LED yerekana ibyuma bya elegitoronike bifite pigiseli nziza, uko byagenda kose cyangwa nijoro, izuba cyangwa imvura, LED yerekana irashobora gutuma abayumva babona ibirimo, kugirango abantu babone sisitemu yo kwerekana.
Tekinoroji yo gushaka amashusho
Ihame nyamukuru rya LED yerekana ibyuma bya elegitoronike ni uguhindura ibimenyetso bya digitale mubimenyetso byamashusho hanyuma ukabigaragaza binyuze muri sisitemu yumucyo.Uburyo gakondo nugukoresha ikarita yo gufata amashusho hamwe namakarita ya VGA kugirango ugere kumikorere yo kwerekana.Igikorwa nyamukuru cyikarita yo kugura amashusho nugufata amashusho ya videwo, no kubona aderesi yerekana umurongo wumurongo wumurongo, inshuro yumurima hamwe na pigiseli ya VGA, kandi ukabona ibimenyetso bya digitale cyane cyane wandukuye imbonerahamwe yo kureba amabara.Mubisanzwe, software irashobora gukoreshwa mugihe cyo kwigana cyangwa kwiba ibyuma, ugereranije nubujura bwibikoresho birakorwa neza.Nyamara, uburyo gakondo bufite ikibazo cyo guhuza na VGA, biganisha ku mpande zidahwitse, kutagira ishusho mbi nibindi, hanyuma bikangiza ubwiza bwibishusho byerekana ibikoresho bya elegitoroniki.
Hashingiwe kuri ibi, impuguke mu nganda zateguye ikarita ya videwo yabugenewe JMC-LED, ihame ry’ikarita rishingiye kuri bisi ya PCI ikoresha umuvuduko wa 64-bit ya grafika yihuta kugira ngo iteze imbere imikorere ya VGA na videwo muri imwe, no kugera ku makuru ya videwo n’amakuru ya VGA kuri shiraho ingaruka zidasanzwe, ibibazo byabanje guhuza byakemuwe neza.Icya kabiri, kugura ibyemezo bifata uburyo bwuzuye bwa ecran kugirango harebwe neza neza amashusho ya videwo, igice cyuruhande ntikikiri urujijo, kandi ishusho irashobora gupimwa uko bishakiye kandi ikimurwa kugirango ihuze ibyifuzo bitandukanye byo gukina.Hanyuma, amabara atatu yumutuku, icyatsi nubururu arashobora gutandukana neza kugirango ahuze ibisabwa byukuri bya elegitoronike yerekana.
2. Kwerekana ibara ryukuri
Ihame rya LED yuzuye-amabara yerekana asa na tereviziyo mubijyanye no gukora amashusho.Binyuze muburyo bwiza bwo guhuza amabara atukura, icyatsi nubururu, amabara atandukanye yishusho arashobora kugarurwa no kubyara.Ubuziranenge bwamabara atatu atukura, icyatsi nubururu bizagira ingaruka kumyororokere yibara ryibishusho.Twabibutsa ko kubyara ishusho atari uburyo bwo guhuza amabara atukura, icyatsi nubururu, ariko birasabwa ikintu runaka.
Icyambere, igipimo cyurumuri rwumutuku, icyatsi nubururu bigomba kuba hafi ya 3: 6: 1;Icyakabiri, ugereranije nandi mabara abiri, abantu bafite sensibilité yumutuku mubyerekezo, birakenewe rero gukwirakwiza neza umutuku mumwanya wo kwerekana.Icya gatatu, kubera ko iyerekwa ryabantu risubiza umurongo utari umurongo wurumuri rwurumuri rwumutuku, icyatsi nubururu, birakenewe gukosora urumuri rwasohotse imbere ya TV ukoresheje urumuri rwera nuburemere butandukanye bwurumuri.Icya kane, abantu batandukanye bafite ubushobozi butandukanye bwo gukemura amabara mubihe bitandukanye, birakenewe rero kumenya ibipimo bifatika byerekana imyororokere yamabara, mubisanzwe nkibi bikurikira:
(1) Uburebure bwumutuku, icyatsi nubururu byari 660nm, 525nm na 470nm;
.
