Horumarinta tignoolajiyada LED-ka, iftiinka bandhigyada elektiroonigga ah ee LED ayaa sii kordhayay, cabbirkuna wuu sii yaraanayaa oo wuu sii yaraanayaa, taas oo muujinaysa in bandhigyo koronto oo badan oo LED ah oo gudaha ah ay noqon doonaan isbeddelka guud. Si kastaba ha noqotee, iyadoo ay ugu wacan tahay hagaajinta iftiinka LED-ka iyo cufnaanta pixel si loo xakameeyo shaashadda LED-ka iyo wadista waxay sidoo kale keentaa shuruudo sare oo cusub. Shaashada guud ee gudaha gudaha, hadda habka kontoroolka caadiga ah waxaa loo isticmaalaa safafka iyo tiirarka hab-hoosaadka, taas oo ah, sida caadiga ah loo tixraaco habka iskaanka, hadda, habka bandhiga elektaroonigga ah ee LED wuxuu leeyahay iskaan joogto ah iyo iskaanka firfircoon Laba nooc oo iskaan ah oo taagan ayaa loo qaybiyaa pixels-ka dhabta ah iyo kuwa aan caadiga ahayn, iskaanka firfircoon waxa kale oo loo qaybiyaa sawir dhab ah oo firfircoon iyo firfircooni firfircoon.
Muujinta elegtarooniga ah ee LED, tirada safafka oo shiday isla waqtigaas iyo saamiga tirada safafka ee aagga oo dhan, oo loo yaqaan habka iskaanka. Sawir-qaadista sidoo kale waxa loo qaybiyaa 1/2iskaan, 1/4iskaan, 1/8iskaan, 1/16iskaaniyo wixii la mid ah dhowr siyaabood oo wadista. Taasi waa in la yiraahdo, bandhiggu maaha mid isku mid ah darawalnimada, ka dibna goobaha kaadhka qaataha ayaa sidoo kale ka duwan. Haddii kaarka qaataha markii hore lagu isticmaalay shaashadda 1/4 ee iskaanka, oo hadda lagu isticmaalo shaashadda taagan, markaa bandhigga shaashadda wuxuu noqon doonaa 4 kasta oo saf oo iftiin leh. Kaarka qaadashada guud waa la dejin karaa, lagu xidhi karaa kaarka diritaanka, bandhiga, kumbuyuutarka iyo aaladaha kale ee waaweyn, waxaad geli kartaa software-ka ku habboon kombiyuutarka si aad u dejiso. Markaa halkan waa kan ugu horreeya ee soo bandhigaya qaabka sawirka elektiroonigga ah ee LED-ka iyo mabda'a.
- Habka iskaanka bandhiga elegtarooniga ah ee LED.
1. Scaning Dynamic: iskaanka firfircooni waa ka soo saarida darawalka IC ilaa pixel inta u dhaxaysa hirgelinta kontoroolka "point-to-column", wareegga xakamaynta iskaanka firfircoon ayaa loo baahan yahay, kharashkuna wuu ka hooseeyaa sawirka iskaanka, laakiin Saamaynta bandhiggu waa ka liidataa, luminta dhalaalka weyn.
2. Scaning Static: scanning static waa wax soo saarka ka darawalka IC in pixel u dhexeeya fulinta "point-to-point" gacanta ku, iskaanka static uma baahna wareegyada kontoroolka, kharashka ayaa ka sarreeya iskaanka firfircoon, laakiin Saamaynta bandhiggu waa wanaagsan tahay, xasillooni wanaagsan, lumis iftiin yar iyo wixii la mid ah.
- Muujinta elektarooniga ah ee LED 1/4 qaabka iskaanka mabda'a shaqada:
Waxay ka dhigan tahay in sahayda korantada V1-V4 ee xariiq kasta la shidyo 1/4 wakhtiga midkiiba iyadoo loo eegayo shuruudaha xakamaynta gudaha 1 qaab muuqaal ah. Faa'iidada tani waa in sifooyinka soo bandhigida LED-yada si wax ku ool ah looga faa'iidaysan karo kharashaadka qalabkana waa la dhimi karaa. Khasaaraha ayaa ah in khad kasta oo LED-yadu ay ku soo bandhigi karaan kaliya 1/4 wakhtiga 1 jir.
- Marka loo eego qaabka soocidda habka sawir-qaadista nooca bandhiga elektiroonigga ah ee LED:
1. Indoor-ka buuxa ee midabka LED-ka qaabka sawirka elektiroonigga ah: P4, P5 ee joogtada ah ee 1/16, P6, P7.62 ee joogtada ah ee 1/8.
2. Midabka bannaanka buuxa ee qaabka sawirka shaashadda elektaroonigga ah ee LED: P10, P12 ee joogtada ah ee 1/2, 1/4, P16, P20, P25 ee taagan.
3. Midab kaliya iyo labajibbaaran LED qaabka iskaanka muraayadda shaashadda inta badan waa 1/4 joogto ah, 1/8 joogto ahiskaan, joogto joogto ah 1/16iskaan.
