1, Environmental kam rau ua: muaj peev xwm ciaj sia nyob rau hauv ib puag ncig huab
Ib qho ntawm cov hom phiaj tsim qauv tseem ceeb ntawm kev lag luam LCDs yog hloov mus rau qhov chaw huab cua. Nws qhov kub ua haujlwm feem ntau suav nrog -40℃txog 85℃, thiab qee cov qauv txawm txhawb nqa huab cua ntawm -50℃txog 100℃. Piv txwv li, nyob rau hauv oilfield xyuas systems, industrial LCDs yuav tsum tau pib ntawm ib tug tsawg kub ntawm -40℃thiab tseem ua hauj lwm nyob rau hauv ib tug kub qhov chaw ntawm 85 degree; Nyob rau ntawm qhov chaw txias txias logistics davhlau ya nyob twg, lub vijtsam zaub yuav tsum tswj kom pom tseeb hauv qhov chaw khov ntawm -25 degree. Tsis tas li ntawd, kev lag luam LCDs feem ntau txais yuav IP67 / IP69K kev tiv thaiv qib, uas tuaj yeem tiv thaiv plua plav los ntawm kev nkag mus thiab tiv taus cov phom dej siab lossis chav dav hlau ntxuav, tsim nyog rau cov chaw muaj kev tiv thaiv zoo xws li cov chaw ua haujlwm tshuaj lom neeg thiab cov chaw ua haujlwm hauv hiav txwv.
Hauv qhov sib piv, cov neeg siv khoom qib LCDs yog tsim los rau sab hauv tsev qhov kub thiab txias ib puag ncig, nrog rau kev ua haujlwm kub ntawm 0℃txog 40 degree. Nws qib kev tiv thaiv feem ntau yog IP20 (tsuas yog cov plua plav pov thawj), thiab qee cov qauv siab -kawg tuaj yeem ncav cuag IP54 (piv txwv li thiab tsis muaj dej), tab sis nws tsis tuaj yeem tiv nrog cov dej nag sab nraum zoov, plua plav lossis tib neeg txaws. Piv txwv li, lub vijtsam xov tooj ntawm tes yuav luv luv vim muaj dej nkag hauv cua daj cua dub, thaum lub TV hauv tsev yog qhov yooj yim rau kev puas tsuaj vim yog qhov dej nyob hauv qhov chaw ntub dej.
2, Kev ruaj ntseg thiab kev ntseeg siab: lav kev ua haujlwm tsis cuam tshuam 24/7
Cov kev cai ruaj khov rau cov LCDs muaj ntau dua li cov khoom siv rau cov neeg siv khoom qib. Nws lub neej kev tsim qauv feem ntau yog 80000 txog 100000 xuab moos, nrog qee cov qauv mus txog 150000 teev, txhawb xyoo- ua haujlwm ib puag ncig. Piv txwv li, lub tshav dav hlau ya davhlau cov ntaub ntawv tshuaj ntsuam yuav tsum tsis tu ncua tso saib lub davhlau hloov tshiab 24 teev ib hnub twg. Yog tias muaj kev ua haujlwm tsis zoo, nws yuav ua rau tsis meej pem hauv cov ntaub ntawv neeg caij tsheb; Lub vaj huam sib luag tso saib ntawm lub tshuab hluav taws xob nuclear yuav tsum ua haujlwm ruaj khov nyob rau hauv ib puag ncig hluav taws xob ntev, thiab txhua qhov flickering lossis khov yuav ua rau muaj kev nyab xeeb. Txhawm rau ua kom tau raws li qhov xav tau, cov LCDs tau txais kev tsim hluav taws xob tsis tu ncua (txhawb 9-36V dav voltage input), tub rog qib connectors (xws li MIL-STD-810G ntawv pov thawj), thiab tiv thaiv electromagnetic cuam tshuam (EMI) shielding thev naus laus zis los xyuas kom ruaj khov ua haujlwm hauv kev vibration muaj zog thiab siab electromagnetic cuam tshuam ib puag ncig.
