META'S NEW 2MM LASER DISPLAY COULD ENABLE TRUE AR GLASSES

Summary from the TLDR newsletter

Meta researchers have found a new use for photonic integrated circuits (PICs), chips that can receive, modulate, and direct light. Their PICs can receive RGB light from laser light sources integrated into a panel, process it, then shine light onto a liquid crystal on a silicon panel for final display. The overall complex is just two millimeters thick and has a dramatically better color gamut over similar displays. These PICs are manufactured using a CMOS-compatible process, which means they should be affordable to create at scale.
