[田村喜男の補足解説] iPhoneが2021年新モデルでLTPOを本格採用

DSCCは、スマートフォンのセット、パネルその他の主要構成部材の出荷・技術動向の詳細調査レポート Quarterly Advanced Smartphone Features Report (一部実データ付きサンプルをお送りします) を7月13日に発刊、下記グローバルブログにてその分析概要を速報している。今回さらに著書の視点で短く補足解説したい。

Apple Watchに採用されたLTPOの特徴は、移動度が大きく安定性が高いLTPSを利用していること、そしてTFTの均一性が良く、リーク電流が少ないIGZOの利点を一つに結合した技術である。従来のLTPSベースのフレキシブルOLED採用のApple Watchは、時刻を見るたびにスイッチをオンする必要があった。LTPOを採用することにより、デバイスの消費電力を低減し、時計画面の常時オン状態を実現した。 

スマートフォンでは、Samsung GalaxyやSharp Aquos、OppoなどもすでにLTPOを採用しているが、Apple iPhoneでも2021年新モデルでLTPOを採用することになりそうだ。2021年モデル4モデルのうち、6.1” Proと6.7” Pro向けである。これらのLTPOを出荷するフレキシブルOLEDパネルメーカーはSDCのみである。LGDもiPhone向けLTPOパネルを開発中であり、2022年モデルから採用されるようだ。またBOEも開発中であるが、まずはHuawei向けなどが最初の顧客ターゲットとなるであろう。

DSCC’s Quarterly Advanced Smartphone Features Report (一部実データ付きサンプルをお送りします) tracks and forecasts all major product trends in the AMOLED smartphone market, in addition to providing supply chain insights. The report provides a comprehensive listing of historical and forecasts insights through 2025 for panel unit shipments, panel suppliers, brands, device revenues, ASPs, models, screen sizes, resolutions, chipsets and much more for feature segmentations for all AMOLED smartphones.

Several of the major trends identified in the report are the rapid adoption of higher refresh rates, LTPO backplanes and 5G network band.

For higher refresh rates, 90Hz and higher panels are taking significant unit share in 2021, with the 60Hz share falling to 63% share in Q1’21 on a unit basis and 61% share on a revenue basis. 90Hz is holding steady and gained unit share in Q1’21 to 12% and is expected to rise to 19% in Q2’21 as a result of new 90Hz smartphones from Samsung, Vivo and Xiaomi. 120Hz also gained unit share in Q1’21 to 25% from 12% in Q4’20 as a result of smartphone introductions with this refresh rate by Samsung, Vivo, Oppo, Honor and Xiaomi. We expect 120Hz to increase to 29% unit share in Q2’21 and 37% unit share in Q3’21. Samsung has dominated the higher refresh market and is expected to continue to do so until Apple launches the 120Hz iPhone 13 Pro and iPhone 13 Pro Max models. We currently show Apple overtaking Samsung at higher refresh rates in Q3’21 with Apple at 39% revenue share. In Q4’21, we expect Apple at 46% revenue share and Samsung at 29% revenue share. On a model basis, in Q3’21, we expect Apple’s iPhone 13 Pro, iPhone 13 Pro Max and Samsung’s Galaxy S21 FE to be the top three models with higher refresh rates.

This continued demand for higher refresh rates is driven by higher refresh rates required for gaming, a small cost increase, a preference to sell more expensive drivers/panels/smartphones during the driver IC shortage and increased LTPO capacity. The report also reveals the latest LTPO fab schedules by panel manufacturer.

DSCC expects 120Hz to overtake 60Hz by 2022 with 59% unit share and 72% revenue share for the long-term forecast. The >120Hz segment is expected to be small for quite some time as major brands are not working on them. They are likely still a few years away from making large inroads.

As a result of an increase in LTPO capacity, LTPO backplanes on smartphones are also expected to increase. LTPO replaces the LTPS, switching TFT with oxide. Due to its low off current and stable/flickerless operation at low refresh rates, it can significantly reduce power, allow for variable refresh and enable an always on display mode at low power. Refresh rates in LTPO devices can vary from as low as 1Hz to 120Hz, with overall power consumption declining 15% to 20%. DSCC expects LTPO smartphones to reach a 19% panel unit share and 31% smartphone revenue share by Q4’21. This is fueled by Apple launching iPhone 13 Pro and iPhone 13 Pro Max with LTPO backplanes and other flagship phones launching LTPO smartphones.

In addition to the increase in higher refresh rates and the use of LTPO backplanes, DSCC also sees significant growth in 5G. Most 5G smartphones were sub-6 GHz only due to the lack of 5G millimeter wave (mmWave) networks/coverage. mmWave functionality typically resulted in a $100 cost adder on some 5G phones. However, Apple outfitted all US iPhone 12 series products with mmWave + sub-6 GHz without a cost penalty, which is boosting investment in mmWave and its outlook. The US sees the most mmWave investment due to the lack of Sub-6 GHz bandwidth as much of the sub-6 GHz spectrum in the US is still owned and used by the government.

In Q1’21, mmWave + Sub-6 GHz declined 17% from 22% in Q4’20 as Apple’s iPhone 12 models lost share. While the iPhone 12 series was around 35% mmWave + Sub-6 GHz, the iPhone 13 series is expected to be closer to 55% mmWave + Sub-6 GHz as other regions roll out mmWave. Apple is also expected to roll out mmWave to Japan and Korea with the iPhone 13 series.

For the long-term forecast of 5G, AMOLEDs are expected to continue to lead the way in 5G due to their advantages in power, thickness and weight. 5G smartphones are expected to account for 67% of AMOLED demand in 2021, and 92% in 2022 and close to 97% by 2025, helped by a declining price gap between 4G and 5G components and continued network availability. In 2021, 5G demand is expected to grow by 68% to 418M, with 46% unit growth in 2022 to 690M and 10% unit growth in 2023 to 761M. 5G is expected to reach 930M units by 2025.
