Tus qauv thiab cov yam ntxwv ntawm OLED display screen

Apr 07, 2018

OLED zaub yog daim ntawv thov kev siv tshuab ua OEL. Hauv yav dhau los tau ntau tshaj 10 xyoo, ntau cov kev tshawb fawb tau muab tso rau hauv kev tshawb kawm thiab kev tsim kho ntawm OLED technology. Cov qauv ntawm OLED zaub thiab OLED tso tawm tshuab tau ntau dua thiab paub tab. Tam sim no, OLED qhia txog kev ua si hauv neeg lub neej txhua hnub. Raws li cov ntaub ntawv qhia txog OLED, tshooj lus no luv luv soj ntsuam cov qauv thiab cov yam ntxwv ntawm cov duab OLED.


Yuav kom piav qhia txog cov qauv ntawm cov duab OLED, peb tuaj yeem piv rau txhua tus OLED cell rau lub hamburger, thiab cov khoom siv luminous yog cov zaub qhwv hauv nruab nrab. Txhua yam OLED cov khoom tso tawm yuav tswj tau los ua peb yam xim ntawm lub teeb. OLED, zoo ib yam li LCD, muaj qhov sib txawv ntawm kev ua ub no thiab kev ua haujlwm. Hauv kev siv hom passive, cov chaw xaiv los ntawm kab thiab kem chaw nyob yog pom kev. Nyob rau hauv lub hom phiaj, muaj ib zaj duab xis transistor (TFT) tom qab chav OLED, thiab lub teeb-emitting unit lit nyob hauv TFT tsav. Tus nquag OLED txuag hluav taws xob, tab sis cov passive OLED qhia tau zoo dua.


Cov duab OLED ua los ntawm cov nram qab no:

Cov theem pib (pob tshab yas, iav, hlau ntawv ci) yog siv los txhawb tag nrho OLED hauv theem theem.


Anode (pob tshab) - anode yuav tshem tawm cov electrons (nce electron qhov) thaum tam sim no ntws los ntawm lub cuab yeej.


Organic txheej txheej txheej txheej yog tsim los ntawm cov organic molecules los yog cov organic polymers.


Cov txheej txheem txheej txheem yog tsim los ntawm organic yas molecules, uas thauj cov qhov ntawm anode. Polyaniline yuav siv tau ua cov polymer hluav taws xob ntawm OLED.


Cov emitting txheej txheem yog ua los ntawm cov organic yas molecules (txawv ntawm cov txheej txheem txheej txheem). Cov lwg me me xa tawm electrons ntawm cathode, thiab cov txheej txheem ntawm luminescence yog nyob rau theem no. Polyfluorene yuav siv tau ua ib qho hnyav hlau emulsion.


Lub cathode, uas yog pob tshab los sis opaque, nyob ntawm seb cov hom OLED. Thaum lub sij hawm tam sim no yog nyob rau hauv lub cuab yeej, lub cathode yuav txhaj cov tshuaj electrons mus rau hauv Circuit Court.


Nta ntawm cov duab screen OLED

OLED, lossis Organic Light Emitting Diode, kuj yog hu ua Organic Electroluminesence Display (OELD). Vim nws lub teeb thiab hluav taws xob txuag nta, cov khoom siv no tau siv dav hauv MP3 player txij li xyoo 2003, thiab rau DC thiab txawb xov tooj, uas muaj cov khoom digital, qhov screen OLED tau tshwm nyob rau hauv ib co exhibitions, thiab nws tsis tau tau ua ntawv thov rau cov ntaub ntawv sau npe tseeb. Tab sis OLED npo muaj ntau yam tsis zoo ntawm LCD, yog li ntawd nws tau raug nuj nqis los ntawm kev lag luam.


OLED yog ib qho khoom siv luminescent. Nws tsis xav tau cov phaj ntsa. Nyob rau tib lub sij hawm, nws muaj qhov dav dav, zoo nrig xim, ceev ceev ceev, xim yooj yim dua, yooj yim tsav Circuit Court, yooj yim los ua lag luam thiab tuaj yeem ua rau kev kho vaj huam sib luag. Nws muaj raws li lub hauv paus ntsiab lus ntawm lub teeb thiab luv luv thiab me me. Tsab ntawv teev npe yog qhov chaw muaj vaj huam sib luag me thiab nrab.


Teeb thaj tsam: muaj teeb pom kev zoo, pom qhov dav dav, ceev ceev ceev ceev, duab zoo, ci ntsa iab, nplua nuj xim thiab siab.


Cov haujlwm ua haujlwm: tsis tsav tsheb tsawg tsawg thiab tsis muaj zog, uas tuaj yeem ua rau lub hnub ci qis thiab cov kev sib txuas ua ke.


Ntau txoj kev tuaj yeem tsim: iav substrate yuav siv tau los ua kom tiav cov cheeb tsam ntawm cov vaj huam sib luag. Yog hais tias cov khoom siv tau yooj yim siv los ua cov tshuaj substrate, nws tuaj yeem ua kom pom cov duab folding. Vim tias OLED yog tag nrho cov khoom, tsis muaj lub tshuab nqus tsev, nws muaj cov yam ntxwv ntawm av qeeg ua hauj, tsis kub (-40) thiab ntxiv rau. Nws tseem ceeb heev rau kev siv tub rog, xws li cov khoom dav hlau ntawm cov cuab yeej niaj hnub xws li tsheb thauj khoom thiab dav hlau.


Cov cuab yeej technology hauv OLED yog txawv los ntawm cov qauv duab hauv LCD, tsis muaj teeb ci, siv cov khoom siv nyias cov txheej txheem thiab iav substrate. Thaum lub sij hawm tam sim no, cov khoom siv organic yuav ci. Tsis tas li ntawd, qhov screen screen OLED yuav ua kom sib zog thiab thinner, qhov pom qhov loj dua, thiab nws tuaj yeem txuag hluav taws xob.


Tam sim no, nyob rau hauv ob qhov OLED technology system, lub tshuab hluav taws xob tsis muaj molecular OLED yog tsim los ntawm Nyij Pooj, thiab OEL ntawm lub xov tooj PLEDLG txawb xov tooj yog qhov system, technology thiab patent yog ntsej muag los ntawm lub tuam txhab British technology CDT, thiab tseem muaj teeb meem nyob rau hauv cov xim ntawm cov khoom PLED. Qhov tsis muaj molecular OLED feem ntau yuav muaj xim.


Txawm li cas los xij, tus OLED ntau yuav hloov LCD xws li TFT, organic light-emitting display technology tseem muaj qee qhov tsis txaus, xws li lub neej luv luv thiab cov npo loj.


Los ntawm cov qauv thiab cov yam ntxwv ntawm cov duab OLED, peb tuaj yeem paub hais tias OLED cov khoom yog ib qho khoom siv-lub xeev uas muaj cov nplooj ntawv nyias muaj nyias, thiab tuaj yeem pom kev tom qab siv hluav taws xob. OLED tuaj yeem ua rau cov khoom siv hluav taws xob ua cov duab ci thiab cov duab ntxig ntxig, thiab nws lub hwj huam tau siv zog dua li cov xim LED.
