Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic device comprising: a pixel region including a first thin film transistor, the first thin film transistor being formed over a substrate; a source signal line side driver operationally connected to the pixel region, said source signal line side driver comprising a second thin film transistor wherein the second thin film transistor is formed over the substrate; a gamma correction control circuit operationally connected to the source signal lin…
