摘要： A device is provided. The device comprises a first stacked light emitting device. The first stacked light emitting device comprises a first electrode, a second electrode, a first emissive unit comprising a first emissive layer, a second emissive unit comprising a second emissive layer and a first charge generation layer. The first emissive unit, the second emissive unit and the first charge generation layer are all disposed between the first electrode and the second electrode. The first emissive unit is disposed over the first electrode. The first charge generation layer is disposed over the first emissive unit. The second emissive unit is disposed over the first charge generation layer. The second electrode is disposed over the second emissive unit. The first emissive unit and the second emissive are independently addressable and may emit light independently of each other. The first emissive unit emits light having a first hue classified as red, green or blue and a first chromaticity having first CIE 1931 (x, y) colour space chromaticity coordinates of (xl, yl). The second emissive unit emits light having a second hue classified as red, green or blue and a second chromaticity having second CIE 1931 (x, y) colour space chromaticity coordinates of (x2, y2). The second hue is the same as the first hue. The second chromaticity is substantially different to the first chromaticity. The first emissive layer and the second emissive layer comprise organic light emitting material, quantum dot light emitting material and/or perovskite light emitting material.

摘要： A method of forming a halide perovskite nanocrystal array having a plurality of halide perovskite nanocrystals arranged in a pattern can include coating an array of pens with a first ink comprising at least one first perovskite precursor having the formula AX and at least one second perovskite precursor having the formula BX'2 dissolved in a solvent. A is a cation, B is a metal, and X and X' are each a halogen. The method further includes contacting a substrate with the coated pen array to thereby deposit the first ink indias a pattern of printed indicia on the substrate. The printed indicia form nanoreactors on the substrate and a halide perovskite nanocrystal nucleates and grows within each nanoreactor to form the halide perovskite nanocrystal array.
