Regarding the issue of the ESL price tag automatically refreshing the screen

E-papers will experience redness within 24 hours, with red particles swimming upwards, this is a physical phenomenon in E-Paper.

To prevent the ESL tags from turning red, we have set a 24-hour automatic refresh for our tags to ensure all tags always maintain a perfect background and display effect, refresh takes only a few seconds to complete and does not affect the customer's shopping experience.

And supermarkets usually update prices after it is closed, the refreshes will also occur at this time point 24 hours later.

We can also set a specific time for refreshing in our software, such as updating all price tags at 2am, then tags will automatically refresh at 2am every day.
