OLED (Organic Light Emitting Diode), also known as organic electromechanical laser display or organic light-emitting semiconductor (OLED). OLED belongs to a type of current type organic light emitting device, which emits light through the injection and recombination of charge carriers. The emission intensity is proportional to the injected current. Under the action of an electric field, the holes generated by the anode and the electrons generated by the cathode in OLED will move, injecting them into the hole transport layer and electron transport layer respectively, and migrating to the luminescent layer. When the two meet in the luminescent layer, energy excitons are generated, which excite the luminescent molecules and ultimately produce visible light.
Organic Light Emitting Diode (OLED), also known as organic electromechanical laser display or organic light-emitting semiconductor (OLED), refers to the phenomenon of organic semiconductor materials and light-emitting materials emitting light through carrier injection and recombination driven by an electric field. [2] Generally speaking, OLEDs can be divided into two types based on luminescent materials: small molecule OLEDs and polymer OLEDs (also known as PLEDs). [2] OLED is a device that utilizes a multi-layer organic thin film structure to generate electroluminescence. It is easy to manufacture and only requires low driving voltage. These main characteristics make OLED very prominent in meeting the needs of flat panel display applications. OLED displays are lighter, lighter, have higher brightness, lower power consumption, faster response, higher clarity, better flexibility, and higher luminous efficiency than LCDs, meeting consumers’ new demands for display technology. More and more display manufacturers around the world are investing in research and development, greatly promoting the industrialization process of OLED.
As we all know, on OLED screens, Korean manufacturers have always had the the final say. In fact, Samsung and LG are the two the final say.
Because Samsung and LG started earlier, while Chinese screen manufacturers were still vigorously developing LCD screens, Samsung and LG had already developed OLEDs and vigorously promoted OLEDs.
More importantly, many key equipment in OLED production lines are controlled by Samsung and LG, making it difficult for domestic manufacturers to purchase them, which seriously affects the development of domestic OLEDs.
In the early days, Samsung monopolized small screen OLED screens, such as smartphones, while LG monopolized large screen OLED screens, such as TV OLED screens.
Not to mention anything else, just from the usage of Apple’s iPhone screen, it can be seen that in the early days, Apple only used OLED screens from Samsung and LG.
Until the past two years, JD’s OLED performance has improved. Apple has included JD as an OLED supplier for the iPhone, but the procurement volume is still relatively small, ranking behind Samsung and LG.
However, thanks to the support of domestic mobile phone manufacturers, especially Huawei and others, the OLED screens of BOE and TCL Huaxing are widely used in domestic Android phones.
For example, Huawei has always used BOE’s OLED screens in its Mate/P series, as well as Xiaomi, Honor, OPPO, VIVO, etc. Although its early flagship used Samsung’s OLED screens, it did not forget to support domestic OLED screens.
So domestic OLED screens are constantly rising, and according to Omdia’s latest “Duration Tracking Report for Small and Medium Sized Displays”.
In 2022, BOE ranked second globally in the small and medium-sized AMOLED market, surpassing LG and occupying 12% of the market.
As shown in the above figure, Samsung still ranks first, with one company accounting for 56% of the market share, while BOE ranks second with 12% of the market share, and LG ranks third with 11% of the market share. Afterwards, the fourth place is Chinese manufacturer Vicino, with a share of 6%; And the fifth place is still Chinese manufacturer Hehui Optoelectronics, with a share of 5%.
Panel traversal cycle: Small and medium-sized OLED inventory battle, and Shentianma will launch foldable screens next year. In the manufacturing business card of Wuhan Optics Valley, the display panel industry is one of the important benchmarks. Domestic panel leaders such as Shenzhen Tianma and TCL Huaxing have gathered here, driving the entry of a number of upstream and downstream industrial chains, forming a highland for small and medium-sized panel production capacity.
From the global shipment data of mobile phone panels alone, domestic manufacturers have entered the first tier. According to data from Qunzhi Consulting, the global shipment volume of smartphone panels in the first quarter of 2022 was approximately 436 million units, with BOE, Samsung Display (SDC), and Tianma ranking among the top three shipments.
