Ib, Cov Nta: Cov "AIoT Gene" ntawm Segment LCD
1. Ultra tsawg zog noj: qhov kawg daws rau roj teeb lub neej ntxhov siab vim
Ib qho ntawm cov ntsiab lus mob tseem ceeb ntawm AIoT cov cuab yeej yog lub roj teeb lub neej, tshwj xeeb tshaj yog rau cov roj teeb siv hluav taws xob, cov twj paj nruag, thiab lwm yam khoom siv. Lub zog kom zoo dua ntawm segmented LCD nyob rau hauv nws "passive zaub" feature: nws tsuas yog siv lub zog thaum lub xeev hloov, thiab kev khiav hauj lwm tam sim no tsawg li microamperes (μ A). Piv txwv li, ib qho cuab yeej ntse ua liaj ua teb hauv av tau txais cov ntu code LCD, thiab thaum tso saib cov ntaub ntawv nitrogen, phosphorus, thiab potassium, tag nrho lub zog siv ntawm lub tshuab tsuas yog 2.2 μ A. Thaum ua ke nrog lub hnub ci zog, nws tuaj yeem ua tiav "zero tu" ua haujlwm. Hauv qhov sib piv, lub zog siv ntawm TFT-LCD ntawm tib qhov loj tuaj yeem ncav cuag 150-300mA, yuav tsum tau hloov roj teeb ntau zaus lossis cov khoom siv hluav taws xob sab nraud, nce kev ua haujlwm thiab cov nqi tu.
2. Kev ntseeg siab: "txoj cai ciaj sia" ntawm kev lag luam scenarios
AIoT cov cuab yeej siv feem ntau ntsib qhov xwm txheej huab cua xws li kub siab, tsis tshua muaj kub, kev co, thiab kev cuam tshuam hluav taws xob, uas ua rau muaj kev txwv nruj rau kev ntseeg siab ntawm cov khoom lag luam. Qhov yooj yim ntawm cov qauv ntawm segmented LCD tau dhau los ua nws qhov txiaj ntsig zoo:
Los tiv thaiv kev co: Tsis muaj txheej txheej nyias nyias, lub iav substrate thickness tsuas yog 1/3 ntawm TFT-LCD, nrog kev cuam tshuam muaj zog;
Kev hloov kho qhov kub thiab txias: Los ntawm kev kho cov khoom siv LCD xws li BTN thiab VATN, kev ua haujlwm kub tuaj yeem txuas mus rau -40℃~ 105℃kom tau raws li qhov xav tau ntawm cov khoom siv sab nraum zoov;
Los tiv thaiv electromagnetic cuam tshuam: Lub voj voog tsav tsheb yog qhov yooj yim, thiab electromagnetic compatibility (EMC) zoo dua li qhov nyuaj ntawm TFT-LCD tsav tsheb. Nws tuaj yeem tiv taus qhov muaj zog electromagnetic ib puag ncig (xws li kev hloov pauv zaus thiab lub cev muaj zog).
Piv txwv li, qee qhov kev soj ntsuam cov roj kav dej siv cov khoom siv ntu ntu LCD tuaj yeem ua haujlwm tsis tu ncua rau 5 xyoos yam tsis muaj kev ua haujlwm hauv thaj tsam ntawm -30℃, thaum yog siv TFT-LCD, nws nquag ua haujlwm tsis zoo vim muaj teeb meem qis qis.
3. Tus nqi qis: "kev lag luam qib" rau cov ntawv loj -
Qhov nrov ntawm AIoT cov cuab yeej tso siab rau kev tswj hwm tus nqi, thiab tus nqi kom zoo dua ntawm segmented LCD yog xav txog peb yam:
Tus nqi ntawm cov khoom siv: Tus nqi ntawm 5-inch segmented LCD module yog kwv yees li 2-4 US las, uas tsuas yog ib feem peb ntawm tib qhov loj TFT-LCD (8-12 US las);
Kev tsav tsheb yooj yim: Nws tuaj yeem tsav los ntawm tus nqi qis -MCUs xws li 51 microcontrollers, nrog tus nqi tsav tsheb IC tsawg dua $ 0.5, thaum TFT-LCD yuav tsum muaj siab- kev ua haujlwm tseem ceeb ntawm nti, uas nce tus nqi ntau zaus;
High yield: Lub segmented LCD thev naus laus zis yog cov paub tab, nrog cov txiaj ntsig ntawm ntau dua 98%, thaum TFT-LCD feem ntau muaj cov txiaj ntsig ntawm 85% -90% vim qhov nyuaj ntawm cov txheej txheem nyias nyias.
Qhov txiaj ntsig zoo li no ua rau segmented LCD irreplaceable nyob rau hauv AIoT pab kiag li lawm uas yog loj - ua nyob rau hauv lub lab theem.
