Abstract
We propose a new integrated scan/emission driver circuit using 3-phase clock signals. The scan/emission part shares the clock lines, and no additional dummy stage is needed. The scan output is pulled up by both pull-down and -up TFTs to reduce the rising time and the size of the pull-up TFT. In addition, the emission output pulse width can be adjusted in 1 frame time. Therefore, the proposed circuit is applicable to reduce power consumption and improve image quality for high-resolution AMOLED displays. The simulation results verified the stable operation during the 1 frame time.
