The present invention relates to the field of display technology, and provides a display panel drive circuit, a drive method, and a display panel. The display panel includes a plurality of data lines, and the display panel drive circuit further includes: a pre-punched line, a power supply circuit and a plurality of switch units . The pre-punched wire is connected to a plurality of the data lines; the power supply circuit is connected to the pre-punched wire for providing a pre-charged voltage to the pre-punched wire; a plurality of switch units are arranged in a one-to-one correspondence with the plurality of the data lines , the first end of the switch unit is coupled to the pre-charge line, and the second end is coupled to the data line, for in the pre-charge stage, in response to a control signal, connect a plurality of the data lines and connect the The precharge voltage on the precharge line is transmitted to the data line. The display panel driving circuit provided by the present disclosure can reduce the power consumption of the display panel source driving circuit.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel driving circuit and driving method, and a display panel. Background technique [0002] A display panel generally includes a plurality of sub-pixel units distributed in an array, and each sub-pixel unit can emit light of a specific color, thereby realizing the display of the display panel. [0003] In the related art, a display panel generally includes a plurality of data lines extending in a column direction, a plurality of scan lines extending in a row direction, a source driving circuit and a gate driving circuit. Each data line is connected with a plurality of sub-pixel units, the source driving circuit can transmit data signals to the plurality of data lines, and the data signal can be used to drive the sub-pixel units, and the gate driving circuit can pass the scan lines to the sub-pixel units row by row. The pixel unit sends scan signals row b...
