Abstract: An illuminating circuit structure includes a film sheet, an illuminant, a printed baseline layer, and a printed pad layer. The printed baseline layer includes a first baseline segment and a second baseline segment printed on the film sheet, while the printed pad layer includes a first bar pad and a second bar pad. For a first baseline head of the first baseline layer and a first pad head of the first bar pad, one of which extends along a first direction and the other of which extends along a second direction not parallel to the first direction. Therefore, the first baseline segment and the first bar pad achieve electrical connection despite of an existed print shifting. Similarly, a second baseline head of the second baseline layer and a second pad head of the second bar pad also can achieve electrical connection despite of an existed print shifting.

Abstract: A printed circuit structure includes a printed conductive pattern and a printed conductive adhesive pattern. The printed conductive pattern includes a first wire and a second wire. One of a first main contact portion of the first wire and a first main contact portion of a first adhesive of the printed conductive adhesive pattern extends in a first direction, while another thereof extends in a second direction perpendicular to the first direction. With different lengths in the first direction, manufacturing errors between the first wire and the first adhesive in the first direction can be contained without affecting the connection in between. Similarly, a second main contact portion of the second wire and a second main contact portion of a second adhesive of the printed conductive adhesive pattern can also adopt the same design in the first direction to ensure the electric connection.
