Hamwe nogutezimbere no gushyira mubikorwa LED yo mu nzu, birashobora kugaragara ko LED yerekana ikoreshwa cyane kandi ikanakoreshwa cyane muri command center, ikigo gikurikirana ndetse na studio.Ariko, uhereye kumikorere rusange ya sisitemu ya LED yerekana, iyi disikuru irashobora guhuza ibyo abakoresha bakeneye?Amashusho yerekanwa kuri LED yerekanwe arahuye nicyerekezo cyabantu?Izi LED zishobora kwihanganira inguni zitandukanye zifunga kamera?Nibibazo bigomba gusuzumwa kuri LED yerekanwe.Nyamara, ibara ryinshi nurufunguzo rwo kunoza urumuri ruto rwo kwerekana LED yerekana.Kugeza ubu, abaguzi bafite ibisabwa byinshi kandi bisabwa kugirango ubuziranenge bwibishusho byerekanwe, kandi ni ngombwa kandi cyane kuri ecran ya LED kugirango igere ku ngaruka za "umucyo muke, imvi nini".Nzakora rero isesengura ryihariye nkurikije urwego rwimyenda igira ingaruka kuri LED yerekana.
- Igipimo cy'imvi?
- Ni izihe ngaruka za graycale kuri ecran?
- Hariho uburyo bubiri bwo kugenzura urwego rwimyenda rwerekanwe.
1.Igipimo cy'imvi?
Urwego rwimyenda ya LED yerekanwa rushobora nanone kwitwa LED umucyo.Urwego rwimyenda ya LED yerekana urwego rwurumuri rushobora gutandukanywa kuva mwijimye kugeza kumurika murwego rumwe rwurumuri rwa LED yerekana.Mubyukuri, urwego rwimyenda rushobora nanone kwitwa halftone, ikoreshwa mu kohereza amakuru yishusho kumarita yo kugenzura.Urwego rwumwimerere rwerekana urumuri rwa LED rushobora kuba 16, 32, 64. Hamwe niterambere ryikoranabuhanga, 256 ubu rikoreshwa nabakora inganda zikomeye.Urwego rwimyenda ya LED yerekana ecran itunganyirizwa murwego rwa 16, 32, 64 na 256 rwa pigiseli ya pigiseli binyuze mu gutunganya matrix, kugirango ishusho yoherejwe isobanutse neza.Yaba monochrome, amabara abiri cyangwa ibara ryuzuye-ecran, kugirango yerekane amashusho cyangwa animasiyo, birakenewe guhindura urwego rwimyenda ya buri LED igizwe nisoko ya pigiseli yibikoresho.Ubwiza bwo guhinduka nibyo dukunze kwita urwego rwimvi.
Dore urutonde rwogusobanurira neza.Kurugero, niba umutuku wera ari 255 naho umutuku ugaragara ni 0, hari amabara 256.Niba ushaka kwerekana amashusho hamwe nibikoresho bimwe, ugomba gukoresha tekinoroji yohereza amabara 256.Kurugero, niba ibara ryibara ryikadiri muri videwo ritukura 69, naho LED yerekana ecran ifite urwego 64 rwimyenda gusa, ibara muri videwo yamabara ntishobora kugaragara mubisanzwe.Ingaruka yanyuma irashobora gutekerezwa, kandi birigaragaza-ko ishusho ari nziza kandi nziza.
Impanuro: Kugeza ubu, urwego ntarengwa rwerekana imiterere ya LED yerekana ni 256, izwi kandi nka 65536, idashobora kuvugwa nabi, kubera ko buri tara ryamatara ryamabara yuzuye ya ecran ya LED rigizwe namabara atatu ya RGB, ibara rimwe rifite imvi 256 urwego, kandi umubare wose ni 65536.2.
2.Ni izihe ngaruka za graycale kuri ecran?
Urwego rwimyenda ya LED ya elegitoronike nini yerekana ihinduka ryurwego rutandukanye hagati yibara ryijimye ryijimye.Mubisanzwe, ibara ryikigereranyo cyibisanzwe-bisobanurwa LED yerekana hagati ya 14bit na 16bit, hamwe nurwego rurenga 16384, rushobora kwerekana impinduka zirambuye zamabara yishusho.Niba urwego rwimyenda rudahagije, urwego rwamabara ntiruzaba ruhagije cyangwa urwego rwibara rwibara ntiruzoroha bihagije, kandi ibara ryishusho yakinnye ntirizerekanwa neza.Ku rugero runini, kwerekana ingaruka za LED yerekana ecran iragabanuka.Niba ishusho yafashwe hamwe na 1 / 500s shitingi ifite amabara agaragara, byerekana ko urwego rwimyenda ya ecran ruri hasi.Niba ukoresheje umuvuduko mwinshi wo hejuru, nka 1/1000 cyangwa 1/2s, uzabona amabara agaragara cyane, azagira ingaruka zikomeye kumashusho rusange.
