Hauv txoj kev tshawb fawb tshiab tshiab, cov kws tshawb fawb ntawm University of Minnesota, Twin Cities, 3D luam tawm lub teeb hloov pauv tau yooj yim organic-emitting diode (OLED) zaub siv lub tshuab luam ntawv kev cai, Antarctic Xyooj tau kawm thaum Lub Ib Hlis 11, 2021. Cov kev tshawb fawb Cov txiaj ntsig tau raug luam tawm hauv phau ntawv xov xwm SCIENCE ADVANCES. Qhov no yuav tsum tau txo qis tus nqi ntawm OLED cov lus qhia.
OLED zaub thev naus laus zis siv cov txheej txheem ntawm cov khoom siv organic los hloov hluav taws xob rau hauv lub teeb. OLEDs tuaj yeem ua tau yooj yim rau siv hauv cov khoom siv loj xws li TV cov ntxaij vab tshaus thiab cov saib, nrog rau hauv cov khoom siv hluav taws xob xws li smartphones. OLED cov lus tau txais txiaj ntsig thoob plaws vim lawv lub teeb yuag, txuag hluav taws xob, nyias thiab yoog raws, qhov pom dav dav thiab qhov sib piv siab.
Txawm li cas los xij, OLED cov duab zoo li yuav kim vim tias lawv feem ntau yuav tsum tau ua nyob rau hauv loj, kim, thiab ultra- cov chaw huv. Txog qhov kawg, cov kws tshawb fawb ntawm University of Minnesota, Twin Cities npaj yuav tsim ib txoj hauv kev pheej yig dua los ua OLED cov duab.
"OLED displays are typically produced in large, expensive, ultra-clean manufacturing plants," said Michael McAlpine, the Kuhrmeyer Family Chair Professor in the Department of Mechanical Engineering at the University of Minnesota and senior author of the study. "We wanted to see if we could do it on our desktop 3D printers. Basically condensing all of that and printing out an OLED display, the printer is custom made and costs about the same as a Tesla Model S."
Yog li ntawd, cov kws tshawb fawb tau sim siv 3D luam ntawv los tsim OLED cov lus, kho lub tshuab luam ntawv 3D rau lub hom phiaj no, thiab sim ob hom kev luam ntawv sib txawv, thiab thaum kawg tau ua tiav tiav luam tawm 1.5-inch sab nrog 64 64 pixels. OLED zaub, thiab txhua pixel ua haujlwm zoo. Qhov kev tshawb pom yav tom ntej tuaj yeem ua rau kev tsim cov khoom siv OLED uas tsis tshua muaj nqi uas txhua tus tuaj yeem tsim hauv tsev siv lub tshuab luam ntawv 3D, tsis yog tsim los ntawm cov kws tshaj lij hauv cov chaw tsim khoom kim microfabrication.
3D tag nrho- luam tawm qauv ntawm lub teeb hloov pauv tau yooj yim ntawm cov organic teeb pom kev zoo-emitting diode (OLED) zaub yog li 1.5 ntiv tes ntawm txhua sab thiab muaj 64 pixels. Txhua pixel ua haujlwm thiab pom lub teeb. 3D- cov ntawv luam tawm kuj hloov pauv tau, uas tuaj yeem ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov, xws li cov khoom lag luam foldable.

Tsis tas li ntawd, cov kws tshawb fawb kuj tau ua 2, 000 bending tests ntawm OLED zaub, thiab cov zaub tseem ua haujlwm ib txwm, uas txhais tau hais tias nws yuav tsum tau siv rau hauv cov khoom siv OLED hloov tau hauv cov khoom siv hnav.
Cov kauj ruam tom ntej, cov kws tshawb fawb tau hais tias, yog luam tawm OLED zaub loj dua uas tseem yuav txhim kho ntxiv hauv kev daws teeb meem thiab ci ntsa iab.
Nws tau nkag siab tias OLED, tseem hu ua organic hluav taws xob laser zaub thiab cov teeb pom kev organic-emitting semiconductor, belongs rau tam sim no -hom organic teeb- emitting ntaus ntawv. Nws yog qhov tshwm sim ntawm luminescence tshwm sim los ntawm kev txhaj tshuaj thiab rov ua dua ntawm cov nqa khoom.
