Abstract

The invention relates to a driving method and a driving device of a display panel. The display panel comprises a source driving circuit, a gate driving circuit, a plurality of gate signal lines electrically connected to the gate driving circuit, and the data lines electrically connected to the source driving circuit. The driving method comprises the following steps of: generating the first delay signals with time from short to long respectively corresponding to the data lines from a far to near connection distance with the source driving circuit. Then, generating the second delay signals withtime from short to long respectively corresponding to the data lines from a near to far horizontal distance with the gate driving circuit. Finally, the source driving circuit outputs driving signals to each data line according to the first delay signal and the second delay signal corresponding to each data line, so that each pixel point driven by different data lines on the same gate line has thesame charging time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method and a driving device of a display panel. Background technique [0002] When the existing liquid crystal panel drives pixels at different positions, the connection distance between each pixel and the driver is not equal, that is, the transmission impedance is inconsistent, resulting in a charging delay difference (RC delay). When the same timing driving signal is used, the actual charging time of each pixel is not the same, which will lead to uneven panel display or color shift. For large-size panels, the problem of uneven display will be more obvious due to the greater transmission impedance of the signal lines. [0003] Therefore, it is necessary to provide a driving method and a driving device of a display panel to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a driving method and a d...
