Digital Photo Frames

Near the beginning of the 20th century, two new types of display monitors began to receive mainstream acclaim, LCD (Liquid Crystal Display) and PDP (Plasma Display Technology) commonly referred to as just ‘Plasma’.  These two technologies provide a high definition image on the monitor (whether it be a television, computer, or small device), but do so through different means.  Plasma technology involves an inert mixture of noble gases held between two glass panels, through a complex process involving the gases being turned into plasma the monitor emits light and can display an image.  LCD technology involves tiny pixels arrayed in front of a light source, that then light up at various intensities to create the image. 

In general, LCD technology produces a higher quality image, but LCD monitors are also much more expensive.  LCD technology is also much more common in small devices than Plasma technology.  You might find an LCD digital picture frame, an LCD alarm clock, or a GPS device with an LCD display, while Plasma tends to be more restricted to televisions and computer monitors.
