Vim tias LEDs yog kev taw qhia, tag nrho - xim LED cov lus tseem muaj cov khoom taw qhia, txhais tau tias lawv qhov ci nce lossis txo qis nyob ntawm qhov pom lub kaum ntse ntse. Yog li ntawd, qhov sib xws ntawm cov xim liab, ntsuab, thiab xiav LEDs cuam tshuam rau qhov sib npaug ntawm qhov sib npaug ntawm cov ces kaum sib txawv, cuam tshuam ncaj qha rau cov xim fidelity ntawm cov zaub. Txhawm rau kom ua tiav qhov ci ntsa iab zoo sib xws rau cov xim liab, ntsuab, thiab xiav LEDs ntawm cov ces kaum sib txawv, kev tsim kev tshawb fawb nruj heev yuav tsum muaj nyob rau hauv lub ntim ntim lub lens tsim thiab xaiv cov khoom siv, uas yog nyob ntawm cov txheej txheem ntawm cov khoom ntim khoom.
High-cov lus txhais cov yeeb yaj kiab feem ntau muab qhov kev paub pom zoo tshaj plaws, thiab cov ntsiab lus tso tawm yog qhov tseeb dua. Kev ua tiav siab - cov lus txhais lus yuav tsum muaj ob yam: thawj, cov khoom siv yuav tsum yog tag nrho HD, thiab thib ob, cov zaub yuav tsum txhawb nqa tag nrho HD. Tag nrho -xim LED zaub kuj tseem txav mus rau cov ntsiab lus siab dua. Yog li, peb tuaj yeem txhim kho qhov pom tseeb ntawm tag nrho -xim LED zaub? Cia peb muaj kev tsom xam luv luv los ntawm peb cov phooj ywg ntawm Tuam Tshoj LED Engineering Alliance.
Ua ntej, txhim kho qhov sib piv ntawm tag nrho - xim LED zaub. Qhov sib txawv yog ib qho tseem ceeb cuam tshuam rau kev pom kev pom. Feem ntau, qhov siab dua qhov sib piv, qhov pom tseeb thiab pom ntau dua cov duab, thiab cov xim zoo nkauj thiab vibrant. High contrast yog pab tau heev rau cov duab clarity, nthuav dav sawv cev, thiab grayscale sawv cev.
Nyob rau hauv cov ntawv nyeem thiab video qhia nrog siab dub thiab dawb sib piv, siab - sib piv tag nrho - xim LED zaub muaj qhov zoo ntawm qhov sib piv dub thiab dawb, pom tseeb, thiab ua tiav. Qhov sib piv muaj qhov cuam tshuam ntau dua rau cov txiaj ntsig ntawm cov yeeb yaj kiab dynamic. Vim hais tias lub teeb thiab tsaus nti hloov nyob rau hauv dynamic dluab yog ceev ceev, qhov siab dua qhov sib piv, nws yog qhov yooj yim dua rau tib neeg lub qhov muag kom paub qhov txawv ntawm cov kev hloov no.
Qhov tseeb, kev txhim kho qhov sib piv ntawm tag nrho -xim LED zaub feem ntau yog ua kom qhov ci ntawm tag nrho -xim LED zaub thiab txo qhov cuam tshuam ntawm qhov screen. Txawm li cas los xij, qhov ci ci siab dua tsis yog ib txwm zoo dua; siab dhau qhov ci tuaj yeem ua rau muaj teeb meem. Lub teeb muaj kuab paug yog lub ntsiab lus kub tam sim no, thiab qhov ci ci ntau dhau tuaj yeem cuam tshuam rau ib puag ncig thiab tib neeg. Kev ua haujlwm tshwj xeeb ntawm LED vaj huam sib luag thiab LED teeb-emitting diodes ntawm tag nrho -xim LED zaub tuaj yeem txo qhov kev xav ntawm LED vaj huam sib luag thiab kuj txhim kho qhov sib piv ntawm tag nrho - xim LED zaub. Thib ob, nce qib grey nplai ntawm tag nrho -xim LED cov duab txhim kho cov duab zoo. Grayscale theem yog hais txog tus naj npawb ntawm qhov sib txawv qhov ci ntawm qhov tsaus ntuj mus rau qhov ci tshaj plaws rau ib qho xim thawj hauv tag nrho - xim LED zaub. Qhov siab dua ntawm qib grey ntawm tag nrho - xim LED zaub, cov xim nplua nuj dua thiab muaj zog dua; conversely, qib qis grayscale ua rau yooj yim dua, tsawg varied xim. Kev nce qib grayscale ho txhim kho xim qhov tob, geometrically nce tus naj npawb ntawm cov xim xim. Nrog rau kev nce qib ntawm cov cuab yeej siv thev naus laus zis, LED qib grey nplai yuav txuas ntxiv txhim kho mus rau kev tswj xyuas siab dua.
Thaum kawg, txo cov pixel suab ntawm tag nrho - xim LED zaub tuaj yeem txhim kho qhov pom tseeb. Qhov me me pixel suab ntawm tag nrho - xim LED zaub, qhov zoo dua cov duab zaub. Txawm li cas los xij, qhov no yuav tsum muaj cov cuab yeej paub tab raws li kev txhawb nqa tseem ceeb, thiab tus nqi peev yog qhov siab, ua rau tus nqi siab dua rau qhov ua tiav tag nrho - xim LED zaub. Hmoov zoo, kev ua lag luam tam sim no tsiv mus rau me me -pitch LED zaub. Piv txwv li, Easystar tus kheej tsim me me -pitch cov khoom tau coj qhov pom tseeb ntawm LED zaub mus rau qib tshiab.
