Ib, Lub hauv paus ntsiab lus ntawm Kev Sib Txuas Tshuab: Lub Cev Lub Cev ntawm Ntshiab Dub thiab Dawb
Qhov sib piv ntawm segmented LCD txhais tau tias yog qhov sib piv ntawm qhov ci ntawm qhov ci tshaj plaws (dawb) mus rau qhov tsaus ntuj tshaj plaws (dub) ntawm lub vijtsam, thiab nws cov qauv kev suav yog:
Contrast=qhov siab tshaj plaws (dawb) / qhov ci tsawg kawg nkaus (dub)
Piv txwv li, thaum lub teeb ci dawb yog 200 cd / m ² thiab qhov ci dub yog 0.5 cd / m ², qhov sib piv yog 400: 1; Yog tias qhov ci ntsa iab dub txo qis rau 0.1 cd / m ², qhov sib piv sib piv nce mus rau 2000: 1. Qhov sib txawv ntawm tus lej no ncaj qha txiav txim siab qhov ci ntsa iab ntawm qhov screen:
Qhov zoo ntawm qhov sib txawv siab: Dub yog tsaus, dawb yog purer, cov npoo yog ntse, tsis txhob pom qhov muag plooj tshwm sim los ntawm huab cua. Piv txwv li, hauv kev saib xyuas kev kho mob, qhov sib txawv siab (feem ntau ntau dua lossis sib npaug ntawm 1000: 1) ua kom cov neeg ua haujlwm kho mob tuaj yeem txheeb xyuas qhov hloov pauv me me hauv qhov tseem ceeb xws li lub plawv dhia thiab ntshav siab.
Kev pheej hmoo tsis sib xws: Dub tshwm grey, dawb tshwm dawb, thiab cov duab digital yog qhov muag plooj. Tshwj xeeb tshaj yog nyob rau hauv lub teeb muaj zog los yog oblique cov ces kaum, qhov kev nyeem ntawv yuam kev tus nqi nce nce. Siv lub tsheb dashboard ua piv txwv, yog tias qhov sib piv ntawm qhov sib piv tsawg dua 300: 1, tus neeg tsav tsheb tuaj yeem txhais cov ntaub ntawv ceev lossis roj qib tsis raug nyob rau hauv lub hnub ncaj qha, ua rau muaj kev nyab xeeb.
2, Kev lag luam daim ntawv thov scenarios: sib sib zog nqus correlation ntawm qhov sib piv thiab kev nyeem ntawv raug
Muaj qhov sib txawv tseem ceeb hauv qhov kev thov rau ntu code LCD sib piv ntawm cov kev lag luam sib txawv, thiab cov ntsiab lus tseem ceeb nyob hauv cov teeb pom kev zoo thiab kev nyeem ntawv zaus ntawm kev siv ib puag ncig.
1. Kev Tswj Xyuas Kev Lag Luam: Kev ruaj ntseg yuav tsum muaj nyob rau hauv ib puag ncig hnyav
Hauv kev lag luam xwm txheej xws li tshuaj lom neeg thiab hluav taws xob kev lag luam, cov cuab yeej siv feem ntau raug rau lub teeb muaj zog lossis hauv qhov chaw tsaus. High contrast (feem ntau ntau dua los yog sib npaug rau 1500: 1) xyuas kom meej tias cov zauv nyob twj ywm meej thiab txawv raws li hauv qab no tej yam kev mob:
Lub teeb muaj zog ib puag ncig: xws li dashboard ntawm lub chaw nres tsheb sab nraum zoov, qhov sib txawv siab tuaj yeem cuam tshuam qhov kev xav ntawm lub teeb pom kev zoo thiab zam cov lej raug "submerged" hauv lub teeb dawb.
Ib puag ncig tsaus ntuj: xws li chav tswj ntawm lub tshuab hluav taws xob nuclear, qhov sib txawv siab nyob rau hauv qhov ci qis tuaj yeem txo qhov pom kev qaug zog thiab txhim kho qhov tseeb ntawm qhov ntev - nyeem ntawv.
Case: Lub tuam txhab petrochemical siv cov khoom siv segmented LCD nrog qhov sib piv ntawm 2000: 1. Hauv kev sim tiag tiag hauv thaj chaw suab puam, qhov kev nyeem ntawv yuam kev raug txo los ntawm 72% piv rau cov ntxaij vab tshaus ib txwm muaj, thiab kev saib xyuas tau txuas ntxiv mus rau 18 lub hlis.
2. Cov khoom siv kho mob: kev xa cov ntaub ntawv tseem ceeb
Cov kev cai rau kev nyeem ntawv raug nyob rau hauv cov chaw kho mob yuav luag nruj. Ua ib qho electrocardiograph ua piv txwv, nws ntu code LCD yuav tsum ua kom tau raws li cov hauv qab no:
Dynamic contrast: Thaum saib xyuas lub plawv dhia sib txawv, lub vijtsam yuav tsum tau kho qhov sib piv ntawm lub sijhawm tiag tiag los qhia txog qhov tseem ceeb ntawm lub ncov thiab hav, tsis txhob txiav txim siab los ntawm cov ntaub ntawv sib tshooj.
