摘要： 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.

摘要： The invention discloses an LCD driving circuit, a data-driven chip, a liquid crystal panel, and a liquid crystal display. The LCD driving circuit comprises a data-driven chip with a plurality of output ends, and a plurality of data lines connected to the output ends of the data-driven chip respectively. Output resistors are arranged between the output ends of the data-driven chip and the data lines respectively; equivalent resistances of the data lines are different; and the equivalent resistance of each of the data lines is equal to the sum of the output resistances corresponding to the data line. The invention adopts the output resistors to substitute serpentine windings. Because the width occupied by the output resistances is less than the width occupied by the serpentine windings, a winding space in a glass substrate can be saved to realize a narrow frame design. In addition, because a frame per unit width can accommodate more data lines, thus the cost can be decreased.
