一, qhov phom sij ntawm hluav taws xob zoo li qub rau ntu kev sib tw LCD: los ntawm kev puas tsuaj ntawm lub kaw lus kaw
1. Electrode sib tawg: ua rau tuag taus rau ito circuits
Cov qauv tso saib ntawm ntu LCD yog tsim ntawm pob tshab indium tin xide (iTo) electrate, nrog ib kab dav, nrog ib kab dav, nrog ib kab dav, nrog ib kab dav, nrog ib kab dav tshaj plaws ntawm 10}}}}}}}}}}}}} m. Lub intantaneous neeg voltage (nce rau ntau txhiab tus kaum ntawm ntau txhiab lub volts) thiab siab tam sim no tau tsim tawm tuaj yeem nkag ncaj qha rau kab kev, ua rau qhib kev ncig ua si lossis kev voj voog luv luv. Piv txwv li, thaum lub sij hawm debugging ntawm qee hom kev lag luam ntawm kev ua twj paj nruag, vim yog tus neeg tswj hwm tsis hnav ib qho kev tawm tsam dab teg, stroke (mob stroke) tsis tso tawm tom qab kov lub cev. Tom qab nrhiav tau, nws tau pom tias ITO electrode Circuit, thiab tag nrho cov qauv tshuaj ntsuam uas xav tau los hloov, nrog tus nqi nce mus txog 60% ntawm tus nqi thawj.
2. LCD Molecular Disorder: Lub hauv paus ua rau muaj cov khoom txawv txav
Lub pob hluav taws xob muaj zog tsim los ntawm kev tshem tawm electrostatic yuav cuam tshuam nrog lossis hloov kho cov kev ua kua ntawm cov kua lead ua kua crystal molecules. Cov kev sim tau qhia tias nyob rau hauv 8kV kev tso tawm, tshwm sim txawv, thiab kev ntxim nyiam, thiab kev ntxim nyiam, thiab qee qhov kev puas tsuaj yog tsis txaus ntseeg. Ib co photovoltaic inverter cov chaw tsim khoom tau tshaj tawm tias lawv cov lus qhia sab nraum zoov uas nquag pom cov duab hluav taws xob tsis zoo rau kev cuam tshuam rau kev tsis sib haum xeeb ntawm cov kua roj crystal molecules. Qhov teeb meem no yuav tsum tau daws los ntawm hloov lub cev screen.
3. Sealing Kua nplaum puas tsuaj: tsaus muag ntawm ib puag ncig kev yoog
Lub tshuab foob ntawm ntug ntawm segmented LCD yog siv los txiav lcd thiab cais nws ntawm huab cua, thiab cov hluav taws xob muaj zog yuav ua rau nws txoj kev ncaj ncees. Lub chaw tsim khoom siv cov khoom siv me me tau pom tias tom qab 150v cua tawm, LCD Takeage tau tshwm sim ntawm ntug ntawm lub vijtsam, ua rau lub vijtsam dub thiab npuas, thiab cov kab mob IP65, thiab cov roj av tiv thaiv tsis tau. Cov cuab yeej ua tiav tiav tom qab khiav hauv cov av nkos thiab dej ib puag ncig rau 2 teev.
4. Neeg tsav nti puas tsuaj: tus txhais rau txheej txheem theem kev ua yuam kev
Cov hluav taws xob zoo li cas tuaj yeem ua los ntawm cov pins ntawm lub vijtsam rau tus tsav lub nti ncaj ncaj ncaj ncaj rau lub khob. Thaum lub sij hawm debugging ntawm qee cov chaw tsheb ciav hlau thauj khoom, tag nrho cov pob ntawm cov neeg tsav tsheb sib tw tau raug kaw, ua rau muaj cov cim ntawm lub vijtsam. Nws thiaj li, cov chips xav tau xa rov qab mus rau lub Hoobkas rau kev hloov pauv, ua rau muaj hnub nyoog 15 hnub qeeb.
2, Kev Lag Luam Kev Lag Luam: Cov ntaub ntawv pov thawj nruj los ntawm kev kuaj cov chaw
1. Cov Txheej Txheem Thoob Ntiaj Teb: Cov Lus Qhia Rau IEC 61000-4-2
Qhov Kev Ntsuas Thoob Ntiaj Teb (IEC) tau tsim lub "Electromagnetic Sib Tw (EMC) ntu kev tiv thaiv kev tiv thaiv kev tiv thaiv" Txoj kev ntsuas muaj xws li:
Hu rau qhov tso tawm: Siv phom tawm kom tuaj cuag tau plaub fab thiab qhov chaw sib txuas ntawm lub cev screen, tsis tu ncua rau 10 zaug, saib xyuas cov zaub txawv txav thiab lub sijhawm rov qab.
Cov pa tawm: paug 10 zaug ntawm 4 fab thiab qhov chaw taw tes rau ntawm lub vijtsam sim anti {}}} sib cuam tshuam.
Tom qab dhau qhov kev xeem, qee cov hom phiaj ntawm cov vaj huam sib luag tiaj tiaj, ua pov thawj tias kev tiv thaiv kev ua yuam kev hauv cov ntsev ua ke tuaj yeem tsim kho ib puag ncig.
