Most if not all Plasma TVs have the strobing effect like a sub-70Hz refresh rate CRT TVs (If your eyes/visual processing of your brain are fast enough)... While most LCDs light is based on the cold cathod refresh rate... which is at a very high rate .... faster than any human can perceive... That said some older sharp lcd panels do use a low refresh rate cold cathod that has the strobing effect.

This strobing effect is not obvious to everyone.. as some people can stand a 60Hz refresh tv/crt.

Plasma still needs to charge at 50/60 or 72 (or others with some blanking time i suspect or the screen will suffer burn-in) times to produce a constantly lighted image just like crt phosphors needs to be charged by the electron gun.... If your brain/eyes can register/train to register frequency below 75Hz (like me) you will see strobing effect on plasma screens ... to me all plasmas screens I have observed do have strobing effect (minor on newer panels).

mean while lcd usually does not suffer strobing effect as the cold cathod backlight usually used very high frequency... above and beyond 100Hz..and pixel twisting has also evoled to be faster than 8ms (120Hz).. So at least to me LCD registers as a constant image without strobing and may suffer shadow effect for fast moving objects (on slower panels)....
