Apple OLED

Apple was the first company to develop LTPO backplanes and it adopted this innovative and energy-efficient backplane technology back in 2018 in the Watch Series 4. LTPO combines Oxide-TFT and LTPS, by using the IGZO in some of the switching TFTs and LTPS in the remaining switching TFTs and all the driving TFTs. LTPO can reduce the power consumption by 5-15%, and enables variable refresh rate.

According to reports from Korea, Apple developed its 2nd-Gen LTPO backplane technology, that uses the IGZO in all the driving TFTs, and uses LTPS only in the remaining switching TFTs. This leads to higher efficiency compared to the first-generation LTPO backplane.

According to UBI Research, the OLED tablet panel market is set to grow quickly, more than doubling between 2024 (12 million units expected) to 2028 (28.4 million). That's a CAGR of 24.1%.

UBI says that the market in 2023 was only 1.8 million panels - so growth in 2024 will be dramatic (almost 7X), mostly thanks to Apple's adoption of OLEDs in some of its iPad modules (expected to be announced next month). Samsung will produce 11" panels for Apple, while LGD will produce larger 12.9" panels. 

UBI Research released its latest foldable OLED shipments forecast, saying that it expects the market to grow from 27.4 million units in 2024 to 52.7 million 2028.

The market is dominated by Samsung Display, which shipped 13.4 million foldable OLEDs in 2023, and holds a 61% market. Samsung is followed by BOE (6.2 million, growing 3X from 2022), TCL CSOT (1.1 million) and Visionox (1.1 million). UBI expects Samsung Display to remain the clear leader in this market as it is the sole supplier to Samsung Electronics - and it is also expected that Samsung will be the exclusive supplier to Apple's future foldable iPhones.

In January 2024 we reported that Samsung Display and LG Display have started to produce AMOLED displays for Apple's future iPads, to be announced later this year. Earlier expectations were for Apple to order a total of 10 million iPad AMOLED displays in 2024 from both LGD and SDC, with LGD getting around 60% of the orders. 

Apple was aiming to launch the new OLED iPads this month, but have now reportedly delayed the release to May, as Samsung is suffering from low yields for the 11" AMOLED panels, mostly due to the tandem stack architecture.

A report from China suggests that Samsung will not produce any AMOLEDs for the upcoming Apple iPhone SE 4, as the Korean maker asked for around $30 per unit (6.1-inch) which was too high for Apple. Apple apparantly wanted to pay only $25, and it is estimated that BOE will supply most of the units, with some orders perhaps going to Tianma.

According to reports, Samsung estimated that it will not be able to make a profit in this project and decided to stop the negotiations when Apple insisted on a low price.

Omdia updated its forecast for Apple's OLED adoption in its IT devices (iPads and Notebooks), saying that the company will begin the OLED transition with the 11-inch and 12.9-inch iPad Pro due later in 2024.

Samsung Display and LG Display will be Apple's suppliers, and the two companies will adopt new technologies. SDC will produce rigid glass based LTPO tandem AMOLEDs and LG will produce flexible AMOLEDs, at its E6 line. Omdia estimates that Apple will pay $80-90 for the 11" displays and $120-130 for the 12.9" displays, without the touch and cover glass (which will add $20-30 per display).

Reports from Korea suggest that Samsung Display and LG Display are starting to produce AMOLED displays for Apple's future iPads, to be announced later this year. Samsung is set to produce 11" LTPO AMOLED displays, while LG Display is producing displays for the 13" model (but LGD will also produce 11" AMOLEDs in the future for Apple). 

The Elec says that both Korean makers developer 11" and 13" displays, but for some unknown reason only LGD will produce the 13" displays. This could change in the future, of course. One reason could be that LG Display has more experience with tandem OLED architectures (developed originally by LGD years ago for automotive OLEDs).

Last month we reported that BOE finally got accepted into Apple's latest-generation iPhone supply chain, and the company will supply 2 million AMOLED displays for iPhone 15 devices in 2023 (that's about 3% of Apple's total iPhone orders). This news came after many years when BOE failed to meet Apple's quality tests.

A new report from China now suggest that BOE's AMOLED displays have been found to still suffer from issues - specifically light leakage around the selfie-camera and sensor 'island'. Eventually Apple decided to cancel its orders from BOE this year, at least until the China-based display maker can fix the issue.
