Raws li peb txhua tus paub, qhov me me-pitch LED zaub tam sim no yog ib qho ntawm cov khoom siv nrov tshaj plaws hauv tsev. Nws yog feem ntau siv nyob rau hauv high-end lub rooj sib tham chav, advanced exhibition halls, loj cov ntaub ntawv visualization platforms, hais kom ua thiab saib xyuas cov chaw, thiab lwm yam., nyob rau hauv thiaj li yuav qhia rau txhua leej txhua tus paub ntau ntxiv txog lub me-pitch LEDs. Zaub screen, ces Winbond Ying Optoelectronics yuav qhia rau koj txog cov technologies tseem ceeb ntawm me me-pitch coj zaub cov ntxaij vab tshaus thiab ib co kev ceev faj rau kev siv.

LED zaub ntawm cov duab siv lub teeb pom kev zoo hluav taws xob los tso saib qhov tshwm sim ntawm cov duab hloov dua siab tshiab ntawm cov teeb liab digital. Daim npav video tshwj xeeb JMC-LED tau los ua, thiab tsim kom muaj kev sib koom ua ke nrog VGA thiab kev ua haujlwm video raws li kev siv lub 64-ntsis cov duab nrawm ntawm lub npav PCI, kom cov ntaub ntawv yees duab tau tshaj ntawm VGA cov ntaub ntawv, thiab qhov tsis muaj kev sib raug zoo tau txhim kho. Siv cov txheej txheem puv npo los ntes cov kev daws teeb meem, cov duab yees duab tuaj yeem ua tiav lub kaum ntse ntse daws teeb meem thiab txhim kho cov txiaj ntsig daws teeb meem, tshem tawm cov teeb meem ntawm ntug plooj, thiab tuaj yeem zoom thiab txav cov duab txhua lub sijhawm, thiab tuaj yeem teb rau qhov sib txawv playback cov kev xav tau hauv lub sijhawm. Sib cais peb cov xim liab, ntsuab thiab xiav, thiab txhim kho cov xim tiag tiag ntawm cov duab hluav taws xob.
Cov duab tiag tiag xim luam tawm
Nyob rau hauv ib txwm muaj xwm txheej, peb cov xim sib txuas ntawm liab, ntsuab thiab xiav yuav tsum txaus siab rau qhov sib piv ntawm lub teeb ci mus rau 3: 6: 1; cov duab liab rhiab heev yog muaj zog, yog li cov liab nyob rau hauv qhov chaw tso saib yuav tsum tau sib npaug zos; vim hais tias lub teeb siv ntawm peb xim sib txawv, qhov kev daws teeb meem uas tsis yog linear nkhaus nthuav tawm los ntawm tib neeg kev pom kev pom kuj txawv. Yog li ntawd, nws yog ib qho tsim nyog yuav tau coj kom zoo dua ntawm lub teeb dawb ntawm lub teeb sib txawv los kho lub teeb sab hauv ntawm lub TV; Cov xim daws teeb meem muaj peev xwm sib txawv vim qhov sib txawv ntawm tus kheej thiab ib puag ncig sib txawv, thiab kev tsim cov xim yuav tsum tau ua raws li qee lub hom phiaj ntsuas, xws li:
(1) Muab qhov yooj yim wavelength ntawm 660nm lub teeb liab, 525nm lub teeb ntsuab, thiab 470nm xiav lub teeb.
(2) Raws li qhov teeb meem tiag tiag ntawm lub teeb siv, siv 4 lub raj lossis ntau dua 4 lub teeb dawb rau kev sib txuam.
(3) Grey nplai yog 256 qib.
(4) LED pixels yuav tsum tau ua tiav nrog cov ntawv tsis-linear proofreading. Qhov peb-xim piping tuaj yeem tswj tau los ntawm kev koom tes ntawm cov khoom siv kho vajtse thiab cov khoom siv rov ua dua tshiab. [4]
Brightness tswj D / T conversion
Tus maub los yog siv los tswj lub teeb emission ntawm pixels los txhawb kev ywj pheej ntawm kev tsav tsheb. Thaum cov yeeb yaj kiab xim yuav tsum tau nthuav tawm, qhov ci ntsa iab thiab xim ntawm txhua pixel yuav tsum tau tswj kom zoo, thiab kev ua haujlwm scanning yuav tsum ua kom tiav synchronously nyob rau hauv ib lub sij hawm. Tab sis qhov loj-scale LED hluav taws xob zaub screen muaj ntau txhiab pixels, uas ua rau kom cov kev tswj tsis yooj yim thiab nyuaj ntawm cov ntaub ntawv xa mus. Txawm li cas los xij, nws tsis muaj tseeb los siv D / A los tswj txhua pixel hauv kev ua haujlwm tiag tiag. Lub sijhawm no, yuav tsum muaj lub tswv yim tswj hwm tshiab kom tau raws li qhov xav tau ntawm pixel system. Raws li kev tsom xam ntawm cov ntsiab lus pom, qhov ci ntsa iab / tawm qhov sib piv ntawm pixel cov ntsiab lus yog lub hauv paus tseem ceeb rau tib neeg los tshuaj xyuas qhov nruab nrab qhov ci, thiab kev hloov kho tau zoo ntawm qhov piv no tuaj yeem ua tiav kev tswj hwm ntawm pixel brightness. Thaum lub hauv paus ntsiab lus no tau siv rau hauv lub vijtsam LED hluav taws xob, lub teeb liab digital tuaj yeem hloov mus rau lub sijhawm teeb liab, thiab kev hloov pauv tau zoo ntawm D / A tuaj yeem ua tiav.
