Okumenyawo mu Micro LED Display: Pixel ya LED esinga obutono mu nsi yonna ku 90nm zokka

Mu kubuuka okunene mu maaso mu tekinologiya w’okwolesebwa, abanoonyereza okuva mu Zhejiang University balaze ekifaananyi kya LED ekisinga obutono mu nsi yonna — ekipima justNanomita 90 (nm) .— okuteekawo omutindo omupya mu kusalawo n’obulungi bw’okwolesebwa okw’omulembe oguddako.

Nga bakulembeddwamu Professor David Di ne Professor Baodan Zhao, ttiimu y’abanoonyereza eno yafulumizza bye bazudde mu...Enkulawansi w’omutwe"Okukendeeza ku micro- ne nano-perovskite LEDs."Omulimu gwabwe guleeta ensengekera ya LED ey’obulungi ennyo (ultra-high-resolution LED array) esobola okutuukiriza127,000 pixels buli yinsi (PPI) .— obulungi obusinga obunene obubadde buwandiikiddwa mu tekinologiya w’okulaga LED.

Lwaki Okumenyawo Kuno Kukulu

Ebintu eby’ennono ebya III-V ebikozesa semikondokita ebya Micro LED byolekedde obuzibu obw’amaanyi:

• Ebisale by’okukola ebintu bingi

• Sharp efficiency drop nga scaled wansi wa ~10 microns

Ekipya eky’okugonjoola ensonga? Perovskite LEDs (PeLEDs), eziwa ebirungi ebikulu ebiwerako:

• Okukendeeza ku ssente ezisaasaanyizibwa mu kukola ebintu

• Omulimu omulungi ennyo ku bipimo bya nanoscale

• Obulung’amu bwa quantum obw’ebweru (EQE) obwa 20–30%, obugeraageranyizibwa ku OLEDs

• Obulamu obuwanvu obw’okukola nga busemberera omutindo gwa OLED

Obuyiiya buno buggulawo oluggi lw’ebintu eby’okwolesebwa eby’omutindo ogwa waggulu, ebitali bya ssente nnyingi, edda ebyali tebituukirizibwa na tekinologiya wa Micro LED owa bulijjo.

Obuyiiya Obuli Emabega Wa Pixel Emenye Likodi

Ku mutima gw’obuwanguzi buno kwe kukola enkola empya ey’okuyiiya emanyiddwa nga...enkola y’okukwatagana mu kitundu. Enkola eno ekozesa oluwuzi oluziyiza (insulating layer) nga lulina amadirisa agakola ebifaananyi okuziyiza okukwatibwa obutereevu ebintu bya perovskite ku electrodes, okukendeeza ennyo ku kufiirwa kw’amasoboza agatali ga radiative.

N’ekyavaamu, PeLEDs zikuuma obulungi obw’amaanyi ne ku sayizi entono ennyo — ekintu ekikulu ennyo mu nkola ez’obulungi obw’amaanyi mu biseera eby’omu maaso.

Okugerageranya emirimu: PeLED vs Traditional Micro LED

PeLEDs zisinga bulungi Micro LEDs ez’ennono mu byombi scalability ne efficiency ku minzaani entono, ekizifuula abalungi abagenda okukozesebwa mu tekinologiya ow’omulembe oguddako okulaba.

Prototype Active-Matrix Micro PeLED Okwolesebwa

Ttiimu era yalaga enkola ekola eya active-matrix micro-PeLED display nga ekozesa commercial thin-film transistor (TFT) backplanes — nga ekakasa nti esobola okukozesebwa mu nkola, ey’obulungi obw’amaanyi.

Ebiyinza okukozesebwa mulimu:

• Ebintu ebiyitibwa Augmented Reality (AR) ne Virtual Reality (VR) .– Okutegeera obulungi ku ddaala lya retina nga olina PPI eya waggulu ennyo

• Ebintu Ebiraga Okwambala– Ezitowa nnyo ate nga tekozesa maanyi ga maanyi

• Smart Glasses & Ebintu Ebiraga Omutwe (HUDs)– Obutangaavu obw’amaanyi nga bukozesa amaanyi matono

Okusoomoozebwa n’Ekkubo eriri mu maaso

Wadde nga waliwo okumenyawo kuno, okusoomoozebwa okuwerako kukyaliwo nga PeLED tennatuuka ku kukola mu bungi:

1. Obulamu n’Okutebenkera: Wadde nga PeLED eziriwo kati zisemberera obulamu obulinga obwa OLED, okwongera okulongoosa kwetaagibwa okusobola okuteekebwa mu nkola mu by’obusuubuzi.

2. Okusobola okulinnyisibwa: Okukyuka okuva ku prototypes ku mutendera gwa laabu okudda mu kukola ebintu ebinene kijja kwetaagisa obuyiiya nga okukuba ebitabo mu yinki n’okulongoosa okuva ku roll-to-roll.

3. Empaka: Tekinologiya wa Micro OLED ne quantum dot-enhanced Micro LED nayo agenda mu maaso mangu.

Wabula, pixel density etabangawo eya PeLEDs eziwa enkizo ey’enjawulo mu butale bwa niche, obw’obulungi obw’amaanyi.

Endowooza y’amakolero: Okukula mu Thin-Film Micro LED

Olw’obwetaavu bw’ebintu eby’okwolesa eby’obulungi obw’amaanyi ennyo n’enkulaakulana mu tekinologiya wa LED ow’omugatte, akatale ka Micro LED aka firimu ennyimpi mu nsi yonna kategeke okukula okw’amaanyi. Ebitundu ebikulu ebifuuwa amafuta mu kugaziya kuno mulimu:

• Ebintu ebikozesebwa mu matu ebya AR/VR

• HUD z’emmotoka

• Ebintu eby’okwambala ebigezi

Okusinziira ku kwekenneenya kw’amakolero okwakakolebwa, emitendera gino gijja kwanguyiza okuteeka ssente n’okunoonyereza n’okukulaakulanya mu perovskite ne tekinologiya w’okwolesa ebikwatagana nabyo.

Okumaliriza: Omulembe Omupya ogwa Micro LED Displays

Enkulaakulana y’a90nm PeLED pikselieraga enkyukakyuka mu nkulaakulana ya tekinologiya ow’okwolesa. Ne:

• Obunene bwa pikseli obutabangawo (127,000 PPI) .

• Ebisale by’okukola bitono bw’ogeraageranya ne III-V Micro LEDs

• Obulung’amu obuwangaazi ku sayizi za nanoscale

Perovskite-based Micro LED displays ziri mu mbeera nnungi okukulembera ebbidde eriddako ery’obuyiiya — naddala mu AR/VR, ebyuma ebyambalibwa, n’ebirala eby’omulembe ebirabika.

Nga okunoonyereza bwe kugenda mu maaso n’obukodyo bw’okufulumya bwe bukula, PeLEDs mu bbanga ttono ziyinza okufuuka omutindo gw’okwolesebwa okw’amaanyi ennyo mu makolero gonna.
