DESC: The VIERA TH-50PX500, TH-42PX500 and TH-37PX500 plasma TVs all feature Panasonics latest PEAKS (Picture Enhancement Accelerator with Kinetic System) technology incorporating a new plasma panel, deep black filter and real black drive system. The deep black filter attached to the front protection glass reduces light transmittance, effectively suppressing external glare and reflection. The real black drive system has realized a high contrast ratio of 3,000:1 in the dark environment, creating deeper and richer blacks.