Kev tsim kho thiab khaws cov ntaub ntawv
Tam sim no, txoj kev sib koom ua ke pixel thiab txoj kev tiaj tus pixel yog hom kev nco ua ke. Ntawm lawv, txoj kev dav hlau me ntsis muaj qhov pom tseeb zoo dua, uas ua kom zoo dua qhov zoo tshaj plaws cov nyhuv ntawm LED npo. Lub Circuit Court yog reconstructed los ntawm me ntsis-dav hlau cov ntaub ntawv, RGB cov ntaub ntawv yog hloov dua siab tshiab, txawv pixels nyob rau hauv tib lub luj me ntsis yog organically ua ke, thiab cov nyob ib sab cia qauv yog siv rau cov ntaub ntawv cia.
ISP hauv logic Circuit Court tsim
Nrog rau qhov tshwm sim ntawm System Programmable Technology (ISP), cov neeg siv tuaj yeem rov kho qhov tsis zoo hauv kev tsim thiab tsim lawv tus kheej lub hom phiaj, cov tshuab lossis cov rooj sib tham hauv Circuit Court, thiab paub txog tus tsim daim ntawv thov kev ua haujlwm ntawm kev sib koom ua ke software. Lub sijhawm no, cov tshuab digital thiab cov txheej txheem programmable thev naus laus zis Kev sib xyaw ua ke coj cov teebmeem tshiab rau daim ntawv thov. Kev taw qhia thiab siv cov thev naus laus zis tshiab ua tau zoo txo lub sijhawm tsim, nthuav dav siv cov khoom siv tsawg, ua kom yooj yim ntawm kev saib xyuas ntawm qhov chaw, thiab ua kom yooj yim rau kev ua tiav ntawm lub hom phiaj cov khoom siv. Thaum lub kaw lus software yog inputting logic, lub hwj chim ntawm cov xaiv ntaus ntawv yuav raug ignored, thiab cov input tivthaiv tuaj yeem xaiv ntawm lub siab nyiam, lossis cov khoom siv virtual tuaj yeem xaiv tau, thiab kev hloov pauv tuaj yeem ua tiav tom qab kev tawm tswv yim tiav.

Thaum tig ntawm qhov screen: qhib thawj zaug, tom qab ntawd tig rau ntawm qhov screen.
Thaum tua lub vijtsam: tua lub vijtsam ua ntej, tom qab ntawd tua.
(Tua lub khoos phis tawj ua ntej yam tsis tas yuav kaw lub vijtsam, nws yuav ua rau lub vijtsam lub cev pom qhov ci ntsa iab, LED yuav hlawv lub teeb raj, thiab qhov tshwm sim yuav loj heev.)
2. Lub sijhawm ntawm kev hloov cov ntxaij vab tshaus yuav tsum ntau dua 5 feeb.
3. Tom qab lub khoos phis tawj nkag mus rau engineering tswj software, lub vijtsam tuaj yeem qhib.
4. Tsis txhob tig lub vijtsam hauv lub xeev lub vijtsam dawb kiag li, vim tias qhov cuam tshuam tam sim no ntawm lub kaw lus yog qhov loj tshaj plaws nyob rau lub sijhawm no.
5. Tsis txhob tig lub vijtsam nyob rau hauv lub xeev tsis tswj, vim hais tias lub inrush tam sim no ntawm lub system yog qhov loj tshaj plaws nyob rau lub sij hawm no.
6. Thaum muaj kab ci ntsa iab heev hauv ib feem ntawm cov khoom siv hluav taws xob, koj yuav tsum tua lub vijtsam hauv lub sijhawm. Nws tsis pom zoo kom qhib lub vijtsam rau lub sijhawm ntev hauv lub xeev no.
7. Lub hwj chim hloov ntawm lub vijtsam zaub feem ntau mus ncig, thiab lub vijtsam lub cev yuav tsum tau kuaj xyuas lossis hloov lub hwj chim hloov lub sijhawm.
8. Tsis tu ncua xyuas qhov ruaj khov ntawm cov hooks. Yog tias muaj qhov xoob, xyuam xim rau kev hloov kho raws sijhawm, rov ntxiv dag zog lossis hloov kho cov khoom dai.
9. Thaum lub ambient kub siab heev los yog cov cua kub dissipation tej yam kev mob tsis zoo, lub teeb pom kev zoo LED yuav tsum tau ceev faj tsis txhob tig rau lub screen ntev.
