Qaybaha LED-yada-yar-yar ayaa kordhay, waxayna bilaabeen inay la tartamaan DLP iyo LCD suuqa bandhiga gudaha. Marka loo eego xogta ku saabsan miisaanka suuqa soo bandhigida LED-ga caalamiga ah, laga bilaabo 2018 ilaa 2022, faa'iidooyinka waxqabadka ee alaabada soo bandhigida LED-ga yar ayaa noqon doona mid cad, samaynta isbeddel lagu beddelayo teknoolojiyadda LCD iyo DLP ee dhaqameed.
Qaybinta warshadaha ee macaamiisha LED-pitch-yar
Sanadihii la soo dhaafay, LED-yada yaryar waxay ku guuleysteen horumar degdeg ah, laakiin sababtoo ah kharashka iyo arrimaha farsamada, hadda waxaa inta badan loo isticmaalaa goobaha bandhigga xirfadeed. Warshadahani maaha kuwo xasaasi u ah qiimaha badeecadaha, laakiin waxay u baahan yihiin tayada bandhiga oo aad u sarreeya, markaa waxay si dhakhso ah u qabsadaan suuqa xagga bandhigyada gaarka ah.
Horumarinta LED-yada-yar-yar oo ka yimid suuqa bandhiga ee u heellan suuqyada ganacsiga iyo rayidka. Wixii ka dambeeya 2018, sida tignoolajiyada bislaado kharashkuna hoos u dhaco, LED-yada yaryar ayaa ku qarxay suuqyada bandhigyada ganacsiga sida qolalka shirarka, waxbarashada, suuqyada wax iibsiga, iyo tiyaatarada filimada. Baahida loo qabo LED-yada yar-yar ee dhamaadka-sare ee suuqyada dibedda ayaa sii kordhaya. Todobo ka mid ah siddeedda shirkadood ee ugu sarreeya adduunka ayaa ka yimid Shiinaha, siddeedda shirkadood ee ugu sarreeya waxay xisaabiyaan 50.2% saamiga suuqa adduunka. Waxaan aaminsanahay in marka cudurka faafa ee taajka cusub uu xasilo, suuqyada dibadda ay dhowaan soo kici doonaan.
Isbarbardhigga LED-ga yar-yar, LED-yar, iyo Micro LED
Saddexda tignoolajiyada soo bandhigida ee kor ku xusan waxay dhamaantood ku saleysan yihiin qaybo yar yar oo kiristaalo LED ah sida dhibcood pixel luminous, farqigu wuxuu u dhexeeyaa fogaanta udhaxeysa laambada ku dhow iyo cabbirka jajabka. Mini LED iyo Micro LED waxay sii yareynayaan kala dheereynta kuulka laambada iyo cabbirka jajabka iyadoo lagu saleynayo LED-yada yaryar, kuwaas oo ah isbeddelka guud iyo jihada horumarinta tignoolajiyada soo bandhigida mustaqbalka.
Farqiga u dhexeeya cabbirka chip-ka awgeed, qaybaha kala duwan ee tignoolajiyada soo bandhigidda way kala duwanaan doonaan, iyo booska pixel-ka yar macnaheedu waa fogaan daawasho dhow.
Falanqaynta Tignoolajiyada Baakadaha LED Pitch Yar
SMDwaa soo gaabinta aaladda korka sare. Chip-ka qaawan waxa uu ku xidhan yahay gunta, iyo xidhiidhka korantada waxa la sameeyaa inta u dhaxaysa electrodes togan iyo taban iyada oo loo marayo silig birta ah. Xabagta epoxy-ga waxaa loo isticmaalaa in lagu ilaaliyo kuulka nalalka LED-ka ee SMD. Laydhka LED waxa lagu sameeyaa alxanka dib u qulqulaya. Kadib tusbaxyada lagu alxanayo PCB-ga si ay u sameeyaan cutubka bandhiga, moduleka waxaa lagu rakibay sanduuqa go'an, waxaana lagu daraa korontada, kaarka xakamaynta iyo siliga si ay u sameeyaan shaashadda LED-ga ee dhammaatay.
Marka la barbardhigo xaaladaha kale ee baakadaha, faa'iidooyinka alaabooyinka baakadaysan ee SMD ayaa ka miisaan culus khasaarooyinka, waxayna la socdaan sifooyinka baahida suuqa gudaha (go'aaminta, soo iibsiga, iyo isticmaalka). Waxay sidoo kale yihiin alaabooyinka caadiga ah ee warshadaha waxayna si dhakhso ah u heli karaan jawaabaha adeegga.
