Abstract
Description
Technical Field
[0001] The utility model relates to the field of display technology, in particular to a component patch structure, an FPC and a display module with an optimized design of a component area. Background Art
[0002] In the design of FPC, in order to ensure that components can be accurately mounted, patch selection positions need to be reserved in the component area. The design of these reserved positions is to adapt to the possible deviations in the automated patching process, ensuring that the components can be correctly aligned and firmly pasted on the FPC.
[0003] See Figure 1 , in some display modules for multiple application scenarios, patch selection positions for a one - in - two circuit are reserved in the FPC component area 1. The one - in - two circuit needs to reserve two patch selection positions 2, that is, the two parallel circuits of the one - in - two circuit are respectively arranged in the two patch selection positions 2. Among them, the common terminals 31 of the two parallel circuits are arranged at intervals, resulting in the two patch selection positions 2 being likely to exceed the range of the FPC component area 1 required by the customer, causing interference with the overall structure of the terminal product to be matched.
[0004] In response to this, it is necessary to adopt a more refined layout design and use smaller components, but this may involve changing the component model or choosing a more compact package form, which conflicts with the set process requirements. Therefore, there is an urgent need for a solution to compress the area of the patch selection position area without changing the component model. Summary of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a component patch structure, an FPC and a display module with an optimized design of a component area. By optimizing the connection mode of components, the patch area is reduced, so that the components can be correctly aligned and firmly pasted on the FPC, preventing the patch selection position from exceeding the required range of the FPC component area and avoiding interference with the overall structure of the terminal product to be matched.
[0006] The technical solution adopted by the utility model is as follows:
[0007] The utility model provides a component patch structure with an optimized design of a component area, including an FPC component area, in which one or more patch selection positions are provided. The component is a one - in - two circuit, and there is no gap between the common terminals of the two parallel circuits of the one - in - two circuit, so that one of the one - in - two circuits is arranged in each of the patch selection positions; the common terminal is a shared connection line or a shared connection point respectively connected to the two parallel circuits.
[0008] As a further improvement of the above - mentioned technical solution:
[0009] There is no gap between the common terminals of the two parallel circuits of the one - of - two circuit, and its structure is that the two parallel circuits share a common terminal.
[0010] There is no gap between the common terminals of the two parallel circuits of the one - of - two circuit, and its structure is that the common terminals of the two parallel circuits are stacked vertically.
[0011] Conductive adhesive is provided on the contact surface where the common terminals of the two parallel circuits are stacked vertically for bonding.
[0012] Welding is performed on the contact surface where the common terminals of the two parallel circuits are stacked vertically.
[0013] The FPC component area is rectangular, and the multiple patch selection positions are arranged at intervals along the length direction of the rectangle.
[0014] The width of the patch selection position is not greater than the width of the FPC component area.
[0015] Multiple FPC component areas are provided.
[0016] The present utility model also provides an FPC, including the component patch structure with optimized design of the component area.
[0017] The present utility model also provides a display module, including the above - mentioned FPC.
[0018] The beneficial effects of the present utility model are as follows:
[0019] Since there is a common terminal in the one - of - two circuit, in the prior art, the common terminals of the two circuits in the one - of - two circuit are usually arranged at intervals, resulting in occupying two patch reserved positions, and the width of the two patch reserved positions is likely to exceed the preset component area. The present utility model creatively overlaps the common terminals of the one - of - two circuit or only sets one common terminal for the two circuits to share, reducing the space of the patch reserved positions, avoiding the patch exceeding the FPC component area, thus meeting the component area limit requirements of the terminal whole machine and avoiding the structural interference problem of the whole machine.
[0020] The present utility model solves the problem of insufficient space in the component area without changing the component model or packaging form, on the basis of meeting the existing set process requirements, with simple structural design and good effects.
[0021] Other features and advantages of the present utility model will be described in the subsequent specification or understood by implementing the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS
