Panasonic uses its own unique image-analysis technology. This technology converts the motion in each scene into data, and each frame is virtually displayed in a shorter length of time, to create crisp images.Content stored in an SD card or USB memory stick can easily be played on VIERA's large screen. A wealth of customisation functions let you add background music and effects.Panasonic is committed to making our products more friendly to the environment. In line with this commitment, all VIERA plasma display panels are free of both lead and mercury. This reduces the impact on the environment years down the road when the TV is recycled or retired from use. Plasma VIERA displays are self-illuminating, so their viewing angle is wider, and there are no differences in brightness throughout the screen.VIERA automatically controls itself and the devices connected to it according to the usage conditions. The user doesn't even have to think about it. VIERA uses power only when it is needed and uses it efficiently for dramatic energy savings.
