Abstract
A compact keyboard for entry of alphanumeric data or other characters into a computerized system. A character formation key on the keyboard is formed by a plurality of bars which are capable of being activated for providing light. These bars are arranged in a mosaic pattern with several of the bars forming an outer box pattern and several of the bars extending inside of the box pattern. Light is emitted from each bar when such bar is in an activated lit condition. Each of the bars is switchable between an activated lit condition and an off condition, with the activated bars emitting light so as to display an alphanumeric character. The keyboard has a data entry mechanism for causing the displayed alphanumeric character to be entered into a computerized system.
