WHAT’S HOLD­ING OLEDS BACK?

HWM (Singapore) - - Learn -

While there are many ad­van­tages of OLEDs such as thin­ner dis­plays, deeper blacks and more ef­fi­cient en­ergy us­age, there are still some dis­ad­van­tages. The tech­nol­ogy still needs to over­come some hur­dles be­fore it can be­come the norm for tele­vi­sions.

The pri­mary prob­lem hold­ing back OLEDs at present is the short life­span on blue OLEDs. A blue OLED at half bright­ness has a life­span of 14,000 hours when it is used in a flat panel dis­play com­pared to a 25,000 to 40,000 hours life­span for the blue com­po­nent of LCD, LED and Plasma dis­plays. Since green OLEDs and red OLEDs do no de­grade at the same rate, OLED dis­plays have a ten­dency to lose their color bal­ance as time pro­gresses.

Ad­di­tion­ally, OLEDs are more sus­cep­ti­ble to wa­ter dam­age than other tech­nolo­gies. They also have a ten­dency to per­form poorly un­der strong and bright am­bi­ent light due to the com­po­nents used.
