OLED, daim ntawv siab tshaj ntawm LED, sawv cev rau cov organic teeb-emitting diode. Tsis zoo li LED, uas siv lub teeb rov qab los muab lub teeb rau pixels, OLED tso siab rau cov khoom siv organic ua los ntawm cov saw hlau hydrocarbon kom tawm lub teeb thaum sib cuag nrog hluav taws xob.

Muaj ntau qhov zoo rau txoj hauv kev no, tshwj xeeb tshaj yog muaj peev xwm rau txhua tus thiab txhua lub pixel los ua lub teeb ntawm lawv tus kheej, ua kom muaj qhov sib txawv siab tsis kawg, txhais tau tias cov xim dub tuaj yeem dub thiab dawb heev.

Qhov no yog qhov laj thawj tseem ceeb ntau thiab ntau cov khoom siv OLED cov ntxaij vab tshaus, suav nrog cov xov tooj smartphones, cov khoom siv siv tau zoo li smartwatches, TVs, ntsiav tshuaj, desktop thiab laptop saib, thiab cov koob yees duab digital. Ntawm cov khoom siv thiab lwm tus yog ob hom OLED cov lus uas tau tswj hwm ntau txoj hauv kev, hu ua active-matrix (AMOLED) thiab passive-matrix (PMOLED).

Yuav ua li cas OLED ua haujlwm

Ib qho screen OLED suav nrog ntau yam khoom. Nyob rau hauv cov qauv, hu ua lub substrate, yog ib tug cathode uas muab electrons, anode uas "rub" cov electrons, thiab ib tug nruab nrab (cov organic txheej) uas cais lawv.

Sab hauv nruab nrab txheej yog ob txheej ntxiv, ib qho yog lub luag haujlwm tsim lub teeb thiab lwm qhov txhawm rau ntes lub teeb.

Cov xim ntawm lub teeb uas pom ntawm OLED zaub cuam tshuam los ntawm cov xim liab, ntsuab, thiab xiav txheej txuas nrog rau lub substrate. Thaum cov xim yuav tsum yog xim dub, lub pixel tuaj yeem muab tua kom ntseeg tau tias tsis muaj lub teeb tsim rau lub pixel ntawd.

Txoj kev no los tsim cov xim dub yog qhov txawv ntawm qhov siv nrog LED. Thaum lub pixel dub yuav tsum tau teem rau dub ntawm ib qho screen LED, lub pixel shutter kaw tab sis lub backlight tseem emitting lub teeb, txhais tau tias nws yeej tsis heev mus rau tag nrho txoj kev tsaus.

OLED Pros

Thaum piv rau LED thiab lwm yam khoom siv thev naus laus zis, OLED muab cov txiaj ntsig no:

  • Zog txuag vim lub teeb rov qab tsis tau siv. Tsis tas li ntawd, thaum siv cov xim dub, cov pixels tshwj xeeb tsis xav tau lub zog tag nrho, txuag zog ntxiv.
  • Tus nqi refresh yog nrawm dua vim tsis siv pixel shutters.
  • Nrog cov khoom tsawg dua, cov zaub, thiab yog li tag nrho cov cuab yeej tuaj yeem nyob nyias thiab hnav.
  • Dub xim yog xim dub tiag tiag vim cov pixels tuaj yeem raug kaw tag nrho thiab tsis muaj teeb pom kev zoo nyob tom qab uas muab lub teeb ci ntsa iab hauv cheeb tsam ntawd. Qhov no tso cai rau qhov sib piv ntawm qhov sib txawv siab heev (piv txwv li, cov xim dawb tshaj plaws tshaj qhov tsaus nti dub).
  • Txhawb nqa lub kaum sab xis uas tsis muaj xim ntau npaum li LED.
  • Qhov tsis muaj cov txheej txheem ntau dhau tso cai rau cov duab nkhaus thiab khoov tau.

OLED Cons

Txawm li cas los xij, tseem muaj qhov tsis zoo rau OLED cov lus:

  • Vim ib feem ntawm cov zaub yog cov organic, OLEDs qhia cov xim degradation nyob rau lub sijhawm, uas cuam tshuam rau tag nrho lub vijtsam ci thiab xim sib npaug. Qhov no tau dhau los zuj zus nrog lub sijhawm txij li cov khoom xav tau los ua kom cov tawv nqaij tawg sai dua li cov liab thiab ntsuab.
  • OLED cov ntxaij vab tshaus yog kim ua, tsawg kawg piv rau cov thev naus laus zis qub.
  • Ob leeg OLED thiab LED qhia txog kev tshuaj ntsuam hlawv-hauv yog tias cov pixels tshwj xeeb siv rau lub sijhawm ntev, tab sis cov txiaj ntsig zoo dua ntawm OLEDs. Txawm li cas los xij, cov nyhuv no yog ib feem txiav txim los ntawm tus lej ntawm pixels ib nti.

Cov Lus Qhia Ntxiv ntawm OLED

Tsis yog txhua lub OLED cov ntxaij vab tshaus yog tib yam; qee cov khoom siv siv ib hom OLED vaj huam sib luag vim lawv muaj kev siv tshwj xeeb.

Piv txwv li, lub xov tooj smartphone uas xav tau tus nqi siab dua rau HD cov duab thiab lwm cov ntsiab lus hloov pauv ib txwm siv yuav siv AMOLED zaub. Tsis tas li, vim tias cov lus qhia no siv cov yeeb yaj kiab nyias nyias los hloov cov pixels rau / tawm kom pom xim, lawv tuaj yeem ua pob tshab thiab hloov tau, hu ua OLEDs saj zawg zog (lossis FOLED).

Ntawm qhov tod tes, lub laij lej uas feem ntau qhia tib cov ntaub ntawv ntawm lub vijtsam rau lub sijhawm ntev dua li lub xov tooj, thiab qhov ntawd rov ua dua tshiab dua, tuaj yeem siv cov thev naus laus zis uas muab lub zog rau qee qhov chaw ntawm zaj duab xis kom txog thaum nws rov ua dua tshiab., zoo li PMOLED, qhov twg txhua kab ntawm cov zaub yog tswj los ntawm txhua pixel.

Qee lwm yam khoom siv uas siv OLED cov lus los ntawm cov tuam txhab tsim cov xov tooj smartphones thiab smartwatches, xws li Samsung, Google, Apple, thiab Cov Khoom Tseem Ceeb; cov koob yees duab digital xws li Sony, Panasonic, Nikon, thiab Fujifilm; ntsiav tshuaj los ntawm Lenovo, HP, Samsung, thiab Dell; laptops xws li Alienware, HP, thiab Apple; saib ntawm Oxygen, Sony, thiab Dell; thiab TV los ntawm cov tuam txhab xws li Toshiba, Panasonic, Bank & Olufsen, Sony, thiab Loewe. Txawm tias qee lub tsheb xov tooj cua thiab teeb siv OLED thev naus laus zis.

Dab tsi cov zaub yog tsim los ntawm tsis tas yuav piav txog nws qhov kev daws teeb meem. Hauv lwm lo lus, koj tsis tuaj yeem paub qhov kev daws teeb meem ntawm lub vijtsam (4K, HD, thiab lwm yam) vim tias koj paub tias nws yog OLED (lossis Super AMOLED, LCD, LED, CRT, thiab lwm yam).

QLED yog ib lo lus zoo sib xws uas Samsung siv los piav txog lub vaj huam sib luag uas LEDs sib tsoo nrog txheej ntawm quantum dots kom lub vijtsam teeb nyob rau hauv ntau xim. Nws sawv cev rau quantum-dot teeb-emitting diode.
