An integrated scan-line driver, driving half aQQVGA flexible AMOLED display using amorphous-IGZO backplane technology on foil, has been designed andmeasured. A pulse-width modulation technique has been implemented, enabling to drive the OLEDs with a duty cycle up to almost 100%. The digital driving method also results in a 40% static power reduction of the display. Dynamic logic and bootstrapping techniques enabled the use of clock frequencies up to 300kHz in unipolar amorphous-IGZO technologies on foil.
