Cov Chaw Tsim Khoom Siv OLED Thoob Ntiaj Teb Tsav Kev Tsim Kho Tshiab hauv Kev Tso Tawm
Cov thev naus laus zis Organic Light-Emitting Diode (OLED), uas tau lees paub tias yog tiam tom ntej ntawm cov zaub tiaj tiaj tom qab CRT, PDP, thiab LCD, txuas ntxiv hloov pauv kev lag luam hluav taws xob nrog nws cov kev ua tau zoo tshaj plaws thiab kev hloov pauv ntau yam. Siv cov khoom siv organic semiconductor uas tso tawm lub teeb nyob rau hauv cov teb hluav taws xob, OLED muab cov qauv tsim khoom khov kho tag nrho. kev sib txuas cov txiaj ntsig ntawm CRT's siab sib piv thiab LCD's profile nyias nyias, thaum tshem tawm cov teeb meem qub txeeg qub teg.
OLED Cov Qauv thiab Kev Ua Haujlwm
Ib qho khoom siv OLED ib txwm muaj ntau txheej ua haujlwm, suav nrog anode, qhov txhaj tshuaj (HIL), qhov thauj mus los txheej (HTL), organic emissive txheej (EL), electron transport txheej (ETL), electron injection txheej (EIL), thiab cathode. Cov txheej no tau tsim los tsim ib qho"ntaiv"cov qauv theem zog (Daim Duab 1), pab txhawb kev sib koom ua ke ntawm cov qhov thiab cov electrons hauv cov txheej emissive los tsim lub teeb. Cov txheej txheem doping siab heev ntxiv txhim kho cov theem zog (Cov Lus Qhia 1-2), txhim kho kev ua haujlwm ntawm cov khoom siv thiab lub neej ntev.
Cov Khoom Siv Tsim Khoom Tseem Ceeb
Kev tsim OLED vam khom cov khoom siv tshwj xeeb uas tsim los rau ob qho tib si passive matrix (PM-OLED) thiab active matrix (AM-OLED). Cov txheej txheem tseem ceeb suav nrog:
PM-OLED: Cov cuab yeej ua kom cov organic evaporation thiab encapsulation.
AM-OLED: Cov txheej txheem tso tawm: Sputtering platforms, plasma-enhanced chemical vapor deposition (PECVD), thiab vacuum thermal evaporation (VTE) rau cov txheej nyias-film transistor (TFT).
Cov cuab yeej ua qauv: Cov txheej txheej, cov tshuab ua kom pom tseeb, thiab cov tshuab txiav qhuav/ntub rau kev tsim khoom siv hluav taws xob TFT.
Cov txheej txheem annealing: Cov cub tawg, cov kav dej roj, thiab cov khoom siv laser annealing.
Kev kuaj thiab kho: Cov cuab yeej kuaj hluav taws xob TFT, cov cuab yeej ntsuas hluav taws xob OLED, thiab cov tshuab kho laser.
Cov khoom siv OLED thoob ntiaj teb yog tswj hwm los ntawm cov chaw tsim khoom tshwj xeeb hauv Kaus Lim Qab Teb thiab Nyiv Pooj, uas yog lub tsev rau cov thawj coj hauv kev lag luam uas tsav tsheb tsim kho tshiab hauv kev tso tawm qhov tseeb, qauv, thiab kev sim cov thev naus laus zis. Cov tuam txhab ua lag luam tau ua kom lawv txoj haujlwm ruaj khov los ntawm kev tshawb pom tshiab hauv kev tsim khoom siab thiab kev ua kom zoo dua qub.Nws yogtseem ceeb rau kev tsim cov OLED panels loj uas siv rau hauv cov xov tooj ntse, TVs, thiab cov khoom siv hnav tau.
