LCD TV backlight module qauv

1. Taw qhia rau Backlight Module

Backlight module yog ib qho ntawm cov khoom tseem ceeb ntawm LCD vaj huam sib luag. Txij li cov kua siv lead ua kua nws tus kheej tsis tawm lub teeb, kev ua haujlwm ntawm lub teeb pom kev zoo yog muab cov ci ntsa iab txaus thiab cov teeb pom kev zoo sib xws los ua kom nws cov duab zoo li qub. LCD panels tam sim no tau siv dav hauv cov khoom siv hluav taws xob uas muaj peev xwm loj hlob xws li saib, khoos phis tawj khoos phis tawj, koob yees duab digital, thiab projectors. Yog li ntawd, qhov kev thov rau backlight modules thiab cov khoom muaj feem cuam tshuam txuas ntxiv, txhawb nqa los ntawm cov nqi vaj huam sib luag qis. , Thiab qhov kev thov loj tshaj plaws rau cov vaj huam sib luag loj xws li phau ntawv teev cov khoos phis tawj thiab LCD saib yog lub hauv paus tseem ceeb ntawm kev tsav tsheb rau kev loj hlob ntawm kev thov rau backlight modules. Nws tseem yog qhov tseem ceeb thib ob ntawm LCD panels.

2. Backlight module qeb:

Feem ntau hais lus, backlight module tuaj yeem muab faib ua ob hom: lub teeb pem hauv ntej thiab rov qab teeb. Lub backlight module tuaj yeem raug cais raws li qhov yuav tsum tau ua ntawm nws qhov ntsuas thiab txoj haujlwm ntawm lub teeb, thiab peb hom hauv qab no tau tsim. qauv:

(1) Ntug teeb pom kev zoo qauv: Lub teeb ci yog ib qho teeb pom kev zoo tso rau ntawm sab, thiab lub teeb qhia phaj yog tsim los rau kev txhaj tshuaj molding yam tsis muaj luam ntawv. Nws yog feem ntau siv rau me me thiab nruab nrab-qhov loj me backlight modules hauv qab 18 ntiv tes. Qhov teeb meem teeb pom kev zoo tsim muaj cov yam ntxwv ntawm lub teeb yuag, thinness, nqaim thav duab thiab siv hluav taws xob tsawg. Nws tseem yog lub teeb ci rau lub xov tooj ntawm tes, tus kheej cov pab cuam (PDA), thiab cov khoos phis tawj. Tam sim no, kuj tseem muaj qhov loj-loj backlight modules uas txais yuav hom teeb pom kev. qauv.

(2) Cov qauv teeb pom kev zoo hauv qab: lub teeb pom kev zoo ultra-loj, lub teeb pom kev sab nraud tsis muaj qhov zoo ntawm qhov hnyav, kev siv hluav taws xob thiab ci ntsa iab, yog li nws tsis muaj lub teeb qhia phaj thiab lub teeb ci tau muab tso rau hauv qab ntawm hom ncaj qha. Tus qauv tsim. Lub teeb qhov chaw muaj lub teeb pom kev zoo (xws li teeb, lub teeb-emitting diodes)

Etc.) Tom qab tau txais kev cuam tshuam los ntawm lub reflector, nws yog emissions nyob rau hauv pem hauv ntej nto tom qab nws tusyees dispersed upwards los ntawm lub diffuser. Raws li qhov chaw teeb tsa loj dua, lub teeb tuaj yeem siv tau txog li 2 lub teeb nyob ntawm qhov loj ntawm TFT vaj huam sib luag, tab sis tib lub sijhawm, lub thickness ntawm lub module yog nce. , Qhov hnyav, kev siv hluav taws xob, thiab nws qhov zoo yog qhov ci ntsa iab zoo, lub teeb pom kev zoo, kev siv lub teeb pom kev zoo, cov qauv yooj yim, thiab lwm yam, yog li nws yog qhov tsim nyog rau LCD saib thiab LCD TVs uas tsis tshua muaj kev xav tau ntawm kev txav mus los thiab qhov chaw yuav tsum tau ua. Cov teeb meem xws li kev siv hluav taws xob siab (siv cov raj cathode txias), tsis zoo ib yam thiab ua rau LCD cua sov tseem yuav tsum tau txhim kho.

