Abstract
The digital display apparatus comprises a board having one or more seven-element digital-type displays marked thereon. A flap is provided for each of the elements and is pivotable from a first position in which the associated element is exposed, to a second position in which it covers its associated element. Selective pivoting of the flaps enables each display to form any required digit.
