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 second core of the spacer particle contains a material with a larger bandgap than the first core, and various materials can be included in the cores such as CdS, ZnO, GaAs, and Si. The spacer particle size, emission wavelengths, and composition of the shells are also specified in the claims.

Furthermore, the patent also covers a display device incorporating multiple light-emitting elements, each with quantum dots and spacer particles. The elements can have different emission wavelengths and spacer particle sizes, allowing for a range of colors to be displayed. The second light-emitting element in the display device includes quantum dots with shorter emission wavelengths and a lower amount of spacer particles compared to the first element. The composition of the shells for the quantum dots in the second element is also specified in the claims. Overall, the patent aims to improve the efficiency and color range of light-emitting elements and display devices through the use of specific quantum dot and spacer particle configurations.