(3) Hollow qauv: Raws li qhov loj ntawm cov duab yuav tsum tau nce, LCDs kuj tseem txhim kho nyob rau hauv cov kev taw qhia ntawm qhov loj me. Tam sim no xws li ultra-loj LCDs yog siv raws li cov saib thiab cov phab ntsa-mounted TVs, uas tsis tsuas yog yuav tsum tau cov ntxaij vab tshaus loj, siab brightness thiab lub teeb yuag, cov khoom siv hluav taws xob kuj yuav tsum tau thermal nyhuv nyob rau hauv siab zog. Nyob rau hauv xyoo tas los no, lub hollow qauv backlight module tsim siv kub cathode raj raws li lub teeb qhov chaw. Cov qauv no siv huab cua ua lub teeb kis nruab nrab. Tom qab lub teeb qhov chaw raug kho thiab rov qab los ntawm kev taw qhia ntawm daim ntawv prism thiab lub phaj reflecting, ib feem hla ntawm lub teeb qhia phaj nce mus thiab tawm ntawm qhov chaw, thiab lwm qhov nkag mus rau hauv qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. nyob rau hauv kev xav. Tom qab ua yeeb yam, nws tawm los ntawm lub teeb qhia phaj, thiab lub teeb sab saud yog ncaj qha nkag mus rau lub teeb qhia phaj thiab tawm, los yog tawm tom qab ib qho kev xav ntawm kev xav: cov duab ntawm lub teeb qhia phaj yog cov qauv zoo li lub npoo, thiab lub hom phiaj yog kom ua tiav cov txiaj ntsig zoo ib yam.

Taw qhia rau qhov tseem ceeb optical Cheebtsam ntawm lub backlight module:

Lub backlight module feem ntau muab cov teeb pom kev zoo thiab lub teeb ci siab rau cov kua siv lead ua kua vaj huam sib luag. Lub hauv paus ntsiab lus tseem ceeb yog hloov lub ntsiab lus los yog kab teeb pom kev zoo rau hauv lub teeb ci siab thiab teeb pom kev zoo ntawm cov khoom siv los ntawm lub teeb pom kev yooj yim thiab siv tau zoo. Cov qauv dav dav yog siv cov kab teeb pom kev zoo ntawm lub raj cathode txias kom nkag mus rau lub teeb qhia phaj los ntawm lub teeb pom kev, hloov lub teeb pom kev zoo rau hauv qhov chaw teeb pom kev zoo, thiab tom qab ntawd siv lub teeb homogenization ntawm daim ntawv diffuser thiab Lub teeb sib sau ua haujlwm ntawm daim ntawv prism los txhim kho qhov ci ntsa iab thiab qhov sib xws ntawm lub teeb ci. Kev sib tw. Ntawm no peb yuav qhia txog qee qhov tseem ceeb ntawm lub teeb ci module.

3. Backlight module muaj pes tsawg leeg: Lub teeb qhov chaw, lub teeb qhia phaj, vaj tse, reflector, diffuser, brightness li zaj duab xis (BEF, prism zaj duab xis), dub thiab dawb kua nplaum (Curtain daim kab xev) thiab hais txog. Raws li cov kev xav tau ntawm lub teeb pom kev zoo tau txais kev sib tw thiab nyias, qee qhov yuav tsum tau ntxiv nrog cov ncej hlau (METAL FRAME).

Lub teeb rov qab

Backlight yog ib hom teeb pom kev zoo, feem ntau siv rau cov duab LCD. Qhov sib txawv ntawm hom backlight thiab lub teeb pem hauv ntej yog qhov backlight yog illuminated los ntawm sab los yog sab nraum qab, thaum lub teeb pem hauv ntej yog illuminated los ntawm pem hauv ntej raws li lub npe implies. Lawv tau siv los ua kom lub teeb pom kev zoo nyob rau hauv qhov chaw qis qis thiab qhov ci ntawm lub computer saib thiab cov ntxaij vab tshaus siv lead ua kua los ua kom pom lub teeb zoo ib yam li CRT cov lus qhia. Lub backlight tuaj yeem yog xim xim. Monochrome kua crystals feem ntau muaj backlights xws li daj, ntsuab, xiav, thiab dawb. Cov xim zaub siv lub teeb dawb vim tias nws npog ntau qhov ntxoov ntxoo.

Module

QTW module hais txog lub npe dav dav ntawm cov khoom siv uas tuaj yeem paub txog cov lus tsa suab hauv kev lag luam automation, tseem hu ua positioning module. Linear modules tuaj yeem suav hais tias yog cov kws tsim kho tshuab los ntawm kev hloov pauv ntawm cov tshuab thiab kev tsim cov tshuab, sib qhia kev paub thiab sib pauv kev paub, thiab thaum kawg tuaj rau cov khoom siv kev paub ntau.

qhov kaj

Lub teeb ci yog hais txog qhov ci ntsa iab ntawm qhov khoom nws tus kheej. Qee yam khoom nyob hauv lub qab ntuj khwb yog luminous thiab ib txhia tsis-luminous. Peb hu cov khoom uas muaj peev xwm emit lub teeb ntawm lawv tus kheej thiab yog luminous li lub teeb qhov chaw. Lub hnub, hluav taws xob teeb, taws tswm ciab, thiab lwm yam yog txhua yam teeb pom kev zoo.
