[UBI Research China Trend Report] Will BOE Provide UPC Panel with Transparent PI Substrate to Oppo?

/in , /by

BOE, the largest display maker in China, produces UPC (Under Panel Camera) panels with transparent PI substrates.

UPC is a technology that makes a full screen of a smartphone possible by placing the front camera under the screen. The UPC technology that is currently commercialized is a method of patterning the cathode electrode and changing the resolution near the camera. However, this time it is expected that a transparent PI substrate will be additionally applied to the UPC panel supplied by BOE to Oppo.

Existing transparent PI substrates had difficulties in mass production due to the high process temperature of LTPS TFT. Yet, the recent test results of the panels with the transparent PI substrate produced by BOE reached most conditions of satisfactory levels even at the LTPS TFT process temperature.

The UPC OLED panel with the transparent PI substrate developed by BOE is expected to be installed in Oppo’s upcoming products.

Samsung Display is using UTG(Ultra Thin Glass) for the cover window and most Chinese panel companies are using Colorless PI. Many Chinese companies are introducing foldable phones, but durability issues are reported on many social network media posts. Chinese panel makers still have much to go in terms of quality in technology and production cost when compared to Samsung Display.

 

What’s the change for full screen implementation?

/in /by

After Apple launched iPhoneX, applied with notch OLED to implement a wider full screen in 2017, many smartphone makers such as Huawei, Vivo and Oppo started to introduce similar types of smartphones.

 

The total number of notch-type OLED smartphones, which have been revealed since 2017, is 36, accounting for 10% of total OLED smartphones.

The reason why smartphone makers apply notch-type display is to provide consumers with the large screen size in a limited phone size. However, in the notch type, there is a limitation in expanding the display area (DA), which is the ratio of the display to the smart phone, due to the camera and the front speaker. Thus, the smartphone makers seem to implement the camera function with adopting a popup method.

On June 12, Vivo introduced the smartphone NEX with DA 91.2%.The camera is embedded in the device in the form of a pop-up, and the display itself serves as a speaker and fingerprint sensor. By minimizing the bezel, Vivo achieved a full screen.

Oppo showcased Find X in Paris, France on June 19. Oppo also adopts the camera function as a pop-up method, similar to Vivo, to implement a full screen. It has a 3D face recognition sensor. DA of Oppo’s Find X is 93.8%, which is about 2.7% larger than that of Vivo. This is about 10% larger than Samsung Electronics’ Galaxy S8 +, which had the biggest DA in 2017, and 11% larger than iPhone X.

Analysis of the average DA from 4Q 2017 to 2Q 2018 after the launch of the Notch model, shows that the notch type DA is about 9% and the camera pop type DA is about 17 % wider than that of the conventional smartphones (excluding notch type). By switching the front camera into a pop-up form, more than 90% DA can be realized.

As such, smartphone makers are making various changes to realize full screen. There is a growing interest in how to minimize the bezel for the launching a smartphone with a wider DA.

full screen 구현을 위한 변화, 어디까지?

/in /by

2017년 Apple이 더 넓은 full screen을 구현하기 위해 노치형태의 OLED를 적용한 iPhoneX를 출시한 이후, Huawei와 Vivo, Oppo 등 다수의 스마트폰 업체들이 유사한 형태의 스마트폰을 잇따라 출시하기 시작하였다.

2017년부터 지금까지 공개된 노치형태의 OLED 스마트폰은 총 36종으로 전체 OLED 스마트폰의 10%를 차지한 것으로 분석된다.

스마트폰 업체가 노치형태의 디스플레이를 적용한데에는 제한된 스마트폰 크기에서 최대한 큰 화면을 소비자에게 제공하기 위한 것으로 풀이된다.

그러나 노치형태는 카메라와 전면 스피커로 인해 스마트폰에서 디스플레이가 차지하는 비율인 DA(display area)를 확장시키는 데에 한계가 있어, 스마트폰 업체는 카메라를 팝업 형태로 구현하는 방식을 채택하고 있는 것으로 보인다.

지난 12일 Vivo는 DA가 91.2%인 스마트폰 NEX를 공개하였다. Vivo는 카메라는 팝업 형태로 기기에 내장하고, 디스플레이 자체가 스피커와 지문 인식 센서 역할을 하는 것으로써 베젤을 최소화하여 full screen을 구현하였다.

Oppo는 19일(현지시간) 프랑스 파리에서 Find X를 공개했다. Oppo 또한 full screen을 구현하기 위해 Vivo와 마찬가지로 전면 카메라를 팝업형태로 적용하였으며, 3D 얼굴인식센서를 갖췄다. Oppo의 Find X의 DA는 93.8%로 Vivo대비 약 2.7%가 커졌다. 이는 2017년 가장 큰 DA를 가졌던 스마트폰인 Samsung Electronics의 Galaxy S8+ 대비 약 10%, iPhone X 대비 11% 가량 넓어진 것이다.

