Nekuenderera mberi kwekuvandudzwa kweMicroChiratidziro che LED, kubudirira kwakawanda kwakaitwa muruzivo rwokugadzira zvinhu.Munguva pfupi yadarika, kwave nekuitika kutsva kutsva muMicro LED kuratidza, uye kwave nekuwanda kutsva tekinoroji kubudirira munyika.
Yonsei University inogadzira yakakwirira-resolution tri-ruvara Micro LED kuratidza tekinoroji
Zvinonzi timu yaProfessor Jong-hyun Ahn weDhipatimendi reMagetsi neElectroniki Injiniya yeYonsei University yakashandisa MoS2 semiconductors uye quantum dots kuti iwane yakakwirira-resolution tri-color Micro LED kuratidza tekinoroji. Iyo tekinoroji, yakabudiswa mu "Nature Nanotechnology ," uye ndiyo yekutanga pasi rose kugadzira tekinoroji yakabatanidzwa ichishandisa maviri-dimensional semiconductors uye quantum dots, inotarisirwa kushandiswa mukuvandudza chizvarwa chinotevera chepamusoro-soro augmented reality (AR) uye virtual reality (VR) kuratidza.Ishoko rakanaka kuneLED indasitiri.
Kugadzira Micro LED kuratidzwa, maitiro akaoma ega ega ega matatu-mavara Micro LED machipi kune backplane redunhu bhodhi inodiwa.Kunyange zvazvo iyi nzira yekugadzira yakakodzera kugadzirwa kwezviratidziro zvakakura nekugadzirisa kwakaderera, haigoni kuzadzisa zvinodiwa zvechizvarwa chinotevera augmented real (AR) uye chaiyo chaiyo (VR) zviratidzo zvinoda kugadziriswa kwepamusoro uye kushanda kwepamusoro-soro.
Kukunda zvipimo zvehunyanzvi zvekugadzira Micro LED kuratidza, timu yekutsvagisa yakagadzira maviri-dimensional semiconductor molybdenum disulfide (MoS2) yakananga pane gallium nitride (GaN) wafer yeblue LEDs, uyezve yakabatanidza semiconductor maseketi kugadzira ega semiconductor maseketi , zvakabudirira kuona yekutanga yenyika 500 PPI (nhamba yeMicro LED magetsi masosi pa inch), yakakwirira-resolution Micro LED kuratidza pasina kutamisa maitiro.Pamusoro pezvo, timu yekutsvagisa yakagadzirawo nzira yekuzadzisa matatu ekutanga mavara nekudhinda madotsi ehuwandu pablue GaN Micro LEDs, iyo inogona kuvandudza zvakanyanya maitiro ekuratidzwa uye kuderedza mutengo wekugadzira.Uye zvakare, tekinoroji yakagadziridzwa neboka rekutsvagisa haingogone kurerutsa iyo yakaoma kugadzira maitiro eMicroLED inoratidza chigadzirwa, asi zvakare kuwana yakakwirira resolution.
Yunivhesiti yeKyung Hee inogadzira ultra-dense optics array yemidziyo yeAR
Munguva pfupi yadarika, timu yekutsvagisa inotungamirwa naProfessor Lee Seung-hyun weDhipatimendi reElectroniki Injiniya yeKyung Hee University yakashandisa ekupedzisira-yakanyanya kusanganisa madiki-emitting diode (akazonzi maMicro LEDs) kugadzira optical element arrays ane pixel saizi yeguruva. zvimedu uye quantum dots uye yakanakisa ruvara.Restorative.Mitsetse yezvinhu zvemaziso zvinotarisirwa kushandiswa kugadzira augmented reality mifananidzo paziso.Fusion yakaoma nekuda kwekusiyana kwekugadzira substrates yemagetsi maseketi uye Micro LEDs.Kazhinji, maseketi emagetsi anogadzirwa pasilicon substrates, nepo Micro LEDs inogadzirwa pagallium nitride substrates.Kugadzirisa dambudziko iri, boka raProfessor Li rekutsvagisa rakagadzira nzira inogona kutamisa zvidimbu zvitete zvegallium nitride, chinenge chikamu chimwe mugumi chekukora kwebvudzi remunhu, pasilicon substrate.
Zvichienderana nehunyanzvi uhu, timu yekutsvagisa yakabudirira kuumba diki pasirese particle size (5μm) LED pixel nekushandisa chete silicon wedunhu tekinoroji uye pasina general kuratidza maitiro."Nzira yekufambisa inokanganiswa zvakanyanya nekuwedzera kwemafuta, saka takatarisa kugadzira zvidimbu zvitete zvealloy pakudziya kwakaderera," akatsanangura mudzidzi weinjiniya yemagetsi Shin Yoo-seop.Panguva imwecheteyo, timu yekutsvagisa yakashandisa tekinoroji yequantum dot kuvandudza mwero wekubereka kwemavara, ichiwedzera pfungwa yechokwadi kuAR.Quantum madotsi akakwezva kutariswa kwakawanda sechinotevera-chizvarwa chinoburitsa chiedza nekuda kwekuchena kweruvara uye kusimba kwemifananidzo zvichienzaniswa neyakajairwa-zvinobudisa mwenje zvinhu nekuti zvinogona kugadzirwa nekugadzira hurefu hwakasiyana hwemwenje wavelengths kune yega yega saizi pasina kushandura mhando.zvinhu zvemavara akasiyana-siyana.Nekudaro, madotsi e quantum anotapukirwa neakasiyana masolvents anoshandiswa mune general semiconductor processing.
Kugadzirisa dambudziko iri, timu yekutsvagisa yakagadzira "yepamusoro-resolution yakaoma nzira yekufambisa" iyo inogona kusarudza pateni zvinoenderana nepamusoro pesimba simba.Ivo vakabudirira kushandisa quantum dot tekinoroji kuwana RGB ruvara pasina solvent.Iwo akagadziridzwa optical pixels madiki kwazvo kunyangwe akatariswa nemaikorosikopu, achiaita kuti aenderane nemidziyo midiki senge zvinopfekwa.Mukuwedzera, iyo optical element pixels inogona zvakajekaled projectaugmented reality mifananidzo nekuratidza yakakwira color gamut.
