I. Lub hauv paus ntsiab lus ntawm LCD
Cov kua siv lead ua kua
Lub vijtsam zoo li tsuas yog ib qho screen xwb, qhov tseeb, nws tsuas yog tsim los ntawm plaub daim loj (filter, polarizer, iav, txias cathode fluorescent teeb), ntawm no los qhia koj cov lus piav qhia luv luv.
Lim: vim li cas TFT LCD vaj huam sib luag tuaj yeem tsim cov xim hloov yog feem ntau los ntawm cov xim lim.Lub vaj huam sib luag hu ua kua siv lead ua kua tuaj yeem ua kua siv lead ua kua molecules sawv hauv kab los ntawm kev hloov hluav taws xob ntawm kev tsav tsheb IC, thiaj li ua kom pom cov duab.Daim duab nws tus kheej yog xim dub thiab dawb, thiab tuaj yeem hloov mus rau xim qauv los ntawm cov lim.
Polarizing phaj: polarizing phaj tuaj yeem hloov lub teeb ntuj mus rau hauv cov ntsiab lus polarizing, nws qhov kev ua tau zoo yog cais cov khoom tawm los nrog cov polarizing Cheebtsam, ib feem yog ua kom nws dhau, lwm qhov yog nqus, xav txog, tawg thiab lwm yam ua rau nws. zais cia, txo cov tiam ntawm cov ntsiab lus ci / phem.
Txias cathode fluorescent teeb: nws yog tus cwj pwm los ntawm lub ntim me me, siab ci thiab lub neej ntev.Ua los ntawm cov iav tshwj xeeb tsim thiab ua tiav, lub teeb txias cathode fluorescent tuaj yeem siv ntau zaus tom qab teeb pom kev zoo thiab tuaj yeem tiv taus txog li 30,000 kev hloov pauv.Vim tias txias cathode fluorescent. Lub teeb siv peb-xim phosphor hmoov, yog li nws cov luminous siv zog nce, lub teeb poob qis, xim kub ua haujlwm tau zoo, yog li ua rau cov cua sov kom muaj nuj nqis tsawg heev, tiv thaiv peb cov kua siv lead ua kua ua lub neej.
Ua rau thiab tiv thaiv qhov kaj / qhov tsis zoo ntawm cov kua siv lead ua kua
1. Yog vim li cas ntawm cov chaw tsim khoom:
Qhov kaj / qhov tsis zoo kuj tseem hu ua qhov kaj ntawm LCD, uas yog hom kev puas tsuaj ntawm lub cev ntawm LCD.Nws yog tsuas yog tshwm sim los ntawm sab nraud quab yuam compression los yog me ntsis deformation ntawm lub sab hauv reflection phaj ntawm lub ci qhov chaw.
Txhua pixel ntawm lub vijtsam LCD muaj peb lub ntsiab xim, liab, ntsuab thiab xiav, uas ua ke los tsim ntau yam xim.Ua 15-nti LCD ua piv txwv, nws thaj tsam LCD yog 304.1mm * 228.1mm, daws teeb meem yog 1024 * 768, thiab txhua lub LCD pixel yog tsim los ntawm RGB thawj xim chav tsev.Liquid crystal pixels yog "kua siv lead ua thawv" tsim los ntawm pouring kua siv lead ua rau hauv pwm ruaj.Tus naj npawb ntawm cov "kua siv lead ua kua" ntawm 15-nti LCD zaub yog 1024 * 768 * 3 = 2.35 lab!Dab tsi yog qhov loj ntawm lub thawv LCD?Peb tuaj yeem xam tau yooj yim: qhov siab = 0.297mm, dav = 0.297/3 = 0.099mm! Hauv lwm lo lus, 2.35 lab "kua siv lead ua lub thawv" nrog thaj tsam ntawm tsuas yog 0.297mm * 0.099mm yog teem kom ntom ntom hauv thaj tsam ntawm 304.1mm * 228.1mm, thiab lub raj tsav uas tsav lub thawv kua siv lead ua yog kev sib xyaw ua ke. Tom qab cov kua siv lead ua kua lub thawv.Ntawm qhov tseeb, cov txheej txheem tsim khoom yuav tsum tau ua ntawm cov kab ntau lawm, ntawm cov cuab yeej siv tam sim no thiab cov khoom siv tes ua, kuj tsis tuaj yeem lav tias txhua batch tsim LCD npo tsis ci / cov ntsiab lus tsis zoo, cov tuam txhab feem ntau tsis txhob ci / tsis zoo rau ntu LCD vaj huam sib luag, tsis muaj cov ntsiab lus ci / tsis zoo lossis tsawg qhov kaj / tsis zoo LCD vaj huam sib luag ntawm cov khoom lag luam siab muaj zog, thiab cov teeb pom kev zoo / cov ntsiab lus tsis zoo ntau lub vijtsam LCD feem ntau yog cov khoom me me hauv kev tsim cov LCD pheej yig.
