Kuyobora Ibyingenzi

LED yerekana ni ikibaho cyerekana, kigizwe na mato mato mato mato ya LED, akoreshwa mu kwerekana inyandiko, amashusho, amashusho, ibimenyetso bya videwo nibindi bikoresho bitandukanye byamakuru.

Ikoreshwa cyane cyane kwamamaza hanze, kwamamaza, gukina, gukina inyuma nibindi bikorwa. Bikunze gushyirwa mubice byubucuruzi, impande zinyubako, umuhanda wumuhanda, ibibuga rusange, ibyumba byimbere, ibyumba byinama, sitidiyo, inzu y'ibirori, ibigo byategekaga nahandi, bigira uruhare mukwerekana.

Ⅰ. ihame ryakazi rya LED kwerekana

Ihame ryibanze ryakazi rya LED yerekana ni dinamike yo gusikana. Gusikana Dynamic bigabanijwemo umurongo wo gusikana hamwe ninkingi yo gusikana inzira ebyiri, uburyo bukoreshwa cyane ni umurongo wo gusikana. Gusikana umurongo bigabanijwemo imirongo 8 yo gusikana no 16 kumurongo.

Muburyo bwo gusikana kumurongo wibikorwa, buri gice cya LED dot matrix igice gifite umurongo wuruziga rwumuzingi, umuzenguruko winkingi ugomba kuba ufite latch cyangwa shift rejisitiri, ikoreshwa mugufunga ibirimo kugirango byerekanwe mumagambo yuburyo bwamakuru. Muburyo bwo gusikana kumurongo wibikorwa, umurongo umwe wa LED dot-matrix igice kimwe cyizina ryumurongo ugenzura pin ihujwe kuburinganire kumurongo, imirongo 8 yose, hanyuma amaherezo ihuza umurongo utwara umurongo; umurongo wumurongo wumurongo ugomba kuba ufite latch cyangwa shift rejisitiri, ikoreshwa mugufunga umurongo wo gusikana.

LED yerekana inkingi yumurongo wumurongo wumurongo wumurongo ukoreshwa mubisanzwe bikoreshwa mugucunga microcontroller, bikunze gukoreshwa microcontroller ni MCS51. LED yerekana ibirimo muri rusange ibitswe muburyo bwijambo muburyo bwa microcontroller yibuka ryamakuru yo hanze, ijambo ryuburyo ni 8-biti nimero.

Ⅱ. ubumenyi bwibanze bwa Led kwerekana

1, LED ni iki?

LED ni impfunyapfunyo ya diode yerekana urumuri (URUMURI RWA EMITTING DIODE), hamwe na diode itanga urumuri rugizwe nibikoresho byerekana. Inganda zerekana ko LED yerekeza LED ishobora kohereza uburebure bugaragara.

2, LED yerekana iki?

Binyuze muburyo bumwe bwo kugenzura, ibikoresho bya LED bigizwe na ecran ya ecran.

3, moderi yerekana LED ni iki?

Hano hari imirongo nuburyo bwo kwishyiriraho kugirango tumenye, hamwe nibikorwa byo kwerekana, birashobora kugerwaho binyuze mumikorere yoroshye yo guteranya ibikorwa byibanze.

4, Moderi yerekana LED ni iki?

Igizwe numubare werekana pigiseli, muburyo bwigenga, irashobora gukora agace gato ka LED yerekana. Ibisanzwe 8 * 8, 8 * 7, nibindi ..

5. Ikibanza cya pigiseli ni iki?

Intera hagati hagati ya pigiseli ebyiri zegeranye, ntoya ikibuga, kigufi intera igaragara. Inganda mubisanzwe mu magambo ahinnye P kugirango yerekane intera iri hagati.

6, Ubucucike bwa pigiseli ni iki?

Bizwi kandi nkubucucike bwadomo, mubisanzwe bivuga umubare wa pigiseli kuri metero kare kwerekanwa.

7, Umucyo urumuri ni iki?

LED yerekana igice cyatanzwe nubushyuhe bwurumuri, igice ni CD / metero kare, shyira gusa ni metero kare yerekana itangwa nuburemere bwurumuri;

8, ni ubuhe mucyo wa LED yerekana?

LED yerekana ububengerane bivuga imikorere isanzwe yerekana, igice cyerekana igice cyuburemere bwumucyo, igice ni cd / m2 (nukuvuga, ni bangahe cd yububasha bwa luminous kuri metero kare yubuso bwerekanwe.

11, Urwego rw'imvi ni iki?

Urwego rwimyenda ya LED yerekana ni ikimenyetso cyerekana ishusho yerekana. Urwego rwimyenda ya ecran ya videwo muri rusange igabanijwemo urwego 64, urwego 128, urwego 256, urwego 512, urwego 1024, urwego 2048, urwego 4096 nibindi. Urwego rwohejuru rwimyenda, urwego rusobanutse neza, urwego rusange rwimyenda ya 256 cyangwa irenga, itandukaniro ryibishusho ntabwo rinini cyane.

12, ni ubuhe bwoko bubiri, ibara rya pseudo, ibara ryuzuye?

Binyuze mu mabara atandukanye ya diode itanga urumuri rushobora kuba rugizwe nuburyo butandukanye, amabara abiri agizwe numutuku, icyatsi cyangwa umuhondo-icyatsi kibisi amabara abiri, pseudo-ibara rigizwe numutuku, umuhondo-icyatsi, ubururu amabara atatu atandukanye, yuzuye -amabara agizwe numutuku, icyatsi kibisi, ubururu bwera butatu butandukanye.

13, moire ni iki?

Ni mubikorwa byo kurasa byerekana ibara ryuzuye rya LED, ecran ya LED hazaba hari amazi adasanzwe, aya mazi muri fiziki yitwa "moiré".

14, SMT ni iki, SMD ni iki?

SMT ni tekinoroji yubatswe hejuru (SURFACE MOUNTED tekinoroji ya make), kuri ubu ni tekinoroji n'inzira bizwi cyane mu nganda ziteranya ibikoresho bya elegitoroniki; SMD ni igikoresho gishyizwe hejuru (igikoresho gishyizwe hejuru mugihe gito).

LED yerekana ni ubwoko bushya bwamakuru yerekana itangazamakuru, ni igenzura ryumucyo utanga urumuri rwa diode yerekana uburyo bwa ecran ya ecran yerekana, irashobora gukoreshwa mukwerekana inyandiko, ibishushanyo nubundi bwoko bwamakuru ahamye hamwe na animasiyo, videwo nubundi bwoko bwa amakuru yingirakamaro, LED yerekana ibyuma bya elegitoronike yerekana tekinoroji ya tekinoroji, tekinoroji ya mudasobwa, gutunganya amakuru muri imwe, hamwe namabara meza, intera yagutse, urumuri rwinshi, ubuzima burebure, butajegajega kandi bwizewe, nibindi byiza, bikoreshwa cyane mubitangazamakuru byubucuruzi, isoko ryimikorere yumuco, ibibuga by'imikino, gukwirakwiza amakuru, gutangaza amakuru, gucuruza impapuro, nibindi, birashobora guhaza ibikenewe mubidukikije bitandukanye. Ukurikije ibara shingiro ryibara rishobora kugabanywamo ibara rimwe ryerekana no kwerekana amabara yuzuye.
