Apple Watch users have some good news. Sources in the supply chain say a new display technology in the upcoming Series 10 will improve battery life significantly.

In a report from the Korean tech publication The Elec, the Series 10 will use a thin-film transistor (TFT) display made from low-temperature polycrystalline oxide (LTPO). There are a few parts of the Apple Watch’s OLED screen that use LTPO, while other parts use less efficient technology.

Apple Watch Series 10 is expected to use LTPO more extensively. With LTPS transistors being replaced by oxide transistors, display-pixel-connected transistors become oxide transistors. LTPO OLEDs minimize leakage current by using oxides, and this method signifies a wider application of oxides in displays. This change will likely benefit oxide technology manufacturers. Most users are concerned about battery life, so this translates to a longer battery life.

There is, however, some concern that newer features of the Series 10 watch may overshadow efficiency gains. Still, Apple Watch fans are excited about the prospect of a longer-lasting Apple Watch.
