Abstract
A method for automatically evaluating the displayed value comprises the steps of receiving data for display, exhibiting a display indication of the data on a light emitting diode display area substantially surrounded by a variable color background area, comparing the value of the data with a limit, and controlling color of the background area in accordance with the result of the comparison. A display device for automatically evaluating the displayed value includes a light emitting diode display area substantially surrounded by a variable color background area and a device for receiving data for display and for exhibiting them on the display area. A comparator compares the value of the data with a limit and accordingly develops a comparison signal which is used to control the color of the background area to automatically indicate the significance of the displayed data.