<Vivo NEX와 Oppo Find X, 출처: netmag.pk, GSMArena>

노치형태가 출시 된 2017년 4분기부터 2018년 2분기까지의 형태별 평균 DA를 분석해보면, 기존 스마트폰(노치형태 제외) 대비 노치형태의 DA는 약 9%, 카메라 팝업형태의 DA는 17% 가량 더 넓어진 것으로 나타났다. 전면 카메라를 팝업 형태로 전환함으로써 90%이상의 DA구현이 가능해진 것이다.

이처럼 스마트폰 업체들은 full screen 구현을 위한 다양한 변화를 시도하고 있다. 어떠한 방식을 통해 베젤을 최소화하고 보다 넓은 DA를 가진 스마트폰을 출시할지 관심이 집중된다.

OLED smartphones launched in the first quarter of 2018 exceeded the average DA 80%

General Class AMOLED Panel Estimated to be Extensively Supplied. How Will it Affect OLED Industry?

/in /by

Only 2 models of smartphone with the general class AMOLED panel were released in the first 2 quarters of 2015. However, as 5 more models were revealed until August in the third quarter, it is expected that demand for general class AMOLED panel will gradually increase.

 

Currently 7 companies, including Samsung Display, are mass producing or aiming to mass produce small to medium-sized AMOLED panel of rigid type. China’s EDO or Taiwan’s AUO are believed to be producing in small quantity for samples. Other Chinese companies are also aiming to mass produce AMOLED panel but satisfying the current demand is analyzed to be difficult. At present, Samsung Display is the only panel company that can meet the demand for general class AMOLED panel by set companies. There is much interest in whether AMOLED industry can rebound with the Samsung Display’s movement in the second half.

 

It is expected that Samsung Display will increase operation rate of A1 and A2 rigid lines in the second half in order to meet the demand for general class AMOLED panel. Following this, emitting material companies’ sales increase is also anticipated and positively affect management of AMOLED industry’s ecosystem.

 

If the demand for general class AMOLED panel is higher than expected, there are some who believe that additional investment for A3 line could be for hybrid structure that can switch between rigid and flexible rather than flexible exclusive line.

 

There is much focus on how Samsung Display’s mass production and supply plans for general class AMOLED panel will affect the AMOLED industry growth.

보급형 AMOLED panel 공급 본격화 예상, OLED 산업에 미칠 영향은?

/in /by

2015년 1사분기와 2사분기에 출시된 보급형 AMOLED panel을 적용한 스마트폰은 2종에 불과했지만 3사분기에 들어서며 8월까지 5종이 공개되어 보급형 AMOLED panel에 대한 수요가 점차적으로 증가할 것으로 전망된다.

현재 rigid type의 중소형 AMOLED panel을 양산 또는 양산을 목표로 하고 있는 업체는 Samsung Display등 7개 업체이다. 중국의 EDO나 대만의 AUO는 샘플수준으로 소량 생산을 하고 있는 것으로 알려져 있고 다른 중국 panel 업체들도 올해 AMOLED panel 양산을 목표로 하고 있지만 당장의 수요를 충족시키기에는 어려울 것으로 분석된다. 보급형 AMOLED panel을 요구하는 set 업체들의 수요를 충족시킬 수 있는 panel업체는 현재 Samsung Display가 유일하다. 따라서 하반기 Samsung Display의 움직임에 AMOLED 산업이 다시 한번 탄력을 받을 수 있을지 기대를 모으고 있다.

Samsung Display는 보급형 AMOLED panel의 수요를 맞추기 위해 하반기 A1과 A2 rigid line의 가동률을 끌어 올릴 것으로 예상되며 이에 따라 발광재료 업체들의 재료 매출 증가도 기대되어 AMOLED 산업의 eco-system 유지에 긍정적인 영향을 미칠 것으로 전망된다.

또한 보급형 AMOLED panel의 수요가 예상보다 높아질 경우 A3 line에 대한 추가 투자가 flexible 전용이 아닌 rigid와 flexible 전환이 가능한 hybrid 형식으로의 투자가 될 수 있다는 전망도 나오고 있다.

하반기 Samsung Display의 보급형 AMOLED panel 양산과 공급 계획에 따라 AMOLED 산업 성장에 탄력을 줄 수 있을지 기대된다.

2015년 8월까지 출시된 보급형 AMOLED panel이 적용된 스마트폰
