Abstract: An active matrix organic light emitting diode (OLED) display device includes an array of pixels, each pixel including an OLED, a driving transistor (DT) coupled to drive current through the OLED, a storage capacitor, and a scanning transistor (ST) coupled to control charge on the storage capacitor corresponding to a data voltage for said pixel. The display device also includes a timing controller configured to control the ST of each pixel to update the charge stored on the storage capacitor of each pixel at a frame rate including at least one frequency within a range of 1-10 Hertz (Hz).
