Abstract
Large digital displays for entertainment, architectural and advertising 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.
Claims6
An apparatus for calibrating a display comprising a plurality of light emitting elements comprising:
- a plurality of receptors, each corresponding to at least one of the light emitting elements;
- a spectrometer;
- and
- a fiber optic splice configured to connect the plurality of receptors to the spectrometer.
