C-axis aligned crystalline oxide semiconductor field-effect transistor (CAAC-OS FET) can be scaled down to a width and length of 60 nm. We have fabricated an organic light-emitting diode (OLED) display with more than 5000 ppi required in virtual reality (VR) displays by using CAAC-OS FETs as the backplane.
