Abstract:
1. 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, wherein the data monitoring module comprises a detection module, a control module, and a timing module that presets a delay time; when the detection module detects that the drive of the last row of the scan line is switched to the drive of the next row of the scan line by the scan driving chip, the timing module starts to time; when the time reaches the delay time, the control module outputs a data activating signal; the data driving chip is controlled to drive the corresponding data lines; the sum of the delay time and duration time of the data activating signal is not less than time of the overlapping time regions.
