Ib, Qhov Sib txawv ntawm Cov Ntsiab Cai thiab Cov Ntsiab Cai
1. Backlight system tsim
Muaj qib LCDs siv lub teeb ci siab LED backlighting lossis dav kub CCFL (txias cathode fluorescent teeb) teeb pom kev zoo rau qhov chaw huab cua. Piv txwv li, nyob rau hauv lub oilfield xyuas qhov system, cov kev lag luam tshuaj ntsuam yuav tsum tau ua hauj lwm ruaj khov nyob rau hauv ib tug dav kub ntau yam ntawm -40℃mus rau 85℃. Nws lub teeb nraub qaum yog tsim los nrog cov ntim tshwj xeeb gel thiab hlau ncej cua sov kom ntseeg tau tias qis- kub pib- nce thiab siab - qhov kub thiab txias. Txawm li cas los xij, cov neeg siv khoom qib LCDs (xws li smartphones thiab TVs) feem ntau siv LED backlighting zoo tib yam hauv kev nrhiav kev slimness thiab nqi. Kev khiav hauj lwm kub yog feem ntau tsuas yog 0℃mus rau 40 degree, thiab lawv tsis muaj plua plav pov thawj thiab cov qauv tsis muaj dej.
2. Tsav Circuit Court thiab interface
Industrial grade products integrate industrial grade interfaces such as CAN bus, RS-485, PoE (Power over Ethernet) to meet industrial automation needs, supporting long-distance signal transmission (>20 meters) thiab tiv thaiv electromagnetic cuam tshuam (EMI) tsim. Piv txwv li, cov ntxaij vab tshaus muaj siv nyob rau hauv nuclear fais fab nroj tsuag tswj consoles yuav tsum xeem dhau MIL-STD-810G tub rog qauv kuaj, nrog 20G cuam tshuam tsis kam thiab 5-500Hz kev co kuj. Cov neeg siv khoom qib LCDs feem ntau yog siv cov khoom siv hluav taws xob sib cuam tshuam xws li HDMI thiab USB-C, tsis muaj cov khoom siv hluav taws xob rov qab tsim thiab cov khoom siv hluav taws xob dav dav (9-36V) muaj peev xwm.
3. Kov tshuab
Muaj qib kov cov ntxaij vab tshaus txhawb nqa cov hnab looj tes ua haujlwm, ntub dej, thiab cov tshuaj tiv thaiv corrosion resistant coatings, ua rau lawv tsim nyog rau cov xwm txheej xws li kev ua zaub mov thiab tshuaj engineering. Piv txwv li, lub vijtsam kov hauv qhov tawg-cov ntaub ntawv pov thawj rhiav siv infrared kov tshuab, uas tuaj yeem nkag mus rau 0.5mm tuab tiv thaiv iav, thaum cov neeg siv khoom qib capacitive npo tsuas yog txhawb nqa yooj yim kov thiab muaj kev cuam tshuam rau ib puag ncig.
2, Environmental Adaptability: Hloov los ntawm Laboratories mus rau Extreme Scenario
1. Kev kam rau siab kub
Muaj qib LCD ua tiav kev ua haujlwm kub kub los ntawm kev hloov khoom dua tshiab:
Low temperature start-up: Using a special liquid crystal formula (such as ultra-high resistivity liquid crystal, ρ>10 ¹Ω· cm), cov xau tam sim no raug txo kom qis dua 0.1 μ A kom ntseeg tau tias cov zaub ib txwm nyob ntawm -40℃ib puag ncig.
Kub kub dissipation: Kev sib xyaw ntawm cov hlau ncej thiab graphene tshav kub dissipation zaj duab xis ua rau muaj cov ntxaij vab tshaus ua haujlwm tsis tu ncua rau ntau tshaj 100000 teev ntawm qhov kub ntawm 85 degree, thaum cov neeg siv khoom lag luam muaj lub neej tsawg dua 10000 teev ntawm qhov kub no.
2. Kev tiv thaiv qib
Cov khoom lag luam qib tau dhau IP67 / IP69K daim ntawv pov thawj thiab tuaj yeem tiv taus siab - rab phom dej ntws tawm thiab chav nkag, haum rau sab nraum zoov digital signage, nkoj navigation thiab lwm yam xwm txheej. Piv txwv li, lub vijtsam tswj ntawm lub thawv chaw nres nkoj crane yuav tsum tau siv nyob rau hauv ib puag ncig ntsev tsuag rau lub sijhawm ntev, thiab nws qhov chaw tiv thaiv -corrosion txheej tuaj yeem tiv taus chloride ion yaig rau ntau tshaj 10 xyoo. Cov neeg siv khoom qib LCDs tsuas yog muaj kev tiv thaiv IP20, uas tuaj yeem tiv thaiv cov plua plav nkag thiab tsis tuaj yeem tiv thaiv cov dej los yog kua dej.
