Kuv tau pom nws ntau zaus ntawm qhov chaw ua haujlwm, hauv tsev khaws khoom, lossis tawm hauv thaj chaw: ib tus neeg tso lub vijtsam kov lossis cov ntsiav tshuaj ua haujlwm los ntawm lub duav siab, thiab boom- npo tawg, kov tuag, lossis cov kab txawv txawv uas tua tag nrho kev ua haujlwm. Nws yog kev ntxhov siab, kim, thiab qee zaum txaus ntshai yog tias nws yog ib feem ntawm cov cuab yeej tseem ceeb.
Ntau qhov "rugged" TFT LCD saib no tuaj nrog cov ntawv thov zoo li "MIL-STD tau ntawv pov thawj" lossis "1.5m pov thawj," tab sis tom qab ntawd lawv ua tsis tiav hauv lub neej tiag tiag tom qab ob peb lub hlis. Yog li dab tsi tshwm sim thaum lub sij hawm sim poob? Cov qauv no txiav txim siab li cas yog tias qee yam tawv txaus? Thiab qhov tseem ceeb tshaj plaws, yog tias koj tab tom cuam tshuam nrog ib puag ncig ntxhib tiag tiag, vim li cas tawm -- cov khoom txee feem ntau tsis txaus- thiab yuav ua li cas rau kev cai nrog lub chaw tsim khoom LCD tuaj yeem kho cov teeb meem uas cov khoom lag luam tsuas yog ua tsis tau.
Thawj Yam Ua Ntej: Yuav Ua Li Cas Teev Kev Xeem Tiag Tiag
Yeej, qhov kev sim poob (lossis dawb- kuaj lub caij nplooj zeeg) yog qhov zoo li nws zoo li: koj cia lub cuab yeej poob ncaj nraim mus rau qhov chaw tawv tawv los ntawm qhov siab, feem ntau yog ntau zaus los ntawm ntau lub kaum sab xis (cov ces kaum, npoo, lub ntsej muag tiaj tus). Lub ntsiab lus yog los xyuas seb nws puas tseem ua haujlwm tom qab- tsis muaj iav tawg, tsis muaj qhov kov mus haywire, tsis muaj cov pob dub lossis flickering ntawm lub vijtsam, thiab tsis muaj kev puas tsuaj rau hauv qhov uas ua rau tsis ua tiav tom qab.
Nws txawv ntawm tsuas yog whacking nws nrog rauj vim hais tias lub zog los ntawm lub ntiajteb txawj nqus thiab ceev buildup. Tiag tiag tee tshwm sim sai thiab ntse -xav tias pua pua g- quab yuam crammed mus rau hauv ib tug sib cais thib ob.
Qhov kev sim no yog qhov zoo tshaj plaws rau kev lag luam TFT saib, vaj huam sib luag PCs, tswj kev sib tshuam hauv cov chaw tsim khoom, cov roj av, qhov chaw txias, lossis txhua qhov chaw iav tau khob txhua hnub.
Lub Physics: Vim Li Cas Tej Yam Tawg (thiab Yuav Ua Li Cas Lub Zog Tsiv)
Qhov yooj yim lej yog ncaj nraim: lub zog=mass × lub ntiajteb txawj nqus × qhov siab. Tso qee yam hnyav dua lossis siab dua, thiab qhov cuam tshuam tau zoo dua. Ceev ntawm tsoo hauv av? Nyob ib ncig ntawm 5-6 m / s los ntawm 1.5 meters-tsis vwm nrawm, tab sis lub deceleration thaum nws nres yog lim hiam.
Qhov kev poob siab no tua tag nrho pawg:
- Cov ntaub ntawv sab nrauv / plhaub siv thawj zaug
- Ces tus ncej
- Txhua qhov sib txawv ntawm huab cua lossis txheej nplaum
- Lub khob iav
- Kov sensor txheej (feem ntau yog ITO lossis zoo sib xws cov kab hluav taws xob)
- Thaum kawg lub LCD vaj huam sib luag nws tus kheej, ntxiv rau cables thiab boards
iav yog qhov txuas tsis muaj zog vim nws nkig. Ib qho zoo khoov los yog twist, thiab cov kab nrib pleb me me kis tau zoo li xob laim (uas yog qhov tawg ntawm kev nthuav dav cov kws tsim txuj ci hais txog). Ntug yog qhov yooj yim dua vim tias muaj kev ntxhov siab nyob rau ntawd.