(3) Urwego rwimyenda yamabara atatu yibanze ni 256;
(4) Ikosora ridafite umurongo rigomba kwemezwa gutunganya pigiseli LED.
Sisitemu itukura, icyatsi nubururu ikwirakwiza igenzura rishobora kugerwaho na sisitemu yibikoresho cyangwa na software ikinisha.
3. umuzenguruko udasanzwe wukuri
Hariho uburyo bwinshi bwo gutondekanya pigiseli ya none: (1) scan ya scan;(2) DC;(3) imiyoboro ihoraho.Ukurikije ibisabwa bitandukanye bya ecran, uburyo bwo gusikana buratandukanye.Kuri ecran ya lattice yo mu nzu, uburyo bwo gusikana bukoreshwa cyane.Kuri ecran ya pigiseli yo hanze, kugirango tumenye neza kandi neza neza ishusho yayo, uburyo bwo gutwara DC bugomba gukoreshwa kugirango hongerwemo imiyoboro ihoraho kubikoresho byo gusikana.
LED yo hambere yakoreshaga cyane cyane ibimenyetso byerekana ibimenyetso bike hamwe nuburyo bwo guhindura, ubu buryo bufite ingingo nyinshi zagurishijwe, igiciro kinini cyumusaruro, ubwizerwe budahagije hamwe nandi makosa, utunenge twagabanije iterambere rya LED yerekana ibyuma bya elegitoronike mugihe runaka.Kugirango ukemure amakosa yavuzwe haruguru yerekana LED yerekana ibyuma bya elegitoronike, isosiyete yo muri Reta zunzubumwe zamerika yateje imbere porogaramu yihariye ihuriweho, cyangwa ASIC, ishobora kumenya urukurikirane-ruhinduranya hamwe na disiki igezweho muri imwe, umuzenguruko uhuriweho ufite ibintu bikurikira : parallel isohoka ubushobozi bwo gutwara, gutwara ibyiciro bigera kuri 200MA, LED kuriyi shingiro irashobora gutwarwa ako kanya;Kwihangana kwinshi na voltage kwihanganira, intera yagutse, mubisanzwe birashobora kuba hagati ya 5-15V byoroshye;Ibisohoka-bisa nibisohoka bigezweho ni binini, ibyinjira nibisohoka birenze 4MA;Byihuta gutunganya amakuru yihuta, bikwiranye nubu-ibara ryinshi ryamabara LED yerekana imikorere yumushoferi.
4. kugenzura ububengerane bwa tekinoroji ya D / T.
LED yerekana ibyuma bigizwe na pigiseli nyinshi yigenga ukurikije gahunda no guhuza.Ukurikije uburyo bwo gutandukanya pigiseli nizindi, LED yerekana ibyuma bya elegitoronike irashobora kwagura gusa uburyo bwayo bwo kugenzura ibiyobora binyuze mubimenyetso bya digitale.Iyo pigiseli imurikirwa, imiterere yayo yumucyo igenzurwa cyane na mugenzuzi, kandi ikayoborwa yigenga.Iyo videwo igomba kwerekana ibara, bivuze ko umucyo nibara bya buri pigiseli bigomba kugenzurwa neza, kandi igikorwa cyo gusikana gisabwa kurangizwa icyarimwe mugihe cyagenwe.
Bimwe mu bikoresho bya elegitoroniki LED bigizwe na pigiseli ibihumbi mirongo, byongera cyane ubunini mugikorwa cyo kugenzura amabara, bityo ibisabwa byo hejuru bigashyirwa imbere kugirango amakuru yoherezwe.Ntabwo ari ibintu byukuri gushiraho D / A kuri buri pigiseli mubikorwa nyabyo byo kugenzura, birakenewe rero gushakisha gahunda ishobora kugenzura neza sisitemu ya pigiseli igoye.
