Ibihe byashize nubu: Amateka ya LED Yerekana Ikoranabuhanga

Hamwe niterambere ryose ririmo gutezwa imbere mubuhanga bwo kwerekana, bisa nkibidashoboka kwizera ko ubumenyi bwakoreshejwe mugukora no guteza imbere ubwo buhanga bumaze imyaka irenga ijana. Mubyukuri, intambwe yambere mubijyanye no kwerekana ikoranabuhanga ryatangiye mu 1897 igihe Karl Ferdinand Braun, umuhanga mu bya fiziki akaba n'uwahimbye, yubatse Cathode Ray Tube ya mbere. Iyi nto yagombaga kwemerera kubaka tereviziyo ya mbere bityo igashiraho inganda zateye imbere cyane kuva yatangira.

Iterambere rya kabiri rigaragara mu ikoranabuhanga ryerekanwe ryatangiye nyuma yimyaka icumi, mu 1907 havumbuwe Electroluminescence. Ibi bintu bisanzwe byatanga iterambere ryambere mubuhanga bwa LED. 1952 yabonye iterambere rya ecran ya mbere ihishe, kandi yashyizwe mu makinamico make yo muri Amerika. Iri koranabuhanga ntirishobora kuboneka kubakoresha imyaka mirongo itanu.

Intambwe nini yakurikiyeho mu mateka ya ecran ni uguhimba itara rya mbere rya LED mu 1961. Robert Biard na Gary Pittman bahaye urumuri rwa mbere rwa LED itara rya LED ibikoresho bya Texas. Umwaka ukurikira Nick Holonyack yatanze urumuri rwa mbere rwa LED. Nyuma yimyaka ibiri, mu 1964, tekinoroji ya ecran yakoze indi ntera nini ihimbye LCD na plasma ya ecran yakozwe numuhimbyi wumunyamerika James Fergason.

Mugihe tekinoroji yo kwerekana terefone ari shyashya, iyambere muri iyerekanwa yavumbuwe mu 1965 kandi niyo yambere yakoreshejwe mugucunga ikirere. HDTV nayo yatangiriye mu Buyapani mu myaka ya za 1960 na 1970, nubwo HDTV zitageze muri Amerika kugeza mu 1998. Mu gihe abantu bageraga kuri ecran ya 90, OLEDs yahimbwe na Kodak bityo ibona ecran ya mbere yuzuye amabara yuzuye plasma.

Igitangaje, inganda zerekana zagutse vuba kandi zizakomeza kubikora. Mugaragaza ubunini butandukanye, imiterere nubuhanga bizakomeza gutezwa imbere mubikorwa bitandukanye. Nkigisubizo, akamaro ka sisitemu yo gupima neza ecran nayo izatera imbere cyane. Konica Minolta ifite sisitemu nyinshi zo gupima kugirango zihuze ibikenewe mu nganda zerekana.
