Puas Muaj Qhov Sib Txawv ntawm QLED Thiab OLED?

Apr 24, 2018

Hauv qab no, OLED yog raws li lub hauv paus ntawm cov organic electroluminescence, thiab QLED yog raws li lub hauv paus ntawm cov qauv kev hloov hauv cov hlau (lossis photoluminescence). Txij li cov cim ntawm thermal stability thiab chemical stability ntawm cov ntaub ntawv inorganic feem ntau siab dua cov cov organic teeb meem, cov cim tseem ceeb ntawm QLED lub teeb qhov kev nyab xeeb thiab lub neej muaj zog dua OLED hauv kev tshawb xav, uas yog vim li cas qee cov neeg xav tias QLED lub cim ntxiv tom ntej no technology uas yog kev tsim nyog ntawm kev cia siab.


QLED yog lub LED uas yog luminescent los ntawm cov teeb meem tsis sib thooj, thiab OLED yog LED emitting los ntawm cov organic teeb meem. Q thiab O zoo li ua lawv txiv, thiab LED yog lawv niam. LED - Lub teeb Emitting Diode lub teeb emitting diode, uas muaj qhov zoo thiab tsis zoo ncej nyob rau ntawm qhov tam sim no los ntawm qhov zoo ncej mus rau qhov tsis zoo electrode, los ntawm cov khoom siv lub teeb nyob rau ntawm lub diode, qhov hluav taws xob tam sim no excites nws tso tawm lub teeb zog, peb pom nws - ci .

Txawm hais tias nws yog raws li lub ntsiab lus ntawm lub teeb emitting diodes, QLED npo thiab OLED npo yog cov zog zoo dua qhov ntsuas LED zoo tib yam saib raws li kev lag luam, pixel ceev, kev ua haujlwm xim, thiab kev tswj hluav taws xob. Qhov no yog vim hais tias cov tub ntxhais luminescent ntaus ntawm cov roj teeb yog ib qho khoom siv hluav taws xob cov khoom hluav taws xob ntawm electroluminescent nti, thiab cov txheej txheem raug tsim tau yooj yim.


  

Txawm tias tam sim no siab ntom LED zaub (qhov chaw me me LED) tsuas ua tau 0.7 hli taw tes nrawm, nrog rau iPhone7 xov tooj lub npo loj (138.3mm 67.1mm), qhov daws teeb meem tsuas yog 19795, ncaj qha mus txo rau hauv lub meter (kua, SONY yog ua hauj lwm los tsim lub Micro-LED tshuab nyuaj rau chij OLED, QLED, Cov kev lag luam yog nyob deb deb ntawm kev sib tham ntawm no.


Nyob rau hauv kev npaj ntawm QLED thiab OLED, cov khoom thiab cov cuab yeej muaj cov kev cai ntawm kev tshawb fawb txog kev tshawb fawb, yog li ntawd tsuas yog qee lub lag luam ntawm Yelemes, Nyij Pooj Teb, Kauslim Teb, uas tuaj yeem koom tau rau hauv cov khoom siv ntws los, ntawm yav tom ntej dub technology nyob rau hauv high school kev teeb meem, thiab kev tshwm sim yog yeej tsis "kev cob qhia". Tshaj.

Qhov tiag TV QLED yog ua raws li txoj cai ntawm electroluminescence ntawm inorganic quantum dot lub teeb emitting diodes (QDs), uas ua rau QLED cov khoom siv lub teeb emitting nquag, thiab qhia cov xim sib txawv los ntawm kev tswj cov kab txawv ntawm cov ntaub ntawv inorganic thiab particle loj li ntawm, yog li ras txog daim ntawv thov ntawm cov khoom siv ntawm daim duab.


Hauv cov txheej txheem ntawm OLED, vim cov organic molecules ntawm luminescent centre, feem ntau yog tsim los ntawm cov txheej txheem cov txheej txheem, uas yog, los ua cov txheej txheem luminescent ntawm kev kub siab rau hauv cov qauv me me, thiab tom qab ntawd kom rov soj ntsuam dua txoj haujlwm. Hom no yog xav tau heev rau qhov chaw, thiab txoj kev yog txoj thiab meej. Qhov tseem ceeb tshaj plaws yog hais tias nws yog qhov nyuaj heev kom tau raws li lub loj teev. Qhov kev xav tau ntawm qhov nti npo.


QLED luminescent center yog ib qho khoom nruab nrab ntawm nanocrystalline, uas muaj peev xwm ua tiav rau ntau hom kev daws teeb meem. Nws yog tau los npaj los ntawm kev daws. Ntawm qhov one hand, nws tuaj yeem txo qhov raug nqi, thiab ntawm qhov tod tes, nws tuaj yeem tawg los ntawm kev txwv ntawm kev tshuaj ntsuam.
