Source driving apparatus, method of driving the same, display device having the same and method of driving the same

摘要

A source driving apparatus includes a latch, an additional-data generator, an output controller and a buffer. The latch latches a normal-data signal received and outputs the latched normal-data signal. The additional-data generator generates an additional-data signal having a low value on the gray-scale and outputs the additional-data signal. The output controller controls the additional-data generator to output the generated additional-data signal during an invalid data interval of a predetermined frame. The buffer buffers the normal-data signal and the additional-data signal and outputs the normal-data signal and the additional-data signal. Therefore, instantaneous afterimage phenomenon may be eliminated by changing the structure of the source driver.
