AI Technical Summary

Technical Problem

Existing display technologies struggle to achieve clear color reproduction and brightness, particularly in combining red, green, and blue light emissions, limiting the color gamut and overall display quality.

Method used

A light emitting apparatus is designed with a substrate and light emitting devices that emit specific luminous flux ratios in blue, green, and red wavelength regions, utilizing a color filter to shift color coordinates and enhance color reproduction, and incorporating wavelength converters to adjust and mix light emissions.

Benefits of technology

The apparatus achieves improved color brightness and reproduction, expanding the color gamut to meet higher standards like DCI-P3 and BT2020, ensuring vivid and clear color representation across various display devices.
