Abavelisi beZixhobo ze-OLED beGlobal baqhuba iNtsha entsha kwiTekhnoloji yokuBonisa i-Next-Gen

IGlobal OLED Equipment Manufacturers Drive Innovation in Display

I-teknoloji ye-Organic Light-Emitting Diode (OLED), eyaziwa njengesizukulwana esilandelayo sesisombululo se-flat-panel ukubonisa emva kwe-CRT, i-PDP, kunye ne-LCD, iyaqhubeka nokuguqula imboni ye-elektroniki kunye nokusebenza kwayo okuphezulu kunye nokuguquguquka. Ukusebenzisa izixhobo ze-organic semiconductor ezikhupha ukukhanya phantsi kwamasimi ombane, i-OLED ibonelela ngoyilo oluluqilima ngokupheleleyo. ukudibanisa iinzuzo zeCRT's umahluko ophezulu kunye LCD's iprofayile encinci, ngelixa ususa imiqobo yelifa.

Ulwakhiwo lwe-OLED kunye nokuSebenza

Isixhobo esiqhelekileyo se-OLED sibandakanya iileyile ezisebenzayo ezininzi, kubandakanya i-anode, i-injection ye-injection yomngxuma (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 maleko zenzelwe ukwenza a“izinyuko”Ulwakhiwo lwenqanaba lamandla (Umfanekiso 1), ukuququzelela ukuhlanganiswa kwakhona kwemingxunya kunye nee-electron ngaphakathi kwinqanaba elikhuphayo ukuvelisa ukukhanya. Ubuchwephesha be-doping obuphezulu bokwandisa ngakumbi amanqanaba amandla (iTheyibhile 1-2), iphucula ukusebenza kakuhle kwesixhobo kunye nobomi.

Izixhobo ezingundoqo zokuVelisa

Imveliso ye-OLED ixhomekeke kwizixhobo ezikhethekileyo ezilungiselelwe zombini i-matrix (PM-OLED) kunye ne-matrix esebenzayo (AM-OLED) ubuchwepheshe. Iinkqubo ezibalulekileyo ziquka:

I-PM-OLED: I-Evaporation ye-Organic kunye nezixhobo zokufaka i-encapsulation.

AM-OLED:  Iinkqubo zokubeka: Iiplatifti ze-sputtering, i-plasma-enhanced chemical vapor deposition (PECVD), kunye ne-vacuum thermal evaporation (VTE) ye-thin-film transistor (TFT) layers.

Izixhobo zokuyenza ipateni: Iicoaters, ii-exposure machines, kunye ne-etchers ezomileyo/ezimanzi zokwenziwa kwesekethe ye-TFT.

Iisistim ze-Annealing: Iifarnaces, imibhobho yerhasi, kunye nezixhobo zokucoca ngelaser.

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 koovulindlela boshishino abaqhuba izinto ezintsha ekubekweni okuchanekileyo, ukwenza iipateni, kunye novavanyo lobuchwepheshe. Iinkampani eziphambili ziye zaqinisa izikhundla zazo ngokuphumelela kwimveliso ephezulu kunye nokwandisa isivuno.. YiIbaluleke kakhulu ekuveliseni iiphaneli ze-OLED ezininzi ezisetyenziswa kwii-smartphones, iiTV, kunye nezixhobo ezinokunxitywa.
