OLED is short for organic light-emitting diodes, and there are a few key components that comprise how they work. An OLED display is sandwiched layers of semiconductors that emit light when receiving current.
LG has been one of the driving forces behind the further development of transparent OLEDs. This makes sense given their showing at CES 2023. LG has been the only manufacturer leveraging the tech and further refining it.
OLEDs are more energy-efficient than LED displays, and they don’t require external light sources to function like an LCD. This is in part thanks to their construction, which can create larger displays while also using fewer materials overall.
