— Temporal response is one of the major concerns for liquid‐crystal‐display (LCD) performance. Fast response time is preferred for high‐fidelity image rendering. Several methods have been proposed to improve the LCD temporal performance. A method to assess the impact of temporal responses based on measured or modeled device temporal characteristics with a contrast‐sensitive computational observer that is intended to predict human performance is reported. A method to compare different devices and temporal blur reduction approaches has been applied. It was found that slow temporal response of the display device greatly affects signal contrast and observer performance. This methodology, after validation with human observers, could be used to compare different displays with different inter‐gray‐level transition time profiles.