Kev pom zoo sib xws: Thaum cov kws kho mob saib lub vijtsam los ntawm ntau lub kaum sab xis, qhov sib txawv ntawm qhov sib txawv yuav tsum tau tswj tsis pub dhau 10% kom ntseeg tau qhov tseeb ntawm ntau qhov chaw nres tsheb sib koom ua ke.
Cov ntaub ntawv: US FDA tus qauv yuav tsum muaj qhov sib piv zoo li qub ntawm Ntau dua lossis sib npaug rau 1200: 1 thiab lub sijhawm sib txawv ntawm qhov sib txawv ntawm tsawg dua lossis sib npaug li 5ms rau qib kev kho mob ntu ntu code LCDs kom phim lub sijhawm ntawm kev txiav txim siab kho mob- ua.
3. Automotive Electronics: Dual Protection of Safety and Experience
Lub tsheb dashboard yuav tsum tau ua haujlwm ruaj khov ntawm qhov kub ntawm -40℃txog 85 degree, thiab qhov sib piv tsim ntawm nws ntu LCD yuav tsum coj mus rau hauv tus account:
Kev them nyiaj kub: Kev ua haujlwm ntawm cov kua siv lead ua kua molecules txo qis hauv - qhov kub thiab txias ib puag ncig, thiab qhov sib piv yuav tsum tau tswj hwm los ntawm kev kho qhov tsav tsheb. Piv txwv li, ntawm -20 degree, qhov kev sib piv ntawm ib qho qauv txo qis ntawm 1000: 1 ntawm chav tsev kub rau 800: 1, tab sis cov ntaub ntawv log tsheb tseem tuaj yeem pom meej meej.
Anti reflective coating: Nyob rau hauv qhov cuam tshuam ntawm lub iav tsom iav los yog teeb pom kev tsaus ntuj, qhov sib txawv siab (feem ntau Zoo dua los yog sib npaug rau 800: 1) tuaj yeem txo qhov ci ntsa iab thiab txhim kho kev nyeem ntawv ceev.
Kev Xeem: Hauv European NCAP kev sib tsoo kev sib tsoo, ib qho kev ntsuas vaj huam sib luag nrog qhov sib piv ntawm Ntau dua lossis sib npaug rau 900: 1 txo tus neeg tsav tsheb cov tshuaj tiv thaiv lub sijhawm thaum muaj xwm txheej ceev los ntawm 0.3 vib nas this, txo qhov kev pheej hmoo ntawm kev sib tsoo.
3, Qhov sib txawv optimization tswvyim: technical iteration thiab scene adaptation
Txhawm rau txhim kho kev nyeem ntawv qhov tseeb ntawm ntu ntu code LCD, kev lag luam tau nthuav tawm cov thev naus laus zis los ntawm peb qhov ntev: cov khoom siv, tsav tsheb, thiab teeb pom kev zoo:
1. Kev tsim kho tshiab hauv cov ntaub ntawv siv lead ua kua: Kev hloov kho ntawm TN rau VATN
TN (twisted nematic hom): Tus nqi qis tab sis tsis sib xws (feem ntau Tsawg dua lossis sib npaug rau 500: 1), tsuas yog tsim rau cov txee yooj yim.
VATN (Vertical Alignment Type): Los ntawm vertically npaj cov kua siv lead ua kua molecules, cov xim dub ntshiab tom qab tau tiav, nrog qhov sib piv ntawm ntau dua 3000: 1, ua rau nws qhov kev xaiv zoo tshaj plaws rau siab -kawg khoom siv kho mob.
Case: Ib qho khoom siv ultrasonic portable los ntawm qee hom siv VATN ntu code LCD, uas txo cov duab nrov los ntawm 60% thiab txhim kho qhov tseeb ntawm 15%.
2. Optimization of Drive Technology: Inverted Drive thiab PWM Dimming
Rov qab theem tsav: Los ntawm kev hloov pauv qhov voltage polarity ntawm COM (common davhlau ya nyob twg) thiab SEG (segment davhlau ya nyob twg), cov duab seem uas tshwm sim los ntawm DC kev tsis ncaj ncees raug tshem tawm, thiab qhov sib piv zoo dua.
PWM dimming: dynamically adjusts backlight brightness los ntawm kev kho lub luag hauj lwm voj voog, tswj qhov zoo sib xws txawm nyob rau hauv tsawg brightness theem. Piv txwv li, nyob rau hauv hmo ntuj, qhov screen brightness ntawm ib tug ntse meter poob rau 10 cd / m ², tab sis qhov sib piv piv tseem nyob ntawm 800: 1.
3. Backlight Design Breakthrough: Partition Backlight thiab Mini LED
Muab faib backlight: Faib lub vijtsam mus rau ntau qhov chaw tswj lub teeb, thiab tua lub teeb pom kev sib raug zoo thaum pom cov keeb kwm yav dhau tsaus, txhim kho qhov sib txawv hauv zos. Piv txwv li, tom qab siv lub 8-zone backlight nyob rau hauv lub hauv paus tswj kev tshuaj ntsuam ntawm ib tug tej lub tsheb, qhov tsaus ntuj nti nthuav dav paub tus nqi nce 40%.
Mini LED: ua tiav phav phav theem ntawm segmented lub teeb tswj los ntawm micrometer theem LED chips, nrog qhov sib piv piv txog li 1000000: 1, tab sis tus nqi kuj yog siab heev. Tam sim no, nws yog siv nyob rau hauv siab -kawg tsheb HUD (head up zaub).
