Teeb pom kev zoo Paub Basics 4 OLED

Teeb pom kev zoo Paub Basics 4 OLED
OLED yog lub npe luv ntawm Organic Light-Emitting Diode hauv lus Askiv. Ntawd yog, cov organic electroluminescent diode tseem hu ua organic EL. Nws belongs rau organic teeb-emitting cov ntaub ntawv, thiab feem ntau hu ua organic teeb-emitting semiconductor T.

Organic electroluminescence yog txheeb ze rau inorganic electroluminescence. Ib leeg-crystal EL tau tshawb pom thaum ntxov li xyoo 1923, thiab inorganic EL tau tsim nyob rau xyoo 1936. Qee cov ntaub ntawv inorganic emit lub teeb thaum muaj hluav taws xob siv thoob plaws lawv. Organic EL tau tshawb fawb thiab saib xyuas los ntawm tib neeg thaum ntxov li xyoo 1950. Lub teeb-emitting txoj cai ntawm organic EL zoo ib yam li cov LED, yog li nws tseem hu ua organic teeb-emitting diode, uas yog, OLED.

Lub hauv paus ntsiab lus ntawm OLED luminescence: zoo ib yam li lub hauv paus ntsiab lus ntawm LED luminescence, carrier qhov thiab electrons raug txhaj los ntawm anode thiab cathode raws, thiab cov cab kuj thiab electrons sib ntsib nyob rau hauv lub teeb-emitting txheej ntawm cov organic khoom, recombined los tsim excitons, thiab cov excitons lwj nyob rau hauv hluav taws xob Ib feem ntawm nws yog hloov dua siab tshiab rau hauv lub teeb, thiab ib feem rau hauv tshav kub thiab lwm yam zog. Qhov sib txawv ntawm OLED thiab LED yog qhov kev sib cuag ntawm cov khoom siv organic thiab cov electrode yog Schottky tiv tauj, thiab cov txheej txheem kev txhaj tshuaj yog tunneling txhaj tshuaj.

Nrog rau kev nce qib ntawm kev siv thev naus laus zis, kev sib sib zog nqus ntawm OLED kev tshawb fawb thiab kev txhim kho thiab kev ua tiav ntawm cov khoom siv thev naus laus zis, OLED tau maj mam siv rau hauv kev xyaum, thiab nws cov ntawv thov ntau dua thiab dav dua. Nws tau dhau los ua lub ntsiab lus kub hauv kev ua yeeb yam thiab teeb pom kev zoo niaj hnub no.

OLED keeb kwm kev loj hlob: Txawm hais tias keeb kwm ntawm OLED yog ntxov dua li ntawm LED [tsim nyob rau hauv 1962], thaum ntxov li 1953, manganese lucite lub teeb emission tau pom, tab sis tsis muaj kev vam meej loj hauv OLED rau lub sijhawm ntev tom qab ntawd. Green EL tau tsim thiab tsim los ntawm Pioneer hauv xyoo 1997, thiab tom qab ntawd OLED cov duab xim kuj tau tsim. Thiab Sony tau qhia nws thawj OLED TV hauv xyoo 2007. Tom qab ntawd qhov loj ntawm OLED TV tau loj thiab loj dua, thiab lub ntsiab lus tau nce siab dua. Nws yog sought tom qab los ntawm loj manufacturers. OLED teeb pom kev zoo tshuaj ntsuam cov khoom kuj tau tsim. Txawm li cas los xij, vim qhov kev txwv ntawm OLED lub teeb pom kev zoo thiab tus nqi siab, nws tsis tau siv ntau hauv kev teeb pom kev zoo tam sim no.

Qhov zoo ntawm OLED: Qhov laj thawj yog vim li cas nws thiaj nrhiav tom qab yog tias OLED cov khoom muaj ntau yam zoo. OLED muaj qhov zoo tshaj plaws nyob rau hauv ob qho tib si teeb pom kev zoo thiab cov zaub. OLED npo yog ultra-nyias, tsawg dua 1 hli tuab. Lub kaum sab xis saib yog dav, thiab tsis muaj teeb meem pom lub kaum ntse ntse tuag. khoom qauv. Teb ceev. Zoo tsis kub zoo. Tsawg zog siv. Ua tau yooj yim khoov. Lub spectrum yog ntau tiav. Vim qhov pom tseeb zoo ntawm OLED ua cov khoom siv, OLED cov khoom lag luam tau tsim sai heev nyob rau xyoo tas los no, xws li kev xa khoom ntawm OLED TVs, xov tooj ntawm tes, thiab cov lus qhia tau ua tiav kev loj hlob loj.

Hauv thaj chaw teeb pom kev zoo, cov txiaj ntsig saum toj no tseem muaj nyob. Piv txwv li, OLED cov khoom siv teeb pom kev zoo kuj tuaj yeem ua nyias li ntawv, muaj qhov pom tseeb siab, thiab tuaj yeem khoov thiab txiav arbitrarily. Tsis tas li ntawd, rau cov teeb pom kev loj hauv cheeb tsam, OLED lub teeb kuj zoo ib yam, thiab tsis tas yuav muaj ntau lub teeb pom kev zoo xws li cov ntawv qhia lub teeb kom ua rau lub teeb pom kev zoo. OLED muaj cua sov tsawg, tsis zoo li LED teeb pom kev zoo cov khoom uas muaj cov cua kub dissipation siab. Tab sis nyob rau theem no, vim hais tias cov thev naus laus zis ntawm OLED cov khoom siv rau cov teeb pom kev zoo tsis paub tab, qhov ci ntsa iab tsis txaus, thiab lub neej tsis zoo li cov LEDs, cov nqi tam sim no tseem tseem siab.

Txawm li cas los xij, tseem muaj ntau lub tuam txhab lag luam nqis peev hauv kev tshawb fawb thiab kev tsim kho thiab tsim cov khoom siv teeb pom kev zoo OLED, uas tau siv rau qee yam hauv qee qhov tshwj xeeb teeb pom kev zoo, xws li teeb pom kev hauv tsev, teeb pom kev kho mob thiab lwm yam. Nrog rau kev txhim kho ntawm OLED lub teeb pom kev zoo, kev txuas ntxiv ntawm lub neej, nce kev tsim khoom loj, txo tus nqi, thiab kev loj hlob ntawm cov txheej txheem tsim khoom, OLED cov khoom siv teeb pom kev zoo kuj yuav dhau los ua qhov sib txawv ntawm cov teeb pom kev zoo xws li cov khoom siv teeb pom kev zoo, thiab nkag mus rau cov khoom siv teeb pom kev zoo. tsev ntawm cov neeg zoo tib yam.