2. Kev Lag Luam Sab Hauv Tswj Tus Qauv: Tshaj Lij Choj Thoob Ntiaj Teb
Qee cov tuam txhab ua lag luam tau tsa lawv cov qib kev tiv thaiv kom siab dua. Piv txwv li, ib qho chaw tsim khoom Automotive cov cuab yeej siv tau kom muaj qhov sib txawv ntawm cov khoom siv nrog xyoo.
3, cov ntaub ntawv siv tau: cov lus qhia kev cai ntawm qhov tsis muaj kev tiv thaiv electrostatic
Rooj plaub 1: hluav taws teeb meem hauv cov tsev ua haujlwm
Hauv 2024, ib lub zoo {- noob npe semiconductor tuam txhab hauv HSICHCHU Science Park tau ua rau lub Hoobkas hluav taws vim yog electrostatic tawm. Raws li kev tshawb nrhiav, tus neeg teb xov tooj siv lub segd screen tsis muaj kev tawm tsam cov anti- cov khoom siv hluav taws xob zoo tshaj 50 lab Yuan. Qhov xwm txheej no tshoov qhov kev lag luam kom nkag siab zoo dua nws cov kev tswj hwm kev tswj hwm, suav nrog kev tswj hwm zoo li qub, nrog kev ua haujlwm zoo li qub, thiab hauv av ua.
Rooj plaub 2: Batch tsis ua hauj lwm ntawm them pawg cov ntxaij vab tshaus
Xyoo 2023, lub chaw nres tsheb thauj khoom lub terminals xa mus rau sab qaum teb thaj tsam feem ntau tso tawm cov cim garbled. Tom qab kev ntsuas, cov teeb meem tau pib los ntawm kev txuam nrog hluav taws xob zoo li qub nyob rau hauv lub caij ntuj no ib puag ncig (av noo<30%), and the screen did not use anti-static polarizing film. After replacing with anti-static materials, the failure rate decreased from 12% to 0.3%, and the annual maintenance cost was reduced by 800000 yuan.
4, Kev daws: Kev tiv thaiv tag nrho los ntawm kev tsim qauv los ua haujlwm thiab txij nkawm
1. Design theem: Txhim kho cov khoom siv thiab cov qauv
Phaj zaj yeeb yaj kiab xaiv: Siv cov ntaub ntawv nrog kev tiv thaiv siab - zoo li cov khoom siv pov tseg kom tsis txhob muaj puv npo cov ntawv nyeem. Qee hom npe txhim kho nws cov yeeb yaj kiab polarizing kom txo cov zaub tsis zoo los ntawm cov hluav taws xob tsis zoo los ntawm 5% rau 0.1%.
Cov qauv tsim qauv: Tsis txhob ntse fab thiab txo qhov kev pheej hmoo ntawm kev tawm ntawm qhov taub. Cov kev sim tau pom tias cov qauv electrode electrode electrode yuav txo qhov tshwm sim ntawm electrostatic tawg los ntawm 40%.
Esd kev tiv thaiv ntaus ntawv: Ntxiv cov voltage ntxiv kev ntsuas hluav taws xob diodes)
2. Cov theem ntau lawm: Kev tswj ntawm ib puag ncig thiab khoom siv
Vaum tswj: Cia cov av noo ntawm cov chaw tsim khoom ntawm 40%--60%% RH. Rau txhua 10% ntxiv rau hauv cov av noo, cov electrostatic muaj peev xwm txo tau los ntawm 50%. Qee cov chaw tsim khoom lag luam tau nce cov vijtsam zoo ntawm 85% mus rau 98% los ntawm cov txheej txheem avertification.
Khoom siv hauv av: tag nrho cov cuab yeej siv khoom siv, kev ua haujlwm, thiab kuaj cov khoom siv tsis muaj tsawg dua 1 ω kom ntseeg tau tias muaj hluav taws xob zoo li qub.
Anti zoo li qub ntim: Siv anti - Lub hnab ua npuas dej zoo li qub, thiab cov thawv ntim khoom kom tsis txhob muaj hluav taws xob zoo li qub.
3. Kev ua haujlwm thiab txij nkawm theem: qauv kev ua haujlwm ntawm kev ua haujlwm thiab txij nkawm
Cov neeg tiv thaiv cov neeg ua haujlwm: yuav tsum hnav cov tshuaj tiv thaiv kab mob, khaub ncaws, thiab tso cov hluav taws xob zoo li qub los ntawm kev kov cov hlau ua ntej kov lub cev.
Cov Qauv Tu: Nws txwv tsis pub siv cov tshuaj ntxuav lub tshuab nqus tsev (uas tuaj yeem tsim hluav taws xob hluav taws xob zoo nkauj), thiab es tsis txhob siv anti {{} zoo li cua txhuam lossis cua compressed rau tu.
Cia Kev Tswj Xyuas: lub vijtsam yog khaws cia hauv kev tiv thaiv hauv ove- zoo li qub lub hnab, nrog cov av noo tswj ntawm RH50% ± 5% thiab ntsuas kub ntawm 25℃±. 2 Qib.
