Muujinta LED-ku waa sidaha ugu weyn ee xayeysiiska iyo dib-u-ciyaarista macluumaadka waayahan, iyo muuqaal qeexid sare wuxuu dadka u keeni karaa waayo-aragnimo muuqaal ah oo naxdin leh, waxyaabaha la soo bandhigayna waxay noqon doonaan kuwo macquul ah. Si loo gaaro bandhig heer sare ah, waa in ay jiraan laba arrimood, mid waa in isha filimku u baahan yahay HD buuxa, iyo tan kale waa in bandhiga LED uu u baahan yahay inuu taageero buuxda HD. Bandhiga LED-ka midabka buuxa ayaa dhab ahaantii u dhaqaaqaya soo bandhigid qeexitaan sare ah, markaa sidee baan u samayn karnaa midab buuxa oo LED ah oo cad?
1, Hagaajinta miisaanka cawl ee muraayadda midabka buuxa ee LED
Heerka cawl waxa loola jeedaa heerka dhalaalka oo laga sooci karo kan ugu madow ilaa kan ugu ifaya ee midabka keliya ee dhalaalka ah ee muraayadda midabka buuxa ee LED. Markasta oo uu sareeyo heerka cawl ee bandhiga LED, ayaa midabka hodanka ah iyo midabka dhalaalaya, midabka bandhigu waa hal, isbeddelkuna waa sahlan yahay. Horumarinta heerka cawl wuxuu si weyn u wanaajin karaa qoto dheeraanta midabka, si heerka bandhigga midabka sawirka uu u kordhiyo joomatari. Heerka xakamaynta grayscale LED waa 14bit ~ 20bit, taas oo ka dhigaysa heerka sawirka faahfaahinta xallinta iyo saamaynta bandhigga ee dhamaadka-dhamaadka sare alaabta soo bandhigay heerka sare ee dunida. Horumarinta tignoolajiyada qalabka, miisaanka cawl ee LED wuxuu sii wadi doonaa inuu horumariyo si sax ah kantaroolka sare.
2, Hagaajinta isbarbardhigga bandhigga LED
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 oo dhalaalaya. Kala duwanaanshiyaha sare wuxuu aad u caawinayaa hufnaanta sawirka, waxqabadka tafatirka, iyo waxqabadka cabbirka cawl. Qaar ka mid ah bandhigyada fiidiyooga ah ee leh kala duwanaansho madow iyo caddaan ah, farqiga sare ee RGB LED wuxuu leeyahay faa'iidooyin kala duwanaansho madow iyo caddaan ah, caddayn, daacadnimo, iwm. Isbarbardhigga ayaa saameyn weyn ku leh saameynta bandhigga ee muuqaalka 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 ee noocan oo kale ah. Dhab ahaantii, hagaajinta saamiga isbarbardhigga bandhigga midabka buuxa ee LED-ka ayaa inta badan ah in la wanaajiyo dhalaalka midabka buuxa ee LED-ka iyo in la yareeyo muraayadda dusha sare ee shaashadda. Si kastaba ha ahaatee, dhalaalku maaha mid sarreeya sida suurtogalka ah, aad u sarreeya, waxay noqon doontaa mid aan waxtar lahayn, iyo wasakhowga iftiinka ayaa hadda noqday meel kulul. Mawduuca dooda, dhalaalka aadka u sarreeya ayaa saameyn ku yeelan doona deegaanka iyo dadka. Midabka buuxa ee LED-ka ee tuubada iftiiminta iftiinka waxay maraysaa habayn gaar ah, taas oo yareyn karta milicsiga guddiga LED-ka iyo hagaajinta isbarbardhigga muuqaalka midabka buuxa ee LED.
3, Yaree heerka pixel ee soo bandhigida LED
Yaraynta booska pixel ee bandhigga midabka buuxa ee LED wuxuu si weyn u wanaajin karaa caddayntiisa. Markasta oo ay yaraato booska pixel-ka ee bandhiga LED, ayaa soo bandhigida shaashadda LED-ka ee jilicsan. Si kastaba ha ahaatee, qiimaha soo gelistiisu waa mid aad u weyn, qiimaha midabka buuxa ee LED-ka ee la soo saaray ayaa sidoo kale sarreeya. Hadda suuqa ayaa sidoo kale u koraya dhanka bandhigyada LED-yada yar yar.
