"In contrast to LCD displays, plasma televisions and CRT TVs have a virtually instantaneous response time.
This is mainly limited by the speed of their video processing engine rather than by the time it takes to fire the display phosphor; this is in the order of nano-seconds as against the milliseconds required for the liquid crystals to change state in LCD panels. In this respect, LCD panels still have a long way to go.
Yet, there is a further technical difference between the two technologies that renders plasma superior when it comes to pixel response time. Control of pixel intensity in a plasma display does not rely on the same drive process used in an LCD panel. In an LCD display, a minor adjustment in pixel intensity level is brought about by altering the drive signal in very small steps to adjust the twisting action of the liquid crystals, and which in turn controls the amount of light reaching the surface.
As we will soon explain in this article, this method of adjusting the drive voltage in an LCD panel in small increments to represent an intermediate intensity level, leads to a relatively slow response that is substantially slower than the full 'on' or 'off' states.
Instead, plasma replies on the pulsing of current - using time division multiplexing techniques (TDM). In other words, the pixel drive signal in a plasma display is either fully 'on' or fully 'off', and you simply adjust its duration using TDM to control the pixel intensity. This leads to a much faster pixel response in plasma displays."
