Tus Optoelectronic tau daim ntawv RGB puv xim MicroLED zaub

Apr 17, 2018

Nyob rau ntawm 2018 International Display Technology Conference (ICDT 2018), Taiwan thaj av ua lag luam Playnitride qhia Micro LED lus, ua rau cov neeg tuaj saib xyuas kev sib tw, nrog tag nrho 3 xim, dawb, ntsuab thiab tag nrho xim.


Lub 0.89 "display siv nyob rau hauv watches, PPI yog li 169, thiab siv cov xim xiav LED chos Phosphor xim, ntxiv rau 0.8 'saib, PPI nce mus rau 230, thiab monochrome schemes nrog ntsuab chips ntsuab.Thaum kawg, xim 0.89 'cov lus tso tawm kom pom, siv RGB LED nti ua ke, txog 103 PPI Lub neej yav tom ntej neptunium txuas ntxiv los txhim kho technology, kom pom LED ntawm Micro coj mus muag tom ntej.


  

Kuj rau cov khw muag khoom ntawm cov tsav tsheb thiab cov khoom thaij duab (Jasper Display), lub Micro LED zaub nrog Silicon raws li cov kev teev lus qhia. Cov duab technology tau tsim rau 0.7 ', thiab cov zaub loj yuav ncav cuag 4K rooj. Txawm hais tias nws yog monochromatic zaub, qhov tsawg tshaj plaws Pixel loj tuaj yeem sab nrauv 3.74 um, nrog cov khoom siv loj.

Leti's Francois Templier hais tias Micro LED yog siv rau ib qho siv los siv hauv AR VR thiab lwm yam qhia txog kev hnav kom tau raws li siab thiab tsis pom cov cheeb tsam yuav tsum muaj, ces LED nti loj thiab LED Pitch yuav me. Qhov siab tshaj plaws ntawm Cov Tsiaj Ntoo Tawg Bumping yog li 15 lub hli, thiab yog tias Micro Tube yog ua rau GaN Array nyob Wafer, Micro Tube yuav muab tso rau hauv kev sib txuas nrog cov khoom cog rau sab nraud. Luv LED tsev tuam tsev. Tam sim no, Leti tau siv cov cuab yeej no rau monochromatic lus, Pixel Pitch yog hais txog 10 m, thiab kev daws teeb meem yog 873 x 500 Pixels.


San ib optoelectronic Xu Chenke tus lwm thawj tswj hwm hais tias Micro LED muaj kev ntsuam xyuas dua dua lwm cov kev tso saib xws li LCD, LCOS, DLP thiab OLED. Nyob rau hauv sib piv rau cov ntawv thov OLED pom, Micro LED zoo dua nyob rau hauv kev ci ntsa iab thiab kev ntseeg siab, thiab siv tau nrog soft substrates mus rau cov lus muag flexible, yog li peb qho kev xaiv ntawm Opt-Micro LED tsim thiab muaj kev nthuav dav.

Tam sim no, San ib optoelectronic tau tsim ib RGB puv xim Micro LED zaub, uas cov sab nraud lwm tus quantum efficiency (EQE) ntawm RGB chips yog kwv yees li 18%, 30%, 60%, thiab yav tom ntej tseem nce siab. Tsis tas li ntawd, Xu Chen Department kuj hais tias peb qho kev xaiv ntawm tus kheej kuj tseem tuaj yeem muab cov ntaub ntawv xa mus, Muab nyiaj, thiab lwm yam kev pabcuam, xws li cov kab rov tav lossis ntsug electrode LED nti. Qhov loj ntawm Chip Chip nti ntawm kab rov tav electrode yog txog 30 ~ 100 m, thiab qhov ntsug electrode nti ncav cuag 10 ~ 100 m.


  

Xib fwb Liu Jimei hais tias Micro LED ua qhov me me thiab me me rau yav tom ntej li cov chips LED ua qhov me thiab me. Ntxiv nrog rau cov kev siv technology hloov, qhov zoo ntawm LED tus nti raug tsim nyog yuav tsum ruaj khov thiab paub tab kom txhim kho kom ntau li ntau thiab txo cov nqi. Raws li deb raws li kev tsim vaj tse tsim kev txhawj xeeb, peb yuav siv sij hawm tsim kev tsim qauv rau kev loj hlob raws li lub ntsiab qhov kev nrhiav kom tau tus tshaj plaws Micro LED tsav tsheb.


Tam sim no, qhov tsawg kawg nkaus Micro Display tsim los ntawm xibfwb Liu Jimei ncav cuag 0.19 ', 1700 PPI, uas yog monochromatic zaub tswvyim. Daim ntawv thov ntawm miniaturized quantum dots yuav tsis yuav tsis tuaj, li Professor Liu 's pab neeg kuj siv technology ntawm quantum dots ua tiav xim. Tam sim no, cov RGB quantum dots yog tusyees coated ntawm Micro Display los ntawm kev siv number case-jet printing. Cov lus yog li 3.6 hli (L) x 3.6 hli (W), thiab qhov kev daws teeb meem yog li ntawm 40 x 40 pixels.


  

Xwb Yang Xuyong of Shanghai Univer tau qhia tias kev tsim QD daim ntawv thov ntawm LED tsuas yog siv nyiaj thiab lub neej xwb. QD khoom nqi tsis pheej yig, yog li cov ntaub ntawv siv tau yooj yim muab xa mus rau cov neeg tau txais kev pab, uas ua rau txo kev lag luam competitiveness. Tsis tas li ntawd, lub neej ntev txog 100 ~ 1000 teev, yog li xibfwb Yang Xuyong sim ntxiv cov hlau oxide zaj duab xis mus rau QD ntxiv kom ruaj ntseg ntawm QD thiab nce nws lub neej. Cov kev xeem tau zoo, kev pab lub neej muaj peev xwm ncav cuag 16000 xuab moos (NITS 100), yuav ua rau daim ntawv thov QD yav tom ntej hauv LED ntawm ib kauj ruam ntxiv.
