Iyo ecran ya LED ikoreshwa mubyumba bigenzura, sitidiyo ya TV nahandi hantu, birashobora rimwe na rimwe gutera moire kubangamira ifoto ya kamera.Uru rupapuro rugaragaza ibitera nigisubizo cya moire, kandi rwibanda ku buryo bwo guhitamo ecran ya LED kugirango igabanye cyangwa ikureho moire.
1.Ni gute moire yabayeho?
2.Ni gute ushobora gukuraho cyangwa kugabanya moire?
3.Ni gute wahindura imiterere ya gride ya kamera CCD na LED yerekana?
4.Ni gute ushobora guhindura agaciro kagereranijwe kamera CCD na LED yerekana imiterere ya gride?
5.Hariho uburyo bwo guhindura agace kirabura katarabagirana ahantu hakeye kuri ecran ya LED?
Mugihe ufata amashusho kuri ecran ya elegitoroniki yerekana ikora, imirongo idasanzwe hamwe nimpanuka zidasanzwe bizagaragara.Izi mpanuka zitwa moire fringes cyangwa moire ingaruka.Ingaruka ya Moire ni imyumvire igaragara.Iyo itsinda ryimirongo cyangwa ingingo bibonetse hejuru yandi matsinda yimirongo cyangwa ingingo, iyi mirongo cyangwa ingingo biratandukanye mubunini ugereranije, inguni cyangwa intera.
Ingaruka nyamukuru yingaruka za Moore ni tereviziyo na kamera.Niba itara riri muri pigiseli ya LED yerekana ecran ya ecran itaringanijwe, ubwiza bwibishusho kuri ecran ya LED yerekana ibyerekanwa bizagira ingaruka kandi urumuri ruzaterwa mugihe ecran yerekanwe neza.Ibi bitera ikibazo gikomeye kubyara sitidiyo za TV nibindi bikoresho bya videwo.
（1） Moire yabayeho ite?
Moire:
Iyo ibishushanyo bibiri bifite umwanya munini uhuzagurika, ubundi buryo bushya busanzwe bukorwa, ubusanzwe bwitwa moire (nkuko bigaragara ku gishushanyo 2).
Mugaragaza LED gakondo ya ecran itunganijwe na pigiseli yigenga yigenga, kandi haribintu bigaragara bitagaragara kumurika hagati ya pigiseli.Muri icyo gihe, ikintu cyunvikana cya kamera ya digitale nayo ifite ahantu hagaragara intege nke zumucyo mugihe zumva urumuri.Iyo ibyerekanwe bya digitale hamwe nifoto ya digitale ibaho icyarimwe, imiterere ya moire iravuka.
Kubera ko intego ya CCD (sensor sensor) igaragara hejuru yubuso (fotosensitif yubuso) ya kamera isa nigishushanyo kiri hagati yishusho ya 2, mugihe ecran gakondo ya LED yerekana isa nishusho kuruhande rwibumoso rwishusho 2. Irahimbwe y'urumuri ruto rusohora imiyoboro itunganijwe muburyo bumwe.Mugaragaza byose ecran ifite ahantu hanini hatari urumuri, ikora gride nkishusho.Guteranya byombi bigira ishusho ya moire isa kuruhande rwiburyo bwishusho 2.
（2） Nigute ushobora gukuraho cyangwa kugabanya moire?
Kuva LED yerekana imiyoboro ya interineti ikorana na kamera ya CCD ya gride kugirango ikore imiterere ya moire, ihindure agaciro kagereranijwe hamwe nimiterere ya gride ya kamera ya CCD ya gride hamwe na LED yerekana imiyoboro ya LED irashobora gukuraho cyangwa kugabanya imiterere ya moire.
（3） Nigute ushobora guhindura imiterere ya gride ya kamera CCD na LED yerekana?
Muburyo bwo gufata amashusho, nta pigiseli ihari isanzwe ikwirakwizwa, kubwibyo rero nta mwanya uhoraho uhari kandi nta moire.
Kubwibyo, moire phenomenon nikibazo cyatewe na digitale ya kamera ya TV.Kurandura moire, imiterere ya LED yerekana ecran ishusho yafashwe mumurongo igomba kuba munsi yumwanya muto wibintu byoroshye.Iyo ibi bisabwa byujujwe, nta mpande zisa nizo za sensor zishobora kugaragara ku ishusho, bityo nta moire izabyara.
