Puas yog lub teeb pom kev zoo ib yam li lub teeb pom kev zoo?
Sep 17, 2021
Back Light Unit (Back Light Unit) yog tus muab cov kua siv ua kua (LCD) lub teeb ci. LCD nws tus kheej tsis tso tawm lub teeb. Kev ua tau zoo ntawm lub teeb pom kev ntawm lub teeb pom kev zoo rov qab txiav txim siab qhov pom kev pom ntawm cov zaub. Cov kua siv lead ua kua yog lub teeb thiab lub teeb vim lawv cov tuab tuab. Ntxiv mus, nws yog ib qho yooj yim nqa, thiab qhov kev thov tau nce sai heev nyob rau xyoo tas los no, thiab nws muaj peev xwm nyob hauv ib qho chaw hauv CRT kev lag luam.
Tus qauv ntawm lub teeb pom kev zoo rov qab, teeb pom kev zoo teeb (teeb, LED lossis EL thiab lwm yam) Lub Teeb Qhia Phaj (Teeb Qhia Phaj) Reflector (Reflector) Prism sheet (prism sheet). Teeb tsom teeb (teeb tsom teeb) Txheej sab nrauv.
Dab tsi yog backlight module? Nws siv rau dab tsi?
Lub Teeb Pom Kev Rov Qab yog ib qho tseem ceeb ntawm LCD Vaj Huam Sib Luag. Txij li cov kua siv lead ua nws tus kheej tsis muaj cov yam ntxwv zoo nkauj, lub teeb pom kev yuav tsum tau ntxiv rau hauv qab ntawm LCD vaj huam sib luag kom ua tiav cov xim puv xim. Raws li qhov tshwm sim, qhov ua haujlwm ntawm lub teeb pom kev zoo rov qab yog muab lub teeb pom kev txaus thiab faib cov phiaj xwm teeb pom kev zoo ib yam, yog li ntawd LCD tuaj yeem tso saib cov duab ib txwm muaj.
Tam sim no, cov khoom lag luam tseem ceeb ntawm cov teeb pom kev zoo suav nrog: lub teeb pom kev tawm ntawm lub teeb (LED), lub teeb tungsten halogen, electroluminescence (ELD), txias cathode fluorescent teeb (CCFL), cathode emitting teeb (CLL), thiab cov hlau halide teeb.
Ntawm lawv, thev naus laus zis tau paub tab thiab kev ua haujlwm tau ruaj khov. Cov teeb pom kev rov qab siv feem ntau ntawm cov xim kua siv lead ua kua (TFT-LCD) yog txias cathode fluorescent teeb (CCFL); LED qhov chaw teeb pom kev zoo feem ntau siv ntawm LCDs nrog thaj chaw me me, tshwj xeeb tshaj yog rau teeb pom kev zoo ib yam. Cov teeb pom kev zoo sab nraub qaum yog lub hauv paus tseem ceeb, thiab LED teeb pom kev zoo feem ntau yog siv hauv LCD cov vaj huam sib luag xws li xov tooj ntawm tes, PDAs, game consoles, khoom siv hauv tsev, ntsuas, ntsuas, khoom siv digital, khoom siv hauv tsheb thiab lwm yam khoom lag luam.
Dab tsi yog qhov backlight module?
LCD kua siv lead ua kua zaub yog lub npe luv ntawm Liquid Crystal Display. Cov qauv ntawm LCD yog tso cov kua ua kua hauv ob daim iav ua ke. Muaj ntau txoj kab ntsug thiab kab rov tav me me ntawm ob daim iav. Cov pas nrig zoo li tus qauv siv lead ua yog tswj los ntawm kev siv hluav taws xob lossis tsis siv. Hloov cov kev taw qhia thiab thim lub teeb kom tsim daim duab.
LCM kua siv lead ua kua zaub module yog ib feem uas sib sau ua ke cov khoom siv ua kua siv lead ua kua, cov khoom sib txuas, cov khoom siv sib txuas, PCB Circuit board, cov teeb pom kev rov qab, thiab cov khoom tsim. Lub npe Askiv yog&& quot; LCD Module&& quot;, sau luv ua&& quot; LCM", thiab nws feem ntau hu ua Suav&& quot; LCD Module&& quot; .
Qhov tseeb, nws yog hom khoom lag luam tivthaiv. Raws li cov txheej txheem hauv tebchaws tseem ceeb ntawm peb lub tebchaws, tsuas yog cov khoom sib xyaw ua ke sib cais tsis tau hu ua&"modules &";
Yog li ntawd, tus qauv lub npe yuav tsum raug hu ua&"; kua siv lead ua kua sib dhos &".
Tab sis vim tias tib neeg tau siv los hu nws" module" ntev lawm.
Ntawd yog hais, qhov sib txawv ntawm lcd thiab lcm tuaj yeem kos, yog li qhov sib txawv ntawm lcd thiab lcm: lcd yog lub vijtsam zaub, lcm yog sau los ntawm ntau yam khoom siv suav nrog lcd thiab tswj lcd zaub hom thiab cov ntsiab lus, xws li chips thiab Circuit Board.
Nws tuaj yeem hais tias lcd yog lub rooj ua ntej rau tso saib cov ntsiab lus, thiab lcm yog tag nrho cov txheej txheem ua haujlwm suav nrog lub rooj ua ntej.
Dab tsi yog qhov backlight module?
Lub hauv paus tseem ceeb ntawm cov kua siv lead ua kua yog cov kua siv lead ua kua, thiab cov khoom tseem ceeb ntawm cov kua siv lead ua qauv suav nrog qhib cell (iav thiab PCB) thiab teeb pom kev zoo.
Vim tias cov kua siv lead ua kua tsis yog cov khoom siv rau tus kheej, nws yog qhov yuav tsum tau muab lub teeb pom kev cais.
Yog tias lub teeb ci tau muab tso rau tom qab qhib lub xovtooj, nws hu ua lub teeb pom kev zoo.
Nws tau hu ua tus qauv vim tias lub teeb pom kev zoo tau tsim los ntawm ntau qhov.
Feem ntau, nws feem ntau suav nrog lub teeb ci (xws li CCFL, LED), LGP (hloov kab lossis taw tes lub teeb ci rau hauv qhov chaw teeb ci), zaj duab xis kho qhov muag (feem ntau suav nrog qis diffuser, zaj duab xis prism, diffuser sab saud), thav duab yas, rov qab phaj ( los ntawm Kev Txhawb thiab kho).
