Ukuphumelela kwiMikrolo ye-LED yokuBonisa: IPixel ye-LED encinci yeHlabathi kwi-90nm nje

Kumtsi omkhulu wokutsibela phambili kwitekhnoloji yokubonisa, abaphandi abavela kwiDyunivesithi yaseZhejiang baveze eyona pixel incinci ye-LED yehlabathi - ukulinganisa nje90 nanometers (nm)— ukuseta ibhenchmark entsha kwisisombululo kunye nokusebenza kakuhle kwimiboniso yesizukulwana esilandelayo.

Ikhokelwa nguNjingalwazi uDavid Di kunye noNjingalwazi uBaodan Zhao, iqela lophando lipapashe iziphumo zalo kwiIndalophantsi kwesihloko"Ukunciphisa ii-LED ezincinci kunye ne-nano-perovskite."Umsebenzi wabo wazisa i-ultra-high-resolution uluhlu lwe-LED olukwazi ukufezekiswa127,000 pixels nge-intshi nganye (PPI)-esona sisombululo siphezulu sakha sarekhodwa kwitekhnoloji yokubonisa i-LED.

Kutheni le nto ibalulekileyo

Imiboniso ye-Micro LED ye-III-V ye-semiconductor-based ijongene nemida ebalulekileyo:

• Iindleko eziphezulu zokuvelisa

• Ukusebenza okubukhali kokwehla xa kulinganiswe ngaphantsi kwe-10 microns

Isisombululo esitsha? IPerovskite LEDs (PeLEDs), ezibonelela ngeenzuzo ezininzi eziphambili:

• Iindleko ezisezantsi zemveliso

• Ukusebenza okugqwesileyo kwimilinganiselo ye-nanoscale

• I-quantum efficiencies yangaphandle (EQE) ye-20-30%, xa ithelekiswa ne-OLEDs

• Ubomi obude bokusebenza busondela kwimigangatho ye-OLED

Olu lutsha luvula umnyango wokusebenza okuphezulu, imiboniso enexabiso eliphezulu eyayingafumaneki ngaphambili ngeteknoloji ye-Micro LED eqhelekileyo.

I-Innovation emva kwePixel-Breaking Record

Embindini wale mpumelelo bubuchule bokwenza inoveli eyaziwa ngokuba yiinkqubo yoqhagamshelwano yendawo. Indlela isebenzisa i-insulating layer kunye neefestile ezinepateni zokuthintela ukuvezwa ngokuthe ngqo kwezinto ze-perovskite kwi-electrodes, ukunciphisa kakhulu ukulahleka kwamandla angenawo umbane.

Ngenxa yoko, ii-PeLED zigcina ukusebenza kakuhle nakwi-ultra-small sizes - isiganeko esibalulekileyo kwizicelo eziphezulu zexesha elizayo.

Uthelekiso lokuSebenza: PeLED vs Traditional Micro LED

Ii-PeLEDs zigqithisa ngokucacileyo ii-LED zemveli ze-Micro kuzo zombini ukulinganisa kunye nokusebenza kakuhle kwizikali ezincinci, zibenza babe ngabaviwa abafanelekileyo bobuchwephesha bokubonwayo obulandelayo.

Iprototype esebenzayo-yeMatrix iMboniso yePeLED encinci

Iqela liphinde labonisa iprototype esebenzayo ye-matrix micro-PeLED ukubonisa usebenzisa i-trash-film transistor (TFT) i-backplanes yezorhwebo - ebonisa ukusebenza kwayo kwizicelo ezisebenzayo, eziphezulu.

Iimeko ezinokuthi zisetyenziswe ziquka:

• Inyani eyongeziweyo (i-AR) kunye neNyaniso eyiNqobo (VR)-Ukucaca kwinqanaba le-retina kunye ne-PPI ephezulu kakhulu

• Imiboniso eNxitywayo-Ikhaphukhaphu kwaye isebenzise amandla

• Iiglasi eziSmart kunye neziBoniso zentloko-phezulu (HUDs)-Ukukhanya okuphezulu kunye nokusetyenziswa kwamandla aphantsi

Imingeni kunye neNdlela ePhambili

Ngaphandle koku kuphumelela, imingeni emininzi isele ngaphambi kokuba ii-PeLED zifikelele kwimveliso yobuninzi:

1. Ubomi kunye nokuzinza: Nangona ii-PeLED zangoku zisondela kwi-OLED-like lifespans, uphuculo olongezelelweyo luyafuneka ekuhanjisweni kwezorhwebo.

2. Ukubaleka: Ukutshintsha ukusuka kwiprototypes yelebhu ukuya kwimveliso yomthamo omkhulu kuya kufuna izinto ezintsha ezifana noshicilelo lwe-inkjet kunye ne-roll-to-roll processing.

3. Ukhuphiswano: I-Micro OLED kunye ne-quantum dot-enhanced Micro LED technologies nazo zihambela phambili ngokukhawuleza.

Nangona kunjalo, ingxinano ye-pixel engazange ibonwe ngaphambili ye-PeLED ibanika umda okhethekileyo kwi-niche, iimakethi ezinesisombululo esiphezulu.

Imboniselo yoShishino: Ukukhula kwiThin-Film Micro LED

Iqhutywa yimfuno yemiboniso ye-ultra-high-resolution kunye nenkqubela phambili kwitekhnoloji ye-hybrid ye-LED, imakethi yehlabathi yefilimu encinci ye-Micro LED ilungele ukukhula olomeleleyo. Amacandelo aphambili aphembelela olu lwando aquka:

• Ii-headsets ze-AR/VR

• Ii-HUD zeemoto

• Izinxibo ezihlakaniphile

Ngokohlalutyo lwamva nje lweshishini, ezi ndlela ziya kukhawulezisa utyalo-mali kunye ne-R&D kwi-perovskite kunye nobuchwephesha bokubonisa obunxulumeneyo.

Isiphelo: Ixesha elitsha leMiboniso ye-Micro LED

Uphuhliso lweI-90nm yePixel yePeLEDiphawula inguqu kwinguquko yetekhnoloji yokubonisa. Nge:

• Ubuninzi bepixel obungazange bubonwe (127,000 PPI)

• Iindleko ezisezantsi zokuvelisa xa kuthelekiswa ne-III-V Micro LEDs

• Ukusebenza okuzinzileyo kwiisayizi ze-nanoscale

Iziboniso ze-Micro LED ezisekelwe kwi-Perovskite zibekwe kakuhle ukukhokela i-wave wave entsha - ngakumbi kwi-AR / VR, izixhobo ezinxitywayo, kunye nezinye izicelo ezibonakalayo eziphezulu.

Njengoko uphando luqhubeka kwaye iindlela zokuvelisa zikhula, ii-PeLEDs zinokukhawuleza zibe ngumgangatho we-ultra-high-definition displays kuwo onke amashishini.
