Abstract
An integrated scan-line driver, driving half a QQVGA
flexible AMOLED display using amorphous-IGZO backplane
technology on foil, has been designed and measured. A pulse-width
modulation technique has been im plemented, 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
