Judging los ntawm yav dhau los piv txwv kom deb li deb, tag nrho-xim LED cov ntxaij vab tshaus yog lub mainstream zaub ntaus ntawv Cheebtsam nyob rau hauv lub lag luam tam sim no. Ntau lub tuam txhab LED zaub tau ib txwm tsis muaj lub tswv yim ntawm kev tsim qhov loj ntawm cov xim puv xim LED hauv kev tsim thaum ntxov. Nquag, qhov loj ntawm lub vijtsam puv xim LED yog tsim los ntawm peb yam. Thawj yog nws qhov chaw teeb tsa, qhov thib ob yog qhov loj me ntawm lub vijtsam LED qhov dav thiab qhov siab, thiab qhov thib peb yog cov ntsiab lus uas feem ntau ua si, uas yog, kev tshaj tawm. Kev tshaj tawm, kev tshaj tawm, yeeb yaj kiab kab tshoob, kev kaw suab hauv TV thiab tshaj tawm, cov ntsiab lus xim xim luam ntawv, thiab lwm yam ... Muaj coob tus neeg tsis paub tias tus qauv tsim yog dab tsi, cia peb txheeb xyuas hauv qab no.
Tsim cov xim puv xim LED
1. Qhov loj tshaj plaws ntawm LED zaub: LED puv xim cov ntxaij vab tshaus tuaj yeem ua cov yeeb yaj kiab sib txawv raws li ib puag ncig, xws li tus kheej tsim LED tshaj tawm cov yeeb yaj kiab, nws tus kheej kaw cov ntaub ntawv video, TV relays, yeeb yaj kiab lom ze, kev tshaj tawm kev lag luam, thiab yog li ntawd. Qhov kev faib ua feem ntawm cov ntsiab lus video tsim los ntawm lub tuam txhab tshaj tawm feem ntau tuaj yeem tsim raws li LED puv xim npo piv. Cov kev pab cuam video kaw los ntawm cov qhua xws li mus ncig thiab ua si, kab tshoob hnub tseem ceeb, tuam txhab kev tshaj tawm, kev tshwm sim selfies, thiab lwm yam. Cov duab piv yuav tsum yog raws li qhov piv ntawm cov cuab yeej tua kom txhais tau, xws li xov tooj ntawm tes, koob yees duab, koob yees duab digital, camcorders, thiab lwm yam....

Yog li ntawd, ua ntej peb ua LED puv-xim zaub, peb yuav tsum muaj kev tshawb fawb tob thiab npaj cov ntsiab lus ntawm kev tshaj tawm. Yog tias qhov tsis sib xws ntawm qhov sib piv ntawm cov xim LED puv npo thiab qhov sib piv ntawm qhov kev tshaj tawm hauv xov tooj cua yuav ua rau cov duab compressed thiab qhov muag plooj, thiab cov nyhuv tshwm sim yuav txawv heev. Qhov seemingly proportional distortion teeb meem yuav ua raws li ib tug tom qab lwm, tab sis yog hais tias peb ntsib tej teeb meem no, peb muaj peev xwm nws yog teem los ntawm cov tsis muaj LED zaub. Sab saum toj, hauv qab, sab laug, thiab sab xis ntawm tag nrho cov xim LED zaub yog sab laug los yog sau nrog cov ntaub ntawv scrolling. Xws li tus qauv tsim tau zoo tshaj plaws nyob rau hauv raws li qhov sib piv ntawm qhov screen LED.
2. Kev teeb tsa ib puag ncig ntawm LED zaub: Peb txhua tus paub tias tag nrho cov xim LED zaub tau muab faib ua sab hauv LED zaub thiab sab nraum zoov LED zaub. Sab hauv LED zaub feem ntau yog qhov chaw ib-zaj dab neeg, thiab nws qhov dav feem ntau tsis cuam tshuam. Qhov siab yog ib txwm nyob nruab nrab ntawm 2-5 meters. Sab nraum zoov LED puv xim loj npo feem ntau tsis txwv los ntawm qhov loj. Qhov dav thiab qhov siab tuaj yeem hloov kho tau yooj yim. Nws tuaj yeem hloov kho raws li tus neeg siv nyiam. Qhov tsuas yog qhov tsis txaus yog qhov teeb tsa ntawm qhov chaw tshaj tawm los ntawm cov tswv.
Ib yam li lub tsev muaj ntau lub plag tsev, thawj pem teb yog lub qhov rooj nkag thiab cov neeg taug kev txoj kev tsis muaj, qhov qis dua ib nrab ntawm cov phab ntsa sab nrauv ntawm lub tsev thib peb feem ntau yog cov ntawv kos npe ntawm cov khw hauv thawj pem teb, thiab 4th, 5th, thiab 6th pem teb feem ntau yog cov ntawv loj loj.

Yog li ntawd, nws yuav muab faib ua ob peb thaj chaw. Yog tias koj xav ua kom muaj LED puv xim npo tshaj tawm txoj haujlwm ntawm txoj haujlwm no, qhov loj me yog qhov kev zam. Yuav muaj kev txwv. Rau kev sib koom ua ke tag nrho, peb yuav tsum lees txais tag nrho cov phiaj xwm txheej txheem, thiab tsuas yog tsim tau raws li qhov loj me uas muab los ntawm tus neeg xauj tsev. Yog tias tsis muaj kev npaj rau 4th, 5th, thiab 6th pem teb, ces tag nrho-xim LED Qhov loj ntawm lub vijtsam tuaj yeem tsim los ntawm arbitrarily. Tsim raws li cov zaub koj nyiam
