, but the global OLED TV penetration rate was only 1.1%.
Among the many panel manufacturers mentioned above, many are also making large-scale TV OLED panels, with such hard investment and so much publicity among consumers, but the global OLED TV penetration rate is only 1.1%. After all, the positioning of OLED TV is expensive high-end products, which can be understood. As you can imagine, the penetration rate of other less concerned areas, such as PC display, is even lower to almost negligible.
According to oviravo data, in 2018, the global OLED TV shipments reached 2.4 million units, an increase of 69.4% year-on-year. However, according to ihsmarket data, in the second quarter of 2018, the penetration rate of OLED TV in the high-end market with more than $2000 was 59% in Japan, 44% in North America and 45% in Europe.
In a word, although the overall penetration rate of OLED in large-scale products is still very low, the penetration rate in high-end TV market is very high, half of which is OLED TV, and the growth rate is very fast.
Will there be more OLED displays in the future?
I think the answer is certain. According to the forecast of prospective industry research institute, the global OLED output value scale will reach about 50 billion US dollars in 2020, and the global OLED output value scale will grow to a peak of 58 billion US dollars in 2025.
At present, we see a lot of new screen technologies on OLED, such as flexible screen curved screen, 88 inch super size, 8K ultra-high resolution screen, etc., which shows that the overall capacity and high-end technology are improving, so when the capacity of OLED is expanded to a certain extent in the future and more capacity can sink to more display fields, the PC end display will definitely be one of them.
From the current PC display, the most rapid development in recent years is the e-sports screen: high refresh rate, ultra wide screen, larger size, and higher resolution. I think the panel type will definitely go further in the future. At present, compared with TN screen, there are more and more IPS screens with better display effect. Then in the future, OLED display will certainly be more and more, and the price will be more and more people-friendly, which is just a matter of time.
Although OLED screen still has many disadvantages, but generally speaking, the disadvantages are not hidden
The excellent display effect of OLED screen is recognized. OLED screen has high color gamut, high contrast, fast response speed, and the display effect is undoubtedly more excellent. It can also be used as a clock or picture frame, as well as the novel characteristics of folding and bending.
In the use scenario, OLED is used on the display, the screen size is larger than the mobile phone, and the viewing experience will certainly be better; when playing games, faster response speed can bring higher refresh rate and less drag; while in professional design and film and television production, a higher color field can display a richer color space and so on.
This is also used in notebook or display, but it is concentrated in a few high-end products. For example, the mb16ahp of ASUS proart series, which costs 39999 yuan, uses a 4K resolution OLED screen. In addition to excellent color performance, it also supports a variety of HDR formats, as well as a 0.1ms fast response time and ASUS Proart calibration technology can provide fine-tuning of color accuracy and uniformity compensation.
OLED screen is excellent, but there are still some shortcomings to be overcome, such as screen burning, especially if it is used as a display, an icon appears in the same location for a long time, which may aggravate the risk of screen burning. There is also PWM dimming, OLED screen will use low frequency PWM dimming in low brightness, some people's eyes are more sensitive may be more uncomfortable, but now many manufacturers have introduced DC dimming to solve this problem, but the solution effect is also different according to manufacturers. There is also the cost, which has been mentioned before. When the capacity increases in the future, the cost will be even lower.
Conclusion: OLED screen is developing rapidly. We hope that domestic manufacturers will continue to make efforts
Finally, let's talk about the OLED development of domestic manufacturers. As mentioned above, in recent years, domestic manufacturers have increased their efforts to invest in OLED production lines, and BOE has also won a large order of 45 million screens from apple. Before that, the reputation of domestic OLED screens among ordinary consumers was relatively common. This time, BOE was able to say that it won a breath for domestic screens. I hope that domestic manufacturers will continue to work hard and be recognized by more consumers.
