摘要: | We fabricated and characterized the hydrogenate amorphous-silicon thin-film transistor (a-Si:H TFT) pixel-electrode circuit with the current-scaling function that can be used for active-matrix organic light-emitting displays (AM-OLEDs). As expected from previously reported simulation results, the fabricated pixel-electrode circuit showed an enhanced current-scaling performance for a high-resolution AM-OLED based on a-Si:H TFTs in comparison to other types of current-driven pixel circuits. It also showed a better electrical and thermal stability for different OLED current levels in comparison to the conventional current-driven pixel-electrode circuit. |
