Abstract

A class-B output buffer with threshold voltage (VTH) compensation for the data driver circuit fabricated on liquid crystal display (LCD) panel in low temperature polysilicon (LTPS) technology is proposed. This output buffer can be operated at 50-kHz operation frequency with a 2-to-8 V output swing for extended graphic array (XGA) application. By employing the design technique of threshold voltage compensation, the offset voltage (V OS) of the class-B output buffer under 2-to-8 V input signal can be controlled within ± 100 mV for a high resolution and quality applications in LCD panel.
