Iyadoo horumarinta joogtada ah ee MicroMuujinta LED, horumarro badan ayaa laga sameeyay tignoolajiyada.Dhawaan, waxaa jiray horumarro cusub oo soo noqnoqda oo ku saabsan bandhigyada Micro LED, waxaana jiray horumaro tignoolajiyadeed oo badan oo adduunka ah.
Jaamacadda Yonsei waxay soo saartaa tignoolajiyada bandhiga saddex-midabka leh ee cabbirka sare leh
Waxaa lagu soo waramayaa in kooxda Professor Jong-hyun Ahn oo ka tirsan Waaxda Korontada iyo Electronic Engineering ee Jaamacadda Yonsei ay isticmaaleen MoS2 semiconductors iyo dhibcaha quantum si ay u gaaraan heerka sare ee tri-midabka Micro LED bandhigay technology. The technology, daabacay in "Nature Nanotechnology " waana kan ugu horreeya adduunka ee horumarinta tignoolajiyada isku dhafan iyadoo la adeegsanayo laba-geesoodka semiconductors iyo dhibcaha quantum, ayaa la filayaa in loo isticmaalo horumarinta jiilka soo socda ee waxqabadka sare leh ee xaqiiqada la kordhiyey (AR) iyo xaqiiqada dhabta ah (VR).Waa war wanaagsanwarshadaha LED.
Si loo soo saaro muraayadda Micro LED, hannaan adag oo si gaar ah loogu wareejinayo chips-yada Micro LED-ka ee saddexda midab leh ayaa loo baahan yahay.Inkasta oo habkan wax-soo-saarku uu ku habboon yahay soo saarista bandhigyo waaweyn oo leh xallin hoose, ma dabooli karo baahida jiilka soo socda ee xaqiiqada la kordhiyey (AR) iyo xaqiiqada dhabta ah (VR) ee u baahan xallin sare iyo hawlgal xawaare sare leh.
Si looga gudbo xaddidaadyada farsamo ee horumarinta bandhigyada Micro LED, kooxda cilmi-baarista waxay sameeyeen laba-geesoodka semiconductor molybdenum disulfide (MoS2) si toos ah gallium nitride (GaN) wafer loogu talagalay LED-yada buluuga ah, ka dibna la isku daray wareegyada semiconductor si loo abuuro wareegyada semiconductor shaqsi. si guul leh u xaqiiqsaday 500 PPI ee ugu horreeya adduunka (tirada ilaha iftiinka Micro LED halkii inch), muuqaal sare oo Micro LED ah iyada oo aan habka wareejinta.Intaa waxaa dheer, kooxda cilmi-baaristu waxay sidoo kale soo saareen farsamo si ay u gaaraan saddex midabada aasaasiga ah iyaga oo daabacaya dhibcaha quantum ee buluugga GaN Micro LEDs, taas oo si weyn u wanaajin karta wax-soo-saarka habka bandhigga iyo yaraynta kharashka wax soo saarka.Intaa waxaa dheer, tignoolajiyada ay sameeyeen kooxda cilmi-baarista ma fududayn karto oo kaliya habka wax soo saarka adag ee MicroLED waxay soo bandhigtaa alaabta, laakiin sidoo kale la gaaro xal sare.
Jaamacadda Kyung Hee waxay soo saartaa qalabyada AR-ga ee cufan
Dhawaan, koox cilmi baaris ah oo uu hogaaminayo Professor Lee Seung-hyun oo ka tirsan Waaxda Injineerinka Elektrooniga ee Jaamacadda Kyung Hee waxay adeegsadeen diodes-iftiin aad u sarreeya oo isku dhafan (oo hadda loo yaqaan Micro LEDs) si ay u abuuraan qalabyo muuqaal ah oo leh cabbir pixels oo boodh ah. Qaybaha iyo dhibcaha quantum iyo midab aad u fiican.Soo celinQalabyo kala duwan oo walxaha indhaha ah ayaa la filayaa in loo isticmaalo in lagu soo bandhigo sawirada dhabta ah ee la kordhiyay ee isha.Fusion way adag tahay sababtoo ah kala duwanaanshaha wax soo saarka ee wareegyada elektiroonigga ah iyo Micro LEDs.Caadi ahaan, wareegyada elektaroonigga ah waxaa lagu farsameeyaa substrates silikoon, halka Micro LED-yada laga sameeyay substrates gallium nitride.Si loo xalliyo dhibaatadan, kooxda cilmi-baarista Professor Li ayaa soo saartay farsamo ku wareejin karta lakabyada khafiifka ah ee gallium nitride, qiyaastii toban meelood meel dhumucda timaha bini'aadamka, oo ku dhejin kara substrate silicon.
Iyada oo ku saleysan tignoolajiyadan, kooxda cilmi-baarista ayaa si guul leh u sameeyay cabbirka qurubyada ugu yar adduunka (5μm) pixel LED iyaga oo isticmaalaya kaliya tignoolajiyada wareegga silikoon oo aan lahayn nidaam bandhig guud."Farsamada wareejinta waxaa si weyn u saameeya ballaarinta kulaylka, sidaas darteed waxaan diiradda saarnay sameynta lakabyo khafiif ah oo heerkul hooseeya," ayuu yiri arday injineernimada korontada Shin Yoo-seop.Isla mar ahaantaana, kooxda cilmi-baaristu waxay codsadeen tignoolajiyada dhibicda quantum si ay u hagaajiyaan heerka taranka midabka, iyaga oo ku daray dareenka dhabta ah ee AR.Dhibcaha Quantum-ka ayaa soo jiitay fiiro gaar ah sida qalabka soo socda ee soo socda sababtoo ah nadiifnimadooda midabka sare iyo sawir-qaadista marka la barbardhigo qalabka caadiga ah ee iftiiminta sababtoo ah waxaa lagu soo saari karaa iyadoo la dhalinayo dhererka kala duwan ee hirarka iftiinka ee cabbir kasta oo qayb ah iyada oo aan la beddelin nooca.alaab midabyo kala duwan leh.Si kastaba ha ahaatee, dhibcaha quantumku waxay u nugul yihiin dareerayaasha kala duwan ee loo isticmaalo habaynta guud ee semiconductor.
Si loo xalliyo dhibaatadan, kooxda cilmi-baaristu waxay soo saareen "qaabka wareejinta qalalan ee heer sare ah" kaas oo si xushmad leh u qaabayn kara iyadoo loo eegayo xoojinta tamarta dusha sare.Waxay ku guulaysteen adeegsiga tignoolajiyada dhibicda quantum si ay u gaadhaan midabka RGB iyada oo aan dareere lahayn.pixels-yada la sameeyay waa kuwo aad u yar xitaa marka lagu eego mikroskoob, taasoo ka dhigaysa inay ku habboon yihiin aaladaha yaryar sida kuwa la xidho.Intaa waxaa dheer, pixels element isha si cad u kartaamashruuca hogaaminayasawirada dhabta ah ee la kordhiyay iyadoo la soo bandhigay gamut midab sare leh.
