Abstract:
A colour display module having spectrally corrected sources of light for use in a display panel having a plurality of like colour display modules, said display module including:sources of nominally red, green and blue colours, each source being subject to unwanted spectral variation; means associated with the nominally red source for activating the nominally green and blue sources to produce a spectrally corrected red source; means associated with the nominally green source for activating nominally red and blue sources to produce a spectrally corrected green source; and means associated with the nominally blue source for activating the nominally red and green sources to produce a spectrally corrected blue source; whereby the range of colours available to be displayed by the spectrally corrected red, green and blue sources substantially does not vary from one module to another notwithstanding the spectral variation of the nominally red, green and blue sources.
