Abstract

One of the remaining disadvantages of Liquid crystal displays (LCDs) compared to CRT is the existence of motion blur. Motion picture quality of most of present LCDs is not adequate for high speed live images. There are two basic reasons for this: (1) the slow response time of LCs, and (2) the hold-type temporal rendering method of LCDs combined to the smooth pursuit eye movement of the human visual system. Conventionally the liquid crystal response time (LCRT) has been used as a quality parameter. However LCRT does not describe the perceived motion blur. To expressly describe motion blur, the response time of intermediate gray levels must be taken into account, and hence the index parameter Moving Picture Response Time (MPRT), for moving application has been defined recently.
