Ua ntej ntawm tag nrho cov, peb yuav tsum to taub dab tsi yog "dej ripple" ntawm cov zaub? Nws lub npe scientific tseem hu ua: "Moore pattern". Thaum peb siv lub koob yees duab digital los tua qhov xwm txheej, yog tias muaj dej ntws tsawg, tsis muaj dej ntws ib yam li tshwm sim. Qhov no yog moiré. Cias muab, moiré yog ib qho kev tshwm sim ntawm txoj cai tuav. Kev ua lej, thaum ob qhov sib npaug-amplitude sine waves nrog ze frequencies yog superimposed, lub amplitude ntawm lub teeb liab tshwm sim yuav txawv raws li qhov sib txawv ntawm ob zaus.
Vim li cas ripples tshwm?
1. Lub LED zaub tau muab faib ua ob hom: high-refresh thiab normal-refresh. Lub siab refresh tus nqi zaub tuaj yeem ncav cuag 3840Hz / s, thiab tus nqi refresh yog 1920Hz / s. Thaum ua yeeb yaj kiab thiab duab, cov ntxaij vab tshaus siab thiab ib txwm ua kom rov zoo li qub yuav luag tsis paub qhov txawv ntawm qhov muag liab qab, tab sis lawv tuaj yeem paub qhov txawv ntawm cov xov tooj ntawm tes thiab lub koob yees duab siab.
2. Lub vijtsam LED nrog cov kev hloov tshiab tsis tu ncua yuav muaj cov dej ripples pom tseeb thaum thaij duab nrog lub xov tooj ntawm tes, thiab lub vijtsam zoo li flickering, thaum lub vijtsam nrog lub siab refresh yuav tsis muaj dej ripples.
3. Yog tias qhov yuav tsum tau ua tsis siab lossis tsis muaj qhov yuav tsum tau tua, koj tuaj yeem siv qhov kev hloov pauv hloov tshiab coj lub vijtsam, qhov sib txawv ntawm qhov muag liab qab tsis loj, cov nyhuv yog ok, thiab tus nqi pheej yig. Tus nqi ntawm tus nqi siab refresh thiab tus nqi hloov tshiab tsis tu ncua yog qhov sib txawv heev, thiab kev xaiv tshwj xeeb yog nyob ntawm cov neeg siv khoom xav tau thiab peev nyiaj txiag.
Qhov zoo ntawm kev xaiv lub refresh npaum li cas LED zaub
1. Tus nqi refresh yog qhov ceev ntawm qhov screen yog refreshed. Tus nqi refresh yog ntau tshaj 3840 zaug ib ob, uas peb hu ua siab refresh;
2. Siab refresh npaum li cas tsis yooj yim los tshwm smear phenomenon;
3. Cov nyhuv yees duab ntawm lub xov tooj ntawm tes lossis lub koob yees duab tuaj yeem txo qhov tshwm sim ntawm cov dej ripples, thiab nws zoo li daim iav;
4. Daim duab kev ntxhib los mos yog qhov tseeb thiab muag heev, cov xim yog vivid, thiab qib ntawm kev txo qis yog siab;
5. Lub siab refresh tus nqi zaub yog qhov muag-phooj ywg thiab xis dua;
Flickering thiab jittering tuaj yeem ua rau mob qhov muag, thiab kev saib ntev ntev tuaj yeem ua rau mob qhov muag. Qhov siab dua qhov refresh npaum li cas, qhov kev puas tsuaj tsawg dua rau qhov muag;
6. High refresh npaum li cas LED zaub yog siv nyob rau hauv lub rooj sib tham, chaw hais kom ua, exhibition halls, ntse nroog, ntse tsev kawm ntawv, tsev cia puav pheej, tub rog, tsev kho mob, gymnasiums, tsev so thiab lwm qhov chaw los qhia txog qhov tseem ceeb ntawm lawv txoj haujlwm.