Muri kamera zimwe na zimwe za digitale, hashyizweho akayunguruzo gato gashungura kugirango ushungure igice kinini cyumwanya wigice cyishusho kugirango ugabanye moire, ariko ibi bizagabanya ubukana bwishusho.Kamera zimwe za digitale zikoresha umwanya munini wo kumva ibintu.
（4） Nigute ushobora guhindura agaciro kagereranya kamera CCD na LED yerekana imiterere ya gride?
1. Hindura inguni yo gufata kamera.Muguhinduranya kamera no guhindura gato impande zo kurasa za kamera, impanuka ya moire irashobora kuvaho cyangwa kugabanuka.
2. Hindura umwanya wo gufata kamera.Iyo wimuye kamera ibumoso n'iburyo cyangwa hejuru no hepfo, urashobora gukuraho cyangwa kugabanya impanuka ya mole.
3. Hindura icyerekezo cyibanze kuri kamera.Ibyibandwaho hamwe nibisobanuro birambuye bisobanutse neza kubishushanyo birambuye birashobora gutera impanuka.Guhindura buhoro buhoro icyerekezo cyibanze kirashobora guhindura ibisobanuro, bityo bigafasha gukuraho imvururu zonyine.
4. Hindura uburebure bwibanze bwa lens.Ibice bitandukanye cyangwa uburebure buringaniye birashobora gukoreshwa mugukuraho cyangwa kugabanya imishwarara.
LED yerekana ecran itunganijwe na pigiseli yigenga yigenga, kandi hari ibiboneka byirabura bitagaragara hagati ya pigiseli.Shakisha uburyo bwo guhindura agace kirabura kitagira urumuri ahantu hakeye, kandi ugabanye itandukaniro ryumucyo hamwe na pigiseli yigenga yigenga, ishobora kugabanya cyangwa gukuraho moire.
（5） Hariho uburyo bwo guhindura agace kirabura katarabagirana ahantu hakeye kuri LED yerekana?
COB ipakira inzira LED yerekana, biroroshye gukora ibi.Niba dufite amahirwe yo gushyira LED yerekana COB hamwe na LED yerekana SMD, dushobora kubona byoroshye ko: LED yerekana COB itanga urumuri rworoshye nkisoko yumucyo wo hejuru, mugihe LED yerekana SMD bigaragara ko yumva ko ibice bya luminous ni ingingo zigenga.Birashobora kugaragara ku gishushanyo cya 3 ko uburyo bwo gufunga ibicuruzwa bya COB butandukanye cyane nubwa SMD.Uburyo bwo gufunga ibicuruzwa bya COB nubuso rusange busohora urumuri rwa pigiseli nyinshi zisohora urumuri hamwe.Uburyo bwo gufunga uburyo bwo gupakira SMD ni pigiseli imwe ya luminous, ni ingingo yigenga.
MPLED irashobora kuguha LED yerekana uburyo bwo gupakira COB, kandi ibicuruzwa byacu bya ST Pro birashobora gutanga ibisubizo nkibi.LED yerekana ecran yujujwe nuburyo bwo gupakira cob ifite intera ntoya, isobanutse kandi yoroheje yerekana ishusho.Chip itanga urumuri ipakirwa ku kibaho cya PCB, kandi ubushyuhe bukwirakwizwa mu kibaho.Agaciro ko kurwanya ubushyuhe ni nto, kandi gukwirakwiza ubushyuhe birakomeye.Itara ryo hejuru risohora urumuri.Kugaragara neza.
Umwanzuro: Nigute ushobora gukuraho cyangwa kugabanya moire kuri LED yerekana?
1. Hindura kamera yo gufotora, umwanya, gushiraho icyerekezo hamwe nuburebure bwa lens.
2. Koresha kamera ya firime gakondo, kamera ya digitale ifite sensor yumwanya muremure, cyangwa kamera ya digitale ifite akayunguruzo gato.
3. LED yerekana ecran muburyo bwo gupakira COB yatoranijwe.
