Yon ekran ekspozisyon ki ap dirije se yon aparèy ekspozisyon ki konpoze de dyòd ki emèt limyè -(LED) kòm inite pixel. Lè yo kontwole eta limen / koupe oswa chanjman koulè nan chak dirije, li dinamik prezante enfòmasyon tankou tèks, imaj, ak videyo. Pou pwodwi yo mansyone pi wo a, tanpri klike anba a pou aprann plis sou espesifikasyon yo.
Based on the electroluminescence effect of semiconductor materials-when current passes through the LED chip, electrons and holes recombine, releasing energy and emitting visible light in the form of photons. Depending on the pixel pitch (i.e., the distance between the centers of adjacent LEDs), LED displays can be divided into three categories: small pitch (≤2.5mm), standard pitch (2.5-10mm), and large pitch (>10mm), apwopriye pou ekspozisyon segondè -definisyon andedan kay la, pèfòmans etap, piblisite deyò, ak lòt senaryo, respektivman.
