IGlobal OLED Equipment Manufacturers Drive Innovation in Display

Ubuchwepheshe be-Organic Light-Emitting Diode (OLED), obaziwa njengesixazululo sesizukulwane esilandelayo sephaneli eyisicaba esilandela i-CRT, i-PDP, ne-LCD, buyaqhubeka nokuguqula imboni yezogesi ngokusebenza kwayo okuphakeme nokuguquguquka. Isebenzisa izinto ezisetshenziswayo ze-organic semiconductor ezikhipha ukukhanya ngaphansi kwamasimu kagesi, i-OLED inikeza idizayini yesimo esiqinile ngokuphelele. ukuhlanganisa izinzuzo CRT's umehluko ophezulu kanye ne-LCD's iphrofayili encane, ngenkathi isusa izithiyo zefa.

Isakhiwo se-OLED nokusebenza

Idivayisi ejwayelekile ye-OLED ihlanganisa izendlalelo ezisebenzayo eziningi, okuhlanganisa i-anode, ungqimba lomjovo wembobo (HIL), ungqimba lwe-hole transport (HTL), ungqimba oluphuma ku-organic emissive (EL), ungqimba lwe-electron transport (ETL), ungqimba lomjovo we-electron (EIL), kanye ne-cathode. Lezi zingqimba zenzelwe ukwakha a“izitebhisi”ukwakheka kwezinga lamandla (Fig. 1), okusiza ukuhlanganisa kabusha okusebenzayo kwezimbobo nama-electron ngaphakathi kwesendlalelo esikhipha umoya ukukhiqiza ukukhanya. Izindlela zokusebenzisa izidakamizwa ezithuthukile zithuthukisa futhi amazinga wamandla (Amathebula 1-2), athuthukisa ukusebenza kahle kwedivayisi nempilo yokuphila.

Izisetshenziswa Zokukhiqiza Ezibalulekile

Ukukhiqizwa kwe-OLED kuncike kumishini ekhetheke kakhulu eyenzelwe kokubili ubuchwepheshe be-matrix ye-passive (PM-OLED) kanye ne-active matrix (AM-OLED). Amasistimu abalulekile afaka:

I-PM-OLED: I-Organic evaporation kanye namathuluzi e-encapsulation.

I-AM-OLED:  Amasistimu we-deposition: Amapulatifomu e-Sputtering, i-plasma-enhanced chemical vapor deposition (PECVD), kanye ne-vacuum thermal evaporation (VTE) yezendlalelo ze-thin-film transistor (TFT).

Amathuluzi okwenza iphethini: Ama-coaters, imishini yokuchayeka, nezinsimbi ezomile/ezimanzi zokwenziwa kwesekethe ye-TFT.

Amasistimu we-Annealing: Iziko, amapayipi egesi, kanye nemishini yokudonsa nge-laser.

Ukuhlola nokulungisa: Abahloli bakagesi be-TFT, abahlaziyi be-OLED optical, nemishini yokulungisa i-laser.

Uchungechunge lokuhlinzekwa kwemishini ye-OLED yomhlaba wonke luphethwe abakhiqizi abakhethekile eSouth Korea naseJapan, ikhaya lamavulandlela embonini ashayela ukuqamba okusha ekubekweni okunembayo, amaphethini, kanye nobuchwepheshe bokuhlola. Izinkampani ezihamba phambili ziqinise izikhundla zazo ngokuphumelela ekukhiqizeni okuphezulu kanye nokwenza ngcono isivuno.. Ikonakubalulekile kumaphaneli e-OLED akhiqiza ngobuningi asetshenziswa kuma-smartphone, ama-TV, namadivayisi agqokekayo.
