"CAAC stands for C-Axis Aligned Crystal. In this material's structure, the crystals are aligned in the c-axis direction. Because CAAC itself is crystalline instead of amorphous, it has much higher reliability. Until now, with oxide semiconductors, reliability was generally thought to be a problem, but using this material solves that problem.
"One point about CAAC is that it enables flexible displays that can be freely designed. Another point is, CAAC enables very high TFT drive performance, because its mobility is high. So, with this material, high resolution can be achieved even in big displays.
SEL demonstrated a 3.4-inch 960x540 pixel display with a resolution of 326 ppi, and a 5.4-inch 960x1280 pixel display with a 302 ppi resolution. The prototype wrist device with a 3.4-inch OLED display and a bendable lithium ion battery can be put on and taken off over 10,000 times.
"A display that can be bent into a diameter of 4 mm is probably unparalleled worldwide. In particular, this is the only technology that can display a picture on bent edges."
