Ni ukubera iki Hejuru LED Yerekana Mugaragaza ikeneye Calibrasi?

Kugirango ugere kumurongo mwiza wo kwerekana, ubuziranenge bwa LED bwerekana ecran muri rusange bigomba guhindurwa kugirango bimurikwe kandi bibe amabara, kugirango umucyo nibara bihoraho bya ecran ya LED nyuma yo kumurika bishobora kugera kubyiza.None ni ukubera iki ecran ya LED yerekana ubuziranenge ikeneye guhindurwa, kandi ikenera gute?

Igice.1

Ubwa mbere, birakenewe gusobanukirwa ibintu byingenzi biranga amaso yumuntu kumva umucyo.Umucyo nyawo ubonwa nijisho ryumuntu ntaho uhuriye numucyo utangwa na anLED yerekana, ahubwo ni umubano utari umurongo.

Kurugero, iyo ijisho ryumuntu rireba LED yerekana ecran ifite umucyo nyawo wa 1000nit, tugabanya umucyo kuri 500nit, bigatuma 50% igabanuka kumurika.Nyamara, urumuri rugaragara rwamaso yumuntu ntirugabanuka neza kugeza kuri 50%, ahubwo ni 73% gusa.

Umurongo utari umurongo hagati yumucyo ugaragara wijisho ryumuntu nubucyo nyabwo bwa ecran ya LED yerekana bita gamma curve (nkuko bigaragara ku gishushanyo 1).Uhereye kumirongo ya gamma, birashobora kugaragara ko imyumvire yumucyo ihinduka nijisho ryumuntu isa naho idafite ishingiro, kandi amplitude nyayo yumucyo uhinduka kumurongo wa LED ntabwo ihuye.

Ibikurikira, reka twige ibiranga imyumvire y'amabara ihinduka mumaso yumuntu.Igishushanyo cya 2 ni CIE ya chromaticity chart, aho amabara ashobora kugaragazwa namabara ya cooride cyangwa uburebure bwumucyo.Kurugero, uburebure bwumurongo wa LED isanzwe yerekana ni 620 nanometero kuri LED itukura, 525 nanometero kuri LED icyatsi kibisi, na nanometero 470 kuri LED yubururu.

Muri rusange, mumwanya umwe wamabara, ijisho ryumuntu ryihanganira itandukaniro ryamabara ni Δ Euv = 3, bizwi kandi nkibiboneka bigaragara ibara ritandukanye.Iyo itandukaniro ryamabara hagati ya LED riri munsi yagaciro, bifatwa ko itandukaniro ridafite akamaro.Iyo Δ Euv> 6, byerekana ko ijisho ryumuntu ryumva itandukaniro rikomeye ryamabara hagati yamabara abiri.

Cyangwa muri rusange bizera ko iyo itandukaniro ryumuraba rirenze nanometero 2-3, ijisho ryumuntu rishobora kumva itandukaniro ryamabara, ariko ibyiyumvo byijisho ryumuntu kumabara atandukanye biracyatandukanye, kandi itandukaniro ryumuraba wijisho ryumuntu rishobora kubona. kuko amabara atandukanye ntabwo yashizweho.

Urebye uburyo butandukanye bwo kumurika no kurangi ukoresheje ijisho ryumuntu, ecran ya LED igomba kugenzura itandukaniro ryumucyo namabara murwego ijisho ryumuntu ridashobora kubona, kugirango ijisho ryumuntu rishobore kumva neza guhuzagurika no kumurika kandi ibara iyo ureba LED yerekana ecran.Umucyo hamwe nibara ryibikoresho bya LED bipakira cyangwa ibyuma bya LED bikoreshwa muri ecran ya LED bigira ingaruka zikomeye kumyerekano.

Mugihe ukora LED yerekana ecran, ibikoresho byo gupakira LED bifite umucyo nuburebure bwumurongo murwego runaka birashobora gutoranywa.Kurugero, ibikoresho bya LED bifite urumuri ruri hagati ya 10% -20% nuburebure bwumurambararo muri nanometero 3 birashobora guhitamo kubyara umusaruro.

Guhitamo ibikoresho bya LED hamwe nurwego ruto rwurumuri nuburebure bwumurongo birashobora ahanini kwemeza guhuza ecran yerekana no kugera kubisubizo byiza.

Nyamara, urumuri rwinshi nuburebure bwumurongo wibikoresho bya LED bipakira bisanzwe bikoreshwa muri ecran ya LED byerekana bishobora kuba binini kuruta urwego rwiza twavuze haruguru, ibyo bikaba bishobora kuvamo itandukaniro ryumucyo namabara yibikoresho bya LED bitanga urumuri bigaragara mumaso yumuntu. .

Ikindi kintu ni ugupakira COB, nubwo umucyo winjira hamwe nuburebure bwumurabyo wa LED itanga urumuri rushobora kugenzurwa murwego rwiza, birashobora kandi gutuma umucyo hamwe nibara bidahuye.

Kugirango ukemure uku kudahuza muri ecran ya LED no kunoza ireme ryerekana, tekinoroji yo gukosora ingingo irashobora gukoreshwa.

Ingingo ku gukosora ingingo

Ingingo ku ngingo ikosora ni inzira yo gukusanya umucyo na chromaticity data kuri buri sub pigiseli kuri anLED yerekana, gutanga coefficient zo gukosora kuri buri shingiro ryamabara sub pigiseli, no kubagaburira gusubira muri sisitemu yo kugenzura ecran yerekana.Igenzura rya sisitemu rikoresha coefficient zo gukosora kugirango itware itandukaniro rya buri shingiro ryamabara sub pigiseli, bityo bitezimbere uburinganire bwumucyo na chromaticité hamwe nubudahemuka bwamabara yerekana ecran.

Incamake

Imyumvire yumucyo uhindagurika ya chip ya LED nijisho ryumuntu yerekana isano itari umurongo hamwe nimpinduka nyazo zumucyo za LED.Uyu mugongo witwa gamma curve.Ibyiyumvo byijisho ryumuntu kuburebure butandukanye bwamabara atandukanye, kandi ecran ya LED ifite ingaruka nziza zo kwerekana.Umucyo n'amabara atandukanye ya ecran yerekana bigomba kugenzurwa murwego ijisho ryumuntu ridashobora kumenya, kugirango ecran ya LED yerekana kwerekana neza.

Umucyo nuburebure bwibikoresho bipakiye LED cyangwa COB ipakiye LED itanga urumuri rufite intera runaka.Kugirango hamenyekane neza icyerekezo cya LED cyerekana, tekinoroji ku ngingo yo gukosora irashobora gukoreshwa kugirango ugere ku mucyo uhoraho hamwe na chromaticitike yo mu rwego rwo hejuru ya LED yerekana kandi tunoze ubuziranenge bwerekana.
