摘要： A display driving circuit includes a buffer section, an N-dot switch circuit, a charge sharing switch circuit, and a sharing voltage level control switch circuit. The buffer section buffers a plurality of pixel driving signals outputted from a plurality of DACs. The N-dot switch circuit selects paths of the plurality of pixel driving signals outputted from the buffer section in response to a first path selecting signal or a second path selecting signal that is determined depending upon a dot inversion method, and switches the paths to a plurality of output terminals. The charge sharing switch circuit shares charges among the plurality of output terminals in response to a charge sharing control signal. The sharing voltage level control switch circuit controls charge sharing between the plurality of output terminals and a voltage level upon charge sharing, in response to a sharing voltage level control signal.
