DSCC Advanced TV Cost Report Allows Comparison of QD-OLED Cost with WOLED and MiniLED

DSCC has released its latest update of our Advanced TV Display Cost Report (一部実データ付きサンプルをお送りします), with updates to OLED and LCD cost profiles. This quarter’s edition includes updates to all sizes of WOLED panels and 55”+ LCD sizes including LCD with MiniLED backlights, and cost profiles for 55” and 65” QD-OLED panels from SDC.

The cost report provides detailed cost profiles of 142 distinct LCD products, including combinations of screen size, refresh frequency (60Hz/120Hz), backlight (conventional /QDEF/MiniLED), gen size and manufacturing location (Korea / China) and including open cell models. The report covers 36 distinct OLED products, ranging in size from 27” to 97”, with resolutions from FHD to 8K, and manufactured on Gen 8.5 and Gen 10.5 in China and Korea.

LGD is continuing to improve production at its Gen 8.5 White OLED (WOLED) fab in Guangzhou, China. While our cost report shows that total panel costs from China production in 2020 were higher than the costs for comparable panels made in Korea, by 2021, the advantages for China production allowed lower total costs, and by 2022 Korea’s yield advantage has been eliminated. China has lower costs for personnel, indirect and SG&A, but higher costs for depreciation compared to Korea’s fully depreciated lines. So total costs for the two regions are comparable, but cash costs are lower for production in China.

In the last two years, LGD has greatly increased the range of screen sizes for WOLED products, and our report covers additional monitor products to be introduced in 2022, including 27” FHD, 31” QHD and 42” UHD panels and a 45” WQHD panel with an ultra-wide (21.5:9) aspect ratio. This size panel and the ultra-wide aspect ratio allows an efficient 10-cut on a single Gen 8.5 substrate.

The 45” WQHD panel will be targeted at the high-end gaming monitor market, where its deep contrast and fast response time are key features compared to LCD-based displays. The addition of this 45” panel and additional monitor sizes like 27”, 31”, 42” can allow LGD to generate more revenue from its Gen 8.5 capacity.

In this report we include a new cost model for Inkjet Printed (IJP) OLED. We expect that CSOT will be the first panel maker to introduce IJP OLED with capacity starting in 2024. CSOT has a joint development agreement with JOLED for IJP technology and has demonstrated IJP OLED models at various exhibitions. A comparison of the costs for IJP OLED with WOLED is shown in the next charts here. Both types will be made on Gen 8.5 lines in China.

We assume in our cost model that the IJP panel has an RGB pixel structure, compared to RGBW for WOLED. This reduces the costs for module components like driver ICs. We also assume that IJP panels do not require a color filter, giving an additional cost savings. Most early prototypes of IJP OLED have included color filters. The charts here demonstrate that even with these advantages, the cost for IJP is comparable to WOLED, and when WOLED lines are fully depreciated the total cost for WOLED can be even lower than IJP.

Starting in 2022, we include QD-OLED panel cost in this report. We estimate that in its year of introduction, QD-OLED panel costs are dramatically higher than any other flat panels of the same screen size due to relatively low yields. Although SDC has reportedly improved yields for QD-OLED during the course of the year, our yield estimates for 2022 are about 70% for 55” and 65” TV panels.

The costs for QD-OLED panels will come down sharply as yield improves. We estimate that QD-OLED panel costs will decrease by 20%-25% Y/Y in 2023, primarily based on the impact of higher yields. Higher yields allow for fixed costs, which include depreciation and most personnel and indirect costs to be amortized over higher volumes.

Subscribers to the report can see the detailed cost models for 55” and 65” QD-OLED panels, including quarterly cost estimates from 2022 through 2026 with breakdown by cost components and the corresponding estimates of yield and fab utilization.

The latest report updates the cost models for LCD panels with MiniLED backlights. The report allows for comparison across the wide range of performance (and cost) within LCD, from conventional LCD with 60Hz refresh to 120Hz to QDEF panels and finally MiniLED + QDEF. Combined with the OLED cost models, the report allows a complete comparison of the cost of all large-screen TV types.

The next chart here shows the cost profiles for 75”/77” panels across the range of technologies on the market in 2022. LCD products are made on Gen 10.5 lines in China while WOLED products are made with MMG on Gen 8.5 lines in China. Conventional LCD with UHD resolution and 60Hz refresh rates have the lowest cost, more than 50% lower than WOLED UHD made in China. LCD step-up products with 120Hz and QDEF add only a modest cost, roughly 5% and 10% respectively. MiniLED UHD and 8K QD LCD are both substantial cost adders, increasing total costs by roughly 50% each individually, and when combined the 75” 8K MiniLED LCD TV panels have a total cost nearly as high as 77” WOLED UHD panels made in China with MMG.
