Abstract
In some examples, an apparatus may include a backlight unit (BLU) including an electronic integrated circuit layer, a photonic integrated circuit layer, a color conversion module, and a display interface layer. In some examples, a BLU may include at least one laser or may be configured to receive laser light from at least one external laser source. Laser light may be transmitted towards a portion of the display interface layer using the photonic integrated circuit. Color conversion modules may be used to convert the laser light into one or more desired colors. Example apparatus may be used in head-mounted devices such as augmented reality and/or virtual reality devices. Other devices, methods, systems, and computer-readable media are also disclosed.
