Q2 OLED Supply/Demand Update – Oversupply to Persist

Published July 6, 2021

We have updated DSCC’s Quarterly OLED Supply/Demand and Capital Spending Report for Q2 2021, with DSCC’s latest capacity outlook for the industry and our forecast for OLED panel demand. As we have reported for more than a year now, OLED for smartphones (technically, for small & medium applications) continues to have a substantial oversupply which is expected to persist for years. We have revised our outlook for OLED TVs on both the supply and demand sides. We continue to expect a modest oversupply in 2021-2025 with utilization below 90%, but above 80% throughout the forecast period.

The report combines DSCC’s comprehensive view of OLED capacity with our equally thorough analysis of OLED demand and compares supply and demand for both smaller screens and large-gen sizes. DSCC’s OLED capacity outlook extends to 2025 and covers the capacity for 104 different phases of OLED capacity investments, over 13 different panel makers and details the supply capacity of the industry by manufacturer, by country, by substrate type (flexible/rigid), deposition type, backplane type, color type and form factor.

The report includes two separate views of capacity, DSCC’s “aggressive” capacity case, which includes all possible fabs, and our “conservative” case, which includes only fabs in our A, B and C groups. Group C fabs have equipment POs issued more than a year in the future but are considered high probability (>>50%). The conservative case excludes D group fabs, which are considered as less than 50% probable, and since even the conservative case leads to a conclusion that the industry will have oversupply for years, it must be considered as more likely.

In both smartphones and TVs, OLED capacity today is dominated by Korean panel makers Samsung and LGD, respectively. Capacity additions in China, including not only Chinese panel makers, but LGD’s addition in Guangzhou, have increased China’s share of capacity from 5% in 2017 to an expected 42% in 2021. Continued investments by both SDC and LGD will allow Korea to maintain its lead through 2024, but TV projects by both CSOT and BOE will mean that China’s capacity will narrowly overtake Korea in 2025.

While LGD will continue to lead in OLED TV capacity throughout our forecast, capacity additions by Samsung, BOE, and CSOT will reduce LGDs share of capacity from 100% in 2020 to 52% in 2025, as Samsung grows to 26% of industry capacity.

In Small/Medium OLED, Samsung’s share of capacity will continue its steady decline as their capacity sees modest reductions in 2020-2022 associated with the introduction of Y-OCTA, while Chinese panel makers aggressively add capacity. Samsung capacity share was from 88% in 2017, but already dropped to 58% in 2020 and will further decline to 39% in 2025. BOE passed LGD in 2020 to become the #2 supplier by capacity, and LGD will be passed by CSOT and Tianma in 2025 to fall to the #5 position.

While input area is important, especially for materials suppliers, the supply/demand outlook is shaped by the product mix and yield. The report works through the details of fab ramps, yield curves, and product mix to estimate the total industry output as shown in the figure below. In the report, we segregate foldable products into two groups, with the Foldable2 group representing larger foldable products such as notebooks and tablets, while Foldable represents smartphones. Our report reflects the reality in the industry that yields on OLED smartphone products are lower than expected for all panel makers except Samsung Display. But our forecast anticipates continued yield improvements as panel makers progress through the experience curve.

The DSCC demand forecast includes 11 different applications, and the details are available in DSCC’s Quarterly OLED Shipment Report​ (see separate story this issue). The OLED Supply/Demand report includes a summary of our forecast by application.

In working out the total supply/demand balance, we need to work in area terms, and our forecast for OLED display panel area by major application is shown in the next chart. While smartphones represented the largest display area in 2020, we expect TV to surpass smartphones in 2021 and eventually grow to 47% of all area demand by 2025. While the area demand for “all other” applications climb to 10% of the total, driven by IT applications (monitors, notebooks and tablets), and smartphones fall to 43% of OLED area demand.

Now putting that together into the supply/demand picture, the final chart shows our outlook for smartphones for OLED panels, combining Rigid OLED and Flexible OLED. We expect OLED smartphone overcapacity to continue out to 2025, but the magnitude of the oversupply to diminish from 44% in 2020 to 18% in 2025. The picture for rigid OLED is better, and that for flexible is worse. But the dividing line between rigid and flexible will become blurry, as we expect BOE, LGD and perhaps other panel makers to make rigid panels for notebook PCs on flexible lines starting in 2022-2023.

On the TV side, we expect that LGD’s overall OLED TV fab utilization in 2021 will fall to 86%, up compared to 2020 but down compared to 90%+ capacity from 2016-2019. We expect UT% will remain in the range of 85%-90% throughout the forecast period, as LGD, SDC and later BOE and CSOT balance capacity increases with price reductions.
