Claim 10:
11. A display device, comprising:
a panel including a plurality of pixels at separate, respective intersections of a plurality of gate lines and a plurality of source lines;
a gate driver configured to drive one gate line of the plurality of gate lines in response to a horizontal synchronization signal and a gate control signal;
a source driver configured to drive the plurality of source lines according to data; and
a timing controller configured to receive a clock signal, the data, a vertical synchronization signal, and the horizontal synchronization signal, and to control the gate driver and the source driver,
wherein the source driver includes a plurality of data drivers corresponding to the plurality of source lines,
wherein each of the data drivers is configured to
latch first data at a first line time period;
latch second data at a second line time period;
latch third data at a third line time period;
convert the first data to a first voltage in a latency operation;
amplify the first voltage within 2-line time in a charging operation;
convert the second data to a second voltage;
amplify the second voltage in a second output amplifier within 2-line time;
output the amplified first voltage to one source line of the plurality of source lines within 1-line time overlapping the converting the first data to the first voltage; and
output the amplified second voltage to the one source line within 1-line time, and

wherein each of the data drivers includes
a first driving cell connected to the one source line and configured to perform one of the latency operation and the charging operation; and single source line in parallel, such that
a second driving cell connected to the one source line in parallel with the first driving cell and configured to perform one of the latency operation and the charging operation,

wherein the second driving cell is configured to perform the charging operation when the first driving cell performs the latency operation based on a first switching operation;
wherein the second driving cell is configured to perform the latency operation when the first driving cell performs the charging operation based on a second switching operation; and
wherein the first switching operation and the second switching operation operate complementarily to each other.
