Abstract | Design considerations are presented for a-Si:H based AMOLED display backplanes, including 2-TFT voltage-programmed and 4-TFT threshold-voltage-shift-resistant current-programmed circuits. The RC equivalent models of voltage-programmed and current-programmed pixels are derived, based on which array simulations are performed. Array size scalability and optimal driving requirements for a-Si:H AMOLED pixels are also presented. The TFTs used were fabricated in-house and the array under consideration is a (320 times;240) QVGA operating at 60 frames/s |
