As shown in FIG. 2B, the linear lamps 32 are spaced apart from each other at uniform intervals in the cover bottom 30 formed inside the reflector 31.

In this case, the lamps 32 may be separated and supported by a lamp guide (not shown) previously formed on the reflective plate 31 on the lower side of the cover bottom 30.                         

As shown in FIG. 2C, the supporter side 33 is positioned on side surfaces of the lamps 32, that is, on both open sides of the cover bottom 30, in a direction perpendicular to the direction in which the plurality of lamps 32 are formed. The plurality of lamps 32 are fixed.

As such, the structure including the cover bottom 30, the reflecting plate 31, and the plurality of lamps 32 is called a backlight unit 45.

As shown in FIG. 2D, a plurality of sheets 34a, 34b, 34c, and 34d are disposed on the cover bottom 30 including the plurality of lamps 32. Here, the sheets 34a to 34d emit light from the plurality of lamps 34 to uniformly diffuse light reflected from the reflector 31 inside the cover bottom 30 to correspond to the entire liquid crystal panel. Diffuser plate, protecting sheet, prism sheet having a prism function, and the like.

As described above, the structure including the cover bottom 30, the reflecting plate 31, the plurality of lamps 32, and the plurality of sheets 34a to 34d is referred to as a backlight unit 45.

3A and 3B are views showing the state in which the guide panel is assembled on the backlight unit from the top and back surfaces.

As shown in FIG. 3A, after assembling the backlight unit 45 and the plurality of sheets in the order of FIGS. 2A to 2D, a guide panel 46 is disposed at an edge of the upper portion of the backlight unit 45. Let's do it.

The guide panel 46 is a structure defining a position where a liquid crystal panel (not shown) corresponds to an upper portion of the backlight unit 45, and is mainly made of a material having a solid form of a plastic material.

As shown in FIG. 3B, when the backlight unit 45 including the guide panel 46 is turned upside down, the lower surface 30a has a step with the upper surface 30c at the rear surface of the cover bottom 30. The shape is observed. In addition, it can be seen that the guide panel 46 partially covers the backlight unit 45 and supports the backlight unit 45.

On the other hand, a liquid crystal panel (not shown) is mounted on the guide panel 46 to integrate the liquid crystal panel and the backlight unit 45.

4A and 4B illustrate a method of forming a driving unit of a liquid crystal display module.

As shown in FIG. 4A, a board assembly unit (not shown) that is formed in connection with a liquid crystal panel to generate a driving signal in the liquid crystal panel is folded to a lower rear surface of the liquid crystal panel and the backlight unit 45 so as to form a rear surface of the cover bottom 30. It is located in a predetermined portion of the upper side. That is, when the board assembly unit is folded from the liquid crystal panel to the backlight unit, the board assembly unit will correspond to the upper surface 30c and the lower surface 30a of the cover bottom 30.

In the figure, the board assembly unit is a state in which a gate drive IC and a gate PCB are mounted in the liquid crystal panel, and only one source PCB is connected to a predetermined portion of the upper side of the liquid crystal panel. The board assembly unit is formed on one side of the liquid crystal panel and folded downward so as to be in contact with the back surface of the upper surface 30c, the side surface 30b and the lower surface 30a of the cover bottom in order. 50) to protect and shield the board assembly unit from the outside. Here, the board assembly cover 50 is formed of a metallic material through a mold.

In addition, inverters 47a and 47b that apply voltage signals to the plurality of lamps 32 are positioned on the rear surface of the backlight unit 45, that is, on both sides of the lower surface 30a of the cover bottom 30. do. In this case, the inverters 47a and 47b are formed on the rear, left and right sides of the lower surface 30a among the surfaces forming the cover bottom 30. In this case, the inverters 47a and 47b are formed to be spaced apart from the upper and lower ends of the lower surface 30a of the cover bottom 30 by a predetermined interval.

As shown in FIG. 4B, the inverter covers 48a and 48b are formed on the surfaces of the inverters 47a and 47b in the same manner as the board assembly units by using metal molds to shield the inverters 47a and 47b from the outside. And protect. At this time, the inverter covers 48a and 48b are formed in a shape covering the inverters 47a and 47b on the lower surface 30a of the cover bottom 30. As the inverters 47a and 47b are spaced apart from the upper and lower ends of the lower surface 30a of the cover bottom 30 by a predetermined interval, the inverter covers covering the inverters 47a and 47b as well. 48a and 48b are also spaced apart from the upper and lower ends of the lower surface 30a of the cover bottom 30 by a predetermined interval.

5A is an enlarged view of a portion A of FIG. 4B, and FIG. 5B is a side photograph of the portion A of FIG. 4B.

5A and 5B, the inverter covers 48a and 48b are respectively provided through holes (not shown) provided in the lower surface 30a of the cover bottom 30 at predetermined portions 51 of the upper and lower portions, respectively. It is fastened through the screw 52. The predetermined portion 51 is formed so as to enter the height of the inverter cover (48a, 48b) to the side when manufacturing the inverter cover (48a, 48b) through a mold adjacent to the lower surface 30a of the cover bottom do.

Here, the inverter covers 48a and 48b, which are assembled to the lower surface 30a of the cover bottom, have a relatively thin thickness, and the fastening portions 51 of the inverter covers 48a and 48b and the cover bottom are liquid crystals. Since it is located at the outermost part of the display module and it is difficult to accurately engage with the hole when fastening through the screw 52, the bending or lifting may occur during the assembling or handling of the liquid crystal display module.

As such, when a gap between the lower surface 30a of the cover bottom and the inverter covers 48a and 48b occurs, a worker's hand may be torn or the work clothes may be caught, resulting in difficulty in handling.

In addition, when the inverter covers 48a and 48b are bent, the inverter covers 48a and 48b protect the inverters 47a and 47b and perform a function of safely blocking high current flowing through the inverters 47a and 47b. It is hard to see.
