Abstract
An assembly can include a first substrate, a second substrate, a non-light-emitting, variable transmission device deposited on the first substrate, and a transparent light-emitting device deposited on the second substrate, where the non-light-emitting, variable transmission device faces the transparent light-emitting device, and where the non-light emitting device alters an intensity of a wavelength prior to reaching the transparent light-emitting device.
