I nā makahiki i hala iho nei, me ka holomua wikiwiki o ka ʻenehana hōʻike, ua puka mai ka hōʻike OLED ma ke ʻano he manaʻo nui i ka hanauna hou o nā ʻenehana hōʻike, e huki ana i ka manaʻo nui mai nā kula a me nā ʻoihana. ʻO ka ʻenehana hōʻike OLED, ʻike ʻia hoʻi ʻo ka ʻenehana light-emitting diode organik, e hōʻike ana i kahi ʻano pale kūʻokoʻa a loaʻa iā ia nā mea maikaʻi he nui ma mua o ka ʻenehana LCD kuʻuna (liquid crystal display). Ke hoʻohana nui ʻia nei ia ma ka ʻāpana uila uila.
Hiki ke hoʻohālikelike ʻia ke ʻano o kahi pale OLED me kahi "hamburger light-emitting." Hoʻohālike kēlā me kēia ʻāpana OLED i kahi ʻano hana sandwich, me ka mea hoʻomālamalama kukui e hana ana ma ke ʻano he papa mea kanu i waena. ʻO ka mea kikoʻī, ʻo ka ʻōnaehana hōʻike OLED ka mea nui i kahi substrate (i hana pinepine ʻia me ka plastic transparent a i ʻole metala foil no ke kākoʻo), kahi anode, kahi papa organik (me kahi papa conductive a me kahi papa emissive), a me kahi cathode. Hoʻohana maʻamau ka papa conductive i nā polymers organik e like me ka polyaniline e lawe ai i nā lua, aʻo ka papa emissive e hoʻomaʻamaʻa i ka lawe electron a me ka hoʻokuʻu māmā.
Ma muli o ke ʻano kaʻa kaʻa, hiki ke hoʻokaʻawale ʻia nā pale OLED i nā ʻano active-matrix (AMOLED) a me passive-matrix (PMOLED). Hoʻolako ʻia nā OLED Active-matrix me nā transistors kiʻiʻoniʻoni lahilahi (TFTs), e hōʻemi pono i ka hoʻohana ʻana i ka mana, akā ʻoi aku ka maikaʻi o nā OLED passive-matrix i kekahi mau mea hana. ʻAʻole like me nā LCD, kahi e koi ai i kahi module backlight, ʻo ka pale OLED kahi mea hoʻokuʻu ponoʻī ʻaʻole pono i kahi kukui hope. ʻO kēia ka mea e maʻalahi ai kona hoʻolālā a lawe mai i nā pono he nui, e pili ana i nā kihi ʻike ākea, nā manawa pane wikiwiki, kahi kaʻa kaʻa kaʻa maʻalahi, ʻoi aku ka maʻalahi o ka hana kala, a me ka hiki ke hoʻokō i nā ʻano papa maʻalahi a hiki ke hoʻopaʻa ʻia.
Ma muli o nā loina hoʻolālā o ka māmā, lahilahi, pōkole, a me ka liʻiliʻi, kūpono ka ʻenehana OLED no nā panela liʻiliʻi a liʻiliʻi. Ua hoʻohana nui ʻia ia i nā mea pāʻani MP3, nā kelepona paʻa lima, a me nā ʻano mea uila uila like ʻole. ʻOiai aia kekahi mau huahana OLED i ka prototype a i ʻole ke kahua hoʻolaha hōʻikeʻike a ʻaʻole i komo i ka hoʻohana pono piha piha, ua loaʻa i kā lākou mau hiʻohiʻona hōʻike like ʻole i ka ʻike ākea i ka ʻoihana. I ka wā e hiki mai ana, ke hoʻomau nei ka ʻenehana, ua manaʻo ʻia ka hōʻike OLED e hoʻololi i nā pale LCD kuʻuna ma nā kula hou aʻe a lilo i mea hoʻonā hōʻike nui.
