Patent ID: 7852304

Claim:
A driver circuit for providing driving signals to drive a plurality of display pixel elements arranged in a plurality of rows and columns in a display system, the rows and columns of display pixel elements being coupled to associated ones of the row and column lines, respectively, the driver circuit comprising: a plurality of driver units coupled to associated ones of the plurality of column lines, each of the driver units being configured to receive display data signals for the associated column line and an adjacent one of the column lines, and to provide a drive signal on a driver unit output to the display pixel elements coupled to the associated column line; and a plurality of switching components respectively coupled between the outputs of ones of the driver units coupled to adjacent ones of the plurality of column lines, and configured to electrically couple the adjacent outputs in response to a control signal from an associated one of the driver units when the display data signals for the adjacent column lines are the same; wherein each of the plurality of driver units includes: a column line driver circuit configured to supply the drive signal corresponding to the display data signals to the associated column line for the associated pixel elements coupled thereto; and a data compare circuit configured to receive the display data signals for the associated column line and the adjacent one of the column lines, and to provide a signal to a one of the switching components coupled between the outputs of the associated driver unit and a one of the driver units associated with the adjacent column line to electrically couple the adjacent outputs.
