Apple has yet to complete its transition from LCD to OLED, but will at some point move beyond this to microLED screens. Key supplier Foxconn has announced that it expects to begin mass production of the advanced display tech late next year.Foxconn made the announcement as it revealed a partnership with Porotech for microLED to be used in future AR headsets Apples move toward micro-LEDApple is so still to complete its transition to its third display technology, OLED:Originally, it used LCD with conventional backlightingThen it moved on to LCD with mini-LED backlightingThe Apple Watch, iPhone, and latest iPads currently use OLEDWith MacBooks to follow, likely in 2026Apple is already looking ahead to an even more advanced display tech, however, known as micro-LED. This offers even brighter displays with greater color accuracy, longevity, and power efficiency, and without the burn-in weakness of OLED.The company was expected to begin this move with a microLED Apple Watch, but later cancelled (or, likely, postponed) this plan as the tech wasnt sufficiently advanced.Foxconn preps for mass production of microLEDKey Apple partner Foxconn has announced that it expects to begin mass production of its first microLED screens late next year.
