Meta Platforms, formerly Facebook, has scaled back its ambitions for AR glasses. The company's deal with British firm Plessey to develop augmented reality displays has not been successful, with development stalling and issues with brightness and manufacturing defects. Meta has decided to abandon Plessey's microLED tech in favor of an older display technology, liquid crystal on silicon (LCoS). This decision, among others, will reduce the competitive edge that the AR glasses have over existing AR headsets like Microsoft’s HoloLens.
