Claim 14:
15. A mobile device, comprising:
an application processor that is configured to control overall operations of the mobile device;
a display panel including a plurality of pixels at separate, respective intersections of a plurality of gate lines and a plurality of source lines;
a display driving circuit configured to receive source data from the application processor and to display the source data in the display panel; and
a power supply circuit configured to manage power of the application processor, the display panel, and the display driving circuit,
wherein the display driving circuit includes a plurality of data drivers corresponding to the plurality of source lines, the plurality of data drivers each including a first driving cell and a second driving cell,
wherein each of the plurality of 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 the first driving cell and the second driving cell are connected in parallel to the one source line such that
the first driving cell outputs the amplified first voltage to the one source line within 1-line time in the charging operation concurrently with the second driving cell performing the latency operation based on a first switching operation, and
the second driving cell outputs the amplified second voltage to the one source line within 1-line time in the charging operation concurrently with the first driving cell performing the latency operation based on a second switching operation,
wherein the first switching operation and the second switching operation operate complementarily to each other.
