Maaddaama Micro-LED uu galo xilli cusub, macaamiishu waxay sidoo kale soo bandhigeen shuruudo sare oo loogu talagalay tayada muuqaalka.Sida loo hagaajiyo tayada sawirka waxay noqotay cilmi-baaris muhiim ah iyo jihada horumarinta ee shirkadaha shaashadda.Laga soo bilaabo qarnigii 21aad, horumarka tignoolajiyada soo bandhigista LED si buuxda uma horumarin si waafaqsan sharciga Heitz.
Isbeddelka horumarinta tignoolajiyada warshadaha ee LED-ka ayaa inta badan ah in chip-ku uu sii wado inuu hoos u dhaco oo garoonku pixel uu sii wado inuu hoos u dhaco;Qiimaha hal chip LED ayaa hoos u sii socda, dhalaalkuna wuu sii kordhayaa; Si joogto ah u baadh qaybaha codsiyada cusub, gaar ahaan dhinaca ganacsiga iyo suuqa bandhiga dhinaca dawladda waa meel walba.Sida soo saaraha soo-saarka LED-ka, si loo aqoonsado tignoolajiyada asaasiga ah eeMuqaal yar yar/Mikro-LED oo cabbir weyn, waxaa jira saddex arrimood: mid waa in ay shaqo fiican ka qabtaan alaabta hardware u gaar ah, ka labaad waa in ay leeyihiin nidaamka xakamaynta, iyo saddexaad waa in la yaqaan macaamiisha ee qaybta suuqa codsiga.Logic si loo keeno isdhexgalka LED suuqa.
Chip si loo xakameeyo nidaamka, ka sii muhiimsan, hagaajinta indhaha iyo nidaamka xakamaynta.Micro-LED waa dariiqa ugu fiican, laakiin sidoo kale waxay la kulmeysaa caqabado badan oo farsamo: tusaale ahaan, 1. Chip miniaturization wuxuu yareeyaa waxtarka iftiinka ee hal jajab wuxuuna kordhiyaa kulaylka;2. Chip miniaturization waxay keentaa isbeddel ku yimaada joogteynta shucaaca iftiinka ee hoos yimaada hawlgalka hadda socda.Miskiin;3. Wada hadalka indhaha ee u dhexeeya pixels ku xiga waa halis;4. Kharashka tijaabinta chip-ka ayaa si aad ah kor ugu kacay, iyo chips-yada Micro-LED xitaa ma gaari karaan tijaabada EL;Boodhka iyo qaybo ka mid ah waxay saameyn weyn ku leeyihiin xagasha iftiinka soo saarta, waxayna xitaa xannibaan iftiinka-firfircoon ee chip si ay u noqdaan "pixel dhintay iftiin iftiin leh";6. Yaraynta chip-ku waxay keentaa koror weyn oo ku saabsan hagaajinta pixel iyo kharashyada adeegga ka dib.Tusaale ahaan, macmiilka COB ayaa ah mid aan suurtagal ahayn in la dayactiro, kaliya ku soo celi soo saaraha soo bandhigay.
Min-LED iyo teknoolojiyadda Micro-LED waxay soo mareen isbeddello qoto dheer.Midka koowaad waa saxsanaanta sare, wareejinta saxda ah ee saxda ah iyo tignoolajiyada isku xidhka ee chips-yada yar yar, ogaanshaha saxda ah ee saxda ah iyo tignoolajiyada dayactirka jajabyada yar yar, iyo wadida wadida iyo tignoolajiyada hagaajinta ee ku salaysan yar yar;Tignoolajiyada baakadaha iyo agabka, tignoolajiyada xakamaynta bandhigga oo aad isugu dhafan;ugu dambeyntii, tiknoolijiyada saxda ah ee taranka midabka (midabka) ee heerarka gamut midab kala duwan, tiknoolijiyada farsamaynta ganaaxa sare ee grayscale (processing grayscale) oo ku salaysan PQ ama HLG curves ee heerarka HDR kala duwan, Dhaqdhaqaaqa qumman ee tayada sawir-qaadista farsamada (algorithm).
Xilligii bandhigga-yar-yar, sida dib loo fahmo loona qeexo tayada sawirka?Shi Changjin waxa uu rumaysan yahay in ay tahay in waxoogaa horumar ah lagu sameeyo miisaanka cawl sare, midabka midabka balaadhan, dib u cusboonaysiinta sare, iyo joogteynta cad sare.Tusaale ahaan, midab-cawlan sare + dhalaalka sare ee sare wuxuu gaari karaa kala duwanaansho firfircoon;labaad, gamut midabka ballaaran + xagal daawashada ultra-ballaaran, hagaajinta joogtaynta xaglaha daawashada waaweyn;saddexaad, cusbooneysiin sare + heerka jir sare, gaaritaanka saamaynta sawir garaafyada dhaqdhaqaaqa wanaagsan, joogteynta cad sare + joogteynta madow, hubinta wanaagsan Saamaynta isha iftiinka dusha.
Xilliga baakadaha isku-dhafka ah, muhiimada madow ayaa aad uga sarreeya tan xilliga caadiga ah ee SMD.Tusaale ahaan, haddii madowga dusha sare aan si fiican loo maamulin, dhacdada mosaic-ka madow waxay noqon doontaa mid muuqata.SMD wuxuu ka kooban yahay waxyaabo badan oo kala duwanLEDs, sababtoo ah kala firdhinta iftiinka waxay daciifisaa saamaynta muraayadda madow ee shaashadda.Intaa waxaa dheer, waxaa jira iftiin muuqda oo u rogi doona muraayadda muraayadda.Milicsiga muuqaalku wuxuu si dhab ah u hoos u dhigi karaa tayada sawirka marka iftiinka hareeruhu uu xooggan yahay.
