Display device i.e. analog bar display unit, for use in motor car for realizing analog bar graph depending on input signal, has control electronic unit varying radiation power to vary expansion of illuminated surfaces on display region
The device (1) has light sources (3) e.g. LEDs, and a display region (A) that is rearwardly illuminated by the light sources. A control electronic unit is arranged for the light sources for varying light radiation power of the light source depending on an input signal to vary expansion of illuminated surfaces (L1-L4) on the display region. The illuminated surface is observed with an eyelet, and the light sources are arranged in such a manner that illuminated surfaces of the light sources on the display region are partially overlapped to each other.
