Cov duab tso saib ntawm LED siv lub teeb hluav taws xob hluav taws xob los tso saib cov duab hloov pauv ntawm cov teeb liab digital.Daim npav video siab JMC-LED tau tshwm sim, uas yog ua raws li 64-ntsis cov duab accelerator siv rau ntawm PCI tsheb npav, ua kom muaj kev sib koom ua ke nrog VGA thiab kev ua haujlwm video, tso cai rau cov ntaub ntawv video tso rau saum VGA cov ntaub ntawv, txhim kho kev sib raug zoo tsis txaus. .Txais yuav ib tug puv npo mus kom ze rau kev daws teeb meem, cov duab yees duab ua tiav tag nrho lub kaum sab xis daws teeb meem los txhim kho kev daws teeb meem, tshem tawm ntug qhov muag plooj teeb meem, thiab tuaj yeem scaled thiab txav tau txhua lub sijhawm, teb rau qhov sib txawv playback xav tau raws sijhawm.Sib cais cov xim liab, ntsuab, thiab xiav zoo txhawm rau txhim kho cov xim tiag tiag ntawm cov duab hluav taws xob.
Cov duab tiag tiag xim luam tawm
Feem ntau, kev sib xyaw ua ke ntawm cov xim liab, ntsuab, thiab xiav yuav tsum txaus siab rau qhov sib piv ntawm lub teeb ci uas zoo li 3: 6: 1.Cov duab liab yog qhov rhiab heev, yog li liab yuav tsum tau muab sib npaug sib npaug hauv cov duab spatial.Vim qhov sib txawv ntawm lub teeb siv ntawm peb xim, qhov kev daws teeb meem uas tsis yog linear curves nthuav tawm hauv tib neeg txoj kev pom kev kuj txawv.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum siv lub teeb dawb nrog cov teeb pom kev sib txawv los kho cov teeb pom kev sab nraud ntawm lub TV.Tib neeg lub peev xwm los paub qhov txawv xim txawv ntawm tus kheej thiab ib puag ncig sib txawv, thiab kev kho xim yuav tsum tau ua raws li qee lub hom phiaj ntsuas, xws li.
(1) Siv 660nm lub teeb liab, 525nm lub teeb ntsuab, thiab 470nm xiav lub teeb raws li qhov yooj yim wavelengths.
(2) Raws li qhov tseeb teeb pom kev zoo, siv 4 los yog ntau dua units uas tshaj lub teeb dawb rau kev sib piv.
(3) Qib grayscale yog 256.
(4) LED pixels yuav tsum tau ua cov ntaub ntawv pov thawj tsis-linear.Peb thawj xim piping tuaj yeem tswj tau los ntawm kev sib xyaw ua ke ntawm cov khoom siv kho vajtse thiab kev ua si rov qab software.
Brightness tswj digital zaub hloov dua siab tshiab
Siv tus maub los tswj lub teeb pom kev ntawm pixels, ua rau lawv ywj siab ntawm tus tsav tsheb.Thaum nthuav tawm cov yeeb yaj kiab xim, nws yog qhov tsim nyog los tswj qhov ci ntsa iab thiab xim ntawm txhua pixel thiab synchronize cov haujlwm scanning hauv lub sijhawm teev tseg.Txawm li cas los xij,loj LED hluav taws xob tso saibmuaj kaum tawm txhiab tus pixels, uas ua rau kom qhov nyuaj ntawm kev tswj thiab qhov nyuaj ntawm kev xa cov ntaub ntawv.Txawm li cas los xij, nws tsis yog qhov tseeb uas siv D / A los tswj txhua pixel hauv kev ua haujlwm.Nyob rau ntawm lub sijhawm no, yuav tsum muaj kev tswj hwm tshiab kom tau raws li qhov xav tau ntawm pixel system.Kev kho qhov sib piv zoo no tuaj yeem ua tiav kev tswj hwm ntawm pixel ci ntsa iab.Thaum siv lub hauv paus ntsiab lus no rau LED cov ntxaij vab tshaus hluav taws xob, cov teeb liab digital tuaj yeem hloov mus rau lub sijhawm teeb liab kom ua tiav D / A.
