Past convictions

I recently learnt that Jurors and Judges are not informed of prior convictions during a trial, I found this rather astonsishing.

Should or should prior convictions be mentioned during a hearing?

So, if Dayshawn has been convicted six times for liquor store robberies in which he spraypainted a purple frog on the store's wall before he left, the jury shouldn't be told about this pattern of behavior?

Fascinating.
