Sub-field
A number of sub-fields overlap to depict the image in each frame. Panasonic 
technology detects movement in the image and reflects it in each individual sub- 
field to achieve smooth playback with minimal blurring.
What's Sub-field?
Plasma TVs express a single frame of an image by using multiple images, each 
having a different gradation.
These separate images are called sub-fields.
