Method and apparatus for controlling display panel, display module and electronic device

An apparatus for controlling a display panel, wherein the display panel is provided with a target display region comprising a plurality of pixel circuits arranged in an array;

• the apparatus comprising a control circuit and a source drive circuit, wherein
• the control circuit is configured to control polarities of data signals transmitted by the source drive circuit to the pixel circuits in partial columns in the target display region to be inverted when a (KN−1)th frame is displayed, and control polarities of data signals transmitted by the source drive circuit to the pixel circuits in other columns than the partial columns in the target display region to be inverted when a KNth frame is displayed,
• wherein K is an ordinal number of a control period, and K is an integer greater than or equal to 1;
• and N is a number of frames corresponding to one control period, and N is an integer greater than 1.
