1. Menene LED?
LED shine takaitaccen diode haske mai fitar da haske. Ka'idar fasahar hasken haske ta LED ita ce wasu kayan semiconductor za su ba da haske na takamaiman tsawon lokacin da aka yi amfani da halin yanzu. Irin wannan wutar lantarki zuwa haske yadda ya dace yana da girma sosai. Ana iya yin magunguna daban-daban akan kayan da ake amfani da su don samun haske iri-iri. Kuma duban kusurwa LED. allo ne wanda ke nuna rubutu, zane-zane, hotuna, rayarwa, zance na kasuwa, bidiyoyi, siginar bidiyo da sauran bayanai ta hanyar sarrafa yanayin nuni na diodes masu fitar da haske na semiconductor.
2. LED nuni fuska hada da wadannan iri.
Nunin LED mai cikakken launi . Cikakken launi kuma ana kiransa launuka na farko guda uku, ƙaramin nuni wanda ya ƙunshi manyan launuka uku na ja, kore, da shuɗi. Ana amfani da allon LED mai cikakken launi a filayen jirgin sama, tashoshin jirgin ƙasa, gidajen sinima, manyan kantuna da matakai.
Dual launi LED nuni. Nunin LED mai launi biyu yana da ja & kore, ja & shuɗi. Daga cikin su, ja & kore sun fi yawa. Ana amfani da nunin launi biyu a cikin kuɗi, sadarwa, asibitoci, tsaro na jama'a, manyan kantuna, kuɗi da haraji.
Nuni LED guda ɗaya. Nunin LED mai launi ɗaya yana da ja, rawaya, kore, shuɗi, fari. Nunin LED mai launi ɗaya ana amfani dashi a wuraren shakatawa, wuraren ajiye motoci da shagunan sayar da kayayyaki.
Tare da inganta yanayin rayuwa, bukatun mutane na ci gaba da karuwa. Launi guda ɗaya da nunin LED masu launi biyu a hankali an maye gurbinsu da cikakkun nunin LED masu launi.
3. Ainihin abun da ke ciki na nuni.
Allon nunin LED ya ƙunshi kabad ɗin LED (ana iya raba) da katin masu sarrafawa (katin mai aikawa da katin karɓa). Sabili da haka, mai kula da adadin da ya dace da ɗakunan katako na LED na iya yin nunin nunin LED daban-daban don saduwa da buƙatun yanayi daban-daban da buƙatun nuni daban-daban.

Girman launin toka
Matsayin haske wanda za'a iya bambanta daga mafi duhu zuwa mafi haske a daidai matakin haske na nunin LED. Hakanan ana kiran sikelin launin toka ko sikelin launin toka, wanda ke nufin matakin haske. Don fasahar nunin dijital, sikelin launin toka shine mahimmin abu don adadin launuka da aka nuna. Gabaɗaya magana, mafi girman matakin launin toka, mafi kyawun launuka masu kyau, mafi kyawun hoto, kuma yana da sauƙin bayyana cikakkun bayanai.
Matsayin launin toka ya dogara da tsarin jujjuyawar A/D. Gabaɗaya an raba shi zuwa babu launin toka, 8, 16, 32, 64, 128, 256 matakan da sauransu, Mafi girman matakin launin toka na nunin LED, mafi kyawun launi, da launi mai haske.
A halin yanzu, nunin LED yana ɗaukar tsarin sarrafa 8-bit, wato, matakan launin toka 256 (28). Fahimtar mai sauƙi shine cewa akwai canje-canjen haske 256 daga baki zuwa fari. Amfani da manyan launuka uku na RGB na iya samar da launuka 256 × 256 × 256 = 16777216 launuka. Wato ana kiransa da launukan mega 16.
Sabunta mitar firam
LED nuni LED nuni allo bayanai update mita.
Gabaɗaya, shine 25Hz, 30Hz, 50Hz, 60Hz, da sauransu. Mafi girman mitar canjin firam, mafi kyawun ci gaban hoton da aka canza.
Sake sabuntawa
Nunin LED yana nuna adadin lokutan da aka sake nuna bayanan a kowane daƙiƙa guda.
Yawanci shine 960Hz, 1920Hz, 3840Hz, da dai sauransu. Mafi girman adadin wartsakewa, mafi kwanciyar hankali nunin hoton. Lokacin hoto, ƙimar wartsakewa daban-daban yana da babban bambanci.
5. Tsarin nuni
Tsarin bangon bidiyo na LED ya ƙunshi sassa uku, tushen sigina, tsarin sarrafawa da nunin LED.
Babban aikin tsarin sarrafawa shine damar sigina, juyawa, tsari, watsawa da sarrafa hoto.
Allon jagora yana nuna abun ciki na tushen siginar.