2, Daim ntawv thov scenario: "Precise positioning" ntawm ntu LCD
1. Tsau cov ntsiab lus tso saib: "Qhov tseem ceeb ntawm kev ua haujlwm" rau cov cuab yeej siv khoom lag luam
Cov cuab yeej siv xws li ntsuas ntsuas siab, ntsuas ntsuas kub, thiab ntsuas ntsuas ntsuas yuav tsum tau ntev- lub sij hawm tso saib ntawm cov nqi ruaj khov lossis cov cim xwm txheej, nrog rau cov kev daws teeb meem tsawg tab sis muaj kev ntseeg siab thiab siv hluav taws xob tsawg. Ntu code LCD tuaj yeem ua tau zoo tso saib cov lej, cov ntawv, thiab cov duab yooj yim los ntawm kev hloov cov lej ntu, ua tau raws li qhov xav tau ntawm cov cuab yeej siv. Piv txwv li, tom qab siv cov txheej txheem LCD segmented, tag nrho cov kev siv hluav taws xob ntawm ib lub ntsuas ntse tsuas yog 6mA, thiab lub roj teeb lub neej yog peb zaug ntev dua li TFT-LCD scheme, ua tau raws li kev tsim lub neej ntawm ntau tshaj 10 xyoo.
2. Tsawg zaus hloov tshiab scenario: "zog-txuag thov" rau kev saib xyuas ib puag ncig
Cov cuab yeej saib xyuas ib puag ncig (xws li cov cuab yeej ntsuas huab cua thiab cov ntsuas dej zoo) yuav tsum tau hloov kho cov ntaub ntawv ib teev lossis txhua hnub, nrog rau cov ntsiab lus tsawg zaus. Kev siv hluav taws xob zoo li qub ntawm segmented LCD yog qhov tseem ceeb. Piv txwv li, ib qho cuab yeej ntse ua liaj ua teb hauv av kuaj pom cov ntaub ntawv nitrogen, phosphorus, thiab poov tshuaj nyob rau lub sijhawm tiag tiag los ntawm segmented LCD, nrog lub zog siv tsuas yog 2.2 μ A. Thaum ua ke nrog lub hnub ci zog, nws tuaj yeem ua tiav "zero txij nkawm" ua haujlwm.
3. Monochrome/Bicolor Requirements: "Nqis Sensitive" Industrial Control
Cov cuab yeej tswj kev lag luam (xws li PLC, HMI) feem ntau xav tau los tso saib cov ntsiab lus monochrome xws li teeb pom kev xwm txheej thiab cov ntaub ntawv ceeb toom. Segment code LCD tuaj yeem ua tiav cov duab monochrome liab, daj, xiav, thiab lwm yam los ntawm cov ntxaij lim dej, thiab tus nqi qis dua RGB sub-pixel qauv ntawm TFT-LCD. Piv txwv li, lub Hoobkas cov kab ntau lawm maub los siv 3-inch segmented LCD, uas ua tau raws li cov lus qhia kom pom tseeb thiab muaj tus nqi 70% qis dua TFT-LCD tov.
4. Customization yuav tsum tau: "kev pom lus" ntawm hom kev sib txawv
Nyob rau hauv lub caij nyoog tam sim no ntawm homogenization loj ntawm AIoT li, qhov sib sib zog nqus customization muaj peev xwm ntawm ntu LCD tau dhau los ua cov cuab yeej muaj zog rau cov hom lag luam kom tawg. Cov lag luam tuaj yeem hloov kho cov cim tshwj xeeb, cim, fonts, thiab txawm tias layouts los ua kom cov duab sib cuam tshuam ib feem ntawm lawv cov hom DNA. Piv txwv li, customizing lub "Steam" thiab "Coffee Beans" icons ntawm lub siab -kho kas fes tshuab instantly txhim kho cov khoom professionalism thiab paub; Ib lub khob dej ntse qhia cov ntaub ntawv xws li dej kub thiab ntim los ntawm ntu ntu code LCD, nrog rau qhov yooj yim thiab kev siv thev naus laus zis.
3, Kev Txhim Kho Kev Lag Luam: Kev Txhim Kho Tshiab ntawm Segment LCD
Txhawm rau kov yeej qhov tsis txaus ntawm cov ntu ntu LCD, xws li nqaim saib lub kaum ntse ntse thiab ib qho xim, kev lag luam nthuav dav nws daim ntawv thov ciam teb los ntawm kev hloov kho thev naus laus zis hauv qab no:
Cov khoom siv sib txawv siab: siv VATN (vertically oriented twisted nematic) kua siv lead ua kua, qhov sib piv piv tau nce ntawm 5: 1 txog 20: 1, nce mus txog qib TFT-LCD;
Ntau xim ntu code npo: Los ntawm kev sib tshooj xim cov ntxaij lim dej, xim liab, ntsuab, thiab xiav xim yog tso tawm kom tau raws li cov duab kos duab;
Kev faib tawm backlight tswj: Faib lub vijtsam rau hauv 4-8 thaj chaw thiab tsuas yog tig lub teeb rov qab rau thaj chaw uas yuav tsum tau tso tawm, txo qis kev siv hluav taws xob ntau dua 50%;
Tsawg zog tsav IC: Launched tsav chips uas txhawb dynamic voltage tswj (xws li HT1625), txo hwj chim noj los ntawm 40% piv rau cov tsoos ICs.
Piv txwv li, qee qhov ntse chessboard siv segmented LCD los qhia cov xwm txheej xws li "HUBAN", "AI", "THINK", thiab lwm yam, ua ke nrog MSP430 qis- zog MCU, tag nrho cov tam sim no ntawm lub tshuab tsuas yog 1.8 μ A, thiab lub roj teeb lub neej tuaj yeem kav ntev li ob peb xyoos.
