Yuav ua li cas yog Zoo piv (CR)?

Apr 10, 2017

Zoo ratio (CR) yog tus piv ntawm luminance ntawm lub brightest "dawb" thiab cov darkest "dub" uas yuav tau ua nyob rau hauv ib tug zaub. CR yog lwm tus ntawm dab tsi daim duab zoo. Yog hais tias ib daim duab muaj siab CR, koj yuav xav txog nws mus yuav sharper thiab crisper tshaj ib daim duab nrog qis CR. Piv txwv li, ib tug raug cov ntawv xov xwm duab muaj ib tug CR ntawm hais txog 5 rau 7, whereas ib tug zoo magazine daim duab muaj ib tug CR uas yog ntau tshaj 15. Yog li ntawd, lub magazine daim duab yuav zoo zoo txawm yog hais tias tus kev daws teeb meem yog tib yam li hais tias ntawm lub ntawv xov xwm duab.

Ib tug raug AMLCD exhibits ib CR ntawm kwv yees li 300 mus 700 thaum ntsuas nyob rau hauv ib chav tsev tsaus. Lub CR rau tib chav tsev ntsuas nyob rau hauv ambient illumination yog ruaj txo qis vim nto thiaj (glare). Piv txwv li, ib tug txheej txheem 200 qe ntshauv LCD ntsuas nyob rau hauv ib chav tsev tsaus muaj ib tug 300 CR, tiam sis yuav muaj tsawg tshaj li ib 2.0 CR nyob rau hauv khaus ncaj qha tshav ntuj. Qhov no yog vim lub fact tias nto glare tsub kom lub luminance los ntawm ntau tshaj 200 cov qe ntshauv ob leeg rau lub "dawb" thiab cov "dub" uas yog ua rau ntawm cov zaub screen. Cov no luminance ntawm cov dawb yog me ntsis tshaj 400 cov qe ntshauv, thiab cov luminance ntawm cov dub lawm 200 qe. Lub CR piv ces yuav tsawg tshaj li 2 thiab cov duab zoo yog ruaj txo thiab tsis tau.
