Plasma 1 - LCD 0
According to Broadcast Engineering, Plasma is better than LCD for 3DTV background technology. One of the main differences between the two technologies, which has a definite impact on 3-D TV viewing, is processing speed. LCD technology has come a long way in increasing its refresh rate, with of 120Hz, 240Hz and even, some companies claim, 480Hz. However, plasma technology has never had an issue with motion blur.
With increased marketing efforts of LCD manufacturers to remove the stigma of slow refresh rates by touting ever-higher rate figures, plasma technology manufacturers have addressed refresh rate times by measuring processing speed. Major manufacturers claim processing speeds of up to 600Hz.
