LED Erekana ubumenyi bwibanze

1. LED ni iki?
LED ni impfunyapfunyo yumucyo utanga diode. Ihame rya tekinoroji ya LED luminescence nuko ibikoresho bimwe na bimwe bya semiconductor bizatanga urumuri rwumurongo wihariye mugihe ikoreshwa. Ubu bwoko bw'amashanyarazi kugirango umucyo uhindurwe neza ni mwinshi. Imiti itandukanye irashobora gukoreshwa kubikoresho bikoreshwa kugirango ubone umucyo utandukanye. Kandi kureba inguni LED. Ni ecran yerekana inyandiko, ibishushanyo, amashusho, animasiyo, amagambo yatanzwe ku isoko, videwo, ibimenyetso bya videwo nandi makuru mugenzura uburyo bwo kwerekana disikuru yerekana urumuri rwinshi.

2. LED yerekana ecran irimo ubwoko bukurikira.

Ibara ryuzuye LED yerekana . Ibara ryuzuye naryo ryitwa amabara atatu yibanze, ntoya yerekana igice kigizwe namabara atatu yibanze yumutuku, icyatsi, nubururu. Ibara ryuzuye rya LED rikoreshwa cyane cyane kubibuga byindege, gariyamoshi, sinema, ahacururizwa no kuri stade.

Amabara abiri LED yerekana. Amabara abiri LED yerekana cyane cyane umutuku & icyatsi, umutuku & ubururu. Muri byo, umutuku & icyatsi nibisanzwe. Ibice bibiri byerekana amabara bikoreshwa cyane mubukungu, itumanaho, ibitaro, umutekano rusange, amazu yubucuruzi, imari n’imisoro.

Kugaragaza LED imwe. Ibara rimwe LED yerekana ifite umutuku, umuhondo, icyatsi, ubururu, umweru. Ibara rimwe LED yerekana ikoreshwa cyane cyane muri parike, aho imodoka zihagarara no mu maduka acururizwamo.

Hamwe no kuzamura imibereho, ibyo abantu bakeneye bikomeje kwiyongera. Ibara rimwe hamwe namabara abiri LED yerekanwe yagiye asimburwa buhoro buhoro LED yerekana.

3. Ibanze shingiro ryerekana.
LED yerekana ecran igizwe n'akabati ka LED (irashobora guterwa) n'ikarita y'abagenzuzi (ikarita yohereje n'ikarita yo kwakira). Kubwibyo, ingano ikwiye hamwe na kabine ya LED irashobora gukora ubunini butandukanye LED yerekanwe kugirango ihuze ibikenewe bitandukanye nibisabwa bitandukanye.

4. LED yerekana ibipimo rusange.
Imwe. Ibipimo bifatika
Ikibanza cya Pixel
Intera iri hagati yikigo cya pigiseli yegeranye. (Igice: mm)

Ubucucike
Umubare wa pigiseli kuri buri gice (ubumwe: utudomo / m2). Hariho isano runaka yo kubara hagati yumubare wa pigiseli nintera iri hagati ya pigiseli.
Inzira yo kubara ni, ubucucike = (1000 / pigiseli hagati).
Ubucucike bwaLED yerekana, isobanutse neza ishusho na ntoya nziza yo kureba kure.

Kubeshya
Gutandukana kutaringaniye kwa pigiseli na modul ya LED mugihe uhimba LED yerekana ecran. Uburinganire bwiza bwa LED yerekana ecran ntabwo byoroshye gutera ibara rya ecran ya LED kutaringaniza mugihe ureba.

Babiri. Ibipimo byerekana amashanyarazi
Igipimo cyijimye
Urwego rwumucyo rushobora gutandukanywa kuva mwijimye kugeza kumurika murwego rumwe rwurumuri rwa LED yerekana. Igipimo cyijimye nacyo cyitwa igipimo cyibara cyangwa ibara ryikigereranyo, bivuga urwego rwurumuri. Kuri tekinoroji yerekana ikoranabuhanga, ibara ryerekana ibintu byingenzi byerekana umubare wamabara yerekanwe. Muri rusange nukuvuga, urwego rwimyenda rwinshi, niko amabara agaragara, niko ishusho irushaho kuba nziza, kandi byoroshye kwerekana ibisobanuro birambuye.

Urwego rwimyenda rushingiye ahanini kuri sisitemu ya A / D ihinduka. Mubisanzwe bigabanijwemo ibara ryinshi, 8, 16, 32, 64, 128, 256 urwego nibindi, Iyo urwego rwinshi rwimyenda yerekana LED yerekana, ibara ryinshi, nibara ryiza.

Kugeza ubu, LED yerekana cyane cyane sisitemu yo gutunganya 8-bit, ni ukuvuga 256 (28) urwego rwimvi. Ubwumvikane bworoshye nuko hariho 256 umucyo uhinduka kuva umukara ugahinduka umweru. Ukoresheje amabara atatu yibanze ya RGB arashobora gukora amabara 256 × 256 × 256 = 16777216. Ibyo bikunze kwitwa amabara ya mega 16.

Ongera inshuro inshuro
LED yerekana LED yerekana ecran amakuru yamakuru agezweho.
Mubisanzwe, ni 25Hz, 30Hz, 50Hz, 60Hz, nibindi.

Ongera inshuro
LED yerekana yerekana inshuro amakuru yerekanwe inshuro nyinshi kumasegonda.
Mubisanzwe ni 960Hz, 1920Hz, 3840Hz, nibindi. Iyo igipimo cyo kugarura ubuyanja, niko ishusho yerekana neza. Iyo ufotora, igipimo gitandukanye cyo kugarura ibintu gifite itandukaniro rinini.

5. Erekana sisitemu
Sisitemu ya videwo ya LED igizwe nibice bitatu, isoko yerekana ibimenyetso, sisitemu yo kugenzura no kwerekana LED.
Igenzura sisitemu nyamukuru ibikorwa ni ibimenyetso byerekana, guhinduka, inzira, kohereza no kugenzura amashusho.
Led ecran yerekana ibikubiye mu kimenyetso.
