kev taw qhia
Vim tias qhov cuam tshuam ntawm STN hom kua siv lead ua kua zaub module, qee zaum koj yuav pom qhov tshwm sim zoo li no thaum kuaj: thaum tso tawm cov ntsiab lus, yog tias muaj ntau cov duab cuam tshuam tshwm sim rau ntawm ib kab ntawv, ces kab ntawv no cov zaub ntawm cov pixels ntxiv yuav yog. sib dua li cov zaub ntawm pixels nyob rau hauv lwm qhov chaw uas tsis yog-ntsia, thiab ntau pixels tso tawm nyob rau hauv kab no, lub lighter cov zaub ntawm lwm pixels nyob rau hauv kem no yuav yog, thiab tag nrho cov saib yuav yog ib tug los ntawm ib tug. Vertical tuav yog pom tseeb heev. Peb tau ua ib qho kev ntsuam xyuas thiab kev sim rau cov xwm txheej zoo li no.
1 Kev sim txheej txheem
Ua ntej ntawm tag nrho cov, peb yuav tsum tshem tawm cov COG modules nrog loj ntsug tuav thiab ICs ntawm tib cov khoom modules tsis muaj ntsug tuav. Ntsuam xyuas qhov tsis muaj electro-optical, thiab koj yuav pom tias qhov sib txawv nkhaus ntau nrog cov kab ntsug yog qhov nqaim dua. Nws tsuas yog hais txog 1V. Sab laug thiab sab xis, thiab qhov sib piv ntau yam tsis muaj kab ntsug yog qhov dav, ncav cuag 3V. Nyob rau tib lub sijhawm, ib qho ntawm lawv cov kev siv hluav taws xob tam sim no tau sim, thiab nws tau pom tias lub zog siv tam sim no nrog cov kab ntsug ntau dua yog qhov loj, thiab lub zog siv tam sim no tsis muaj cov kab ntsug yog me me.
Tom qab tshawb pom txoj cai no, txhawm rau thim rov qab qhov kev lees paub, tib yam khoom raug rub tawm, thiab tom qab ntawd muab faib ua ob pawg raws li kev siv hluav taws xob tam sim no. Qhov sib txawv ntau yam uas siv ntau tam sim no yog qhov nqaim dua.
Peb tau ua qhov kev sim los ntawm qhov kev xav ntawm IC dua. Cov ntxaij vab tshaus LCD ntawm tib tus qauv tsim thiab thev naus laus zis siv cov IC sib txawv, thiab peb pom tias kev siv cov kab sib txawv IC ntsug sib txawv. Qee qhov pom tseeb, thiab qee qhov tsis pom tseeb. Tsis yog, yog vim li cas: txawv ICs muaj peev xwm tsav sib txawv, thiab cov kab ntsug nrog lub peev xwm tsav tsis zoo yuav hnyav dua.
2 ua rau kev tsom xam
Dot-matrix LCD cov ntxaij vab tshaus feem ntau siv txoj hauv kev tsav tsheb. Feem ntau, kab electrodes yog scanning electrodes, thiab qhov voltage ntawm ib tug series ntawm scanning pulses yog siv nyob rau hauv kev txiav txim ntawm lub sij hawm. Cov kab hluav taws xob feem ntau yog qhov chaw nyob electrode, uas yuav tsum tau synchronized nrog lub scan voltage thiab input lub rooj vag voltage waveform thiab lub non-gate voltage waveform feem. Nyob rau lub sijhawm thaum ob tog nkag mus rau qhov tsav tsheb voltage waveform tib lub sijhawm, lawv yuav ua rau lub zog tsav tsheb ntawm kev sib tshuam ntawm kab thiab kab. Pixels synthesized rau hauv gated waveform yog tshwm sim, thiab pixels synthesized rau hauv ib tug non-gated waveform tsis tshwm sim. Txawm li cas los xij, txij li thaum yuav muaj qee qhov hluav taws xob ntawm qhov tsis pom qhov taw qhia, kuj tseem yuav muaj qhov muag tsis pom ntawm qhov tsis pom qhov taw tes, uas yog, qee qhov keeb kwm dub yuav tshwm sim. Cov kab scan electrodes yog cyclically scanned thiab tsis muaj dab tsi ua nrog cov ntsiab lus tso tawm, tab sis cov kab hluav taws xob yog strobed electrodes thiab muaj feem xyuam rau cov ntsiab lus tso tawm. Lub teeb liab nyob rau hauv kem qhov twg lub gated point nyob yog txawv los ntawm cov kem uas tsis yog-gated point nyob. Thaum lub zog siv tam sim no ntawm lub vijtsam LCD loj dhau los yog lub peev xwm tsav tsheb ntawm IC tsawg dhau, cov kab ntsug yuav tshwm sim.
