Abstract: A driving system of a display panel and a driving method thereof are provided, in which the display panel includes a plurality of pixel units, and the driving system includes a timing controller and a voltage generator. The timing controller is used for detecting data values of the pixel units, and calculating difference values between the data values of every two pixel units, in which the calculated pixel units are in successive rows. The timing controller obtains an aggregation value of absolute values of the difference values, and then provides a related control signal to the voltage generator according to whether the aggregation value reaches a threshold value. The voltage generator provides a common voltage or provides a compensation voltage to a common electrode according to content of the control signal.

Abstract: A touch device and a touch sensing method thereof are provided. With driving lines and corresponding sensing lines are arranged alternately, the distance between the sensing lines is increased, so as to avoid touch quality being affected by the mutual interference caused by the sensing lines.

Abstract: A compensation circuit for a liquid crystal panel includes a plurality of source scan lines, a plurality of gate scan lines, a plurality of inverse gate scan lines, a plurality of pixel units, and a plurality of compensation units. Each source scan line is used for outputting a data voltage, each gate scan line is used for outputting a control signal, and each inverse gate scan line is used for outputting an inverse control signal. A pixel unit of the plurality of pixel units is charged/discharged to a voltage corresponding to a gray level according to a corresponding control signal and a corresponding data voltage, and a corresponding compensation unit provides a compensation voltage to compensate the voltage corresponding to the gray level according to an inverse control signal.
