The display itself is just called a seven-segment display. That type of display was probably the first type of numerical display used in calculators, watches etc. prior to the dot matrix display.
I don't know the name of the device used to assign places in line. It is an electronic display to show which number is being served in a "take a number" queing system,

Sounds like you already know; they are just dual 7-segment LED displays.
