“However, a new kind of backplane TFT is rising on the horizon which the Apple iPhone may adopt in the long term- the so-called LTPO, or low-temperature polycrystalline oxide,” Hsieh writes. “In fact, Apple has applied for three important patents on LTPO.”
“Backplane technology is important because it covers the components in thin-film transistors that drive the main display. The backplane is what is responsible for turning individual pixels on and off, and so plays a significant role in determining a display screen’s resolution, refresh rates, and power consumption,” Hsieh writes. “Apple in the long term may want to have more control over components of the flexible OLED.”
There are several reasons for Apple to introduce LTPO:
• To be more closely involved in flexible OLED component cost and technology
• To reduce power consumption of Apple products
• To achieve high electron mobility for higher resolution of its displays
• To better manage its display supply chain and that of its partner-display manufacturers
Hsieh writes, “IHS Markit believes Apple may ask display suppliers to start deploying LTPO first on the Apple Watch, and then gradually introduce it in the iPhone display over the long term.”

MacDailyNews Take: Surely Samsung competitors who covet Apple’s display business (LG Display, for example) are working on diligently overcoming challenges to high-volume LTPO production right now.
