Samsung is supposedly gearing up to produce low-temperature polycrystalline oxide display panels for Apple as the company works to introduce 120Hz refresh rates on its higher-tier "iPhone 13" models.

The South Korea tech giant could start producing the LTPO thin-film transistor OLED displays for Apple as soon as the first half of 2021, according to a UBI Research note seen by The Elec. That's the same display technology that Samsung used in its Galaxy Note 20 devices.

UBI Research notes that Samsung is in the midst of converting its LTPS OLED display manufacturing systems over to LTPO. Although some production capacity is lost during the conversion process, the firm says that Samsung will be able to make 70,000 substrates per month.

According to the note, Apple will use the displays in its higher-end "iPhone 13" devices later on in 2021, likely be the so-called "iPhone 13 Pro" and "iPhone 13 Pro Max." Display panel orders for lower-end "iPhone 13" models could be filled by LG Display and BOE.

Compared to standard OLED displays, LTPO panels are more power efficient and will allow Apple to add 120Hz ProMotion technology to its upcoming iPhones.

The supply chain report lines up with rumors indicating that 120Hz ProMotion displays, which were first introduced on Apple's iPad Pro lineup, would be arriving on at least two iPhone models in 2021.

There were rumors suggesting that Apple would add 120Hz refresh rates would to the iPhone 12 or iPhone 12 Pro, but they didn't pan out. According to a display analyst, that's because LTPO technology would be necessary for power-efficient displays with 120Hz variable refresh rates.
