Abstract

A display apparatus capable of displaying a plurality of alpha-numeric characters includes a display device (2) comprising a matrix of picture elements disposed in a plurality of rows and columns and means for activating selected combinations of the elements to display a full range of alpha-numeric characters. All, or substantially all of the characters are each displayed in a sub-matrix occupying only 5 rows and 5 columns of the matrix of picture elements.
