The amount and type of pixel defects on a small high‐density display were varied to find out how the defects alter visual performance. The effect of character weight on the decrements caused by pixel faults was of particular interest. Visual performance was examined by using the Pseudo‐text search task, and subjective evaluations of visual comfort and defect visibility were included. The results provide further evidence to the former finding that, even though noticed, a small number of defects do not decrease visual performance. Furthermore, increase in vertical thickness of the displayed characters reduces the decrements further.
