I use ghosting to display a number and a spinner to indicate the unit is running....
When the device is half way finished the spinner reverses direction.

Have you got "interdigit blanking" ? You should have a brief, all-off state between digits.
Remember you only need to update at 24Hz for human vision to see a steady display.
