Control method for display panel

A control method for a display panel,

• the display panel comprising:
• a plurality of gate lines, a plurality of data lines arranged to intersect with the plurality of gate lines in an insulative manner, and a plurality of sub-pixels arranged in an array, wherein sub-pixels with different colors from each other connected to same gate line constitute a repeat unit;
• and
• a demultiplexer, wherein N data lines for charging the sub-pixels with different colors from each other are connected to one signal input terminal through the demultiplexer, wherein N is an integer greater than 1, and
• the control method comprising:
• providing a scanning signal to a gate line in each row to perform progressive scan;
• and
• turning on the demultiplexer to charge sub-pixels connected to the demultiplexer when the scanning signal is inputted, wherein timing sequence control signals corresponding to the data lines have a same turn-on duration, and sub-pixels with a same color have a same charging time period in a preset period, and a sequence of turn-on levels occurring in the timing sequence control signals corresponding to the data lines is changed at least once in the preset period, wherein
• the preset period is display time of N frames of image;
• ranks corresponding to time instants when turn-on levels occurs in the timing sequence control signals corresponding to the same data line in the N frames of image are different from each other;
• and
• in each preset period, a sequence of turn-on levels occurring in the timing sequence control signals corresponding to the N data lines in one of any two frames of image is different from a sequence of turn-on levels occurring in the timing sequence control signals corresponding to the N data lines in the other of the any two frames of image.
