At the ‘OLED settlement seminar for the first half of 2022’ held at COEX on June 23, Merck’s Kim Jun-ho, head of research institute, said, “The concept of the refractive index of the emitting layer is often applied to the capping layer on the cathode, but now it is also required for HTL” and mentioned that the light extraction efficiency can be improved through the optimized refractive index design of HTL.

Next, Kim said, “Because the refractive index of HTL has a trade-off relationship with the hole transport capacity, it is difficult to adjust the refractive index,” and “Even though it was lowered to 1.77 from 1.85, the light extraction efficiency could be improved by 7% without an increase in the driving voltage or a decrease in electron mobility.”

Recently, panel makers are continuously developing the OLED light extraction efficiency. This is because by increasing the light extraction efficiency, as a result, the battery life can be increased. Representative examples include a high-refractive capping layer and micro lens array, and an on-cell film that removes the polarizer and uses a color filter.
The concept of the refractive index of the light emitting, which had been concentrated on the capping layer, is extended to the common layer, and it is expected that panel makers will intensify technological competition, and that there will be many changes in the supply chain of emitting materials of panel makers in the future.

Choong-Hoon Yi, CEO of UBI Research, “Korean display companies must have price competitiveness as well as OLED technology competitiveness”

Although there is still a gap in display technology between Korea and China, it has been argued that Korean display companies should have price competitiveness as soon as possible.

On the 23rd, at the ‘OLED Settlement Seminar for the first half of 2022’ held at COEX in Samsung-dong, Seoul, UBI Research CEO Choong-Hoon Yi made a presentation on ‘Forecast of the small OLED market, which China is chasing fiercely’.

CEO Yi announced, “Currently, the media reports that the technological gap between Korea and China has almost narrowed, but making and displaying products and mass-producing products are two different things, and the technological gap between Korea and China is still significant.” He continued, “Samsung Display is planning various products such as slideable and Z-folding based on technological competitiveness. However, it will be difficult to commercialize it immediately because the slideable phone invades the existing foldable phone market.”

CEO Yi said, “It is very important not only to develop technological competitiveness, but also to increase price competitiveness. The reason Korean companies closed the LCD business is not because of the good technology of Chinese companies, but because they were pushed back in price competitiveness.”, and “As the technology advances, the performance difference felt by ordinary consumers becomes insignificant, so products with good price competitiveness are inevitable in the market,” he analyzed.

Finally, “China’s OLED industry is growing under the enormous support from the government. In order not to lose the lead in the OLED market like LCD to China, it is essential for domestic companies to prepare for price competitiveness and the government’s support policy,” he concluded.

GrapheneLab, a graphene commercialization technology company, announced that it is possible to manufacture FMMs over 800ppi using graphene.

At the ‘UBI Research First Half 2022 OLED Settlement Seminar’ held at COEX in Samseong-dong, Seoul on the 23rd, GrapheneLab CEO Yong-duk Kwon said, “In the early 2000s, FMM technology, which started in the early 2000s, was not interested in the plating method. It is changing,”, and “After 2013, many patents related to the plating method FMM manufacturing technology have been applied, and it is easier to apply the plating method than the currently used etching method in order to go to high resolution.”

Next, CEO Kwon said, “We moved away from the existing limiting etching method FMM and applied the plating method FMM. Compared to the etching method, where 400ppi was the limit at the same thickness, the plating method realized more than 600ppi.”, “Etched metal mask has a dead zone of 8um in length due to the INVAR structure that becomes sharp like a dot when etching at a depth of 20um, whereas there is no dead zone during pattern plating of the plated metal mask.”

