Abstract: A pixel voltage compensation method, a pixel voltage compensator device and a display device are provided. The compensation method includes: determining a capacitance between at least one data line adjacent to a target pixel electrode and the target pixel electrode; detecting a voltage difference between a driving voltage of the data line and a driving voltage of the target pixel electrode in a period from a start of present charging of the target pixel electrode to a start of next charging; calculating a variation of the driving voltage of the target pixel electrode caused by the capacitance and the voltage difference; and compensating for the driving voltage of the target pixel electrode according to the variation. This compensation method can suppress the phenomenon of voltage cross-talk, and thus can improve the display effect of the display device.
