Second the comment, "STM32 NOT really designed for Lcd drive."
Recall that Lcds do not like DC. Should/when you "turn it off" your
AC scan will be lost - resulting in DC bias which will "kill" your Lcd in time. (you thus extend your product from pedom. to "new art")
Several chip makers offer scanned Lcd ICs. (Maxim) Review of their data may spark some ideas. In the stone age we used 74C4543 "official" Lcd digit driver. You may be able to model its output or keep these "alive" while the STM32 sleeps...

what's the problem with sleeping the processor after each half cycle? would it still use too much power?
Retrieving data ...
