Abstract: A driving circuit for a display panel is disclosed. The driving circuit includes at least a driving signal line connected to a display driving signal transmission unit delivering display driving signal produced by the display driving signal transmission unit to sub-pixels of the display panel through the driving signal line; and a number of data signal lines connected to a display data provision unit delivering display data signal produced by the display data provision unit to the sub-pixels. For each subset of the sub-pixels that are of a same component color, at least two data signal lines, starting from different points of time, deliver display data signal to the subset of sub-pixels that are of the same component color. The driving circuit effectively resolves glitches to input signal resulted from heavy transient load to the input signal.
