Apple Supply Chain Partners Developing OLED Displays With Low-Power LTPO Technology: Digitimes

As Apple gears up to release it next-gen iPhone lineup, a new report from Digitimes (via MacRumors) says that the Cupertino company’s supply chain partners are developing OLED displays using LTPO (low-temperature polycrystalline oxide) technology.

A paywalled preview of the Digitimes report explains:

iPhone OLED screens may adopt LTPO backplanes in 2021, say sources
Apple has yet to introduce its 5G iPhones for 2020, but its supply chain is already developing OLED screens using LTPO backplane technology for next year’s premium iPhone models, according industry sources.

LTPO technology will provide more power or energy-efficient backplanes for the upcoming devices and is responsible for handling individual pixels on the panel. Since the entire display is not lighting up and only the required pixels light up, it serves to save power and ultimately enhances battery life.

“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),” OLED-info explains. “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.”

Apart from being more power-efficient, LTPO technology can also pave way for more features like an always-on display, ProMotion, and much more. Previously, Jon Prosser and Max Weinbach have said that ProMotion might be part of the 2020 series iPhones.
