| Title: |
Color Calibration System for a Video Display |
| Abstract: |
Large digital displays for entertainment, architectural and advertizing
displays have interconnected display panels with pluralities of light
emitting elements. To solve calibration problems, each of the display
panels stores measured luminance and chromaticity data for each of the
light emitting elements of the panel. The luminance data is independent
of the chromaticity data. A central controller can then perform
calibration procedures so that the light emitting elements are matched
across the entire display.