Kev daws
Kev siv IC nrog lub peev xwm tsav tsheb muaj zog yuav tsis ntseeg ncaj qha txo txoj hauv kev ntawm txoj kab ntsug, tab sis qhov no yuav ua rau tus nqi nce ntau, thiab txo qis kev siv hluav taws xob thiab tam sim no ntawm lub vijtsam LCD yog undoubtedly ib txoj kev ua tau thiab kev lag luam heev. Yog li dab tsi yog qhov cuam tshuam nrog kev siv hluav taws xob tam sim no? Los ntawm qhov kev xav ntawm lub vijtsam LCD, daim ntawv tsis kam ntawm ITO iav thiab cov conductivity ntawm cov kua siv lead ua kua yog ob yam tseem ceeb tshaj plaws. Peb kuj tau ua ib qho kev sim me me ntawm qhov no, hloov 20 ohm iav nrog 15 ohm iav, thiab siv cov kua siv lead ua qub thiab cov kua siv lead ua tshiab uas tau muab sib xyaw rau ntau zaus los ua qhov kev sim orthogonal. Cov txiaj ntsig kev sim tau pom meej meej tias qhov kev siv hluav taws xob tam sim no ntawm qhov me me square kuj thiab cov kua siv lead ua tshiab yog qhov me dua li cov kua siv lead ua qub qub thiab cov square loj tsis kam. Tsis tas li ntawd, thaum kos duab, nws yog ib qho tsim nyog yuav tsum tau ua kom cov kab ntau npaum li qhov ua tau, nce qhov kev faib ua feem ntawm cov hmoov kub conductive, txhim kho qhov tseeb ntawm kev sib dhos, thiab ntxuav qhov sib txawv ntawm electrode, thiab lwm yam, uas yog txhua txoj hauv kev kom txo tau lub zog. kev siv tam sim no. Tsis tas li ntawd, los ntawm qhov kev xav ntawm cov txheej txheem ntawm lub module, kom ntseeg tau qhov tseeb ntawm nws cov electrode kev sib raug zoo, tswj cov txheej txheem thiab kev faib ua feem ntawm lub pob crushing, thiab lwm yam kuj tuaj yeem txo qhov kev siv hluav taws xob ntawm Circuit Court.
Hauv cov ntsiab lus, yog tias koj xav tshem tawm qhov tshwm sim ntawm cov kab ntsug, qhov tseem ceeb yog xaiv ib qho IC uas muaj peev xwm tsav tau zoo dua thiab txo cov kev siv hluav taws xob tam sim no ntawm tag nrho cov qauv, kom ob qho tib si tuaj yeem ua tau zoo. Nyob rau tib lub sijhawm, peb tseem tab tom kawm qee txoj hauv kev los txhim kho cov kab ntsug, xws li kho cov polarizer, txo qhov hluav taws xob los ua kom lub ntsej muag sib dua, thiab lwm yam, tsis tuaj yeem daws qhov teeb meem hauv paus, tab sis nws tseem yuav txo qhov tshwm sim, uas kuj yog ib txoj kev zoo dua.
