LTPO OLED backplanes

Low-Temperature Polycrystalline Oxide, or LTPO, is an OLED display backplane technology developed by Apple. LTPO combines both LTPS TFTs and Oxide TFTs (IGZO, Indium Gallium Zinc Oxide). LTPO is applicable for both OLED and LCD displays, actually, but this backplane technology is likely to be used exclusively in high-end OLED displays

In LTPO, the switching circuits are using LTPS while the driving TFTs will use IGZO materials. This could lead to a power saving of around 5-15% compared to the currently-used LTPS backplanes. The main drawback of LTPO, however, is that the IGZO TFTs are larger and so the display density may be compromised.

In September 2014 Apple introduced the world's first device to use an LTPO backplane - the Watch Series 4. Compared to the current-generation Watch, the new series has a larger AMOLED display - 1.78" 448x363 on the 44 mm watch and a 1.57" 394x324 one on the 40 mm model.

KDIA: Korean OLED market share has risen 1.5% in 2025, for the first time since 2015

The Korean Display Industry Association (KDIA) is quoting Omdia, saying that the OLED market share of Korean OLED panels (made by LGD and SDC) have increased 1.5% in 2025, to reach 68.7%. This is the first time since 2015 that Korea's OLED market share has increased. 

The KDIA lists several reasons as to why Korean companies managed to expand their OLED market share last year:

The end of the OLED process monoculture - what will it mean for supply chain companies?

For most of OLED's commercial history, the industry operated as a near-monolith: virtually every panel maker deposited RGB organic materials through a Fine Metal Mask (FMM) on 6th-generation glass (or polyimide substrates with a glass carrier), while LG Display stood as the sole practitioner of its WRGB architecture for large-area OLED production.

In recent years, we have seen the emergence of new OLED architectures, processes and materials that signal the end of this technological uniformity. In this article, we examine the different technologies, speculate how the industry is changing and where it is headed - and understand the implications for supply chain companies.

TCL CSOT reveals it supplies the rollable display for Lenovo's concept laptop

Last month we reported that Lenovo is set to launch its 2nd rollable laptop, that will be called the Lenovo Legion Pro Rollable. It turns out that Lenovo has indeed unveiled this laptop at CES 2026, but it is only a concept device, or a prototype, at this stage.

TCL CSOT confirmed that it is the supplier of the rollable AMOLED, and this seems to be an impressive display, that opens up from a 16-inch display to 21-inch and even 24-inch when fully opened in the ultra-wide configuration you see above. Lenovo and TCL CSOT did not reveal any specifications, beyond the 120Hz refresh rates.

BOE lights up its 8.6-Gen AMOLED line in Chengdu ahead of schedule

BOE officially announced that it has lit up its 8.6-Gen AMOLED production line in Chengdu, five months ahead of schedule. The company aims to be the first in the world to mass produce OLED IT panels in a 8.6-Gen line. 

Back in October, we reported that BOE is accelerating the building of its 8.6-Gen line. The company's original plan was to start mass production in Q4 2026, but now it hopes to begin production in Q3 2026, a month or two earlier than Samsung Display (that also hopes to begin mass production in Q3 2026).

BOE AMOLED shipments to Apple are increasing, its B11 fab is at 73% utilization

According to reports from Korea, BOE's AMOLED shipments to Apple are increasing. BOE is currently shipping panels for Apple standard iPhone models 12 through 16 (including aftermarket panels), and also to Apple's budget smartphones (the iPhone 16e, and reportedly, also the upcoming iPhone 17e).

Apple signs up BOE to supply the majority of its LTPS AMOLED panels for the budget 2026 iPhone 17e

According to reports in Korea, Apple has signed up BOE as the first OLED supplier for its upcoming budget iPhone 17e smartphone, that will ship early in 2026. While BOE will supply the majority of these AMOLEDs, Samsung Display and LG Display are expected to also supply some panels to Apple.

This is a similar distribution that Apple chose for the 2025 iPhone 16e, that sports a 6.1" 1200 nits (peak) 60hz 1170x2532 AMOLED display. It is likely that the iPhone 17e will use a similar panel, and we're quite certain it will not be an LTPO OLED. Apple is aiming to ship around 8 million iPhone 17e devices in the first half of 2026.
