Conclusion

It is important to note the effect of APL on a monitor's performance. Average pixel level (APL), indicates the measure of light output of a given image as a percentage of the light output of a full white image. An average television signal has an APL of 20%, implying 20% of all the pixels are at full capacity, or all the pixels are at 20% capacity, or some kind of combination. Weber argues that the energy usage of a PDP with an APL of 20% is actually slightly better than an LCD monitor (2004).

Therefore it is necessary to factor the application of the monitor when determining ideal performance. Websites or computer applications with a high APL would be best viewed on an LCD monitor. LCDs resistance to image retention also make it the better choice for computer use. Television viewing and theater-like settings would be best served by a plasma display panel because of their high contrast ratio and ability to handle motion blur.

Both LCDs and PDPs are available in several resolutions, most commonly 1080p. Lifespan is also said to be exactly even, at about 60,000 hours, or 20 years at 8 hours a day (CNET.com 2009). Measuring the pros and cons of each format ultimately results in a tie. In the end you have to review the facts and make the decision for yourself.
