Abstract
The present disclosure relates to a display device, including at least one or more light sources disposed for each pixel and a light conversion layer disposed on the light source to convert a wavelength of light generated from the light source, wherein the light conversion layer includes a perovskite matrix and quantum dots.
Claims21
A display device, comprising:
- at least one or more light sources disposed for each pixel;
- and
- a light conversion layer disposed on a light source to convert a wavelength of light from the light source,
- wherein the light conversion layer comprises a perovskite matrix and quantum dots, and
- wherein the perovskite matrix comprises a perovskite including an organic ammonium ion serving as a spacer,
- wherein the perovskite matrix is represented by Chemical Formula 1:
- An−1B2MnX3n+1, [Chemical Formula 1]
- where A is the organic ammonium ion, B is a cation, M is a metal cation, X is a halogen anion and n is an integer of 2 or more.
5 more elements
A display device, comprising:
- a substrate;
- a plurality of sub-pixels on the substrate, the plurality of sub-pixels including at least a first sub-pixel including a first emission device, a second sub-pixel including a second emission device, and a third sub-pixel including a third emission device;
- a first light conversion layer disposed on the first emission device, wherein the first light conversion layer comprises a perovskite matrix and one or more first quantum dots, the one or more first quantum dots configured to absorb light emitted from the first emission device and emit light of a first wavelength;
- and
- a second light conversion layer disposed on the second emission device, wherein the second light conversion layer comprises a perovskite matrix and one or more second quantum dots, the one or more second quantum dots configured to absorb light emitted from the second emission device and emit light of a second wavelength,
- wherein the perovskite matrix comprises a perovskite including an organic ammonium ion serving as a spacer,
- wherein the perovskite matrix is represented by Chemical Formula 1:
- An−1B2MnX3n+1, [Chemical Formula 1]
- where A is the organic ammonium ion, B is a cation, M is a metal cation, X is a halogen anion and n is an integer of 2 or more.