Lastly, CEO Kwon said, “For the MSAP electroforming technology, a low coefficient of thermal expansion with a thin thickness is required. As a result of measuring the coefficient of thermal expansion using TMA on the plated sample, it was measured up to 3.1ppm, and it went down to 2.5ppm without heat treatment.”

iPhone13/Apple

It seems that BOE has started line operations for iPhone 13.
Back in March, most of the iPhone 13 shipments were canceled due to an issue with Apple. BOE will now resume production. With this new development, BOE’s forecast for iPhone 13 production this year is expected to increase after being adjusted down in March.
BOE has a total of 20 iPhone module lines at its B11 (Mianyang) plant. BOE’s production of the iPhone 13 is believed to have begun in early June and production of the iPhone 14 is expected to begin as well. The B11 factory has iPhone 13 line to produce iPhone 12 and 13 and iPhone 14 module line exclusively for iPhone 14, as the process is quite different from iPhone 13 line.
Details of BOE’s iPhone 13 and 14 production volume, panel unit price, and module line by product can be found in UBI Research’s ‘China Trend Report’. UBI Research’s ‘China Trend Report’ can be inquired on the UBI Research website.

1Q of 2022 OLED Emitting Material Market $420 million, up 9% Compared to the Same Quarter of the Previous Year

/in , , , , , /by

According to “2Q22 OLED Emitting Material Market Track”, a quarterly report published by UBI Research, the sales of emitting materials in the first quarter were $421 million, down 21.1% (QoQ) from $533 million in the previous quarter but was an increase by 9% (YoY)when compared to $386 million in the first quarter of 2021.
Although sales of emitting materials for TV and mobile devices decreased compared to the previous quarter, IT sales recorded a meaningful figure of $6.6 million. Although sales fluctuate depending on seasonal demand for applied products, if the sales of emitting materials are analyzed by application product, TV use is gradually increasing.

The top 3 companies in 1Q sales were UDC($86.6 million), DuPont($41.3 million), and Duksan($37.5 million). Duksan became the number one company in sales as a Korean company. The overall sales of luminescent materials in the first quarter decreased compared to the previous quarter but only UDC’s sales increased. Sales decreased to $421.5 million in 1Q22 from $533.8 million in 4Q21. However, UDC’s 1Q22 sales increased to $86.6 million from 4Q21’s sales of $85.5 million. It is estimated that this is due to the rise in the price of rare earth metals, a key material for manufacturing dopant.
Estimated sales of emitting materials in 2022 are $1.77 billion and are expected to grow to $2.4 billion in 2026.
By application product, the projected sales of emitting materials for smartphones this year are $1.4 billion, accounting for 79% of the total.
Of the projected sales in 2026, emitting materials for TV are expected to reach $550 million, which is expected to increase by 23%. In addition, emitting materials for IT are expected to account for 9% of $210 million.

“OLED Emitting Material Market Track” surveys and analyzes the market for quarterly OLED emitting materials. The total market of light emitting materials was identified by examining sales by light emitting layer and common layer.

Chinese Panel Makers in Crisis! Will the Display Business’s Deficit Increase This Year?

/in /by

<Honor 70 With Panels Supplied by Visionox>

Chinese panel makers such as Visionox and BOE are expected to face losses due to cost pressures.
The operation rate of Visionox was analyzed to be high. This is because Visionox is exclusively producing 70-80% of Honor, a large Chinese smartphone manufacturer.
However, despite the high operation rate, Visionox’s business status is precarious at best. Through cooperative efforts, Visionox was allocated most of Honor’s panel production quantity, but it is known that Honor has requested additional panel price reduction. According to some sources, Visionox is currently facing a loss of about 200 million yuan per month due to the reduced panel price.
BOE, the largest panel maker in China is also facing trouble. BOE along with Visionox had previously been in charge of panel production for Honor but received almost no allocation of production volume from Honor. Earlier this year, BOE faced tremendous difficulty due to the cancellation of existing iPhone 13 shipments to Apple. In April, BOE’s CEO Gao Wenbao felt a sense of crisis due to pressure on OLED and LCD volume and price and gave direct orders on cost reduction. Currently, BOE’s OLED line operation rate is less than 40% and it is estimated that the OLED business unit may incur a loss of about 10 billion yuan this year.
LCD, which is one of the main businesses of Chinese panel makers, is continuously falling in prices and the supply and demand of panels from smartphone set makers are sluggish. If an appropriate countermeasure is not found, Chinese panel makers will continue to experience a growing deficit in the display business.
