Hamwe niterambere rihoraho rya MicroLED yerekana, intambwe nyinshi zakozwe mu ikoranabuhanga.Vuba aha, habaye iterambere rishya muri Micro LED yerekanwe, kandi habaye iterambere rishya ryikoranabuhanga kwisi.
Kaminuza ya Yonsei itezimbere tekinoroji ya tri-amabara ya Micro LED yerekana tekinoroji
Biravugwa ko itsinda rya Porofeseri Jong-hyun Ahn wo mu ishami ry’amashanyarazi n’ikoranabuhanga rya kaminuza ya Yonsei ryakoresheje semiconductor ya MoS2 n’utudomo twa kwant kugira ngo tugere ku buhanga buhanitse bwa tri-amabara Micro LED yerekana ikoranabuhanga. Ikoranabuhanga, ryasohotse muri "Kamere Nanotehnologiya "Ni inkuru nziza kuriInganda LED.
Kugirango ukore Micro LED yerekana, biragoye inzira yo kwimura kugiti cyayo amabara atatu Micro LED chip kumurongo winyuma windege.Mugihe ubu buryo bwo gukora bukwiranye nogukora ibyerekanwa binini bifite imiterere mike, ntibishobora kuzuza ibisabwa ibisekuruza bizaza byongerewe ukuri (AR) hamwe nukuri kugaragara (VR) bisaba gukemura cyane no gukora byihuse.
Kugira ngo tuneshe imbogamizi tekinike yo guteza imbere Micro LED yerekana, itsinda ry’ubushakashatsi ryashizeho ibice bibiri-bibiri bya semiconductor molybdenum disulfide (MoS2) kuri wafer ya gallium nitride (GaN) ya LED yubururu, hanyuma ihuza imiyoboro ya semiconductor kugirango ikore imiyoboro ya semiconductor, yatahuye neza PPI 500 yambere kwisi (umubare wa Micro LED itanga urumuri kuri santimetero), Micro LED yerekana neza nta nzira yo kohereza.Byongeye kandi, itsinda ry’ubushakashatsi ryanashyizeho uburyo bwo kugera ku mabara atatu y’ibanze hifashishijwe icapiro rya kwant kuri LED LED yubururu GaN Micro, rishobora kuzamura umusaruro w’ibikorwa no kugabanya ibiciro by’umusaruro.Byongeye kandi, tekinoroji yatunganijwe nitsinda ryubushakashatsi ntishobora gusa koroshya inzira igoye yo gukora MicroLED yerekana ibicuruzwa, ariko kandi ugere kumurongo wo hejuru.
Kaminuza ya Kyung Hee itezimbere ultra-dense optique igizwe nibikoresho bya AR
Vuba aha, itsinda ry’ubushakashatsi riyobowe na Porofeseri Lee Seung-hyun wo mu ishami ry’ubuhanga bwa elegitoroniki rya kaminuza ya Kyung Hee ryakoresheje mikorobe ikwirakwiza cyane ya diode (nyuma yiswe Micro LEDs) mu guhimba ibintu bya optique bifite pigiseli nini y’umukungugu. ibice na kwantu utudomo nibara ryiza.Kugarura.Ibice bya optique byitezwe gukoreshwa mugushushanya amashusho yongerewe ukuri kumaso.Guhuza biragoye kubera itandukaniro mubikorwa byo gukora insimburangingo ya elegitoronike na Micro LEDs.Mubisanzwe, imiyoboro ya elegitoronike ihimbwa kuri sisitemu ya silicon, mugihe Micro LEDs ihimbwa na gallium nitride.Kugira ngo iki kibazo gikemuke, itsinda ry’ubushakashatsi bwa Porofeseri Li ryashyizeho uburyo bushobora kwimura nitride ya gallium, hafi kimwe cya cumi cy’ubunini bw’imisatsi y’umuntu, kuri substrate ya silicon.
Hashingiwe kuri iri koranabuhanga, itsinda ry’ubushakashatsi ryatsinze neza pigiseli ntoya ku isi (5μm) LED ikoresha tekinoroji ya silikoni gusa kandi nta buryo rusange bwo kwerekana.Umunyeshuri w’ishami ry’amashanyarazi Shin Yoo-seop yabisobanuye agira ati: "Ubuhanga bwo kwimura bugira ingaruka cyane ku kwaguka kw’ubushyuhe, ku buryo twibanze ku gukora ibice bito bito cyane ku bushyuhe buke".Muri icyo gihe, itsinda ry’ubushakashatsi ryakoresheje ikoranabuhanga rya kwant kugirango ritezimbere igipimo cy’imyororokere, ryongera imyumvire ya AR.Utudomo twa Quantum twashimishije cyane nkibisekuru bizakurikiraho bitanga urumuri kubera ibara ryabyo ryinshi kandi bifotora ugereranije nibikoresho bisanzwe bitanga urumuri kuko bishobora kubyara kubyara uburebure butandukanye bwumurambararo wumucyo kuri buri gipimo kidahinduye ubwoko.ibikoresho by'amabara atandukanye.Ariko, utudomo twa kwant dushobora kwangirika kumashanyarazi atandukanye akoreshwa mugutunganya igice cya kabiri.
Kugira ngo iki kibazo gikemuke, itsinda ry’ubushakashatsi ryateguye "uburyo bukomeye bwo kwimura bwumye" bushobora guhitamo ukurikije ingufu z’ubutaka.Bashoboye gukoresha tekinoroji ya dant kugirango bagere ibara rya RGB nta solvent.Iterambere rya optique ya optique ni nto cyane niyo urebye ukoresheje microscope, bigatuma ikoreshwa kubikoresho bito nkibishobora kwambara.Mubyongeyeho, optique ya optique ya pigiseli irashobora kugaragara nezayayoboye umushingayongerewe amashusho mubyukuri mugaragaza amabara maremare.
