Cias muab tso, ib qho screen LED yog tsim los ntawm ob peb combinable zaub units (unit zaub boards los yog chav tsev zaub txee) uas tsim lub screen lub cev, ntxiv rau ib tug tsim nyog controllers (lub ntsiab tswj board los yog tswj system). Yog li ntawd, ntau yam kev qhia tshwj xeeb ntawm cov khoom lag luam (lossis chav tsev) ua ke nrog cov tswj hwm siv cov thev naus laus zis sib txawv tuaj yeem tsim ntau hom LED cov ntxaij vab tshaus kom ua tau raws li qhov xav tau ntawm qhov chaw sib txawv thiab cov khoom xav tau.
Cov ncauj lus kom ntxaws ntawm ib qho screen LED qhia cov khoom hauv qab no (kev siv lub vijtsam ntau dua synchronous video ua piv txwv):
I. Hlau ncej
Cov ntxaij vab tshaus sab hauv feem ntau muaj cov hlau txhawb nqa, nqa ntau lub rooj tsav xwm hauv Circuit Court xws li cov rooj sib tham thiab cov khoom siv hluav taws xob hloov. Lub thav duab sab nrauv siv aluminium alloy square tubes, lossis aluminium alloy clad stainless hlau, los yog ua los ntawm cov ntawv hlau sib xyaw.
Lub puab ncej ntawm sab nraum zoov cov ntxaij vab tshaus yog ib tug hlau waterproof box qauv. Cov txheej txheem sab nrauv, nyob ntawm qhov loj ntawm lub vijtsam thiab thauj khoom- cov kabmob muaj peev xwm, feem ntau yog ua los ntawm lub kaum sab xis steel lossis I- kab teeb, thiab cov thav duab sab nrauv tuaj yeem dai kom zoo nkauj nrog aluminium composite panels.
II. Tsos Unit
Qhov no yog qhov tseem ceeb ntawm lub vijtsam zaub, tsim los ntawm cov khoom siv luminous thiab tsav tsheb. Cov ntxaij vab tshaus sab hauv siv ntau yam kev qhia tshwj xeeb ntawm chav tsev zaub boards, thaum cov ntxaij vab tshaus sab nraum zoov siv chav tsev.
III. Scanning Control Board
Lub rooj tsav xwm Circuit Court no muaj nuj nqi yog cov ntaub ntawv buffering, tsim ntau yam scanning signals thiab lub luag hauj lwm voj voog greyscale tswj cov cim.
IV. Switching Power Supply
Hloov 220V AC lub zog rau hauv ntau qhov DC voltages muab lub zog rau ntau lub voj voog.
V. Twisted -Pair Transmission Cable
Cov ntaub ntawv tso saib thiab ntau yam kev tswj cov teeb liab tsim los ntawm lub ntsiab tswj system yog kis los ntawm lub computer mus rau lub vijtsam lub cev ntawm twisted -pair cables.
VI. Main Control System
Buffers, ua qhov hloov dua siab tshiab, thiab rov teeb tsa cov tswv yim RGB digital video signals, thiab tsim ntau yam kev tswj cov cim.
VII. Dedicated Display Card thiab Multimedia Card
Ntxiv nrog rau cov haujlwm tseem ceeb ntawm daim npav computer, nws tseem tso tawm cov cim RGB digital thiab kab rov tav, ntsug, thiab blanking teeb liab mus rau lub ntsiab tswj. Ntxiv nrog rau cov haujlwm saum toj no, daim npav multimedia kuj tseem tuaj yeem hloov cov tswv yim analog video teeb liab rau hauv cov teeb liab RGB (ie, video capture).
VIII. Computer thiab Peripherals
IX. Lwm cov ntaub ntawv
TV, DVD / VCD player, video koob yees duab, thiab hloov matrices, thiab lwm yam.
