Niaj hnub no, lub lag luam LED yog saturated, nqi kev tsov kev rog muaj kev sib raug zoo, thiab nyiaj margins yog tas li yog compressed. Nyob rau hauv cov ntsiab lus no, OLED yuav tsum los ntawm lub sijhawm dhau los, qhib cov kev lag luam tshiab rau cov lag luam loj kom muaj ntau txoj kev lag luam, ces qhov sib txawv ntawm OLED thiab LED thaum kawg, lub hauv paus ntsiab lus ntawm lawv cov teeb, cia peb kawm ua ke
LED siv hlau cov ntaub ntawv, thaum siv cov khoom siv organic, lub hauv paus ntsiab lus ntawm ob yog tib yam, qhov txawv yog qhov ntawd tsis yog qhov yuav tsum ua kom muaj teeb pom kev, thiab nws tus kheej lub teeb, yog muaj lub teeb -emitting diode array. Brightness yog siab tshaj li tus LCD LCD Thickness thinner yog ib qho kev hloov rau LED cov ntxaij vab tshaus LCD yav tom ntej. LED lub vijtsam LCD xav tau ib lub teeb, qhov ci ntsa iab yog qhov tseemceeb, thiab cov duab tsis muaj zog thaum nruab hnub. Txawm li cas los, nws yog tam sim no feem ntau siv dav.
???????? LED cov kev siv tau muab faib ua ob pawg: Ua ntej, LED daim ntawv thov raj, nrog rau kev teeb pom kev zoo LED, infrared LED, thiab lwm yam .; qhov no yog qhov pom ntawm LED, tam sim no, Tuam Tshoj tseem muaj ib qho kev sib txawv ntawm cov txheej txheem LED khoom tsim thiab thoob ntiaj teb, tiam sis kom deb npaum li cov lus qhia txog qhov teeb meem, Tuam Tshoj tus tsim thiab kev siv technology ntau ntau yeej muaj nyob hauv lub ntiaj teb.
LED lub teeb pom kev yog ib qho khoom tso tawm ntawm lub teeb tawm ntawm lub teeb tawm. Nws txais qhov low-voltage scan tsav thiab muaj cov nram qab no nta: tsis muaj zog noj, kev pab cuam lub neej ntev, qis dua, siab ua kom siab, tsis ua haujlwm, saib loj saib, thiab pom nrug.
OLED: Organic Light Emitting Display, ib lub teeb ci organic emitting, yog ib qho tshiab tawm ntawm cov xov tooj txawb LCD thiab raug hu ua "Dream Monitor." OLED zaub technology txawv ntawm cov qauv duab hauv cov duab uas nws tsis tas yuav tsum muaj lub teeb pom kev, siv cov txheej txheem uas muaj roj ntau ntawm cov khoom siv, thiab muaj ib qho iav substrate los yog kev ua haujlwm tshwj xeeb yas substrate. Thaum ib qho hluav taws xob tam sim no dhau los, cov khoom siv organic tawm ntawm lub teeb. Tsis tas li ntawd, qhov screen OLED zaub yuav ua tau sib zog thiab thinner, muaj ib qhov loj saib qhov loj, thiab tuaj yeem txuag tau lub zog. Txawm li cas los xij, OLEDs nrog cov yees zoo dua yuav hloov LCDs xws li TFTs yav tom ntej, organic light-emitting display technologies muaj shortcomings xws li kev pab cuam luv luv lub neej thiab cov teeb meem loj hauv cov npo loj.
OLED: Kuj hu ua "organic EL" zaub, nws yog Lub Teeb Duab Tshav Ntsuam Zoo.
Cov qauv ntawm cov OLED yog tsim los ntawm cov thev khis thiab cov Hoob Tig (ITO) nrog ib tus neeg ua haujlwm, uas yog txuas nrog lub tshuab hluav taws xob zoo, thiab lwm yam hlau cathode, uas yog tsim rau hauv ib lub qauv nyuaj. Tag nrho cov txheej txheej muaj xws li lub qhov kev thauj (HTL), lub teeb emitting txheej (EL) thiab ib qho hluav taws xob xa hluav taws (ETL). Thaum lub hwj chim muab rau qhov kev tsim nyog, qhov zoo thiab qhov cathode tsub raug ua ke nyob rau hauv lub teeb emitting txheej los ua lub teeb, thiab xim liab, ntsuab, thiab xiav RGB thawj xim yog tsim raws li cov khoom noj sib txawv los ua cov xim yooj yim. Cov cwj pwm ntawm OLEDs yog tus kheej-illumination, tsis zoo li TFT LCDs uas yuav tsum tau siv cov nrob qaum, kom pom kev thiab ci ntsa iab, ua raws li kev tsis tshua muaj qhov muaj zog thiab kev txuag hluav taws xob, kev ua haujlwm nrog cov lus teb ceev ceev, nyhav, thin thickness, yooj yim siv, thiab tus nqi qis Etc., yog pom tias yog ib qho ntawm cov khoom pheej cog lus tshaj plaws ntawm xyoo pua 21st.
