Dabtsi Quantum Dots?

Dabtsi Quantum Dots?

Apr 04, 2018

Thawj qhov yuav ua kom meej yog tias lub QDs uas twb muaj lawm yog qhov tseem ceeb tib yam li LCD TV. Ib qhov tseem ceeb tshaj plaws ntawm cov TV hauv TV yog lub luminescence ntawm pixels, yog li nws tsis xav tau qhov teeb ci ntsa iab. QD TV thiab LCD TV tseem xav tau kev txhawb zog. Yog li nws muaj qhov zoo thiab qhov tsis zoo li LCD TV hauv qee qhov chaw.

  

Tab sis thaum peb tham txog cov xim ntawm kev taw qhia, qhov txawv yog tuaj. Feem ntau LCD TV backlight siv lub teeb dawb, tab sis QDs TV siv xiav lub teeb. Txawm lawv txhua tus siv cov xim xiav, LCD LCD TV yuav los siv tseem muaj xim florescent ua kom pom teeb pom kev dawb. Quantum dot TV siv xiav qhov muag, thaum cov quantum dots tuaj yeem ntsuab lossis xim liab. Thaum xiav lub teeb ci ntsa iab ntawm cov quantum dots, nws yuav tawm xws li lub zog muaj zog.


Interestingly, cov xim ntawm quantum dots yog txiav txim los ntawm lawv cov me me. Cov qoob loo quantum uas tawm hauv lub teeb liab yog loj tshaj cov ntawm 50 atoms, thiab cov quantum dots uas emit ntsuab lub teeb muaj me dua 30 atoms. Cov no yog cov xim tiag tiag, thiab qhov purity yog siab heev. Yog li, piv nrog cov TV LCD txwm, lawv pom ntau cov yeeb yuj thiab cov duab tiag tiag. Hauv kev sib piv, lub teeb dawb siv hauv LCD TV yuav tuaj yeem mus rau qhov kev tshuaj ntsuam vim nws qhov dav spectrum, thiab nws yuav tsis tau txais xim thiab tag nrho xim.


Qhov zoo thiab qhov tsis zoo ntawm cov quantum dots

Qhov zoo ntawm quantum dots yog, raws li tau hais los saum toj no, ua ntej ntawm tag nrho, nws cov lus tseeb yog tseeb. Cov xim ntawm lub teeb uas tawm los ntawm quantum dot yog ze rau nws qhov loj, yog li nws muaj peev xwm ua tau ntau dua ntawm qhov kev hloov, uas txhais tau hais tias cov xim yuav ntshiab ntau dua thiab meej tshaj, thiab dawb zoo dua huv.


Lwm tus taw tes yog tias quantum dot TV muaj ntau dua ci ntsa iab. Nws kuj tau hais ua ntej tias lub pob liab liab thiab lub teeb ntsuab tawm ntawm quantum dots yog cov tsiv heev thaum lawv muaj teeb meem ntawm xiav lub teeb. John Workman, chief marketing officer ntawm QD Vision, piav qhia tias xiav yog qhov tseem ceeb tshaj thiab feem ntau qhov nquag feem ntawm spectrum, uas muaj zog dua liab thiab ntsuab. Nws yuav zoo dua qub kom txo cov teeb ci zog mus rau lub zog qis zog thiab tsim liab thiab ntsuab. Txwv tsis pub, nws yuav nyuaj li thawb lub pob zeb saum lub roob.


Tam sim no muaj qee mobile siv cov quantum dot tshuab, xws li Amazon lub Kindle Fire HDX 7 thiab HDX 8.9, nrog rau ASUS tus ZenBook NX500. Quantum dot technology ntau dua hauv kev ntsuam xyuas. Yog li, piv nrog lub dav LCD npo, nws kuj yuav ntau zog npaum.


Tsis tas li ntawd, rau cov neeg muag khoom, zoo li kev ua haujlwm ntawm quantum dot technology thiab cov cuab yeej LCD technology kuj txhais tau hais tias cov kab ntau tshaj plaws tsis tas yuav txiav tawm qhov kev xyaum ua kom tiav, uas yog qhov tseem ceeb rau cov nqi txuag.


Peb tau cia li hais tias QDs npo kuj yog ib qho screen siab, ces tom kawg muaj qee yam tsis muaj tseeb. Tus qub tseem yuav muaj qee yam teeb meem, tshwj xeeb tshaj yog cov leak txuas. Koj yuav pom tias xiav lub teeb uas ntub rau ntawm ntug kev siv cov tshuab ntaus quantum dot, uas yog ib qho laj thawj rau cov khoom siv uas xaim dawb teeb.


Dab tsi txog OLED?

Txawm hais tias quantum dot technology tau ntau zog dua cov tshuaj LCD tshuab, nws yuav tsis yeej nrog OLED. Peb tau hais tias OLED muaj cov yam ntxwv ntawm pixel tus kheej luminescence, yog li thaum pixels muab tua, peb yuav saib tau cov blackest dub. Qhov kev sib txawv ntawm no tseem yuav tsum tau rov qab tshuab.


Nyob rau hauv cov nqe lus ntawm lub zog noj, OLED nkawd muaj ib tug ntau zoo dua. Nws tseem yog lub cwj pwm ntawm pixel tus kheej luminescence, uas yog ntau lub zog txuag tshaj li qhov khoom xav backlighting txhua lub sij hawm, uas yog tseem muaj teeb meem ntawm chav kawm.


Ib qho kev lag luam txawv txav ntseeg tias quantum dot technology yuav tsum tsis txhob raug saib raws li lub tshuab tshiab, tab sis kev txhim kho. Nws yog nce raws li cov cuab yeej technology LCD, thiab tus nqi thiab kev siv nyuaj nyuaj yuav tsum zoo tshaj qhov TV uas twb muaj lawm. Txawm li cas los xij, kev xav tau los ntawm kev muaj zog thiab muaj zog dua, kev kawm ntawm OLED technology tsis tuaj yeem ntsuas.


Tam sim no Samsung tau qhib ib txoj kev tshiab, thiab tau tsim QLED technology. QLED technology yog ib daim ntawv thov kev tshaj lij ntawm cov quantum dots. Nws ncaj qha ua quantum dots lub teeb los ntawm hluav taws xob tsav, thiab ces ua cov duab los ntawm cov xim xim. Nyob rau hauv no txoj kev, ob qho tib si lub kua siv lead ua kua thiab lub teeb vaj tse teeb meem tsis xav tau. Ntawm no pom, QLED zoo ib yam li OLED, uas yog qhov kev xav ntawm kev tshawb fawb.
