OUTPUT CIRCUIT, AND DATA DRIVER AND DISPLAY DEVICE USING THE SAME

摘要

An output circuit includes a connection switch and an operation unit. The connection switch includes first to third terminals for receiving first to third voltages, respectively, selects and outputs the first voltage or the second voltage or the third voltage to each of the first to seventh intermediate terminals, including selection of the same voltage for a plurality of the intermediate terminals. The connection switch switches assignment of the first to third voltages to the first to seventh intermediate terminals responsive to a connection switching signal. The operation unit receives the voltages assigned to the first to seventh intermediate terminals and outputs to an output terminal a voltage obtained by performing a predetermined operation on the voltages supplied to the first to seventh intermediate terminals.
