A compensation circuit, a drive circuit, working methods for the compensation circuit and the drive circuit, and a display device comprising the drive circuit. The compensation circuit comprises a first compensation module (101) and a second compensation module (102). The first compensation module (101) generates a compensation voltage according to a variation quantity of a common electrode voltage. The second compensation module (102) superposes a gamma voltage input from a first input terminal of the second compensation module and the compensation voltage input from a second input terminal of the second compensation module, and outputs the superimposed gamma voltage. By transferring the compensation position from a common electrode voltage to a gamma voltage, and by means of a compensation voltage superimposed on a gamma voltage, the fluctuation of the common electrode voltage is effectively compensated and suppressed, thus avoiding the phenomena of an excessively high temperature of a display panel, a greenish display picture, and crosstalk noise. |
