Abstract:
1. A source driver on a semiconductor substrate for use with a display panel including source lines to be coupled to the source driver, gate lines to be coupled to a gate driver, and pixels arranged at crossings between the source lines and the gate lines, the source driver comprising: a plurality of output circuits to be coupled to the source lines of the display panel and including first output circuits and second output circuits outputting voltages corresponding to a plurality of gradations to be applied to respective source lines of the display panel; a timing controller coupled to the first and the second output circuits for controlling an output timing of the first and second output circuits; wherein, in a first output timing, the second output circuits output voltages after the first output circuits output voltages in a period for outputting voltages to respective source lines of the display panel; and in a second output timing, the first output circuits output voltages after the second output circuits output voltages in a period for outputting voltages to respective source lines of the display panel.
