Abstract

Operator interaction with electrical systems is facilitated by providing electromechanical control devices, which have switch buttons, rotary knobs or the like, with flat panel displays that convey information pertaining to the controls that can be changed instantly by a display controller. The display may identify the function of the control, the current setting, create calibration marks or provide other graphics. The images change automatically if the same control is used for multiple functions. In one form of the invention, the display screen has openings in the image area and the controls extend through and protrude from the screen enabling display of graphics in close proximity to the controls. In another form, the settings of controls which are secured to the face of a display screen are optically or magnetically detected by sensors located behind the screen. In still another form of the invention, the display is embedded in a switch key and has an image area that is substantially coextensive with the key. This enables permanent markings, such as are found on computer keyboard keys for example, to be replaced with changeable images that identify multiple functions of the keys.

Claims

1. In a radio having a plurality of station selector switches each having a button which may be depressed to select a particular station and having means for enabling a user of the radio to condition each button for selection of a particular station that is chosen by the user, the improvement comprising a plurality of flat panel display screens for generating visible images, each of said screens forming at least a portion of the front surface of a separate one of said buttons, and control means for causing each of said screens to display indicia which identifies the user chosen station that is selected by depression of the particular button.

2. The apparatus of claim 1 wherein said radio has a control for switching between AM and FM reception, and wherein said control means changes said indicia which are displayed at said front surface of each of said buttons in response to operation of said control.

3. The apparatus of claim 1 wherein said control means causes the flat panel display screen at each of said buttons to display the call letters of the particular station that is selected by depression of the button.

4. The apparatus of claim 1 wherein each of said display screens displays indicia which are defined by activating particular image pixels within an array of image pixels, the image pixels being activated by energization of busbar conductors of a first layer of parallel busbar conductors and a second layer of parallel busbar conductors within said display screen wherein busbar conductors of the first and second layers extend in orthogonal directions within said screen.
