Ib, Technical hauv paus ntsiab lus: Lub hauv paus ntsiab lus ntawm passive lub teeb emission thiab teeb pom kev zoo
Lub hauv paus ntsiab lus ntawm LCD yog raws li cov yam ntxwv deflection ntawm cov kua siv lead ua kua molecules nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb, thiab cov duab yog tsim los ntawm kev tswj lub backlight kom nkag mus rau hauv cov kua siv lead ua kua txheej. Nws cov qauv tseem ceeb suav nrog cov iav substrate, cov kua siv lead ua kua, txheej electrode, polarizer, thiab lub teeb pom kev zoo. Vim qhov tseeb tias LCD nws tus kheej tsis tawm lub teeb, nws cov nyhuv tso saib yog nyob ntawm qhov ua tau zoo ntawm lub teeb pom kev zoo thiab kev cuam tshuam nrog lub teeb pom kev zoo.
Laboratory ib puag ncig:
Cov chaw soj nstuam feem ntau siv qhov ntsuas kub thiab av noo tas li, nrog lub teeb siv tsawg (kwv yees li 100-500 lux), thiab feem ntau yog tso siab rau cov teeb pom kev zoo. Nyob rau hauv cov xwm txheej no, cov txiaj ntsig ntawm LCD feem ntau yog nyob ntawm lub teeb ci ntsa iab thiab xim muaj peev xwm tsim tawm. Piv txwv li, LCDs hauv cov khoom siv kho mob yuav tsum ua kom tau raws li DICOM tus qauv thiab xyuas kom meej cov ntsiab lus hauv X-ray thiab CT duab los ntawm high-precision grayscale zaub (xws li 10 ntsis xim qhov tob); Lub LCD hauv cov cuab yeej tshawb fawb tshawb fawb xav tau los txhawb qhov dav xim gamut (xws li sRGB 100%) kom raug nthuav tawm cov ntaub ntawv tsom xam spectral.
Sab nraum zoov ib puag ncig:
Lub teeb ci sab nraum zoov tuaj yeem ncav cuag 6000-100000 lux (hnub ci thaum tav su), deb tshaj qhov ci ntawm LCD backlight (cov ntxaij vab tshaus sab hauv tsev yog li 300-500 nits). Nyob rau lub sijhawm no, ambient light forms reflections on the screen deg. Yog tias lub teeb ci ntsa iab tsis txaus, lub teeb pom kev zoo yuav npog cov ntsiab lus ntawm lub vijtsam, ua rau muaj qhov tshwm sim "dawb screen". Piv txwv li, lub drone chaw taws teeb tswj yuav tsum tau ua kom lub brightness mus rau 800-1000 nits nyob rau hauv lub teeb muaj zog kom pom lub davhlau tsis meej; Cov tshuab tshaj tawm sab nraum zoov xav tau lub teeb pom kev zoo siab ntawm 2000 nits lossis ntau dua, ua ke nrog Translucent thev naus laus zis los txhim kho cov nyhuv pom siv lub teeb pom kev zoo.
2, Environmental adaptability: ib qho kev sib tw los ntawm kev tswj kub thiab av noo mus rau kev tiv thaiv txhua yam
1. Qhov kub thiab txias: Cov kua siv lead ua theem hloov pauv thiab cov khoom siv hluav taws xob ruaj khov
Cov kua siv lead ua kua molecules ntawm LCD nyob twj ywm kua hauv qhov kub thiab txias (feem ntau yog -20℃txog 70 degree), thiab dhau ntawm qhov no, theem kev hloov pauv (crystallization lossis vaporization) tshwm sim, ua rau cov zaub tsis zoo.
Kev tswj qhov kub thiab txias yog nruj (xws li 20℃± 2℃), thiab LCD tuaj yeem ua haujlwm ruaj khov ntawm cov qauv kev lag luam (-} 30℃txog 85℃), tab sis hauv zos overheating yuav tsum raug zam (xws li kev ua haujlwm siab ntev ntev ua rau lub teeb pom kev zoo dua li qhov txwv).
Sab nraum zoov ib puag ncig: Yuav tsum tau tiv nrog huab cua kub (xws li Arctic kev tshawb fawb cov cuab yeej txhawb nqa -40℃qis kub, suab puam saib cov cuab yeej withstanding 60℃siab kub). Cov tshuaj muaj xws li:
Siv cov khoom siv ua kua kub kub (xws li TN thiab VA hom kua siv lead ua kua);
Integrated ntse kub tswj qhov system (xws li cov yeeb nkab cua sov dissipation, hluav taws xob cua sov zaj duab xis);
Optimize lub backlight tsav Circuit Court kom txo cov cua sov tsim.
