ABSTRACT:
A driver circuit, display system, and method includes a driver circuit that provides driving signals to drive a plurality of display pixel elements arranged in a plurality of rows and columns and coupled to associated row and column lines, respectively. The driver circuit includes a plurality of driver units coupled to associated ones of the plurality of column lines, and a plurality of switching components respectively coupled between outputs of ones of the driver units coupled to adjacent ones of the plurality of column lines. The driver units control associated ones of the switching components to electrically couple the adjacent outputs of the driver units to make the outputs the same or substantially the same when display data signals received for pixel elements coupled to the adjacent column lines are the same.
