Abstract
A display includes a backlight (). In addition, the display includes for each of at least one wavelength band, a plurality of layers placed above the backlight (). The plurality of layers includes an absorption layer (), a luminescent layer () and a reflective layer (). The absorption layer () is capable of absorbing light in a wavelength band while being substantially transparent to light in other wavelength bands. The luminescent layer () is capable, in response to light from the backlight (), of emitting light within the wavelength band. The reflective layer () is adapted to reflect light in the wavelength band while being substantially transparent to light in other wavelength bands.
