Abstract
Abstract An LED bar graph display is disclosed, which can simultaneously display signal strength and diagnostic information. When an input signal is received, the indicators are selectively operated to display a strength value of the input signal. When a diagnostic condition occurs, the indicators are selectively operated to display the diagnostic condition. Thus, the LED bar graph display performs the dual functions of displaying signal strength and diagnostic information.
