Basically they intend to flash the backlight at field rate to make motion sharper. By 'scanning' I guess they mean to flash tubes 1-8 in sequence from top to bottom to match the scanning row-based refresh of the LCD.
This will make the refresh more 'CRT like' and should improve motion sharpness - but the issues are increased flicker (like a CRT) and reduced backlight luminance (due to reduced duty cycle).
Perhaps they will allow the user to select between sharp motion mode (flashing backlight) and flicker-free mode (backlight always on). That way, if sharp motion mode is dimmer - you could select it when viewing in a darkened room.
It would be cool to see a true 100Hz / 120Hz LCD with flashed backlight using Philips Natural Motion to create the intermediate frames. Then we might finally see an LCD that can equal or surpass the dynamic picture quality of a CRT.
