LED Nuni 6 Key Technologies

Nunin lantarki na LED yana da pixels masu kyau, komai dare ko rana, rana ko ruwan sama, nunin LED zai iya barin masu sauraro su ga abubuwan da ke ciki, don biyan bukatun mutane na tsarin nuni.

Fasahar siyan hoto

Babban ka'idar nunin lantarki ta LED shine canza siginar dijital zuwa siginar hoto da gabatar da su ta tsarin haske.Hanyar gargajiya ita ce yin amfani da katin ɗaukar bidiyo hade da katin VGA don cimma aikin nuni.Babban aikin katin sayan bidiyo shine ɗaukar hotunan bidiyo, da samun adiresoshin mitar layi, mitar filin da maki pixel ta VGA, da samun sigina na dijital musamman ta hanyar kwafin tebur ɗin duba launi.Gabaɗaya, ana iya amfani da software don kwafi ko satar kayan masarufi, idan aka kwatanta da satar kayan masarufi.Koyaya, hanyar gargajiya tana da matsalar daidaitawa tare da VGA, wanda ke haifar da gefuna mara kyau, rashin ingancin hoto da sauransu, kuma a ƙarshe yana lalata ingancin hoton lantarki.
Dangane da wannan, masana'antun masana'antu sun haɓaka katin bidiyo mai sadaukarwa JMC-LED, ƙa'idar katin ta dogara ne akan bas ɗin PCI ta amfani da 64-bit graphics totur don haɓaka ayyukan VGA da bidiyo zuwa ɗayan, kuma don cimma bayanan bidiyo da bayanan VGA zuwa samar da wani superposition sakamako, baya karfinsu matsalolin da aka yadda ya kamata warware.Abu na biyu, samun ƙuduri yana ɗaukar yanayin cikakken allo don tabbatar da cikakkiyar haɓaka hoton Bidiyo, ɓangaren gefen ba ya da ban mamaki, kuma hoton yana iya ƙima da ƙima kuma an motsa shi don saduwa da buƙatun sake kunnawa daban-daban.A ƙarshe, ana iya raba launuka uku na ja, kore da shuɗi yadda ya kamata don biyan buƙatun allon nuni na launi na gaskiya.

Haɓaka launi na ainihi na ainihi

Ka'idar nunin cikakken launi na LED yana kama da na talabijin dangane da aikin gani.Ta hanyar tasiri mai tasiri na ja, kore da launin shuɗi, za'a iya dawo da launuka daban-daban na hoton da sake sakewa.Tsaftar launuka uku ja, kore da shuɗi za su shafi haifuwar launin hoton kai tsaye.Ya kamata a lura da cewa haifuwa na hoton ba haɗin kai ba ne na ja, kore da launin shuɗi, amma ana buƙatar wani wuri.

Na farko, ƙimar ƙarfin haske na ja, kore da shuɗi ya kamata ya kasance kusa da 3: 6: 1;Abu na biyu, idan aka kwatanta da sauran launuka guda biyu, mutane suna da takamaiman hankali ga ja a hangen nesa, don haka ya zama dole a rarraba ja daidai a cikin sararin nuni.Na uku, saboda hangen nesa na mutane yana mayar da martani ga lanƙwasa mara tushe na ƙarfin hasken ja, kore da shuɗi, ya zama dole a gyara hasken da ke fitowa daga cikin TV ɗin ta farin haske mai haske daban-daban.Na hudu, mutane daban-daban suna da damar ƙudurin launi daban-daban a ƙarƙashin yanayi daban-daban, don haka wajibi ne a gano maƙasudin haƙiƙa na haifuwa launi, waɗanda gabaɗaya kamar haka:

(1) Matsalolin ja, kore da shuɗi sun kasance 660nm, 525nm da 470nm;

(2) Yin amfani da naúrar bututu 4 tare da farin haske ya fi kyau (fiye da 4 tubes kuma, yawanci ya dogara da ƙarfin haske);

(3) Matsayin launin toka na launuka na farko guda uku shine 256;

(4) Dole ne a karɓi gyaran da ba na kan layi ba don aiwatar da pixels na LED.

Za a iya tabbatar da tsarin sarrafa hasken ja, kore da shuɗi ta hanyar tsarin hardware ko software na tsarin sake kunnawa daidai.
