Yiziphi izingxenye eziyinhloko zesikrini sokubonisa esiholayo?Kunabakhiqizi abaningi be-LED emakethe, futhi intengo yohlobo olufanayo lwesibonisi se-LED isahluke kakhulu.Ingxenye enkulu yesizathu ilele ezingxenyeni zayo.Ikhwalithi nentengo yeyunithi yalezi zingxenye zesakhiwo izothinta intengo yokugcina yesibonisi se-LED.Silandele namuhla Ake sibheke izingxenye zesibonisi esiholayo:
1. Ibhodi leyunithi
Iyunithi yebhodi ingenye yezingxenye eziyinhloko zesibonisi esiholayo.Ikhwalithi yeyunithi yebhodi izothinta ngokuqondile umphumela wokubonisa wesibonisi esiholayo.Iyunithi ibhodi yakhiwe module led, chip umshayeli kanye pcb wesifunda ibhodi.I-module eholelekile empeleni yakhiwe abaningi Iphuzu elikhipha ukukhanya kwe-LED lihlanganiswe ne-resin noma ipulasitiki;
I-chip yomshayeli ikakhulukazi i-74HC59574HC245/24474HC1384953.
Ukucaciswa kwebhodi leyunithi okuvame ukusetshenziswa kwizikrini ze-indoor led yilezi:
Ipharamitha D=3.75;iphimbo lechashaza lingu-4.75mm, ububanzi bechashazi*16 ukuphakama kwamachashazi, 1/16 shanela ukukhanya kwangaphakathi, imibala emibili ebomvu/ebomvu kanye noluhlaza okotshani;
Incazelo yepharamitha
U-D umele ububanzi obukhanyayo, obubhekisela kububanzi bephoyinti elikhanyayo D=3.75mm;
Ibanga lephoyinti elikhipha ukukhanya lingu-4.75mm, ngokwebanga lokubuka lomsebenzisi, indawo yasendlini ngokuvamile ikhetha u-4.75;
Ubukhulu bebhodi leyunithi yi-64 * 16, okuyibhodi leyunithi elisetshenziswa kakhulu, okulula ukulithenga futhi intengo ishibhile;
1/16 shanela, indlela yokulawula yebhodi leyunithi;
Ukukhanya kwangaphakathi kubhekisela ekukhanyeni kwesibani esikhipha ukukhanya kwe-LED, futhi ukukhanya kwangaphakathi kulungele indawo edinga ukukhanyiswa ngamalambu e-fluorescent phakathi nosuku;
Umbala, umbala owodwa uvame ukusetshenziswa kakhulu, futhi intengo ishibhile, imibala emibili ngokuvamile ibhekisela kokubomvu nokuluhlaza, futhi intengo izoba phezulu kancane;
Ake sithi ufuna ukwenza isikrini esingu-128*16, vele uxhume amabhodi amayunithi amabili ochungechungeni;
2. Amandla
Ngokuvamile, ukunikezwa kwamandla okushintshayo kusetshenziswa, okokufaka okungu-220v, ukuphuma kwe-5v DC, kodwa kufanele kuqashelwe lapha ukuthi ngenxa yokuthi isibonisi esiholayo siyidivayisi ye-elekthronikhi eyinkimbinkimbi, kuyadingeka ukusebenzisa ukunikezwa kwamandla okushintsha esikhundleni se-transformer.Ngendlu eyodwa ebomvu engu-64*16 Uma ibhodi leyunithi likhanya ngokugcwele, lamanje lingu-2a;kungacatshangwa ukuthi okwamanje kwesikrini se-128 * 16 semibala emibili singu-8a esimweni esikhanyayo ngokugcwele, futhi ukunikezwa kwamandla okushintshwa kwe-5v10a kufanele kukhethwe;
3. Ikhadi lokulawula
