Abstract

With the consideration of Mura area and contrast, SEMI Standard provides a guideline for Mura inspection. However, for an end user, due to different tasks and environments, when interacting with a computer, Mura location on the screen may be an important factor affecting a user’s overall satisfaction with the LCD display. Regression analysis from this study showed that both Mura level and Mura location affect the perceived value of an LCD by a user. Further analysis showed that this perceived value may change across different Mura Level ranges. When Mura levels are high, the small correlation coefficient between markdown value of a display due to Mura and Mura location suggests that the display won’t be accepted by customers regardless of Mura location. On the other hand, if the Mura level is moderate, a higher correlation can be obtained, which means customers are sensitive to the Mura location.
