OLED ke khutsufatso ea Organic Light Emitting Diode, e bolelang "Organic Light Emitting display technology" ka Sechaena.Mohopolo ke hore organic light-emitting layered between two electrode khanya.Mohaho oa motheo oaOLED ke ho etsa lera la lintho tse phelang le khanya e etsang mashome a li-nanometer tse teteaneng holim'a khalase ea indium tin oxide (ITO) e le lesela le ntšang khanya. joalo ka sandwich.
ponts'o ea theknoloji e phahameng ea OLED
Substrate (polasetiki e bonaletsang, khalase, foil) - Substrate e sebelisoa ho ts'ehetsa OLED eohle.
Anode (TRANSPARENT) - Anode e felisa li-electrone (e eketsa "likoti" tsa elektronike) ha hona joale e phalla ka sesebelisoa.
Hole transport layer - Lera lena le entsoe ka limolek'hule tsa lintho tse phelang tse tsamaisang "likoti" ho tloha ho anode.
Lera la Luminescent - Lera lena le entsoe ka limolek'hule tsa lintho tse phelang (ho fapana le lihlopha tsa conductive) moo ts'ebetso ea luminescence e etsahalang.
Lera la lipalangoang tsa elektrone - Lera lena le entsoe ka limolek'hule tsa lintho tse phelang tse tsamaisang lielektrone ho tloha ho cathode.
Li-cathodes (tse ka bang pepeneneng kapa tse opaque, ho itšetlehile ka mofuta oa OLED) - Ha hona joale ho phalla ka sesebelisoa, li-cathodes li kenya li-electrone ho potoloha.
Ts'ebetso ea luminescence ea OLED hangata e na le mekhahlelo e mehlano ea mantlha:
① Ente ea Carrier: Tlas'a ts'ebetso ea lebala la motlakase le kantle, lielektrone le masoba li kenngoa ka har'a lera le sebetsang le kentsoeng lipakeng tsa li-electrode ho tloha ho cathode le anode, ka ho latellana.
② Lipalangoang tsa lipalangoang: li-elektronike tse kentsoeng le masoba li falla ho tloha karolong ea lipalangoang tsa elektronike le lera la lipalangoang tsa sekoti ho ea lera la luminescent, ka ho latellana.
③ Recombination ea Carrier: ka mor'a hore lielektrone le masoba li kenngoe ka har'a lesela la luminescent, li tlamahanngoa ho etsa lipara tsa likoti tsa elektronike, ke hore, li-exciton, ka lebaka la ketso ea matla a Coulomb.
④ Ho falla ha Exciton: Ka lebaka la ho se leka-lekane ha lipalangoang tsa elektronike le mekoti, sebaka se seholo sa sebopeho sa exciton hangata ha se koahele lera lohle la luminescence, kahoo phallo e pharalletseng e tla etsahala ka lebaka la khatello ea maikutlo.
⑤Mahlaseli a Exciton a thefula li-photon: Phetoho ea exciton radiative e ntšang lifoto le ho ntša matla.
