Abstract

A 10-bit source driver using low temperature poly-silicon(LTPS) TFTs is developed. To reduce the DAC area, the DAC structure including two 5-bit resistor-string DACs and analog buffer, which has analog adder is proposed. The source driver is fabricated using LTPS process and its one channel area is $3,200{\mu}m\;{\times}\;260{\mu}m$. The simulated INL and DNL of output voltages are less than 3 LSB and 1 LSB, respectively.
