ʻO kekahi o nā hiʻohiʻona nui o ka ʻenehana ʻo ia ka mea i lawe mai iā mākou i nā hōʻike OLED. Inā ʻoe i ka mākeke no kahi hōʻike hou a makemake ʻoe e loaʻa nā hiʻohiʻona āu e manaʻo ai, a laila pono ʻoe e ʻimi pono i nā hōʻike OLED. I kēia wā wikiwiki, pono e ʻike i nā pono o nā hōʻike OLED.
He aha ka OLED?
ʻO OLED ka pōkole o "diode māmā māmā". ʻO kekahi inoa ʻo "organic electroluminescent diode". Hoʻopuka pololei ʻo ia i ka mālamalama ma o ka uila, ʻaʻole like me ke ala maʻamau o ka hoʻokuʻu ʻana i ke kukui ma ka hoʻomehana ʻana i ka filament me ka uila. Hoʻokumu ʻia nā hōʻike OLED me nā ʻāpana aniani o ka aniani, ka plastik a me nā molekala kūlohelohe kūikawā e pane ana i ka hoʻoiho uila a hoʻohua i ka wela haʻahaʻa. ʻO ka hoʻopā ʻana i ka hōʻike OLED ʻaneʻane ʻaʻole mahana, kahi e mālama ai i ka nui o ka ikehu, ʻo ia kahi hoʻomaikaʻi nui ma mua o nā hōʻike CRT hoʻohana kiʻekiʻe o ka wā i hala.
Ka Moolelo o OLED
Hiki ke ʻike ʻia ka ʻike ʻana o ka ʻenehana OLED hou i ka makahiki 1987. I kēlā manawa, ʻelua mau ʻepekema mai Donman Kodak, ʻo Steven Van Slyke a me Ching Tang, ua ʻike i kekahi mau mea ola e hiki ke hoʻokuʻu i ka māmā ma ka haʻahaʻa haʻahaʻa. I ka hoʻomaka ʻana o ka makahiki 1960, ʻo ka loaʻa ʻana o ka fluorescence lohi i paʻa i ke ala no ka hānau ʻana o OLED. ʻOiai pono nā mea kūlohelohe mua i ka volta kiʻekiʻe e hoʻokuʻu i ka mālamalama, ua kūleʻa nā ʻepekema Kodak i ka loaʻa ʻana o ka fluorescence ma ka haʻahaʻa haʻahaʻa.
Ua hoʻomohala mua kēia poʻe ʻepekema i nā OLED me kahi kikoʻī melemele-ʻōmaʻomaʻo, a laila he kikoʻī ʻalani-ʻulaʻula, a hope loa i lanakila i ke kānāwai awāwa ikehu e hoʻokō pono ai i ka hoʻokuʻu ʻana i ka diode ʻulaʻula. Ma hope mai, i ka hoʻomaikaʻi ʻana o ka ʻenehana, ua ʻike ʻia nā hōʻike OLED hou e like me AMOLED (active matrix organic light-emitting diode).
Nā mea nui o kahi hōʻike OLED
ʻO ka puʻuwai o kahi hōʻike OLED ʻo ka OLED emitter. He ʻāpana organik ia e hoʻopuka i ka mālamalama ke hoʻohana ʻia ka uila. Aia ka papa hana maʻamau ma waena o ka anode a me ka cathode. Loaʻa i nā polokalamu OLED hou nā papa e hoʻomaikaʻi i ka lōʻihi a me ka pono, akā mau ka hana maʻamau. Hoʻokumu ʻia nā panela OLED me kahi papa mua, kahi papa hope, nā electrodes, kahi papa encapsulation, a me kahi substrate. He mea maʻalahi kēia ʻōnaehana i ka wai a me ka oxygen, no laila paʻakikī loa ka papa encapsulation.
Pāpaʻa
ʻO ke kumu o nā hōʻike OLED he aniani a i ʻole ka substrate plastik, kahi mea akaka e hāʻawi ai i kahi ʻili paʻa no nā mea ʻē aʻe.
Nā Papa Organic
Hoʻokomo ʻia nā ʻāpana he nui o nā mea organik ma kahi substrate, me:
Papa hoʻopuka: Loaʻa i nā molekala organik e hoʻopuka i ka mālamalama ma lalo o ka hoʻoulu uila.
Papa lawe puka:Lawe i nā uku maikaʻi (puka) i ka papa hoʻokuʻu.
Papa lawe uila: Lawe i nā uku ʻino (electrons) i ka papa hoʻokuʻu.
Layer Conductive Alohilohi
Aia kēia papa ma nā ʻaoʻao ʻelua o ka papa organik a hana ma ke ʻano he electrode māmā, e ʻae ana i ke kahe e kahe i loko a i waho o ka papa organik.
Papa Hoʻopāpā
No ka pale ʻana i ka papa organik palupalu mai ka makū a me ka oxygen, hoʻohana pinepine ʻia kahi papa encapsulation ma luna, aia kahi mea pale e pale ai i nā mea kūlohelohe mai ka hoʻopili ʻana i ka papa organik.
ʻO nā pono a me nā pōʻino o ka hōʻike OLED
Pono
- ʻO ka hoʻolālā ʻuala ʻoi loa:ʻOi aku ka lahilahi o nā hōʻike OLED ma mua o ka LCD a me nā hōʻike LED.
- ʻoluʻolu:Hiki ke palaki ka substrate o OLED, e maʻalahi.
ʻōlinolino kiʻekiʻe: ʻOi aku ka mālamalama o ka papa kukui a ʻaʻole pono ke kākoʻo aniani.
