Ib, Technical hauv paus ntsiab lus: Lub hauv paus ntsiab lus ntawm kev sib raug zoo ntawm lub hwj chim noj thiab lifespan
1. Kev ruaj ntseg thiab kev siv hluav taws xob ntawm cov ntaub ntawv siv lead ua kua
Lub hauv paus ntawm LCD yog cov kua siv lead ua kua molecules, nws txoj kev npaj yog tswj los ntawm hluav taws xob teb kom ua tiav cov zaub. Kev siv hluav taws xob feem ntau yog los ntawm ob yam:
Tsav hluav taws xob thiab tam sim no: Cov kua siv lead ua kua molecule deflection yuav tsum tau siv qhov hluav taws xob, thiab qhov kev tsav tsheb ntau dua thiab ntau pixels, qhov ntau dua qhov kev siv hluav taws xob. Piv txwv li, lub zog noj ntawm dynamic refresh hom (xws li 60Hz) yog 3-5 npaug ntawm cov zaub zoo li qub.
Backlight system: Tag nrho cov pob tshab LCD cia siab rau LED backlight, uas siv ntau dua 90% ntawm tag nrho lub zog. Qhov siab dua qhov backlight brightness, qhov ceev ntawm LED hlws ris kub nce, thiab tus nqi ntawm lub teeb lwj nce exponentially.
Kev cuam tshuam lub neej: Kev siv hluav taws xob ntau ua rau cov ntaub ntawv siv lead ua kua nyob hauv lub xeev siab hluav taws xob rau lub sijhawm ntev, uas tuaj yeem ua kom cov molecular polarization lossis electrochemical degradation; Qhov kub siab ntawm lub teeb pom kev zoo ncaj qha ua rau lub neej ntev ntawm LED. Piv txwv li, ib qho kev sim ntawm lub tsheb dashboard pom tias qhov backlight brightness poob ntawm 100% mus rau 60%, thiab LED lifespan ncua ntawm 30000 teev mus rau 60000 teev.
2. Kev ua tau zoo thiab kev laus ntawm kev tsav tsheb
Lub LCD tsav Circuit Court muaj xws li cov khoom xws li lub hwj chim tswj chips thiab lub sij hawm controllers, thiab nws lub hwj chim noj thiab efficiency ncaj qha cuam tshuam nws lifespan.
Tsawg impedance tsim: Qhov qis qis hauv cov kab hluav taws xob impedance, qhov me dua qhov poob tam sim no, thiab qis dua cov hluav taws xob tsim hluav taws xob, yog li ua kom qeeb ntawm kev laus ntawm cov khoom siv hluav taws xob. Piv txwv li, siv cov ntawv xov tooj tooj liab tsis siv cov ntawv txhuas tuaj yeem ua rau lub neej ntawm kev tsav tsheb los ntawm 20%.
Dynamic refresh thev naus laus zis: Los ntawm kev siv AI algorithms los kwv yees cov kev hloov pauv hauv cov ntsiab lus pom thiab tsuas yog hloov kho thaj chaw hloov tshiab, nws tuaj yeem txo qis kev siv hluav taws xob los ntawm 30% -50%. Tom qab siv cov thev naus laus zis no, tus nqi tsis ua haujlwm ntawm tus tsav nti hauv qee qhov ntsuas kev lag luam tau txo los ntawm 40%.
2, Cov ntaub ntawv kev lag luam: Kev sib raug zoo ntawm kev siv hluav taws xob thiab kev ua neej
1. Case study of car dashboard
Raws li cov ntaub ntawv xeem tiag tiag ntawm 200 lub tsheb qauv los ntawm Pacific Automotive Network:
Cov qauv siab kawg: Nruab nrog qis- zog E-INK backlight thiab dynamic dimming tshuab, dashboard LCD siv tsuas yog 0.5W ntawm lub zog thiab muaj lub neej ntev tshaj 10 xyoo.
Cov qauv kev lag luam: Cov tsoos LED backlit dashboard muaj lub zog siv li ntawm 2W thiab lub neej ntawm 5-8 xyoo.
Kev ntsuam xyuas ib puag ncig hnyav: Hauv qhov kub thiab txias los ntawm -40℃txog 85 degree, cov kua siv lead ua kua molecule kev ua haujlwm siab - lub zog ntsuas hluav taws xob txo peb zaug sai dua li cov qauv qis.
2. Kev xyaum ntawm cov cuab yeej tswj kev lag luam
CSDN blog txoj kev taug qab ntawm 500 cov cuab yeej hauv kev lag luam tshuaj qhia tau hais tias:
Power Optimization Group: Los ntawm PWM dimming, lub backlight brightness yog tswj ntawm 40%, thiab qhov nruab nrab lub hwj chim noj yog txo los ntawm 1.2W mus rau 0.4W, nrog ib tug tsis ua hauj lwm tus nqi ntawm tsuas yog 2% nyob rau hauv 5 xyoo.
