Peb yam tseem ceeb cuam tshuam rau qhov pom tseeb ntawm tag nrho -xim LED zaub screen yog qhov sib piv piv, pixel suab, thiab qib grey. Ib qho kev ntsuam xyuas ntxaws nram qab no:
Contrast Ratio: Qhov sib piv piv yog qhov tseem ceeb cuam tshuam rau qhov pom kev pom. Qhov sib piv ntau dua ua rau cov duab pom meej dua, nthuav dav, thiab qib greyscale. High contrast ratio tso cai rau tag nrho - xim LED qhia kom nthuav tawm cov npoo ntse dua thiab cov duab tiav ntau dua thaum tso cov ntawv lossis cov yeeb yaj kiab nrog cov xim dub siab -thiab- dawb sib piv. Rau cov yeeb yaj kiab dynamic, qhov sib piv siab ua kom pom kev pom ntawm lub teeb thiab tsaus ntuj, ua kom hloov cov ntsiab lus yooj yim rau qhov muag liab qab kom pom. Piv txwv li, thaum ua yeeb yaj kiab nrog ceev ceev- txav scenes lossis teeb pom kev zoo hloov pauv, qhov sib piv siab zoo txo cov duab plooj thiab txhim kho qhov tseeb ntawm qhov pom kev.
Pixel Pitch: Pixel suab hais txog qhov chaw nruab nrab - mus rau - nruab nrab ntawm qhov nrug ntawm cov pixels uas nyob ib sab ntawm qhov puv - xim LED zaub screen thiab yog qhov tseem ceeb parameter txiav txim siab theem ntawm kev nthuav dav hauv daim duab. Ib qho pixel me me ua rau muaj qhov siab dua pixel ntom ntawm ib cheeb tsam ib cheeb tsam, cov duab ua kom zoo dua qub, thiab tsis tshua pom cov graininess thaum saib ze. Piv txwv li, P2.5 (2.5mm pixel suab) tso saib cov ntawv qhia cov ntawv lossis cov duab nrog cov npoo smoother dua li P5 (5mm pixel suab) npo. Txawm li cas los xij, kev txo cov pixel suab yuav tsum muaj kev txhawb nqa thev naus laus zis, xws li siab - cov txheej txheem ntim cov txheej txheem thiab cov chips tsav tsheb, uas ua rau cov nqi ntau lawm thiab cov nqi khoom ntau dua. Tam sim no, kev ua lag luam tau maj mam txav mus rau qhov me me pixel pitch LED zaub (xws li hauv qab P1.0) kom ua tau raws li qhov kev thov rau ultra{13}} siab- txhais cov lus qhia hauv siab - kawg scenarios.
Greyscale yog hais txog tus naj npawb ntawm qhov sib txawv qhov ci ci rau ib qho xim thawj (liab, ntsuab, thiab xiav) nyob rau hauv tag nrho -xim LED zaub, los ntawm nws qhov tsaus ntuj tshaj plaws rau nws qhov ci tshaj plaws. Cov qib grayscale siab dua ua rau cov xim hloov pauv ntau dua thiab cov xim zoo dua. Piv txwv li, 14-me ntsis greyscale tuaj yeem txhawb 16384 qib ntawm qhov ci variation, ua rau cov duab pom ze rau qhov tiag- xim gradations ntiaj teb. Cov lus qhia siab kawg ua tiav cov xim zoo nkauj dua los ntawm kev txhim kho greyscale tswj qhov tseeb (xws li 16-ntsis), tshwj xeeb tshaj yog thaum pom cov gradients nyuaj lossis cov ntsiab lus tsaus. Nrog rau kev nce qib hauv kev siv thev naus laus zis thev naus laus zis, qib greyscale tab tom txhim kho mus rau qhov siab dua (xws li 18-ntsis), ntxiv kev ua kom pom cov teebmeem zoo dua.
