Samsung plans to start making low-temperature polycrystalline oxide (LTPO) thin film transistor (TFT) OLED screens for Apple from the first half of 2021, according to a new note from research firm UBI Research shared by Elec.
Samsung plans to convert its current low-temperature polycrystalline silicon (LTPS) TFT OLED screen production to the new technology as Apple prepares to incorporate LTPO into its iPhone 13 screens.
LTPO monitors use less power than standard OLED monitors, and will allow Apple to implement 120Hz refresh rates rumored for the iPhone 13 series.
Elec says that Apple will use LTPO TFT OLED panels for higher-end iPhone models launched in 2021, which will be provided by Samsung. LG Display will offer standard LTPS TFT OLED panels for lower models.
This is in line with rumors suggesting that Apple’s advanced iPhone 13 Pro and Pro Max will have faster 120Hz refresh rates, enabling iPad Pro-like ProMotion technology.
There were rumors suggesting that 120Hz refresh rates could be introduced in the 2020 iPhone models, but display analyst Ross Young said Apple would not be able to introduce the feature until it was able to use LTPO monitors to allow a variable refresh rate, while maintaining battery life.