Lub teeb emitting txujci ntawm cov organic teeb emitting diode yog zoo ib yam li cov teebmeem inorganic teeb emitting diode. Thaum lub caij no raug rau kev ncaj nraim ntawm lub sijhawm tam sim no (DC), lub zog ntawm qhov siv hluav taws xob yuav tsav cov electrons thiab qhov rau qhov tshuaj ntawm cov cathode thiab anode, raws li, thaum ob qho tib si sib tham. Ua ke nrog, ua kom hu ua Electron-Hole Capture. Thaum cov tshuaj molecule zoo siab los ntawm sab nraud lub zog, yog hais tias lub electron spin yog nrog lub xeev hauv lub xeev electron, nws yog ib tug singlet, thiab lub teeb tawm tawm hu ua Fluorescence; Lub xeev electrons thiab hauv av electron spins tsis parallel thiab thaum uas tig mus, thiab lawv raug hu ua triplets. Lub teeb uas lawv tso tawm yog qhov hu ua Phosphorescence.
Thaum lub xaim hluav taws xob hauv lub xeev txoj kev xa rov qab los ntawm qhov excimer siab zog mus rau lub xeev uas tsis muaj zog, nws lub zog yuav raug nyob rau hauv daim ntawv ntawm Lub Nruab Nrab Tso Los yog Tshav Kub Heev. Cov duab photon yuav siv los ua ib qho khoom ua haujlwm. Txawm li cas los xij, qhov triplet phosphorescence tsis tuaj yeem tau cai tom chav tsev sov nyob hauv cov khoom siv organic fluorescent, li ntawd, theoretical txwv ntawm qhov kev ua haujlwm ntawm PM-OLED tsuas yog 25% xwb.
Cov ntsiab lus ntawm PM-OLED lub teeb emission yog siv lub zog sib txawv ntawm cov khoom siv hloov lub zog tso tawm rau hauv photons, yog li peb muaj peev xwm xaiv cov khoom tsim nyog raws li lub teeb emitting txheej los yog tshaj tawm lub dye nyob rau hauv lub teeb emitting txheej kom tau lub teeb xim peb xav tau. Tsis tas li ntawd, qhov sib xyaw ua ke ntawm cov electrons thiab qhov yog feem ntau nyob rau hauv kaum tawm ntawm nanoseconds (ns), yog li qhov lus teb ntawm PM-OLEDs yog ceev heev.
PS: Cov qauv qub ntawm PM-OLED. Ib tug raug PM-OLED yog tsim los ntawm cov iav substrate, indium tin oxide (ATO) anode, organic organic emitting txheej (Emitting Material Txheej), ib lub cathode (Cathode), thiab cov zoo li, nyob rau hauv ITIN qhov nyias thiab pob organic lub teeb-emitting txheej yog sandwiched nrog ib tug hlau cathode zoo li ib tug nyuaj. Thaum qhov (qhov) txhaj rau hauv anode thiab electrons ntawm cathode (electron) raug ua ke nyob rau hauv organic lub teeb-emitting txheej, cov khoom siv organic yog siab ua kom emit teeb.
Tam sim no, ntau txheej txheem PM-OLED qauv nrog zoo efficiency luminous thiab nquag siv, ntxiv rau lub iav substrate, yin thiab yaj electrodes thiab organic lub teeb-emitting txheej, lub qhov kev txhaj tshuaj (HIL) thiab ib qhov kev thauj kab tshooj yog tseem yuav tsum tau xa. Qhov Hole Transport Layer (HTL), Electron Transport Layer (ETL), Electron Inject Layer (EIL), thiab lwm yam., Thiab ib txheej insulating yog yuav tsum tau ntawm txhua tus txheej txheem thiab cov electrode, yog li cov cua txias (Evaporate) yog ib qib high school thiab cov txheej txheem ntau lawm kuj nyuab heev.
Txij li thaum cov ntaub ntawv siv tshuaj thiab cov hlau ua rau cov pa oxygen thiab noo noo, tom qab ua tiav lawm, lawv yuav tsum muaj kev tiv thaiv los ntawm kev haus. Txawm hais tias PM-OLED xav tau los ntawm ntau cov yeeb yam organic nyias, qhov thickness ntawm cov organic thin film txheej yog li 1,000 txog 1,500? (0.10 rau 0.15 um), thiab tag nrho cov thickness ntawm tag nrho cov duab vaj huam sib luag (Vaj Huam Sib) yog tsawg dua 200 μm tom qab lub pob uas ntim nrog desiccant. (2mm), nrog kom zoo dua ntawm thinness.
Nyob rau hauv lub neej yav tom ntej, hloov LED nrog OLED sab hauv teeb pom kev zoo yog ib yam tseem ceeb hauv keeb kwm, thiab lub ncuav mog qab zib no yuav muaj ntau lub tuam txhab ua ntu.
