Thaum ntug-lit LED backlights tau siv nyob rau hauv nruab nrab thiab loj-loj LCDs, qhov hnyav thiab tus nqi ntawm lub teeb qhia phaj yuav nce nrog qhov loj me, thiab qhov ci thiab qhov sib xws ntawm lub teeb emission tsis zoo tagnrho.Lub teeb vaj huam sib luag tsis tuaj yeem paub txog kev tswj hwm hauv cheeb tsam ntawm LCD TV, tab sis tsuas yog tuaj yeem paub qhov yooj yim ib-dimensional dimming, thaum lub teeb ncaj qha LED backlight ua tau zoo dua thiab tuaj yeem paub txog kev tswj hwm hauv cheeb tsam ntawm LCD TV.Cov txheej txheem ncaj qha rov qab yog qhov yooj yim thiab tsis xav tau lub teeb qhia phaj.Lub teeb ci (LED nti array) thiab PCB tau muab tso rau hauv qab ntawm lub teeb nraub qaum.Tom qab lub teeb tawm ntawm LED, nws dhau los ntawm lub teeb pom kev hauv qab, thiab tom qab ntawd dhau los ntawm diffuser rau saum npoo kom nce qhov ci.Zaj duab xis yog ejected tusyees.Lub thickness ntawm lub backlight yog tsuas yog txiav txim los ntawm qhov siab ntawm kab noj hniav ntawm lub reflective zaj duab xis thiab diffuser.Nyob rau hauv txoj kev xav, nyob rau hauv lub premise ntawm ua tau raws li lub installation yuav tsum tau thiab luminous brightness, qhov ntau dua cov kab noj hniav qhov siab, qhov zoo dua cov uniformity ntawm lub teeb emitted los ntawm lub diffuser.
