The visual performance of TFTLCD and CRT displays with different pixel densities were measured using task-oriented tests and subjective measures of visual comfort and preferences. The effect of resolution on displayed letter legibility was measured. The legibility of letters increases with increasing pixel resolution. At a viewing distance of 50 cm, no significant differences were obtained in letter counting rate of mixed case letters with 16 acrmin x-height. At 50 cm viewing distance, some subject preference and improved visual comfort was obtained for the high resolution TFTLCD.
