An Area-Efficient 10-Bit Source-Driver IC With LSB-Stacked LV-to-HV-Amplify DAC

Abstract

This article presents an ultra-compact 10-bit source driver IC (SD-IC) developed for mobile organic light-emitting diode (OLED) displays. The proposed LSB-stacked low-voltage (LV)-to-high-voltage (HV)-amplify digital-to-analog converter (DAC) allows the area-consuming 8-bit voltage selector to be implemented with compact LV transistors (LV-MOS) as well as obtains an additional DAC resolution of 2-bit by dissipating little die area. By virtue of the LV-MOS voltage selector, level- shifters (L/S)
