We proposed the amorphous silicon thin-film transistor (a-Si:H TFT) pixel electrode circuit with current-scaling function that can be used for active-matrix organic light-emitting displays (AM-OLEDs). In contrast to the conventional current-mirror circuit, this circuit with cascaded storage capacitors can provide a high data-to-OLED current ratio without increasing the aSi:H TFT size. Moreover,...
