Pane nzira mbiri dzekudzora kupenya kwemukati-yakazara-ruvara LED kuratidza:

1. Shandura ikozvino kuburikidza nemukati yakazara-ruvara rwe LED kuratidza.Kazhinji, iyo LED chubhu inogona kushanda nguva dzose kweinenge 20ma.Pamusoro pekuzara kweiyo dzvuku LED, kupenya kweiyo LED kunonyanya kuenderana neyazvino.

2. Shandisa inertia yekuona kwemunhu kuona grey-scale control ye pulse width modulation, kureva kuti, nguva nenguva shandura chiedza chepulse width (kureva, basa rekutenderera).Chero bedzi iyo yekuzorodza frequency yakakwira zvakakwana, maziso emunhu haazonzwa kuzununguka kwechiedza-emitting pixels.Nekuti pulse wide modulation inonyanya kukodzera kudzora dhijitari, mamicrocomputer anowanzo shandiswa kupa LED kuratidza zvemukati.Anenge ese emukati-akazara-ruvara LED anoratidza anoshandisa pulse wide modulation kudzora greyscale.

Kupenya kwemukati-yakazara-ruvara rwe LED kuratidza kunofanirwa kusvika 1500cd/m2 kana kupfuura kuti ive nechokwadi chekutamba kwakajairika kwemukati-yakazara-ruvara LED kuratidza.Zvikasadaro, chifananidzo chinoratidzwa hachizove chakajeka nekuda kwekupenya kwakaderera, asi akawanda emukati-yakazara-ruvara LED anoratidza Kupenya kunopfuura 5000cd/m2, uye iyo yekutamba mhedzisiro yakanaka kwazvo mukati mezuva, asi kupenya kwakakwirira kwakadaro kuchakonzera kusvibiswa kwakakomba kwechiedza. usiku.

Iyo iripo software inogadzirisa kupenya, kazhinji inotora 256-level kugadzirisa nzira.Muchokwadi, iyo software inongova yekushanda interface.Kuburikidza nekushanda kwesoftware, iyo PWM yebasa kutenderera kweiyo yakazara-ruvara LED kuratidza mutyairi inoshandurwa kuti ione shanduko yekupenya.

Kupenya kwemukati-yakazara-ruvara rwe LED kuratidza kunobatsira zvakanyanya kune LED skrini.Kugadzirisa kupenya kuburikidza nesoftware inzira yekutanga uye tsika muindasitiri, uye inoonekwa senzira inoshanda.Kazhinji, mushure meiyo yemukati yakazara-ruvara yekuratidzira LED purojekiti yapedzwa, vagadziri Kudzidziswa kwakakosha kunopihwa kune software, chinangwa ndechekubatsira vatengi kutanga bhizinesi nekukurumidza sezvinobvira.
