A control method for a display panel is provided, the display panel includes multiple gate lines, multiple data lines arranged to intersect with the gate lines in an insulative manner, multiple sub-pixels arranged in an array and a demultiplexer. The N data lines for charging the sub-pixels with different colors are connected to one signal input terminal through the demultiplexer, N is an integer greater than 1. The control method includes charging the sub-pixels connected to the demultiplexer in a direct charging manner, and the sub-pixels with the same color have the same charging time period in a preset period.
