초록
This paper has proposed a serial 8-bit DAC for column driver circuits of mobile displays using LTPS TFTs. The DAC circuit takes very small area by using parasitic capacitance of column lines as sampling and holding capacitors. Moreover, the proposed DAC does not need the analog buffer, because the DAC operation is performed on the column lines. For the data driver circuits of 2-inch qVGA OLED panel, the DAC area is
