Midabka iyo waxtarka iftiinka leh ee LED-yadu waxay la xiriiraan alaabta iyo hababka loo isticmaalo soo saaridooda. Cas, cagaar, iyo buluug ayaa ah kuwa ugu isticmaalka badan. Sababtoo ah bandhigyada LED waxay ku shaqeeyaan danab hooseeya (kaliya 5V), waxay si firfircoon u soo saari karaan iftiin leh dhalaal gaar ah oo lagu hagaajin karo danab (ama hadda), waxayna saameynayaan- u adkaysta, gariirka - u adkaysta, oo leh cimri dherer (100,000 saacadood), ma jiro qaab kale oo bandhig ah oo la tartami kara bandhigyada LED ee waaweyn{7}}qalabka bandhiga cabbirka.
Shaashadda soo bandhigta ee isku daraysa LED-yada cas iyo cagaarka ah sidii hal pixels waxa loo yaqaan shaashadda labajibbaaran{0}ama mid buuxda{1}; shaashada soo bandhigta oo isku daraysa LED-yada cas, cagaar, iyo buluuga ah sida hal pixel waxa loo yaqaan saddex{2}screen midab ama buuxa{3}}. Shaashadaha LED-ka ee gudaha waxay caadi ahaan leeyihiin cabbir pixels 2{9}}20 mm, inta badana isticmaala dhowr chips LED oo soo saara midabo kala duwan oo la isku dubariday. Shaashadaha LED-ka ee bannaanka waxay caadi ahaan leeyihiin cabbir pixels 8{12}}32 mm, iyadoo pixel kastaa ka kooban yahay dhowr LEDs monochrome ah. Alaabooyinka la dhammeeyay ee caadiga ah waxaa loo yaqaan tuubooyinka pixel; Tuubooyinka pixel dual-midab guud ahaan waxay ka kooban yihiin 2 casaan iyo 1 cagaaran LEDs, halka tuubooyinka saddex-midabka pixel ka kooban yahay 1 cas, 1 cagaaran, iyo 1 buluug LED.
Haddi loo isticmaalo LEDs si loo abuuro monochrome, dual{0}}midab, ama saddex midab{{1}screens, dhalaalka LED kasta oo ka kooban pixels waa in la hagaajin karo si loo muujiyo sawirka. Wanaajinta hagaajintan waxaa loo yaqaan heerka cabbirka cawliga ee shaashadda. Markasta oo uu sareeyo heerka cabbirka cawl, sawirka la soo bandhigay wuu sii jilicsan yahay, midabada ayaa sii badanaya, waana sii adkaanaysaa nidaamka xakamaynta bandhigga. Guud ahaan, sawir 256-heer ah oo cawl ah ayaa leh midab kala-guur oo aad u siman, halka sawirka midabka cawl ee 16-heer ah uu leeyahay xuduud kala-guurka midab aad u cad. Sidaa darteed, muraayadaha LED midabka hadda ayaa looga baahan yahay inay yeeshaan 256 ilaa 4096 heerar cawl.
Qalabka nalalka LED-ka ee loo isticmaalo bandhigyada waxay ku yimaadaan qaababka soo socda:
Laambadaha LED (ama hal laambadood): Guud ahaan waxay ka kooban yihiin hal jib oo LED ah, milicsi, bir anode ah, iyo cathode bir ah, oo ku dhex jira qolof resin epoxy leh oo leh iftiin-awood ururin Hal ama in ka badan (midabo kala duwan) hal nalal ayaa ka koobnaan kara pixel aasaasiga ah. Iftiinkooda sare awgeed, inta badan waxaa lagu isticmaalaa bandhigyada dibadda.
Qaybaha dhibicda LED-ka: Ka kooban dhowr chips oo ka samaysanaya matrix luminescent ah, oo ku duuban qolof resin epoxy gudaha qolof caag ah. Ku habboon wadiyaasha iskaanka safafka iyo tiirarka, si fudud u samaynaya bandhigyo cufnaanta sare-, oo inta badan lagu isticmaalo bandhigyada gudaha.
Dusha sare ee LED-yada (ama SMD LEDs) waa laydhyo ku jira xidhmo korka dulsaaran, oo ku haboon gudaha gudaha buuxa{0}}muusyada midabka, u oggolaanaya dayactirka hal dhibic{1} iyo si wax ku ool ah looga gudbo saamaynta mosaic.
