The PT-RZ570 Series features technology that directly modulates laser power output, enabling high contrast while reducing power consumption. Digitally controlled frame-by-frame scene-linking modulation ensures precisely adjusts light output, achieving accurate 20,000:1 contrast even when bright and dark scenes suddenly or frequently interchange. This unique Panasonic circuit optimizes the sharpness of each image based on the super high, high, medium, and low frequency components of the extracted image information. The resulting images are expressed with natural realism.
