Muaj ob txoj hauv kev los tswj qhov ci ntawm sab hauv tsev puv xim LED zaub:

1. Hloov tam sim no los ntawm sab hauv tsev puv xim LED zaub.Feem ntau, lub raj LED tuaj yeem ua haujlwm tsis tu ncua txog li 20ma.Ntxiv nrog rau qhov saturation ntawm liab LED, lub ci ci ntawm LED yog qhov sib piv rau qhov tam sim no.

2. Siv lub inertia ntawm tib neeg lub zeem muag kom paub qhov grey-scale tswj ntawm mem tes dav modulation, uas yog, lub sij hawm hloov lub teeb mem tes dav (uas yog, lub luag hauj lwm voj voog).Ntev npaum li qhov refresh zaus siab txaus, tib neeg lub qhov muag yuav tsis hnov ​​​​qhov co ntawm lub teeb-emitting pixels.Vim tias pulse width modulation yog tsim nyog rau kev tswj digital, microcomputers feem ntau yog siv los muab cov ntsiab lus ntawm LED.Yuav luag tag nrho cov xim sab hauv tsev LED qhia siv pulse dav modulation los tswj grayscale.

Lub ci ci ntawm sab hauv tsev puv xim LED zaub yuav tsum ncav cuag 1500cd / m2 los yog ntau dua kom ntseeg tau tias qhov kev ua si ib txwm muaj ntawm sab hauv tsev puv xim LED zaub.Txwv tsis pub, cov duab tso tawm yuav tsis pom meej vim qhov ci ntsa iab, tab sis ntau cov xim sab hauv LED pom Lub ci ci siab tshaj 5000cd / m2, thiab cov nyhuv playback zoo heev thaum nruab hnub, tab sis qhov ci ci no yuav ua rau muaj teeb meem loj. hmo ntuj.

Cov software uas twb muaj lawm kho qhov ci ntsa iab, feem ntau siv 256-theem kev hloov kho.Qhov tseeb, lub software tsuas yog kev ua haujlwm interface.Los ntawm kev ua haujlwm software, PWM lub luag haujlwm lub voj voog ntawm cov xim puv xim LED tsav tsheb tau hloov pauv kom paub txog qhov ci ntsa iab.

Qhov ci ntsa iab ntawm sab hauv tsev puv xim LED zaub yog qhov tseem ceeb heev rau cov ntxaij vab tshaus LED.Kho qhov ci ci los ntawm software yog ib txoj hauv kev yooj yim thiab kev coj ua hauv kev lag luam, thiab suav tias yog ib txoj hauv kev zoo.Feem ntau, tom qab lub teeb pom kev zoo sab hauv tsev ua tiav, cov chaw tsim khoom tshwj xeeb yuav muab kev cob qhia rau software, lub hom phiaj yog los pab cov neeg siv khoom pib ua lag luam sai li sai tau.
