Abstract:

To implement a compact and high-image-quality AMOLED mobile display, a previously proposed panel DAC concept was elaborated and improved. Three types of pixel structures for the panel DAC have been presented and discussed in terms of the yield, aperture ratio and timing margin. Also, the functional feasibility of the panel DAC has been verified by fabrication and measurement of low-temperature poly-Si TFT test circuits. The circuit area of the 8-bit DAC consisting of the 6-bit resistor-string-based DAC and the 2-bit cyclic panel DAC is increased by 26.7% compared with that of the 6-bit resistor-string-based DAC, whereas the conventional 8-bit resistor-string-based DAC quadruples the circuit area.
