LED zaub tau txais kev saib xyuas thoob plaws txij li thaum nws yug los. Nrog kev nce qib txuas ntxiv ntawm kev teeb tsa thev naus laus zis hauv xyoo tas los no, nws tau lees paub thiab siv rau hauv ntau qhov kev lag luam. Kev tsim khoom thiab kev saib xyuas ntawm cov lus qhia coj los kuj xav tau kev paub txog kev txawj ntse. Yuav ua li cas kom tau txais high-txhais zaub? Yuav kom ua tiav cov ntsiab lus siab, yuav tsum muaj plaub yam: ib qho yog tias qhov chaw ua yeeb yaj kiab yuav tsum muaj tag nrho cov ntsiab lus siab; Qhov thib ob yog tias cov zaub yuav tsum txhawb nqa tag nrho cov ntsiab lus siab; qhov thib peb yog los txo cov dot pitch ntawm cov zaub coj; Qhov thib plaub yog kev sib xyaw ua ke ntawm cov duab coj thiab cov video processor. Tam sim no, tag nrho-xim LED zaub tseem tab tom txav mus rau lub ntsiab lus siab dua.
Full xim coj zaub
1. Txhim kho qhov sib piv ntawm LED puv xim zaub. Qhov sib txawv yog ib qho tseem ceeb uas cuam tshuam rau qhov pom kev. Feem ntau hais lus, qhov siab dua qhov sib piv, qhov pom tseeb thiab pom cov duab ntau dua, thiab cov xim ci dua thiab ci dua. High contrast yog pab tau heev rau cov duab clarity, nthuav dav kev ua tau zoo, thiab grey theem kev ua tau zoo. Hauv qee cov ntawv nyeem thiab cov yeeb yaj kiab uas muaj qhov sib txawv loj ntawm cov xim dub thiab dawb, cov xim zoo nkauj ntawm cov xim LED muaj qhov zoo sib xws hauv cov xim dub thiab dawb, qhov pom tseeb, thiab kev ncaj ncees. Qhov sib piv muaj qhov cuam tshuam ntau dua rau cov nyhuv dynamic video. Vim tias qhov hloov pauv ntawm lub teeb-tsaus nyob rau hauv cov duab dynamic yog sai dua, qhov siab dua qhov sib piv, qhov yooj yim dua rau tib neeg lub qhov muag kom paub qhov txawv ntawm cov txheej txheem hloov dua siab tshiab. Qhov tseeb, qhov sib txawv ntawm kev txhim kho ntawm LED puv xim npo yog tsuas yog ua kom lub ci ci ntawm cov xim puv xim LED thiab txo qhov kev xav ntawm qhov screen. Txawm li cas los xij, qhov ci ntsa iab tsis yog siab npaum li qhov ua tau, siab dhau lawm, tab sis nws yuav ua rau muaj kev cuam tshuam, tsis tsuas yog cuam tshuam rau LED zaub Lub neej ncua yuav ua rau lub teeb paug. Lub teeb muaj kuab paug tau dhau los ua lub ntsiab lus kub tam sim no, qhov ci ntsa iab dhau lawm yuav cuam tshuam rau ib puag ncig thiab tib neeg. Tag nrho-xim LED zaub LED vaj huam sib luag thiab LED lub teeb-emitting raj yog kho nrog cov txheej txheem tshwj xeeb, uas tuaj yeem txo qhov kev xav ntawm LED vaj huam sib luag thiab ua rau kom qhov sib txawv ntawm cov xim puv LED.
2. Nce qib grey ntawm LED puv xim zaub. Grey theem yog hais txog tus naj npawb ntawm qhov ci ci uas tuaj yeem sib txawv ntawm qhov tsaus ntuj tshaj plaws mus rau qhov ci tshaj plaws hauv qhov ci ntawm ib qho xim thawj ntawm LED puv xim npo. Cov qib grey ntawm Winbond cov xim puv xim LED Qhov ntau dua tus nqi, cov xim nplua nuj thiab cov xim ci dua; ntawm qhov tsis sib xws, cov xim zaub yog ib leeg thiab qhov kev hloov pauv yooj yim. Qhov nce ntawm qib grey tuaj yeem ua rau kom cov xim qhov tob, ua rau cov duab theem ntawm cov duab xim nce geometrically. Lub LED grey tswj theem yog 14-16-ntsis, ua rau cov duab theem daws teeb meem cov ntsiab lus thiab tso saib cov teebmeem ntawm high-end zaub cov khoom ncav cuag lub ntiaj teb qib siab. Nrog rau kev txhim kho cov cuab yeej siv thev naus laus zis, LED grey nplai yuav txuas ntxiv txhim kho kom muaj kev tswj xyuas ntau dua.
3. Txo qhov dot pitch ntawm LED puv xim zaub. Txo qhov dot pitch ntawm LED puv xim zaub los txhim kho nws qhov pom tseeb. Qhov me me ntawm qhov dot pitch ntawm tag nrho cov xim LED zaub, qhov muag pom ntau dua qhov screen. Txawm li cas los xij, qhov no yuav tsum muaj cov cuab yeej paub tab raws li kev txhawb nqa tseem ceeb. Tus nqi nkag yog qhov loj, thiab tus nqi ntawm cov xim puv xim LED tsim los kuj yog siab. Hmoov zoo, kev ua lag luam tam sim no tsiv mus rau me me-pitch LED zaub.
4. Kev sib xyaw ua ke ntawm LED puv xim zaub thiab video processor. LED video processor siv tau cov algorithms siab heev los hloov cov teeb liab nrog cov duab tsis zoo, ua cov txheej txheem xws li de-interlacing, ntug sharpening, kev them nyiaj yug, thiab lwm yam, los txhim kho cov duab cov ntsiab lus, txhim kho cov duab zoo. Lub video processor duab scaling algorithm yog siv los xyuas kom meej tias cov duab yees duab yog scaled kom muaj lub sharpness thiab grey theem ntawm cov duab mus rau qhov loj tshaj plaws. Tsis tas li ntawd, tus txheej txheem video tseem yuav tsum muaj ntau yam kev hloov kho cov duab thiab cov teebmeem kev hloov kho, thiab ua cov duab ci ntsa iab, qhov sib piv, thiab greyscale kom ntseeg tau tias qhov screen tso tawm cov duab mos thiab meej.
