Abstract:
A backlight includes a front and back reflector forming a light recycling cavity and one or more light source members disposed to emit light into the light recycling cavity. The front reflector being partially reflective to provide an output illumination area. The front reflector has a blue sloped transmission spectra, at normal incidence with a range among bin values from 15% to 100%.
