The typical Judo scoreboard has three information areas; an area for the White contestant’s score and penalties, an area for the Blue contestant’s score and penalties and an area for the contest time and osaekomi time.

If the score is tied after regulation, Golden Score period (overtime) starts immediately after regulation.  The Golden Score time period is unlimited with the next score winning the match.  Local tournaments often have a maximum Golden Score time period.  Consult your local tournament rules.  The following video joins a match in progress and shows the match going to Golden Score.
