- the display device includes a display panel and a flexible circuit board bonded together. Both the display panel and the flexible circuit board include a bonding area and an overlapping terminal located in the bonding area. The overlapping terminal of the display panel and the flexible circuit board are overlapping. The terminals are butted with each other to achieve electrical connection between the two. In the bonding process, the bonding area of the components that need to be bonded is heated and pressed through a pressure head, so that the overlapping terminals of the display panel and the flexible circuit board will be crimped together through conductive glue.
- the display panel and the flexible circuit board may expand due to heat, which increases the width of the overlapping terminals and the gap between the overlapping terminals, causing the corresponding overlapping terminals to be offset or dislocated, or even unable to overlap each other. connection, eventually leading to poor driver performance of the display device.
- the area and transverse size of the overlapping terminals (along the direction in which the overlapping terminals are arranged, such as the extension direction of the first reference line described below) of the overlapping terminals can be increased by arranging the overlapping terminals to be inclined. Reduce the chance of poor overlap between overlapped terminals.
- the central axis of the bonding area (perpendicular to the overlapping terminal row) is directly The direction of the cloth) is used as a reference line to design parameters such as the arrangement position and degree of inclination of the inclined lap terminals, and at the same time, the position (affecting the length) and width of the traces connected to the lap terminals are adjusted to adjust the lap.
- the display device may face changes in shape, add other components and set up corresponding control circuits, reconstruct the structural layout, etc., resulting in the need to offset the area where the bonding area is located. Avoid other circuit structures (such as the connectors below). In this case, there will be varying degrees of offset between each lap terminal and the corresponding trace. That is, there are some lap terminals and corresponding traces. The connection distance between lines becomes smaller, and the connection distance between some overlapping terminals and corresponding traces becomes larger.
- the arrangement position of the lap terminals is still designed based on the central axis of the bonding area, and the arrangement and width of the traces need to be changed, that is, the traces need to be Redesign, which will greatly increase the design and manufacturing costs of the entire display device.
- the bonding structure includes a bonding area.
- a plurality of overlapping terminals are provided in the bonding area, and the overlapping terminals are arranged in at least one row.
