In this paper, we proposed a new driving scheme to reduce the motion blur and save the power for OLEDs(organic light emitting diodes). We adopted a DVS (dynamic voltage scaling) method to reduce power consumption and the division of TV field to improve motion blur. In the proposed scheme, BEW (Blur Edge Width) was decreased to the ratio of 1/4 compared to the conventional scheme under the optimal conditions. In this scheme, the gray levels to which the DVS method can be applied were divided into much smaller groups depending on the number of subfields. Therefore, our scheme does not guarantee less power consumption for every image compared to the conventional scheme. However, the new scheme can move the gray levels adopting the DVS to higher gray levels. Thus, we can save power even when having images at high gray levels.

We conducted visual perception experiments to determine the perception limits of motion blur based on human visual system at LCD TV's moving pictures. The motion blur can be expressed Blurred Edge Width (BEW). The results showed that the BEW of moving pictures should be below 3.4pixels (visual angle 4.2') at 3H distance in a living room environment.
