    • An area illumination inorganic electro-luminescent device including a substrate; and an array of one or more commonly addressed, light-emitting elements. Each commonly-addressed, light-emitting element includes a first electrode layer formed over the substrate, one or more light-emitting layers formed over the first electrode layer and a second electrode layer formed over the light-emitting layer. The light-emitting layers include multiple core/shell quantum dot emitters formed in a common polycrystalline semiconductor matrix, and a number of different core/shell quantum dot emitters emit light with a spectral power distribution having a peak and a FWHM bandwidth, such that the peak wavelengths differ by an amount less than or equal to the average FWHM bandwidth of the different core/shell quantum dot emitters within the range of 460 to 670 nm.
    • 一种包括基板的区域照明无机电致发光器件; 以及一个或多个共同寻址的发光元件的阵列。 每个共同寻址的发光元件包括形成在衬底上的第一电极层,形成在第一电极层上的一个或多个发光层和形成在发光层上的第二电极层。 发光层包括形成在公共多晶半导体矩阵中的多个核/壳量子点发射器,并且许多不同的核/壳量子点发射器发射具有峰值和FWHM带宽的光谱功率分布的光,使得 峰值波长的差异小于或等于不同核/壳量子点发射器在460至670nm范围内的平均FWHM带宽的量。
