[

Referring again to FIGS. 1 to 4, the connection part 120 electrically connects the plurality of electronic parts 111-113, and may be bent when a plurality of the electronic parts 111-113 flow.

For example, the connection unit 120 may include a flexible circuit board 121 for electrically connecting a plurality of electronic components 111-113 with a flexible material, at least one flexible circuit board 121 coupled to at least one surface of the flexible circuit board 121, And a reinforcing member 122 for preventing disconnection of the first electrode 121.

The flexible printed circuit board 121 has a flexible insulating member 121B and a plurality of electronic components 111-113 which are bonded to one region of the insulating member 121B and electrically And a conductive part 121A connected to the conductive part 121A.

Specifically, the insulating portion 121B has a thin film shape and can be flexibly bent. The insulating portion 121B may be a synthetic resin film made of an insulating material, for example, a polyimide (PI) film.

The conductive part 121A may be disposed in one area of the insulating part 121B in consideration of the electrical connection relationship with the plurality of electronic parts 111-113. The conductive portion 121A may be attached to the insulating portion 121B by high-temperature bonding or by an adhesive.

The conductive portion 121A may be made of a metal material having excellent electrical conductivity. For example, silver or copper may be used for the conductive portion 121A.

In the case of the flexible printed circuit board 121 (Flexible Printed Circuit Board), since the insulating portion 121B made of a flexible material is used, the flexible printed circuit board 121 can be bent to a certain extent and is used for miniaturized electronic products.

However, the flexible printed circuit board 121 has a problem that stress fatigue is accumulated due to repeated bending, or the flexible printed circuit board 121 is easily broken due to tensile force.

In order to enhance the tensile strength and the durability of the flexible printed circuit board 121, if the thickness of the polyimide film as the insulation part 121B is increased, the flexible printed circuit board 121 (Flexible Printed Circuit Board) There is a problem that flexibility is reduced.

Therefore, the embodiment solves this problem by using the reinforcing member 122 on one side of the flexible circuit board 121. [ Hereinafter, the reinforcing member 122 will be described.

The reinforcing member 122 may be coupled to at least one surface of the flexible circuit board 121. Specifically, the reinforcing member 122 may be bonded to one surface or both surfaces of the film-like flexible circuit board 121.

The reinforcing member 122 may be a flexible material that can be bent when the flexible circuit board 121 is bent. For example, the reinforcing member 122 may comprise at least one of a fiber, a nanofiber, and a carbon fiber, or a combination thereof.

The fibers can be divided into natural fibers and artificial fibers. The reinforcing member may comprise natural fibers and man-made fibers.

Natural fibers include plant fibers, animal fibers, and mineral fibers. Plant fibers include seed fibers such as cotton flowers, kapok cotton, and coir, and manila hemp and sisal There are animal fibers such as camphor fiber, camphor, jute, and hemp, and animal fibers include wool fibers such as wool, mountain wool, camel hair, cashmere, There are silk fibers (silk fiber) such as dogs and cats. And mineral fibers include asbestos (asbestos). The man-made fibers can be divided into inorganic fibers (organic fibers) and organic fibers (organic fibers).

Generally, the hexagonal rings of carbon have a structure in which a layered lattice is formed continuously, and the strength is 10 to 20 g / d and the specific gravity is 1.5 to 2.1. Therefore, carbon fiber is excellent in heat resistance, impact resistance, resistance to chemicals, resistance to pests, low specific gravity, high elasticity and rigidity.

The durability and tensile force of the flexible circuit board 121 can be improved without significantly decreasing the flexibility of the flexible circuit board 121 without significantly increasing the thickness of the flexible circuit board 121 if the reinforcing member 122 is made of a fiber material. The effect can be enhanced.

Specifically, the reinforcing member 122 made of a fibrous material can be bonded to the flexible circuit board 121 by an adhesive or thermo compression bonding. However, the present invention is not limited to this, and the reinforcing member 122 may be bonded to the flexible circuit board 121 by any method.

Since the reinforcing member 122 of the fiber material has excellent tensile strength and durability, it can be bonded to the flexible circuit board 121 in a mesh structure, thereby reducing the material cost of the reinforcing member 122.

As another example, the reinforcing member 122 may include a plurality of reinforcing frames 122A arranged horizontally with respect to the direction in which the restoring electronic components are disposed. Specifically, only the horizontal reinforcing frame 122A can be disposed in FIG.

 The reinforcing frames 122A and 122B may be disposed so as to overlap with the conductive portions 121A. A reinforcing frame 122A or 122B made of a fiber material may be disposed so as to overlap with the conductive portion 121A to prevent the conductive portion 121A from being damaged by durability and flexibility .

4, the conductive portion 121A is arranged in a direction in which a plurality of electronic components 111-113 are arranged, and the horizontal reinforcing frame 122A is arranged so as to overlap the conductive portion 121A do. The horizontal reinforcing frame 122A arranged to overlap with the conductive portion 121A can protect the conductive portion 121A and prevent cracking of the conductive portion 121A.

Of course, the number of the horizontal reinforcing frames 122A arranged to overlap with the conductive portions 121A may be larger than the number of the horizontal reinforcing frames 122A that do not overlap with the conductive portions 121A.

In addition, the embodiment may further include a connection housing 125 surrounding the connection portion 120.

The connection housing 125 is disposed to surround the connection portion 120 to protect the connection portion 120 from external impact and invasion.

The connection housing 125 may comprise a more flexible material than the housing segments 131-133. For example, the connection housing 125 may be made of a rubber material, and the housing slices 131-133 may be made of a synthetic resin material.

In addition, the connection housing 125 may further include a connection housing 125 having a bending groove 127 to facilitate bending.

The bent groove 127 provides a space in which the connecting housing 125 is bent in one direction.

Specifically, the bent groove 127 may be an inwardly recessed area on one side of the connecting housing 125. [

More specifically, the bent groove 127 may be formed in a direction opposite to the direction in which the liquid crystal display module 111 is exposed.
