1. Lub teeb-emitting Cheebtsam
LED tag nrho-xim zaub lub teeb-emitting ntsiab, uas yog LED teeb-emitting raj, inconsistent brightness nyob rau hauv cov txheej txheem ntau lawm yog inevitable. Txawm li cas los xij, qhov kev ntsuas tau txais los ntawm LED cov khoom siv hluav taws xob ua lag luam yog ua kom muaj kev faib tawm tom qab tsim khoom tiav. Qhov me me qhov sib txawv ntawm qhov sib txawv ntawm ob cov ntaub ntawv nyob ib sab, qhov zoo dua qhov sib xws, tab sis cov tsos ntawm cov khoom qis thiab cov khoom muag siab yuav hnyav dua. Yog li ntawd, txhua tus neeg tsim khoom tswj qhov ci ntsa iab ntawm ob lub zog uas nyob ib sab ntawm 20%.
2. Tsav cov khoom siv
LED tag nrho-xim zaub tsav Cheebtsam feem ntau yog cov tsav tam sim no, xws li MBl5026 thiab lwm yam. Cov chips no suav nrog 16 qhov tso tawm tam sim no tsis tu ncua, uas tuaj yeem siv los teeb tsa tus nqi tso tawm tam sim no. Qhov yuam kev ntawm txhua qhov tso zis ntawm tib lub nti yog tswj tsis pub dhau 3%, thiab qhov kev ua yuam kev ntawm cov chips sib txawv yog tswj tsis pub dhau 6%. Nws yog ib txwm ua rau LED puv-xim zaub kom pom qhov ci tsis raug ntawm 25% ntawm pixels. Yog tias lub raj LED siv tsis yog tib theem thiab hom puv xim LED zaub, qhov ci ntsa iab yuav nce mus rau ntau dua 40%.
Tsis tas li ntawd, nws tsim nyog sau cia tias qhov tsis sib xws ntawm qhov ci ntawm cov xim puv xim LED yog qhov laj thawj tseem ceeb rau kev tsim ntawm lub vijtsam. Nws tsis tuaj yeem raug kho los ntawm cov khoom siv pov thawj tom qab, tsuav nws tau pom los ntawm LED cov chaw tsim khoom thaum lub sijhawm tsim khoom thiab tsim khoom. Yog li ntawd, yog tias koj yuav ib lub vijtsam nrog qhov ci tsis sib xws, thov hu rau koj tus neeg muab kev pabcuam lossis cov chaw tsim khoom los daws qhov teeb meem.
3. Cov zaub yog tov nrog cov ntaub ntawv thaum lub sij hawm tsim khoom, thiab sib txawv batches ntawm dot matrix yog siv.
Yuav daws qhov sib txawv xim ntawm LED hluav taws xob li cas?
Thawj txoj hauv kev yog hloov cov tam sim no ntws los ntawm LED. Feem ntau, kev ua haujlwm tsis tu ncua ntawm lub raj LED tau tso cai yog li 20 mA. Tsuas yog qhov saturation ntawm LED liab, lub ci ci ntawm lwm cov LEDs yog qhov sib piv rau qhov ntws tam sim no;
Qhov thib ob txoj kev: siv qhov muag pom inertia ntawm tib neeg lub qhov muag, lub pulse width modulation method yog siv los ua kom tiav grey scale tswj, uas yog, lub teeb mem tes dav hloov pauv ib ntus.
