Dhawaan, kooxda cilmi-baarista ee BOE waxay daabacday warqad cinwaankeedu yahay Naqshadeynta Xirmooyinka Cusub waxay Kor u qaadaysaa Waxtarka Indhaha ee Bandhigyada Micro LED ee joornaalka Bandhigga Macluumaadka.
Habka Naqshadaynta Baakadaha ee Micro-Shuqulka Muujinta ee Micro-LED (Isha sawirka: Bandhigga Macluumaadka)
Daraasaddu waxay soo jeedinaysaa qorshe cusub oo baakadaha Micro LED ah, kaas oo si guul leh wax uga qabanaya caqabadaha farsamo ee warshadaha sida sii deynta derbiga ee adag ee jajabyada yaryar ee LED-ka, hufnaanta isticmaalka tamarta iftiinka oo hooseeya, iyo isbeddelka midabka.
Waxaa la soo sheegay in marka cabbirka pixel-ka uu hoos u dhaco ilaa 50μm, aagga qaraabada ah ee darbiga dhinac ee jajabku uu kordho, taasoo horseedaysa sii deynta dhinaca oo sii kordheysa iyo hoos u dhaca qiiqa sare ee Micro LEDs. Tani waxay keentaa luminta dhalaalka iyo leexashada midabka, taasoo xaddidaysa isticmaalka Micro LEDs xaaladaha bandhigga saxsan ee sare.
Si wax looga qabto arrintan, kooxda cilmi-baarista ee BOE waxay samaysay qaab-dhismeed baakado isku dhafan oo ka kooban dhejis hufan oo muujinaya tusmada sare, resin cad oo leh nuurad sare, taxane microlens ah, iyo matrix madow oo qaabaysan (BM).
Iyagoo soo bandhigaya lakabka tusmada refractive gradient ee jajabyada Micro LED, cilmi-baarayaashu si wax ku ool ah ayay u hagaajiyeen xagasha ka baxda iftiinka ee ka soo baxda sare ee jajabka, iyagoo kordhinaya xagasha muhiimka ah laga bilaabo 25 digrii ilaa ugu badnaan 65.9 digrii isla markaana si weyn u wanaajinaya hufnaanta soo saarista iftiinka sare.
Dhanka kale, resin-ka cad ee milicsiga leh wuxuu sameeyaa qaab-dhismeed trapezoidal isosceles ah oo u dhexeeya jajabyada, kaas oo xoogga saari kara oo kala firdhin kara iftiinka, taasoo kordhinaysa dhalaalka xagasha daawashada 0° qiyaastii 27%. Intaa waxaa dheer, habka plasma-ga si looga saaro dhejiska haraaga ah wuxuu hubiyaa in iftiinka aan la xannibin.
Marka laga hadlayo xakamaynta iftiinka, kooxdu waxay isticmaashay tignoolajiyada lithography-ga nanoimprint si ay u sameeyaan taxane microlens ah oo sax ah, iyagoo gaaray isku-dhafnaan wax ku ool ah oo iftiinka ah gudaha ± 60°.
Natiijooyinka jilitaanka ayaa muujinaya in marka qalooca muraayadda uu yahay 0.03 oo tusmada iftiinka ay tahay 1.85, xoogga iftiinku uu kordho in ka badan 53%. Intaa waxaa dheer, daraasaddu waxay ku soo bandhigtay matrix madow oo qaabaysan lakabka galaaska baakadaha, taasoo si wax ku ool ah u yareysay iftiiminta ilaa wax ka yar 2% isla markaana gaartay saami isbarbardhig sare oo ka sarreeya 20,000:1, taasoo si weyn u wanaajisay tayada bandhigga.

Kooxda cilmi-baarista ee BOE waxay sheegeen in qorshahani uusan kaliya gaarin horumarro ku saabsan hufnaanta indhaha iyo isku-midnimada laakiin sidoo kale uu tixgeliyo isku-kalsoonaanta baakadaha. Isku-darka daboolka galaaska iyo lakabka OCA (Optically Clear Adhesive) wuxuu xoojiyaa sifooyinka biyaha aan biyuhu karin, ka-hortagga oksaydhka, iyo kuwa u adkaysta xirashada, taasoo bixinaysa waddo lagu kalsoonaan karo oo loogu talagalay isticmaalka wax-soo-saarka ballaaran ee Micro LEDs-ka meelaha sida bandhigyada baabuurta, madax-madaxyada AR/VR, iyo aaladaha la xiran karo.
BOE ma aysan gaarin oo keliya natiijooyinkii ugu dambeeyay ee cilmi-baarista Micro LED laakiin waxay sidoo kale sii waddaa inay kor u qaaddo horumarinta tignoolajiyada iyo codsiyada bandhigga tooska ah ee Mini/Micro LED.
