ABSTRACT
ABSTRACT: Current standards regarding image quality of flat panel displays are usually lack of the involvement of customers. Therefore, the perceived image quality from customers was the focus of this study. While the classification of pixel faults of ISO 13406-2 standard was reviewed, an eyetracking experiment was conducted to understand the distribution of gaze duration on the screen. Two 17-inch LCD computer monitors were used for displaying different levels of image quality in terms of various numbers and locations of bright-pixel defects to 30 subjects. Subjects made their preference comparisons between the two screens through a questionnaire. Results showed that the perceived image quality was decreased as the number of defects was increased, and as the defects were near the central area of the screen. A partial interaction effect was found between the number and the location of defects. The findings of this study reveal that the location of defects should be taken into account along with the number of defects for the establishment of ergonomic image-quality requirements for the design and evaluation of flat panel displays.
