Yuav ua li cas kom LED zaub ntau dua-txhais

LED zaub tau txais kev saib xyuas thoob plaws txij li thaum nws yug los. Nrog kev nce qib ntawm kev txhim kho thev naus laus zis hauv xyoo tas los no, nws tau lees paub thiab siv rau hauv ntau yam lag luam. Kev tsim khoom thiab kev saib xyuas ntawm cov zaub coj los kuj xav tau kev paub txog kev txawj ntse. Yuav ua li cas kom ua tiav high-txhais zaub? Yuav kom ua tiav cov ntsiab lus siab, yuav tsum muaj plaub yam: ua ntej, cov yeeb yaj kiab yuav tsum muaj tag nrho HD; thib ob, cov zaub xav tau kev txhawb nqa puv HD; thib peb, lub dot pitch ntawm LED zaub yog txo; thiab qhov thib plaub yog kev sib txuas ntawm LED zaub thiab video processor.
1. Kev txhim kho qhov sib piv ntawm LED puv-xim zaub screen yog ib qho tseem ceeb cuam tshuam rau qhov pom kev zoo. Feem ntau hais lus, qhov siab dua qhov sib piv, qhov pom tseeb dua cov duab thiab cov xim ci dua. High contrast yog pab tau heev rau cov duab clarity, nthuav dav kev ua tau zoo, thiab grayscale 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, qhov zoo sib xws ntawm cov xim puv xim LED muaj qhov zoo ntawm qhov sib piv xim dub thiab dawb, qhov ntse, thiab kev ncaj ncees. Qhov sib piv muaj qhov cuam tshuam ntau dua rau cov txiaj ntsig ntawm cov yeeb yaj kiab dynamic. Vim tias qhov hloov pauv ntawm lub teeb thiab tsaus nti hauv cov duab dynamic yog qhov nrawm, qhov sib txawv ntau dua, qhov yooj yim dua rau tib neeg lub qhov muag kom paub qhov txawv ntawm txoj kev hloov pauv. Qhov tseeb, kev txhim kho ntawm qhov sib piv ntawm LED puv xim npo yog tsuas yog los txhim kho qhov ci ntsa iab ntawm tag nrho cov xim LED zaub 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, tab sis kuj ua rau lub teeb paug. Lub teeb muaj kuab paug tau dhau los ua lub ntsiab lus kub tam sim no, thiab qhov ci ci siab yuav muaj kev cuam tshuam rau ib puag ncig thiab tib neeg. Cov xim puv xim LED zaub LED vaj huam sib luag thiab LED lub teeb-emitting raj tau ua haujlwm tshwj xeeb, uas tuaj yeem txo qhov cuam tshuam ntawm LED vaj huam sib luag thiab txhim kho qhov sib piv ntawm cov xim puv xim LED.

2. Txhim kho qib grey ntawm LED puv xim zaub Cov qib grey hais txog qib ci ci uas tuaj yeem txawv ntawm qhov tsaus ntuj mus rau qhov ci tshaj plaws nyob rau hauv ib qho xim ci ntawm LED puv xim npo. Grey theem ntawm lubSandsLED puv xim LED zaubyog siab dua. Siab, cov xim nplua nuj, xim ci dua; ntawm qhov tsis sib xws, cov xim zaub yog ib leeg thiab qhov kev hloov pauv yog qhov yooj yim. Kev txhim kho ntawm qib grey tuaj yeem txhim kho qhov tob xim zoo nkauj, yog li cov duab qib ntawm cov duab xim nce geometrically. Lub LED grayscale tswj theem yog 14-16 ntsis, uas 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 cuab yeej cuab tam, LED grey nplai yuav txuas ntxiv txhim kho kom muaj kev tswj xyuas siab dua.

3. Txo qhov dot pitch ntawm cov xim puv xim LED Qhov me me ntawm cov dot pitch ntawm cov xim puv xim LED, qhov muag pom ntau dua. Txawm li cas los xij, qhov taw tes no yuav tsum tau txhawb nqa los ntawm cov cuab yeej paub tab. Nws cov 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 tab tom txhim kho rau me me-pitch LED zaub.

4. Kev sib xyaw ua ke ntawm LED puv xim zaub screen thiab video processor Lub 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, motion them, thiab lwm yam. , txhawm rau txhim kho cov duab zoo. paub meej thiab txhim kho cov duab zoo. Cov video processor duab scaling processing algorithm yog siv los xyuas kom meej tias tom qab daim duab yees duab yog scaled, lub clarity thiab grey theem ntawm daim duab yog tswj kom loj tshaj. Tsis tas li ntawd, tus txheej txheem video kuj yuav tsum muaj cov duab nplua nuj kev xaiv thiab hloov cov teebmeem, thiab ua cov duab ci ntsa iab, qhov sib piv, thiab greyscale kom ntseeg tau tias lub vijtsam tso tawm cov duab mos thiab meej.