Tej yam uas nws ua tsis tau:
- Iav shatters los yog kab laug sab webs
- Kov cov kab nrib pleb → qhov chaw tuag lossis drifting
- Cov khaubncaws sab nraud povtseg LCD hloov pauv → qhov tsis zoo, cov teeb meem xim, lossis tag nrho cov blackout
- Adhesive cia mus → kov xav tias tawm los yog npuas tshwm
Cov khoom uas ua rau nws tsis zoo: txias temps (iav tau nkig ntau), tawv tawv zoo li pob zeb vs softer plywood, los yog qhov poob hits lub ces kaum tsis tiaj tus.
Cov Qauv Tseem Ceeb Cov neeg siv tiag tiag
Nov yog cov loj loj uas koj yuav pom tau hais:
- MIL-STD-810H Txoj Kev 516(cov tub rog nyiam rau cov iav rugged): Feem ntau 1.2-1.5 meters (kwv yees 4-5 ko taw), 26 tee npog txhua lub ces kaum, ntug, thiab lub ntsej muag. Nto yog feem ntau plywood tshaj pob zeb. Yuav kom dhau: txhua yam tseem ua haujlwm zoo kawg nkaus - tsis muaj kab nrib pleb hauv iav, kov qhov tseeb, tso saib kom huv (ob peb khawb ntawm lub cev zoo).
- IEC 60068-2-32: Cov: Ntau yam yooj yim dua - khoom poob, feem ntau siv rau cov khoom siv hluav taws xob.
- Txhua hnub kev lag luam specs: 1.5–1.8m tee, 30–50+ zaug ntawm pob zeb, cia siab tias yuav tsis kov drift lossis tuag pixels.
- Kev ua haujlwm nyuaj heev: 2m + tee rau cov hlau, 50-100 cycles, xoom pom kev puas tsuaj.
Cov lus nrawm rau kev sib piv:
| Txuj | Qhov siab | Poob/Angles | Nto | Dab tsi "Pass" txhais tau tias |
|---|---|---|---|---|
| MIL-STD-810H | 1.2–1.5 m | 26 (tag nrho cov kev taw qhia) | Plywood + pob zeb | Ua haujlwm puv, tsis muaj iav tawg, kov / tso saib OK |
| Hom Kev Lag Luam | 1.5–1.8 m | 30–50+ | Pob zeb | Tsis muaj kab nrib pleb, tsis muaj teeb meem kov, tsis muaj qhov tsis xws luag |
| Heev / Kev Cai | 2 m+ | 50–100+ | Hlau / pob zeb | Zero tawg + kov nyob twj ywm meej |
Feem ntau TFT LCD cov khoom lag luam sau cov ntsiab lus 1.5m, tab sis lawv tsis tshua hais txog kev ua tag nrho 26 kev taw qhia lossis kev sim ntawm huab cua txias.
Yog vim li cas Standard Screens Pass Test tab sis tseem tawg nyob rau hauv lub ntiaj teb no tiag
Ntau cov generic TFT LCD saib siv tib lub iav nyias (0.7-1.1mm), yooj yim ntxiv dag zog, thiab feem ntau yog qhov sib txawv ntawm huab cua ntawm kov thiab tso saib. Lawv nyem los ntawm cov ntawv pov thawj kom txo cov nqi, tab sis lawv tsoo cov kev txwv ceev ceev hauv qhov chaw hnyav dua -xws li poob los ntawm qhov siab dua, hauv qhov txias txias, lossis nrog qhov hnyav ntxiv / vibration.
Qhov ntawd yog qhov uas koj pib pom kev rov qab los, kev poob qis, thiab kev npau taws hu los ntawm thaj teb.
