Embodiment Construction

[0015] The main purpose of this application is to respectively set extensions outside the effective contact areas of the two connecting elements. The two extension parts overlap at least partially, and when one of the connection elements expands relative to the other connection element due to the uneven expansion of the two connection elements, the two extension parts abut against each other, thereby slowing down the continuous expansion of the connection elements, thereby improving the expansion of the two connection elements. The problem of alignment deviation caused by uneven expansion of the connecting elements ensures that the contact surfaces of the two are in full contact. In addition, this application only needs to add extensions to each connecting element, and there is no need to pre-shrink the value according to the expansion of each connecting element Design, so there is no need for a large amount of experimental data, the scheme is simple, and the feasibility is hig...

Abstract

The invention discloses a connecting component and a display device. The connecting component includes a first connecting component and a second connecting component, and an overlapping area when thetwo components are in surface contact is an effective contact area of the connecting component. The first connecting component and the second connecting component are provided with a first extendingpart and a second extending part, the first extending part and the second extending part extend outwardly from the effective contact area, when the first connecting component and the second connecting component are attached, the first extending part and the second extending part are arranged adjacent to each other, and the first extending part and the second extending part at least partially overlap along a line of sight direction of a cross section of the effective contact area. On the above basis, an alignment deviation problem caused by uneven expansion amounts of the two connecting components can be improved, the full contact of the contact surface of the two components is ensured, the scheme is simple, and the feasibility is high.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a connection component and a display device. Background technique [0002] Currently, the display device has two technologies for realizing electrical connection, COP (Chip On PCB, fixing IC on a printed circuit board) and COF (Chip On FPC, fixing IC on a flexible circuit board). Affected by factors such as material, manufacturing process (such as manufacturing tolerances) and machine environment (such as pressure and temperature), these two technologies are prone to poor binding problems, which are manifested as the contact surface of two connected components The electrical connection pad (pad) has misalignment, which leads to poor contact of electrical signals, or even short circuit or open circuit. Taking COF technology as an example, the substrate (wire) of the display panel and FPC (Flexible Printed Circuit, flexible circuit board), the substrate of the display...
