Linewidth kugoverwa kweakasiyana inkjet kudhinda matekinoroji
Parizvino, matekinoroji maviri makuru ekuratidzira, liquid crystal display (LCD) uye organic light-emitting diode (OLED), akaiswa kune ari pedyo-ziso anoratidza (NEDs) uye misoro-yakaiswa kuratidza (HMDs).Nekudaro, kuvandudzwa kwehunyanzvi hwekuratidzira matekinoroji kwakakwidziridzwa nekuda kwezvisina kunaka senge yakaderera shanduko inoshanda, kuzara kwemavara, uye nekukurumidza kuchembera uye hupenyu hupfupi.
Iine yakanakisa optical performance uye hupenyu hurefu,Micro LEDinoonekwa seyekupedzisira-inotevera-chizvarwa kuratidza tekinoroji.Iyo shoma pixel saizi inosvika makumi emakroni, uye iyo yakakwira pixel density inoita kuti igone kushandiswa muAR/VR.
Nekukurumidza kukura kwehungwaru hwekugadzira, kucherechedzwa kwechifananidzo uye 5G kutaurirana matekinoroji, augmented reality (AR) uye virtual reality (VR) matekinoroji ari kukura pamwero unotyisa.Muchirevo chedenda idzva rekorona, telecommuting uye kushamwaridzana kwevatengi vari kure kuri kuwedzera, uye musika wakatendeudzira zvakare kutarisisa kwayo kuAR / VR, uye kudyara mukushandisa tekinoroji kwawedzera.
Sekureva kweIDC, kubva muna 2020 kusvika 2024, saizi yemusika wepasi rose maindasitiri eAR neVR achakura kubva pamabhiriyoni makumi maviri nemasere eyuan uye mabhiriyoni makumi matanhatu nemaviri eyuan kusvika 240 bhiriyoni, zvichiteerana.Chimwe chezvikonzero zvikuru zvekuputika kwemusika ndiko kubuda kwehunyanzvi hwekuratidzira tekinoroji nekuita kwakanaka.Sechinhu chakakosha cheAR/VR, zvishandiso zvekuratidzira zvinofanirwa kuve nazvoUltra-yakakwirira pixel densityuye nekukurumidza kuzorodza kumhanya kuwedzera kune huremu huremu uye saizi diki.
Iri bepa rinotanga kusuma kufambira mberi kwekutsvagisa kweAR/VR tekinoroji, rozokurukura kufambira mberi kwekutsvagisa kweMicroChiratidziro che LEDtekinoroji uye kuchinjika kwayo muAR / VR, pamwe chete nezvakanakira kugadzirira Micro LED color shanduko layer ne inkjet kudhinda tekinoroji.Iyo isiri-radiative simba rekufambisa mashandiro uye mhedzisiro yehupamhi hwemuvara wekushandura dhizaini pane yekuchinja kwemavara kushanda;hukuru hweSIJ mukugadziriswa kana ichienzaniswa nemamwe matekinoroji ekudhinda inounzwa.
Matsamba uye logo yechikoro yakadhindwa neSIJ tekinoroji
Pamusoro pehupamhi hwepixel density, ruvara ruzere zvakare chinhu chakakosha kuona Micro LED muAR/VR.Pakati pavo, ruvara rwekushandura chirongwa inzira inoshanda yekuwana yakazara ruvara.Quantum dots akaiswa pablue kana ultraviolet Micro LED machipisi ne inkjet kudhinda tekinoroji.Matatu-mavara luminescence anowanikwa, uku achinzvenga giant quantitative transfer.
Mumakore achangopfuura, matekinoroji akadai sepiezoelectric/thermal inkjet printing, aerosol inkjet printing, electrohydrodynamic inkjet printing, uye super inkjet kudhinda kwakashandiswa kuisa mavara ekushandura mavara, zvichiratidza kugona kukuru kwekuona yakazara-ruvara Micro LEDs.Nguva pfupi yadarika, chikwata chaProf. Zhang Rong veku Xiamen University, vachibatsirana naProf. Guo Haozhong vanobva kuTaiwan Chiao Tung University, vakaburitsa bepa rine musoro unoti “Principle of Inkjet Printing Technology and Its Application in AR/VR Microdisplays” muOpto-Electronic Advances. Chinyorwa 5, 2022 "Chinyorwa chekuongorora.
Chikamu chechipiri chinozivisa misimboti yekudhinda yeakasiyana inkjet tekinoroji, uye nyaya mbiri dzinokosha: optimization ye rheological parameters yeinki uye mhinduro yekofi ring effect.
Iyo rheological parameters yeinki yakakodzera kune yega yega tekinoroji yekudhinda uye pesvedzero yerheological parameters painodhinda mhedzisiro inounzwa.Mhinduro mbiri dzekofi mhete mhedzisiro uye dzakananga nzira dzekuvandudza dzinoongororwa.Chekupedzisira, mamwe matambudziko angangove ane chekuita neshanduko yemavara akaiswa akaiswa pachena, anosanganisira optical crosstalk, bhuruu mwenje wekubata, uye wega-absorption mhedzisiro.
Micro LED inovhura nzira yekutengesa kweAR / VR, uye kugadzirwa kweiyo yakazara-ruvara Micro LED ine yakakwira pixel density ndeimwe yemabhodhoro.Iyo color conversion layer scheme inzira inoshanda yekuona yakazara-ruvara Micro LED, uye kuvandudzwa kweinkjet yekudhinda tekinoroji inopa rutsigiro rwehunyanzvi pakugadzirirahigh-resolutionmavara ekushandura mavara.
