Abstract :
A novel data driver for passive matrix organic lightemitting devices (OLEDs) with high gray scale images was designed. The proposed circuit consisted of a main current bias circuit as well as sample & hold circuits in each channel of the data driver to compensate a current offset. These results indicate that a designed data driver by using a current offset compensation technique holds promise for potential applications in passive matrix OLED displays with high gray scale images.
