Problems solved by technology
[0005] The purpose of the technical solution of the present invention is to provide a circuit alignment assembly and a display device, which is used to solve the problem of the prior art when the flexible substrate provided with an output pad is attached to another substrate to realize the connection of the output pads of the two. The flexible substrate is very thin and easily deformed, and is susceptible to small dimensional changes due to force, resulting in the misalignment of the output pads on the flexible substrate and the output pads on the attached substrate, making the circuit unconnected

Embodiment Construction
[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0035] In order to solve the problem in the prior art flexible panel manufacturing process, due to the deformation of the flexible panel, the Pad on the flexible panel and the Pad on the COF are misaligned to make the circuit unconnected during COF binding, and a circuit alignment component is provided, wherein The circuit alignment component can be formed as a flexible panel provided with a pad, or as a COF provided with a pad. By improving the arrangement of the pads on the flexible panel and / or COF, the binding between the flexible panel and the COF can be solved. The misalignment of the Pad on the flexible panel and the Pad on the COF makes the circuit unconnected.
[0036] It can be understood that the circuit alignment component described in the em...

The present invention provides a circuit alignment assembly and a display device, wherein the assembly includes: a flexible substrate; a plurality of output pads arranged on the substrate, and the plurality of output pads are arranged at intervals along a direction perpendicular to a preset central line; And there is a pitch between the output pad and the adjacent output pad, which is the distance between the output pad and the adjacent output pad in the direction perpendicular to the preset centerline and the distance between the adjacent output pads The sum of the widths; a plurality of output pads are respectively arranged on both sides of the preset center line, and among the multiple output pads located on one side of the preset center line, the first output pad and the adjacent second output pad The pitch between is smaller than the pitch between the third output pad and the adjacent fourth output pad, and the distance from the first output pad to the preset center line is smaller than the distance from the third output pad to the The distance from the preset centerline. When the alignment component is bonded to another substrate, the effect of improving the bonding precision of the output pads on the two substrates is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a circuit alignment component and a display device. Background technique [0002] Flexible display technology is a research hotspot in the field of display technology in recent years. It is widely used because of its advantages of lightness, lightness, good shock resistance and good impact resistance. At present, display devices made of flexible panels include: liquid crystal display devices, organic electroluminescent display devices and electrophoretic display devices, which can be applied to the production of smart cards, portable computers, and electronic paper. [0003] At present, the manufacturing process of flexible display devices has been greatly developed. Generally, the flexible panel is fixed on the glass substrate first, and then the backplane manufacturing process is carried out. This process is compatible with the existing liquid crystal display manufacturing equ...
