Ese OLED ni nziza ku maso yawe?

Uko igihe cyo kureba amashusho gikomeje kwiyongera ku isi, impungenge ku ngaruka z'ikoranabuhanga ryo kwerekana amashusho ku buzima bw'amaso zariyongereye. Mu mpaka zabayeho, hari ikibazo kimwe kigaragara: Ese koko ikoranabuhanga rya OLED (Organic Light-Emitting Diode) ni ryiza ku maso yawe ugereranyije na ecran za LCD zisanzwe?'reba siyansi, ibyiza, n'ibiranga ecran za OLED.

Ecran za OLED zizwiho amabara meza, umukara wijimye, n'ingufu zikoreshwa neza. Bitandukanye na LCD, zikoresha urumuri rw'inyuma, buri pixel iri muri panel ya OLED itanga urumuri rwayo. Iyi miterere idasanzwe itanga ibyiza bibiri bishobora gutuma amaso amererwa neza:

Ibyuka bisohora urumuri rw'ubururu bwo hasi

Ubushakashatsi bwerekana ko kumara igihe kirekire ureba **urumuri rw'ubururu**—cyane cyane muri 400–Intera y'uburebure bw'umurambararo wa 450 nm—bishobora kubangamira ibihe byo gusinzira no kugira uruhare mu gutuma amaso arushaho kugorana. Ecran za OLED zitanga urumuri rw'ubururu ruto ugereranyije na LCD zisanzwe, cyane cyane iyo zigaragaza ibintu byijimye. Nk'uko raporo yo mu 2021 yakozwe na *Harvard Health Publishing* ibigaragaza, OLED'Ubushobozi bwo gukata pixels ku giti cyazo (aho gukoresha itara ry’inyuma risanzwe) bugabanya urumuri rw’ubururu rugera kuri 30% muri rusange mu buryo bwijimye.

Imikorere Idafite Ihindagurika

Ecran nyinshi za LCD zikoresha PWM (Pulse Width Modulation) kugira ngo zihindure urumuri, ruzunguruka vuba cyane rukaza kandi rugazimya urumuri rw'inyuma. Uku kuzima, akenshi kutagaragara, byagaragaye ko bitera kuribwa umutwe no kunanirwa amaso ku bantu bafite ubumuga bwo kubabara. Ecran za OLED, ariko, zigenzura urumuri zihindura urumuri rwa pixel mu buryo butaziguye, zikuraho kuzima mu bihe byinshi.

Nubwo OLED zifite icyizere, ingaruka zazo ku buzima bw'amaso zishingira ku mikoreshereze yazo n'ishyirwa mu bikorwa ry'ikoranabuhanga:

PWM muri Amwe mu ma OLED. Igitangaje ni uko hari ecran zimwe na zimwe za OLED (urugero, telefoni zigendanwa zihendutse) zikoresha PWM mu gushyiraho imiterere y'urumuri ruto kugira ngo zigabanye ingufu. Ibi bishobora kongera guteza ibibazo byo kuzima.

Umucyo mwinshi cyane:Ecran za OLED zishyizwe ku mucyo ntarengwa mu mwijima zishobora gutera urumuri, bikabangamira inyungu zazo z'urumuri rw'ubururu.

Ingaruka zo Gutwika:Ibintu bitajegajega (urugero, imirongo yo kuzenguruka) kuri OLED bishobora kwangiza pixels uko igihe kigenda gihita, bigatuma abakoresha bongera urumuri—bishobora kongera ububabare bw'amaso.

Ibitekerezo by'impuguke

Dr. Lisa Carter, inzobere mu by'amaso muri Vision Health Institute, asobanura agira ati:

"OLED ni intambwe ishimishije mu gutuma amaso amererwa neza, cyane cyane ko urumuri rwazo rw'ubururu rugabanuka kandi ntizibengerane. Ariko, abakoresha bagomba gukurikiza itegeko rya 20-20-20: buri minota 20, reba ikintu kiri kure ya metero 20 mu masegonda 20. Nta ikoranabuhanga rya ecran rishobora gusimbura ingeso nziza."

Hagati aho, abasesenguzi b'ikoranabuhanga bagaragaje iterambere mu buryo bwa OLED bwo kwita ku maso:Samsung's "Ingufu Ihumuriza Amaso"ihindura urumuri rw'ubururu mu buryo bwikora bitewe n'igihe cy'umunsi.LG's "Ishusho y'Ihumure"ihuza urumuri rw'ubururu ruto n'amabara arwanya ubwiza bw'urumuri.

Ecran za OLED, zifite itandukaniro rikomeye n'urumuri rw'ubururu ruto, zitanga inyungu igaragara yo koroherwa n'amaso kurusha LCD zisanzwe.—mu gihe bikoreshejwe neza. Ariko, ibintu nk'imiterere y'urumuri, imikorere idahinduka, hamwe n'imikorere ihamye biracyari ingenzi.
