In the first type of the column driver, two level shifters and two R-DACs are shared by four channels for die area saving. Two full resolution R-DACs and two less resolution R-DACs are used in four channels of the second column driver. Two experimental prototype 8-bit column drivers were implemented using 0.35-m CMOS technology to verify the proposed driving schemes. The maximum DNL and INL are 0.68 LSB and 0.68 LSB, respectively, for Type-I column driver, and are 0.81 LSB and 1.11 LSB, respectively, for Type-II column driver. Compared with a conventional fully R-DAC based TFT-LCD column driver, the proposed Type-I and Type-II column drivers have an area saving of 29.6% and 24.9%. In the rest of this thesis, a 10-bit TFT-LCD column driver IC with DAC-embedded op-amp is proposed. The 10-bit DACs are divided into positive 9-bit and negative 9-bit components for silicon die area saving. Each channel contains a 6-bit two-voltage selector and a 3-bit DAC-embedded op-amp in a cascaded manner. The 10-bit column driver prototype was realized in 0.18-m CMOS technology with the worst DNL/INL of 0.29/0.72 LSB. Compared with a conventional fully R-DAC based column driver, the proposed 10-bit column driver has an area saving of 45%. Chih-Wen Lu Yo-Sheng Lin 盧志文 林佑昇 2016 學位論文 ; thesis 65 en_US |
