Abstract

In the front structure of a flat-panel display, a Teflon-AF (amorphous fluoropolymer) layer is sandwiched between the glass and the ITO layer to reduce the total reflection of light from the denser glass to the air. The light transmittance through this Teflon-AF sandwiched sample was measured using both a photometer with scattered laser light as its light source and a luminescence meter with a mercury-free flat discharge lamp as its light source. An enhancement of the transmitted light was observed with both measurements. With the mercury-free flat discharge lamp, an enhancement of more than 60 % was observed. The Teflon-AF sandwiched structure appears to be a viable method to increase the coupling-out efficiency of flat panel displays.
