==BLUE COLOR CONVERTER FOR MICRO LED DEVICES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18586175 titled 'BLUE COLOR CONVERTER FOR MICRO LED DEVICES

The display described in the patent application includes a light emitting diode and a color conversion layer with a polymer matrix, a blue photoluminescent material, and components of a photoinitiator that initiated polymerization to form the polymer matrix. The blue photoluminescent material absorbs ultraviolet light in the range of 300 nm to 430 nm and emits blue light, with an emission peak between 420 nm to 480 nm and a narrow emission bandwidth.

* The display includes a color conversion layer with a unique blue photoluminescent material that efficiently converts ultraviolet light to blue light.
* The blue photoluminescent material has a narrow emission bandwidth, enhancing the color purity of the emitted light.
* The polymer matrix in the color conversion layer is formed through photoinitiated polymerization, ensuring uniform distribution of the blue photoluminescent material.
* The display is designed to have a high photoluminescence quantum yield, resulting in efficient light emission.

==Original Abstract Submitted==

A display includes a light emitting diode and a color conversion layer that includes a polymer matrix, a blue photoluminescent material, and a components of a photoinitiator that initiated polymerization to form the polymer matrix. The blue photoluminescent material is selected to absorb ultraviolet light with a maximum wavelength in a range of about 300 nm to about 430 nm and to emit blue light. The blue photoluminescent material also has an emission peak in a range of about 420 nm to about 480 nm. The full width at half maximum of the emission peak is less than 100 nm, and the photoluminescence quantum yield is in a range of 5% to 100%.
