It was first reported in November 2021 that LG had begun development of a new iPad 12.9" OLED display based on a two stack design with LTPO for 120Hz refresh rate for 2023 or 2024. Today The Elec is reporting on this development again.

The Elec reports that "LG Display is currently developing two models of OLED panels that it's aiming to supply to Apple’s iPads launching in the future. LG Display is developing 12.9-inch and 11-inch models, sources said. The company was the exclusive developer of the 12.9-inch model, they said.

Apple is planning to apply a two-stack tandem structure for the OLED panels it will use for future iPad models. The first iPads to sport OLED panels are expected to launch in 2024. Cupertino is also planning to apply low-temperature polycrystalline oxide (LTPO) thin-film transistors (TFT) on these panels which offers 120Hz variable refresh rate.

LG Display’s handling the development of two OLED panels aimed at iPads puts it at an advantage over Samsung Display in Apple’s display panel supply chain for iPads.

LG Display is likely handling more iPad OLED projects as it has more experience in manufacturing OLED panels with a two-stack tandem structure than Samsung Display.

LG Display had been using the two-stack tandem structure for the OLED panels it produces for automotive applications for years now.

Samsung Display just started the development of its own two-stack tandem structure tech and is developing materials sets called the T series for this."

Patently Apple covered this development in a report on March third titled "Samsung has begun development of a Two-Stack Tandem OLED Display first aimed for Apple's 2024 iPads and eventually Macs."

Both Samsung Display and LG Display, for the time being, are planning to use their existing Gen 6 (1500x1850mm) OLED lines to manufacture these OLED panels for upcoming iPads. For more read the full report by The Elec.