The development of Optics Valley panel clusters is a microcosm of the rise of the domestic panel industry. The intelligent manufacturing industrial park that has been cultivated for many years has witnessed the rise of the domestic LCD (liquid crystal) industry, and is now witnessing manufacturers unleashing OLED production capacity and competing for OLED technology.
Located in the Tianma Wuhan G6 Industrial Base in Optics Valley, the flexible OLED production line is operating 24 hours a day. After undergoing complex processes such as array, evaporation, and module assembly, the prototype of mobile OLED screens emerged here. The 21st Century Economic Report reporter learned on site that the overall automation coverage rate of the production line has exceeded 90%. In the core evaporation plating process, which is the most technologically intensive, Shenzhen Tianma has also adopted a series of cutting-edge equipment to compete with international large factories on the same platform.
Display Supply Chain Consultant (DSCC) recently released a forecast report stating that global OLED panel shipments will decline by 1% year-on-year in 2023, and the overall shipment amount will decline by 7% year-on-year to $38.7 billion.
Specifically, in 2023, the shipment volume of OLED panels for smartphones will decline by 8% year-on-year, and the shipment volume will remain unchanged; The shipment volume of OLED panels for television will decrease by 15% year-on-year, and the shipment volume will decrease by 12%.
In terms of manufacturer rankings, Samsung Display (SDC) is expected to continue to dominate the OLED panel market with a market share of over 50%. SDC will become the only manufacturer to supply four OLED panels for the Apple iPhone 15 series. In 2023, SDC will have a 60% market share in the shipment of OLED panels for the iPhone 15 series.
DSCC indicates that the market share of LG Display (LGD) OLED panels is expected to slightly increase from 20% in 2022 to 21% in 2023. LGD is a panel supplier for iPhone 14 and iPhone 14 Pro Max. In 2023, LGD accounted for 22% of iPhone 15 series OLED panel shipments, which is higher than 17% of iPhone 14 series. This is mainly because LGD supplies LTPO OLED panels for iPhone 15 Pro and iPhone 15 Pro Max.
In addition, the market share of Chinese manufacturer BOE in the OLED panel market is expected to increase from 9% in 2022 to 13% in 2023, making it the third largest manufacturer in the world. In 2023, BOE accounted for 18% of the iPhone 15 series OLED panel shipments, which will show a significant increase compared to 10% of the iPhone 14 series.
As is well known, the OLED ization of smartphones is becoming increasingly evident. According to data, the proportion of OLED screens in all smartphones is as high as 50%, and this proportion may increase to 70%, 80%, or even 100% in the future.
Why do people use OLED screens? The reason is that OLED screens are more energy-efficient and display better than LCD screens. At the same time, COF packaging can be used to achieve narrower borders, and can also be used for folding, curved screens, and so on.
Currently, there are many manufacturers providing OLED screens for smartphones, but the main ones are Samsung, BOE, LG, Vicino, and others. Among them, Samsung is the most impressive, accounting for almost 70% or more of the market share in 2021.
Then there is BOE, with a market share of about 9%, followed by LG, with a market share of about 7%. These three major manufacturers account for nearly 90% of the market share, leaving little market for other manufacturers.
OLED screens require OLED screen driver chips, and the current process is mainly 28nm~45nm.
And there are not many manufacturers producing OLED screen driver chips for mobile phones. Currently, the global manufacturers that can produce OLED DDI are mainly TSMC, Samsung Electronics, UMC (Lianhua Electronics), American Gexin, and SMIC.
But in terms of OLED driver chips for mobile phones, there are mainly three manufacturers, namely Samsung, LX Semiconductor, and Novatek.
According to data from the first quarter of 2022, Samsung accounted for another 55% of the OLED screen driver chips in mobile phones, followed by LX Semiconductor, with a share of approximately 14.6%. Novatek has a share of 11.6%.https://www.stoneitech.com/
