Device and method for addressing unintended offset voltage when driving display panel

Abstract:

A processing system comprises a plurality of output terminals connectable to data lines of a display panel and a plurality of output amplifiers configured to output a plurality of drive voltages, respectively. The drive voltages have the same polarity. The processing system further comprises first switch circuitry configured to connect a first output terminal of the plurality of output terminals to a selected one of the plurality of output amplifiers.
