Isahluko sesibini: Umqhubi we-LED, inxalenye yesibini ebaluleke kakhulu kumboniso okhokelwayo.

Ukuba izibane ze-LED zithathwa njengomzimba womntu, ngoko ke umqhubi we-LED obonisa i-IC licandelo eliphambili njengenkqubo ye-nervous yengqondo yomntu, kwaye ilawula izenzo zomzimba kunye nokucinga kwengqondo yengqondo.

Ukusebenza komqhubi we-IC umisela umphumo weskrini esikhokeleyo somboniso, ngokukodwa ukusetyenziswa kwemisebenzi yanamhlanje enkulu kunye neendawo eziphezulu, okwenza abantu bafune iimfuno ezingqongqo kwi-IC yomqhubi we-LED.

QhubaI-IC evolution:
Kwiminyaka engama-90 yenkulungwane yokugqibela, izicelo zokubonisa i-LED zazilawulwa ngumbala omnye kunye nembini, usebenzisa umqhubi we-voltage rhoqo IC. Ngo-1997, umboniso wokuqala we-LED waseTshayina ozinikeleyo wokulawula i-chip 9701 wavela. Ithathe i-16 shades yegrey ukuya kwi-8192 shades yegrey ukufezekisa i-WYSIWYG.

Emva koko, kwiimpawu ezikhupha ukukhanya kwe-LED, i-drive eqhubekayo-yangoku ibe yinto ekhethiweyo yomqhubi ogcweleyo we-LED, ngelixa i-16-channel drive edibeneyo ithatha indawo ye-8-channel drive. Ekupheleni kweminyaka yoo-1990, uToshiba waseJapan, uAllegro, kunye noTi waseUnited States baye bazisa iitshiphusi zomqhubi we-LED ngokulandelelanayo.

 Ekuqaleni kwenkulungwane yama-21, iitshiphu zokuqhuba zeenkampani zaseTshayina zaseTaiwan nazo zaveliswa ngobuninzi kwaye zasetyenziswa. Namhlanje, ukuze kusonjululwe ingxaki yoyilo lwe-PCB lwezikrini ezibonisa ukukhanya kwe-LED, abanye abavelisi be-IC baye bazisa iitshiphusi zomqhubi zangoku ezihlanganisiweyo ezingama-48.

Iimpawu zokusebenza zomqhubi we-IC:
Phakathi kwezibonakaliso zokusebenza kwezikrini zokubonisa i-LED, izinga lokuhlaziya kunye nenqanaba legrey kunye nokubonakaliswa komfanekiso yenye yezona zibonakaliso ezibalulekileyo.

Oku kufuna ukuhambelana okuphezulu kwangoku phakathi kwe-LED ebonisa umqhubi we-IC amashaneli, izinga lonxibelelwano olukhawulezayo lonxibelelwano, kunye nesantya sokuphendula ngokuqhubekayo.

Kwixesha elidlulileyo, imiba emithathu yezinga lokuhlaziya, i-grayscale, kunye nesantya sokusetyenziswa yayiluhlobo lobudlelwane obuguqukayo.

Ukuqinisekisa ukuba enye okanye zombini zesalathisi zinokugqwesa ngakumbi, kufuneka ngokufanelekileyo sincame izalathisi ezibini eziseleyo.

Ngenxa yesi sizathu, ezininzi iziboniso ze-LED kunzima ukufikelela kuzo zombini ihlabathi kwizicelo eziphathekayo, okanye zihlaziywa ngokwaneleyo.

Izixhobo zekhamera ezikhawulezayo ziqhelekile kwimigca emnyama xa zifotwa, okanye isikali esingwevu asanelanga, kwaye ukuqaqamba kombala akuhambelani.

Ngokuqhubela phambili kwetekhnoloji yabavelisi be-IC yabaqhubi, kuye kwakho impumelelo kwimiba emithathu ephezulu kwaye ezi ngxaki zisonjululwe.
Ekusetyenzisweni komboniso omncinci we-LED, ukuze kuqinisekiswe amehlo akhululekileyo omsebenzisi ixesha elide, ukukhanya okuphantsi kunye ne-high-gray kuba ngumgangatho obaluleke kakhulu wokuvavanya ukusebenza komqhubi we-IC.

Umqhubi we-IC ukudibanisa isiphaluka esikhulu kwi-chip encinci ukuze asebenze, ukwenzela ukuba amandla esekethe emboniso wevidiyo ye-LED aphuculwe ngcono, i-IC enhle ukuya kwi-HD i-HD yekhwalithi yevidiyo ebonisa i-LED, Imibala inempembelelo enkulu ebonakalayo. Ukufumana ukuhlaziya okuphezulu, uthotho lwangoku lwe-IC olusetyenziswayo zezi: MBI5153, ICN2163, SUM6086, njl.

 Ukuza kuthi ga ngoku, i-ICN2153 ikhula ngokukhawuleza kwimarike, izinze kakhulu kodwa ngexabiso eliphantsi xa ithelekiswa ne-MBI5153.

I-MBI5153 ivela kwiMacroblock, sisitshiphu somqhubi sokubonisa umbala ogcweleyo we-LED. I-S-PWM isetyenziselwa ukunciphisa ukuqhwanyaza komfanekiso.

Idatha yomfanekiso wegalelo isetyenziselwa ukulungelelanisa ukukhanya kwesikrini sevidiyo ye-LED. Ubushushu bokusebenza ngu-40 ukuya +85 degrees Celsius.

I-ICN2153 ivela kwiChip One. Isetyenziswe kumboniso omncinci wevidiyo ye-LED enokuphazamiseka okuhle kakhulu.

Isiphumo esisezantsi-grey iyunifomu ayichatshazelwa yi-PCB.

Iyakwazi ukulungelelanisa imveliso yangoku kwaye ilawule ngokuchanekileyo ukukhanya kwe-HD isiboniso se-LED.

Umboniso usonjululwe ngempumelelo. Iibhloko eziphantsi-grey, kunye nokuphoswa kombala, i-pitting, njl.inokusetyenziswa kunye naluphi na umgca ukuphelisa iziporho zombhalo.

 YONWAYTECHUmboniso okhokelwayo njengomvelisi oqeqeshiweyo, sihlala siyixabisa iodolo nganye ethembekileyo evela kumxhasi wethu, ireyithi yokuhlaziya i-1920hz-3840hz kunye ne-14bit-16bit yesikrini esikhokelela kusetyenziso lwangaphakathi okanye lwangaphandle lunokuzikhethela.
