Yini i-OLED Display?

I-OLED isifinyezo se-Organic Light Emitting Diode, okusho ukuthi “i-Organic Light Emitting display technology” ngesiShayina. Umbono wukuthi ungqimba olukhipha ukukhanya okuphilayo luhlanganiswe phakathi kwama-electrode amabili. ukukhanya.Isakhiwo esiyisisekelo seI-OLED ukwenza ungqimba lwezinto eziphilayo ezikhipha ukukhanya okungamashumi ama-nanometers awugqinsi engilazini ye-indium tin oxide (ITO) njengongqimba olukhipha ukukhanya.Ngaphezu kwesendlalelo esikhipha ukukhanya kunongqimba lwama-electrode ensimbi anomsebenzi ophansi, akha isakhiwo. njengesemishi.

I-Substrate (ipulasitiki esobala, ingilazi, i-foil) - I-substrate isetshenziselwa ukusekela yonke i-OLED.

I-Anode (TRANSPARENT) - I-anode iqeda ama-electron (yandisa "izimbobo" ze-electron) njengoba okwamanje igeleza kudivayisi.

Isendlalelo sokuthutha izimbobo - Lesi sendlalelo sakhiwe ngama-molecule ezinto eziphilayo ezithutha "izimbobo" zisuka ku-anode.

Isendlalelo seLuminescent - Lesi singqimba sakhiwe ngama-molecule ezinto eziphilayo (ngokungafani nezendlalelo eziqhutshwayo) lapho inqubo ye-luminescence yenzeka khona.

Isendlalelo sezokuthutha ze-electron - Lolu ungqimba lwakhiwe ngama-molecule ezinto eziphilayo ahambisa ama-electron esuka ku-cathode.

Ama-Cathodes (okungaba obala noma opaque, kuye ngohlobo lwe-OLED) - Uma okwamanje kugeleza ocingweni, ama-cathode ajova ama-electron kusekethe.

Inqubo ye-luminescence ye-OLED ivamise ukuba nezigaba ezinhlanu ezilandelayo:

① Umjovo wenkampani yenethiwekhi:ngaphansi kwesenzo senkundla kagesi yangaphandle, ama-electron nezimbobo kufakwa ungqimba olusebenzayo lwemvelo oluhlanganiswe phakathi kwama-electrode asuka ku-cathode ne-anode, ngokulandelana.

② Ukuthuthwa kwenkampani yenethiwekhi: ama-electron ajovwe nezimbobo zisuka kungqimba lwezokuthutha lwe-electron kanye nesendlalelo sokuthutha imbobo ziye kungqimba lwe-luminescent, ngokulandelana.

③ Ukuhlanganisa kabusha kwenkampani yenethiwekhi: ngemva kokuba ama-electron nezimbobo kujovwe ungqimba lwe-luminescent, ahlanganiswa ukuze akhe amapheya embobo yama-electron, okungukuthi, ama-exciton, ngenxa yesenzo samandla e-Coulomb.

④ Ukufuduka kwe-Exciton: Ngenxa yokungalingani kokuthuthwa kwe-electron nembobo, isifunda esikhulu sokwakheka kwe-exciton ngokuvamile asibandakanyi lonke ungqimba lwe-luminescence, ngakho-ke ukufuduka kokusabalalisa kuzokwenzeka ngenxa ye-concentration gradient.

⑤Imisebe ye-Exciton ilimaza ama-photon:Inguquko ye-exciton radiative ekhipha ama-photon futhi ikhiphe amandla.
