Abstract: The present application discloses a method for compensating data voltages in a display apparatus. The method for individually compensating a data voltage to be applied to one of the multiple pixel circuits in the display apparatus. The method includes obtaining a threshold voltage of the driving transistor in the one of the multiple pixel circuits. Additionally, the method includes applying a testing voltage to a gate electrode of the driving transistor for charging the sense line up to a first time period to determine a first monitoring voltage associated with the sense line. The testing voltage is set to be a sum of the threshold voltage and a first setting voltage. Moreover, the method includes compensating a data voltage to be applied to the one of the multiple pixel circuits based on the first monitoring voltage and the threshold voltage.