COBNidaamku waa in si toos ah loogu dhejiyo chip LED-ka PCB-ga oo leh koollo wax-qabad ama aan fiicneyn, oo la sameeyo isku-xidhka siliga si loo gaaro xiriirinta korantada (habka kor u qaadida togan) ama isticmaalka tignoolajiyada chip flip-chip (iyada oo aan lahayn fiilooyinka birta) si loo sameeyo mid togan iyo taban. electrodes ee kuul laambad si toos ah ugu xiran xiriirka PCB (teknoolajiyada flip-chip), iyo ugu dambeyntii module unit bandhigay la sameeyay, ka dibna module ah waxaa lagu rakibay on sanduuqa go'an, oo leh koronto, kaarka xakamaynta iyo silig, iwm samee shaashada soo bandhigta LED ee dhammaatay. Faa'iidada tignoolajiyada COB waa in ay fududeyso habka wax soo saarka, hoos u dhigto qiimaha alaabta, hoos u dhigto isticmaalka tamarta, sidaas darteed heerkulka dusha sare ee bandhiggu waa la dhimay, isbarbardhigga ayaa si weyn loo hagaajiyay. Khasaaraha ayaa ah in isku halaynta ay la kulmaan caqabado waaweyn, way adagtahay in la dayactiro laambada, dhalaalka, midabka, iyo midabka khadku wali way adagtahay in la sameeyo Si joogto ah.
IMDwuxuu isku daraa kooxaha N ee kuulka laambada ee RGB unug yar si ay u sameeyaan laambad. Jidka farsamada ee ugu muhiimsan: Common Yang 4 in 1, Common Yin 2 in 1, Common Yin 4 in 1, Common Yin 6 in 1, etc. Faa'iidada ay leedahay waxay ku jirtaa faa'iidooyinka baakadaha isku dhafan. Xajmiga kuulku wuu ka weyn yahay, korka dusha sare waa sahlan yahay, waxaana la gaari karaa dhibicda yar ee dhibicda, taas oo yaraynaysa dhibka dayactirka. Faa'iido darrooyinkeedu waa in silsiladda warshadaha ee hadda jirta aysan ahayn mid qumman, qiimuhu waa sarreeyaa, kalsoonidana waxay wajahaysaa caqabado waaweyn. Dayactirka waa mid aan habboonayn, oo joogtaynta dhalaalka, midabka, iyo midabka qalinka lama xallin oo waxay u baahan tahay in la sii wanaajiyo.
Micro LEDwaa in lagu wareejiyo qadar aad u badan oo wax-ka-qabashada ah oo laga soo qaado qalabyada LED-ka ee dhaqameed iyo yaraynta substrate-ka wareegga si loo sameeyo LED-yada ultra-fine-pitch. Dhererka LED-ka-milimitirka ayaa sidoo kale hoos loogu dhigayaa heerka micron si loo gaaro pixels ultra-sare iyo xallin ultra-sare ah. Aragti ahaan, waxaa lagu waafajin karaa cabbirrada shaashadaha kala duwan. Waqtigan xaadirka ah, tignoolajiyada muhiimka ah ee ciribtirka Micro LED waa in la jebiyo tikniyoolajiyadda habka miniaturization iyo tignoolajiyada wareejinta tirada badan. Marka labaad, tignoolajiyada wareejinta filimka khafiifka ah waxay jebin kartaa xadka cabbirka waxayna dhamaystiraysaa wareejinta dufcada, taas oo la filayo inay hoos u dhigto kharashka.
GOBwaa tignoolajiyada lagu daboolayo dhammaan dusha sare ee modules-yada dusha sare. Waxay ku dhejisaa lakabka kolloid hufan oo ku yaal dusha sare ee qaybaha yaryar ee SMD ee dhaqanka si loo xalliyo dhibaatada qaabka xooggan iyo ilaalinta. Nuxur ahaan, wali waa badeecad yar oo SMD ah. Faa'iidada ay leedahay waa in la yareeyo nalalka dhintay. Waxay kordhisaa xoogga ka-hortagga-shoogga iyo ilaalinta dusha sare ee kuulka laambada. Khasaarooyinkeeda ayaa ah in ay adagtahay in la dayactiro laambadda, qallafsanaanta moduleka oo ay keento diiqada colloidal, milicsiga, degummingka deegaanka, midabka kolloidal, iyo hagaajinta adag ee alxanka farsamada.
