    Abstract: The embodiment of the present invention provides methods and apparatus for compensating data voltage and display devices and relates to a display field, which are capable of decreasing leakage currents of thin film transistors and improving or eliminating the vertical crosstalk phenomenon. The method for compensating data voltage, comprising the following steps of: determining whether a current frame is identical to a previous one frame; outputting a compensation voltage to compensate data voltage of the current frame if the current frame is identical to that previous one frame; and outputting information about the frame according to the compensated data voltage.

    Abstract: A method for driving a display apparatus includes: in a first refresh period which corresponds to a first refresh rate and includes a first effective phase and first ineffective phase(s), outputting a first image frame signal to a display panel of the display apparatus in the first effective phase, and outputting a first ineffective data signal to the display panel in a first ineffective phase; and in a second refresh period which corresponds to a second refresh rate and includes a second effective phase and second ineffective phase(s), outputting a second image frame signal to the display panel in the second effective phase, and outputting a second ineffective data signal to the display panel in a second ineffective phase. The first refresh rate is different from the second refresh rate, and the first ineffective data signal and the second ineffective data signal have different magnitudes in voltage.

    Abstract: A method of driving a scan circuit includes providing N number of first clock signals time-sequentially to (k*N) number of stages of the scan circuit, respectively. The (k*N) number of stages includes M number of groups. A respective group of the M number of groups includes one or more stages of the scan circuit. A respective first clock signal of the N number of first clock signals includes a first level component and a second level component. With respect to N number of data enabling signals, a difference between a starting point of a first level component of an n-th first clock signal and a starting point of an n-th data enabling signal of the N number of data enabling signals is equal to tm1. Values of tm1 for first clock signals provided to different groups of the M number of groups are different.
