Optique Transparence Design Sariyasenw
LED ɛkran jɛlenw ka kɛnɛya bɛ sɔrɔ fɔlɔ ni pixel labɛncogo kɛrɛnkɛrɛnnen ye ani yeelen-cikanw ye. Laadalata LED jiralanw bɛ ni pixel density caman ye, wa u bɛ datugu ni fɛnw ye minnu tɛ ye (i n’a fɔ epoyi walima silikɔni), o bɛ na ni kɛnɛya bɛɛ lajɛlen dɔgɔyali ye kosɛbɛ. Faan wɛrɛ fɛ, LED ɛkran jɛlenw bɛ baara kɛ ni "hollowed-out" walima "spaced-out" pixel structure ye, LEDw bɛ jɛnsɛn yɔrɔ min na matrix kɔnɔ substrat transparent kan. LEDw ni ɲɔgɔn cɛ danfara minnu bɛ yeelen tɛmɛ, o bɛ yeelen bɔli bɛɛ ɲɛ.Dilancogo suganditaw minnu bɛ kɛ tuma caman na, olu ye:
1. Hollowed-out PCB Design: Printed circuit board (PCB) bɛ baara kɛ ni hollowed-out walima gridded layout ye walasa ka dɔ bɔ balili la yɔrɔw la minnu tɛ{3}} yeelen bɔ.
2. Kɛrɛfɛ-LEDw bɔli: Aw bɛ baara kɛ ni kɛrɛfɛ-LED bɔli puwɛntiw ye walasa ka yeelen jira sira kɛrɛnkɛrɛnnen dɔ fɛ, ka kɔkanna balili dɔgɔya.