3.Hariho uburyo bubiri bwo kugenzura urwego rwimyenda rwerekanwe.
Imwe ni uguhindura ibyagezweho, naho ubundi ni ubugari bwa pulse.
1. Hindura ikigezweho kinyura muri LED.Mubisanzwe, LED ituma itanga akazi gahoraho ka mA 20.Usibye kwiyuzuza LED itukura, igipimo cyimyenda yandi LED iragereranijwe cyane cyane numuyoboro unyuramo;
2. Ubundi buryo ni ugukoresha inertie igaragara yijisho ryumuntu kugirango umenye igenzura ryumukara ukoresheje uburyo bwo guhinduranya impiswi, ni ukuvuga buri gihe guhindura ubugari bwumucyo (ni ukuvuga cycle cycle).Mugihe cyose uruziga rwamatara rwasubiwemo ari rugufi bihagije (nukuvuga igipimo cyo kugarura ubuyanja kiri hejuru bihagije), ijisho ryumuntu ntirishobora kumva urumuri rusohora pigiseli ihinda umushyitsi.Kuberako PWM ibereye cyane kugenzura ibyuma bya digitale, hafi ya LED zose zikoresha LED zikoresha PWM kugirango igenzure urwego rwimvi uyumunsi mugihe microcomputer zikoreshwa cyane mugutanga ibyerekanwa bya LED.Sisitemu yo kugenzura LED ubusanzwe igizwe nagasanduku gakomeye ko kugenzura, ikibaho cyo gusikana no kwerekana no kugenzura ibikoresho.
Agasanduku nyamukuru kagenzura kubona amakuru yumucyo ya buri bara rya pigiseli ya ecran kuva ikarita yerekana mudasobwa, hanyuma ikayigabana ku mbaho nyinshi zo gusikana.Buri kibaho cyo gusikana gifite inshingano zo kugenzura imirongo myinshi (inkingi) kuri ecran ya LED yerekana, kandi kwerekana no kugenzura ibimenyetso bya LED kuri buri murongo (inkingi) byoherezwa muburyo bukurikirana.
Kugeza ubu, hari uburyo bubiri bwo kohereza ibimenyetso byerekana ibimenyetso:
1. Imwe ni ukugenzura hagati yurwego rwimyenda ya buri pigiseli point kumwanya wo gusikana.Ikibaho cyo gusikana cyangirika cyurwego rwimiterere ya buri murongo wa pigiseli kuva kugenzura agasanduku (ni ukuvuga ubugari bwa pulse modulasiyo), hanyuma ikohereza ikimenyetso cyo gufungura buri murongo wa LED kuri LED ihuye muburyo bwa pulse (1 niba ari yaka, 0 niba idacanwa) muburyo bwa serial uburyo bwo kugenzura niba yaka.Ubu buryo bukoresha ibikoresho bike, ariko ubwinshi bwamakuru yatanzwe muburyo bukurikiranye ni bunini.Kuberako mukuzenguruka kumurika inshuro nyinshi, buri pigiseli ikenera impiswi 16 kurwego 16 rwimvi na 256 impiswi kurwego 256 rwimvi.Bitewe nigikoresho gikoresha inshuro nke, ecran ya LED irashobora kugera kurwego 16 rwimvi.
2.Imwe ni ubugari bwa pulse.Ikibaho cyo gusikana ibintu bikurikirana ntabwo ari ikimenyetso cyo guhinduranya buri LED, ahubwo ni 8-biti binini binini.Buri LED ifite moderi yubugari bwayo kugirango igenzure igihe cyo kumurika.Muri ubu buryo, mukuzenguruka kumurika inshuro nyinshi, buri pigiseli ikenera gusa impiswi 4 kurwego 16 rwimvi na 8 impiswi kurwego 256 rwimvi, bikagabanya cyane inshuro zikurikirana.Hamwe nubu buryo bwo kwegereza ubuyobozi abaturage ibara rya LED, 256 urwego rwimyenda irashobora kugerwaho byoroshye.
Hano hari urukurikirane rwinshi rwa ecran mubyumba MPLED yageze kumurongo wijimye wa 16bit, nka ST Pro, WS, WA, nibindi, bishobora kwerekana neza ibara ryumwimerere ryamashusho na videwo.Mugihe cyo gufotora byihuse, ibara ryavuzwe haruguru ntirishobora kugaragara.Ibyerekanwa bikozwe mubikoresho byo mu rwego rwo hejuru, nibicuruzwa byo mu rwego rwo hejuru mu nganda.Dutanga ubunini butandukanye bwa pigiseli intera yubunini, kimwe nibisubizo bitandukanye byumushinga.Niba ukeneye kugura icyiciro cya ecran ntoya mugihe gito, nyamuneka twandikire, umuyobozi wa serivisi iyobowe na serivisi imwe–GUSHYIRA MU BIKORWA.
