Light extraction efficiency of LED displays with perpendicular parallelepiped transparent optical cavities.
In this paper formulas are derived describing the light extraction efficiency of the transparent perpendicular parallelepiped optical cavities in LED displays. The efficiency is calculated for a mirror-wall cavity and for a cavity having walls formed by an air-epoxy interface. Results show that optical efficiencies of these cavities are almost identical and equal to approximately 13%.
