LED backlight thov rau txoj kev loj hlob ntawm phau ntawv cov computers

Hais txog cov yam ntxwv ntawm LED Cheebtsam, nws muaj tus lej ntawm cov tswv yim kev siv tswv yim tsim cov khoom lag luam, tab sis qhov tseeb feem thiab kev tsim nqi tau dhau los ua txoj hauv kev zoo rau kev muag khoom ntawm cov khoom kawg. Piv txwv li, feem ntau cov chaw tsim khoom tsim cov lag luam high-end thin thiab lub teeb notebook computers tib lub sijhawm. , Tsis tas li ntawd ua kom paub sab-zes lossis txhim kho LED sab nraum zoov teeb vaj huam sib luag tsim nrog cov txiaj ntsig tsim tsim qis, tab sis cov khoom ntim ntim cov nyhuv tsis muaj teeb ci thiab nyias li lub tiaj Dot qauv tsim. Vim tias tam sim no cov duab hluav taws xob qhia kev teeb tsa phaj phaj qauv tsim kom muaj cov tuab tsawg kawg 0.5 ~ 2.5mm, yog tias tus qauv ntawm CCFL teeb pom kev zoo los ua ke siv, LED Circuit Court thiab lub teeb qhia phaj qauv qauv tsuas yog hloov kho me ntsis, thiab cov vaj huam sib luag thickness yuav txog 2 ~ 2.5mm.

Cov qauv ntawm LED Cheebtsam yuav tseem cuam tshuam kev ua tiav ntawm qhov khoom kawg

Tsis tas li ntawd, tseem muaj cov sib txawv hauv cov LED-lub teeb hluav taws xob tiv thaiv nws tus kheej uas coj tus nqi thiab cov txiaj ntsig zoo. Piv txwv li, cov phau ntawv siv xov tooj qhia siab tsim tsim nyias thiab tsim kom pom lub teeb, thiab feem ntau siv hluav taws xob ntsia sab saum toj pom sab hauv LED. Tam sim no, LED cheebtsam nrog qhov siab ntawm 3 ~ 3.5 hli feem ntau yog npaj nyob rau hauv Nyij Pooj. Txawm hais tias lub Cheebtsam yog nruab Cov khoom tsim nyias nyias qhov zoo, tab sis tus nqi kuj tseem yuav nyob siab. Tus txheeb ze rau cov khoom lag luam nkag, feem ntau ntawm theem pib tsoos qauv LED tsim qauv txuas ntxiv. Tam sim no, qhov siab ntawm cov khoom sib txuam tuaj yeem tsawg li 4 ~ 4.5mm. Tsis tas li ntawd, qhov tsis ua kom cov nplaum ua kom pom tseeb ua rau cov khoom sib txawv muaj qhov siab me ntsis sib txawv tom qab ntsaws-tshuab, thiab cov khoom yog nyias nyias Cov qauv tsim muaj qee qhov kev txwv, tab sis nws muaj cov zoo heev tiv nqi nqe kom zoo dua.

Feem ntau nruab nrab thiab loj laptop teeb tseem siv CCFL backlight tsim

Hauv phau ntawv sau kev lag luam ntawm nruab nrab thiab loj panels, vim tias tus nqi siab, feem ntau ntawm lawv tseem txais CCFL backlight tsim. Txawm hais tias cov khoom tiav tiav yuav hnyav dua me ntsis, tus nqi qis dua tus nqi txhim kho ntawm LED teeb tsa thiab cov lus qhia tshwj xeeb coj los ua phaj xav kom ua rau cov phiaj xwm loj. Nyob rau tam sim no, lub thickness ntawm phau tshuab computer tsim tsim rau nruab nrab thiab siab kawg CCFL backlight qhov chaw tuaj yeem ncav cuag 1 ~ 2 hli. Lub wedge-puab lub teeb qhia lub teeb hom teeb tsa ncaj qha teeb ntsuab LEDs. Ntxiv rau qhov ncav cuag lub teeb pom kev zoo ntawm kev lag luam LED Cheebtsam, nyob rau hauv cov xwm txheej ntawm thinning thiab tus nqi, Tsis tas yuav tsum maj nrawm ua kom paub cov qauv tsim LED, uas yog qhov laj thawj vim li cas feem ntau ntawm cov tam sim no nruab nrab- thiab qis-kawg phau computers tseem. tsis tau nquag siv LED teeb rov qab.

