Description:
FIELD OF THE INVENTION  
         [0001]    This invention relates generally to electronic devices and more specifically to placing switches under electronic displays.  
         BACKGROUND OF THE INVENTION  
         [0002]    Electronic displays may be found on digital cameras, cell phones, wristwatches, GPSs (Global Positioning Systems), and many other digital devices. Included in the electronic displays available for use are LCDs (Liquid Crystal Displays) and OLED (Organic Light Emitting Diode) displays. Portable electronic devices usually are small. As a consequence, the area on these devices is used very carefully. Each function placed on a portable electronic device should be useful and take up as little space as possible. Functions that may be combined in the same space may help to increase the utility and reduce the size of a portable electronic device. Digital cameras are an example of a portable electronic device that requires space and function to be used carefully.  
           [0003]    Digital cameras come in forms small enough and versatile enough to perform almost all of the tasks that conventional cameras can perform, and they can do other things that conventional cameras cannot. The digital camera is ideal for creating pictures that you can e-mail or post on the Internet.  
           [0004]    The digital camera can be used much like a conventional film camera. Most digital cameras have more in common with automatic point-and-shoot cameras than they do with professional SLR cameras. They generally have auto-focus, and they can adjust for brightness, shutter speed and aperture automatically.  
           [0005]    The “film” of a digital camera is a removable media-storage device (floppy disk, Flash memory card, etc). As with a film camera, you simply replace the storage device when it&#39;s full and continue to take pictures. The difference is you don&#39;t need to develop digital pictures. You can download them directly to your computer and they are ready to use.  
           [0006]    As with film cameras, one of the primary applications of images taken by digital cameras is creating prints. Many digital cameras now have resolutions comparable to 35 mm film. Furthermore, new ink-jet inks and papers can produce prints that surpass conventional silver-halide prints.  
           [0007]    If you take pictures in JPEG format at 640×480 resolution, you can download them to your computer and e-mail them to friends without having to do anything to the picture. This eliminates most of the steps you would need to take to do this with a film camera: There&#39;s no need to get film developed or scan the developed picture. Just take the picture, transfer it to the computer and e-mail it.  
           [0008]    The files that you create with your digital camera can also be posted to the Web. If you have a personal home page, you can display your pictures there. Another good use of the digital camera is taking pictures of things you would like to sell. A digital camera can save you a lot of time and money if you often sell things in online auctions because you can take a picture of an object and post it to the auction site very quickly and without having to pay for film or developing. If you&#39;re selling a house or car, you could also post pictures on the Web to help potential buyers see what they are getting.  
           [0009]    Many digital cameras contain an electronic display to view an image before taking a photograph. In addition, an electronic display may be used to review photographs taken previously. Many digital cameras have 2 or more “arrow” buttons on the back of the camera next to an electronic display. The arrow buttons are used to navigate through images, menus, and other functions on the digital camera. These arrow buttons work well, but they may result in the camera looking complex, the electronic display being smaller than desired, and the camera being difficult to grip without pressing a button.  
           [0010]    There is a need in the art to reduce the area required for arrow buttons and electronic displays. One embodiment of this invention place switches, which act as arrow buttons, under a rocking electronic display. Another embodiment places a transparent cover over a visual display such that the flexible edges of the cover may be pressed to activate switches located under the cover. These innovations clean up and simplify the layout of electronic devices with little, if any, reduction in functionality. A detailed description of these embodiments of this invention is described later.
