The present invention relates to a packaging member for a display module, and more particularly, to a display module packaging member having a structure that can effectively absorb the external impact while packaging the display module in a stable manner, and a packaging assembly having the same.

Recently, as a device for displaying an image, a display panel using a liquid crystal display, a plasma display panel, or the like has a large screen, and has excellent characteristics of high quality, ultra-thin, light weight, and wide viewing angle. .

Before the display panel is manufactured as a final product sold to consumers, the display panel is generally modularized and shipped with signal transmission members such as a tape carrier package (TCP) and circuit parts mounted thereon.

FIG. 1 is a perspective view schematically illustrating a conventional structure for packaging a plasma display module, which is an example of the display module.

Referring to FIG. 1, in order to ship the plasma display module 10, a plurality of plasma display modules 10 have been erected upright and transported in a box-shaped container 90. However, when the plasma display module is disposed vertically as described above, since the load is concentrated along the side surface of the plasma display module, it is prone to breakage due to vibration or external impact and warpage occurs due to its own weight. have.

In order to solve this problem, a separate soft buffer member may be disposed in the container 90. However, since the space inside the container is reduced due to the buffer member, the loading space of the plasma display module is reduced, thereby reducing the number of plasma display modules loaded in one container. Therefore, not only the increase in cost due to the buffer member itself, but also the transportation cost of the plasma display module is increased.

In addition, since the buffer member is made of a soft material, hardness may be reduced. Therefore, in the case where a large outer shock of an appropriate level or more is transmitted to the shock absorbing member, the adverse effect of increasing the movement of the plasma display module due to poor hardness of the shock absorbing member appears. As a result, there is a risk that the circuit unit provided in the plasma display module or the signal transmission member disposed on the side of the module may fall or be damaged.

Therefore, there is a great need to develop a new packaging structure capable of increasing the loading rate while stably packing the plasma display module 10.

An object of the present invention is to provide a packaging member for a display module and a packaging assembly having the same having a structure that prevents load from being concentrated on the side of the display module due to its own weight.

In addition, an object of the present invention is to provide a packaging member for a display module having a structure capable of stably protecting the display module regardless of the impact strength of the outside and a packaging assembly having the same.

Accordingly, the packaging member for a display module in one aspect of the present invention comprises: an inner cushion portion having a plurality of first buffer parts protruding from the first edge so that the first edge portion and the side surface of the display module contact each other; It is made of a higher density material than the inner cushion portion, and includes a second edge portion coupled to the outside of the first edge portion, and at least one second buffer portion protruding from the second edge portion in the direction of the inner cushion portion.

2 is an exploded perspective view illustrating a display module packaging member 200 and a display module 300 accommodated therein according to a preferred embodiment of the present invention, and FIG. 3 is a view illustrating a display module 300 applicable to the present invention. An exploded perspective view showing an example. Referring to FIG. 2, the packaging member 200 includes an inner cushion part 210 and an outer cushion part 220, and wraps the display module 300 from the outside. The packaging member 200 and the display module 300 accommodated therein constitute the packaging assembly 100.

In this case, the display module 300 may be applied to various display modules such as a plasma display module and a liquid crystal display module, and FIG. 3 shows a plasma display module as an example of the display module 300. Referring to FIG. 3, the display module 300 includes a plasma display panel 310, a chassis 320, and a circuit unit 380.

The plasma display panel 310 implements an image by gas discharge, and includes a front panel 311 and a rear panel 312. The chassis 320 is disposed behind the plasma display panel 310 to support the plasma display panel 310.

The thermal conductive sheet 340 may be interposed between the plasma display panel 310 and the chassis 320. The heat conductive sheet 340 diffuses heat generated from the plasma display panel 310 to the surroundings. The plasma display panel 310 and the chassis 320 are fixed to each other using double-sided tapes 330.

A plurality of circuit units 380 are disposed behind the chassis 320, and circuits for driving the plasma display panel 310 are wired to the circuit units 380. The circuit units 380 are spaced apart from the rear surface of the chassis 320 at predetermined intervals.

