Image-Persistence Cause & Prevention

Image-Persistence is rare on LCDs but is something of which you, the customer, should be aware.

What is Image-Persistence?

A residual image from a previous screen is still viewable after changing channels/inputs. Sometimes the after image will fade away in a few seconds/minutes, but it is possible that the image is persistent and doesn’t fade away. This problem is most common on devices that use phosphor in the screen, but can also affect LCDs. Although Image-Persistence takes longer to happen on LCDs than with phosphor based displays, care should be taken to prevent permanent effects. Image-Persistence is also known as “Image Burn-In”, “Image-Retention”, and “Image-Sticking”.

What causes Image-Persistence on LCDs?

When an LCD TV or monitor is operated continuously for a long period of time with a fixed (non- moving) image, a trace of electric charge can build up near electrodes inside the LCD module. The result of this is a residual image of the previous image when the screen is changed.

How do I prevent Image-Persistence on my LCD?

•Turn the device off when not use.

•Do not leave static DVD or game menus on the screen for long periods of time.

•Use a screen saver and/or power save feature when using the LCD as a PC monitor.

•Change your PC’s background wallpaper periodically.

How do I reverse Image-Persistence on my LCD?

•Leave the device off for several hours/days.

•Display a white image on your screen for several hours/days.

•Use a screen saver that uniformly “exercises” each part of the screen. NOTE: These methods do not guarantee that image burn-in will be reversible.

Is Image-Persistence covered by warranty?

No, this is considered misuse and is not covered by warranty. Normally, only product defects are covered by warranty and Image-Sticking is inherent to the technology used to make the display.
