In particular, the side structure of the case top 410 is a dual structure including an inner extension portion 414 provided with a hook hole 412 and an outer portion 416 formed elongated along an edge thereof, and the outer portion 416 of the case top ) Is formed to extend long in the longitudinal direction of the case top, the inner extension part 414 is an extension blade piece formed with a certain width inside the outer part, and at the center of the inner extension part 414, the hook part of the connection holder ( A hook hole 412 is formed through which the 428 is caught.

On the other hand, the outer portion 416 of the case top 410 has a structure in which the front end is in contact with the front end of the side portion 326 of the cover bottom 320.

As a result, the outer surface of the side portion 326 of the cover bottom and the outer surface of the outer portion 416 of the case top 410 form a side outer portion of the display device or the entire set electronic device. There is no need for a front cover or a back cover.

That is, as the rear portion of the cover bottom 320 forms the rear of the display device or the entire set device, as shown in FIG. 5, there is no need for a back cover or a rear cover for a separate set device, and the outer surface of the side portion 326 of the cover bottom Since the outer surface of the outer portion 416 of the case top 410 is smoothly connected to form a side outer portion of the display device or the entire set electronic device, a separate front cover or middle cover is not required.

8 illustrates a process of assembling main parts of a display device according to an exemplary embodiment of the present invention.

A process in which the connection holder 400 used in the embodiment of the present invention is combined with the cover bottom 320 and the case top 410 is as follows.

First, the process of step 1 of temporarily assembling the connection holder 400 to the cover bottom 320 is performed. That is, in step 1, the cover bottom fixing hole 422 of the connection holder 400 is pressed into the holder coupling protrusion 322 of the cover bottom, and the elastic portion 424 of the connection holder is inserted into the elastic portion receiving groove 324 of the cover bottom. The connection holder 400 is set on the cover bottom by seating it inside.

In the state of this step 1, the connection holder 400 and the cover bottom 320 are not completely fixedly coupled, and thus can be viewed as a kind of temporary assembly state.

Next, step 2 of assembling optical components therein is performed. That is, in step 2, a process of supporting the backlight unit 330 on the cover bottom, disposing the guide panel 340 thereon, and attaching the display panel 360 to the upper guide panel is performed.

At this time, the guide rib 342 extending vertically from the horizontal support part on the guide panel 340 contacts one side of the connection holder 400 to prevent the vertical flow of the connection holder.

Next, in Step 3, the case top 410 is mounted. That is, the case top 410 is advanced from the front of the assembly in which the optical component is assembled, and the hook portion 428 of the connection holder 400 is formed in the hook hole 412 formed in the inner extension portion 414 of the case top 410. It is to engage the hook so that it hangs.

In this way, when the hook coupling in step 3 is made, the front end of the outer portion 416 of the case top 410 is smoothly contacted with the front end of the side portion 326 of the cover bottom 320, and as a result, the side portion of the cover bottom ( The outer surface of the outer surface 326 and the outer surface of the outer portion 416 of the case top 410 form the outer side surface of the display device or the entire set electronic device.

Next, in Step 4, the assembly is completed by fixing the connection holder 400 to the cover bottom 320 using the coupling screw 500.

As shown in FIG. 8, the reason why the case top 410 is hooked and then finally screwed in a state in which the connection holder 400 is temporarily assembled to the cover bottom 320 is connected in the process of hooking the connection holder 400. This is to prevent damage to the connection holder by ensuring the fluidity of the holder.

That is, if the case top is hook-coupled while the connection holder 400 is screwed to the cover bottom, the connection holder has a rigid structure such as that formed integrally with the cover bottom, so that the hook portion 428 in the hook connection process When a strong force is applied to the hook, there is a possibility that the hook portion may be damaged. In the case of assembling the process as shown in FIG. 8, the connection holder 400 is in a state that is only temporarily assembled with the cover bottom, so that it can flow to some extent Since there is an elastic part, the fluidity becomes larger, so that damage to the hook part as described above does not occur.

On the other hand, as one method of directly forming the outer side of the side of the set device or the display device without the front cover and back cover of the set device as shown in Figs. 1 and 2, it is connected as in the embodiment of the present invention. It is also possible to consider forming a hook structure directly on the side of the cover bottom without using the holder 400 and combining the hook structure with the corresponding hook structure of the case top.

However, in such a case, if a part of the hook of the cover bottom is damaged, it is cumbersome because the entire cover bottom needs to be replaced, whereas the use of the embodiment of the present invention has the advantage of being convenient because only the connection holder needs to be replaced.

In addition, if the connection holder 400 is used as in the embodiment of the present invention, after hooking the case top 410 to the cover bottom 320, and before finally fixing it with a coupling screw, the connection holder 400 is Flow is possible. Therefore, there is an advantage in that the possibility of damage to the hook portion or the like by strong pressure during the hook connection process is lower.

That is, when the hook structure is formed directly on the cover bottom, the hook structure is a rigid body formed integrally with the cover bottom, so there is a high possibility of damage by receiving a large force while the hook is pressed during the hook coupling process. According to this, in the hook connection process before the screw is fixed, the connection holder 400 not only has a certain degree of fluidity, but also has elasticity by the elastic portion 424, so there is little possibility of damage during the hook connection process.

According to the embodiment of the present invention as described above, by connecting the cover bottom and the case top supporting the backlight unit or the display panel in the display device so that the side surface directly forms the outer portion of the display device, separate front cover and middle There is an effect of removing the cover or back cover (or rear cover).

That is, by providing a connection holder that connects the cover bottom and the case top so that the cover bottom and the case top can be assembled while forming the outermost part of the display device without a separate cover, a simple and robust combination of the cover bottom and the case top is possible. Works

In addition, without the need for separate front and back covers, the cover bottom of the display device and the case top directly form the outer part of the display device without any problem in appearance, thereby simplifying the structure of the outer part of the display device and improving cost and assembly efficiency. Has the effect of being.
