Abstract

A keyboard assembly includes a wireless USB (Universal Serial Bus) based keyboard having an upper face on which push buttons are movably mounted. A recess is defined in the upper face of the keyboard. A display is sized to be received in the recess. The display may be fixed in the recess. Alternately, the display is pivoted to the keyboard and movable between an erected position for user'"'"'s observation and a stowed position where the display is received in the recess. The keyboard and the display are controlled by a common USB interface control circuit thereby enabling the keyboard to receive and display video signals without additional circuit.