Pab pawg tswj: Tswj 80% ci ntsa iab, haus 0.8W lub zog, thiab muaj qhov tsis ua haujlwm ntawm 15%. Qhov teeb meem tseem ceeb yog LED teeb lwj ua rau pom qhov muag tsis pom.
3. Kev sib piv ntawm cov khoom siv hluav taws xob
Kev txheeb xyuas ntxiv ntawm kev sib raug zoo siv cov ntaub ntawv los ntawm kev lag luam xov tooj ntawm tes:
Lub xov tooj LCD: nruab nrab lub zog siv ntawm 3W, lub sijhawm ua haujlwm ntawm lub vijtsam yog li 30000 teev (xws li raws li 8 teev ntawm kev siv txhua hnub, kwv yees li 10 xyoo).
OLED xov tooj: Lub zog noj ntawm 2.5W, tab sis cov khoom siv organic yog qhov ua rau muaj kev laus thiab muaj sia nyob tsuas yog 20000 teev. Txawm hais tias OLED muaj kev siv hluav taws xob qis dua, nws cov khoom siv ua rau lub neej luv dua li qhov ua tau zoo ntawm cov LCDs.
3, Cov yam tseem ceeb cuam tshuam: Lub neej txiav txim siab tshaj qhov kev siv hluav taws xob
1. Kev tswj hwm ib puag ncig
Kev tswj qhov kub thiab txias: LCD iav substrate muaj cov thermal conductivity tsis zoo, thiab cov cua kub sib sau ua ke hauv qhov chaw kaw yuav ua rau lub zos kub siab tshaj tus qauv. Ib lub ntsuas ntse ntse txo nws qhov kub thiab txias los ntawm 15℃thiab txuas ntxiv nws lub neej los ntawm 40% los ntawm kev ntxiv graphene cua sov dab dej.
Kev tiv thaiv av noo: Cov av noo ib puag ncig tuaj yeem yooj yim ua rau hluav taws xob corrosion. Cov cuab yeej nrog IP67 tiv thaiv qib muaj 60% qis qis dua tus qauv zoo tib yam.
2. Kev xaiv cov khoom siv
Cov kua siv lead ua kua: Cov ntaub ntawv siv lead ua kua nrog ntxiv cov stabilizers tuaj yeem tiv taus kev tsav tsheb ntau dua yam tsis muaj degradation. Lub chaw tsim khoom siv kho mob tau nce lub neej ntawm LCD los ntawm 5 xyoo mus rau 8 xyoo los ntawm kev txhim kho cov qauv.
Backlight thev naus laus zis: Mini LED backlight tswj lub teeb los ntawm ntau txhiab thaj chaw, txo kev siv hluav taws xob los ntawm 30% thaum txuas lub neej ntawm 50000 teev mus txog 80000 teev.
3. Hom kev siv
Cov zaub zoo li qub: xws li cov cim npe hluav taws xob, tsuas yog microampere theem tam sim no yuav tsum tau tswj cov zaub, thiab lub neej ntev tuaj yeem ncav cuag ntau tshaj 10 xyoo.
Dynamic zaub: xws li nyob rau hauv lub tsheb navigation, nquag refreshing ua rau ib tug surge ntawm lub hwj chim noj thiab ib tug luv luv lifespan ntawm txog 5 xyoo.
4, Kev Lag Luam Kev Lag Luam: Kev sib koom ua ke ntawm kev siv hluav taws xob tsawg thiab lub neej ntev
1. Kev taw qhia txog kev siv tshuab thev naus laus zis
Reflective LCD: qhia siv lub teeb pom kev zoo, ua tiav lub teeb rov qab, txo lub zog siv qis dua 0.1mW, thiab muaj lub neej ntev tshaj 15 xyoo.
Quantum dot thev naus laus zis: txhim kho lub teeb pom kev zoo, txo qis kev siv hluav taws xob los ntawm 15% ntawm tib lub teeb ci, thiab txuas ntxiv LED lifespan.
AI lub zog-txuag algorithm: kwv yees tus neeg siv tus cwj pwm los ntawm kev kawm tshuab, dynamically kho tus nqi refresh thiab brightness, thiab ua tiav scene raws li lub zog-txuag.
2. Cov qauv thiab ntawv pov thawj
Lub tsheb qib tus qauv: Lub ntsuas ntsuas LCD yuav tsum muaj lub neej ntev tsis pub tsawg tshaj 10 xyoo nyob rau hauv cov xwm txheej hnyav xws li -40℃txog 85℃thiab cuam tshuam kev co.
Energy Star daim ntawv pov thawj: Nws tau teev tseg tias lub zog siv ntawm cov khoom lag luam LCD yuav tsum tsawg dua 0.5W / nti ², txwv tsis pub lawv tuaj yeem nkag mus rau European thiab Asmeskas kev lag luam.
