Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light sources such as light-emitting diodes. The light-emitting diodes may be mounted on a printed circuit. A reflector may be formed on the printed circuit to help reflect light from the light- emitting diodes upwards through the pixels. The reflector may include two white ink layers. Multifunctional layers and other optical films may be incorporated into the backlight. These layers may include diffusers, microlens array layers, thin-film interference filters, phosphor layers, light-collimating layers, and reflective polarizers.
