Kodi COB LED Display ndi chiyani kwenikweni?
Chifukwa cha kufunafuna kwaumunthu chiwonetsero cha LED chowongolera kwambiri, mawonekedwe a pixel a zowonetsera za LED akucheperachepera.
Monga m'badwo woyamba waukadaulo wowonetsera, chiwonetsero chachikhalidwe cha SMD chakhala chokhwima kwambiripatatha zaka zoposa khumichitukuko.
Ndiye, ndi njira iti yaukadaulo yomwe pamapeto pake idzafune mu nthawi ya mawonedwe ang'onoang'ono a LED?
Ndi chitukuko chaukadaulo wowonetsera ma LED, njira zamaukadaulo monga COB (Zofupikitsa za Chip On Board) zimatuluka.
Komanso, njira zonyamula katundu zimatha kufananizidwa ndi mitundu yosiyanasiyana ya chip.
SMD, yomwe imadziwika kuti zida zokwera pamwamba, imatanthawuza kugwiritsa ntchito ukadaulo wa pamwamba pakupanga zida za LED.
Itha kuyika chikho cha nyali, bulaketi, chinthu cha kristalo, ndi zinthu zina m'mitundu yosiyanasiyana ya mikanda ya nyali.
Popanga chowonetsera chokhala ndi masitayilo osiyanasiyana a zowonetsera zazing'ono za LED, mkanda wa nyali umawotchedwa ku bolodi la dera ndi makina othamanga kwambiri a SMT okhala ndi kuwotcherera kwapamwamba kwambiri.
Poganizira zovuta zaukadaulo panthawi ya encapsulation, opanga amakonda SMD kuti ipange chowonera chaching'ono cha digito cha LED.
SMD ndiye ukadaulo woyamba wa zowonetsera zazing'ono za LED zokhala ndi ma pixel ochepera 10mm pamsika.
Kumbali ina, COB, yachidule cha Chip On Board, ndi ukadaulo watsopano woyika zinthu womwe umatsekereza tchipisi ta LED, osati magetsi a LED, molunjika pa PCB.
Chifukwa chake, COB-LED idzamasulidwa ku kukula kwakuthupi kwa SMD kuti ikhale yopambana kwambiri ngati P0.9375.
Za digitozowonetsera zazing'ono zowongolera mu P0.9375mm, P1.25mm, P1.5625 mm ndi P1.875 zilipo ndi COB.
Kuphatikiza apo, ndizosatsutsika kuti COB ili ndi mawonekedwe abwinoko.
Ma module omwe ali ndi COB sakhala opepuka kuposa omwe ali ndi SMD komanso amakhala ndi mawonekedwe okulirapo.
Poyerekeza ndi SMD, zomwe COB zotsogola zowonetsera zingabweretse phindu kwa inu monga pansipa:
1; Kutentha kwabwino kwambiri
Chimodzi mwa zolinga za teknolojiyi ndi kuthana ndi vuto la kutentha kwa SMD ndi DIP.
Mapangidwe osavuta amapereka ubwino pa mitundu iwiri ya kutentha kwa kutentha.
2; Oyenera yopapatiza phula phula LED Display
Pamene tchipisi zimalumikizidwa mwachindunji ndi bolodi la PCB, mtunda pakati pa gawo lililonse ndi wopapatiza kuti muchepetse kuchuluka kwa pixel kuti apatse makasitomala zithunzi zomveka bwino.
3; Sang'anirani zoyikamo
Monga tafotokozera pamwambapa, mawonekedwe a COB LED ndi osavuta kuposa SMD ndi GOB, kotero kuyika kwake ndikosavuta, nakonso.
4; Mulingo wapamwamba wosalowa madzi
Ndi chipangizo chatsopano pa bolodi la module yomatira, imatha kuteteza LED pa module ya LED kumadzi kapena chinyezi.
5; Bwino Anti-kugundana
Kupanga kwapadera kokhala ndi anti-collision gluing kumatha kukhala ndi umboni wodabwitsa, kumapereka chitetezo chapamwamba kwambiri cha ma LED pazotsatira zosiyanasiyana.
6; Kupitilira fumbi.
Ndi kusindikiza kwakukulu kwa zinthu zatsopano, mawonekedwe a COB LED screen kuchokera ku YONWAYTECH LED ndi opanda fumbi momveka bwino ndipo amapereka mawonekedwe abwino kwambiri otsitsimula kwambiri komanso mtundu wofanana.
Chifukwa chodalirika kwambiri ndikuti ukadaulo wa COB ukhoza kuthetsa ulalo wowongolera munjira imodzi yopanga nyali.
Kuphatikiza apo, imachotsanso mkanda wa nyali panjira yowotcherera, kotero kuti kutentha kwakukulu munjira yachikhalidwe sikungakhudze chingwe cha LED ndi kuwotcherera.
Kutentha kwabwino kwambiri komanso kukana kwa okosijeni kumathandizanso kudalirika kwambiri.
Kuphatikiza apo, COB imatengera ukadaulo wapamwamba kwambiri wokutira kuti muteteze kulephera kwa mawonekedwe a LED chifukwa cha madzi, chinyezi, UV, ndi zowonongeka zina.
Imathandizira magwiridwe antchito a nyengo yonse ndipo imatha kugwirabe ntchito potentha kwambiri -30 mpaka +80 madigiri.
Chitetezo chokwanira chimalepheretsa kugunda kapena kukwapula.
Zowonetsera zazing'ono za LED zimatha kutsukidwa ndi nsalu yonyowa ngati zadetsedwa.
Ndizidziwitso pamwambapa, mutha kuzindikira kuti ukadaulo wa COB ndi wapamwamba kuposa ukadaulo wa SMD pazithunzi zowonetsera za LED.
Ndipo ngati mukufunaMawonekedwe a Micro LED, mutha kulozera kuzinthu zina za YONWAYTECH LED DISPLAY.
Lumikizanani ndi gulu la YONWAYTECH LED DISPLAY kuti mumve zambiri chonde.
