Abstract
A panel circuit structure for transmitting electrical signals to an active area is provided. The panel circuit structure includes a first transmission pad, a first test pad, a second transmission pad, a second test pad, and a third transmission pad, which are connected to a driving element. The first transmission pad, the first test pad, the second transmission pad, and the second test pad transmit electrical signals to the active area via the first transmission lines and second transmission lines. The first transmission pads and the second transmission pads are disposed at a first end of the driving element while the third transmission pad is disposed at a second end of the driving element. The first and second test pads are disposed outside the coverage area of the driving element.
Claims11
A panel circuit structure, comprising:
- a substrate;
- a plurality of first transmission strings disposed on the substrate, wherein each of the plurality of first transmission strings includes:
- a first transmission pad;
- and
- a first test pad electrically coupled with the first transmission pad;
- and
- a plurality of second transmission strings disposed on the substrate, wherein at least a part of the plurality of first transmission strings is spaced parallel to the plurality of second transmission strings, each of the plurality of second transmission strings includes:
- a second transmission pad;
- and
- a second test pad electrically coupled with the second transmission pad,
- wherein each of the plurality of second transmission pad and the corresponding second test pad is disposed between the first transmission pads and the first test pads of the adjacent first transmission strings, the second transmission pad is closer to the first transmission pad than the second test pad is.
A panel circuit structure, comprising:
- a first transmission row including a plurality of first transmission pads;
- a second transmission row being parallel to the first transmission row and including a plurality of second transmission pads, wherein each of the second transmission pads is disposed between two corresponding adjacent first transmission pads;
- a second test row parallel to the second transmission row, the second test row and the first transmission row are respectively disposed on two opposite sides of the second transmission row, the second test row including a plurality of second test pads, and each of the second test pad corresponding to and electrically connecting to each of the second transmission pads;
- and
- a first test row parallel to the first transmission row, the first test row and the second transmission pads respectively disposed on two opposite sides of the second test row, the first test row including a plurality of first test pads, wherein each of the first test pads is disposed between the adjacent second test pads and is electrically connected to each of the first transmission pads.
