Abstract
A driving method of a liquid crystal display (LCD) panel comprises a scan driving process and a data driving process. In the scan driving process, overlapping time regions are formed simultaneously between a positive edge and a negative edge of the scan lines when a drive of a last row of a scan line is switched to drive of a next row of the scan line. In the data driving process, when a time of data signal corresponding to the last row of the scan line overlaps a time of the overlapping time regions, the data signal corresponding to the next row of the scan line are outputted.

A driving method of a liquid crystal display (LCD) panel, comprising:
- a scan driving process, where in the scan driving process, simultaneously forming overlapping time regions between a positive edge and a negative edge of the scan lines when drive of a last row of a scan line is switched to drive of a next row of the scan line;
- and
- outputting a data signal corresponding to the next row of the scan line when a time of data signal corresponding to the last row of the scan line overlaps a time of the overlapping time regions.
A driving circuit of a liquid crystal display (LCD) panel, comprising:
- scan lines, a scan driving chip coupled to the scan lines, data lines, a data driving chip coupled to the data lines, and a data monitoring module;
- the data driving chip forming simultaneously overlapping time regions between a positive edge and a negative edge of the scan lines when the data driving chip switches drive of a last row of a scan line to drive of a next row of the scan line;
- wherein the data monitoring module outputs a data signal corresponding to the next row of the scan line when a time of the data signal corresponding to the last row of the scan line overlaps a time of the overlapping time regions.
