LED yerekana nigikoresho gikoresha diode itanga urumuri (LED) nkibintu bitanga urumuri kugirango berekane ibishushanyo, videwo, animasiyo nandi makuru ukoresheje ecran ya elegitoroniki. LED yerekana ifite ibyiza byo kumurika cyane, gukoresha ingufu nke, kuramba, kureba impande zose, nibindi, kandi ikoreshwa cyane mukwamamaza imbere no hanze, ubwikorezi, siporo, imyidagaduro yumuco nizindi nzego. Kugirango tumenye neza ingaruka zerekana no kuzigama ingufu za LED yerekana ecran, birakenewe kubara agace ka ecran nubucyo muburyo bukwiye.
1. Uburyo bwo kubara ecran ya ecran ya LED yerekana ecran
Agace ka ecran yerekana LED yerekana ubunini bwahantu hagaragara neza, mubisanzwe muri metero kare. Kubara agace ka ecran yerekana LED, ibipimo bikurikira bigomba kumenyekana:
1. Umwanya utudomo: intera iri hagati ya buri pigiseli na pigiseli yegeranye, mubisanzwe muri milimetero. Umwanya muto utudomo, niko hejuru ya pigiseli yubucucike, niko gukemura hejuru, kugaragara neza ingaruka, ariko nigiciro kinini. Akadomo k'akadomo muri rusange kagenwa ukurikije ibintu bifatika byerekana no kureba intera.
2. Ingano yicyiciro: buri module irimo pigiseli nyinshi, nigice cyibanze cya LED yerekana. Ingano ya module igenwa numubare wa horizontal na vertical pigiseli, mubisanzwe muri santimetero. Kurugero, module ya P10 isobanura ko buri module ifite pigiseli 10 itambitse kandi ihagaritse, ni ukuvuga pigiseli 32 × 16 = 512, naho ingano ya module ni 32 × 16 × 0.1 = 51.2 kwadarato.
3. Ingano ya ecran: Iyerekana rya LED yose ryerekanwe na modul nyinshi, kandi ubunini bwaryo bugenwa numubare wa horizontal na vertical modules, mubisanzwe muri metero. Kurugero, P10 yuzuye-ibara ryuzuye rifite uburebure bwa metero 5 nuburebure bwa metero 3 bivuze ko hari 50 / 0.32 = 156 modules mu cyerekezo gitambitse na 30 / 0.16 = 187 modules mu cyerekezo gihagaritse.
2. Uburyo bwo kubara umucyo wa LED yerekana
Umucyo werekana LED yerekana ubukana bwurumuri rusohora mubihe bimwe na bimwe, mubisanzwe muri buji kuri metero kare (cd / m2). Iyo urumuri ruri hejuru, niko urumuri rukomera, niko rutandukana, nubushobozi bwo kurwanya kwivanga. Umucyo muri rusange ugenwa ukurikije ibidukikije bifatika hamwe no kureba inguni.
1. Umucyo w'itara rimwe rya LED: ubukana bwurumuri rutangwa na buri tara rya LED, mubisanzwe muri millicandela (mcd). Umucyo w'itara rimwe rya LED ugenwa nibikoresho byayo, inzira, ibyagezweho nibindi bintu, kandi umucyo wamatara ya LED yamabara atandukanye nayo aratandukanye. Kurugero, urumuri rwamatara ya LED rutukura muri rusange ni 800-1000mcd, urumuri rwamatara rwatsi rwa LED muri rusange ni 2000-3000mcd, kandi urumuri rwamatara yubururu LED muri rusange ni 300-500mcd.
2. Umucyo wa buri pigiseli: Buri pigiseli igizwe namatara menshi ya LED yamabara atandukanye, kandi ubukana bwurumuri butangwa nayo ni igiteranyo cyurumuri rwa buri bara LED urumuri, mubisanzwe muri candela (cd) nkigice. Umucyo wa buri pigiseli ugenwa nuburinganire bwacyo nuburinganire, kandi umucyo wa buri pigiseli yubwoko butandukanye bwa LED yerekanwe nayo iratandukanye. Kurugero, buri pigiseli ya P16 yuzuye ibara ryerekana ibara rigizwe numutuku 2, icyatsi 1, nubururu 1 bwa LED. Niba 800mcd itukura, 2300mcd icyatsi, na 350mcd itara ry'ubururu LED ikoreshwa, umucyo wa buri pigiseli ni (800 × 2 + 2300 + 350) = 4250mcd = 4.25cd.
3. Umucyo muri rusange wa ecran: ubukana bwurumuri rwerekanwe na LED yose yerekana ni igiteranyo cyurumuri rwa pigiseli zose zigabanijwe nigice cya ecran, mubisanzwe muri candela kuri metero kare (cd / m2) nkigice. Muri rusange umucyo wa ecran ugenwa nigisubizo cyacyo, uburyo bwo gusikana, gutwara ibinyabiziga nibindi bintu. Ubwoko butandukanye bwa LED yerekana ecran ifite urumuri muri rusange. Kurugero, imyanzuro kuri kwadarato ya P16 yuzuye ibara ryuzuye ni 3906 DOT, naho uburyo bwo gusikana ni 1/4 gusikana, bityo ubwinshi bwayo bwerekana ni (4.25 × 3906/4) = 4138.625 cd / m2.
3. Incamake
Iyi ngingo itangiza uburyo bwo kubara agace nubucyo bwa LED yerekana ecran, ikanatanga formula hamwe nurugero. Binyuze muri ubu buryo, ibipimo bya LED byerekana birashobora gutoranywa ukurikije ibikenewe hamwe nibisabwa, kandi ingaruka zo kwerekana hamwe no kuzigama ingufu zirashobora kuba nziza. Birumvikana ko, mubikorwa bifatika, ibindi bintu bigomba kwitabwaho, nkingaruka zumucyo wibidukikije, ubushyuhe nubushuhe, gukwirakwiza ubushyuhe, nibindi kumikorere nubuzima bwa LED yerekana.
LED yerekana ni ikarita nziza yubucuruzi muri societe yubu. Ntishobora kwerekana amakuru gusa, ahubwo inatanga umuco, kurema ikirere no kuzamura ishusho. Ariko, kugirango tubone ingaruka ntarengwa zerekana LED, birakenewe kumenya uburyo bwibanze bwo kubara, gushushanya neza no guhitamo ecran ya ecran nubucyo. Gusa muri ubu buryo dushobora kwemeza kwerekana neza, kuzigama ingufu, kurengera ibidukikije, kuramba nubukungu.
