Malinga ndi malipoti aposachedwa ochokera ku South Korea media, Korea Photonics Technology Institute (KOPTI) yalengeza zakukula bwino kwaukadaulo wa Micro LED.Kugwira ntchito kwamkati kwa Micro LED kumatha kusungidwa mkati mwa 90%, mosasamala kanthu za kukula kwa chip kapena kachulukidwe kake ka jakisoni.

20μm Micro LED yokhotakhota yapano yamagetsi ndi chithunzi chotulutsa (chithunzi cha ngongole: KOPTI)

Tekinoloje iyi ya Micro LED idapangidwa pamodzi ndi gulu la Dr. Jong hyup Baek kuchokera ku Optical Semiconductor Display Department, gulu la ZOGAN Semi lotsogozedwa ndi Dr. Woong ryeol Ryu, ndi Pulofesa Jong ku Shim kuchokera ku Dipatimenti ya Nano-Optoelectronics ku yunivesite ya Hanyang.Chogulitsacho chimayang'ana vuto la kuchepa kwachangu kwa kuwala kwamagetsi mu ma Micro LED chifukwa cha kuchepa kwa kukula kwa chip komanso kuchuluka kwa ma jakisoni.

Zapezeka kuti ma LED ang'onoang'ono omwe ali pansi pa 20μm kukula kwake samangokhala ndi kuchepa kofulumira kwa mpweya wabwino komanso amawonetsa kutayika kwakukulu kosagwirizana ndi ma radiation mkati mwamtundu wapano (0.01A/cm² mpaka 1A/cm²) wofunikira pakuyendetsa ma panel owonetsera. .Pakadali pano, makampaniwa amachepetsa nkhaniyi pang'onopang'ono kudzera munjira zapa chip, koma sizimathetsa vutoli.

The internal quantum performance (IQE) ya 20μm ndi 10μm blue Micro LED imasiyanasiyana malinga ndi kachulukidwe kameneka.

KOPTI ikufotokoza kuti gulu lofufuzira lachepetsa zovuta mu epitaxial layer ndikuwongolera kuwala kotulutsa kuwala pokhazikitsa dongosolo latsopano.Dongosolo latsopanoli limapondereza kusinthasintha kwapang'onopang'ono kwa Micro LED pansi pa gawo lililonse lamagetsi lakunja kapena kapangidwe kake.Zotsatira zake, ngakhale ndi kukula kwakung'ono kwa Micro LED, mawonekedwe atsopanowa amachepetsa kwambiri kuwonongeka kopanda ma radiation pomwe akusunga bwino mpweya wabwino popanda kufunikira kwa njira zodutsa.

Gululi latsimikizira bwino kugwiritsa ntchito luso laukadaulo la Micro LED mu buluu, gallium nitride green, ndi zida zofiira.M'tsogolomu, teknolojiyi imakhala ndi kuthekera kopanga zowonetsera zamtundu wa gallium nitride Micro LED.
