Apple Weighs HMO OLED Backplane With 30-50 cm²/Vs Target as LTPO Successor

Summary
LG Display is developing and validating High-Mobility Oxide TFTs on Gen-6 OLED lines as Apple studies the backplane as a lower-power, lower-cost replacement for LTPO in future devices.
Below-10 cm²/Vs mobility in current oxide TFTs has limited high-resolution, high-refresh OLED use; HMO aims for 30-50 cm²/Vs while avoiding LTPO steps such as laser crystallization and ion implantation.
sputtering is central to LG Display's approach because it can fit existing production infrastructure, but the company still must prove temperature control, large-area uniformity, reliability and acceptable yields before mass production.
Apple Watch panels could be the first commercial use as soon as next year, following Apple's pattern of testing new backplane technologies in wearables before expanding to more panel makers and eventually mobile devices.
Samsung Display is also advancing oxide OLED manufacturing, with 90% yields on advanced lines for future MacBooks, underscoring the broader race as Apple's commercialization timeline remains uncertain.
