Abstract
The present disclosure provides a method of compensating AMOLED pixel difference, including the steps of: fitting the driving voltage value and the driving current value of the reference pixel. Acquiring the threshold voltage, the coefficient and the power value corresponding to the reference pixel according to the fitting result. Acquiring the threshold change of the threshold voltage corresponding to the other pixel relative to the threshold voltage corresponding to the reference pixel and the coefficient ratio of the coefficient corresponding to the other pixel relative to the coefficient corresponding to the reference pixel. Compensating the other pixel difference according to the threshold change, the coefficient ratio and the power value. The disclosure makes the driving current under the same driving voltage be consistent, improves the uniformity of the light-emitting intensity of the AMOLED and enhances the display quality of the AMOLED display device.
