Kev siv lub hauv paus ntawm kev ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob: kev sib koom tes ntawm cov kua - cov khoom siv lead ua thiab tsav tsheb.
Electric Field Response Yam ntxwv ntawm Liquid Crystal Material
Raws li kev cuam tshuam ntawm hluav taws xob teb ntawm kev hloov pauv hauv kev teeb tsa ntawm cov kua siv lead ua kua molecules ntawm LCD zaub. TN piv txwv; Thaum tsis muaj qhov hluav taws xob, cov molecules npaj lawv tus kheej hauv cov duab corkscrew uas tso cai rau lub teeb hla kev ywj pheej, tab sis thaum muaj hluav taws xob tau qhia lawv txoj kab sib txuas nrog txhua yam tsim hluav taws xob uas thaiv lub teeb tag nrho. Cov txheej txheem no muaj kev cuam tshuam rau qhov pib voltage.
Qhov Threshold Vltage lossis Vth yog qhov tseem ceeb ntawm qhov hluav taws xob hauv volts uas yuav pib qhov deflecting ntawm cov kua siv lead ua kua molecules thiab tus lej no feem ntau tuaj yeem pom nyob ib puag ncig 2 - 3 volts.
Saturation voltage (Vsat), qib voltage uas yuav tsum tau ua kom tiav tag nrho cov deflection ntawm cov kua muaju, feem ntau yog hais txog 4 - 6 V.
Thiab niaj hnub ntsuas LCDs, lawv tuaj yeem tau txais lawv Vth tag nrho hauv qab 1. 5V yog tias koj siv cov khoom zoo xws li kev ua kom zoo rau cov kua siv lead ua kua zaub mov (ntxiv fluoro- lossis cyano- tej yam?), tseem yuav zoo nkauj zoo nkauj ntawm cov khoom ci tsaus> 1000 : 1 tab sis ceev li 10 milliseconds yog li ntawd peb xav tau hom kev lag luam.
Tsawg voltage tsim ntawm Tsav Circuit Court.
Cov tsoos LCD tsav tsheb Circuit Court yuav coj mus rau hauv lub hwj chim mov uas tau coj los ntawm ib kauj ruam ntxiv thiab nws mus tag nrho txoj kev mus txog kaum mus rau nees nkaum volts thiaj li yuav hwj chim rau koj cov kua siv lead ua kua zaub, tab sis tam sim no koj muaj hom technology nyob rau hauv ntau ntawm ib tug niaj hnub ntsuas LCD xws li qhov no. Lub tshuab peb tab tom saib tuaj yeem ua qhov tsis tshua muaj hluav taws xob zoo ntawm nws tus kheej.
Kev sib xyaw tsav tsheb IC: xws li SED1520, T6963c thiab lwm yam, cov twj tso kua mis sib xyaw ua ke, tuaj yeem nce 3.3V rau hauv qhov tsim nyog voltage ntawm cov kua siv lead ua kua, thiab tuaj yeem txuas ncaj qha mus rau I / O chaw nres nkoj ntawm microcontroller, yog li txo qhov ntau ntawm cov khoom siv sab nraud.
DVS: Dynamically hloov cov tsav tsheb voltage nyob ntawm seb qhov uas tau qhia. Zoo li kev txiav qhov hluav taws xob mus rau 2.5V thaum pom qee cov ntawv thiab tsa rov qab mus rau 3.3V rau kev nthuav tawm cov duab txav, txuag ntawm ob qho tib si siv hluav taws xob thiab cov txiaj ntsig tau txais.
Tsawg lub zog zaub hom: Nws tuaj yeem txhawb nqa ib nrab refresh thiab pw tsaug zog ua haujlwm. Piv txwv li, lub ntsuas hluav taws xob ntse tsuas tuaj yeem hloov kho lub sijhawm tso saib feem thaum nws nyob ntawm qhov muag, uas txo nws txoj kev siv hluav taws xob tsawg dua 0.1mW.
Kev lag luam Daim ntawv thov rooj plaub: Kev siv hluav taws xob qis qis LCD siv.
Muaj cov twj paj nruag: ua haujlwm nyob rau hauv cov xwm txheej nyuaj.
Hauv petrochemsitry/metallurgy thiab lwm yam twj paj nruag ua haujlwm los ntawm -40 degrees mus rau +85 degress. Qee hom kev lag luam HMI cov cuab yeej siv lub LCD uas yog txias-hardened thiab khiav los ntawm cov thev naus laus zis no.
Ua nyob rau hauv cov cua sov zaj duab xis: Ib qho ITO cua sov zaj duab xis yog kev koom ua ke nyob rau hauv lub LCD lub substrate thiab yog ua ke nrog lub backlight qhov chaw; Tus nqi ntawm cov hluav taws xob siv hluav taws xob yog tswj tau los ntawm kev ntsuas qhov ntsuas kub kom txhua yam ua haujlwm zoo ntawm 3.3 Volts nyob rau hauv qis kub (tsis zoo nees nkaum degrees Celsius).
Widening tsim ntawm lub hwj chim mov: Nws txhawb ib tug 9-36V input, muab ib tug ruaj khov 3.3V los ntawm txoj kev ntawm DC-DC hloov dua siab tshiab, nws muaj peev xwm hloov mus rau txawv voltages ntawm qhov chaw ua hauj lwm.
