Abstract

A large sector of display market comprises portable devices including cell phones, personal organizers, PDAs, portable electronic games, etc. Important design considerations for displays employed in these applications are power consumption and cost. Hydrogenated Amorphous silicon (a-Si:H) active matrix organic light emitting diode (AMOLED) displays are promising technology for these applications. However, the a-Si:H AMOLED backplane suffers from the temporal instability. Although, several stable driving schemes have been proposed, they suffer from high implementation cost due to extra driving circuitry and high power consumption due to additional operating cycles. This paper presents a new driving scheme that provides a stable AMOLED display despite the aging effects in the a-Si:H thin film transistors and OLED, without increasing the driving complexity
