ʻO ke ʻano o nā hōʻike OLED

ʻO OLED (Organic Light-Emitting Diode) e pili ana i nā diodes māmā māmā, 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 kukui hope. Akā, hoʻohana ʻo ia i nā mea hoʻoheheʻe kūlohelohe ultra-thin a me nā substrate aniani (a i ʻole nā ​​​​substrats organik maʻalahi). Ke hoʻohana ʻia ke au uila, hoʻopuka kēia mau mea organik i ka mālamalama. Eia kekahi, hiki ke hoʻomāmā a lahilahi nā pale OLED, hāʻawi i nā kihi ʻike ākea, a hoʻemi nui i ka hoʻohana ʻana i ka mana. Hoʻohanohano ʻia ʻo OLED e like me ke kolu o ka ʻenehana hōʻike. ʻAʻole ʻoi aku ka lahilahi o nā hōʻike OLED, ʻoi aku ka māmā, a ʻoi aku ka ikaika o ka ikehu akā ke haʻaheo nei nō hoʻi i ka ʻōlinolino kiʻekiʻe, ʻoi aku ka maikaʻi o ka luminescence, a me ka hiki ke hōʻike i ka ʻeleʻele maʻemaʻe. Hoʻohui ʻia, hiki iā lākou ke curved, e like me ka ʻike ʻia i nā TV curved-screen hou a me nā smartphones. I kēia lā, ke holo nei nā mea hana nui o ka honua e hoʻonui i ka hoʻopukapuka R&D i ka ʻenehana hōʻike OLED, e alakaʻi ana i kāna noi ākea ākea i nā TV, nā kamepiula (nā mākaʻikaʻi), nā kelepona, 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 lineup iPad i nā makahiki e hiki mai ana. ʻO nā hiʻohiʻona iPad 2024 e hiki mai ana e hōʻike i nā panela hōʻike OLED hou i hoʻolālā ʻia, kahi kaʻina hana e hoʻolilo i kēia mau paneli i ʻoi aku ka lahilahi a me ka māmā.

ʻOkoʻa ke kumu hana o nā hōʻike OLED mai ka LCD. Hoʻokele mua ʻia e kahi kahua uila, loaʻa nā OLED i ka hoʻokuʻu māmā ʻana ma o ka injection a me ka hui hou ʻana o nā mea lawe uku i nā mea semiconductor organik a me nā mea luminescent. ʻO ka waiho wale ʻana, aia kahi pale OLED me nā miliona o nā "puʻi kukui."

Aia ka mea OLED me kahi 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 ka cathode. ʻO ke kaʻina hana o ka ʻenehana hōʻike OLED e koi i ka mākaukau ʻenehana kiʻekiʻe, i māhele ākea 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 hope hope e pili ana i ka encapsulation a me nā ʻenehana ʻoki. ʻOiai ʻo ka ʻenehana OLED ka mea i haku nui ʻia 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 ma nā hōʻike OLED. Ua hoʻohui ʻia nā huahana hōʻike OLED i kā lākou mau makana. ʻOiai kahi ākea koʻikoʻi i hoʻohālikelike ʻia me nā pilikua honua, ua hiki kēia mau huahana i kahi pae hoʻohana.
