Qulqulka qiimaha alaabta semiconductor-ka ayaa ka dhigay bandhigyo LED midab buuxa ah oo la heli karo oo ku baahsan qaybaha kala duwan. Goobaha dibadda,muraayadaha LEDwaxay xoojiyeen booskooda sida dhexdhexaadiyaha bandhiga elektaroonigga ah ee waaweyn ee lama huraanka ah, taas oo ay ugu wacan tahay muujintooda iftiinka leh, waxtarka tamarta, iyo isdhexgalka aan cillad lahayn. Pixels-yada dibadda ee muraayadahaan midabka buuxa ee bannaanka waxaa loogu talagalay baakado laambad gaar ah, iyadoo pixel kasta uu leeyahay saddex tubbo LED ah oo midabyo kala duwan leh: buluug, casaan, iyo cagaar.
Jaantuska qaab-dhismeedka iyo curinta Pixel:
Pixel kasta oo ku yaal bannaanka midabka buuxa ee shaashadda LED wuxuu ka kooban yahay afar tubo oo LED ah: laba casaan, mid cagaar saafi ah, iyo mid buluug saafi ah. Nidaamkani wuxuu u oggolaanayaa abuurista midabyo kala duwan oo midab leh iyadoo la isku darayo midabada asaasiga ah.
Saamiga Iswaafajinta Midabka:
Saamiga dhalaalka ee casaanka, cagaarka, iyo buluugga LED-yada ayaa muhiim u ah soo saarista midabka saxda ah. Saamiga caadiga ah ee 3:6:1 ayaa inta badan la isticmaalaa, laakiin hagaajinta software ayaa la samayn karaa iyadoo lagu salaynayo dhalaalka dhabta ah ee bandhigga si loo gaaro dheelitirka midabka ugu fiican.
Cufnaanta Pixel:
Cufnaanta pixels ee bandhigga waxaa lagu tilmaamaa qiimaha 'P' (tusaale, P40, P31.25), kaas oo tilmaamaya masaafada u dhaxaysa xarumaha pixels ku xiga ee millimitir. Qiimayaasha 'P' ee sare waxay muujinayaan kala dheeraynta pixel-ka weyn iyo xallinta hoose, halka qiyamka 'P' hoose ay muujinayaan xallin sare. Doorashada cufnaanta pixel waxay kuxirantahay fogaanta daawashada iyo tayada sawirka la rabo.
Habka Wadista:
Bandhigyada LED midabka buuxa ee dibadda waxay caadi ahaan isticmaalaan wadista joogtada ah ee hadda jirta, taas oo hubinaysa dhalaalka deggan. Wadadu waxay noqon kartaa mid taagan ama mid firfircoon. Wadista firfircoonidu waxay yaraynaysaa cufnaanta wareegga iyo kharashyada iyada oo la caawinayo daadinta kulaylka iyo waxtarka tamarta, laakiin waxay keeni kartaa iftiin yar oo yaraada.
Pixels dhabta ah vs. Pixels Virtual:
pixels dhabta ah waxay si toos ah ugu siman yihiin tuubooyinka LED-ka ee shaashadda, halka pixels-ka-muuqaalka ah ay wadaagaan tuubooyinka LED-ga oo leh pixels ku xiga. Farsamaynta pixel Virtual waxay si wax ku ool ah u labanlaaban kartaa xallinta bandhigga sawirada firfircoon iyadoo ka faa'iidaysanaysa mabda'a haynta aragga. Si kastaba ha ahaatee, tignoolajiyadani waxtar uma laha sawirada taagan.
Tixgelinta Xulashada:
Markaad dooranayso amuuqaal buuxa oo LED ah, waa muhiim in la tixgeliyo halabuurka dhibcaha pixel ee ku salaysan dhibcaha pixel-ka. Tani waxay hubinaysaa in bandhiggu uu buuxin doono tayada sawirka la rabo iyo shuruudaha xallinta.
Xulashada bandhiga LED midabka buuxa ee dibadda waxa ay ku lug leedahay dheeli tirnaanta u dhaxaysa cufnaanta pixel, habka wadista, iyo isticmaalka pixels-ka dhabta ah ama farsamada, kuwaas oo dhamaantood gacan ka geysta waxqabadka bandhigga, qiimaha, iyo hufnaanta tamarta.
