Abstract

The device has an analysis unit for analyzing images output from an LCD screen (LCD1), to determine photometric and colorimetric parameters of the images. Another analysis unit analysis images output from another LCD screen (LCD2), to determine another photometric and colorimetric parameters. A weighting unit applies a weighting law e.g. linear law, to the parameters to determine an average photometric and colorimetric parameter. A linear display (AL) includes an active display area having luminance and colorimetry as representative of average photometric and colorimetric parameter. An independent claim is also included for a display system.
