DETAILED DESCRIPTION In view of the foregoing disadvantages inherent in the known types of keyboard templates now present in the prior art, the present invention provides an improved display keyboard.
As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved display keyboard which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a conventional keyboard having an upper edge, lower edge, and pair of side edges.
Also included is a plurality of function keys comprising of a standard CTRL key, SHIFT key, CAPS LOCK key, ENTER key, and ALT key situated on the keyboard with conventional indicia situated thereon.
A plurality of display keys are also situated on the keyboard.
Each display key has a liquid crystal display, light emitting diode display, or any future state of the art display invention situated thereon for depicting alphanumeric characters and indicia.
Finally, for controlling the operation of the present invention, a conventional computer is connected to the keyboard and adapted to depict via the display keys characters and indicia relevant to the function of the key during a current software application.
To prevent confusion and eliminate clutter, the display keys that are not relevant to the software are rendered blank.
The computer is further adapted to display via the display keys characters the specific executable task associated with the combination of depressing one of the ALT, CTRL, or SHIFT keys simultaneously with one of the display keys.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.
