Qhov tseem ceeb ntawm LED zaub screen aging kev ntsuam xyuas yog qhov tseem ceeb hauv cov hauv qab no:
I. Tiv thaiv kom tsis txhob ntxov ntxov thiab ua kom cov khoom zoo
Nyob rau theem pib siv, LED zaub yuav ntsib teeb meem xws li lub teeb dim, flickering, ua haujlwm tsis zoo, thiab teeb pom kev sib cuam tshuam. Cov teeb meem no feem ntau tshwm sim los ntawm qhov tsis xws luag hauv cov khoom lossis kev tsim khoom tsis zoo. Kev ntsuam xyuas kev laus tuaj yeem nthuav tawm thiab tshem tawm cov kev phom sij zais cia ua ntej, zam kev ua tsis tiav batch tom qab xa khoom. Piv txwv li, ib pawg ntawm cov lus qhia nrog 5% tsis ua hauj lwm tus nqi ua ntej kev ntsuam xyuas kev laus tuaj yeem pom nws qhov tsis ua hauj lwm poob qis dua 0.2% tom qab 48 teev ntawm kev laus video.
Kev ntsuam xyuas kev laus yog cov txheej txheem tseem ceeb hauv theem kev tshuaj xyuas ntau lawm, ncaj qha txiav txim siab seb cov khoom puas tuaj yeem dhau qhov kev lees paub zaum kawg. Cov ntaub ntawv qhia tau hais tias cov lus qhia uas tsis tau kuaj xyuas kev laus nruj heev muaj kev lag luam rov qab los ntawm 3-7 npaug ntau dua li cov uas tau sim.

II. Txhim kho kev ua haujlwm ruaj khov thiab txuas ntxiv Lifespan
Raws li lub dab da dej nkhaus txoj kev xav, qhov tsis ua hauj lwm tus nqi ntawm cov khoom siv hluav taws xob nthuav tawm peb tus yam ntxwv - theem: "thaum ntxov tsis ua hauj lwm - lub sij hawm tsis ua hauj lwm tsis zoo - hnav- lub sij hawm tsis ua hauj lwm." Cov kev ntsuam xyuas kev laus simulate ntev- lub sijhawm siv cov xwm txheej, tso cai rau cov khoom lag luam sai dhau los ntawm lub sijhawm tsis ua haujlwm thaum ntxov thiab nkag mus rau lub sijhawm tsis ua haujlwm nrog qhov qis tshaj plaws. Tom qab kev sim, cov khoom lag luam tuaj yeem txhim kho los ntawm 10% -15%, thiab lub teeb tawg qeeb qeeb los ntawm ntau dua 30%.
Kev laus tsis tu ncua tam sim no ua tau raws li cov yam ntxwv ntawm LED tam sim no kev ua haujlwm, zam kev puas tsuaj los ntawm kev hloov pauv tam sim no thaum lub sij hawm qhov hluav taws xob tas li. Cov kev sim qhia tau hais tias cov hnub nyoog qis dua qhov tam sim no rau 48 teev muaj lub neej ntev 2000-5000 teev ntev dua li cov hnub nyoog qis dua qhov hluav taws xob tas li.
III. Txhim kho cov txheej txheem xeem kom ua tiav kev soj ntsuam
Theem -Raws li Kev Ntsuas System:
Dawb Lub Teeb Laus (4 teev): Cov ntxaij vab tshaus nrawm nrawm rau cov teeb meem luminescence yooj yim.
Kev laus yees duab (48 teev):** Txheeb xyuas cov duab dynamic.
Monochrome/Grayscale Gradient Test (Ntau dua lossis sib npaug rau 24 teev): Kev ntsuam xyuas xim xim sib xws.
Text Effect Test (Ntau dua lossis sib npaug li 24 teev):** Ntsuas ntug ntse thiab tiv thaiv- muaj peev xwm cuam tshuam.
Key Parameter Control: ** Kev tshuaj ntsuam dawb yuav tsum kav ntev li 24 teev, tsom rau kev saib xyuas cov teeb pom kev zoo.
Cov neeg ua haujlwm tshwj xeeb yuav tsum tau muaj thoob plaws hauv cov txheej txheem kev sim, kaw qhov ntsuas xws li ntsuas kub thiab tam sim no txhua 2 teev.
Kev kaw tam sim thaum kuaj pom qhov txawv txav; lub sij hawm qhov chaw txhaum yuav tsum tau tswj tsis pub dhau 30 feeb.
IV. Scientific Aging Methods kom tau txais qhov sib npaug ntawm qhov zoo thiab tus nqi
Tsis tu ncua Aging Advantages:
Tam sim no qhov tseeb yog tswj nyob rau hauv ± 1%, tsis txhob overcurrent puas.
tuaj yeem ua ke nrog kev ntsuas qhov ntsuas hluav taws xob dhau, ua kom muaj qhov tsis xws luag tshwm sim los ntawm luv luv - ncua sij hawm siab tam sim no (1.5 npaug ntawm tus nqi).
Piv nrog rau qhov tsis tu ncua voltage aging, qhov txhaum nrhiav tus nqi siab dua. Nce 40%
Tus nqi -Kev Tshawb Fawb Cov txiaj ntsig:
Txawm hais tias ib qho kev kuaj kev laus siv kwv yees li 0.5 kWh / sq.
Los ntawm kev txheeb xyuas cov teeb meem LEDs, tag nrho cov tshuaj ntsuam cov txiaj ntsig tuaj yeem nce los ntawm 85% mus rau 98%.
V. Kev lag luam daim ntawv thov tus nqi
Hauv siab - cov xwm txheej muaj kev ntseeg siab xws li cov ntxaij vab tshaus xauj thiab cov ntxaij vab tshaus theem, kev kuaj kev laus yog ib qho yuav tsum tau ua.
Vim lawv cov pixel ceev, me me -pitch displays yuav tsum dhau 72 teev ntawm kev laus tsis tu ncua kom ntseeg tau tias tsis muaj LEDs tuag.
Cov khoom tsim tshwj xeeb xws li iav cov ntxaij vab tshaus yuav tsum muaj kev co kev laus ntxiv los simulate qhov cuam tshuam ntawm kev thauj mus los.
Cov lus pom zoo rau kev siv:
Tsim kom muaj cov txheej txheem kev laus laus: 48 teev rau cov khoom lag luam, 72 teev rau siab - cov khoom kawg.
Txais yuav cov txheej txheem kev laus ntse: Tiag -Lub sijhawm saib xyuas qhov kub thiab txias qhov nkhaus thiab tsis siv neeg ceeb toom tsis zoo.
Txhim kho cov ntaub ntawv traceability: Sau cov kev laus ntawm txhua qhov screen thiab tsim kom muaj cov ntaub ntawv zoo.
Los ntawm kev ntsuam xyuas kev laus, LED cov khoom lag luam tuaj yeem tswj cov khoom lag luam tsis ua haujlwm qis dua 0.1%, txhim kho lub npe nrov npe.
