Dhawaan, kooxda cilmi-baarista ee BOE ayaa daabacday warqad cinwaankeedu yahay Xirmada Novel Naqshadeynta Waxay Kordhisaa Waxtarka indhaha ee Micro LED Bandhigyada joornaalka Macluumaadka.
Habka Naqshadeynta Baakadaha Qaab-dhismeedka Microstructure- Micro LED (Isha Sawirka: Muujinta Macluumaadka)
Daraasadu waxay soo jeedinaysaa nidaamka baakadaha Micro LED hal-abuur leh, si guul leh wax looga qabanayo caqabadaha farsamada warshadaha sida sii daynta darbiga xooggan ee chips-ka LED-ka, hufnaanta ka faa'iidaysiga tamarta iftiinka hooseeya, iyo isbeddelka midabka.
Waxaa la sheegay in marka cabbirka pixel-ku uu hoos u dhaco 50μm, halka qaraabada ah ee dhinaca gidaarka chip-ku uu kordho, taasoo horseedaysa sii daynta dambe ee kor loo qaaday iyo hoos u dhaca qiiqa sare ee Micro LEDs. Tani waxay sababtaa luminta dhalaalka iyo leexashada midabka, xaddidaysa codsiga Micro LEDs ee muuqaallada soo bandhigida saxda ah ee saxda ah.
Si arrintan wax looga qabto, kooxda cilmi-baarista ee BOE waxay soo saareen qaab-dhismeed baakad isku dhafan oo ka kooban koollo hufan-soo-celin-sare leh, resin cad oo milicsi sare leh, arrays microlens, iyo matrix madow qaabaysan (BM).
Iyadoo la soo bandhigayo lakabka index refractive gradient on Micro LED chips, cilmi-baarayaashu waxay si wax ku ool ah u wanaajiyeen xagasha iftiinka ee xagga sare ee chip, kordhinta xagasha muhiimka ah ee 25 darajo ilaa ugu badnaan 65.9 darajo oo si weyn u wanaajinaya waxtarka sare ee soo saarista iftiinka.
Dhanka kale, resinka cad ee milicsiga wuxuu sameeyaa qaabdhismeedka trapezoidal isosceles ee u dhexeeya chips, kaas oo xoogga saari kara oo kala firdhi kara iftiinka, kordhinta iftiinka xagasha 0 ° qiyaastii 27%. Intaa waxaa dheer, habka balasmaha si meesha looga saaro xabagta haraaga ah waxay hubisaa qiiqa iftiinka ee aan xannibnayn.
Marka la eego xakamaynta iftiinka, kooxdu waxay adeegsatay tignoolajiyada lithography ee nanoimprint si ay u abuuraan arraysyada microlens-ka saxda ah ee saxda ah, iyaga oo gaarey isku dhafka iftiinka ee gudaha ± 60°.
Natiijooyinka jilitaanka ayaa muujinaya in marka qallooca lensku yahay 0.03 iyo index refractive-ku yahay 1.85, xoojinta iftiinka ayaa kor u kacda 53%. Intaa waxaa dheer, daraasaddu waxay soo bandhigtay matrix madow oo qaabaysan lakabka dhalada ee baakadaha, si wax ku ool ah u yareeya milicsiga wax ka yar 2% iyo gaaritaanka saamiga isbarbardhigga sarreeya ee ka sarreeya 20,000: 1, si weyn u hagaajinaya tayada bandhigga.

Kooxda cilmi-baarista ee BOE waxay sheegeen in nidaamkani aanu kaliya ku guulaysan horumarrada hufnaanta indhaha iyo isku-duubnida laakiin sidoo kale ay tixgeliso isku halaynta baakadaha. Isku darka daboolka muraayadda iyo lakabka OCA (Optically Clear Adhesive) waxay kor u qaadaysaa biyuhu, anti-oxidation, iyo guryaha u adkaysta, siinta waddo lagu kalsoonaan karo oo loogu talagalay codsiga wax soo saarka ballaaran ee Micro LEDs ee beeraha sida bandhigyada baabuurta, AR / VR headsets, iyo qalabka xiran.
BOE kaliya ma aysan gaarin natiijooyinka cilmi baarista Micro LED ee ugu dambeeyay, laakiin sidoo kale waxay sii wadaa inay kor u qaaddo horumarinta tignoolajiyada tooska ah ee Mini / Micro LED iyo codsiyada.
