Abstract:
1. An electro-luminescent device comprising an array of light-emitting elements, including a near white light-emitting element, wherein the near white light-emitting element includes an inorganic light-emitting layer of quantum dots, spaced between a pair of electrodes, and wherein the light-emitting layer produces a spectrum of light in response to a current supplied from the pair of electrodes, the spectrum of light having at least a bimodal distribution of wavelengths, and wherein each mode is formed from distinct spectral peaks and wherein each distinct spectral peak is separated from each additional distinct spectral peak forming each additional mode by an inter-modal minimum, the spectral radiant power of this inter-modal minimum being less than 5% of the maximum value within the spectral radiant power distribution.
