Isahluko Sesibili: I-LED Driver, ingxenye yesibili ebaluleke kakhulu yesibonisi esiholayo.

Uma izibani ze-LED zibhekwa njengomzimba womuntu, khona-ke umshayeli wesibonisi we-LED u-IC uyingxenye ebalulekile njengesistimu yezinzwa emaphakathi yobuchopho bomuntu, futhi uphethe izenzo zomzimba zomzimba nokucabanga kwengqondo kobuchopho.

Ukusebenza komshayeli we-IC kunquma umphumela wesikrini esibonisiwe esiholayo, ikakhulukazi ukusetshenziswa kwemisebenzi yesimanje emikhulu nezindawo ezisezingeni eliphezulu, okwenza abantu babe nezimfuneko eziqinile zomshayeli obonisa i-LED IC.

ShayelaUkuvela kwe-IC:
Ngawo-90s wekhulu leminyaka elidlule, izinhlelo zokusebenza zokubonisa i-LED bezibuswa umbala owodwa nokabili, kusetshenziswa umshayeli we-voltage ongashintshi we-IC. Ngo-1997, kwavela i-chip 9701 yokuqala yaseChina ebonisa i-LED. Ihlanganisa amathunzi angu-16 okumpunga kuya ku-8192 shades of gray ukuze kuzuzwe i-WYSIWYG.

Ngokulandelayo, ezicini ezikhipha ukukhanya kwe-LED, idrayivu eqhubekayo izoba yinketho ekhethwayo yomshayeli obonisa umbala ogcwele we-LED, kuyilapho idrayivu ehlanganiswe kakhudlwana eneziteshi ezingu-16 ingena esikhundleni sedrayivu yeziteshi ezingu-8. Ngasekupheleni kwawo-1990, abakwa-Toshiba, u-Allegro, no-Ti base-United States base-United States bethula ngokulandelana ama-chips amanje okushayela e-LED angu-16.

 Ekuqaleni kwekhulu lama-21, ama-driver chips ezinkampani zaseShayina zaseTaiwan nawo akhiqizwa ngobuningi futhi asetshenziswa. Namuhla, ukuze kuxazululwe inkinga yokuhlelwa kwe-PCB yezikrini zokubonisa ze-LED ezine-pitch encane, abanye abakhiqizi be-IC bomshayeli nabo bethule ama-chips amanje amanje omshayeli ahlanganiswe kakhulu we-48-channel LED.

Izinkomba zokusebenza kwe-Driver IC:
Phakathi kwezinkomba zokusebenza kwezikrini zokubonisa ze-LED, izinga lokuvuselela kanye nezinga elimpunga nokubonakaliswa kwesithombe kungenye yezinkomba ezibaluleke kakhulu.

Lokhu kudinga ukungaguquguquki okuphezulu kwamanje phakathi kwamashaneli e-IC yesishayeli esibonisiwe se-LED, izinga lokuxhumana olunesivinini esikhulu, kanye nesivinini sokuphendula esiqhubekayo samanje.

Esikhathini esedlule, izici ezintathu zenani lokuvuselela, isikali esimpunga, kanye nezinga lokusebenzisa zaziwuhlobo lobudlelwano obushintshayo.

Ukuqinisekisa ukuthi inkomba eyodwa noma zombili zingaba zinhle kakhulu, kufanele sidele izinkomba ezimbili ezisele.

Ngenxa yalesi sizathu, izibonisi eziningi ze-LED zinzima ukuzuza okungcono kakhulu kwezindawo zombili ezinhlelweni zokusebenza ezingokoqobo, noma azivuselelwa ngokwanele.

Imishini yekhamera enesivinini esiphezulu ijwayele ukuba nemigqa emnyama uma ithwetshulwa, noma isikali esimpunga asanele, nokukhanya kombala akuhambisani.

Ngokuthuthuka kobuchwepheshe babakhiqizi be-IC yabashayeli, kube khona impumelelo ezindabeni ezintathu eziphezulu futhi lezi zinkinga sezixazululiwe.
Ekusetshenzisweni kwesibonisi se-LED esinephimbo elincane, ukuze kuqinisekiswe amehlo athokomele omsebenzisi isikhathi eside, ukukhanya okuphansi nokumpunga okuphezulu kuba izinga elibaluleke kakhulu lokuhlola ukusebenza komshayeli we-IC.

I-Driver IC iwukuhlanganisa umjikelezo omkhulu ku-chip encane ukuze isebenze, ukuze amandla wesifunda sesibonisi sevidiyo ye-LED athuthukiswe kangcono, i-IC enhle kuya ku-HD ikhwalithi yevidiyo yokubonisa i-LED, Imibala inomthelela omkhulu wokubuka. Ukuze uthole imvamisa ephezulu yokuvuselela, uchungechunge lwamanje oludumile lwe-IC olusetshenziswayo yilena: MBI5153, ICN2163, SUM6086, njll.

 Kuze kube manje i-ICN2153 ikhula ngokushesha emakethe, futhi izinze kakhulu kodwa ngezindleko eziphansi uma iqhathaniswa ne-MBI5153.

I-MBI5153 ivela ku-Macroblock, iyi-chip yomshayeli yesibonisi esinombala ogcwele we-LED. I-S-PWM isetshenziselwa ukunciphisa ukucwayiza kwesithombe.

Idatha yesithombe esifakiwe isetshenziselwa ukulungisa ukukhanya kwesikrini sevidiyo ye-LED. Izinga lokushisa lokusebenza -40 kuya +85 degrees Celsius.

I-ICN2153 ivela ku-Chip One. Isebenza ekubonisweni kwevidiyo ye-LED ene-pitch encane enokuphazamiseka okuhle kakhulu.

Umthelela ompunga ophansi awuthintwa yi-PCB.

Ingakwazi ukulungisa okukhiphayo kwamanje futhi ilawule ngokunembile ukukhanya kwesibonisi se-HD LED.

Isibonisi sixazululwa ngempumelelo. Amabhulokhi anombala ompunga okuphansi, kanye nokulingwa kombala, i-pitting, njll.kungasetshenziswa nanoma yimuphi umugqa ukuze kuqedwe izipoki zombhalo.

 YONWAYTECHisibonisi esiholayo njengomkhiqizi ochwepheshile, sihlala silazisa i-oda ngalinye elithembekile elivela kuklayenti lethu, isilinganiso sokuvuselela esingu-1920hz-3840hz kanye nesikrini esiholwa ngu-14bit-16bit esisetshenziswa ngaphakathi noma ngaphandle singazikhethela.
