| 摘要 |
An electronic sign using an LED is provided. The present invention comprises a multi-layered substrate in which an insulation layer is interposed between a conduction layer for a first electrode and a conduction layer for a second electrode; a plurality of LED elements inserted and fixed along display lines of a display part printed on a background sheet temporarily fixed on the substrate, wherein a first and a second lead terminal of the LED elements have different lengths, the first lead terminal of the LED elements is inserted and fixed into the conduction layer for the first electrode while being electrically connected to the conduction layer for the first electrode, and the second lead terminal of the LED elements, which is longer than the first lead terminal, passes through the electrode layer for the first electrode and the insulation layer and is inserted and fixed into the conduction layer for the second electrode while being electrically connected to the conduction layer for the second electrode such that the LED elements, spaced at regular intervals, are installed along the display lines of the display part. |
