1, Kev ua haujlwm hauv paus ntsiab lus: Qhov sib txawv tseem ceeb ntawm cov zaub tsis zoo thiab lub teeb ci tawm
LCD thev naus laus zis yog ua raws li cov electro-optic nyhuv ntawm cov kua siv lead ua kua molecules thiab yuav tsum muaj txheej backlight (LED lossis CCFL) los muab lub teeb ci. Cov kua siv lead ua kua txheej tswj lub teeb xa hluav taws xob los ntawm qhov hluav taws xob thiab ua ke nrog cov xim lim kom ua tiav cov duab sib xyaw ntawm cov xim liab, ntsuab, thiab xiav. Nws cov ntsiab lus yog "lub teeb valve" qauv, uas tso siab rau cov teeb pom kev sab nraud los hloov lub teeb thiab belongs rau cov cuab yeej siv hluav taws xob passive.
OLED thev naus laus zis siv lub hauv paus ntsiab lus ntawm tus kheej luminescence ntawm cov ntaub ntawv organic semiconductor, qhov twg txhua pixel yog nws tus kheej tsim los ntawm cov khoom siv liab, ntsuab, thiab xiav organic. Tom qab tau siv lub tshuab hluav taws xob, nws ncaj qha tawm lub teeb yam tsis tas yuav tsum muaj txheej txheej backlight lossis kua siv lead ua txheej. Cov cuab yeej ua haujlwm luminescent no ua rau nws cov qauv yooj yim dua thiab nws cov tuab tuaj yeem ua rau qis dua 1 hli, muab qhov ua tau rau cov duab hloov tau.
2, Zaub kev ua tau zoo: kev sib tw ntawm qhov sib piv, xim, thiab cov lus teb ceev
sib piv
OLED, nrog nws cov pixel theem tswj lub teeb muaj peev xwm tswj tau, tuaj yeem tua cov pixels thaum pom cov xim dub, ua tiav qhov kev sib piv tsis kawg (∞: 1) thiab cov duab sib sib zog nqus thiab pob tshab. Txawm li cas los xij, vim tias tsis muaj peev xwm tua lub teeb rov qab, LCD tshwm grey xim dub, thiab qhov sib piv feem ntau yog nyob nruab nrab ntawm 1000: 1 thiab 3000: 1. Txawm hais tias siab -kawg quantum dot LCD tuaj yeem txhim kho rau 5000: 1, nws tseem qis dua OLED.
Xim kev ua haujlwm
OLED xim gamut kev pab cuam feem ntau yog dav dua (xws li DCI-P3 xim gamut ncav cuag tshaj 98%), nrog cov xim ci thiab saturated, haum rau scenes uas xav tau kev ncaj ncees siab. Cov xim ua haujlwm ntawm LCD nyob ntawm qhov zoo ntawm lub teeb. Cov xim gamut ntawm cov qauv zoo tib yam yog kwv yees li 72% NTSC, thaum cov qauv siab -kawg tuaj yeem txhim kho mus rau 100% NTSC los ntawm quantum dot technology, tab sis qib dub tseem qis dua OLED.
teb ceev
OLED muaj lub sijhawm teb ntawm microseconds thiab yuav luag tsis muaj dab tsi, ua rau nws haum rau siab -cov duab nrawm nrawm (xws li kev soj ntsuam cov neeg hlau ua haujlwm). Lub sij hawm teb ntawm LCD yog nyob rau hauv milliseconds (feem ntau yog 5-20ms), thiab qib gaming LCD yuav luv luv mus rau 1ms los ntawm optimization, tab sis tseem muaj kev pheej hmoo ntawm ghosting.
3, Cov yam ntxwv ntawm kev siv hluav taws xob: cov tswv yim sib txawv rau lub zog raws li lub zog-txuag
Tsaus xim duab siv zog
Thaum OLED qhia cov xim dub, cov pixels raug kaw tag, thiab lub zog siv zero, ua rau nws haum rau hmo ntuj lossis tsaus nti interface scenes. Piv txwv li, thaum lub ntsuas ntsuas ntse nyob rau hauv hom standby, nws tsuas yog ua kom lub sijhawm tso saib thaj chaw, thiab OLED lub zog siv tau raug txo kom qis dua 0.1mW / cm².
