Abstract: A dual source driver includes first and second gamma voltage generators configured to generate first and second gamma voltages, respectively, first and second latches configured to latch first and second data, respectively, a first driving cell configured to receive the first gamma voltage and the first data, and to transmit a first voltage corresponding to the first data and the first gamma voltage to a panel load based on a first switching operation, and a second driving cell configured to receive the second gamma voltage and the second data, and to transmit a second voltage corresponding to the second data and the second gamma voltage to the panel load based on a second switching operation. The first switching operation and the second switching operation may operate complementarily to each other.
