Many commercial digital signage deployments run almost continuously—sometimes 16 to 24 hours every day. Whether used in retail stores, restaurants, transportation hubs, self-service kiosks, or corporate information displays, static elements like logos, menus, and navigation bars often remain on screen for weeks or even months.
Although LCD technology is much more resistant to permanent burn-in than OLED displays, long-term static images can still lead to temporary image retention (image sticking), especially when displays operate at high brightness around the clock.
Here are several practices we've found useful for reducing image retention:
Rotate advertising content frequently instead of showing a single image all day.
Enable Pixel Shift if the display supports it.
Avoid placing logos in exactly the same position permanently.
Use animated backgrounds or subtle transitions instead of completely static layouts.
Reduce brightness to the level actually required for the installation environment.
Schedule automatic sleep or power-off periods during non-business hours whenever possible.
Design kiosk interfaces with auto-hide menus or periodically changing layouts.
Keep displays properly ventilated to avoid excessive operating temperatures.
For commercial deployments running 24/7, choosing displays specifically designed for continuous operation can also make a noticeable difference. Industrial and commercial TFT LCD modules generally include better thermal management and long-life backlight systems compared with consumer TVs.
We recently put together a more detailed technical guide covering the causes of LCD image retention and practical prevention methods for commercial digital signage systems. If anyone is interested, you can read it here:

I'm curious how everyone here manages long-running signage installations. Do you rely on Pixel Shift, content rotation, scheduled downtime, or other techniques to extend display life?
