Abstract

Conventional current drivers are incapable of programming high-resolution hydrogenated amorphous silicon (a-Si:H) active matrix organic light-emitting diode (AMOLED) displays within the frame time requirement. This paper presents a new fast settling current driver. While the settling time of the conventional drivers is of the order of milliseconds (ms), the new current driver presented here can settle under 40 µs, thus providing for high-resolution current-programmed a-Si:H AMOLED displays such as QVGA (320 240), SVGA (800 600), and XGA (1024 768).
