Abavelisi bezixhobo ze-OLED zehlabathi baqhuba ubugcisa obutsha kwiSiboniso
Itekhnoloji ye-Organic Light-Emitting Diode (OLED), eyaziwa njengesisombululo sesiboniso se-flat-panel esilandelayo emva kwe-CRT, i-PDP, kunye ne-LCD, iyaqhubeka nokuguqula ishishini le-elektroniki ngokusebenza kwayo okuphezulu kunye nokuguquguquka. Isebenzisa izixhobo ze-semiconductor ze-organic ezikhupha ukukhanya phantsi kwamacandelo ombane, i-OLED inikezela ngoyilo oluqinileyo ngokupheleleyo. ukudibanisa iingenelo zeCRT'umahluko ophezulu kunye ne-LCD'iprofayili encinci, ngelixa kususwa iingxaki zelifa.
Ulwakhiwo lwe-OLED kunye nokusebenza kwayo
Isixhobo esiqhelekileyo se-OLED siqulathe iileya ezininzi ezisebenzayo, kuquka i-anode, i-hole injection layer (HIL), i-hole transport layer (HTL), i-organic emissive layer (EL), i-electron transport layer (ETL), i-electron injection layer (EIL), kunye ne-cathode. Ezi leya zenzelwe ukudala i-“izitebhisi"ulwakhiwo lwenqanaba lamandla (Umzobo 1), oluququzelela ukuhlanganiswa kwakhona kwemingxunya kunye nee-elektroni ngendlela efanelekileyo ngaphakathi komaleko okhuphayo ukuvelisa ukukhanya. Iindlela eziphambili zokusebenzisa i-doping ziphucula ngakumbi amanqanaba amandla (Iitheyibhile 1-2), ziphucula ukusebenza kakuhle kwesixhobo kunye nobomi baso.
Izixhobo Eziphambili Zokuvelisa
Imveliso ye-OLED ixhomekeke kwizixhobo ezikhethekileyo kakhulu ezenzelwe zombini ubuchwepheshe be-passive matrix (PM-OLED) kunye ne-active matrix (AM-OLED). Iinkqubo ezibalulekileyo ziquka:
I-PM-OLED: Izixhobo zokufudumeza kunye nezixhobo zokugquma izinto eziphilayo.
I-AM-OLED: Iinkqubo zokususa: Iiplatifomu zokutshiza, i-plasma-enhanced chemical vapor deposition (PECVD), kunye ne-vacuum thermal evaporation (VTE) yee-thin-film transistor (TFT) layers.
Izixhobo zokulinganisa: IiCoaters, oomatshini bokutyhila, kunye nee-etchers ezomileyo/ezimanzi zokwenza i-TFT circuit.
Iinkqubo zokuncamathela: Iifurnaces, imibhobho yegesi, kunye nezixhobo zokuncamathela nge-laser.
Uvavanyo kunye nokulungiswa: Abavavanyi bombane be-TFT, abahlalutyi be-OLED optical, kunye noomatshini bokulungisa i-laser.
Ikhonkco lokubonelela ngezixhobo ze-OLED kwihlabathi liphela lilawulwa ngabavelisi abakhethekileyo eMzantsi Korea naseJapan, ikhaya labaqalisi beli shishini abaqhuba ubuchule kwitekhnoloji yokubeka ngokuchanekileyo, ukwenza iipateni, kunye nokuvavanya. Iinkampani eziphambili ziqinise isikhundla sazo ngokuphumelela kwimveliso ephezulu kunye nokwenza ngcono isivuno.. Yizibalulekile kwiiphaneli ze-OLED ezivelisa ngobuninzi ezisetyenziswa kwiifowuni eziphathwayo, iiTV, kunye nezixhobo ezinxitywayo.
