Ndezvipi zvikamu zvikuru zve led display screen?Kune akawanda ma LED anoratidza vagadziri pamusika, uye mutengo wemhando imwechete yekuratidzira kwe LED uchiri wakasiyana.Chikamu chikuru chechikonzero chiri muzvikamu zvayo.Hunhu uye mutengo weyuniti yezvinhu izvi zvimiro zvinokanganisa mutengo wekupedzisira wekuratidzira kwe LED.Titevere nhasi Ngatitarisei zvikamu zveiyo led kuratidza:
1. Unit board
Iyo unit board ndechimwe chezvikamu zvakakosha zveiyo led kuratidza.Hunhu hwebhodhi bhodhi huchakanganisa zvakananga kuratidzwa kweiyo led kuratidza.Iyo unit board inoumbwa neiyo led module, mutyairi chip uye pcb redunhu bhodhi.Iyo led module inoumbwa nevakawanda Iyo LED light-emitting point inoputirwa neresin kana plastiki;
Iyo mutyairi chip inonyanya 74HC59574HC245/24474HC1384953.
Iwo anowanzo shandiswa bhodhi bhodhi zvirevo zvemukati led skrini ndeaya:
Parameter D=3.75;dot pitch 4.75mm, dot width * 16 dot urefu, 1/16 tsvaira kupenya kwemukati, imwechete tsvuku / tsvuku uye girini mavara maviri;
Parameter tsananguro
D inomiririra dhayamita inopenya, iyo inoreva dhayamita yenzvimbo inopenya D = 3.75mm;
Chiedza-emitting point kureba ndeye 4.75mm, zvichienderana nekutarisa kure kwemushandisi, yemukati chiitiko kazhinji inosarudza 4.75;
Saizi yebhodhi yeyuniti ndeye 64 * 16, iyo inonyanya kushandiswa bhodhi bhodhi, iyo iri nyore kutenga uye mutengo wakaderera;
1/16 kutsvaira, nzira yekudzora yeyuniti bhodhi;
Kupenya kwemukati kunoreva kupenya kwemwenje we LED-emitting, uye kupenya kwemukati kwakakodzera kunharaunda inoda kuvhenekerwa nemwenje wefluorescent masikati;
Rudzi, ruvara rumwechete runonyanya kushandiswa, uye mutengo wacho wakachipa, maviri-mavara anowanzoreva tsvuku uye girini, uye mutengo uchave wakakwira zvishoma;
Ngatiti iwe unoda kuita 128 * 16 skrini, ingobatanidza mabhodhi maviri eyuniti munhevedzano;
2. Simba
Kazhinji, kushandura magetsi kunoshandiswa, 220v kupinza, 5v DC inobuda, asi zvinofanirwa kucherechedzwa pano kuti nekuti iyo inotungamira ratidziro ndeye yakaomesesa yemagetsi mudziyo, zvinodikanwa kushandisa switching magetsi panzvimbo ye transformer.Kune imwechete tsvuku yemukati 64 * 16 Kana iyo unit board yakanyatso kupenya, ikozvino ndeye 2a;inogona kufananidzwa kuti ikozvino ye128 * 16-mavara maviri-mavara skrini ndeye 8a mumamiriro ezvinhu akajeka, uye 5v10a inoshandura magetsi inofanira kusarudzwa;
3. Kudzora kadhi
Isu tinokurudzira kushandisa yakaderera-mutengo strip screen control kadhi, iyo inogona kudzora 256 * 16-dot maviri-mavara skrini ine 1/16 scan, uye inogona kuunganidza LED skrini ine mutengo wepamusoro mukana.Kadhi yekudzora iasynchronous kadhi, kureva kuti, Kadhi inogona kuchengetedza ruzivo mushure mekudzima simba, uye inogona kuratidza ruzivo rwakachengetwa mairi pasina kubatana nekombuta.Paunenge uchitenga bhodhi reyuniti, unofanirwa kubvunza ma parameter.Iyo inoenderana zvizere yeyuniti board inonyanya kuve ne 08 interface, 4.75mm point kureba, 64 points yakafara uye 16 points kumusoro., 1/16 scan indoor kupenya, imwechete tsvuku / tsvuku uye girini mavara maviri;08 interface 7.62mm point chinhambwe 64 mapoinzi yakafara * 16 mapoinzi kumusoro, 1/16 scan kupenya kwemukati, imwechete tsvuku / tsvuku uye girini mavara maviri;08 interface 7.62 mapoinzi chinhambwe 64 mapoinzi Upamhi * 16 mapoinzi kureba, 1/16 hafu-kutsvaira kwekunze kupenya, imwechete tsvuku / tsvuku uye girinhi mbiri-ruvara;
4. Nezve 16PIN08 interface
Nekuti kune vazhinji vanogadzira mabhodhi eunit uye makadhi ekudzora, kune akawanda masitayipi eiyo unit board.Paunenge uchiunganidza iyo LED skrini, zvinodikanwa kusimbisa kuenderana kweiyo interface kufambisa gungano.Pano isu tinosuma iyo inowanzo shandiswa LED interfaces: led Indasitiri nhamba: 16PIN08 interface, iyo interface inoteedzana ndeiyi inotevera: 2ABCDG1G2STBCLK16

ABCD chiratidzo chekusarudza mutsara, STB chiratidzo chelatch, CLK chiratidzo chewachi, R1, R2, G1, G2 ndiyo data yekuratidzira, EN ibasa rekuratidzira, uye N ivhu.Ita shuwa kuti iyo yekubatanidza pakati peyuniti bhodhi uye kadhi yekudzora yakafanana uye inogona kubatanidzwa zvakananga Kana isingaenderane, iwe unofanirwa kuita mutsara wekushandura iwe pachako kuti uchinje kurongeka kwemitsara;
5. Mutsara wekubatanidza
Inonyanya kukamurwa kuita mutsara wedata, mutsara wekutumira, tambo yemagetsi, mutsara wedata unonyanya kushandiswa kubatanidza kadhi rekutonga uye LED unit board, mutsara wekutumira unoshandiswa kubatanidza kadhi rekutonga nekombuta, tambo yemagetsi inoshandiswa kubatanidza. iyo magetsi uye kadhi rekutonga simba rekupa uye bhodhi rinotungamirira bhodhi, mhangura yemhangura yetambo yemagetsi inobatanidza chikwata chebhodhi haifaniri kunge iri pasi pe1mm muhupamhi;
Izvo zviri pamusoro ndizvo zvikamu zvechimiro cheiyo yakazara-ruvara LED kuratidza.Muchidimbu, pane kunyanya mabhodhi echikwata, magetsi emagetsi, makadhi ekudzora, mitsara yekubatanidza, nezvimwewo. Ndinovimba kuti chinyorwa ichi chinogona kukubatsira.Kana iwe uchida kuziva zvakawanda nezve chimiro cheiyo LED kuratidza ruzivo, unogamuchirwa kuti urambe uchiteerera.