Tus tsim lub neej ntawm cov neeg siv khoom qib LCDs feem ntau yog nyob nruab nrab ntawm 30000 txog 50000 teev, nrog rau qhov ntsuas ntawm 8 teev ntawm kev siv ib hnub. Piv txwv li, yog tias lub TV hauv tsev ua haujlwm tsis tu ncua rau ntau tshaj 12 teev, lub backlight lub neej yuav luv luv; Cov ntxaij vab tshaus ntawm lub xov tooj smartphone yog qhov yooj yim rau kev tshuaj ntsuam hlawv- nyob rau hauv ntev - lub sij hawm siab brightness zaub. Tsis tas li ntawd, txhawm rau txo cov nqi, cov neeg siv khoom siv feem ntau siv cov plhaub yas thiab cov khoom tsis muaj kev lag luam. Lawv qhov cuam tshuam tsis kam thiab kev laus ua haujlwm tsis muaj zog, thiab nws nyuaj rau ua kom tau raws li qhov xav tau nruj ntawm kev lag luam scenarios.
3, Zaub kev ua tau zoo: readability thiab xim raug nyob rau hauv lub teeb muaj zog
Cov zaub kev ua tau zoo tsim ntawm kev lag luam LCD yog nyob ib ncig ntawm kev ua haujlwm. Nws qhov ci ci yog feem ntau 500-2500 nits, thiab qee cov qauv sab nraum zoov tuaj yeem ncav cuag ntau dua 3000 nits, uas tuaj yeem tiv thaiv tshav ntuj ncaj qha. Piv txwv li, lub vijtsam xov xwm kev loj yuav tsum tau tso saib cov ntaub ntawv ntawm txoj kev kom meej nyob rau hauv lub teeb muaj zog thaum tav su. Yog tias qhov ci ci tsis txaus, nws yuav ua rau tus neeg tsav tsheb tsis tuaj yeem nyeem nws; Cov tshuab tshaj tawm sab nraum zoov yuav tsum tau cia li txo qhov ci thaum tsaus ntuj lossis hmo ntuj kom txuag tau lub zog thaum tswj cov xim saturation. Txhawm rau txhim kho kev nyeem ntawv ntawm lub teeb muaj zog, cov LCDs feem ntau siv los tiv thaiv glare (AG) txheej thiab tiv thaiv kev cuam tshuam (AR) thev naus laus zis los txo qhov kev xav ntawm lub teeb pom kev zoo thiab xyuas kom meej cov duab.
Qhov ci ntawm cov neeg siv khoom qib LCDs feem ntau yog nyob nruab nrab ntawm 200-400 nits, ua kom zoo rau kev siv sab hauv tsev. Piv txwv li, lub khoos phis tawj saib yuav muab cov duab meej meej nyob rau hauv ib txwm teeb pom kev zoo, tab sis tej zaum yuav tsis nyeem tau nyob rau sab nraum zoov vim qhov ci tsis txaus; Txawm hais tias cov ntxaij vab tshaus smartphone txhawb hom kev ci ntsa iab, ntev - siv sijhawm tuaj yeem ua rau lub roj teeb poob sai. Tsis tas li ntawd, cov neeg siv khoom qib muab qhov tseem ceeb rau kev qhia xim, feem ntau siv cov xim dav dav (xws li 90% DCI-P3) thiab qhov sib txawv siab (xws li 1000: 1) thev naus laus zis los txhim kho kev pom kev pom, tab sis cov yam ntxwv no tsis tsim nyog nyob rau hauv kev lag luam scenarios.
4, Interface thiab Scalability: Technical Support rau Customized Requirements
Lub interface tsim ntawm industrial LCD yog coj los ntawm compatibility thiab scalability. Nws cov qauv interfaces suav nrog HDMI, DP, RS-232, USB 3.0, CAN tsheb npav, PoE (Power dhau Ethernet), thiab muaj Ethernet, uas tuaj yeem txuas cov khoom siv xws li PLCs, sensors, koob yees duab, thiab lwm yam kom ua tiav cov ntaub ntawv sib pauv thiab cov chaw taws teeb tswj. Piv txwv li, nyob rau hauv kev txawj ntse tsim kev cob qhia, muaj LCDs yuav tsum tau sib txuas lus nrog CNC tshuab cuab yeej los ntawm RS-485 interfaces los tso saib ua tsis tau nyob rau hauv lub sij hawm; Hauv cov cuab yeej siv kho mob, lub vijtsam zaub yuav tsum tau txais cov duab teeb liab ntawm lub ntsuas ultrasonic los ntawm DVI interface thiab txhawb kev ua haujlwm kov los kho qhov ntsuas ntsuas. Tsis tas li ntawd, muaj LCD txhawb nqa ntau lub vijtsam splicing, cais npo zaub, thiab kev tswj chaw taws teeb, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov xwm txheej nyuaj.
