ABSTRACT:
A bar and circular display or scale indicator utilizing a matrix of miniature incandescent lamps which individually illuminate closely stacked light transmitting segments forming closely spaced dot positions spaced along the length of the bar. The incandescent lamps are staggered throughout the length of the display with the light transmitting segments (fiber optics) directing light from the lamp source toward the center of the display, to present emitted light in a well defined line to which provide a linear or circular solid state display. The dot positions can be illuminated in any number of ways individually, sequentially or otherwise, depending on the selected mode of operation.
