According to Taiwanese media Digitimes, which is usually well aware of the gossip of Asian manufacturing lines, Apple's first device using Micro LED display technology will be an Apple Watch Ultra in 2024, at worst 2025.
Apple has been developing Micro LED technology since 2014
The information reiterates that Apple has been developing its own Micro LED displays since the company bought the LuxVue company in 2014. In addition, other rumors earlier this year already pointed to the arrival of an Apple Watch Micro LED for 2024. The high cost and production difficulties of this technology explain why Apple will start with small screens. The Micro LED process will then be available on iPhone, iPad and MacBook.
