  • Patent number: 10991290
    Abstract: Control methods of a channel setting module applied to a display panel are provided. The display panel has gate lines, source lines, and pixels. The pixels are arranged in matrix. The pixels disposed at the same row are electrically connected to the same gate line, and the pixels disposed at the same column are electrically connected to the same source line. The adoption of the channel setting module reduces the control signals required by the source lines. The channel setting module includes operational amplifiers and de-mux switches, and the control methods dynamically determine conduction states of the de-mux switches. The voltage outputs of the operational amplifiers are selectively outputted to the source lines, depending on conduction statuses of the de-mux switches. By applying the control methods, the interference between the source lines are reduced, and the instantaneous overshoots/undershoots of floating channels are depressed.
