43.3: How Fill Factor Affects Display Image Quality

Abstract

A psychophysical experiment was conducted to investigate the effect of field emission display (FED) fill factor on display image quality. A two‐alternative, forced‐choice psychophysical task was employed to obtain judgments of image coarseness and overall image quality as a function of three fill factors, 30 percent, 40 percent and 69 percent of VGA resolution FEDs. The results revealed that FED imaging performance is not improved by increasing the fill factor of 325 micron pixel pitch FEDs, provided that space‐average luminance is maintained constant.