Technically, lub teeb ci / qhov tsis zoo yog qhov tsis tuaj yeem hloov pauv pixel ntawm LCD vaj huam sib luag uas tau tsim thaum lub sijhawm tsim khoom.Lub LCD vaj huam sib luag yog tsim los ntawm cov kua siv lead ua kua pixels ruaj khov, txhua tus uas muaj peb lub transistors sib xws rau cov lim liab, ntsuab thiab xiav tom qab. 0.099mm kua siv lead ua pixel
Lub faulty transistor los yog luv luv Circuit Court ua rau lub pixel no ib tug kaj / phem point.Ntxiv rau, txhua LCD pixel kuj integrated qab ib tug nyias tsav tsheb raj tsav nws.Yog hais tias ib los yog ntau tshaj ntawm cov xim liab, ntsuab thiab xiav thawj xim tsis, lub pixel. tsis tuaj yeem hloov xim ib txwm thiab yuav dhau los ua cov xim ruaj khov, uas yuav pom meej meej hauv qee cov xim tom qab.Qhov no yog qhov ci ntsa iab / qhov tsis zoo ntawm LCD.Bright / qhov chaw tsis zoo yog ib hom kev puas tsuaj rau lub cev uas tsis tuaj yeem zam tau 100% hauv kev tsim khoom thiab kev siv lub vijtsam LCD.Feem ntau, nws yog tsim nyob rau hauv lub manufacturing ntawm lub screen.Raws li ntev raws li ib los yog ntau tshaj ntawm cov thawj xim uas ua ib tug ib pixel puas lawm, ci / phem me ntsis generated, thiab ntau lawm thiab siv yuav ua rau puas.
Raws li lub rooj sib tham thoob ntiaj teb, cov kua siv lead ua kua muaj 3 hauv qab lub teeb ci / qhov tsis zoo yog nyob rau hauv ntau yam uas tau tso cai, txawm li cas los xij cov neeg siv khoom tsis zoo li yuav txaus siab yuav lub monitor uas muaj qhov ci / qhov tsis zoo thaum yuav cov kua siv lead ua kua, yog li cov khoom siv lead ua kua. uas muaj qhov ci ntsa iab / qhov tsis zoo feem ntau muag nyuaj heev.Yuav ua li cas cov tuam txhab ua vaj huam sib luag cuam tshuam nrog peb lossis ntau dua qhov ci / qhov tsis zoo vim yog cov txheej txheem tsim khoom?Raws li kom tau txais txiaj ntsig, qee cov tuam txhab yuav tsis rhuav tshem cov ntxaij LCD no, thiab feem ntau, lawv yuav siv cov cuab yeej tshaj lij los kho qhov tsis zoo / qhov tsis zoo, kom ua tiav cov txiaj ntsig tsis muaj qhov tsis zoo / qhov tsis zoo ntawm qhov chaw mus rau qhov muag liab qab.Ib ob peb lub tuam txhab tsis txawm ua cov txheej txheem, ncaj qha muab cov panels rau hauv cov kab ntau lawm. rau ntau lawm, thiaj li ua tiav lub hom phiaj ntawm kev txo cov nqi.Cov khoom no muaj qhov zoo ntawm tus nqi, tab sis nws yuav tsim qhov ci / tsis zoo tom qab siv.Tam sim no ntawm kev ua lag luam ntau cov khoom siv hluav taws xob pheej yig yog li ntawd.ua tiav, yog li koj tsis xav yuav cov kua siv lead ua kua zaub pheej yig, mus yuav qee yam tsis paub npe.Zoo siab yuav tus nqi qis - tsis muaj - ci zaub.Vim tias tom qab ib ntus, yam koj tsis xav pom yuav tshwm sim thaum kawg.
2. Yog vim li cas siv
Qee qhov LCD ci ntsa iab / cov ntsiab lus tsis zoo yuav tshwm sim los ntawm kev siv cov txheej txheem, tsuas yog qhia koj txog kev siv qee qhov kev ceev faj:
(1) Tsis txhob nruab ntau lub tshuab tib lub sijhawm; Kev teeb tsa ntau lub tshuab hauv cov txheej txheem hloov pauv yuav ua rau qee qhov kev puas tsuaj rau LCD.
(2) ua kom lub zog thiab lub zog zoo li qub;
(3) tsis txhob kov lub khawm LCD txhua lub sijhawm.
Tag nrho peb yam no ncaj qha lossis ncaj qha cuam tshuam rau kev ua haujlwm ib txwm ua ntawm "kua siv lead ua lub thawv" molecules, uas tuaj yeem ua rau kev tsim cov ntsiab lus ci / tsis zoo. los ntawm kev soj ntsuam ntawm engineers.Txawm tias qhov kaj / qhov tsis zoo ntawm cov neeg siv khoom tuaj yeem nkag siab yog tias cov neeg tsim khoom tsis ua mob rau cov neeg siv khoom yam tsis muaj lub siab xav.
Lub teb chaws tus qauv yog 335, txhais tau hais tias peb lub teeb ci, lossis peb qhov tsaus nti, tsim nyog raws li qhov qub.