2. Humidity thiab Corrosion: Sealing tsim thiab xaiv cov khoom siv
Cov av noo ib puag ncig yuav ua rau muaj qhov sib txawv hauv LCDs, ua rau luv luv Circuit Court lossis electrode corrosion.
Laboratory ib puag ncig: Cov av noo feem ntau yog tswj los ntawm 30% -70% RH, thiab LCD tuaj yeem ua tau raws li qhov yuav tsum tau muaj nrog cov qauv kaw lus.
Sab nraum zoov ib puag ncig: Nws yog ib qho tsim nyog los daws cov kab mob corrosive xws li los nag, daus, tshuaj tsuag ntsev, thiab lwm yam kev lag luam kev daws teeb meem suav nrog:
Peb cov ntaub ntawv pov thawj kev kho mob (dustproof, waterproof, anti{0}}corrosion): Sau cov qhov khoob hauv qhov sib khi, thiab lub plhaub tau txais kev tiv thaiv qib IP65;
Txheej txheej: Deposition ntawm AR (anti reflection) zaj duab xis thiab AF (anti ntiv tes) zaj duab xis rau txheej txheej ntawm iav substrate los txhim kho khawb tsis kam thiab hydrophobicity;
Cov khoom siv kho dua tshiab: Siv cov khoom siv corrosion- tiv taus xws li stainless hlau ncej thiab silicone sealing nplhaib.
3. Mechanical stress: Los tiv thaiv kev cuam tshuam thiab kev co tsim
Cov khoom siv sab nraum zoov feem ntau ntsib cov kev ntxhov siab xws li kev thauj mus los thiab kev cuam tshuam cua.
Laboratory ib puag ncig: Cov cuab yeej siv tau ruaj khov nrog kev ntxhov siab me me, thiab LCD tuaj yeem txais kev tsim qauv (xws li thickness<5mm).
Ib puag ncig sab nraum zoov: MIL-STD-810G yuav tsum muaj ntawv pov thawj tub rog, siv:
Reinforced iav (xws li Corning Gorilla Glass, uas ua rau muaj kev cuam tshuam los ntawm peb zaug);
Hlau ncej reinforcement (xws li aluminium alloy nruab nrab ncej);
Flexible Circuit Board (FPC) yog tsim los nqus lub zog vibration.
3, Daim ntawv thov scenario: Cov kev xav tau sib txawv los ntawm cov cuab yeej precision mus rau loj - teev kev tshaj tawm
1. Laboratory scenario: Siab precision thiab qis latency
Lub chaw soj ntsuam LCD yuav tsum ua kom tau raws li qhov siab - qhov yuav tsum tau muaj tseeb ntawm kev tshawb fawb thiab kev kho mob:
Cov duab kho mob: siv qib kev kho mob LCD (xws li EIZO RadiForce series), txhawb nqa 10 me ntsis greyscale zaub thiab DICOM Part 14 calibration kom paub meej qhov txhab;
Kev soj ntsuam kev tshawb fawb: Siv siab - LCD ceev (xws li 120Hz refresh npaum li cas) ua ke nrog kev sib cuam tshuam kov kom ua tiav - lub sijhawm cov ntaub ntawv pom (xws li kua dej dynamics simulation);
Tsawg latency yuav tsum tau: Los ntawm optimizing tus tsav tsheb IC thiab cov teeb liab kis tau tus mob txoj kev, lub sij hawm teb yuav luv luv mus rau hauv 5ms kom tsis txhob dynamic duab ghosting.
2. Sab nraum zoov scenes: siab brightness thiab ntev lifespan
Sab nraum zoov LCDs yuav tsum sib npaug visibility thiab durability:
Kev tshaj tawm tshuab: txais yuav LED backlight thiab hauv zos dimming tshuab, ua tiav qhov ci ntawm 2000 nits thiab qhov sib piv ntawm 10000: 1. Nyob rau tib lub sijhawm, lub teeb pom kev ntse ntse yuav kho qhov ci ntsa iab raws li lub teeb pom kev zoo, txo lub zog noj;
Cov paib tsheb: siv semi-reflective thiab semi transparent LCD, xav txog lub teeb pom kev zoo los txhim kho cov duab nyob rau hauv lub hnub ci ncaj qha, hloov mus rau backlight hom thaum hmo ntuj, txo hwj chim noj los ntawm 60%;
Kev tsim lub neej ntev: Los ntawm kev ua kom zoo dua lub neej ntev ntawm cov hlaws rov qab (xws li 100000 teev ntawm LED) thiab cov qauv cua sov, cov khoom siv sab nraum zoov tuaj yeem ua haujlwm tsis tu ncua rau ntau tshaj 5 xyoos yam tsis muaj kev saib xyuas.
