Abstract:
A backlight (10) includes a front and back reflectors (12,14) forming a light recycling cavity (16) and one or more light source members (24a, 24b, 24c) disposed to emit light into the light recycling cavity. The front reflector (12) being partially reflective to provide an output illumination area. The front reflector (12) has a blue sloped transmission spectra, at normal incidence with a range among bin values from 15% to 100%.
