Installation thiab muaj pes tsawg leeg ntawm LED backlighting
May 17, 2022
I. Ntaus
LCD yog cov cuab yeej uas tsis muaj teeb pom kev zoo, yuav tsum tau cia siab rau lub teeb rov qab kom tuaj yeem tso saib cov ntaub ntawv lub luag haujlwm. Ntxiv nrog rau qhov zoo ntawm lub teeb pom kev zoo, tus nqi ntawm lub teeb pom kev zoo rau 3-5 feem pua ntawm LCD tswj module thiab 75 feem pua ntawm lub zog siv los ntawm kev tswj module. Cov ncauj lus kom ntxaws, loj loj LCDs yuav tsum tau ua kom tiav los ntawm superior coj backlight technology, yog li thaum lub LCD kev lag luam saw yog mob siab rau tsim tshiab loj daim ntaub ntawv, lub LED backlight technology yog ua superior nyob rau hauv kev ua tau zoo (xws li brightness, tsawg nqi, lub zog txuag, lub teeb yuag. , thiab lwm yam).
II. Kev sib xyaw
Qhov tseem ceeb muaj lub teeb ci, qhov chaw teeb pom kev zoo, lub mem tes damper rau electro-optics, thiab ib lub thav duab yas. Lub backlight qhov chaw yog ci dua, muaj lub neej ntev, thiab zoo ib yam ci. Nyob rau theem no, muaj peb hom backlight qhov chaw: EL, CCFL thiab LED, uas tau muab faib ua sab lub teeb hom thiab ncaj qha down hom raws li qhov sib txawv ntawm lub teeb qhov chaw. Raws li lub LCD vaj huam sib luag txuas ntxiv txhim kho nyob rau hauv cov kev taw qhia ntawm ci dua, sib dua thiab nyias, sidelight CCFL backlighting tau dhau los ua qhov nrov backlighting qauv ntawm theem no.
Electroluminescent (EL) backlighting yog nyias thiab lub teeb, thiab tsim ib qho teeb pom kev zoo. Nws muaj qhov ua haujlwm tsis zoo thiab qhov ntsuas qhov ua haujlwm tau teev tseg yog 80-100Vac. Lub zog hluav taws xob inverter nthuav qhia cov qauv ua haujlwm voltage tuaj yeem hloov 5/12/24Vdc tus yuam sij rau hauv kev sib txuas lus AC tso zis. Txawm li cas los xij, lub neej ntawm EL backlighting kuj tseem txwv (qhov nruab nrab ntawm lub neej ntawm 50 feem pua ntawm cov qauv chromaticity yog 3000 rau 5000 teev teev, nyob rau qib chromaticity siab dua lub neej yuav raug txo kom tsawg), yog li ntawd, qhov zoo tshaj plaws inverter fais fab mov rau EL backlighting dav teeb pom kev zoo. tso cai rau cov zis voltage thiab zaus kom nce ntxiv nrog rau qhov brittleness ntawm EL hluav taws xob qhov muag teev, yog li ua rau lub neej tsim nyog ntawm cov zaub ntawm xaiv EL backlighting luminaire teeb qhov chaw. Qhov no nyob rau hauv lem ua rau kom lub neej tsim nyog kev pab cuam ntawm cov lus qhia nrog EL-raws li inverter teeb pom kev zoo qhov chaw.
