We developed a vertical oxide semiconductor transistor (VFET) having a small footprint and a high on-state current, and fabricated a 513-ppi OLED display with an RGB stripe arrangement and an internal compensation pixel circuit. VFET is fabricated through a simpler process than LTPO FET and enables low-power and high-resolution displays.
