Abstract

The invention discloses a display panel, a driving method thereof and a display device. Pre-charging control circuits in one-to-one correspondence with MUX signal input circuits are arranged; each pair of corresponding MUX signal input circuit and pre-charging control circuit are electrically connected with the same preset number of data lines; in a grid line scan period, when the MUX signal inputcircuit loads data voltage to the first data line, the pre-charging control circuit loads a pre-charging voltage to at least one second data line. When the MUX signal input circuit sequentially loadsthe data voltage to the second data line, the pixel charging time corresponding to the second data line can be additionally increased on the basis of the pixel charging time provided by the prior artdue to the fact that the second data line loads the pre-charging voltage in advance.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] At present, the data driving chip in the display outputs the pixel voltage to the pixel unit through the data line. Due to the large number of data lines in the display, correspondingly, the data driver chip needs more pins, so there are correspondingly more data transmission lines for transmitting data signals to each data line, which is not conducive to realizing a narrow frame of the display. In order to achieve a full screen, by reducing the number of data transmission lines, a MUX signal input circuit is set between the data driver chip and the data lines in the related art. At present, the commonly used solution is that the data driver chip can connect three sub-pixel units RGB through the MUX (which can be called 1:3MUX solution), and the data driver chip can connect six...
