Loaʻa i ka OLED kona ʻālohilohi kiʻekiʻe e hoʻomālamalama ana, ākea ka nānā ʻana, pane wikiwiki, hoʻemi haʻahaʻa i ka ikehu, a hiki ke hana ʻia i nā mea hōʻike maʻalahi, ua manaʻo ʻia e pani i ka ʻenehana aniani wai kūpono no ka hanauna hou o ka ʻenehana hōʻike. ʻO ka ʻāpana koʻikoʻi o ka hōʻike OLED ʻo kēlā me kēia sub-pixel me ka hiki ke hoʻomālamalama i ka mea hoʻomālamalama kukui OLED. ʻO ke ʻano kumu o ka OLED light-emitting element e pili ana i ka anode, cathode, a me ka sandwiched ma waena o ka papa hana kukui-emitting, ʻo ia ka papa kukui E like me ka hana o nā mea OLED i loko o ka hāmeʻa a me ke ʻano o ka hāmeʻa, hiki ke hoʻokaʻawale ʻia e like me ka hole injection layer (HIL), hole transport layer (HTL), light-emitting layer (EML) electron transport layer (ETLLE) electron transport layer (ETLE).
I loko o nā OLED, hoʻohana ʻia ka ʻāpana hole a me ka hole transport layer no ka hoʻomaikaʻi ʻana i ka maikaʻi o ka injection o nā lua, ʻoiai ke hoʻohana ʻia nei ka ʻāpana electron injection a me ka layer transport electron e hoʻomaikaʻi i ka pono o ka injection o nā electrons. ʻO kekahi o nā mea hoʻomāmā kukui iā lākou iho ka hana o ka lawe puka a i ʻole ka lawe electron, i kapa ʻia ʻo ka luminescent nui; Hiki ke loaʻa nā mea hoʻoheheʻe kukui i loko o kahi liʻiliʻi o ka doped organic fluorescent a i ʻole phosphorescent dyes mai ke kino luminescent nui o ka hoʻololi ʻana i ka ikehu, a ma ka hopu ʻana a me ka hoʻokuʻu ʻana i kahi kala ʻē aʻe o ke kukui, ʻo ka doped light-emitting mea maʻamau i kapa ʻia ʻo ka luminescent malihini a i ʻole kino doped light-emitting kino.
2. Nā Kumu Kumu o ka OLED Device Light Emission
Hoʻopili ʻia kahi volta i ka hāmeʻa OLED, a hoʻokomo ʻia nā lua a me nā electrons i loko o ka papa OLED mai ka anode a me ka cathode o ka hāmeʻa, kēlā me kēia. ʻO nā puka a me nā electrons i loko o ka mea hoʻoheheʻe kukui kūlohelohe i hui pū ʻia a hoʻokuʻu i ka ikehu, a me ka hoʻololi hou ʻana i ka ikehu e hoʻololi i nā molekala uila, no laila e hauʻoli lākou i ke kūlana hauʻoli, a laila ka exciton mai ka hauʻoli i hoʻi i ka mokuʻāina, ka ikehu i ke ʻano o ka hoʻokuʻu ʻana, a ʻike hope i ka electroluminescence o ka mea OLED.
ʻO ka ʻōlelo maʻamau, ʻo ke kiʻiʻoniʻoni ma OLED e loaʻa i kahi kiʻiʻoniʻoni electrode conductive a me kēlā me kēia papa o nā mea papa kukui-emitting. I kēia manawa, hoʻomākaukau ʻia nā anodes o nā mea OLED i loaʻa i ka hana nui me ka hoʻohana ʻana i ka ʻenehana hoʻemi hoʻokele magnetic. Hoʻomākaukau maʻamau ʻia nā Cathodes a me nā papa luminescent organik e ka hoʻoheheʻe ʻia ʻana.
