Dab tsi yog backlight

Dab tsi yog backlight?

Lub backlight module yog lub teeb pom kev uas muaj teeb pom kev nyob tom qab ntawm cov kua siv lead ua kua, lcd).

Nws lub ntsiab muaj nuj nqi yog los muab cov backlight rau ntawm lcd . saib cov duab ci, hauv backstal module { kom pom cov duab ntshiab .

Cheebtsam Backlight

Lub hauv paus tseem ceeb uas ua rau lub backlight module nyob rau hauv tiaj-vaj huam sib luag qhia yog:

Qhov Chaw Teeb:

Lub hauv paus yog feem ntau coj (lub teeb-emitting diode) thev naus laus zis.
LED cov txiaj ntsig zoo xws li loj me me, lub neej tsis tshua muaj zog, kav ntev, thiab muaj peev xwm pab tau lub zos dimming .
Lub Teeb Qhia Cov Phaj (LGP):

Lub teeb taw qhia phaj yog cov tseem ceeb tivthaiv ntawm Backlight module .
Nws yog ua los ntawm cov khoom siv hluav taws xob pob tshab cov khoom siv nrog cov khoom kho tshiab zoo nkauj .
Tus LGP yog lub luag haujlwm rau kev coj ua thiab faib cov LED-tsim lub teeb thoob plaws tag nrho cov cheeb tsam ntawm tag nrho cov cheeb tsam {}}
Reactor Sheated:

Daim ntawv qhia txog daim ntawv qhia yog nyob rau sab nraum qab ntawm lub teeb qhia phaj .
Nws yog ua los ntawm cov kev cuam tshuam loj me me li ultrasonic.
Tus reflea reflector cov ntawv pab kom muaj kev cuam tshuam lub teeb thiab txhim kho lub teeb ci zuag qhia tag nrho backlight .
Diffuser Sheet:

Lub diffuser daim ntawv yog muab tso rau pem hauv ntej ntawm lub teeb qhia phaj .
Nws ntxiv scatters thiab homogenizes lub teeb, ua kom pom kev zoo thoob plaws ntawm cov zaub saum npoo .
Qhov no pab tiv thaiv cov kub lossis tsis sib haum xeeb .
Ncej:

Cov Txheej Txheem Txheej Txheem yog lub luag haujlwm rau kev nyab xeeb tuav thiab tiv thaiv cov ntsiab lus ntawm lub backlight module .
Nws tswj hwm cov qauv txheej txheem ntawm tag nrho Backlight sib dhos .
Cov ntsiab lus tseem ceeb ua haujlwm ua ke los hloov chaw teeb pom kev zoo thiab kev sib xyaw ua ke ntawm cov teeb meem tsim nyog thiab kev sib koom ua ke ntawm cov kev ua haujlwm zoo

Lub luag haujlwm ntawm Backlight

1. teeb pom kev zoo:
- Backlight module muab cov khoom siv kom tsim nyog rau cov zaub vaj huam sib luag .
- nws converts lub teeb los ntawm LED (Lub Teeb-emitting Diode) teeb rau hauv cov khaub ncaws hnav, cov planar illation .
- Qhov kev sib txuas no yog qhov tseem ceeb rau cov zaub vaj huam sib luag ua haujlwm kom zoo thiab tsim cov duab pom kom pom tseeb zoo thiab tsim cov duab pom.

{{02. ci ci thiab sib piv:
- Backlight Module txiav txim siab qhov ci ci tag nrho thiab sib piv ntawm cov ntsiab lus tso tawm.
- los ntawm kev tswj hwm kev siv thiab faib ntawm lub backlight, nws tuaj yeem txhim kho qhov ci ci ci thiab sib piv ntawm cov duab .
- Qhov no yog tshwj xeeb yog qhov tshwj xeeb tshaj yog rau kev ua tiav cov khoom zoo, visually thov tawm cov zaub ua haujlwm .

3. Zog Kev Txhim Kho:
- Backlight module, nrog nws cov teeb pom kev zoo, feem ntau ntau dua hluav taws xob ntxiv rau cov thev naus laus zis ua ke, ccfls).
- Kev siv cov coj thiab ua kom muaj zog faib rau lub nraub qaum tuaj yeem txo qis kev noj hluav taws xob tag nrho

Hauv cov ntsiab lus, lub backlight module yog qhov tseem ceeb hauv cov duab tiaj tus zoo li kev ua kom zoo nkauj thiab cov neeg siv khoom siv tshiab {}}