Meanwhile, the circuit unit 380 is a plurality of driving units 381, 382, and 383 for driving sustain electrodes of the plasma display panel 310, and SMPS (Switching) as a pre-parking device for applying power to these driving units. Mode Power Supply) 384 may be provided.

 The circuit units 380 transmit an electrical signal to the plasma display panel 310 through signal transmission members. Such signal transmission members include a flexible printed cable (FPC), a tape carrier package (TCP), a chip on film (COF), and the like. The flexible circuit board 370 may be.

In addition, the plasma display module 300 may further include heat dissipation members 360 disposed to cover the flexible circuit boards 370. In the present exemplary embodiment, the heat dissipation member 360 discharges heat generated from the electronic elements 375 to the outside and prevents damage to the flexible circuit boards 370. As the display module 300 is accommodated in the packaging member, one packaging assembly 100 is completed, and these packaging assemblies 100 are stacked alone or in plurality, and are carried in a container.

4 is a cross-sectional view taken along line IV-IV of FIG. 2, and FIG. 5 is a plan view of the packaging assembly of FIG. 2 from above.

2, 4, and 5, the inner cushion part 210 includes a first edge part 211 and a plurality of first buffer parts 216. The first buffer unit 216 protrudes from the first edge unit 211 such that the side surface of the display module 300 is in contact with the first buffer unit 216. Therefore, the display module 300 may be arranged to be fitted to the first buffer unit 216, and when the shock occurs from the outside, the display module 300 moves to the left and right, and thus the first buffer unit having elasticity 216 is in contact with the display module 300 to absorb the shock. The first buffer unit 216 may continuously protrude side by side from the first edge unit 211 to the center of the display module 300 in an embossing shape, for example, and thus the display module 300 is horizontally formed. The shock absorber 216 may be easily fitted into the buffer unit 216, and the movement of the predetermined display module 300 may be prevented, thereby preventing the display module 300 from being damaged by an impact.

The outer cushion part 220 is made of a material of higher density than the inner cushion part 210. That is, for example, the density of the outer cushion part 220 may be 60 to 70 kg / m 3, and the density of the inner cushion part 210 may be 25 to 35 kg / m 3.

 The outer cushion portion 220 includes a second edge portion 221 and a second buffer portion 226. The second edge portion 221 is formed to surround the first edge portion 211 from the outside to support the first edge portion 211. The second buffer part 226 protrudes from the first edge part 211 toward the inner cushion part 210. That is, the second shock absorbing portion 226 has a shape in which a part is inserted into the inner cushion portion 210. As described above, the second shock absorbing part 226 is made of a harder member than the inner cushion part 210, and absorbs the shock of the display module 300 secondarily, and at the same time, more than necessary by the external shock. It is possible to prevent large movements from occurring in the display module 300. If a large movement occurs more than necessary in the display module 300, the flexible printed circuit board 370 (see FIG. 3) or the circuit unit 380 provided in the display module 300 and sensitive to the movement may be damaged, thereby transmitting a signal. This may not be right.

 The second buffer part 226 may protrude from the second edge part 221 so as to penetrate the first edge part 211 and be inserted into a part of the first buffer part 216. This may prevent the display module 300 from moving more than necessary more efficiently. In this case, the shape of the second buffer unit 226 and the volume ratio with respect to the inner cushion unit 210 may be determined by digging the degree of movement of the display module 300.

On the other hand, the first shock absorbing portion 216 may be formed to continuously protrude side by side from the first edge portion 211, thereby effectively distributing and absorbing the shock received by the display module 300 in all directions. .

Meanwhile, the outer cushion portion 220 and the inner cushion portion 210 may include at least one selected from the group consisting of expanded polypropylene (EPP), expanded polyethylene (EPE), and expanded polyurethane (EPU), and these have an impact absorption force. It is known as an excellent material. For example, the outer cushion part 220 may be formed of a high density EPP material, and the inner cushion part 210 may be formed of an EPP material having a lower density than the outer cushion part 220. In this case, the high density EPP material may have a density of 60 to 70 kg / m 3, and the low density EPP material may have a density of 25 to 35 kg / m 3.

