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.

Abstract: The invention provides a display panel driving apparatus and a driving method thereof. The display panel driving apparatus includes a source driver circuit and a timing controller circuit. The source driver circuit loads data to data lines of the display panel in load data periods. The timing controller circuit controls the source driver circuit for dynamically configuring a time length of one of the load data periods according to whether charge sharing occurs. When a charge sharing operation is not performed on at least two of the data lines in the load data period, the load data period has a first time length. When the charge sharing operation is performed on at least two of the data lines in the load data period, the load data period has a second time length longer than the first time length.

Abstract: An integrated circuit (IC), a display device and an anti-interference method thereof are provided. The IC includes an input pad, a source driving circuit and an anti-interference circuit. The input pad receives an input signal comprising image data from the external. The source driving circuit is coupled to the input pad to receive the input signal. The anti-interference circuit is coupled to the input pad to provide a variable capacitance. The anti-interference circuit adjusts the variable capacitance from a normal capacitance value to at least one anti-interference capacitance value when an interference event occurs to the input signal. The anti-interference circuit maintains the variable capacitance at the normal capacitance value when the interference event does not occur.
