A current driver with 720 outputs for active-matrix organic LEDs uses a current-copier scheme to produce 64 gray levels with maximum 2% error from 10nA to 10uA on a 19.2 times 17.8mm2 die
A display driver IC based on a current-sink driving scheme has been developed for QVGA (240times320), low-temperature poly-silicon (LTPS) active matrix organic light-emitting diodes (AMOLEDs) displays. The current-mode driver IC consists of a source driver block and a controller block. It uses a sample-and-hold scheme in the source driver block. The source driver block has 720 channel outputs, an...
