Yintoni uMboniso we-OLED?

OLED sisishunqulelo se-Organic Light Emitting Diode, elithetha "i-Organic Light Emitting display technology" ngesiTshayina.Imbono yeyokuba umaleko okhupha ukukhanya okuphilayo ufakwe phakathi kwee-electrode ezimbini.Xa ii-electron ezi-positive kunye ne-negative zidibana kwi-organic material, ziyakhupha. ukukhanya.Isakhiwo esisisiseko seOLED kukwenza umaleko we-organic light-emitting material amashumi eenanometers angqindilili kwi-indium tin oxide (ITO) yeglasi njengomaleko okhupha ukukhanya.Ngaphezu kocweyo olukhupha ukukhanya ngumaleko we-electrode yesinyithi enomsebenzi ophantsi, okwenza isakhiwo. njenge sandwich.

iteknoloji ephezulu OLED ukubonisa

I-Substrate (iplastiki ecacileyo, iglasi, i-foil) -I-substrate isetyenziselwa ukuxhasa yonke i-OLED.

I-Anode (i-TRANSPARENT) - I-anode iphelisa i-electron (ikwandisa i-electron "imingxuma") njengoko ikhoyo ngoku ihamba ngesixhobo.

Umaleko wokuthuthwa komngxuma - Olu luhlu lwenziwe ngamamolekyuli ezinto eziphilayo ezithutha "imingxuma" kwi-anode.

Uluhlu lweLuminescent - Lo luhlu lwenziwe ngamamolekyuli ezinto eziphilayo (ngokuchasene neengqungquthela zokuqhuba) apho inkqubo ye-luminescence yenzeka khona.

Umaleko wezothutho ze-Electron - Lo maleko wenziwe ngamamolekyuli ezinto eziphilayo ezithutha ii-electron ukusuka kwi-cathode.

I-Cathodes (enokuthi ibonakale okanye i-opaque, kuxhomekeke kuhlobo lwe-OLED) - Xa ikhoyo ngoku ihamba ngesixhobo, i-cathodes ifaka i-electron kwisiphaluka.

Inkqubo ye-luminescence ye-OLED ihlala inamanqanaba amahlanu alandelayo:

① Inaliti yoMthwali:phantsi kwesenzo sommandla wombane wangaphandle, ii-electron kunye nemingxuma zitofwa kumaleko we-organic functional afakwe phakathi kwe-electrode esuka kwi-cathode kunye ne-anode, ngokulandelelanayo.

② Ukuthuthwa kweCarrier: ii-electron ezitofwayo kunye nemingxuma zifuduka ukusuka kwi-electron transport layer kunye ne-hole transport layer ukuya kwi-luminescent layer, ngokulandelanayo.

③ Ukudityaniswa kwakhona komthwali: emva kokuba ii-electron kunye nemingxunya zifakwe kwi-luminescent layer, zibotshwa kunye ukuze zenze i-electron hole pairs, oko kukuthi, i-excitons, ngenxa yesenzo samandla e-Coulomb.

④ Ukufuduka kwe-Exciton: Ngenxa yokungalingani kwe-electron kunye nokuthuthwa komngxuma, indawo ephambili yokwakhiwa kwe-exciton ihlala ingagubungeli yonke i-luminescence layer, ngoko ke ukufuduka kwe-diffusion kuya kwenzeka ngenxa ye-concentration gradient.

⑤Imitha ye-Exciton yehlisa iifotoni:Inguqu ye-exciton yomitha ekhupha iifotoni kwaye ikhuphe amandla.
