Panel
Panel	LED LCD	Plasma
Panel detail
Panel detail	Panasonic specifies an LED LCD panel with Local Dimming Ultra. AVForums identifies the reviewed 55-inch panel as IPS with full-array direct backlighting and 128 zones; that zone count is not claimed for the 65-inch size. Panasonic's 3000 Hz Backlight Scanning claim is not a native refresh rate.	Panasonic's UK TX-P42G20B, TX-P46G20B and TX-P50G20B manual specifies native Full HD NeoPDP plasma panels. The marketed 600 Hz sub-field drive is not the native image refresh rate, which remains unpublished.

Panasonic's second-generation NeoPDP panel, Intelligent Frame Creation, Resolution Enhancer and advanced white-balance, gamma and colour-management controls.

Motion handling

HDTVTest measured 900 lines of motion resolution with Intelligent Frame Creation off and 1080 with it on, but saw some ball shimmer during sports. It found 1080p/24 playback free of telecine judder. These are measurements of the reviewed 42-inch set, not a native refresh specification.
