LCD Display modules are readily available and they are dirt cheap (< $2 typically). They come in different "resolutions" typically expressed as number of characters and number of lines. Common ones are 1602 (16 characters in 2 lines) and 2004 (20 characters in 4 lines).
The modules are interfaces by an 8 bit parallel data bus (can be operated in 4 bit mode) and 4 control signals:
