Cov qauv thiab lub hauv paus ntsiab lus ua haujlwm ntawm backlight

TheWhite LED Backlight rau Cov Khoom Siv yog lub teeb ci uas muab lub LCD vaj huam sib luag. Nws yog tsim los ntawm lub teeb ci, lub teeb qhia phaj, optical film, yas ncej, thiab lwm yam TheWhite LED Backlight rau cov khoom siv yuav tsum muaj cov yam ntxwv ntawm qhov ci ci, lub neej ntev, thiab teeb pom kev zoo. Tam sim no, muaj peb yam tseem ceeb ntawm Dawb LED Backlight rau Cov Khoom Siv: EL, CCFL thiab LED. Lawv muab faib ua ntug-lit thiab ncaj-lit hom raws li qhov chaw faib khoom ntawm lub teeb ci. Raws li LCD modules txuas ntxiv txhim kho mus rau qhov ci dua, sib dua, thiab cov khoom siv thinner, ntug-lit LEDWhite LED Backlight rau Cov Khoom Siv Hluav Taws Xob rau cov xov tooj ntawm tes tau dhau los ua qhov tseem ceeb ntawm lub xov tooj ntawm tesWhite LED Backlight rau cov khoom tsim kho.
Txij li cov qauv ncaj qha yog tuab dua thiab tsis ua raws li qhov sib txawv ntawm kev ua lub teeb, nyias thiab luv, lawv tam sim no feem ntau sab teeb. Lub luag haujlwm ntawm lub teeb qhia phaj yog coj cov kev taw qhia tawg ntawm lub teeb kom txhim kho qhov ci ntawm lub vaj huam sib luag thiab xyuas kom meej qhov sib xws ntawm vaj huam sib luag ci ci. , qhov zoo ntawm lub teeb qhia phaj muaj qhov cuam tshuam zoo rau ntawm White LED Backlight rau Cov Khoom Siv Phaj, uas yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm ntug-litWhite LED Backlight rau cov khoom siv phaj. Lub teeb qhia phaj siv txoj kev txhaj tshuaj molding los nias acrylic rau hauv lub phaj nrog lub ntsej muag du, thiab tom qab ntawd siv cov khoom siv zoo heev thiab tsis yog lub teeb-absorbing los luam cov diffusion dots rau hauv qab ntawm lub teeb qhia phaj los ntawm kev tshuaj ntsuam luam ntawv. Lub teeb qhov chaw nyob rau sab ntawm lub teeb qhia phaj.
Nyob rau sab, lub teeb emitted yog kis mus rau lwm qhov kawg los ntawm kev xav. Thaum lub teeb hits lub diffusion point, lub teeb pom kev zoo yuav kis mus rau txhua lub ces kaum, thiab tom qab ntawd tawm los ntawm lub teeb qhia pem hauv ntej, siv ntau qhov ceev thiab ntau qhov sib txawv ntawm cov ntsiab lus diffusion. Nws tuaj yeem ua rau lub teeb qhia phaj ci sib npaug. Lub hom phiaj ntawm lub phaj reflective yog kom muaj kev cuam tshuam lub teeb pom kev nyob rau hauv qab rov qab rau hauv lub teeb qhia phaj los txhim kho kev ua tau zoo ntawm kev siv lub teeb. Cov ntawv qhia lub teeb tuaj yeem muab faib ua cov ntawv luam tawm thiab tsis luam tawm raws li cov txheej txheem sib txawv.
Cov ntawv luam tawm siv cov khoom siv uas muaj kev cuam tshuam siab thiab tsis pom lub teeb ntawm lub phaj acrylic, thiab ib puag ncig lossis square duab yog luam tawm rau hauv qab ntawm lub teeb qhia phaj los ntawm kev tshuaj ntsuam luam ntawv. diffusion point. Hom ntawv tsis yog siv cov pwm precision txhaj tshuaj me me ntawm cov ntaub ntawv granular nrog qhov sib txawv refractive index rau hauv cov khoom siv acrylic thaum txhaj tshuaj molding ntawm lub teeb qhia phaj kom ncaj qha rau cov pob me me, uas ua haujlwm zoo li dots. Tam sim no, feem ntau cov tuam txhab lag luam hauv tsev tseem siv cov ntawv luam tawm cov ntawv qhia ua lub teeb qhia cov khoom.
Cov ntawv luam tawm cov ntawv qhia lub teeb muaj qhov zoo ntawm tus nqi qis thiab kev tsim khoom sai, thaum cov ntawv qhia tsis yog cov ntawv luam tawm yog qhov nyuaj dua, tab sis muaj kev ua tau zoo hauv qhov ci. Pwm txoj kev loj hlob Technology yog lub bottleneck. Tsis tas li ntawd, raws li cov duab, nws tuaj yeem muab faib ua cov vaj huam sib luag tiaj tus thiab cov npoo-puab boards. Cov vaj huam sib luag tiaj tus feem ntau yog siv rau hauv cov saib, thiab cov npoo zoo li cov laug cam feem ntau yog siv hauv phau ntawv computers. Raws li rau lub hom phiaj tseem ceeb ntawm diffusion phaj, nws yog los txhim kho qhov ci ntsa iab ntawm lub hauv ntej ntawm cov khoom. Nws tuaj yeem ua rau lub teeb pom kev zoo sib xws kom cov duab ntxoov ntxoo ntawm qhov cuam tshuam tsis tuaj yeem pom ntawm sab xub ntiag. Tsis tas li ntawd, txij li qhov ncaj qha ntawm lub teeb tom qab nws tawm ntawm lub phaj diffuser yog qhov tsis zoo, daim ntawv prism (optical film) yuav tsum tau siv los kho cov kev taw qhia ntawm lub teeb kom ua tiav cov txiaj ntsig ntawm condensing lub teeb thiab txhim kho qhov ci ntawm lub teeb. pem hauv ntej.
