Dab tsi yog qhov txawv ntawm LED thiab Direct Luminescence

LED backlight qhov chaw ntawm sab luminous thaj yog lub backlight ua los ntawm kab-shaped los yog dot-shaped teeb qhov chaw nyob rau sab ntawm sab ntawm lub teeb tshwj xeeb qhia phaj. Txoj kev ncaj nraim backlit backlight yog qhov yooj yim. Nws tsis xav tau lub teeb qhia board. Nws yog tso lub teeb ci (LED nti array) thiab PCB nyob rau hauv qab ntawm lub teeb backlight. Tom qab lub teeb raug tua los ntawm LED Lub membrane tua uniformly. Cov Lus Teb Ntxiv: Thaum LED backlighting qhov chaw siv rau lub LCD loj loj, qhov hnyav thiab tus nqi ntawm lub teeb qhia lub rooj tsavxwm yuav nce nrog qhov loj, thiab lub teeb ci thiab qhov sib xws yuav tsis zoo tagnrho. Nyob rau tib lub sijhawm Vim tias LCD TVs tsis tuaj yeem ua tiav cov kev tswj hwm hauv cheeb tsam ntawm LCD TVs, lawv tsuas tuaj yeem ua tiav qhov yooj yim ib-dimensional teeb hloov, thaum lub teeb ncaj-down LED backlight kev ua tau zoo dua. Nws tuaj yeem ua tiav hauv cheeb tsam dynamic tswj ntawm LCD TV. Sab nraub qaum lub teeb tuaj yeem nyias nyias, tab sis qhov kev siv lub teeb ntawm lub teeb pom kev zoo yog qhov me me, thiab qhov thinner tus nqi siv, qhov siv tsawg dua. Lub hauv paus ntawm nws cov thev naus laus zis yog kev tsim thiab tsim cov ntawv qhia lub teeb. Tam sim no, muaj ob hom kev luam ntawv thiab tua ua cov duab. Nyob rau hauv daim ntawv ntawm lub teeb qhia board, lwm yam xws li shooting molding ntxiv luam ntawv, laser dots, corrosion, thiab lwm yam., tsis haum rau batch ntau lawm cov qauv. Qhov zoo ntawm kev ncaj nraim backlight technology yog high-profile, zoo qhov hluav taws xob saib lub kaum sab xis, siab siv lub teeb efficiency, yooj yim qauv, thiab lwm yam. Khaws ib qho chaw nruab nrab ntawm lub diffuser thiab LED teeb qhov chaw los txhim kho qhov sib xws ntawm qhov ci. Yog li ntawd, lub teeb rov qab ncaj kuj nce lub thickness, qhov hnyav, thiab lub zog noj ntawm lub module. Yog li ntawd lub teeb backlight.
