Disclosed are a pixel circuit, a driving method thereof and a display device thereof. In the pixel circuit, when a driving module (02) provides a driving voltage to a light-emitting device (01), a sampling module (03) samples the driving voltage, a processing module (05) performs processing according to the driving voltage sampled by the sampling module as well as a correspondence relation between the pre-stored luminance of the light-emitting device (01) and the driving voltage as a function of service time, so as to obtain a compensation voltage corresponding to the driving voltage; a compensation module (04) inputs the compensation voltage determined by the processing module (05) into the corresponding light-emitting device (01). Thus, the function of differently compensating for the driving voltage of the light-emitting device according to different service time of the light-emitting device (01), the problem is solved that non-uniform display luminance of a display panel is caused by a decrease in the luminance of the light-emitting device (01) over the service time of the light-emitting device (01) when the same driving voltage is utilized to drive the light-emitting device (01), and the display luminance uniformity of the display panel is improved. |
