Ibya kera n'iby'ubu: Amateka y'ikoranabuhanga rya LED ecran

Kubera iterambere ryose riri gutezwa imbere mu ikoranabuhanga ryo kwerekana amashusho, bisa nkaho bidashoboka kwemera ko ubumenyi bwakoreshejwe mu gukora no guteza imbere iri koranabuhanga bufite imyaka irenga ijana. Mu by’ukuri, intambwe za mbere mu rwego rw’ikoranabuhanga ryo kwerekana amashusho zatangiye mu 1897 ubwo Karl Ferdinand Braun, umuhanga mu bya fiziki akaba n’umuvumbuzi, yubakaga Cathode Ray Tube ya mbere. Iyi mashini ntoya yagombaga kwemerera kubaka televiziyo za mbere bityo igatuma habaho inganda zateye imbere cyane kuva yashingwa.

Iterambere rya kabiri rigaragara mu ikoranabuhanga ryo kwerekana ryatangiye nyuma y'imyaka icumi, mu 1907 ubwo havumburwaga Electroluminescence. Iki kintu karemano cyatanze iterambere rya mbere mu ikoranabuhanga rya LED. Mu 1952 habayeho iterambere rya ecran ya mbere yari ipfutse, kandi yashyizwe mu byumba bike byo muri Leta Zunze Ubumwe za Amerika. Iryo koranabuhanga ntiryari kuboneka ku baguzi mu gihe cy'imyaka mirongo itanu.

Intambwe ikomeye yakurikiyeho mu mateka ya ecran ni uguhanga itara rya mbere rya LED mu 1961. Robert Biard na Gary Pittman batanze patenti y'urumuri rwa mbere rwa LED rwa infrared rwa Texas Instruments. Umwaka wakurikiyeho Nick Holonyack yakoze urumuri rwa mbere rwa LED rugaragara. Nyuma y'imyaka ibiri, mu 1964, ikoranabuhanga rya ecran ryateye indi ntambwe ikomeye hamwe n'ivumburwa rya LCD na plasma screens ryakozwe n'umuhanga w'umunyamerika James Fergason.

Nubwo ikoranabuhanga ryo kwerekana telefoni zigendanwa ari rishya, ecran ya mbere muri izi yavumbuwe mu 1965 kandi ni yo ya mbere yakoreshejwe mu kugenzura indege. HDTV nayo yatangiye mu Buyapani mu myaka ya 1960 na 1970, nubwo HDTV zitageze muri Leta Zunze Ubumwe za Amerika kugeza mu 1998. Nubwo abantu binjiraga muri ecran zo mu myaka ya za 90, OLED zavumbuwe na Kodak bityo babona ecran ya mbere yuzuye amabara ya plasma.

Igitangaje ni uko inganda zo kwerekana amashusho zagutse vuba kandi zizakomeza kubikora. Ecran z'ingano zitandukanye, imiterere n'ikoranabuhanga bizakomeza guterwa imbere mu bikorwa bitandukanye. Kubera iyo mpamvu, akamaro ko gupima ecran neza kazatera imbere cyane. Konica Minolta ifite uburyo bwinshi bwo gupima amashusho kugira ngo ihuze n'impinduka mu nganda zo kwerekana amashusho.
