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.
