Luam theej duab hom rau zaub LED yog dab tsi?

Scanning hom kev LED zaub totaub ntau tus neeg, dab tsi tau yuav nws ua hauj lwm? Thiab qhov muaj kev tshuaj ntsuam LED yog dab tsi? No muab koj yam lus:
Txhais hais tias LED uas tus neeg tsav yog/Hmong IC,
txhais tau tias LED yog rho tawm hauj lwm.
Txhua tsav/Hmong IC muaj 16 pins, thiab yuav tsav 16 LED nti tsawg tshaj. Zoo li qub tsav hom txhais tau hais tias tag nrho cov kev LEDs hauv lub LED module no uas tau tsav ua/Hmong IC txhua lub sij hawm, xws li cov duab hauv qab no:

hom 1/12 scan, txhais tau hais tias 1/12 LEDs rau lub module no uas tau tsav ua/Hmong IC hauv ua ke, thiab lwm lub sij hawm muaj ntau lwm 1/12 LEDs no uas tau tsav.

hom 1/6 scan, txhais tau hais tias 1/6 LEDs txog cov module no uas tau tsav ua/Hmong IC hauv ua ke, thiab lwm lub sij hawm muaj ntau lwm 1/6 LEDs no uas tau tsav.

Ceeb toom: Vim hom scan hloov luam theej duab kab mob ceev ceev, thiab distinguished tsis raws tib neeg qhov muag, ces hauv visually, peb xav tias tus LEDs teeb rau txhua lub sij hawm muaj, tab sis qhov tseeb, scan hom LEDs tawm thaum twg peb pom nws.
Yog li, scan tsawg hom yuav txuag tsav/Hmong IC, es tseg cov nqi. Tab sis zoo li cas ntawv nws muaj feem xyuam rau qhov LED screen?
1) brightness: Lub High School luam theej duab LEDs nti pom ntau rau hauv ua ke, ces cov brightness muaj ntau dua sab scan hom, hauv kev tshawb xav, rau tus qub LED zaub, scan zoo li qub coj brightness txog rau 1/2 scan, thiab 1/4 scan ob chav brightness ntawm 1/8 scan. Tiamsis qhov no yog ib qho tsis tsis noj mis nyuj tov, vim tej tsam muaj tsis yuav tsum brightness heev, thiab yuav tsis cia qhov chaw, thiab thaum kawg hlais lub brightness.
(2) refresh feem: feem ntau txo scan nrog sab twg refresh dua qhov yooj yim dua scan. Thiab qhov no yog tsis muaj xws li cov mis mos ntau li brightness, vim cov refresh tus nqi mas vam khom cov PCB tsim.
(3) cov hwj huam haus: ziag, qhov yooj yim dua scan, cov hwj huam dua, qhov no yog muaj feem xyuam ntau hom mis, rau piv txwv 1/5 scan yog fais fab coj haus ntawm scan 1/10. Ntxiv mus, nws caiv los ntawm cov chaw, factories yuav txo qhov tam sim no thiab thaum kawg txo hwjchim thiab brightness.
Vim li no, nws tseem ceeb heev yuav xaiv ib tug tsim nyog scan hom rau coj tso saib, tsis siab tshaj ntawd nws yuav zoo dua, kuj tsis converse. Nws xav tau los ntawm tus brightness, muaj hwj huam, refresh npaum li cas thiab nqi, thaum kawg tsim ib cov tshuaj ntsuam LED zoo.
