Abstract:
A semiconductor display device correcting system includes a control circuit for carrying out gamma correction of a picture signal supplied from the outside and a nonvolatile memory for storing data for gamma correction. The data for gamma correction is prepared for each semiconductor display device, so that excellent gradation display can be made.
