CONTROL METHOD, DEVICE AND ELECTRONIC SYSTEM UTILIZING THE SAME

Abstract

A control method for a display panel including a plurality of pixel units arranged in a matrix is disclosed. A plurality of video signals are received. A sequence of the video signals and a preset arrangement are compared. When the sequence of the video signals differs from the preset arrangement, polarities are provided to the video signals by a first inversion method for generating a plurality of first data signals. When the sequence of the video signals corresponds to the preset arrangement, polarities are provided to the video signals by a second inversion method for generating a plurality of second data signals. The second data signals are output to the pixel units.
