ABSTRACT:
A source driving circuit for a display device may include a first latch configured to store first video data corresponding to a first horizontal line and a second latch configured to store second video data corresponding to a second horizontal line following the first horizontal line. The first and second latches may alternately store video data of different horizontal lines. The source driving circuit may further include a digital-to-analog converter (DAC) configured to convert the stored first and second video data into analog signals, a first sample-and-hold circuit configured to sample and store an output signal of the DAC, a second sample-and-hold circuit configured to sample and store an output signal of the first sample-and-hold circuit, and an output switch configured to provide an output signal of the second sample-and-hold circuits to the display panel.
