Cov teeb pom kev zoo ntawm lub teeb-emitting diode (OLED) yog qhov nrov nrov dua. Lawv yog cov tseem ceeb hauv cov xov tooj ntawm tes, cov neeg tshaj tawm xov xwm, thiab cov xovtooj uas tsis tshua muaj me me. Tsis zoo li cov qauv LCDs, OLED pixels yog tsav los ntawm cov chaw tam sim no. Yuav kom nkag siab tias lub hwjchim ci ntsa iab ntawm OLED thiab qhov kev cuam tshuam licas, koj yuav tsum xub nkag siab lub tshuab kev qhia OLED thiab cov khoom siv fais fab. Tsab ntawv xov xwm no yuav qhia txog cov cuab yeej technology hauv OLED, thiab tshawb txog cov khoom siv hluav taws xob loj thiab cov kev daws teeb meem, nrog rau cov qauv siv hluav taws xob tshiab uas tsim los siv rau cov khoom siv hluav taws xob hauv OLED.

Backplane tshuab los tsim kom muaj kev yoojyim ntawm cov duab siab loj xim Matrix organic teeb-emitting diode (AMOLED) tso saib lub pob zeb loj nraub qaum, kev siv tom qab siv tus nquag hloov rau txhua lub pixel hloov. Cov kua siv lead ua kua (LC) zaub cov txheej txheem cawv (silicon) yog mature, muaj peev xwm muab tau tus nqi qis qis dua matrix npab, thiab siv tau rau OLED. Ntau lub tuam txhab tau tsim cov organic thin zaj duab xis transistor (OTFT) cov txheej txheem rov qab rau cov duab muag, thiab cov txheej txheem no kuj tseem siv tau rau hauv cov lus qhia OLED kom cov kev qhia txog cov xim tha xim. Ob tus qauv thiab mos qhov OLED yuav tsum muaj tib lub hwj chim thiab tsav tshuab. Kom nkag siab txog kev sib cuam tshuam ntawm OLED technology, functionality, thiab nws lub hwj chim, lub tshuab nws tus kheej yuav tsum tau ntsuas xyuas qhov tob. Lub OLED monitor yog lub tshuab pom pib lub tshuab xauv lub tshuab uas tshem tawm qhov xav tau kev nrig qaum. Cov khoom siv uas tau txais los ntawm OLED yog cov khoom siv rau cov khoom siv hluav taws xob. Cov cuab yeej hluav taws xob OLED yuav tsum muaj txoj kev tsav tsheb tam sim no. OLED muaj ib yam dab tsi zoo hluav taws xob rau cov qauv teeb emitting diode (LED), thiab qhov ci ntsa iab nyob ntawm LED tam sim no. Yog xav tau thiab tshem tawm ntawm OLED thiab tswj cov kev siv tam sim no, ib qho kev tswj xyuas hluav taws xob uas siv cov yeeb yaj kiab zaj duab xis transistor (TFT).

Lub hwj huam ceev tshaj plaws yuav ua tiav qhov siab tshaj plaws thiab cov roj teeb uas siv hluav taws xob, kev khiav hauj lwm ntawm qhov siab tshaj plaws nkaus nkaus xwb nyob rau hauv tag nrho cov kev thauj khoom tam sim no rau lub converter, ua kom lub sij hawm ntawm lub roj teeb tos ntev, qhov no yog qhov tshwj xeeb tshaj yog tseem ceeb rau OLED cov duab. Cov duab OLED siv zog tshaj plaws thaum nws tuaj yeem dawb dawb. Rau lwm cov duab xim, tam sim no tseem tsawg, vim tias tsuas yog yuav tsum muaj tag nrho cov xim liab, ntsuab, thiab xiav pixels yuav tsum tag nrho kaj. Piv txwv, ib tug 2.7 nti zaub yuav tsum 80mA tam sim no kom muaj tag nrho cov duab dawb, tab sis tsuas yog 5mA tseev tsim nyog los tso saib lwm cov icons los yog duab. Yog li ntawd, lub hwj huam hluav taws xob OLED yuav tsum tau muaj kev hloov siab rau txhua qhov dej ntsaws. Ua kom tiav qhov kev ua tau zoo no, kev siv hluav taws xob ntau hom kev tsim nyog yuav tsum ua kom txo tau qhov kev thauj mus los kom tsis txhob muaj qhov sib hloov ntawm cov khoom siv sib hloov. Vim tias nws yog los ntawm qhov ntsuas hluav taws xob (VCO), yog li EMI tuaj yeem ua tau kom tsawg, thiab yuav tswj tau qhov kev sib hloov ntawm qhov sib txawv ntawm qhov qis tshaj 40kHz, uas tuaj yeem tiv thaiv lub suab nrov los ntawm cov tswv yim los yog tso zis ua haujlwm capacitor ceramics. Qhov no yog qhov tshwj xeeb tshaj yog thaum siv cov khoom siv hauv txawb ntawv, thiab simplifies tsim cov txheej txheem.

Raws li cov yam ntxwv luminous, lub teeb dawb tsis yog lub hwj chim loj tshaj plaws, nws yog qhov ci ntsa luj los txiav txim siab txog kev siv fais fab. Xws li xim liab, xiav, ntsuab, ci ntsa iab yog 10, nrog rau kev ci ntsa iab yuav ua rau 30 tus nqi ci ntawm lub teeb dawb. Yog li ntawd, qhov tseem ceeb ntawm cov xim liab, xiav, thiab ntsuab tseem ceeb yog 3.3, thiab ib qho kev ntsuas dawb ntawm 10 yog muab coj los ua ke (theoretical value). Los ntawm LED los yog OLED, lub qhov muag pom tib qho kaj ci, thiab Blu ray siv zog tshaj plaws.
