| Zusammenfassung: | A display board assembly, which includes a start unit connected to an end unit with a variety of intermediate display units set in therebetween in a line. By means of color contrast and diaphaneity difference the symbols on the intermediate which show a certain meaning collectively can be clearly seen in the day. When in the dark, a photosensor automatically triggers the light emitting diodes of the intermediate display units to illuminate the symbols thereon. |
