2.8“TFT LCD Display Usage suggestions

Avoid image retention: The black panel should not display static images for a long time. It is recommended to refresh the content every 2 minutes or use a black/dynamic screen saver.

Installation precautions: Ensure that the contact surface of the cable is clean and avoid excessive bending.