Kev siv zog ntawm cov duab ci xim
LCD muaj lub zog siv hluav taws xob ruaj khov uas muaj txiaj ntsig zoo dua thaum pom cov duab dawb kiag li, vim tias lub teeb pom kev zoo ib txwm qhib thiab lub zog noj yog ywj siab ntawm cov duab cov ntsiab lus. Cov LCDs siab kawg tuaj yeem txo qis kev siv hluav taws xob hauv zos los ntawm cheeb tsam dimming thev naus laus zis (xws li Mini LED backlight), tab sis tag nrho kev siv hluav taws xob tseem siab dua OLED ci xim scenes.
Tsav voltage xav tau
LCD yuav tsum muaj 2-3V AC tsav hluav taws xob thiab yuav tsum zam cov khoom siv DC (tsis pub tshaj 100mV) txhawm rau tiv thaiv cov kua siv lead ua kua electrolysis. OLED muaj lub zog tsav qis dua (3.3V DC txaus rau kev ua haujlwm), tab sis kev tswj hwm tam sim no yuav tsum tau ua kom tsis txhob muaj qhov screen hlawv.
4, Lifespan thiab Reliability: Kev Ntsuas Lub Sij Hawm Ntev hauv Kev Lag Luam
Lifespan mechanism
Lub neej ntev ntawm lub LCD nyob ntawm qhov txo qis ntawm lub teeb pom kev zoo (feem ntau yog 50000 txog 100000 teev), thiab tsis muaj kev pheej hmoo ntawm kev tshuaj ntsuam hlawv -hauv, ua rau nws tsim nyog rau kev nthuav tawm cov ntsiab lus zoo li qub rau lub sijhawm ntev (xws li cov khoom siv teeb pom kev zoo). Lub neej ntev ntawm OLED yog txwv los ntawm kev laus ntawm cov khoom siv organic (kwv yees li 30000 txog 50000 teev), thiab ntev - lub sijhawm tso saib cov duab ruaj khov (xws li cov xwm txheej tuav) tuaj yeem ua rau pixel seem (kub-in), uas yuav tsum tau txo qis los ntawm cov tswv yim xws li pixel hloov chaw thiab txo qhov ci.
ib puag ncig adaptability
LCD yog tsim los nrog ntau qhov kub thiab txias (-40℃rau +85} degree) thiab cov qauv tsis muaj plua plav thiab dej tsis zoo (xws li IP65 ntsuas) kom hloov mus rau qhov chaw muaj kev lag luam loj. Txawm hais tias OLED muaj seismic kev ua tau zoo, qhov degradation ntawm cov ntaub ntawv organic nrawm nrawm hauv qhov kub thiab txias, thiab kev ntseeg siab yuav tsum tau ua kom zoo dua los ntawm kev tsim hluav taws xob.
5, Tus Nqi thiab Kev Tsim Khoom: Qhov Kev Ua Si ntawm Ncua Sijhawm thiab Cov Txheej Txheem Txheej Txheem
Khoom siv
LCD kev lag luam saw yog cov paub tab, thiab cov khoom xws li iav substrates, cov ntaub ntawv siv lead ua kua, thiab cov khoom siv hluav taws xob muaj cov nqi qis, ua rau lawv siv dav hauv nruab nrab mus rau qis kawg cov twj paj nruag. OLED yuav tsum tau siv cov organic teeb pom kev zoo- emitting cov ntaub ntawv thiab precision vapor deposition khoom, nrog rau cov nqi siab (tshwj xeeb tshaj yog rau loj - loj panels). Tam sim no, nws yog tsuas yog siv nyob rau hauv high -end industrial cov cuab yeej xws li aviation instruments thiab kho mob.
Kev tsim khoom nyuaj
LCD manufacturing process is stable, with a high yield rate (>95%), haum rau loj- teev ntau lawm. OLED yuav tsum tso cov ntaub ntawv organic hauv lub tshuab nqus tsev los ntawm lub tshuab vapor deposition, uas yog cov txheej txheem nyuaj (xws li kev tswj pixel kev sib raug zoo ntawm qib micrometer) thiab muaj tus nqi qis (kwv yees li 70% -80%), ua rau cov nqi tag nrho.
6, Muaj daim ntawv thov scenarios: meej txuam ntawm cov kev xav tau sib txawv
LCD Muaj Scenarios
Lub sij hawm ntev static zaub: xws li cov cuab yeej ua haujlwm raws li txoj cai qhia teeb thiab parameter zaub panels.
