Patent attributes
A driver circuit includes an operational amplifier OPC1 which drives a data line by a rail-to-rail operation or a non-rail-to-rail operation based on a grayscale voltage corresponding to one of first to Pth (P is an integer of four or more) grayscale values, and an operational amplifier control section OPCC1 which causes the operational amplifier OPC1 to perform the rail-to-rail operation or the non-rail-to-rail operation based on grayscale data. When the sth (1≦s≦P, s is an integer) grayscale value corresponding to the grayscale data is in a range of the qth (1<q<P, q is an integer) to rth (q<r<P, r is an integer) grayscale values, the operational amplifier OPC1 drives the data line by the non-rail-to-rail operation based on the grayscale voltage corresponding to the sth grayscale value, and, when the sth grayscale value is not in the range of the qth to rth grayscale values, the operational amplifier OPC1 drives the data line by the rail-to-rail operation based on the grayscale voltage corresponding to the sth grayscale value.
