Abstract

This study proposes an area-efficient fully resistor digital-to-analog converter (R-DAC) based thin-film transistor liquid crystal display (TFT-LCD) column driver in which one positive polarity DAC and one negative polarity DAC are shared by four channels. An experimental prototype 8-bit column driver was implemented using 0.35-m CMOS technology to verify the proposed driving scheme. The settling time is within 5 s and the maximum DNL and INL are 0.68 LSB and 0.67 LSB, respectively. The average area per channel is 0.016 mm2. Compared with a conventional fully R-DAC based TFT-LCD column driver, the proposed driving scheme has an area saving of 29.6%.
