Xilligii bandhigga-yar-yar, waxaa weli jira caqabado badan oo farsamo si loo hagaajiyo tayada sawirka
As Micro-LEDwaxa uu galaa waa cusub, macaamiishu waxa ay sidoo kale soo bandhigeen shuruudo sare oo muujinaya tayada sawirka.Sida loo hagaajiyo tayada muuqaalka muuqaalka ayaa noqotay cilmi-baaris muhiim ah iyo jihada horumarinta ee shirkadaha shaashadda.Tan iyo qarnigii 21aad, horumarinta tignoolajiyada warshadaha bandhiga 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 codsiga cusub, gaar ahaan dhinaca ganacsiga iyo suuqa bandhiga dhinaca dawladda waa meel walba.soo saaraha bandhiga LED, Si aad u barato tignoolajiyada udub-dhexaadka u ah bandhigga cabbirka weyn ee Mini/Micro-LED, waxaa jira saddex arrimood: mid waa in uu shaqo fiican ka qabto alaabtiisa hardware-ka ah, tan labaadna waa in la yeesho nidaam kontorool, tan saddexaadna waa in ay noqotaa yaqaan macaamiisha 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-LEDiyo teknoolajiyada Micro-LED waxay sameeyeen isbeddello qoto dheer.Midda koowaad waa saxsanaan sare, wareejinta saxda ah ee saxda ah iyo tignoolajiyada isku xidhka ee jajabyada yar yar, ogaanshaha saxda ah ee saxda ah iyo tignoolajiyada dayactirka yar-
chips size, iyo wadida ganaaxa iyo farsamada sixitaanka ku salaysan hadda 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 waxay ka kooban tahay LEDs badan oo kala duwan, sababtoo ah kala firdhisanaanta 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.