3. Mechanical stability
Muaj qib LCDs tau dhau MIL-STD-810G tus qauv ntsuas thiab muaj 20G kev cuam tshuam thiab 5-500Hz kev co kuj, ua rau lawv tsim nyog rau kev vibration scenarios xws li cov khoom siv tub rog thiab kev tsheb ciav hlau. Piv txwv li, cov ntaub ntawv tshuaj ntsuam ntawm siab - tsheb ciav hlau ceev yuav tsum tau tiv thaiv kev vibrations thaum lub tsheb ciav hlau ua haujlwm. Nws cov qauv yog tsim los nrog tempered iav thiab tawg-pov thawj zaj duab xis, thiab nws cov kev cuam tshuam tsis kam yog ntau tshaj 5 npaug ntawm cov neeg siv khoom qib.
3, Customization muaj peev xwm: los ntawm standardization mus rau scenario raws li kev daws teeb meem
1. Zaub parameter customization
Industrial grade LCD supports deep customization of parameters such as brightness (adjustable from 300-2000nit), contrast ratio (above 1500:1), color gamut (covering 90% DCI-P3), etc. For example, medical operating room monitors require high brightness (>1000nit) and high contrast (>2000: 1) kom pom cov hlab ntsha thiab cov ntaub so ntswg kom meej meej; Txawm li cas los xij, cov khoom siv qib siab feem ntau muaj qhov ci ntsa iab ntawm 200-400nit thiab xim gamut npog 72% NTSC, uas nyuaj rau kev ua kom tau raws li cov kev xav tau.
2. Kev tsim kho tshiab ntawm qhov loj thiab daim ntawv
Cov khoom lag luam qib tau tawg los ntawm cov kev txwv loj ib txwm muaj, txhawb nqa nqaim ciam teb (ciam dav dav<2mm), irregular cutting (circular, curved), and splicing display (supporting seamless splicing of up to 100 screens). For example, the smart city traffic command center adopts a 46 inch 5 × 5 splicing screen to achieve 360 ° panoramic monitoring; Consumer grade LCDs mainly rely on standardized sizes (such as 27 inches and 55 inches) and lack flexible customization capabilities.
3. Kev ua haujlwm ua ke
Muaj qib LCD tuaj yeem ua ke ntau lub sensors (xws li photosensitive, kub, thiab av noo sensors), ntse tswj systems (xws li Android / Linux embedded systems), thiab tej thaj chaw deb tswj functions (batch screen tswj los ntawm RS-232 / network). Piv txwv li, cov khoom siv hluav taws xob txias txias yuav tsum tau saib xyuas qhov kub thiab txias hauv lub sijhawm thiab xa cov ntaub ntawv, thiab lawv cov ntxaij vab tshaus tso saib ua ke nrog IoT modules thiab lub tswb nrov; Cov khoom siv qib siab tsuas yog muaj cov haujlwm yooj yim tso saib thiab tsis muaj scalability.
4, Tus nqi tsim nyog thiab kev tswj hwm lub neej
1. Tus nqi pib thiab lub sijhawm ntev - tus nqi
Chav tsev nqi ntawm qib industrial LCD yog 3-5 npaug ntawm cov khoom siv qib siab, tab sis nws lub neej voj voog (8-}10 xyoo) yog ntau dua ob npaug ntawm cov khoom siv qib (3-5 xyoos). Piv txwv li, muaj cov ntxaij vab tshaus siv cov khoom zoo xws li Nichia LED los ntawm Nyiv thiab Schott iav los ntawm lub teb chaws Yelemees. Txawm hais tias tus nqi pib yog siab, lub sij hawm nruab nrab ntawm kev ua tsis tiav (MTBF) tuaj yeem ncav cuag 100000 teev, uas tuaj yeem txo cov nqi tu; Cov khoom siv qib siab siv cov khoom siv nruab nrab nrog MTBF tsuas yog 30000 teev thiab yuav tsum tau hloov ntau zaus.
2. Supply saw stability
Cov khoom lag luam qib LCD muab lub voj voog khoom siv ntau tshaj 10 xyoo thiab txhawb kev txhim kho cov kev daws teeb meem (xws li kev hloov kho software kom haum rau cov khoom siv tshiab tom qab cov qauv qub raug txiav tawm) kom ntseeg tau ntev - lub sijhawm muaj cov khoom siv rau cov neeg siv khoom. Cov khoom siv qib siab tau hloov kho thiab hloov pauv sai, piv txwv li, cov ntxaij vab tshaus xov tooj ntawm tes raug txiav tawm qhov nruab nrab txhua 2 xyoos, ua rau muaj teeb meem hauv kev tu cov cuab yeej.
3. Kev pab cuam tom qab muag
Cov tuam txhab qib kev lag luam muab 3- xyoo warranty thiab kev pab cuam lub neej. Piv txwv li, Advantech cov khoom siv tshuaj ntsuam xyuas txhawb kev lees paub thoob ntiaj teb thiab 48 teev cov lus teb sai; Lub sijhawm lav rau cov khoom siv qib siab feem ntau tsuas yog ib xyoos xwb, thiab kev pab cuam tom qab muag kev pabcuam raug txwv.
5, Kev lag luam daim ntawv thov scenarios thiab xaiv cov lus qhia
1. Muaj automation
Thaum xaiv ib qho kev lag luam qib LCD, kev saib xyuas yuav tsum tau them rau:
Dav kub tsim: Ua kom ruaj khov ua haujlwm ntawm -40℃txog 85 degree;
Kev tiv thaiv kev vibration: tau ntawv pov thawj los ntawm MIL-STD-810G;
