Application: Light-emitting element, display device and light-emitting element manufacturing method (Patent ID: US20230403874A1)
The patent filed by Sharp Corp. describes a light-emitting element that includes a first light-emitting layer with quantum dots and spacer particles. The quantum dots have a core and shell with an outer layer containing a metal chalcogenide complex or compound. The spacer particles have a core and shell with an outer layer containing a metal chalcogenide complex or compound. The element can be used in display devices, with different elements emitting light at different wavelengths based on the core material and size of the spacer particles.
The light-emitting element in the patent consists of quantum dots with specific core materials and shell compositions, along with spacer particles that also contain metal chalcogenide complexes or compounds. The elements can emit light at different wavelengths based on the core material and size of the spacer particles, making them suitable for use in display devices. The patent also includes claims related to the bandgap of the core materials, the size of the spacer particles, and the volume ratio of spacer particles to the light-emitting layer. Additionally, the patent describes a display device with multiple light-emitting elements, each emitting light at different wavelengths based on the core material and spacer particle size, allowing for versatile and efficient display technology.
