LCD splicing npo yog ib qho ntawm cov khoom nrov tshaj plaws uas nyiam los ntawm cov neeg siv. Lub LCD splicing phab ntsa tsim los ntawm splicing cov ntxaij vab tshaus yuav ntsib cov duab tsis meej hauv kev ua haujlwm tiag tiag, thaum daim duab ntawm LCD splicing screen tsis meej. : Tsawg brightness, tsis zoo ntug tsom, ghosting (duab smearing), cuam tshuam fringe stacking (lub teeb liab qhov kev daws teeb meem siab dhau lawm) los yog duab jagged (poob thav duab), LCD mosaic phab ntsa tsis screen zaub (tsis muaj teeb liab screen zaub)), thiab lwm yam. , thaum qhov tshwm sim saum toj no tshwm sim, yuav ua li cas cov neeg saib xyuas yuav ua li cas debug lub LCD splicing phab ntsa?
Lub splicing screen phab ntsa qhia txog xiav hauv qab:
Ua ntej ntawm tag nrho cov, koj yuav tsum to taub yog vim li cas lub mosaic screen qhia ib tug xiav tom qab? Txawm hais tias tag nrho cov phab ntsa spliced screen los yog ib qho screen spliced nkaus xwb qhia txog keeb kwm xiav, nws txhais tau tias tsis muaj teeb liab. Yog li ntawd, thaum ib qho screen nkaus xwb qhia txog xiav keeb kwm yav dhau, nws yuav yog qhov teeb tsa software, lub teeb liab processor rau lub vijtsam teeb liab kab interface yog xoob lossis kab tsis zoo, xyuas seb qhov cuam tshuam puas xoob, lossis hloov kab kuaj. Thaum tag nrho cov phab ntsa splicing yog xiav lossis ntau cov ntxaij vab tshaus tso saib xiav hauv qab, qhov teeb meem yuav yog qhov teeb meem ntawm lub teeb liab processor thiab cov teeb liab tso zis ntaus ntawv, thiab qhov thib ob yuav yog qhov tsis zoo ntawm cov teeb liab cable thiab lub interface. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau xyuas cov software nqis, teeb liab processor, teeb liab tso zis ntaus ntawv, teeb liab interface, teeb liab kab kom txog rau thaum koj pom qhov teeb meem.
Dub screen ntawm splicing screen phab ntsa:
Lub vijtsam dub ntawm lub vijtsam LCD splicing tuaj yeem tshwm sim los ntawm cov teeb meem hauv qab no: qhov teeb tsa tsis raug ntawm cov software splicing tsis raug, tus tsav tsheb ntawm lub vijtsam splicing puas lawm, lub vijtsam LCD puas lawm, thiab lub hwj chim board puas lawm. Peb xyuas raws li plaub lub ntsiab lus no, lub vijtsam dub ntawm lub vijtsam splicing yuav tsis muaj zog, lossis lub vijtsam splicing yuav raug kaw los ntawm software lossis chaw taws teeb tswj kom tshem tawm cov khoom puas.
Debug LCD npo duab tso saib xwm txheej tsis paub:
Ua ntej tshaj plaws, koj tuaj yeem ua qhov teeb meem: lub LCD splicing phab ntsa tuaj yeem segmented thiab tshuaj xyuas, thiab qhov teeb meem tuaj yeem pom. Koj tuaj yeem tshawb xyuas seb qhov kev daws teeb meem ntawm LCD splicing phab ntsa teeb liab qhov twg yog raws li qhov kev daws teeb meem ntawm lub davhlau ya nyob twg. Yog tias nws yog lub teeb liab video, nws nyob ntawm seb lub kaw lus tuaj yeem tso saib lub davhlau ya nyob twg. Yog tias nws tsis ua tau raws li qhov yuav tsum tau ua ntawm lub davhlau ya nyob twg, qhov xwm txheej ntawm lub teeb liab tuaj yeem hloov pauv los ntawm kev hloov khoom siv lossis ntxiv cov khoom siv hloov pauv.
Qhov thib ob, saib seb qhov bandwidth ntawm splitter thiab matrix switcher thiab nws impedance rau lub teeb liab tuaj yeem txo cov duab poob nyob rau hauv cov qauv kev ncua deb. Thaum kawg, xyuas seb qhov ua kom pom tseeb thiab kev sib koom ua ke ntawm cov khoom siv pom zoo li cas, thiab seb lub teeb liab ua haujlwm puas zoo.
Tsis tas li ntawd, yog tias cov duab ntawm lub LCD video phab ntsa yog phantom, koj yuav tsum tau xyuas seb lub kis tau tus mob cable ntev dhau lawm los yog nyias. Txoj kev daws teeb meem yog hloov cov kab lossis ntxiv cov teeb liab amplifiers thiab lwm yam khoom siv. Yog tias qhov kev tsom xam tsis zoo, koj tuaj yeem kho lub davhlau ya nyob twg thiab lwm yam.
