The Plasma Display Key-Based Keyboard

Traditional computer keyboards force the user to use a one and only one set of characters for input. Disclosed is a description of a plasma display key-based keyboard, which contains a tiny plasma display in each key. This invention gives the user the option of using one of multiple sets of characters to be displayed on the keyboard. Advantages of this invention include the following:

- Software controlled switching of character sets for different languages
- Display of special characters, e.g. for mathematics and arcane computer languages
- Display of keyboard shortcuts for applications
- More elegant display of character sets whose size is greater than the number of keys, e.g. Chinese

A simplified architecture of display output involves a CPU outputting display instructions to a monitor, often with a graphics processor intermediating the instructions.

For each key in current keyboards, there exists one and only one character label. Some newer keyboards are backlit so the user may easily see them in the dark (this is a form of keyboard output, albeit primitive), but the constraint of one and only one character label per key still exists. This invention proposes a next evolutionary step in keyboard output in placing a tiny plasma display on each key, allowing the dynamic assignment of a character for every key. The following diagram compares each of these ideas:
