Mumakore achangopfuura, iyo LED yemagetsi kuratidza musika yave yakakurumbira, ichityaira iyo yese LED kuratidza indasitiri mudanho rekukura nekukurumidza.Pamusoro pezviratidziro zvekushambadzira, zvikirini zvemitambo, uye zviratidziro zvetraffic ekutungamira anoshandiswa zvakanyanya kunze, emukati ma LED maratidziro zvakare musika une hukuru hukuru, kusanganisira mahombe emukati ekutarisa masikirini uye emukati emagetsi machira emaketeni.Asi kubva pakuona kwehunyanzvi, chokwadi, mumakore gumi apfuura kana zvakadaro, zviratidziro zve LED zvakaunzwa nevazhinji vagadziri hazvina kushanduka zvakanyanya muhurongwa hwekuvaka, asi zvakagadziridzwa kune imwe dhigirii maererano nezvimwe zviratidzo zvehunyanzvi. .Uye kururamisa.
Panguva imwecheteyo, kukwidziridzwa uye kukwidziridzwa kwezvigadzirwa zvemhando yepamusoro kuri kunonoka, kunyangwe makore mashoma apfuura, pakanga patove nekuratidzira mutyairi IC zvigadzirwa zvine PWM (Pulse Width Modulation) pamusika, uye vatori vechikamu zvakare yakabvumirana nebasa rePWM.Iyo ine mabhenefiti eiyo yepamusoro yekuzorodza mwero uye inogara iripo.Nekudaro, nekuda kwemutengo uye zvimwe zvinhu, iyo musika mugove weiyo yepamusoro-inoshanda kuratidza mutyairi ICs haisati yakakwira.Iwo mamodheru anonyanya kushandiswa pamusika (seMacroblock 5024/ 26 nezvimwewo), zvigadzirwa zvepamusoro-soro zvinonyanya kushandiswa mune mamwe ma LED skrini ekurenda misika inobhadhara zvakanyanya kunaka.
Zvisinei, nekukurumidza kukura kweShenzhen LED misika yekuratidzira, vashandisi vakawanda vatanga kuisa mberi zvakatevedzana zvezvinhu zvakaoma zve LED skrini kubva pakuona maitiro, nzira dzekutumira, nzira dzekuratidzira, uye nzira dzekutamba.Izvi zvakare zvinoita kuti zvigadzirwa zve LED Screen zvitarise mukana mutsva wekuvandudza tekinoroji, uye se "uropi" hweyese kuratidza system-LED mutyairi IC ichaita basa rakakosha.
Iyo data yekufambisa pakati peiyo LED skrini nebhodhi reamai kazhinji inotora serial data transmission (SPI), uyezve synchronously kuendesa kuratidza data uye kutonga dhata kuburikidza nechiratidzo packet multiplexing tekinoroji, asi kana mwero wekuzorodza uye kugadzirisa zvagadziriswa, Zviri nyore kukonzera bhodhoro mukufambiswa kwedata, zvichitungamira mukusagadzikana kwehurongwa.Uye zvakare, kana iyo skrini yechiratidzo che LED yakakura, tambo yekudzora inowanzorebesa, iyo inotarirwa nekukanganiswa kwemagetsi, inokanganisa kunaka kweiyo chiratidzo chekufambisa.
Kunyangwe vamwe vagadziri vakaunza midhiya mitsva yekufambisa mumakore achangopfuura, maitiro ekupa vashandisi kuita kwakanakisa uye inodhura-inoshanda zvigadzirwa mhinduro inyaya yakakosha inotambudza indasitiri.Kuti izvi zviitike, vamwe vagadziri vakaronga kuti nzira yekufambisa data ye LED kuratidza skrini inoda nekukurumidza kubva padanho repamusoro rehunyanzvi uye kuwana mhinduro nyowani.
Zvinokosha kucherechedza kuti tekinoroji yekuvandudza ma LED skrini yakabata zvese zvemaindasitiri ketani, kusanganisira kuvandudzwa kwemutyairi IC kugadzirwa kwemaitiro, iyo hardware yekutonga system, hungwaru kuvandudza kwekutonga software, nezvimwe. Izvi zvitsva zvetekinoroji zvinoda IC dhizaini. vagadziri, kudzora Vagadziri veSitimu, vagadziri vepaneru, uye kunyange vashandisi vekupedzisira vanonyatsobatanidzwa kutyora "deadlock" yeindasitiri yekushandisa.Kunyanya mukuvandudza masisitimu ekutonga, nzira yekudyidzana zviri nani neIC makambani ekugadzira kuvandudza mashandiro ehurongwa hwe LED skrini uye yakangwara nhanho yekutonga software ndiyo inonyanya kukosha.
