Dangantakar da ke tsakanin nisan kallo da tazara na nunin LED an san shi da filin pixel. Fitar pixel yana wakiltar tazara tsakanin kowane pixel (LED) akan nuni kuma ana auna shi cikin millimeters.
Doka ta gabaɗaya ita ce ƙimar pixel ya kamata ya zama ƙarami don nunin nunin da aka yi niyya don a duba su daga nesa kusa kuma ya fi girma don nunin nunin da aka yi niyyar kallo daga nesa mai nisa.
Misali, idan an yi niyyar kallon nunin LED daga nesa kusa (a cikin gida ko a aikace-aikace kamar alamar dijital), ƙaramin ƙaramin pixel, kamar 1.9mm ko ƙasa, na iya dacewa. Wannan yana ba da damar haɓaka ƙimar pixel mafi girma, yana haifar da mafi kyawun hoto da cikakken hoto idan aka duba kusa.
A gefe guda, idan an yi niyyar kallon nunin LED daga nesa mai nisa (manyan nunin tsari na waje, allunan talla), an fi son girman girman pixel. Wannan yana rage farashin tsarin nunin LED yayin kiyaye ingancin hoto mai karɓuwa a nisan kallo da ake sa ran. A irin waɗannan lokuta, ana iya amfani da fitin pixel daga 6mm zuwa 20mm ko ma fiye.
Yana da mahimmanci don nemo ma'auni tsakanin nisa kallo da filin pixel don tabbatar da ingantaccen ƙwarewar gani da ingancin farashi don takamaiman aikace-aikacen.
Dangantakar da ke tsakanin nisan kallo da farar nunin LED an ƙaddara ta musamman ta ƙimar pixel da ƙuduri.
Girman pixel: Girman pixel akan nunin LED yana nufin adadin pixels a wani yanki, yawanci ana bayyana su a cikin pixels kowane inch (PPI). Mafi girman girman pixels, mafi girman pixels akan allon kuma mafi kyawun hotuna da rubutu. Matsakaicin nisan kallo, mafi girman girman pixel da ake buƙata don tabbatar da tsabtar nuni.
· Resolution: Ƙaddamar nunin LED yana nufin jimlar adadin pixels akan allon, yawanci ana bayyana su azaman nisa pixel wanda aka ninka da tsayin pixel (misali 1920x1080). Maɗaukakin ƙuduri yana nufin ƙarin pixels akan allon, wanda zai iya nuna ƙarin daki-daki da hotuna masu kaifi. Nisa nisan kallo, ƙananan ƙudurin kuma zai iya samar da isasshen haske.
Don haka, mafi girman girman pixel da ƙuduri na iya samar da ingantacciyar ingancin hoto yayin kallon nesa ya kusa. A tsawon nisa na kallo, ƙananan ɗigon pixel da ƙuduri na iya ba da sakamako mai gamsarwa.
