Iterambere muri Micro LED Yerekana: Pixel ntoya ku Isi kuri 90nm gusa

Mu ntera nini yo kwerekana ikoranabuhanga ryerekana, abashakashatsi bo muri kaminuza ya Zhejiang bashyize ahagaragara pigiseli ntoya ya LED ku isi - ipima gusaNanometero 90 (nm)- gushiraho igipimo gishya mugukemura no gukora neza ibisekuruza bizaza.

Bayobowe na Porofeseri David Di na Porofeseri Baodan Zhao, itsinda ry’ubushakashatsi ryashyize ahagaragara ibyo babonye muriKameremunsi y'umutwe"Kugabanya LED- na nano-perovskite LED."Akazi kabo gatangiza ultra-high-resolution LED array ishoboye kugeraho127,000 pigiseli kuri santimetero (PPI)- imyanzuro ihanitse yigeze kwandikwa muri tekinoroji ya LED.

Impamvu Iterambere Ryingenzi

Gakondo ya III-V ya semiconductor ishingiye kuri Micro LED yerekana ihura nimbogamizi zikomeye:

• Igiciro kinini cyo gukora

• Kugabanuka neza gukabije iyo bipimye munsi ya microni 10

Igisubizo gishya? LEDs ya Perovskite (PeLEDs), itanga ibyiza byinshi byingenzi:

• Ibiciro byo kubyaza umusaruro

• Imikorere myiza kurwego rwa nanoscale

• Imikorere ya kwant yo hanze (EQE) ya 20-30%, ugereranije na OLEDs

• Igihe kirekire cyo gukora cyegereye OLED ibipimo

Ubu bushya bufungura umuryango wimikorere ihanitse, ihendutse yerekanwe mbere itagerwaho hamwe na tekinoroji ya Micro LED isanzwe.

Udushya twihishe inyuma ya Pixel

Intandaro yibi byagezweho ni tekinike yo guhimba udushya izwi nkauburyo bwo guhuza amakuru. Uburyo bukoresha igikoresho cyiziritse hamwe na windows ishushanyije kugirango wirinde guhita ugaragara ibikoresho bya perovskite kuri electrode, bigabanya cyane gutakaza ingufu zidafite imirasire.

Nkigisubizo, PeLEDs ikomeza gukora neza ndetse no kuri ultra-nto nini - intambwe yingenzi kubikorwa bizaza-bikemurwa.

Kugereranya Imikorere: PeLED vs Micro LED gakondo

PeLEDs irusha Micro LEDs gakondo muburyo bwo gupima no gukora neza ku munzani ntoya, bigatuma iba abakandida beza kubijyanye na tekinoroji ikurikira.

Prototype Ifatika-Matrix Micro PeLED Yerekana

Iri tsinda kandi ryerekanye prototype ikora ya micro-PeLED ikora-yerekana ibicuruzwa byifashishwa mu bucuruzi bworoheje bwa firime (TFT) - byerekana ko ifite imbaraga mu bikorwa bifatika kandi bifatika.

Imanza zishobora gukoreshwa zirimo:

• Ukuri kwagutse (AR) nukuri kwukuri (VR)- Retina-urwego rusobanutse neza na ultra-high PPI

• Kwerekana- Umucyo woroshye kandi ukoresha imbaraga

• Ikirahure cyubwenge & Head-Up Yerekana (HUDs)- Umucyo mwinshi hamwe no gukoresha ingufu nke

Inzitizi n'umuhanda uri imbere

Nubwo hari intambwe imaze guterwa, ibibazo byinshi biracyahari mbere yuko PeLEDs igera ku musaruro rusange:

1. Ubuzima bwose hamwe no gushikama: Mugihe ubu PeLEDs yegera OLED imeze nkigihe cyo kubaho, haracyakenewe kunonosorwa mubikorwa byoherejwe mubucuruzi.

2. Ubunini: Guhindura kuva muri laboratoire ya prototypes kugera mubikorwa binini bizakenera guhanga udushya nko gucapa inkjet no gutunganya umuzingo.

3. Irushanwa: Micro OLED na kwant dot-yazamuye tekinoroji ya Micro LED nayo iratera imbere byihuse.

Nyamara, pigiseli itigeze ibaho ya PeLEDs ibaha umwanya wihariye muri niche, amasoko akomeye.

Inganda ziteganijwe: Gukura muri Thin-Film Micro LED

Bitewe no gukenera ultra-high-resolution yerekana no gutera imbere mu buhanga bwa LED, isoko rya Micro LED ku isi ryiteguye kuzamuka cyane. Inzego zingenzi zongerera ubu bwiyongere harimo:

• Umutwe wa AR / VR

• Imodoka HUDs

• Imyenda yubwenge

Dukurikije isesengura ry’inganda ziherutse, iyi nzira izihutisha ishoramari na R&D muri perovskite hamwe n’ikoranabuhanga ryerekana.

Umwanzuro: Igihe gishya kuri Micro LED Yerekana

Iterambere rya a90nm pigiseliIkimenyetso gihinduka muguhindagurika kwikoranabuhanga ryerekana. Hamwe na:

• Ubucucike bwa pigiseli butigeze bubaho (127,000 PPI)

• Amafaranga yo gukora make ugereranije na III-V Micro LED

• Imikorere irambye kubunini bwa nanoscale

Perovskite ishingiye kuri Micro LED yerekanwe ihagaze neza kugirango iyobore umurongo utaha wo guhanga udushya - cyane cyane muri AR / VR, ibikoresho byambarwa, nibindi bikoresho byohejuru byerekana amashusho.

Mugihe ubushakashatsi bukomeje hamwe nubuhanga bwo gukora bukuze, PeLEDs irashobora guhinduka igipimo cyerekana ultra-high-definition yerekanwe mu nganda.
