Abstract
An Amorphous IGZO (a-IGZO) TFTs pixel driving circuit and row driving circuit for AMOLED are proposed. The pixel driving circuit is composed of four a-IGZO TFTs and one capacitor (4T-1C), which effectively compensates the threshold-voltage-shift (ΔVth1V) of the drive TFT, and shift registers, NAND gates and inverters constitute the row driving circuit. To verify the effect of the proposed circuit, simulation using H-spice was performed, and results prove that the presented circuit can be applied to monochromatic 2-inches QVGA AMOLED.