On the other hand, the inner cushion 210 is preferably formed to have the same height as the display module 300 or higher than the display module 300. This is because when the display module 300 is accommodated in the packaging member 200, if a part thereof is exposed to the outside, the display module 300 may be easily damaged due to an external impact so that the display member 300 may not function as the packaging member 200. Because it becomes. In addition, the packaging member 200 is moved in a plurality of stacked state, because if the display module 300 is higher than the packaging member is exposed to the outside, it is not easy to stack another packaging member on the packaging member again. to be.

The packaging member 200 may further include a protection member 240 covering at least the circuit unit 380. That is, referring to FIG. 4, when the display module 300 is stacked on the packaging members 100 and transported to the outside, the display module 300 may shake up and down. Due to such shaking, a phenomenon in which the display module 300 stacked on the bottom collides with the display module 300 stacked on the top may occur. In particular, the shaking phenomenon occurs as the adjacent to the central portion of the display module 300. However, even if not disposed in the center of the display module 300, even if the circuit portion 380 with the highest height H from the chassis 320 shakes up and down with a small displacement, the circuit portion 380 is located at the top The possibility of colliding with the plasma display panel 310 of the displayed display module is increased. As such, when the plasma display panel 310 and the circuit unit 380 collide with each other, there is a risk of causing fatal damage to the plasma display panel 310. If the film filter is attached to the front surface of the plasma display panel 310, the film filter may be torn. However, since the protection member 240 covering the circuit unit 380 is disposed, the plasma display panel 310 is protected by preventing direct collision between the plasma display panel 310 and the circuit unit 380.

The protective member 240 is formed using a variety of materials, it is preferably formed of a material containing EPP (Expanded Polypropylene), EPE (Expanded Polyethylene), EPU (Expanded Polyurethane). However, the present invention is not limited thereto, and may be formed using plastic.

The protective member may be fixedly coupled to the chassis, and in this case, when the protective member 240 is formed of a conductive material, electromagnetic waves generated in the elements of the circuit part may be shielded.

Meanwhile, as shown in FIG. 3, the inner cushion part 210 may further include a module seating part 230. The module seating unit 230 is formed so that the outer periphery of the display module 300 is seated. Therefore, the inner cushion part 210 together with the first edge part 211 and the first buffer part 216 protruding from the first edge part 211 into the display module 300, the first edge part And a module seating portion 230 protruding further from the first buffer portion 216 into the display module 300 from the 211 and / or the first buffer portion 216. The module seating unit 230 may have the same shape as the display module 300. That is, for example, if the display module 300 is a rectangular shape, the module seating portion 230 may also be formed in a square shape. The module seating unit 230 functions to support the display module 300 from the lower side and at the same time absorbs the external shock when the external shock is transmitted to the lower side of the display module 300.

According to the packaging member 200 having such a structure, when a predetermined or less shock is transmitted from the display module 300 from the outside, the display module 300 has a predetermined movement and a soft inner cushion portion 210. As the contact time becomes longer and the impact energy transmitted to the inner cushion part 210 becomes larger, the inner cushion part 210 absorbs the shock of the display module 300 to protect the display module 300. In addition, when a predetermined or more shock is transmitted from the display module 300, the outer cushion part 220 prevents the display module 300 from moving more than a predetermined time, and thus, the display module 300 is soft due to the softness of the inner cushion part 210. ) Is moved more than necessary to prevent adverse effects on the circuit section or the flexible printed circuit board.

According to the packaging member of the present invention and the packaging assembly having the same, as described above, regardless of the amount of impact generated on the display module, it is possible to prevent the external shock and simultaneously maintain the movement of the display module at a predetermined level, and thus, among the display modules. It can prevent some damage or malfunction of the display module.

In addition, since the display module is horizontally accommodated in the packaging member, concentration of load on the side surface of the display module can be prevented.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