Kev tsim kho thiab khaws cov ntaub ntawv
Feem ntau siv kev nco ua ke tam sim no suav nrog kev sib xyaw pixel txoj kev thiab qib pixel me ntsis.Ntawm lawv, txoj kev dav hlau nruab nrab muaj qhov zoo tseem ceeb, txhim kho qhov pom kev pom zoo ntawmLED cov ntxaij vab tshaus.Los ntawm kev tsim kho lub voj voog los ntawm cov ntaub ntawv dav hlau me ntsis, RGB cov ntaub ntawv hloov dua siab tshiab tau ua tiav, qhov twg cov pixels sib txawv yog cov organically ua ke hauv tib qhov hnyav me ntsis, thiab cov qauv cia nyob ib sab yog siv rau cov ntaub ntawv khaws cia.
ISP rau Circuit Court tsim
Nrog rau qhov tshwm sim ntawm System Programmable Technology (ISP), cov neeg siv tuaj yeem rov kho qhov tsis txaus hauv lawv cov qauv tsim, tsim lawv tus kheej lub hom phiaj, cov tshuab, lossis cov laug cam, thiab ua tiav daim ntawv thov kev ua haujlwm ntawm software kev koom ua ke rau cov tsim qauv.Lub sijhawm no, kev sib xyaw ua ke ntawm cov tshuab digital thiab cov txheej txheem programmable thev naus laus zis tau coj cov teebmeem tshiab rau kev thov.Kev taw qhia thiab kev siv cov thev naus laus zis tshiab tau ua kom lub sijhawm tsim tau zoo, nthuav dav qhov txwv kev siv ntau yam ntawm cov khoom siv, ua kom yooj yim rau ntawm qhov chaw tu, thiab ua kom yooj yim rau kev ua tiav ntawm lub hom phiaj cov khoom siv.Thaum inputing logic rau hauv lub system software, lub hwj chim ntawm cov xaiv ntaus ntawv yuav raug ignored, thiab input Cheebtsam tuaj yeem xaiv tau dawb, lossis cov khoom siv virtual tuaj yeem xaiv rau kev hloov pauv tom qab cov tswv yim tiav.
Kev tiv thaiv
1. Hloov kev txiav txim:
Thaum qhib lub vijtsam: Qhib lub computer ua ntej, tom qab ntawd qhib lub vijtsam.
Thaum tua lub vijtsam: Tua lub vijtsam ua ntej, tom qab ntawd tua lub hwj chim.
(Tu tawm lub vijtsam zaub yam tsis tau tig nws yuav ua rau lub teeb ci ntawm lub vijtsam lub cev, thiab LED yuav hlawv lub teeb lub teeb, ua rau muaj qhov tshwm sim loj.).
Lub sijhawm ncua ntawm qhov qhib thiab kaw qhov screen yuav tsum ntau dua 5 feeb.
Tom qab nkag mus rau engineering tswj software, lub khoos phis tawj tuaj yeem qhib qhov screen thiab lub zog rau.
2. Tsis txhob tig rau ntawm lub vijtsam thaum nws yog dawb kiag li, vim tias lub kaw lus muaj qhov siab tshaj plaws.
3. Tsis txhob qhib lub vijtsam thaum nws poob kev tswj hwm, vim tias lub kaw lus nce siab ntawm nws qhov siab tshaj plaws.
Thaum lub vijtsam hluav taws xob hauv ib kab yog qhov ci heev, yuav tsum tau them nyiaj rau kev kaw lub vijtsam kom raws sijhawm.Hauv lub xeev no, nws tsis tsim nyog qhib lub vijtsam rau lub sijhawm ntev.
4. Covhluav taws xob hloovntawm lub vijtsam zaub feem ntau mus ncig, thiab lub vijtsam zaub yuav tsum tau kuaj xyuas lossis lub zog hloov pauv yuav tsum tau hloov raws sijhawm.
5. Tsis tu ncua xyuas qhov ruaj khov ntawm cov pob qij txha.Yog tias muaj qhov xoob, thov hloov kho raws sijhawm thiab rov ntxiv dag zog lossis hloov kho qhov raug ncua.
Thaum lub ambient kub siab heev los yog cov cua kub dissipation tej yam kev mob tsis zoo, LED teeb pom kev zoo yuav tsum tau ceev faj tsis txhob qhib lub screen rau lub sij hawm ntev.
