A 512ch 10b Source-Driver IC with Current-Mode Auto-Zeroing Scheme Achieving 1.4mV DVO and 600ns 1-Horizontal Time for Mobile OLED Displays

This paper presents a 10b source-driver IC (SD-IC) for ultra-fast, uniform-luminance mobile OLEO displays. A current-mode auto-zeroing (CM-AZ) scheme transparently cancels output-buffer offset-lowering DVO with zero timing penalty-while simultaneously suppressing AC-coupling errors in the LSB-stacked DAC. Fabricated in 180nm CMOS with an 11.37µm channel pitch, the 512ch SD-IC achieves a 600ns 1-H time and a 1.4mV DVO, successfully demonstrated on an LED display panel.

Abstract

This paper presents a 10b source-driver IC (SD-IC) for ultra-fast, uniform-luminance mobile OLEO displays. A current-mode auto-zeroing (CM-AZ) scheme transparently cancels output-buffer offset-lowering DVO with zero timing penalty-while simultaneously suppressing AC-coupling errors in the LSB-stacked DAC. Fabricated in 180nm CMOS with an 11.37µm channel pitch, the 512ch SD-IC achieves a 600ns 1-H time and a 1.4mV DVO, successfully demonstrated on an LED display panel.
