You've got a BCD count coming off your logic and a 7-segment display that's expecting decoded segments. The 4056 sits between them and does the translation. Feed in BCD, get out the right segments lit. No lookup tables, no microcontroller overhead for a simple readout. One chip, $5, and your display actually shows the number
