Abstract
Official abstract text for this publication.
A color conversion panel includes a first color conversion layer, a second color conversion layer, and a light wavelength conversion layer. The first color conversion layer includes a first semiconductor nanocrystal set for providing red light. The second color conversion layer neighbors the first color conversion layer and includes a second semiconductor nanocrystal set for providing first green light. The light wavelength conversion layer neighbors the second light conversion layer, may provide blue light, and includes a third semiconductor nanocrystal set for providing second green light.
First claim
Opening claim text (preview).
What is claimed is: 1. A color conversion panel comprising: a first color conversion layer including a first particle set configured to convert first blue light to emit red light; a second color conversion layer neighboring the first color conversion layer and including a second particle set configured to convert second blue light to emit first green light; and a light wavelength conversion layer neighboring the second color conversion layer and configured to emit second green light and transmit third blue light, wherein the light wavelength conversion layer includes fewer elements configured to provide green light than the second color conversion layer.
