/in , /by

Of the 122 OLED smartphones released in the first half of 2021, 119 6-inch smartphones were released, occupying an overwhelming share of 97.5%. Compared to the 6-inch smartphones released in 2018, which accounted for 78% of the total, it has become the mainstream of the smartphone market in just three years. One 5-inch model and two 8-inch models were released, and the 7-inch model was not released. The 5-inch model is Asus’ Zenfone8, the 8-inch model is Xiaomi’s Mi Mix Fold, and Huawei’s Mate X2.

By display design, hole model was released the most with 103, followed by notch model with 13 and narrow bezel model with 6. As in 2020, products with a home button were not released.

Looking at the distribution by resolution, 400~500ppi products were released the most with 64, accounting for 52.5% of the market share, 48 products with less than 400ppi and 10 products with more than 500ppi. The highest resolution product was Sony’s Xperia 1 II, which recorded 643 ppi.

In the display area (D.A), which is the ratio of the display to the size of the smartphone, products belonging to 80-90% accounted for 84.4%, 13.9% of those over 90% and less than 80% were not released. This is analyzed as a result of the disappearance of the home button and the continuous release of full-screen smartphones. The product with the highest D.A was 94.1%, which was occupied by Huawei’s Mate 40 Pro 4G, followed by Huawei’s Nova 8 pro in second place and Honor’s View40 in third place.

Finally, by country, China released the most with 104, followed by Korea with 12, Taiwan with 4, and Japan and Germany with 1 each.

[Press Release] AMOLED components and materials market grew to $ 24.15 billion in 2023

Although Samsung Electronics and Apple’s OLED smartphone market are stalled, Chinese smartphone makers are gradually increasing their use of OLEDs based on the huge smartphone market in China. As a result, BOE and Chinese panel makers have aggressively established a Gen6n flexible OLED plant, which is driving the OLED industry.

As a result of UBI Research’s panel makers’ operation rate analysis due to OLED plant expansion and supply and demand, the market for various component materials (excluding light emitting materials) that make up OLEDs is expected to reach $13.9 billion in 2019 and expand to $ 24.15 billion in 2023.

Recently, as the production of foldable OLED has started, various kinds of films that are not applied to LCD are emerging as core materials.

In the [2019 OLED Components and Materials Report] published by UBI Research, we examined the foldable OLED structure of Samsung Display, LG Display, and BOE, and analyzed the thickness and characteristics of the films that make up the module.

In the OLED components and materials market, components for TV OLEDs will grow rapidly to reach $ 19.1 billion in 2023 and lead the OLED industry.

LCD Smartphone is 4K era, what about OLED Smartphone?

/in /by

In the past MWC 2017, Sony unveiled the world’s first Smartphone with 4K LCD and it is scheduled to release the Xperia XZ2 Premium with 4K LCD on July 4. Attention is growing whether 4K resolution market is to be launched in earnest in smartphones.

TV market is already moving beyond the 4K to the 8K. Samsung Electronics and Sharp released new TVs with 8K resolution in the first half and Sony plans to release 8K TVs in the second half. LG Display also exhibited 88inch 8K OLED TV at CES 2018. As such, 8K TV is entering the premium TV market, and smart phones are expected to increase the number of products with 4K resolution in response to the higher resolution of TVs.

In the Smartphone, 4K has been implemented in LCD; however, in the case of OLED, QHD resolution is still dominant for the 4 consecutive years.

This is because there are many restrictions on the fine metal mask (FMM) technology that is being applied to OLED manufacturing. The thickness of FMM applied to the current production is about 20 ~ 30um. For 4K fabrication, the thickness should be as thin as 10um, but it is difficult for existing FMM manufacturing method.

As a result, FMM replacement technologies are being developed for high resolution implementation. Typical technologies under developing, include laser FMM patterning with laser, electroforming manufactured by electroplating method, a fine hybrid mask that is used to form a frame by electroplating on a film and pattern the film with a laser, and a surface source that realizes a high resolution by vertically setting the deposition incident angle.

Deposition technologies for high-resolution manufacturing at various exhibitions and conferences are being introduced. Depending on the availability for securing mass production, it is expected to see not only 4K OLED Smartphone, but also high-resolution AR and VR devices of RGB method.

LCD 스마트폰은 4K시대, OLED 스마트폰은?

지난 MWC 2017에서 소니가 세계 최초로 4K LCD를 탑재한 스마트폰을 공개한데 이어 오는 7월 4K LCD가 탑재된 Xperia XZ2 Premium을 출시할 예정으로 스마트폰에서도 4K 해상도 시장이 본격적으로 열릴 것으로 기대되고 있다.

이미 TV시장에서는 4K를 넘어서 8K 시장으로 옮겨가고 있는 중이다. 삼성전자와 샤프는 상반기 8K 해상도의 TV 신제품을 공개하였으며, 소니도 8K TV를 하반기 출시 예정이다. LG Display에서도 88inch 8K OLED TV를 CES 2018에서 전시를 하였다. 이처럼 8K TV가 프리미엄 TV 시장에 진입을 하면서 스마트폰도 TV의 고해상도화에 대응하여 4K 해상도를 가진 제품 출시가 증가할 것으로 예상된다.

하지만 스마트폰에서 LCD는 4K를 구현했지만 아직 OLED는 4년째 QHD 해상도에 머물러있는 상황이다.

OLED제조에 적용되고 있는 FMM(fine metal mask) 기술에 제약이 많이 있기 때문이다. 현재 양산에 적용되고 있는 FMM의 두께는 약 20~30um 수준이며, 4K 제조를 위해서는 두께가 10um 수준으로 얇아져야 하지만 기존 FMM 제조방식으로는 어려움을 겪고 있는 상황이다.

이에 따라 고해상도 구현을 위한 FMM 대체기술들이 개발되고 있다. 대표적인 기술로는 레이져로 패터닝을 하는 laser FMM과 전주도금방식으로 제조하는 electroforming, 필름에 전주도금으로 프레임을 형성하고 레이져로 film을 패터닝하는 fine hybrid mask, 증착 입사각을 수직으로 하여 고해상도를 구현하는 면소스 등이 개발 중에 있다.

 

각종 전시회와 학회에서 고해상도 제조를 위한 증착기술들이 공개되고 있는 추세이며, 양산성 확보여부에 따라 앞으로 4K OLED 스마트폰, 더 나아가 RGB 방식의 고해상도 AR, VR 기기를 볼 수 있을 전망이다.