Lub interface tsim ntawm cov neeg siv khoom qib LCD yog raws li cov hauv paus ntsiab lus ntawm kev yooj yim thiab universality. Nws cov qauv interfaces yog HDMI, USB-C, thiab 3.5mm audio interface, feem ntau yog siv los txuas cov khoos phis tawj, game consoles, lossis cov khoom siv streaming. Piv txwv li, lub TV hauv tsev tau txais cov teeb liab los ntawm lub teeb - sab saum toj lub thawv los ntawm HDMI interface, thaum lub xov tooj smartphone ua tiav kev them nyiaj thiab xa cov ntaub ntawv los ntawm USB -C interface. Txawm li cas los xij, cov khoom siv qib qis tsis muaj kev cuam tshuam qib kev lag luam xws li CAN tsheb npav PoE), tsis tuaj yeem txuas ncaj qha rau kev tswj hwm kev lag luam thiab tsis txhawb kev tsim kho tshwj xeeb.
5, Lub neej voj voog thiab tom qab- kev muag khoom: kev txiav txim siab nqi rau kev siv sijhawm ntev -
Kev tswj xyuas lub neej ntawm LCDs muaj nyob ib puag ncig ntev -cov khoom siv thiab kev sib raug zoo. Kev xaiv ntawm nws cov khoom ua raws li lub hauv paus ntsiab lus ntawm "lub neej ntev, muaj kev ntseeg siab", xws li kev siv qib kev lag luam LED backlight (lub neej Ntau dua lossis sib npaug li 100000 teev) thiab cov tub rog qib txuas (lub neej Ntau dua lossis sib npaug rau 50 xyoo). Tsis tas li ntawd, cov khoom lag luam LCD feem ntau muab lub voj voog ntawm ntau tshaj 10 xyoo, thiab txawm tias tus lej qauv raug txiav tawm, lwm cov qauv sib xws nrog "Form, Fit, Function" (FFF) yuav raug tso tawm kom ntseeg tau tias cov neeg siv khoom tuaj yeem hloov kho yam tsis muaj kev hloov kho. Piv txwv li, cov khoom lag luam xws li Advantech thiab Beckhoff cog lus tias yuav muab cov neeg siv khoom tsawg kawg 10 xyoo ntawm kev txhawb nqa khoom, txo cov nqi kho khoom.
Lub neej voj voog ntawm cov neeg siv khoom qib LCDs yog coj los ntawm kev ua lag luam iteration. Nws cov kev xaiv xaiv tsom mus rau kev ua kom zoo dua tus nqi, xws li siv nruab nrab -ntau LED backlighting (nrog lub neej ntev ntawm 30000 txog 50000 teev) thiab cov neeg siv khoom qib txuas (nrog rau lub neej ntawm 5-10 xyoo). Lub voj voog hloov tshiab rau cov khoom siv qib siab feem ntau yog 6-12 lub hlis, thiab tom qab tso tawm cov qauv tshiab, cov qauv qub yuav maj mam txiav. Piv txwv li, yog tias lub vijtsam ntawm lub xov tooj smartphone puas lawm, cov neeg siv yuav tsum tau yuav cov khoom qub lossis cov khoom siv thib peb, thiab kev sib raug zoo yuav raug txwv; Yog tias lub TV hauv tsev yuav tsum tau hloov kho nws cov cuab yeej tso saib (xws li hloov kho dua tshiab ntawm LCD rau OLED), tag nrho cov cuab yeej yuav tsum tau hloov, uas ua rau tus nqi siv ntau ntxiv.