Sincoma ukusebenzisa ikhadi lokulawula isikrini somugqa oshibhile, elingalawula isikrini esinemibala emibili engu-256*16-dot ngeskena esingu-1/16, futhi singahlanganisa isikrini se-LED ngenzuzo yezindleko eziphezulu.Ikhadi lokulawula liyikhadi elingavumelanisi, okusho ukuthi, Ikhadi lingagcina ulwazi ngemva kokucisha amandla, futhi lingabonisa ulwazi olugcinwe kulo ngaphandle kokuxhuma kukhompyutha.Lapho uthenga ibhodi leyunithi, udinga ukubonana namapharamitha.Ibhodi leyunithi elisebenza ngokugcwele linesixhumi esibonakalayo esingu-08, ibanga lephoyinti elingu-4.75mm, ububanzi bamaphuzu angama-64 namaphuzu ayi-16 ukuphakama., 1/16 scan ukukhanya kwangaphakathi, imibala emibili ebomvu/ebomvu kanye nohlaza;08 esibonakalayo 7.62mm iphuzu ibanga 64 amaphuzu ububanzi * 16 amaphuzu ukuphakama, 1/16 scan ukukhanya kwangaphakathi, imibala emibili ebomvu/obomvu kanye oluhlaza olulodwa;Isixhumi esibonakalayo esingu-08 Ibanga lamaphoyinti angu-7.62 Amaphoyinti angu-64 Ububanzi*amaphoyinti angu-16 ubude, ukukhanya kwangaphandle okungu-1/16 okuyingxenye, okubomvu/obomvu okukodwa kanye nombala emibili oluhlaza;
4. Mayelana ne-interface ye-16PIN08
Ngenxa yokuthi kunabakhiqizi abaningi bamayunithi amabhodi namakhadi okulawula, kunezitayela eziningi zokusebenzisana zebhodi leyunithi.Lapho uhlanganisa isikrini se-LED, kuyadingeka ukuqinisekisa ukuhambisana kwesixhumi esibonakalayo ukuze kube lula umhlangano.Lapha sethula izixhumi ezibonakalayo ze-LED ezivame ukusetshenziswa: Inombolo yomkhakha oholayo: isixhumi esibonakalayo se-16PIN08, ukulandelana kwesixhumi esibonakalayo kungokulandelayo: 2ABCDG1G2STBCLK16
1NNNENR1R2NN15
I-ABCD iyisiginali yokukhetha umugqa, i-STB isignali ye-latch, i-CLK isignali yewashi, i-R1, i-R2, i-G1, i-G2 yidatha yesibonisi, i-EN iwumsebenzi wokubonisa, futhi uN iphansi.Qinisekisa ukuthi ukuxhumana phakathi kwebhodi leyunithi nekhadi lokulawula kuyafana futhi kungaxhunywa ngokuqondile Uma kungahambisani, udinga ukwenza umugqa wokuguqula uwedwa ukuze uguqule ukuhleleka kwemigqa;
5. Umugqa wokuxhuma
Ikakhulukazi ihlukaniswe ngomugqa wedatha, ulayini wokudlulisa, ulayini wamandla, umugqa wedatha usetshenziswa ikakhulukazi ukuxhuma ikhadi lokulawula kanye nebhodi leyunithi ye-LED, umugqa wokudlulisela usetshenziselwa ukuxhuma ikhadi lokulawula nekhompyutha, ulayini wamandla usetshenziswa ukuxhuma. ukunikezwa kwamandla kanye nekhadi lokulawula ukunikezwa kwamandla kagesi kanye nebhodi leyunithi eliholwa, umgogodla wethusi womugqa wamandla oxhuma ibhodi leyunithi akufanele ube ngaphansi kuka-1mm ububanzi;
Okungenhla izingxenye zesakhiwo sesibonisi se-LED esinombala ogcwele.Kafushane, kukhona ikakhulukazi amabhodi amayunithi, izinsiza zamandla, amakhadi okulawula, imigqa yokuxhuma, njll. Ngithemba ukuthi lesi sihloko singaba usizo kuwe.Uma ufuna ukwazi okwengeziwe mayelana nesakhiwo solwazi lwesibonisi se-LED, wamukelekile ukuthi uqhubeke nokunaka.