Haʻahaʻa hoʻohana ikehu:ʻAʻole koi ʻia ke kukui hope, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka mana, a ua kūpono ia no nā mea uila.
Maʻalahi e hana:Hiki ke hana ʻia i nā ʻano nui a kākoʻo i nā mea plastic, kahi maʻalahi e hoʻonui.
Nā pōʻino
pilikia kala:He pōkole ke ola o nā mea ola polū.
ʻO ke kumukūʻai hana kiʻekiʻe:Hiki ke hoʻopōʻino i ka ʻōnaehana OLED.
Nā polokalamu hōʻike OLED
Ua holomua ka ʻenehana OLED i nā noi like ʻole:
Nā TV nui:ʻIke ʻia nā TV OLED no kā lākou kiʻi maikaʻi loa.
Hōʻailona Kikohoʻe:Hoʻohana ʻia e huki i ka manaʻo ma nā hale kūʻai kūʻai, nā hale ʻaina, nā mokulele, a me nā mea hou aku.
Pā wikiō:He pā wikiō nui i haku ʻia me nā hōʻike OLED he nui e hana i kahi ʻike immersive.
Hōʻike poʻo-up:hoʻohana ʻia i nā mahiole kaʻa kaʻa no ka hāʻawi ʻana i ka ʻike e pono ai me ke keʻakeʻa ʻole i ka ʻike.
OLED alohilohi:no nā hōʻike kaʻa a me nā aniani ʻoiaʻiʻo i hoʻonui ʻia.
I ka manawa hea e koho ai i kahi hōʻike OLED no nā noi kālepa?
Hāʻawi nā hōʻike OLED i ke ʻano hiʻohiʻona maikaʻi loa no nā noi pāʻoihana kahi mea nui o nā hiʻohiʻona kupaianaha. Eia kekahi mau manaʻo nui:
• maʻiʻo hoʻonā kiʻekiʻe:He koho maikaʻi loa nā hōʻike OLED inā pono e hōʻike ʻia nā kiʻi kiʻekiʻe, wikiō, a i ʻole nā kiʻi.
•Nā kihi ʻike ākea:Hāʻawi nā hōʻike OLED i nā kihi nānā like ʻole, e hōʻoia ana e hōʻike pololei ʻia ka ʻike ke nānā ʻia mai nā kihi like ʻole.
•Hoʻolālā lahilahi a māmā:ʻOi aku ka lahilahi a ʻoi aku ka māmā o nā hōʻike OLED ma mua o nā hōʻike LCD kuʻuna, e kūpono ana ia no nā noi kahi i kaupalena ʻia a i ʻole kahi hoʻolālā nani.
•Haʻahaʻa mana hoʻohana:ʻOi aku ka ikaika o nā hōʻike OLED ma mua o nā hōʻike LCD, e hōʻemi ana i nā kumukūʻai hana a me ka hopena o ke kaiapuni.
Inā makemake kāu noi pāʻoihana i ka maikaʻi o ke kiʻi, nā kihi ākea ākea, a me ka hoʻolālā nani, ʻo ka hōʻike OLED ke koho maikaʻi loa.
ʻO ka ʻokoʻa ma waena o OLED Vs LED/QLED Hōʻike
Hoʻokumu ʻia nā hōʻike LED kuʻuna ma luna o ka ʻenehana LCD, kahi hale i hoʻāʻo ʻia i ka manawa. Aia nā pale LCD i kahi mānoanoa lahilahi o nā transistors e hana ana me nā mea aniani liʻiliʻi. ʻO kēia kaʻina hana e pili ana i ka hoʻoponopono ʻana i nā pixels ʻeleʻele a ʻālohilohi, akā ʻo ka hoʻokuʻu ʻana o ka mālamalama maoli mai ka mālama ʻana i nā LED. ʻO ke ala maikaʻi loa e hoʻāʻo ai i ka pale LCD ʻo ia ka hoʻohana ʻana i kahi kukui LED, kahi e hiki ai ke hoʻohālikelike kiʻekiʻe a me ka dimming pale ʻoi aku ka maikaʻi, e ʻoi aku ka maikaʻi o ka hōʻike ma mua o nā mana o mua. Ke hele nei ka ʻenehana OLED i kahi ʻanuʻu, hāʻawi i ka pale maka a ʻaʻole e hoʻonāwaliwali i ka ʻike.
He ʻokoʻa loa ke kūkulu ʻana i nā hōʻike QLED mai nā hōʻike OLED. Hoʻohana nā hōʻike QLED i nā kiko kikoʻī, e hana ana i ka mālamalama ke hoʻohana ʻia, ʻano like me OLED. Akā, hoʻololi ʻo QLED i ke kukui polū i loaʻa iā ia i kukui keʻokeʻo, i loaʻa ma ka hoʻohana ʻana i nā kiko kikoʻī ʻulaʻula a me ka uliuli. ʻOi aku ka mālamalama o nā hōʻike QLED, akā ʻoi aku ka maikaʻi ma mua o OLED a aia nō i ka hoʻomaka mua o ka hoʻomohala ʻana. ʻO ka ʻokoʻa, ʻike ʻia nā hōʻike OLED iā lākou iho, hōʻike i kā lākou mau kala ponoʻī, a ʻoi aku ka uku. ʻO nā hōʻike LED, ma ka ʻaoʻao ʻē aʻe, he panel i hana ʻia me nā diodes māmā, a hoʻohana maʻamau ʻia i nā papa hoʻolaha a me nā hōʻailona.