Qhov sib txawv ntawm kev soj ntsuam lub vaj huam sib luag tiaj tiaj thiab cov npoo ntawm daim duab tsim tshwj xeeb vim yog qhov sib txawv ntawm cov qauv saum npoo ntawm Dot thiab V-Txiav. Yog tias tib lub tuab yog siv rau kev sim thiab kev sib piv, lub teeb pom kev zoo ntawm lub teeb taw qhia cov phaj ntawm Cov Qauv Dot raug txwv los ntawm cov yam ntxwv ntawm lub teeb, thiab nws qhov kev ua tau zoo yog tsawg dua V-txiav qauv tsim. Nyob rau tam sim no, rau qhov sai thiab meej cov khoom ntawm cov lus qhia coj teeb, feem ntau ntawm lawv txais kev coj ua lub teeb qhia kev tsim cov yas nrawm txhaj tshuaj molding. Qhov sib txawv ntawm tus qauv tsim ntawm Dot thiab V-Ntuag ua rau Dot saum npoo av thiab qhov ua tau zoo yog qhov zoo. Nws yog vim hais tias tus qauv ntawm V-txiav yog qhov nyuaj me ntsis, qhov txiaj ntsig ntawm kev tsim tawm yog qhov tsis tshua pom, uas ua rau V-Cut lub teeb qhia qauv ntau txoj hauv kev sib xyaw thiab kev sib dhos, thiab ua rau kev lag luam cuam tshuam poob siab.

Lwm cov tsim qauv daws teeb meem

Saib tag nrho cov qauv siv ntawm LED backlight tsim nyob rau hauv phau ntawv sau phib tawj, nqi tseem yog qhov tseem ceeb rau kev txiav txim siab seb puas yuav ntshuam lossis tsis. Tshwj tsis yog tias nws yog qhov qauv nyias thiab lub teeb nrog chav siab tus nqi, kev qhia ntawm LED tsim tsis yog sib npaug ntawm qhov kev lees tias cov khoom nyias tsim, qee tus nqi qis tus qauv qauv tseem yuav ua rau lub davhlau ya nyob twg tsim kom pom tuab. Hais txog cov nqi thiab cov txiaj ntsig, ntau ntawm LED backlight cov khoom lag luam tau nthuav dav. Tam sim no, 13-nti me me thiab nruab nrab cov ntxaij vab tshaus feem ntau siv, vim hais tias tsis hais txog Dot lossis V-txiav teeb, qhov ntau ntawm cov khoom siv LED rau cov ntawv me me thiab nruab nrab yog qhov qub. Nws yog qhov txo qis heev, thiab thaj tsam ntawm daim phiaj coj kev teeb tsa kuj tseem tuaj yeem txo tau kom zoo, thiab tus nqi tseem nyob hauv qhov ntau yam kev lag luam tuaj yeem nqus tau.

Yog tias koj saib cov qauv loj ntawm 15-20 nti, tus nqi ntawm kev qhia ua lub teeb pom kev zoo ntawm LED yuav nce siab. Yog tias kev tsim thinner tsim nyob rau tib lub sijhawm, tus nqi ntawm cov khoom lag luam yuav nce siab ntxiv, thiab qhov teeb meem tawm los kuj yuav tsum tau coj mus txiav txim siab. Ntxiv rau cov Cheebtsam thiab cov phiajcim qhia lub teeb, tus yuam sij rau kev tsim cov teeb pom kev zoo ntawm LED rov qab yog tias cov yeeb yaj kiab kho qhov muag, qhov ua kom pom kev zoo dua tshiab tuaj, thiab diffusers siv hauv CCFL kuj tseem siv tau hauv LED tsim teeb ci. Piv txwv, cov yeeb yaj kiab kho qhov muag tshwj xeeb yog siv hauv LEDs thiab CCFLs. Cov kev ua tau ntawm cov sib txawv ntawm cov backlight tsis sib txawv. Tsis muaj kev txwv tsim ntawm kev siv cov diffusers lossis cov yeeb yaj kiab kho qhov muag. Txawm li cas los xij, feem ntau cov khoom lag luam qis qis feem ntau tsis xaiv cov hom kev daws teeb meem no, vim tias nws tuaj yeem nce lub teeb pom kev zoo los ntawm 15-20% lossis Nws yog txhawm rau txhim kho cov khaub ncaws tsis sib xws ntawm cov teeb ci ntawm cov ces kaum, tab sis nws kuj yog vim lub tus nqi siab, yog li tsis muaj ntau cov tuam ntxhab siv
