Abstract

The present invention features procedures for correcting discoloration and brightness variations due to liquid crystal cell gap variations or other optical, electro-optical, ambient light, electronic, mechanical, and materials anomalies arising in tiled, flat-panel displays. The purpose of these corrections is to achieve a visually seamless appearance. Absolute, relative and/or smoothing corrections are implemented by performing pixel data video processing with correction data acquired from memory. Techniques for determining and applying these corrections are described.
