Raws li thaj chaw tso saib ntawm LED cov khoom me me ua rau loj dua thiab loj dua, cov phiaj xwm ntawm kaum ntawm square metres tsis tshua muaj. Lub cev kev daws teeb meem ntawm LED cov lus qhia zoo li ntau dua 1920 × 1200, uas yog, txhua qhov loj-loj LED zaub muaj ntau yam Nws yog tsim los ntawm ntau qhov chaw ua haujlwm ywj pheej uas tau tsav los ntawm ib tus tswj hwm LED. Rau kev siv splicer, nws tsuas yog yuav tsum tau muab ob peb DVI tso zis interfaces sib xws rau cov lej ntawm LED tswj, thiab splice thiab tso saib tag nrho LED npo. Nyob rau hauv daim ntawv thov ntawm splicers nyob rau hauv me me-pitch LED qhia, ob peb yam tseem ceeb technologies yog tsim nyog mloog.
Me me pitch LED zaub
Lub teeb liab tso zis synchronization
Multi-channel DVI teeb liab tso zis ntawm lub splicer yuav tsum muaj teeb meem ntawm cov teeb liab synchronization. Thaum lub teeb liab unsynchronized tso zis rau LED zaub, daim duab tearing tshwm sim yuav tshwm sim ntawm qhov chaw splicing, uas yog tshwj xeeb tshaj yog pom tseeb thaum ua si high-ceev tsiv dluab. Yuav ua li cas los xyuas kom meej lub synchronization ntawm cov teeb liab tso zis tau dhau los ua tus yuam sij rau kev ntsuas qhov kev vam meej lossis tsis ua haujlwm ntawm kev sib txuas.
Graphics ua algorithm
Peb paub tias cov duab taw tes rau-taw tes tso saib cov nyhuv yog qhov zoo tshaj plaws. Tom qab cov duab txo qis, yog tias tsuas yog siv cov duab kos duab zoo tib yam lossis siv FPGA cov duab ua cov algorithms, cov npoo ntawm cov duab yuav tshwm jagged, thiab txawm tias pixels yuav ploj lawm. Lub brightness kuj yuav txo. High-end duab ua chips lossis FPGA systems siv cov duab ua haujlwm nyuaj yuav ua kom pom cov nyhuv ntawm cov duab txo mus rau qhov kawg. Yog li ntawd, ib tug zoo graphics ua algorithm yog ib tug tseem ceeb technology rau splicers siv rau me me-pitch LED zaub.

Tsis yog tus qauv daws teeb meem tso zis
Qhov me me-pitch LED zaub yog tsim los ntawm cov matrix ntawm cov khoom siv ntawm tib cov lus qhia. Qhov loj thiab lub cev daws teeb meem ntawm txhua chav tso saib yog tsau, tab sis lub spliced tag nrho cov vijtsam loj feem ntau tsis yog qhov kev daws teeb meem ntawm lub cev. Piv txwv li, qhov kev daws teeb meem ntawm chav tsev yog 128 × 96, uas tuaj yeem sau tsuas yog 1920 × 1152, tab sis tsis yog 1920 × 1080. Nyob rau hauv ib tug loj-scale splicing system, LED zaub cheeb tsam uas tau tsav los ntawm txhua LED maub los yuav tsis yog tus qauv daws teeb meem. Lub sijhawm no, nws yog ib qho tseem ceeb uas lub splicer muaj qhov kev daws teeb meem tsis zoo, uas tuaj yeem pab peb sai sai nrhiav qhov tsim nyog. Txoj kev splicing tuaj yeem faib cov peev txheej tsim nyog thiab txuag tau tus lej ntawm LED tswj thiab cov khoom siv sib kis.
