Nibihe bintu nyamukuru bigize ecran yerekanwe?Hano hari ibicuruzwa byinshi byerekana LED kumasoko, kandi igiciro cyubwoko bumwe bwa LED yerekana kiracyatandukanye cyane.Igice kinini cyimpamvu kiri mubigize.Ubwiza nigiciro cyibice bigize imiterere bizagira ingaruka kubiciro byanyuma byerekana LED.Dukurikire uyumunsi Reka turebe ibice bigize icyerekezo cyerekanwe:
1. Ikibaho
Ikibaho cyibice nimwe mubice byingenzi bigize icyerekezo cyerekanwe.Ubwiza bwibibaho bizagira ingaruka ku buryo bugaragara bwo kwerekana ibyerekanwe.Ikibaho cyibice bigizwe na module iyobowe, chip ya shoferi hamwe ninama yumuzunguruko wa pcb.Module iyobowe mubyukuri igizwe nibintu byinshi LED itanga urumuri rukubiyemo resin cyangwa plastike;
Chip ya shoferi ahanini ni 74HC59574HC245 / 24474HC1384953.
Ibisanzwe bikoreshwa muburyo bwihariye kubisobanuro byimbere mu nzu ni:
Parameter D = 3.75;Akadomo k'akadomo 4.75mm, ubugari bw'akadomo * Uburebure bw'akadomo 16, 1/16 guhanagura umucyo wo mu nzu, umutuku umwe / umutuku n'icyatsi kibisi amabara abiri;
Ibisobanuro
D igereranya diameter ya luminous, yerekeza kuri diameter ya point ya luminous D = 3,75mm;
Intera itanga urumuri ni 4,75mm, ukurikije intera yo kureba uyikoresha, inzu yimbere muri rusange ihitamo 4.75;
Ingano yubuyobozi bwibice ni 64 * 16, ikaba ikoreshwa cyane mubuyobozi bwibice, byoroshye kugura kandi igiciro kirihendutse;
1/16 gusiba, uburyo bwo kugenzura ikibaho cyibice;
Umucyo wo mu nzu bivuga urumuri rw'itara rya LED ritanga urumuri, kandi urumuri rwo mu nzu rukwiranye n'ibidukikije bigomba kumurikirwa n'amatara ya fluorescent ku manywa;
Ibara, ibara rimwe rikoreshwa cyane, kandi igiciro kirahendutse, amabara abiri muri rusange yerekeza kumutuku n'icyatsi, kandi igiciro kizaba kiri hejuru gato;
Dufate ko ushaka gukora ecran ya 128 * 16, huza gusa imbaho zibiri zikurikirana;
2. Imbaraga
Mubisanzwe, guhinduranya amashanyarazi birakoreshwa, 220v yinjiza, 5v DC isohoka, ariko twakagombye kumenya ko kuberako icyerekezo kiyobowe nigikoresho cya elegitoroniki gihanitse, ni ngombwa gukoresha amashanyarazi aho gukoresha transformateur.Ku nzu imwe itukura mu nzu 64 * 16 Iyo ikibaho cyumucyo cyuzuye, ikigezweho ni 2a;birashobora kwemezwa ko ikigezweho cya 128 * 16 ya ecran y'amabara abiri ni 8a muburyo bwuzuye, kandi hagomba gutoranywa amashanyarazi ya 5v10a;
3. Ikarita yo kugenzura
Turasaba ko dukoresha ikarita ihendutse ya karita yo kugenzura ikarita, ishobora kugenzura 256 * 16-akadomo kerekana ibara ryamabara abiri hamwe na 1/16 scan, kandi irashobora guteranya ecran ya LED hamwe nibyiza byo hejuru.Ikarita yo kugenzura ni ikarita idahwitse, ni ukuvuga, Ikarita irashobora kubika amakuru nyuma yo kuzimya, kandi irashobora kwerekana amakuru yabitswemo idahuza na mudasobwa.Mugihe uguze ikibaho, ugomba kubaza ibipimo.Ikibaho cyuzuye cyuzuye gifite intera 08, intera ya 4,75mm, ubugari bwa 64 na 16 hejuru., 1/16 gusikana imbere mu nzu, umutuku umwe / umutuku n'icyatsi kibisi amabara abiri;08 Imigaragarire 7.62mm intera intera 64 ubugari * amanota 16 hejuru, 1/16 gusikana imbere mu nzu, umutuku umwe / umutuku nicyatsi kibisi amabara abiri;Imigaragarire 08 amanota 7,62 intera 64 Ubugari * Uburebure bwamanota 16, 1/16 igice-cyohanagura igice cyo hanze hanze, umutuku umwe / umutuku nicyatsi kibisi-amabara abiri;
4. Hafi ya 16PIN08
Kuberako hari benshi bakora ibibaho byamakarita hamwe namakarita yo kugenzura, hariho uburyo bwinshi bwimiterere yuburyo bwibibaho.Mugihe cyo guteranya ecran ya LED, birakenewe kwemeza guhuza intera kugirango byorohereze inteko.Hano tumenyekanisha ibisanzwe LED ikoreshwa: iyobowe ninganda nimero: 16PIN08 Imigaragarire, urutonde rwimikorere nuburyo bukurikira: 2ABCDG1G2STBCLK16
1NNNENR1R2NN15
ABCD ni ikimenyetso cyo gutoranya umurongo, STB ni ikimenyetso cyerekana, CLK ni ikimenyetso cyamasaha, R1, R2, G1, G2 namakuru yerekana, EN nigikorwa cyo kwerekana, na N nubutaka.Menya neza ko intera iri hagati yikibaho nigice cyikarita igenzura ari imwe kandi ishobora guhuzwa neza Niba bidahuye, ugomba gukora umurongo uhindura wenyine wenyine kugirango uhindure gahunda yumurongo;
5. Guhuza umurongo
Ahanini igabanijwemo umurongo wamakuru, umurongo wohereza, umurongo wamashanyarazi, umurongo wamakuru ukoreshwa cyane cyane muguhuza ikarita yo kugenzura hamwe nubuyobozi bwa LED, umurongo wohereza ukoreshwa muguhuza ikarita yo kugenzura na mudasobwa, umurongo w'amashanyarazi ukoreshwa muguhuza gutanga amashanyarazi hamwe namakarita yo kugenzura amashanyarazi hamwe nubuyobozi buyoboye, intandaro yumuringa wumurongo wamashanyarazi uhuza ikibaho cyibice ntigomba kuba munsi ya 1mm ya diameter;
Ibyavuzwe haruguru nibigize imiterere yuburyo bwuzuye-LED yerekana.Muncamake, hano haribibaho byibice, ibikoresho byamashanyarazi, amakarita yo kugenzura, imirongo ihuza, nibindi nizere ko iyi ngingo ishobora kugufasha.Niba ushaka kumenya byinshi kubyerekeye imiterere ya LED yerekana ubumenyi, urahawe ikaze kugirango ukomeze kwitondera.
