When the TV screen is in a screen such as the Home screen, it switches over to the screen saver in a short time. (OLED TV)

To protect the TV from image retention, a screen saver is activated if operations aren't performed for a while.
The screen saver is cancelled and returns to the previous screen when the remote control is operated.

For Android TV™ models, the screen saver run time can be changed with the following procedures.
