Display system, control device, and control method

In a display system, a source drive circuit outputs a source signal. Multiple switching elements are respectively connected between multiple source lines and the source drive circuit, and each switching element outputs a source signal output from the source drive circuit to a source line in an ON state and stops the output of the source signal to the source line in an OFF state. A switching circuit supplies multiple pulse signals to the multiple switching elements. A CPU determines pulse widths of the multiple pulse signals. The pulse widths of the multiple pulse signals are determined such that each of the pulse widths of the multiple pulse signals is longer than or equal to a charging time of a pixel electrode and such that the sum of the pulse widths of the multiple pulse signals is shorter than or equal to a horizontal synchronization period.
