or removably fastened to the idt referring now to fig3 and 4 the emi faceplate assembly 20 has a 34 honeycomb 34 grid 22 formed from a plurality of similar hexagonal emi optical pipes such as optical pipe 24 of fig4 which extend outwardly from the idt display surface 14 and divide the display surface into discrete elements that is each emi optical pipe defines and is associated with a discrete and selectively illuminated element or pixel of the display surface each optical pipe 24 has an outer casing or wall 26 as shown by fig4 that is formed from a suitable metal which is a good electrical conductor each optical pipe 24 contains a transparent optical medium such as an optically clear plastic that forms an optical core 28 which is encased by the outer casing 26 this encased optical core is the functional equivalent of a fiber optic conductor and enhances the transmission of visible light originating from an associated illuminated pixel in the idt display 14 the encased optical pipe 24 channels the light in accordance with the known light pipe effect somewhat like the light enhancement principle of image intensifiers in prior art night vision devices it is contemplated and should be understood that other frequencies in the electromagnetic spectrum in addition to visible light could also be transmitted through these optical pipes 24 of the grid 22 in fig5 similar optical pipes 24 are clustered in the honeycomb grid 22 of the emi faceplate assembly 20 with the outer wall 26 of each.
