Eggcrate display

An eggcrate display consists of a matrix of incandescent light bulbs. A foam rubber mask with an array of holes surrounding the bulbs is attached to the display, causing it to resemble an egg crate.
Some eggcrate displays use a complete 5×7 matrix for each digit, permitting the display of nearly all alphanumeric characters. Other types display only numeric characters and optionally a dollar sign. This type of egg-crate display is popularly used for sports scoreboards.
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, game shows that used eggcrate displays have switched to either plasma or liquid crystal displays in the 2000s and beyond, as shows began switching to high-definition broadcasts.