Smart meter: kev daws teeb meem los tso saib nrog lub roj teeb lub neej ntev heev
Smartmeters yuav tsum ua haujlwm ntev (ntau tshaj 10yrs) thiab lawv kuj siv zog ntau dua. Ib qho qauv ntawm ib theem hluav taws xob ntsuas hluav taws xob uas tau txais kev cuam tshuam hom LCD raws li nws cov zaub muaj cov haujlwm qis qis hauv qab no.
backlight-dawb tsim: siv lub teeb ci ntsa iab los cuam tshuam ntawm koj lub vijtsam yog li tsis muaj teeb pom kev zoo thiab nws yuav ua haujlwm ntawm 2v lossis qis dua.
Segmented tsav tsheb tech: Cov ntsiab lus pom tau muab faib ua ntau yam. Tsav txhua feem ntawm tus kheej kom txo qis kev siv hluav taws xob tsis tsim nyog. Kev ntsuas cov ntaub ntawv, nws tuaj yeem pom los ntawm daim duab saum toj no, lub ntsuas hluav taws xob tso tawm tsuas yog 0. 05 mW / cm 2 hauv qhov hluav taws xob ntawm 3.3V.
Cov khoom siv kho mob: Ua ntej ntawm tag nrho cov, Kev Nyab Xeeb ua ntej Tsawg Voltage Tsim
Kev ua haujlwm tsis tshua muaj hluav taws xob txo qis kev pheej hmoo kom tau txais Hluav Taws Xob Hluav Taws Xob hauv lub ntsuas hluav taws xob portable, Ntshav Qab Zib ntsuas thiab lwm yam. Thiab tam sim no, rau ib hom khoom tshwj xeeb ntawm tes- tuav saib lawv tau suav nrog hom kev nyab xeeb hauv qab no.
Kev sib cais ntawm cov khoom siv hluav taws xob: Kev sib cais ntawm cov tswv yim thiab cov khoom siv los ntawm kev siv lub tshuab hloov pauv, xyuas kom meej tias qhov hluav taws xob hauv qhov kev sib cuag nrog tus neeg mob qis dua 6V.
Dul Battery Redundancy: ua nrog 2 * 1.5V AA, lub zog 3.3V los ntawm lub zog, tseem qhia tom qab ib lub roj teeb tuag.
Cov teeb meem kev ntseeg siab thiab kev daws teeb meem.
Nyob rau hauv qis voltage, tso saib teeb meem Uniformity.
Yog tias volt qis dua 2.5V ces lub lcd yuav tsim qhov tsaus nti vim tsis txaus deflect. Kev daws yog:
Lub teeb qhia phaj kev ua kom zoo dua qub: micro prism lub teeb qhia phaj los txhim kho lub teeb rov qab siv. Ib yam li lwm cov ntaub ntawv xws li thaum lub tsheb dashboard lub LCD tuaj yeem ua kom nws qhov ci ntsa iab mus txog 92% tsuas yog los ntawm kev siv lub teeb qhia sib txawv ntawm peb volts (3v) hluav taws xob.
Dynamic contrast adjustment: Kho cov duab sib piv tau raws li lub zog ntawm ib puag ncig lub teeb. Ib puag ncig lub teeb muaj zog (> 10000lux ) Qhov sib txawv nce mus rau 1000: 1, txhawm rau txhawm rau txo qis ntawm qhov ci vim qhov txo qis qis.
teb qeeb nyob rau hauv qis temp ib puag ncig
Cov kua ua kua muaj lawv cov viscosities tau siab dua thaum nws txias thiab ua rau lawv lub sijhawm ua haujlwm. Ib qho tshwj xeeb tsheb khiav ceev-board LCD kho qhov teeb meem no nrog cov thev naus laus zis no:
ITO heating film: Transparent heating films on either side of the liquid crystal layer for keeping the temp. at >0℃nrog ceev cov tshuaj tiv thaiv<15ms.
Preheat algo: Thaum pib lub cuab yeej cov kua siv lead ua kua tau muab lub zog siab ntawm 5V pib, ces kub nce nrawm thiab tom qab ntawd nws mus rau tus qauv 3. 3V.
Lub sij hawm ntev tsis tshua muaj hluav taws xob lwj ntawm lifespan.
Cov ntaub ntawv LCM tuaj yeem muaj cov electrolytes ntawm qhov tsis tshua muaj hluav taws xob ntev thiab cov duab tawg. Indusrial tswj LCD nce nws lub neej lub sij hawm los ntawm kev ua li ntawd:
AC tsav waveform: Siv lub symmetric square-yoj tsav los tiv thaiv DC offset, electrolysis tus nqi txo los ntawm 90%.
Hloov cov khoom siv: Ntxiv cov tshuaj antioxidants rau LC los tiv thaiv corrosion ntawm electrode. Raws li peb qhov kev sim tiag tiag peb pom tias nws yuav ua tau rau lcd ua haujlwm tsis tu ncua saum tus nqi ntawm 50000 nrog qhov hluav taws xob ntawm 2.5V.
