Abstract

The invention provides a display panel driving method and a display panel, and the method comprises the steps: obtaining a voltage data table stored in a storage module, searching a plurality of target data voltages in the voltage data table, and enabling a difference value between every two target data voltages to be smaller than or equal to a preset difference value; obtaining target pixel driving units corresponding to the plurality of target data voltages; and inputting the same data voltage to the plurality of target pixel driving units. In the pixel driving units of the data voltage with the preset input difference being small, the controller controls the input of the same data voltage, so that the display brightness of the pixel driving units of the data voltage with the preset input difference being small tends to be consistent. Therefore, the problem of bright and dark lines caused by wrong punching of data voltage when the display panel is in a high-refresh-rate working state is avoided, and the display brightness uniformity of the display panel in the high-refresh-rate working state is ensured.

Description

technical field [0001] The present application relates to the technical field of display circuits, in particular to a method for driving a display panel and the display panel. Background technique [0002] At present, most electronic devices have the function of displaying images, and liquid crystal display panels, as a main application device in electronic devices, are one of the important research directions in the field of display technology. In the liquid crystal display panel of the prior art, the problem of bright and dark lines displayed on the liquid crystal display panel caused by the data voltage stagger under the high refresh rate working state of the liquid crystal display panel, how to make the display brightness of the liquid crystal display panel more uniform has become a technology that needs to be solved question. Contents of the invention [0003] The present application discloses a display panel driving method and a display panel for making the display ...
