What is the future change of WRGB OLED to respond to QD-OLED?

 

2As Samsung Display’s QD-OLED begins to be applied to TVs and monitors in earnest in 2022, technological changes are being detected for LG Display’s WRGB OLED, which has been leading the large OLED market.

LG Display’s WRGB OLED has produced a WBC structure consisting of two blue layers and one red+yellow green layer in Paju by the end of 2021, and a WBE structure consisting of two blue layers and one red+green+yellow green layer in Guangzhou. Deuterium substitution technology was applied to the blue of the WBE structure.

Since 2022, LG Display has stopped producing WBC panels from its Paju line and has been producing ‘OLED.EX’ panels with deuterium substitution technology applied additionally to green of WBE produced in Guangzhou.

At SID 2022, LG Display also exhibited a large OLED panel with micro lens array technology. Micro lens array technology was applied to Samsung Electronics’ ‘Galaxy S Ultra’ series, and it is the first technology applied to large OLEDs. LG Display is known to expect a 20% improvement in luminance compared to the previous one by applying micro lens array technology. Panels which micro lens array technology is applied are expected to be produced in Paju from the second half of this year.

Lastly, it is known that LG Display is developing a structure in which yellow green is removed from WRGB OLED. By eliminating yellow green, material and processing costs can be saved, and color gamut is expected to be improved.

Attention is paid to how LG Display’s WRGB OLED will evolve to compete against QD-OLED.

[2022 OLED KOREA CONFERENCE] LG Display’s OLED 3.0 Captures Brightness and Lifespan Simultaneously

At the keynote session of UBI Research’s ‘2022 OLED Korea Conference’ held from April 6th to 8th, Sang-Hyun Ahn, Managing Director of LG Display, announced, ‘The Present and Future of Automotive OLED Display: LG Display’s Future Outlook’.

Director Ahn announced, “The future will transform people and vehicles, and vehicles and vehicles to be connected, autonomous, shareable, and electrically driven. In order to respond to these changes, vehicle displays are getting bigger and more diverse in design, and displays are being applied to various locations to provide sights and information”.

Director Ahn continued, “The automotive display industry was led by LCD, but the OLED market is also gradually expanding its area.” He predicted, “The automotive OLED market will be worth $1.2 billion in 2025, It is also possible to grow to $6 billion.”

In addition, Director Ahn said, “LG ​​Display has already introduced an OLED 1.0 structure that satisfies the minimum requirements for automotive display: brightness of 800 nits and lifespan of 10,000 hours. Unlike OLED for smartphones, OLED for automobiles requires brightness of 800 nits or more to grasp accurate information even during the day, and lifespan of 10,000 hours or more is essential because the use cycle is more than 10 years. Although there is a trade-off between brightness and lifetime, we plan to develop OLED 3.0 with a brightness of 1,000 nits or more and a lifetime of 10,000 hours or more by overcoming this through development of materials and structures.”

Lastly, Director Ahn mentioned about future displays such as extra-large and transparent, slidable, and rollable that are applied to vehicles and said, “Many companies want large and many screens, but they want to hide those screens inside the vehicle. Slidable panels, which can be a solution to this, are already technologically stable and can become common around 2025. On the other hand, rollable panels, such as those that come down from a vehicle sunroof, still have a long way to go, but we will continue to develop them.”

[2022 OLED KOREA CONFERENCE] Samsung Electronics Joins the OLED TV Market, and the TV Panel Market is Expected to Exceed 20 million Units in 2025

At UBI Researchs 2022 OLED Korea Conferenceheld on April 6th-8th, UBI Research CEO Choong-Hoon Lee gave a presentation on,OLED Market Review.

CEO Lee presented the status of the entire OLED industry, market, and outlook with a focus on issues in 2022.

CEO Lee first announced the OLED TV business, a major issue in the recent OLED industry. CEO Lee said, “The biggest issue that has been heating up the OLED industry since the end of last year is OLED TV. There are topics such as Samsung Display’s re-entry into the large OLED business, sales of QD-OLED TVs between Samsung Electronics and Sony, and visualization of collaboration between Samsung Electronics and LG Display.”

In the TV OLED panel demand and supply forecast, CEO Lee said, “If Samsung Electronics purchases OLED panels from LG Display and conducts OLED TV business, LG Display and Samsung Display can supply a total of 12 million TV OLED panels this year. Among them, demand is 11.7 million units, and oversupply accounts for only 3%.” In addition, “With the joining of Samsung Electronics, the demand for OLED TV panels is expected to expand to 13 million units in 2023 and 20 million units in 2025. According to the expanding market, companies need to expand their facilities by the third quarter of this year” he predicted.

CEO Lee continued, “LG ​​Display has been working hard to secure funds for 8.5 generation OLED line expansion since last year, and it is estimated that it will secure additional funds for 45K expansion within this year. With LG Display’s additional measures, the TV OLED panel market is expected to reach 13.5 million units in 2023 and 16 million units after 2024. However, to secure a market of more than 20 million units, it is necessary to plan to invest in the 10.5 generation by next year” he analyzed. He also said, “If Samsung Display invests, 10.5G investment is desirable, but 8.5G investment is expected.” He said, “Whether LG Display invests or Samsung Display invests, a long-term supply contract with Samsung Electronics for 10.5G investment should take precedence. If the investment proceeds, Samsung Display is expected to secure its own funds, but LG Display is expected to require joint investment with Samsung Electronics.”

[2022 OLED KOREA CONFERENCE] What New Technology Will Advance OLED for Mobile Devices?

At UBI Researchs 2022 OLED Korea Conference Tutorialheld on April 6th-8th, Dr. Jae-Jin Yoo from the Department of Electrical and Computer Engineering at Seoul National University gave a presentation on,An Overview of OLED Materials and Devices.

Dr. Yoo explained the paradigm and market prospect of OLED for mobile devices, the structure of each layer, and the light emitting material. Although LCD is still leading the market by introducing mini-LED and other technologies, it is predicted that OLED will lead the display market in the future.

Dr. Yoo explained that among the latest technologies, “LTPO TFT is a technology newly applied to mobile by supplementing the shortcomings of LTPS TFT and oxide TFT process. LTPO TFT is a double-designed display with low electron mobility but no leakage current by changing at least one transistor to oxide in the LTPS TFT process”. He also explained, “In still images, LTPS TFT needs to be driven at 60Hz to maintain the brightness of the screen due to high leakage current, but for oxide TFTs, 1Hz operation is possible because of low leakage current.” Dr. Yoo added, “Although there is an issue that the process of LTPO TFT is more complicated than that of LTPS TFT, it can reduce the total power of mobile devices by 10~15% and it has the advantage that it can be applied to AOD (Always on Display).”

Next, introducing the OLED deposition method and vapor deposition machine, he explained that if the 8.5 generation vertical deposition method, which is currently an issue for IT, is commercialized, it has many advantages in terms of productivity and is a much anticipated technology.
