OLED ine yayo yemwenje-inoburitsa kupenya kwakanyanya, yakafara yekuona kona, kukurumidza kupindura, yakaderera simba rekushandisa, uye inogona kugadzirwa inochinjika yekuratidzira michina, inoonekwa kutsiva yemvura yekristaro tekinoroji yakanakira chizvarwa chinotevera chekuratidzira tekinoroji. chikamu chepakati cheOLED chiratidziro chimwe nechimwe chidiki-pixel chine kugona kujekesa-emitting OLED light-emitting element. iyo yakakosha maumbirwo eOLED light-emitting element inosanganisira anode, cathode, uye sandwiched pakati pechiedza-emitting functional layer, iyo light-emitting layer Zvinoenderana nebasa reOLED zvinhu mumudziyo uye chimiro chemudziyo, inogona kusiyaniswa segomba jekiseni layer (HIL), gomba transport layer (HTL), light-emitting layer (EMM) electron kutakura dhayamu (EMLE) electron kutakura zvinhu (EMLE).
Mune maOLED, gomba jekiseni remugodhi uye gomba rekutakura musara rinoshandiswa kuvandudza kushanda kwejekiseni remakomba, nepo jekiseni remajekiseni erekitironi uye dhizaini yekutakura erekitironi zvichishandiswa kuwedzera kushanda kwejekiseni remagetsi. Zvimwe zvezvinhu zvinobudisa chiedza pachazvo zvine basa rekutakura gomba kana kutakura electron, inowanzonzi main luminescent; light-emitting material layer mune shoma shoma yedoped organic fluorescent kana phosphorescent dhayi inogona kugashira kubva kune huru luminescent muviri wekutamisa simba, uye nekutakura uye kuburitsa rumwe ruvara rwechiedza, doped light-emitting material inowanzonziwo muenzi luminescent kana doped light-emitting body.
2. Nheyo dzekutanga dzeOLED Device Light Emission
Voltage inoshandiswa kumudziyo weOLED, uye maburi nemaerekitironi zvinopinzwa muOLED layer kubva kune anode uye cathode yechishandiso, zvichiteerana. Iwo maburi uye maerekitironi mu organic light-emitting material composite uye kusunungura simba, uye kuwedzera simba kutamisa organic chiedza-emitting zvinhu mamorekuru, kuitira kuti vafarire kunyika kufara, uye ipapo exciton kubva kufara mamiriro kudzokera pasi mamiriro, simba muchimiro kusunungurwa, uye pakupedzisira kuziva electroluminescence yeOLED mudziyo.
Kazhinji kutaura, iyo firimu muOLED inosanganisira conductive electrode firimu uye imwe neimwe layer ye organic light-emitting layer material. Parizvino, anodes emidziyo yeOLED akawana kugadzirwa kwakawanda anowanzo gadzirirwa uchishandisa magineti control mitigation tekinoroji. Macathodes uye organic luminescent layers anowanzo gadzirirwa ne vacuum evaporation.
