In the world ofOLEDpanels , there are two main types of OLED material : fluorescent and phosphorescent . Historically , fluorescent fixture OLED has been the easiest to knead with , but it ’s far less effective than phosphorescent organic light-emitting diode , which is why , for years , the video display industry has been endeavor to develop the technology needed to make a 100 % phosphorescent OLED ( PHOLED ) panel . And while we ’re still not quite there , LG Display read it has crossed a major milestone in that journeying , byverifying the commercialisation of panels that use blue phosphorescent PHOLED material — the first time all three primary OLED coloring ( red , fleeceable , and blue ) have been produced from PHOLED fabric in a format that is workable for aggregated production .
In possibility , a 100 % PHOLED board would demonstrate 99 % efficiency , with almost all of the energy waste being convince into luminosity , with scarcely any heat . LG Display ’s PHOLED technology , which is base on ahybrid two - push-down storage Tandem OLEDstructure , does n’t quite get to this peak of carrying into action . The ship’s company expend fluorescent fixture blue OLED in the lower flock , with blue PHOLED contribute to the top stack .
The companionship is only claiming a 15 % free energy deliverance over panel that habituate fluorescent fixture blue OLED , but it ’s still tangible validation that PHOLED may one day meet its loft expectations .
LG Display
LG Display is set to demonstrate its raw racy PHOLED panels at SID Display Week 2025 in San Jose , California on May 11 . For now , the fresh panel are intended for small and medium - sized applications like smartphones and pad . For portable , electric battery - driven devices , any energy savings — especially in the display , which be given to consume most of the powerfulness — is a welcome alteration .
The race to commercialize blue PHOLED began in 2023 , when Universal Display Corporation ( UDC ) announced it had successfully created a blue phosphorescent OLED textile that could get together the demands of commercial mass production . At the clip , no company had formally sign on to process with UDC on the process , but it was wide believe that both Samsung Display and LG Display were considering it .
In 2024 , LG Display harbinger that it would start out working with UDC on the task — that was eight calendar month ago . In the short terminus , the destination will be to test these fresh panels bear the promised benefit . long - term , it will be interesting to see if LG Display can develop a bicycle-built-for-two gore that use 100 % PHOLED material , and if it can scale the technology up to the sizing of today ’s OLED television receiver .
At the size of a TV , vigor efficiency is less authoritative that heat reduction . An OLED panel that runs cooler can bunk brighter , and can theoretically maintain that brightness for longer , without aging the OLED fabric . 100 % PHOLED display could prove just as able in brilliantly lit rooms as their QLED counterpart , one of the few expanse where QLED technology continues to enjoy an advantage over organic light-emitting diode .
