Igice cya kabiri: LED Umushoferi, igice cya kabiri cyingenzi kubiyobora.

Niba amatara ya LED afatwa nkumubiri wumuntu, noneho LED yerekana umushoferi IC nikintu cyingenzi kimwe na sisitemu yo hagati yubwonko bwumuntu, kandi ishinzwe ibikorwa byumubiri hamwe nibitekerezo byubwonko.

Imikorere yumushoferi IC igena ingaruka zerekanwa ryerekanwe, cyane cyane ikoreshwa ryibikorwa binini bigezweho hamwe n’ibibuga byo mu rwego rwo hejuru, bigatuma abantu basabwa cyane cyane kuri LED yerekana umushoferi IC.

DriveUbwihindurize bwa IC:
Mu myaka ya za 90 yo mu kinyejana gishize, LED yerekana porogaramu yiganjemo amabara amwe kandi abiri, ukoresheje amashanyarazi ya voltage ihoraho. Mu 1997, Ubushinwa bwa mbere bwerekana LED bwagenewe kugenzura chip 9701. Yazengurutse igicucu cya 16 cyijimye kugeza 8192 igicucu cyumusatsi kugirango ugere kuri WYSIWYG.

Ibikurikiraho, kubiranga LED biranga urumuri, burigihe-burigihe kugirango uhindurwe guhitamo ibara ryuzuye rya LED yerekana umushoferi, mugihe imiyoboro myinshi ihuriweho na 16 isimbuza imiyoboro 8. Mu mpera z'imyaka ya za 90, Ubuyapani Toshiba, Allegro, na Ti yo muri Leta zunze ubumwe za Amerika bwagiye bukurikirana imiyoboro 16 ya buri gihe imashini itwara LED.

 Mu ntangiriro z'ikinyejana cya 21, imashini zitwara ibinyabiziga zo mu Bushinwa zo muri Tayiwani nazo zakozwe cyane kandi zirakoreshwa. Uyu munsi, kugirango dukemure ikibazo cyimiterere ya PCB yerekana ecran ntoya ya LED yerekana, bamwe mubakora ibinyabiziga IC bashizeho kandi imiyoboro ihuriweho na 48-imiyoboro ya LED ihoraho.

Ibipimo byerekana umushoferi IC:
Mubipimo byerekana imikorere ya LED yerekana ecran, kugarura igipimo nicyatsi cyurwego no kwerekana imvugo nimwe mubimenyetso byingenzi.

Ibi bisaba guhuzagurika cyane kurubu hagati ya LED yerekana umushoferi IC imiyoboro, umuvuduko wihuta woguhuza amakuru, hamwe nigisubizo gihoraho.

Mubihe byashize, ibintu bitatu byikigereranyo cyo kugarura ubuyanja, ibara ryinshi, nigipimo cyo gukoresha byari ubwoko bwimibanire.

Kugirango tumenye neza ko kimwe cyangwa byombi byerekana ibimenyetso bishobora kuba byiza cyane, tugomba kwigomwa bikwiye ibipimo bibiri bisigaye.

Kubwiyi mpamvu, ibyerekanwa byinshi LED biragoye kugera kubintu byiza byisi byombi mubikorwa bifatika, cyangwa ntibisubirwamo bihagije.

Ibikoresho byihuta bya kamera bikunda kugaragara kumurongo wumukara iyo bifotowe, cyangwa igipimo cyumukara ntigihagije, kandi ibara ryamabara ntirihuye.

Hamwe niterambere ryikoranabuhanga ryabashoramari IC bakora, habaye intambwe mubibazo bitatu byingenzi kandi ibyo bibazo byakemuwe.
Mugukoresha progaramu ntoya ya LED yerekanwe, kugirango tumenye neza ko umukoresha yorohewe igihe kirekire, urumuri ruto kandi rwinshi-rwinshi ruba urwego rwingenzi rwo kugerageza imikorere yumushoferi IC.

Driver IC nuguhuza umuzenguruko munini muri chip ntoya kugirango ikore, kugirango imbaraga zumuzunguruko zerekana amashusho ya LED zimaze kunozwa neza, IC nziza ya HD kugeza HD LED yerekana ubwiza bwa videwo, Amabara afite ingaruka zikomeye zo kubona. Kugirango umenye inshuro nyinshi zo kugarura ubuyanja, ibyamamare IC ikunzwe gukoreshwa ni: MBI5153, ICN2163, SUM6086, nibindi.

 Kugeza ubu ICN2153 ikura vuba ku isoko, nayo irahagaze neza ariko ku giciro gito ugereranije na MBI5153.

MBI5153 ikomoka kuri Macroblock, ni chip ya shoferi ya LED yerekana amabara yose. S-PWM ikoreshwa mukugabanya guhindagurika kwishusho.

Iyinjiza ishusho yamakuru ikoreshwa muguhindura urumuri rwa LED ya ecran. Ubushyuhe bwo gukora ni -40 kugeza kuri dogere selisiyusi.

ICN2153 ikomoka kuri Chip ya mbere. Byakoreshejwe kuri videwo ntoya ya LED yerekana amashusho meza cyane yo kurwanya.

Ingaruka ntoya-imvi imwe ntabwo ihindurwa na PCB.

Irashobora guhindura ibyasohotse kandi ikagenzura neza urumuri rwa HD LED yerekana.

Iyerekana ryakemuwe neza. Ibara rito-imvi, kimwe namabara, gushushanya, nibindi birashobora gukoreshwa numurongo uwo ariwo wose kugirango ukureho imyuka mibi.

 YONWAYTECHkuyobora byerekanwe nkumushinga wabigize umwuga, burigihe dukunda buri cyizere cyizerwa kubakiriya bacu, 1920hz-3840hz igipimo cyo kugarura ubuyanja hamwe na 14bit-16bit ya ecran yo gukoresha murugo cyangwa hanze birashobora guhitamo.
