The outside of the back cover forming the display unit is formed as a non-conductive mold, and the inside is formed so that conductive molds blocking harmful waves are combined. It is intended to release harmful waves.

Description

Back Cover for Harmful Blocking of LCD Monitor

The present invention relates to an LCD monitor having a liquid crystal panel in which an image is displayed by a video signal of a computer. In particular, the present invention is more effective in preventing harmful emissions such as electromagnetic waves generated from the inside of the LCD monitor and improves productivity. The present invention relates to an improved LCD monitor.

In general, the LCD monitor, which is a kind of electronic products, emits harmful waves such as electromagnetic waves applied to EMI, and has an LCD monitor configuration for blocking such harmful waves.

In the conventional method for shielding harmful waves as described above, a shield is usually used, and FIGS. 1 and 2 show an LCD monitor employing a shield for shielding harmful waves.

That is, the LCD monitor is tilted by a display unit 1 having a liquid crystal panel 2 in which images are displayed in large divisions, and a hinge unit 3 having a hinge portion cover 3a. It is composed of a stand portion 4 is connected to enable the swivel operation.

In addition, the display unit 1 includes a front cover 5 and a back cover 6, and has a structure in which a circuit board 7 including a liquid crystal panel 2 is installed therebetween.

Accordingly, harmful waves are generated in the liquid crystal panel 2 and the circuit board 7, and the shield 8 is mounted inside the back cover 6 to block the harmful waves from being emitted toward the rear.

Therefore, in the related art, a separate shield 8 must be provided, and the cost of manufacturing the shield 8 including the press mold for manufacturing the shield 8 in a suitable form is a cost increase factor.

In addition, it is necessary to assemble a separate shield, which increases the total number of assembling process and causes a problem that causes a decrease in productivity.

In particular, the use of the shield is an obstacle to compact the LCD monitor because the thickness of the display is thickened because the space for mounting it is absolutely necessary.

The present invention has been made in view of the conventional problems as described above, it is possible to more effectively block harmful waves in the LCD monitor, and to reduce cost and improve the assembly.

The present invention for achieving the above object is to block harmful waves of a display unit having a liquid crystal panel on which an image is displayed, the outside of the back cover forming the display portion as a non-conductive mold material and the inside to block harmful waves The mold is characterized in that it is configured to be molded.

Hereinafter, the present invention will be described in more detail based on the attached preferred embodiments as follows.

Figure 3 shows an LCD monitor according to the present invention, a display unit having a liquid crystal panel (2) in which an image is displayed by a video signal input from the outside, and the hinge unit cover the display unit (1) It consists of the stand part 4 connected by the hinge part 3 which has 3a so that a tilt and a swivel operation are possible.

In addition, the display unit 1 includes a front cover 5 and a back cover 60 in which the present invention is implemented, and a structure in which a circuit board 7 including a liquid crystal panel 2 is installed therebetween. To achieve.

Accordingly, the back cover 60 according to the present invention is configured such that the outside is formed of the non-conductive mold material 61, and the conductive mold 62 is formed inside the non-conductive mold material 61.

That is, the non-conductive molding 61 and the conductive molding 62 are injection molded separately. Then, the conductive mold 62 is bonded to the non-conductive mold 61 or may be joined by another molding means to obtain an integrated back cover 60.

5 and 6 show a state in which the conductive molded article 61 and the non-conductive molded article 62 are coupled by a molding means.

Accordingly, in the case of FIG. 5, the non-conductive molding 61 and the conductive molding 62 are coupled by the screw 63. In the case of FIG. 6, the snap hook 64 is engaged with the locking jaw 65. ) So that they can be united with each other.

As such, when the conductive molded article 62 is provided inside the non-conductive mold article 61 that the back cover 60 itself is provided to the outside, harmful waves such as electromagnetic waves are transferred to the conductive molded article 62 as illustrated in FIG. 4. Absorption of the harmful waves to the outside of the back cover 60 is blocked by being absorbed and grounded.

Therefore, by adopting the back cover 60 as in the present invention, it is possible to block harmful waves without installing a separate shield inside as in the prior art, thereby reducing the parts and consequently reducing the assembly labor. .

According to the above description, it is a useful design to provide the effect that can be achieved by blocking the harmful wave and improve the productivity due to the improvement of the assembly and the cost reduction due to the reduction of parts.
