Abstract

A keyboard extension for a removable, portable display device such as a cellphone that also functions to house the display device. The display device housing is shaped and sized to securely enclose the removable, portable display device. The keyboard extension may have keyboard housing panels that are substantially equal in size to the display device being removably housed. These keyboard housing panels ham be hingably connected so that in a first configuration, the keyboard extension may function as a portable display device holder, while in a second configuration it may function as a wirelessly connected, split, full size keyboard input to the portable display. The keyboard extension may also include a numeric keypad housing panel that may be hingably connected to either of the keyboard housing panels.
