Organic Light Emitting Diode (OLED) thiab lub cev muaj zog lub cev organic teeb emitting diode (AMOLED) lub cev muaj zog lub cev teeb-emitting diodes (LEDs) hu ua yees duab ntxiv tom ntej, xws li Samsung Electronics, Samsung SDI, LG, thiab Philips. Tag nrho cov xa zoo qhov tseem ceeb rau cov qauv tshiab no.
Cov kev sib raug zoo thiab sib txawv ntawm AMOLED technology thiab OLED yog dab tsi?
AMOLED
Txawm hais tias cov LEDs muaj feem ntau nyob rau hauv txhua txhua hnub, txhua lub LED me me loj ntawm qhov screen thiab muab faib ua peb pawg pixel liab, xim ntsuab thiab xiav, thiab tom qab ntawd tas cov xim txawv, thiab qhov kev hloov ntawm sub-pixels txawv. Cov hom yuav los cuam tshuam rau tag nrho cov duab. Tus O hauv AMOLED nruab nrab yog Organic, uas yog "organic." Tsuas pub, ib cov yeeb yaj kiab los ua cov yeeb yaj kiab los siv rau ntawm cov kev tawm dag zog thiab kev pom zoo los ntawm lub hom phiaj ntawm lub teeb emission.
AM sawv kos rau Active Matrix thiab yog ntu ntawm Passive Matrix. Nws yog hais txog txoj kev txhua pliag OLED. Nyob hauv Pas Kev Lom Zem, qhov kev tswj ntawm txhua tus pixel yog tiav los ntawm ib qho kev sib txuas ntawm lub electrode mus cuag cov nqi thiab tawm ntawm ib qho pixel. Zuag qhia tag nrho, txoj kev tswj tus Txheej Txheem Pas nrig yog qeeb qeeb thiab kev tswj kev tswj kuj tseem me me. Tsis zoo li cov Passive Matrix, Active Matrix ntxiv TFT thiab capacitor khaubncaws sab nraud povtseg ntawm txhua lub laujkaub kom thaum twg ib qho kev sib txuas ua kom muaj peev xwm mus qhib tau cov duab tsho, tus txheej txheem ntawm lub pixel nyob rau hauv pixel yuav tuaj yeem ua haujlwm tshiab. Tswj lub xeev ntawm them nyiaj tau sai thiab ntau dua pixel teeb pom kev zoo tswj.
OLED
Organic Light Emitting Diodes (OLEDs) kuj yog hu ua Organic Electro-Luminescence Displays (OLEDs) thiab Organic Electroluminesence Displays (OLEDs). Cov kua siv lead ua kua (LCD) yog hom sib txawv ntawm lub teeb emitting txuj ci. OLED tau pom los ntawm Ching W. Tang, xibfwb Suav-American, nyob rau hauv laboratory hauv xyoo 1983, thiab pib tshawb nrhiav OLED. OLED tso tawm tshuab muaj qhov zoo ntawm kev luminescence, lub qhov laj kab dav dav dav, qhov yuav luag zoo sib xws, txo hwj chim ntau dua, thiab ceev ceev heev. Lub ntsiab zoo ntawm OLED npo yog qhov controllability siab ntawm pixels, txhua lub pixel yuav tau ntawm nws tus kheej hloov, yog li ua tiav ntau xim dub thiab zoo dua. Tsis tas li ntawd, kev siv hluav taws xob muaj peev xwm txo tau los ntawm kev xa tawm tsis muaj pixels thaum lub vijtsam tso tawm. Nyob rau tib lub sijhawm, vim tsawg dua ntawm cov khaubncaws sab nraud povtseg ntawm lub khoos phis tawj, lub teeb hloov ntawm lub cev kuj zoo dua, uas yog qhov zoo rau kev ua kom pom ci ntsa iab dua thiab lub davhlau saib xyuas.
OLED cov ntxaij vab tshaus yeej ua tau zoo heev thiab zoo tagnrho rau kev siv xovtooj xws li cov xovtooj ntawm tes. Tsis tas li ntawd xwb, vim tias tsis muaj teeb meem backlight txheej thiab nrog cov khoom zoo ntawm cov yas substrates, OLEDs muaj qhov zoo tshaj plaws nyob rau hauv cov ntxaij vab tshaus yooj yim, muab cov xov tooj ntawm tes thiab cov ris tsho tseem ceeb tshaj plaws nyob rau hauv cov ntaub ntawv ntawm yav tom ntej.
Qhov txawv ntawm ob
AMOLED belongs rau OLED, tab sis qhov rov qab tsis yog. Cias muab, OLED cov cuab yeej siv xws li PMOLED thiab AMOLED. PMOLED tsis xav tau ib daim npog TFT (txawv ntawm cov kua qaum ua kua dej), tiam sis qhov loj me tsis tuaj yeem ua tau ntau heev; qhov luaj li cas ntawm AMOLED yuav ua tau loj heev. PMOLED tsuas yog tshwm sim nyob rau hauv thaum ntxov dual-mobile xov tooj rau me me ntxaij vab tshaus. Tam sim no mobile TVs siv tshuab AMOLED.
OLED yog ib qho teeb ci organic-emitting diode. Nws cov khoom siv hluav taws xob yog ib qho khoom siv organic-emitting, uas yog qhov sib piv rau LED lub teeb-emitting diodes. Ntev npaum li cas tus OLED siv nrog qhov tseeb qhov hluav taws xob ntawm qhov anode thiab cathode, nws emits lub teeb. Qhov no yog tib yam li qhov teeb ci. Kom nws ua teeb meem, nws yuav ua haujlwm.
AMOLED yog ib lub teeb ci uas muaj kab xo ua kom muaj pa tawm. Nws tsis yog yuav tsum tau ntxiv cov teeb liab ntxiv, tab sis kuj yuav tsum tau muab ib qho chaw ntxiv kom lub diodes tuaj yeem ncav cuag lub xeev ua haujlwm. Thaum muab lub teeb ci los sis lub teeb liab, nws yuav taws lossis kaw. Nws tsis yog ib qho zoo sib xws. Nws ua haujlwm zoo li lub TV. Koj muab nws lub teeb liab, tab sis koj tsis tuaj yeem pom nws. Koj tsuas saib tau nws. Tab sis tsuas yog lub hwj chim, tsis muaj cable signals, tsis muaj cov kev pab cuam pom.
OLED kuj muaj PMOLED "passive array organic teeb emitting diode board saum npoo". Ib tug yog lub teeb ceem tswj thiab lwm qhov yog lub teeb nrooj tiv thaiv. Peb lub xov tooj ntawm tes feem ntau yog hais txog AMOLED. Lub npe hu ua OLED yog nyob ntawm iav substrate ntawm qhov screen coated nrog ib txheej ntawm cov ntaub ntawv organic (cov khoom no yog kim heev hais), thiab ces AMOLED yog ntxiv AM technology ntawm OLED vaj huam sib luag, cov tswj kev ua haujlwm.
