Abstract

The application discloses a display panel and a driving method thereof. The display panel comprises a plurality of pixel units, a plurality of data lines, a comparison unit, a brightness detection unit and a driving unit. A mixed color picture is displayed in the pixel unit group, the comparison unit compares the gray-scale values of all the pixel units; the brightness detection unit detects the brightness of the display unit. The gray-scale values of all the pixel units are the same and are greater than a gray-scale preset value; and when the display brightness of the first pixel unit electrically connected with a first data line is greater than the display brightness of the second pixel unit electrically connected with a second data line, the driving unit reduces the driving voltage of the first data line to a preset voltage value, so that the display brightness of the first pixel unit is the same as the display brightness of the second pixel unit. And the horizontal cross grain canbe effectively improved without increasing the output value of the driving voltage.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a driving method thereof. Background technique [0002] As the size of LCD panels becomes larger and larger, refresh rates of 120Hz and higher have become standard configurations for high-end display panels. The Flip pixel architecture is used in the panel. [0003] The Flip pixel structure means that the pixel units with the same polarity in two adjacent rows of pixel units are connected to the same data line. In order to improve the horizontal stripes that exist during color mixing in the Flip pixel structure, the industry will adopt line OD technology (LineOver Driver, Overdrive technology) to drive the pixel unit, that is, when the pixel unit is driven, by increasing the output value of the pixel driving voltage, the pixel unit is driven with a driving voltage greater than the value of the target voltage of the pixel unit. [0004] However, th...
