LED Screen Hardware Cheebtsam (Core Display Unit)
1. Hom:
Monochrome LED: Qhia tsuas yog ib qho xim (xws li liab, ntsuab, lossis xiav), feem ntau siv rau cov ntawv nyeem yooj yim lossis ntsuas.
Dual-xim LED: tuaj yeem tso saib ob xim (xws li liab + ntsuab), ua tiav cov xim nruab nrab xws li daj thiab txiv kab ntxwv los ntawm kev sib xyaw.
Tag nrho-xim LED: Muaj xim liab, ntsuab, thiab xiav (RGB) LEDs, ua tiav tag nrho - xim zaub los ntawm kev sib txawv ci ntsa iab.
Ntim Cov Ntawv:
DIP (Dual In-kab Pob): Feem ntau siv nyob rau hauv cov theem pib, haum rau sab nraum zoov loj-pitch qhia, muaj zog waterproof thiab plua plav muaj peev xwm.
SMD (Surface Mount Device): Me me, siab ci, thiab dav pom lub kaum ntse ntse, haum rau sab hauv tsev me me - suab siab - cov lus txhais.
COB (Chip on Board): LED chips tau ntim ncaj qha rau ntawm PCB lub rooj tsavxwm, muab cov cua kub zoo thiab siab pixel ceev, haum rau ultra- siab- cov lus txhais.
2. Tsav Circuit Court (Controls LED On/Off)
Row Tsav Chip: Tswj cov scan ntawm LED kab, feem ntau yog siv cov chips tsav tsheb tam sim no (xws li MBI5026, TB62726) kom ruaj khov tam sim no.
Kem Tsav Chip: Tswj qhov ci ntawm LED kab, kho cov qib greyscale los ntawm PWM (Pulse Width Modulation) thev naus laus zis (xws li, 16-ntsis greyscale tuaj yeem tso saib 65536 xim).
Kev tswj fais fab: Muab qhov hluav taws xob ruaj khov rau LEDs thiab tsav tsheb chips, feem ntau siv cov khoom siv hluav taws xob hloov lossis cov khoom siv hluav taws xob tas li.
3. Tswj Daim Npav (Sib Ncauj Ua Haujlwm thiab Kev Xa Mus)
Xa Daim Npav: Tau txais cov teeb liab los ntawm lub computer lossis video qhov chaw (xws li HDMI, DVI, SDI), thiab hloov lawv mus rau hauv hom pom tau los ntawm LED zaub.
Tau Txais Daim Npav: Nruab rau sab nraum qab ntawm lub vijtsam zaub, nws tau txais cov cim los ntawm daim npav xa thiab tsav cov hlaws LED sib xws hauv thaj chaw tso saib.
Network Communication Module: Txhawb Wi-Fi, 4G/5G, lossis Ethernet rau kev tswj chaw taws teeb thiab cov ntsiab lus hloov tshiab.
4. Cov qauv ncej thiab cov cua txias
Txee / Ncej: Ua los ntawm aluminium alloy lossis ntawv hlau, tiv thaiv cov khoom siv sab hauv thiab kho LED modules.
Cooling Design: Txo qhov kub thiab txias los ntawm cov dab dej kub, kiv cua, los yog ntuj convection kom ua haujlwm ruaj khov nyob rau lub sijhawm ntev.
Kev Tiv Thaiv Qib: Sab nraum zoov cov ntxaij vab tshaus yuav tsum tsis muaj dej tsis zoo (IP65 lossis siab dua), tsis muaj plua plav, thiab muaj peev xwm tiv thaiv xob laim.
5. Kev Siv Hluav Taws Xob thiab Hluav Taws Xob
Kev Siv Hluav Taws Xob: Muab lub zog DC ruaj khov (xws li 5V, 12V), uas yuav tsum ua kom tau raws li qhov xav tau ntawm lub zog tag nrho ntawm lub vijtsam. Cables: Nrog rau cov fais fab cables thiab cov teeb liab cables (xws li network cables thiab ribbon cables), lawv yuav tsum muaj peev xwm tiv thaiv - cuam tshuam.
