Iyada oo horumarka joogtada ah ee sayniska iyo tignoolajiyada sannadihii la soo dhaafay, bandhigyada LED ayaa la aqoonsaday oo lagu dabaqay warshado kala duwan. Nuxurka la soo bandhigay ayaa noqonaya mid aad iyo aad u sarreeya. Sidee bay muujinta LED u gaari kartaabandhig heer sare ah ? Marka hore, sawirka iyo isha fiidiyowga waxay u baahan yihiin HD buuxa. Marka labaad, bandhiga LED wuxuu u baahan yahay inuu taageero buuxda HD. Saddexaad waa in la dhimo heerka pixel ee bandhigga LED. Midda afraad waa isku-darka bandhigga LED-ka iyo processor-ka fiidiyowga. Waqtigan xaadirka ah, bandhigyada midabka buuxa ee LED waxay sidoo kale u dhaqaaqayaan bandhigyo qeexid sare ah.
1, Hagaajinta saamiga isbarbardhigga ee muuqaalka midabka buuxa ee LED. Saamiga isbarbardhigga waa mid ka mid ah qodobbada muhiimka ah ee saameeya saamaynta aragga. Guud ahaan marka la eego, farqiga u sarreeya, ayaa sii caddaanaya sawirka iyo midabka dhalaalaya. Kala duwanaanshiyaha sare ayaa aad waxtar u leh hufnaanta sawirka iyo waxqabadka heerka cawl. Qaar ka mid ah bandhigyada qoraalka iyo fiidiyowga leh isbarbardhigga madow iyo caddaanka weyn, isbarbardhigga sare ee midabka buuxa ee LED wuxuu leeyahay faa'iidooyin kala duwanaansho madow iyo caddaan ah, fiiqan, iyo daacadnimo. Isbarbardhigga ayaa saameyn weyn ku leh saameynta bandhigga fiidyaha firfircoon. Sababtoo ah kala-guurka iftiinka iyo mugdiga ah ee sawirada firfircooni waa mid aad u dhakhso badan, farqiga u sarreeya, way u fududahay indhihii bini'aadamka si ay u kala saaraan habka kala-guurka. Dhab ahaantii, hagaajinta saamiga isbarbardhigga ee shaashadda midabka buuxa ee LED-ka ayaa inta badan ah in la wanaajiyo iftiinka muuqaalka midabka buuxa ee LED-ka iyo in la yareeyo muraayadda dusha sare ee shaashadda. Si kastaba ha ahaatee, dhalaalku maaha mid aad u sarreeya sida ugu macquulsan, aad u sarreeya, laakiin waxay noqon doontaa mid aan faa'iido lahayn, ma saameynayso oo kaliya bandhigga LED. nolosha, laakiin sidoo kale waxay keentaa wasakh khafiif ah. Qalabka LED-ka ee RGB LED-ka iyo tuubada iftiiminta iftiinka LED-ku waxay maraan farsamayn gaar ah, taas oo yareyn karta milicsiga guddiga LED-ka oo wanaajin kara isbarbardhigga bandhigga RGB LED.
2, Hagaajinta heerka cawl ee darbiga fiidiyoowga LED midabka buuxa. Heerka cawl waxa loola jeedaa heerka dhalaalka oo laga sooci karo kan ugu mugdiga badan ilaa kan ugu ifaya ee midabka keliya ee dhalaalka midabka buuxa ee LED-ka. Markasta oo uu sareeyo heerka cawl ee bandhiga midabka buuxa ee LED, ayaa midabka hodanka ah iyo midabka dhalaalaya. Hagaajinta heerka cawl wuxuu si weyn u wanaajin karaa qoto dheeraanta midabka, si heerka bandhigga midabka sawirka uu u kordhiyo joomatari. Heerka xakamaynta miisaanka cawl ee LED waa 14bit ~ 20bit, taas oo ka dhigaysa faahfaahinta heerka sawirka faahfaahinta xallinta iyo saamaynta bandhigga ee alaabada soo bandhigidda heerka sare ah inay gaaraan heerka sare ee adduunka. Horumarinta tignoolajiyada qalabka, miisaanka cawl ee LED wuxuu sii wadi doonaa inuu horumariyo saxnaanta xakamaynta sare.
3, Yaree garoonka pixel ee bandhiga LED midabka buuxa. Yaraynta booska pixel ee bandhigga midabka buuxa ee LED wuxuu si weyn u wanaajin karaa caddayntiisa. Markasta dhibicda dhibcaha ee muraayadda midabka buuxa ee LED, ayaa sii fiicnaan doonta. Si kastaba ha ahaatee, qiimahamuuqaal yar oo LED ah waa dhanka sare. Nasiib wanaag, suuqa ayaa hadda u koraya dhanka bandhigyada LED-yada yaryar.
4, Muujinta LED oo lagu daray processor-ka fiidiyowga. Fiidiyowga LED-ka wuxuu isticmaali karaa algorithms horumarsan si uu wax uga beddelo calaamadda tayada muuqaalka liidata, wuxuu sameeyaa taxane taxane ah sida is-dhexgalka, fiiqista cirifka, magdhowga dhaqdhaqaaqa, iwm, si kor loogu qaado faahfaahinta sawirka iyo hagaajinta tayada sawirka. Algorithm-ka farsamaynta sawirka sawirka processor-ka waxaa loo isticmaalaa si loo hubiyo in ka dib marka sawirka fiidyaha la miisaamo, caddaynta iyo heerka cawl ee sawirka la ilaaliyo ilaa xadka ugu badan. Intaa waxaa dheer, processor-ka fiidiyoogu wuxuu sidoo kale u baahan yahay inuu yeesho ikhtiyaaro hagaajinta sawirka iyo saamaynta hagaajinta, oo uu socodsiiyo iftiinka sawirka, isbarbardhigga, iyo cabbirka cawl si loo hubiyo in shaashadda ay soo saarto sawir jilicsan oo cad.
