ʻO OLED (Organic Light-Emitting Diode) e pili ana i nā diode hoʻomālamalama organik, e hōʻike ana i kahi huahana hou i ke aupuni o nā hōʻike kelepona paʻalima. ʻAʻole like me ka ʻenehana LCD kuʻuna, ʻaʻole pono ka ʻenehana hōʻike OLED i kahi backlight. Akā, hoʻohana ia i nā uhi mea organik ultra-thin a me nā substrates aniani (a i ʻole nā substrates organik flexible). Ke hoʻopili ʻia kahi au uila, hoʻopuka kēia mau mea organik i ka mālamalama. Eia kekahi, hiki ke hoʻomālamalama a lahilahi nā pale OLED, hāʻawi i nā kihi nānā ākea, a hōʻemi nui i ka hoʻohana ʻana i ka mana. Ua hoʻohanohano ʻia ʻo OLED ʻo ia ka ʻenehana hōʻike hanauna ʻekolu. ʻAʻole wale nā hōʻike OLED i lahilahi, māmā, a ʻoi aku ka pono o ka ikehu akā ke kaena nei hoʻi i ka ʻōlinolino kiʻekiʻe, ka pono luminescence kiʻekiʻe, a me ka hiki ke hōʻike i ka ʻeleʻele maʻemaʻe. Eia kekahi, hiki ke piʻo ʻia, e like me ka ʻike ʻia ma nā TV curved-screen hou a me nā kelepona akamai. I kēia lā, ke holo wikiwiki nei nā mea hana honua nui e hoʻonui i nā hoʻopukapuka R&D i ka ʻenehana hōʻike OLED, e alakaʻi ana i kāna noi ākea i nā TV, nā kamepiula (monitors), nā kelepona akamai, nā papa, a me nā kahua ʻē aʻe. I Iulai 2022, ua hoʻolaha ʻo Apple i nā hoʻolālā e hoʻolauna i nā pale OLED i kāna laina iPad i nā makahiki e hiki mai ana. E hōʻike ʻia nā panela hōʻike OLED hou i nā hiʻohiʻona iPad o ka makahiki 2024, kahi hana e hoʻolilo ai i kēia mau panela i ʻoi aku ka lahilahi a me ka māmā.
ʻOkoʻa loa ke kumu hana o nā hōʻike OLED mai ko nā LCD. Hoʻokele nui ʻia e kahi kahua uila, hoʻokō nā OLED i ka hoʻokuʻu ʻana o ka mālamalama ma o ka hoʻokomo ʻana a me ka hui hou ʻana o nā mea lawe ukana i loko o ka semiconductor organik a me nā mea luminescent. I ka ʻōlelo maʻalahi, ua hana ʻia kahi pale OLED me nā miliona o nā "kukui kukui" liʻiliʻi.
ʻO kahi mea hana OLED he substrate, anode, hole injection layer (HIL), hole transport layer (HTL), electron blocking layer (EBL), emissive layer (EML), hole blocking layer (HBL), electron transport layer (ETL), electron injection layer (EIL), a me cathode. ʻO ke kaʻina hana hana o ka ʻenehana hōʻike OLED e koi ana i ka mākaukau loea kiʻekiʻe loa, i māhele nui ʻia i nā kaʻina hana mua a me hope. ʻO ke kaʻina hana mua e pili ana i ka photolithography a me nā ʻenehana evaporation, ʻoiai ke kaʻina hana hope e kālele ana i ka encapsulation a me nā ʻenehana ʻoki. ʻOiai ua akamai nui ʻia ka ʻenehana OLED holomua e Samsung a me LG, nui nā mea hana Kina e hoʻoikaika nei i kā lākou noiʻi ʻana i nā pale OLED, e hoʻonui ana i nā hoʻopukapuka kālā i nā hōʻike OLED. Ua hoʻohui mua ʻia nā huahana hōʻike OLED i kā lākou hāʻawi. ʻOiai he ʻokoʻa nui i hoʻohālikelike ʻia me nā pilikua honua, ua hiki kēia mau huahana i kahi pae hiki ke hoʻohana ʻia.