Iyo usesenguye ihame ryerekezo, usanga impuzandengo yumucyo wa pigiseli ahanini biterwa nigipimo cyayo.Niba igipimo cyo kumurika cyahinduwe neza kuriyi ngingo, kugenzura neza umucyo birashobora kugerwaho.Gushyira mu bikorwa iri hame kuri LED yerekana ibikoresho bisobanura guhindura ibimenyetso bya digitale mubimenyetso byigihe, ni ukuvuga guhinduka hagati ya D / A.
5. Kwubaka amakuru no gukoresha ikoranabuhanga
Kugeza ubu, hari inzira ebyiri zingenzi zo gutunganya amatsinda yo kwibuka.Imwe ni uburyo bwo guhuza pigiseli uburyo, ni ukuvuga, ingingo zose za pigiseli ku ishusho zibitswe mu mubiri umwe wo kwibuka;ubundi nuburyo buke bwindege, ni ukuvuga, ingingo zose za pigiseli ku ishusho zibitswe mumibiri itandukanye.Ingaruka itaziguye yo gukoresha byinshi mububiko ni ukumenya amakuru atandukanye ya pigiseli isoma icyarimwe.Mubintu bibiri byavuzwe haruguru, uburyo bwindege ya bito ifite ibyiza byinshi, nibyiza mugutezimbere ingaruka zerekana ecran ya LED.Binyuze mumasoko yo kongera kubaka kugirango ugere ku ihinduka ryamakuru ya RGB, uburemere bumwe hamwe na pigiseli zitandukanye burahujwe muburyo bushyirwa mububiko bwegeranye.
6. Ikoranabuhanga rya ISP muburyo bwa logic circuit
Imiyoboro gakondo ya LED yerekana igenzura ryakozwe cyane cyane nubusanzwe bwa digitale isanzwe, igenzurwa nubusanzwe bwa sisitemu.Mubuhanga gakondo, nyuma yo gushushanya igice cyumuzunguruko kirangiye, ikibaho cyumuzunguruko gikozwe mbere, kandi ibice bijyanye birashyirwaho kandi ingaruka zirahinduka.Iyo imikorere yumuzunguruko wibikorwa idashobora guhura nibisabwa nyabyo, igomba gusubirwamo kugeza yujuje ingaruka zo gukoresha.Birashobora kugaragara ko uburyo bwa gakondo bwo gushushanya butagira gusa urwego runaka rwibihe byateganijwe, ariko kandi bufite ibizunguruka birebire, bigira ingaruka kumajyambere myiza yibikorwa bitandukanye.Iyo ibice binaniwe, kubungabunga biragoye kandi ikiguzi ni kinini.
Kuri iyi shingiro, tekinoroji ya porogaramu ikoreshwa (ISP) yagaragaye, abayikoresha barashobora kugira umurimo wo guhindura inshuro nyinshi intego zabo zo gushushanya hamwe na sisitemu cyangwa ikibaho cyumuzunguruko nibindi bice, bakamenya inzira ya porogaramu yibikoresho byabashushanyo kuri porogaramu ya software, sisitemu ya sisitemu kuri shingiro rya sisitemu ikorana buhanga ifata isura nshya.Hamwe nogutangiza tekinoroji ya sisitemu ishobora gukoreshwa, ntabwo igishushanyo mbonera cyagabanijwe gusa, ahubwo no gukoresha ibice byaraguwe cyane, kubungabunga imirima nibikorwa byibikoresho byoroshywe.Ikintu cyingenzi kiranga tekinoroji ya sisitemu ni uko idakeneye gusuzuma niba igikoresho cyatoranijwe gifite icyo gihindura mugihe ukoresheje software ya sisitemu yo kwinjiza logique.Mugihe cyo kwinjiza, ibice birashobora gutoranywa uko bishakiye, ndetse nibice bigize ibice bishobora gutoranywa.Nyuma yo kwinjiza birangiye, guhuza n'imihindagurikire y'ikirere birashobora gukorwa.
