STM32L0538-DISCO - GDEY0213B74 - refresh time

[XIBiyotee]

Hi,

I bought an STM32L0538-DISCO MB1143B for an internal project.

This is the first time i work with an e-paper and i am surprised by the refresh time of the display which is slower than i expected and could be an issue.

I observe the refresh time of the display is highly dependant of the temperature:

• 100° = 2.1s
• 25° = 2.1s
• 15° = 3.1s
• 10° = 6.4s

Could you confirm that is a "standard" refresh time for an e-paper ?

Apart from temperature is there another way to reduce the refresh time ?

Best Regards,

Welcome @XIBiyotee, to the community!

The display in the STM32L0538-DISCO is from 2012, in the meantime considerably better and faster e-paper displays have appeared on the market.

However, the e-paper displays usually have their own controller, so that the refresh times of displays are determined exclusively by themselves and their controllers. These times can therefore only be influenced by selecting the appropriate display, not by the STM32 supplying the data.
