MicroLEDs used to fix and replace an old OLED lighting installation in Taipei
Many years ago, The W Hotel in Taipei installed an OLED installation called You Fade to Light, designed by rAndom International creative studio and powered by Philips' OLED lighting panels. This beautiful piece consists of 2,000 modules, each lighting up as a response to people moving in front of it.
After several years these OLED panels started to fail (and fade, which is rather ironic given the installation's name), and now the hotel replaced the OLED panels with microLED-powered panels. It is said that the microLEDs achieved the same level of uniformity and light output of the OLEDs, maybe even surpassing them.
