2027 Apple Watch Could Adopt Next-Generation OLED Display Tech

Apple is evaluating a new OLED display backplane technology that could make future Apple Watch models more power efficient, according to a new report from Korean publication The Elec. LG Display is said to be developing high-mobility oxide, or HMO, thin-film transistor technology for its sixth-generation small and medium-sized OLED production lines. The technology is reportedly being considered by Apple as a next-generation successor to low-temperature polycrystalline oxide, or LTPO – the TFT backplane technology currently used to enable iPhone and Apple Watch features like always-on displays and variable refresh rates. HMO is designed to improve on conventional oxide TFT displays by increasing electron mobility (i.e., how easily electrons move through the transistor material when an electric field is applied). Mobility is important for driving OLED panels while keeping power consumption low, and The Elec says current mass-produced oxide TFTs typically offer mobility below 10
