Abstract: The present invention provides a compensation circuit for display images and a method for determining compensation region for display images. The method calculates a first compensation boundary and a second compensation boundary corresponding to the locations of panel cut regions. The region between the first compensation boundary and the second compensation boundary is an image compensation region for compensating the pixels therein. Thereby, according to the compensation circuit and method of the present invention, the image compensation region can be determined corresponding to the locations of the panel cut regions. By adjusting the compensation boundaries, the image compensation region can be modified.
