OLED ʻO ia ka pōkole o Organic Light Emitting Diode, ʻo ia hoʻi "Organic Light Emitting display technology" ma ka ʻōlelo Kina. māmā.ʻO ka hana kumu oOLED ʻO ka hana ʻana i kahi papa o nā mea hoʻomāmā kukui kūlohelohe he ʻumi nanometer ka mānoanoa ma ke aniani indium tin oxide (ITO) ma ke ʻano he papa kukui. like me ka sandwich.
hōʻike ʻenehana kiʻekiʻe OLED
Substrate (plastic transparent, aniani, foil) - Hoʻohana ʻia ka substrate e kākoʻo i ka OLED holoʻokoʻa.
Anode (TRANSPARENT) - Hoʻopau ka anode i nā electrons (hoʻonui i nā "holes" electron) i ke kahe ʻana o kēia manawa ma ka hāmeʻa.
Lapa lawe puka - Ua hana ʻia kēia ʻāpana me nā molekele waiwai e lawe i nā "puka" mai ka anode.
Papa luminescent - Ua hana ʻia kēia ʻāpana me nā molekele mea ola (e kūʻē i nā papa conductive) kahi e hana ai ke kaʻina hana luminescence.
Electron transport layer - Ua hana ʻia kēia ʻāpana me nā molekele waiwai e lawe i nā electrons mai ka cathode.
Cathodes (hiki ke akaka a opaque paha, e pili ana i ke ʻano o ka OLED) – Ke holo ka ʻāwī ma o ka hāmeʻa, hoʻokomo nā cathodes i nā electrons i ke kaapuni.
ʻO ke kaʻina hana luminescence o OLED e loaʻa i nā pae kumu ʻelima:
① Hoʻokomo ʻia ka mea lawe: ma lalo o ka hana o kahi kahua uila waho, ua hoʻokomo ʻia nā uila a me nā lua i loko o ka papa hana kūlohelohe i hoʻopaʻa ʻia ma waena o nā electrodes mai ka cathode a me ka anode.
② Ka lawe ʻana i ka mea lawe: ua neʻe nā electron i hoʻokomo ʻia a me nā puka mai ka papa lawe electron a me ka papa lawe puka i ka papa luminescent, kēlā me kēia.
③ Hoʻohui hou ʻana o ka mea lawe: ma hope o ka hoʻokomo ʻia ʻana o nā electrons a me nā puka i loko o ka papa luminescent, ua hoʻopaʻa ʻia lākou e hana i nā lua electron hole, ʻo ia hoʻi, nā excitons, ma muli o ka hana a Coulomb ikaika.
④ ʻO ka neʻe ʻana o Exciton: Ma muli o ke kaulike ʻole o ka lawe ʻana i ka electron a me ka hole, ʻaʻole i uhi ʻia ka ʻāina hoʻokumu exciton nui i ka papa luminescence holoʻokoʻa, no laila e hiki mai ka neʻe diffusion ma muli o ka gradient concentrate.
⑤Exciton radiation degenerates photons: He hoʻololi radiative exciton e hoʻopuka ana i nā kiʻi a hoʻokuʻu i ka ikehu.
