What’s the change for full screen implementation?

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?

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.

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.

Since the first Galaxy S by Samsung Electronics in March 2010, 9 types of Galaxy S Series were launched. For the past 6 years, screen size increased by 1.5 inch and resolution improved by approximately 10 times.

According to the AMOLED Characteristics Analysis Report of Galaxy S Series recently published by UBI Research, the AMOLED panel of this series from Galaxy S to Galaxy S7 Edge increased in size from 4 inch to 5.5 inch. The resolution increased by 9.6 times from 480 x 800 WVGA to 1440 x 2560 QHD. The Galaxy S Series AMOLED progress suggests the Galaxy S8, expected to be released in 2017, will have screen size of mid-to-high 5 inch mark with the resolution of 4K UHD (800 ppi).

Since the 4 inch early model of Galaxy S in March 2010, the screen enlarged each year to 5.1 inch and 5.5 inch for S7 and S7 Edge respectively, over approximately 30% increased screen size compared to the early S model. Samsung Electronics had released 6 inch mark smartphone. However, in 2015, the 6 inch mark products disappeared and 5 inch mark screen size occupies 71% of the total smartphone products by Samsung Electronics.

During this period, Samsung Electronics released products with diverse resolutions from Galaxy S’ WVGA to S6 and S7’s QHD through S3’s HD and S4 and S5’s FHD. With the exception of S3’s HD, Galaxy S Series resolution is moving forward every 2 years at present. If this speed of development continues, the Galaxy S8, expected to be released in 2017, could be equipped with screen size of mid-to-high 5 inch mark and resolution of 4K UHD.

UBI Research explained that Samsung Display’s 5.5 inch UHD 4K 806 ppi AMOLED for VR device that was shown in the recent SID 2016 has the same brightness as S7. He added that considering production yield, the display is expected to be used for Galaxy S8 to be released next year.
