Hauv lub ntiaj teb ntawm cov khoom siv hluav taws xob, cov duab qhia ua lub luag haujlwm tseem ceeb hauv kev siv cov cuab yeej siv li cas. Ntawm ntau hom kev qhia muaj, LCD (Liquid Crystal Display) thev naus laus zis tau dhau los ua kev xaiv nrov, tshwj xeeb tshaj yog hauv cov ntawv thov xws li cov ntsuas ntsuas ntse. Kab lus no yuav tshawb txog qhov sib txawv ntawm LED thiab LCD zaub, thiab muab kev taw qhia txog kev xaiv qhov zooLCD zaub rau ntse ntsuas.
LCD zaub yog dab tsi?
Lub LCD zaub siv cov kua siv lead ua kua los tsim cov duab. Cov crystals no yog sandwiched ntawm ob txheej iav los yog yas, thiab thaum siv hluav taws xob tam sim no, lawv ua raws li txoj kev uas lawv thaiv los yog cia lub teeb hla. Cov thev naus laus zis no tau siv dav hauv ntau yam khoom siv, los ntawm TV mus rau smartphones, thiab tshwj xeeb tshaj yog nyiam rau nws lub peev xwm los tsim cov duab ntse nrog kev siv hluav taws xob tsawg.
Qhov txawv ntawm LED thiab LCD zaub yog dab tsi?
Thaum cov ntsiab lus LED thiab LCD feem ntau siv sib hloov, lawv xa mus rau cov thev naus laus zis sib txawv. Thawj qhov sib txawv yog nyob rau hauv txoj kev backlighting siv nyob rau hauv cov zaub.
Backlighting:
LCD Zaub: Cov LCDs ib txwm siv cov teeb fluorescent rau backlight. Qhov no txhais tau hais tias cov xim thiab qhov ci ntawm cov zaub tuaj yeem tsis tshua muaj zog dua li cov duab LED.
LED Zaub: LED zaub yog ib qho tseem ceeb ntawm LCD uas siv lub teeb-emitting diodes (LEDs) rau backlight. Qhov no tso cai rau kev sib piv zoo dua, sib sib zog nqus dub, thiab cov xim zoo nkauj dua. Tsis tas li ntawd, LED zaub tuaj yeem ua nyias thiab sib dua dua li cov LCDs ib txwm muaj.
Zog Efficiency:
LED zaub feem ntau siv zog ntau dua li cov LCDs ib txwm muaj. Lawv haus tsawg zog, uas yog ib qho txiaj ntsig zoo rau cov khoom siv roj teeb xws li cov ntsuas ntsuas ntse.
Xim Accuracy thiab Brightness:
LED cov lus qhia yuav muab cov xim zoo dua thiab qhov ci ntsa iab piv rau cov qauv LCDs. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas qhov pom meej meej yog qhov tseem ceeb, xws li nyob rau hauv ib puag ncig sab nraum zoov.
Lifespan:
LED zaub feem ntau muaj lub neej ntev dua li cov LCDs ib txwm muaj, ua rau lawv muaj kev xaiv ruaj khov rau kev siv mus ntev.
Yuav xaiv ib qhoLCD zaubrau Smart Meters
Thaum xaiv ib qho LCD zaub rau lub ntsuas ntsuas ntse, ntau yam yuav tsum tau txiav txim siab los xyuas kom meej qhov kev ua tau zoo thiab cov neeg siv kev paub.
Loj thiab daws teeb meem:
Qhov loj ntawm cov zaub yuav tsum tsim nyog rau kev npaj siv. Cov zaub loj dua tuaj yeem nyeem tau yooj yim dua, tab sis nws kuj tseem yuav tsum tau ua kom haum rau hauv cov qauv tsim ntawm lub ntsuas ntsuas ntse. Kev daws teeb meem tseem ceeb sib npaug; Cov kev daws teeb meem siab dua muab cov duab meej dua thiab cov ntawv nyeem, uas yog qhov tseem ceeb rau kev nthuav tawm cov ntaub ntawv kom raug.
Brightness thiab Contrast:
Txij li cov ntsuas ntsuas ntse yuav siv tau rau hauv ntau yam teeb pom kev zoo, nws yog ib qho tseem ceeb uas yuav tau xaiv cov zaub uas muaj qhov ci txaus thiab qhov sib txawv. Cov zaub uas tuaj yeem kho nws qhov ci ci raws li lub teeb pom kev nyob ib puag ncig yuav txhim kho kev nyeem tau thiab cov neeg siv kev paub.
Kev siv fais fab:
Muab hais tias cov ntsuas ntse ntse feem ntau siv roj teeb lossis cia siab rau kev siv hluav taws xob tsawg, xaiv lub zog siv hluav taws xob LCD yog qhov tseem ceeb. LED-backlit LCDs feem ntau siv zog ntau dua li cov LCDs ib txwm muaj, ua rau lawv xaiv zoo dua rau cov ntsuas ntsuas ntse.
Durability thiab Environmental Resistance:
Cov ntsuas ntse ntse feem ntau ntsia sab nraum zoov lossis hauv qhov chaw hnyav. Yog li ntawd, xaiv LCD zaub yuav tsum ua kom ruaj khov thiab tiv taus ib puag ncig xws li ya raws, plua plav, thiab kub hloov pauv. Saib rau cov khoom uas muaj cov txheej tiv thaiv lossis cov ntaub thaiv npog uas tuaj yeem tiv taus cov xwm txheej no.
Saib lub kaum ntse ntse:
Lub kaum sab xis saib ntawm cov zaub yog lwm qhov tseem ceeb. Lub kaum sab xis pom dav kom ntseeg tau tias cov ntaub ntawv ntawm cov zaub tuaj yeem nyeem tau los ntawm ntau txoj haujlwm, uas yog qhov tseem ceeb tshwj xeeb hauv cov pej xeem lossis cov chaw sib koom.
Touchscreen muaj peev xwm:
Raws li kev ua haujlwm ntawm lub ntsuas ntsuas ntse, lub touchscreen LCD zaub yuav muaj txiaj ntsig zoo. Touchscreen interfaces tuaj yeem txhim kho cov neeg siv kev sib cuam tshuam thiab ua kom yooj yim rau kev taug kev los ntawm cov chaw sib txawv thiab cov ntaub ntawv.
Tus nqi:
Thaum kawg, xav txog cov peev nyiaj rau lubLCD zaub. Thaum nws yog ib qho tseem ceeb rau kev nqis peev rau hauv cov khoom lag luam zoo, nws tseem ceeb heev kom nrhiav tau qhov sib npaug ntawm kev ua tau zoo thiab tus nqi. Ntsuam xyuas cov kev xaiv sib txawv thiab xaiv cov zaub uas ua tau raws li qhov tsim nyog tshwj xeeb yam tsis muaj ntau tshaj qhov peev nyiaj.
