Apple may adopt a new LTPO (low-temperature polycrystalline oxide) TFT backplane for future iPhones in order to reduce AMOLED power consumption, according to a IHS Markit report.The backplane is responsible for turning individual display pixels on and off and plays a significant role in determining resolution, refresh rates, and power consumption.
The company has applied for three LTPO related patents entitled, "Organic light-emitting diode displays with semiconducting-oxide and silicon thin-film transistors", "Displays with silicon and semiconducting oxide thin-film transistors", and "Methods of protecting semiconductor oxide channel in hybrid TFT process flow."
