Eggcrate displays have been used on many game shows to display contestants' scores and / or for countdown clocks because other types of displays, such as LED seven-segment displays, were prone to being washed out by bright studio lights.

Though they continued to see extensive use well into the late 1990s, many shows began adopting LCDs in the 2000s.

They have also been used as variable-message signs on highways, although they were later superseded by flip-disc, fiber optic, and eventually LED displays.
