, Lub neej muaj sia ntawm Segmented LCD: Dual Constraints Cov Ntaub Ntawv thiab Cov Txheej Txheem
Lub neej ntawm ntu LCD yog tsuas yog txiav txim siab los ntawm peb yam: electrode khoom ruaj khov, ntim cov txheej txheem kev cia siab, thiab kev tsav tsheb hluav taws xob, thiab kev tsav tsheb hluav taws xob, thiab kev tsav tsheb hluav taws xob, thiab cov qauv tsav tsheb. Noj muaj qeb Seem Code LCD ua piv txwv, nws cov khoom siv hluav taws xob suav nrog cov cog rau hauv qab (anyotropic coj cov nplaum) kev sib koom tes. Cov tsav tsheb ncig ntawm MCU ua - hauv maub los lossis tsav tsheb sab nraud (xws li HT1621).
Cov khoom siv hluav taws xob cov khoom qub: ito electrodes yog nquag rau corrosion rau hauv acidic ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv cov kub thiab huab cua siab. Kev ntxhov siab ntawm electrode thiab lub khob substrate tuaj yeem nrawm hauv tshuab hluav taws xob, ua kom pom kev tawg lossis tshuaj ntsuam distortion. Ib qho kev ntsuas tsheb lag luam automotive pholes ib zaug ua tsis tiav los siv anti {2} Kev ntsuas ntsev li ntawm 48 teev nyob rau hauv cov nyiaj ntsev ntau dua li ib lab yuas.
Ntim ntim cov txheej txheem ua tsis tiav: cov khoom seem hauv cov acf sib txuas ntawm cov pob loj uas muaj lub ntsej muag micros thaum muaj teeb meem dub, feem ntau tau ua rau cov pob corrosion, feem ntau tau manifested li dub me me hauv thaj chaw zaub. Qee qhov chaw tsim khoom lag luam tsim kho kom zoo rau ACF dav ntsuas kom txo tau cov khoom ntawm nws cov khoom lag luam los ntawm 45% hauv 60℃/ 90% rh sim.
Tsav Circuit Court poob: kev hloov zuj zus tuaj yeem ua rau them rov qab capacitors hauv lub capacitors sab hauv, nrawm qhov kev puas tsuaj ntawm Oxide txheej. Piv txwv li, ib ntu ntu LCD los ntawm cov cuab yeej kho mob uas muaj cov khoom siv kho mob uas muaj cov zaub uas tau flickering tom qab 100,000 lub zog ntawm / tawm mus ncig ua txhaum cai.
2, Feem ntau qhib cov xwm txheej: Kev sib tw ntawm qhov kub thiab txias thiab lub teeb lwj
Thaum cov cuab yeej siv tau khiav ib txwm, Segmented LCD ntsej muag ob qho teeb meem tseem ceeb: Backlight attlication thiab qhov kub thiab qhov ntsuas kub.
Backlight attenuation: lub backlight System ntawm segmented LCD feem ntau siv lub teeb pom kev zoo los ntawm tam sim no, cua sov dissipation, thiab khoom zoo. Lub neej muaj kev muaj qib qib LED Backlight tuaj yeem ncav cuag 500 teev, tab sis yog tias nws ua haujlwm ntawm qhov siab ntev, tus nqi ntawm txoj kev nyab yuav nrawm nrawm. Piv txwv li, qee yam khoom siv sab nraum zoov Handheld ntaus ntawv ua tsis tau zoo, ua rau muaj 30% txo qis ntawm lawv cov khoom lag luam tsis pub dhau 2 xyoos.
Kev ntsuas kub: Qhov kev ua haujlwm kub ntau ntawm Segmented LCD feem ntau {}}}}}}}}} {degree kom nrawm rau hluav taws xob thiab polarizer laus. Ib qho chaw nres tsheb hluav taws xob ntxiv cov khoom lag luam ntxiv rau sab tom qab ntawm 85 qib kev ua haujlwm tsis ntev los ntawm 85℃zoo dua li kev tsim qauv tsis muaj cua sov li 30%.
