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.

Abstract: A method for driving a display panel and a display panel thereof. Method comprises: A driving circuit regulates electrical levels of the driving signals in a driving cycle transmitting to a first/second/third charging control unit corresponding to a first/second/third color sub-pixel unit respectively. Therefore, the first color sub-pixel unit is charged via a first thin-film-transistor of the first charging control unit by charging data, the second color sub-pixel unit is charged via a first thin-film-transistor and a second thin-film-transistor of the second charging control unit by said charging data, and the third color sub-pixel unit is charged via a first thin-film-transistor of the third charging control unit by charging data.
