Abstract
We propose and fabricate highly efficient current scaling AMOLED panel employing excimer laser annealed poly-Si TFTs, which successfully compensate the non-uniformity of IOLED due to the grain boundaries and residual image caused by a hysteresis phenomenon in poly-Si TFT. The proposed 2.4 inch panel employing a new current mirror pixel circuit successfully reduces a nonuniformity of the luminance from 41% to 9.1%, and eliminates residual image, compared with conventional 2-TFT pixel array. The proposed pixel circuit can also increase the data current by 57% and decrease the pixel charging time by 21%, compared with a traditional current mirror pixel
