|20080246388||INFRARED DISPLAY WITH LUMINESCENT QUANTUM DOTS - A display device that includes an underlying excitation source, a converting layer, and an optical filter layer. The underlying excitation source emits light in a spatial pattern that may or may not be altered in time and has a short wavelength capable of being at least partially absorbed by the overlying converting layer. The converting layer can be a contiguous film or pixels of quantum dots that can be dispersed in a matrix material. This converting layer is capable of absorbing at least a portion of the wavelength(s) of the light from the underlying excitation source and emitting light at one or more different wavelengths. The optical filter layer prevents the residual light from the excitation source that was not absorbed by the converting layer from being emitted by the display device.||10-09-2008|
