Xim Gamut Kho Ntawm LED Zaub

Xim Gamut Kho Ntawm LED Zaub

Nov 16, 2017

LEDs muaj teeb meem muaj xws li ci ci thiab xim xim, uas yuav txo tau cov duab zoo ntawm LED zaub. Daim ntawv no muab ib txoj kev los kho cov xim ntawm gamut LED. Cov txheej txheem yuav daws tau cov teeb meem teeb meem, thaum kho qhov xim ntawm cov roj teeb ntawm LED, Cov ntawv no tsim tau ib lub qauv lej ntawm LED cov zaub mov, ntsuas cov phiaj xim gamut ntawm LED zaub, Tom qab ntawd, txoj kev kho nrog cov phiaj xim gamut raws li LED lus 'cwm tswv yim gamut yog tswvcuab, Tas, dawb tshuav hauv xim gamut kho lus yog tswvcuab txhim kho xim xim coordinates ntawm cov xim, Experimental tau tsom tias hom no yuav kho cov xim gamut ntawm LED zaub rau phiaj xim gamut tseeb.


LED zaub yog ua los ntawm cov duab pixels npaj hauv array, uas muaj qhov zoo ntawm kev ci ntsa iab, dav xim gamut thiab kev cia siab heev. Tau dav siv nyob rau hauv ntau qhov chaw ntawm daim duab zaub, thaum tus tsav tam sim no, kub hloov; LED luminous siv thiab wavelength yuav hloov kom cov xim gamut tsis ruaj khov, yog li ntawd, grey qib tswj system ntawm cov xim xim tag nrho xim tsuas yog ib qho xim los ntawm kev siv hom kev xauv paj pulation PWM, los ntawm kev tswj cov mem tes dav tswj lub teeb lub sij hawm LED, paub qhov grey theem zaub, thaum lub teeb liab, ntsuab thiab xiav LED pom tau tias yog peb xim LED qhov screen. Ua ke nrog peb thawj xim nrog ntau hom grey ua rau tag nrho cov xim uas tuaj yeem tso tawm kom pom los ntawm LED cov yeeb yaj duab, thiab cov ntaub ntawv xim ntawm cov yeeb yam ntawm LED.

  

Lub teeb luminance ntawm LED muaj ib qho kev txiav txim siab. Nyob rau hauv cov txheej txheem uas twb muaj lawm, txawm tias yog ib qho khoom siv ntawm cov khoom nti khoom siv roj, qhov sib txawv ntawm txoj kev muaj peev xwm yuav raug tswj tsis pub dhau 30%, thiab qhov pauv ntawm qhov pwg muaj peev xwm tswj tau hauv 510nm. Kev kam rau siab ntawm tib neeg lub qhov muag kom muaj nuj nqis sib txawv yog 5%, thiab qhov ua siab dav dav ntawm lub ntsiab wavelength tis qhov txawv yog 12nm. Yog li ntawd, thaum lub vijtsam LED qhia txog tib theem txho, muaj qhov sib txawv ntawm qhov ci ntsa iab thiab chromaticity ntawm cov pixels. Thaum qhov txawv txav ib qhov twg, qhov kev xav ntawm qhov muag ntawm tib neeg ntawm qhov zoo ntawm LED zaub yuav poob siab. Tsis tas li ntawd, nrog rau cov theem kev lag luam thiab kev ua lag luam xav tau kev ua lag luam, kev ncaj ncees, kev siab ncaj thiab zoo li ntawd rau ntawm cov kev xav tau qhov muag thov, tau npaj cov kev thov brand-new rau cov xim muaj peev xwm. Thiaj li yuav ua rau cov teeb meem tsis sib xws ntawm LED thiab tau txais ntau daim ntawv teev cov kev cai, qhov ci ntsa iab thiab chrominance kev kho qhov system tau siv rau kev tswj qhov ntsuas LED. Tam sim no, ci ntsa iab kho tshuab tau dav dav siv hauv tshuab kev tsim qauv, tau lawm kom daws tau cov teeb meem zoo dua

Uneven degree tau dav siv nyob rau hauv LED screen uas yuav tsum muaj cov zaub zoo siab, xws li theem tom qab, kev lag luam kev lag luam thiab lwm yam. Txawm li cas los xij, txoj kev tshawb nrhiav ntawm LED gamut yog npaj rau cov cheeb tsam ntawm kev muaj siab ncaj thiab gamut ntau. Kev hloov xim tshuab yog ib txhia tuam txhab lag luam thiab kev tshawb nrhiav thiab kev loj hlob hauv tsev thiab sab nraud nyob rau hauv txoj kev tshawb no, tau nce ib co kev sib tw. Nws tau raug siv nyob hauv ib co duab ntxiab. Cov xim uas twb muaj lawm siv cov ntaub ntawv ntsuas raws li cov khoom ua haujlwm. Feem ntau ntawm lawv tsom rau kev tso saib tib xim thawj, txo cov xim txawv ntawm cov duab pixels. Nws tsis tas yuav tsum muaj xim xim ntawm cov xim liab, xim ntsuab thiab xiav xim ntawm LED qhov screen, thiab ob peb lub tshuab kho nrog peb cov xim thawj xim kom muaj xim muaj peev xwm kho cov peev xwm. Peb. Nws tsis yooj yim los txiav txim siab saib cov lus qhia ntawm cov duab LED ntawm tib lub sij hawm tsis tau xav txog qhov tseeb ntawm peb thawj xim thiab qhov tseeb ntawm daim teb xim xim dawb. Kev kho qhov kev ua lej yog raws li ob tug qub, thaum kho qhov peb thawj xim xim haujlwm thiab lub teb dawb xim xim ntawm cov LED, uas yog lub hauv paus rau tus qauv ntawm LED pom cov nyhuv thiab kev lees paub ntawm cov kev ntseeg siab.
