Cutubka Labaad: Darawalka LED-ka, qaybta labaad ee ugu muhiimsan ee muujinta hogaanka.

Haddii nalalka LED-ka loo tixgeliyo inay yihiin jidhka bini'aadamka, markaa bandhigga LED IC waa qayb muhiim ah sida habka dhexe ee neerfayaasha maskaxda bini'aadamka, waxayna mas'uul ka tahay ficillada jirka ee jirka iyo fikirka maskaxda ee maskaxda.

Waxqabadka darawalka IC wuxuu go'aamiyaa saameynta shaashadda muraayadda, gaar ahaan isticmaalka waxqabadyada ballaaran ee casriga ah iyo goobaha sare, taas oo dadka ka dhigaysa shuruudo adag oo loogu talagalay darawalka bandhiga LED IC.

WadidKobcinta IC:
In 90s ee qarnigii la soo dhaafay, codsiyada bandhigay LED waxaa u badan midabo hal iyo double, isticmaalaya darawal koronto joogto ah IC. Sannadkii 1997-kii, Shiinaha ee ugu horreeyay ee LED-ga ayaa soo bandhigay chip kontoroolka darawalnimada 9701. Waxay ku fidday 16 hadhka cawl ilaa 8192 hadhka cawl si loo gaadho WYSIWYG.

Ka dib, sifooyinka iftiiminta LED-ka, wadista joogtada ah ee hadda jirta si ay u noqoto doorashada la doorbido darawalka bandhiga LED-ka oo buuxa, halka 16-kanaal ee isku dhafan ee isku dhafan uu beddelayo wadista 8-kanaalka. Dabayaaqadii 1990-meeyadii, Toshiba ee Japan, Allegro, iyo Ti ee Maraykanka ayaa si isdaba joog ah u soo bandhigay 16-kanaal oo joogto ah chips darawalka LED.

 Bilowgii qarnigii 21-aad, chips-yada darawallada ee shirkadaha Shiinaha ee Taiwanese ayaa sidoo kale la soo saaray oo la isticmaalay. Maanta, si loo xalliyo dhibaatada qaabeynta PCB ee muraayadaha muraayadaha yar yar ee LED-yada, qaar ka mid ah soosaarayaasha IC-ga ayaa sidoo kale soo bandhigay 48-channel LED chips darawal joogto ah oo joogto ah.

Tilmaamayaasha waxqabadka darawalka IC:
Waxaa ka mid ah tilmaamayaasha waxqabadka ee shaashadaha bandhiga LED, heerka cusboonaysiinta iyo heerka cawl iyo muujinta sawirka ayaa ah mid ka mid ah tilmaamayaasha ugu muhiimsan.

Tani waxay u baahan tahay joogteynta sare ee hadda u dhexeeya darawalka bandhiga LED IC channels, heerka isgaadhsiinta xawaaraha sare leh, iyo xawaaraha jawaabta joogtada ah ee hadda jira.

Waagii hore, saddexda dhinac ee heerka cusboonaysiinta, cabbirka cawliga, iyo heerka ka faa'iidaysigu waxay ahaayeen nooc xidhiidh beddela.

Si loo hubiyo in mid ama labadaba tilmaamayaashu ay noqon karaan kuwo aad u wanaagsan, waa inaan si habboon u hurnaa labada tilmaame ee soo hadhay.

Sababtan awgeed, bandhigyo badan oo LED ah ayaa ku adag in la gaaro sida ugu wanaagsan ee labada adduun ee codsiyada la taaban karo, ama si ku filan loo cusbooneysiiyey.

Qalabka kamaradaha xawaaraha sare leh waxay u nugul yihiin khadadka madow marka la sawiro, ama miisaanka cawlku kuma filna, iftiinka midabkuna waa mid aan iswaafajin.

Horumarka tignoolajiyada soosaarayaasha darawalka IC, waxaa jiray horumarro laga gaaray seddexda arrimood ee ugu sarreeya dhibaatooyinkaasna waa la xalliyay.
Codsiga bandhigga LED-ka-yar-yar, si loo hubiyo in isticmaalaha indhihiisa raaxada leh muddo dheer, iftiin yar iyo cawl-sare ayaa noqda halbeeg gaar ah oo muhiim ah oo lagu tijaabinayo waxqabadka darawalka IC.

Darawalka IC waa in lagu dhex daro wareegga weyn ee chip yar si uu u shaqeeyo, si awoodda wareegga ee muuqaalka muuqaalka LED-ka si fiican loo hagaajiyay, IC wanaagsan ilaa HD LED tayada muuqaalka, Midabku waxay leeyihiin saameyn muuqaal ah oo weyn. Si loo xaqiijiyo soo noqnoqoshada sare ee soo noqnoqda, taxanaha caanka ah ee IC hadda la isticmaalo waa: MBI5153, ICN2163, SUM6086, iwm.

 Ilaa hadda ICN2153 si dhakhso leh ugu koraan suuqa, sidoo kale aad bay u xasilloon tahay laakiin qiimo jaban marka la barbar dhigo MBI5153.

MBI5153 waxay ka timid Macroblock, waa chip-ka darawalka ee muujinta midabka buuxa ee LED. S-PWM waxa loo istcimaalay in lagu dhimo bilicda sawirka

Xogta sawirka galitaanka waxaa loo isticmaalaa in lagu hagaajiyo dhalaalka shaashadda fiidyaha LED. Heerkulka shaqadu waa -40 ilaa +85 darajo Celsius.

ICN2153 waxay ka timid Chip One. Waxay codsatay muuqaal-yar oo muuqaal ah oo LED ah oo leh faragelin heer sare ah.

Saamaynta labbiska hoose ee cawlan ma saamayso PCB-ga.

Waxay hagaajin kartaa wax soo saarka hadda waxayna si sax ah u xakameyn kartaa dhalaalka HD-ga LED-ga.

Bandhigga si wax ku ool ah ayaa loo xalliyaa. Baloogyada cawlan-hooseeya, iyo sidoo kale kabka midabka, jeexjeexyada, iwm. ayaa loo isticmaali karaa xariiq kasta si loo baabi'iyo rooxaanta qoraalka.

 YONWAYTECHMuujinta hogaaminta sida soo saaraha xirfadlaha ah, waxaan had iyo jeer qadarineynaa amar kasta oo lagu kalsoonaan karo oo ka yimaada macmiilkayaga, 1920hz-3840hz heerka cusbooneysiinta iyo 14bit-16bit screen LED ee isticmaalka gudaha ama dibadda waxay noqon kartaa ikhtiyaar.
