Image sticking is a phenomenon where a faint outline of a previously displayed image remains visible on the screen when the image is changed. To prevent image sticking on the Surenoo SLG320240A2 Series Graphic LCD Module, follow these recommendations:

1. Avoid operating the module with a fixed image on the screen for more than 2 hours.
2. If the monitor is operating in an elevated temperature environment, image stick can occur in as little as 30 minutes. Adjust your screen saver settings accordingly.
3. Power down the module during prolonged periods of inactivity, such as when a store is closed or during a shift when the module isn't used.
4. Use a screensaver with a black or medium gray background that is automatically set to come on if the module is inactive for more than 5-10 minutes.
5. Avoid placing the module in poorly ventilated areas or areas that will create excess heat around the module.
6. When defining icons, buttons, or windows on the screen, try to utilize block patterns instead of distinct lines as borders for dividing the display into distinct areas.
7. If it is necessary to display a static image, use colors that are symmetric to the middle gray level at the boundary of two different colors, and slightly shift the border line once in a while.
8. Utilize medium gray hues for areas that will have prolonged display times or remain static as other menu elements change.

If image sticking does occur, it can be reversed by running the screen in an "all black" pattern for 4-6 hours. It is recommended to do this in an elevated temperature environment of approximately 35º to 50ºC. Utilizing a dynamic screen saver with an all black background during prolonged idle display periods is also a good way to avoid image retention issues.

Please note that image sticking is considered normal operation for Graphic Display technology, and it is not covered by the Surenoo RMA warranty. Following the above recommendations will help minimize the occurrence of image sticking.
