Summary:The present invention provides a gamma correction method applied in multi-channel driver of display and its device. The method starts with converting an m-bit input signal corresponding to a gamma curve simulated by m bits into an n-bit input signal for being inputted together with another n-bit input signal into a driving element. The driving element compares the two signals to output a PWM driving signal to a specific data channel. Because the two input signals of the driving element are of n bits, the driver can be an n-bit digital driving element with less number of bits, so as to surely decrease large layout area and thus reduce the manufacturing cost.
