Vim li cas qhov ci ntawm sab nraum zoov puv xim LED zaub tsis sib haum?
Qhov zoo tshaj plaws sab nraum zoov puv xim LED zaub yuav tsum hloov mus rau qhov sib txawv ntawm qhov kub thiab txias, thiab tuaj yeem siv tau rau ntau lub sijhawm.Txhawm rau kom deb thiab ze lub teeb kom muaj txiaj ntsig zoo, tshwj xeeb tshaj yog rau kev ua yeeb yam loj, teeb pom kev zoo tshwj xeeb yuav tsum yog qhov zoo tshaj plaws kom tau raws li qhov xav tau ntawm kev ua yeeb yam theem.Tab sis qee zaum peb pom tias qhov ci ntawm LED zaub yuav tsis sib haum.Qhov no yog vim li cas?
1. Lub teeb-emitting lub teeb yog LED lub teeb-emitting raj, thiab inconsistency nyob rau hauv brightness yog inevitable thaum lub sij hawm ntau lawm txheej txheem.Txawm li cas los xij, qhov kev ntsuas coj los ntawm LED cov chaw tsim khoom lag luam yog cais tawm tom qab kev tsim khoom tiav.Qhov me me qhov sib txawv ntawm qhov sib txawv ntawm ob theem, qhov zoo dua qhov sib xws, tab sis qhov tshwm sim loj dua qhov tshwm sim ntawm cov khoom qis thiab cov khoom muag siab yuav tshwm sim.Yog li ntawd, txhua tus neeg tsim khoom tswj qhov ci ntsa iab ntawm ob lub zog uas nyob ib sab kom txog li 20%.
2. Cov khoom siv tsav tsheb feem ntau yog cov tsav tsheb tsis tu ncua, xws li MBl5026 thiab lwm yam.Cov chips no muaj 16 qhov tso tawm tam sim no tsis tu ncua, thiab cov nqi tso tawm tam sim no tuaj yeem teeb tsa nrog cov resistors.Qhov yuam kev ntawm txhua qhov tso zis ntawm tib lub nti yog tswj tsis pub dhau 3%, thiab qhov ua yuam kev ntawm cov chips sib txawv yog tswj tsis pub dhau 6%.
3. Nws yog ib txwm ua rau lub teeb ci yuam kev ntawm 25% ntawm lub pixels ntawm LED zaub screen.Yog tias LED lub teeb-emitting raj siv tsis yog tib qib thiab hom, qhov teeb meem ntawm qhov ci yuav nce mus rau ntau dua 40%.
Plaub, nws tseem tsim nyog sau cia tias qhov ci ntsa iab ntawm cov xim puv xim LED tsis sib haum, uas yog lub hauv paus ua rau qhov muag tsis pom.Yog li ntawd, yog tias koj yuav ib lub vijtsam nrog qhov ci tsis sib haum, thov hu rau koj tus neeg muab kev pabcuam lossis cov chaw tsim khoom rau kev daws teebmeem.
Cov ntsiab lus: Thaum peb ntsib qhov tsis sib xws ntawm qhov ci ntawm LED zaub, tsis tas yuav txhawj xeeb tshwj xeeb.Tsuav peb nrhiav tau txoj hauv kev kom raug thiab pom qhov teeb meem zoo, peb tuaj yeem daws cov teeb meem txawv txav zoo sib xws tau yooj yim heev.
