What is Image Persistence?
Like the burn-in on CRTs, image persistence on LCD monitors is caused by the continuous display of static graphics on the screen for extended periods of time. What this does is cause the LCD crystals to have a memory for their location in order to generate the colors of that graphic. When a different color is then displayed in that location, the color will be off from what it should be and instead have a faint image of what was previously displayed. This problem is most common for elements of the display that do not change. So items that are likely to generate a persistent image are the task bar, desktop icons and even background images. All of these tend to be static in their location and will be displayed on the screen for extended period of time. Once other graphics are loaded over these locations, it may be possible to see a faint outline or image of the previous graphic.
