The use of bright and wide field-of-view (FOV) displays in future TV systems will enable us to enjoy TV programs with a rich sense of presence, i.e., a sense of “being there.” However, such displays can strongly stimulate human peripheral vision, which is sensitive to flicker. The recent widespread adoption of hold-type displays such as liquid crystal displays might circumvent the flicker problem in current TV systems. For temporal specification of future TV systems with bright and wide FOV displays, we measured the critical fusion frequency (CFF) in 26 participants, using varying luminance, duty ratios, and FOVs. We showed that CFF depended on the duty ratio and the FOV, and that more than 90 Hz was required to avoid flicker perception with wide FOV displays. Moreover, we demonstrated that flicker was regularly perceived in viewing wide FOV natural images presented at 60 Hz with a 50% duty ratio.