Txhim Kho Rau Lub Tswv Yim:
Dynamic Dimming: Txiav kho lub backlight ci ci raws li lub teeb pom kev zoo. Piv txwv li, cov cuab yeej siv xov tooj ntse tau ua tiav 40% txo qis hauv Backlight Fais Fab siv los ntawm lub sensor coj, thaum txuas lub sijhawm LED lifespan rau 80000 teev.
Thermal Kev tswj hwm kev tswj hwm: Thermal kev coj ua silicone yog siv los sau qhov sib txawv ntawm cov thermmented lcd thiab ua kom muaj qhov kub thiab txias tshaj li 60 degree.
3, extrant tawm cov xwm txheej: zais zais kev hem thawj ntawm hluav taws xob zoo li qub thiab noo noo
Thaum cov cuab yeej siv lag luam feem ntau pib thiab nres, segmented lcd ntsej muag ob qho kev pheej hmoo loj: electrostatic tawm (ESD) thiab noo noo hws hws.
Electrostatic tso: lub zog hluav taws xob tsim tawm thaum lub zog ntawm / tawm tuaj yeem ncav cuag ob peb txhiab score, uas tuaj yeem nkag mus rau hauv polarizing zaj duab xis lossis cov neeg tsav tsheb ntawm ntu segmented lcd. Ib qho khoom siv Aerospace ntxiv ua kom muaj hluav taws xob nrog cov TVs ntawm cov pcb
Kev ntub dej hws: nquag pib nres tuaj yeem ua rau kub thiab noo kuab hloov mus rau saum npoo ntawm ntu LCD, ua rau cov hluav taws xob luv luv. Muaj qee yam kev tsim tshuaj ntsuam xyuas fluorine -} muaj cov tshuaj pov thawj ntawm 96, uas tau sim ua kom cov khoom pov thawj ntawm lub tsheb.
Txhim Kho Rau Lub Tswv Yim:
Esd tiv thaiv kev tsim qauv: Txuas ib qho 10k ω resistor thiab 100pf capacitor nyob rau ntu ntawm com / seg tus lej ntawm kev txhawb nqa lub siab {3.
Ya yafwb pov thawj encapsulation: laser vuam yog siv es tsis muaj kev ntxhov siab los txo cov dej nqus dej epoxy los txo cov dej nqus dej los ntawm 0.5% rau hauv qab 0.1%.
4, Kev Lag Luam Kev Lag Luam: Kev tswj lub neej ntawm cov khoom siv hluav taws xob hauv tsheb thiab cov khoom siv kho mob
1. Automotive electronics teb
Lub tsheb dashboard xav tau ua haujlwm ruaj khov nyob rau hauv ib puag ncig ntawm -40℃~ 85℃thiab dhau mus iso 16750 tsheb hluav taws xob thiab tshuab hluav taws xob ib puag ncig kev kuaj mob ib puag ncig. Ib qho kev ua haujlwm thoob ntiaj teb 1 tus neeg xa khoom txais cov phiaj xwm hauv qab no:
Cov khoom siv: Igzo electrode + fluorinated peb pov thawj pleev xim;
Txheej txheem: COG NTIM + ACF dav dav;
Kev Kuaj: Dhau ISO 16750 "Kev Ntsuas Ntsev Ntsev (240 teev tsis muaj corrosion) thiab iso 167℃mus kuaj (-40℃cycling (-40
2. Cov Khoom Siv Kho Mob
Lub olosimeter xav kom tau raws li IEC 60601-1 kev nyab xeeb qauv rau cov cuab yeej siv hluav taws xob, uas muaj kev tiv thaiv tsis zoo rau kev tiv thaiv corrosion. Daws los ntawm ib qho chaw tsim khoom:
Khoom siv: AZO electrode + Silicone encapsulation;
Txheej Txheem: Laser txiav hloov txhua yam txiav kom tshem tawm cov kev ntxhov siab tawg;
Kuaj: Kis qhov IEC 60068-2-11 teev tsis muaj kev corrosion) thiab IEC 60068-2-14 Vaum Kev Ntsuam Xyuas (95% RH, 1000 teev tsis ua haujlwm).
