The invention relates to a pixel circuit compensation method. The pixel circuit compensation method includes the steps: acquiring the threshold voltage of a driving transistor in each sub-pixel in a display panel; determining whether the threshold-voltages of all the sub-pixels in the same line or the same row are abnormal voltages, and/or, determining whether the threshold voltages are in the preset voltage range; if the threshold voltages are the same, determining that the threshold-voltages of all the sub-pixels in the same line or the same row are abnormal voltages, and/or, determining that the threshold voltages are abnormal voltages if the threshold voltages are not in the preset voltage range; and adjusting a compensation signal input to the first sub-pixel corresponding to the abnormal voltage. The pixel circuit compensation method and apparatus can determine the abnormal voltage in the threshold voltage of the driving transistor in each sub-pixel according to the characteristics of the abnormal voltages, and can adjust the compensation signal input to the first sub-pixel according to the first sub-pixel corresponding to the abnormal voltage instead of inputting the presetcompensation signal to the first pixel so as to guarantee that the input compensation signal can accurately compensate the first sub-pixel.