Yuav ua li cas kev cai LCD hloov qhov kev ua si tiav
Qhov no yog kev ncaj ncees qhov twg cov khawv koob tshwm sim. Raws li cov chaw tsim khoom tshwj xeeb LCD zaub thiab cov chaw tsim khoom siv LCD, peb tsis yog sib sau ua ke tawm ntawm -- txee qhov chaw- peb tsim tag nrho pawg los ntawm iav.
Peb tuaj yeem ua qhov txawv:
- Siv cov iav tuab, tshuaj ntxiv dag zog (xws li aluminosilicate) nrog cov ntug tshwj xeeb shaping kom tsis txhob tawg ua ntej lawv pib.
- Kev sib txuas kho qhov muag tag nrho: nplaum qhov kov, iav, thiab LCD ua ke nrog cov nplaum ntshiab - tsis muaj qhov sib txawv ntawm huab cua. Qhov no kis tau qhov kev poob siab sib npaug, txhawb kev cuam tshuam kev tiv thaiv ib tuj (feem ntau 30-50% lossis ntau dua), txiav kev puas tsuaj, thiab ua kom cov plua plav / dej tawm.
- Hloov mus rau cov khoom siv tawv tawv (hlau mesh lossis nano- cov kab nyiaj tsis yog ITO tsis yooj yim) yog li lawv flex tsis tawg.
- Ntxiv cov kev cai buffers xws li ua npuas ncauj los yog silicone txheej hauv lub thav duab kom ntub cov peak force.
- Tsim kom muaj kev vwm: poob ntawm -40℃rau +85℃, 2m+ rau cov hlau tsis muaj kab nrib pleb, lossis ntau pua lub voj voog yam tsis poob qhov tseeb.
Peb tau ua qhov project qhov twg:
- Ib chav tsev roj av ciaj sia 50 tee los ntawm 2m mus rau steel -kov nyob twj ywm zoo meej.
- Txias-chain iav tuav -35℃poob los ntawm 1.8m-tsis muaj hluav taws xob lossis tsis ua haujlwm.
- Cov ntxaij vab tshaus mining tau hnyav vibration + rov qab khob- teb tsis ua hauj lwm tus nqi poob yuav luag rau xoom.
Cov khoom txheem tau txais koj "zoo txaus rau daim ntawv spec." Kev cai tau txais koj ib yam dab tsi uas muaj sia nyob koj qhov npau suav phem txhua hnub.
Wrapping It Up
Thaum koj nkag siab tias qhov kev xeem poob tiag tiag ua haujlwm li cas- lub zog, cov ntsiab lus tsis ua haujlwm, cov qauv- koj tsis txhob yuav raws li hype thiab pib nug cov lus nug raug. Thiab yog tias koj daim ntawv thov yog qhov phem tiag tiag, cov lus teb yog yuav luag ib txwm ua kev cai engineering.
NtawmMinghua zaub,qhov ntawd yog qhov peb ua. Peb yog ib lub chaw tsim khoom siv LCD, kev cai LCD chaw tsim khoom, thiab kev ntseeg siab TFT LCD tus neeg muag khoom tshwj xeeb hauv rugged TFT LCD saib, siab -hloov touchscreen modules, kho qhov muag sib txuas, thiab ua kom pom zoo rau kev lag luam, sab nraum zoov, thiab qhov chaw hnyav.
Tau txais ib qhov project uas xav tau kev poob qis, qhov kub thiab txias, lossis lwm yam kev xav tau nyuaj? Tua peb cov lus nrog "Kev Cai LCD" hauv cov ntsiab lus -peb yuav muab ncaj qha rau koj - kev sib tham, sib qhia cov ntaub ntawv xeem, lossis txawm thuam tus qauv los ua pov thawj tias nws ua haujlwm hauv koj lub ntiaj teb.
Cia peb paub tseeb tias koj cov zaub tom ntej tsis yog dhau qhov kev sim- nws nyob qhov twg nws tseem ceeb.
Minghua Display – Koj mus-rau kev koom tes rau kev cai, tsis muaj kev daws teeb meem LCD.
