BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging material for packaging a liquid crystal display module, and more particularly, to a method of removing a folding phenomenon by applying a tetragonal liquid crystal panel bag (PE-BAG).

In general, the driving principle of the liquid crystal display module uses the optical anisotropy and polarization of the liquid crystal. Since the liquid crystal is thin and long in structure, the liquid crystal has directivity in the arrangement of molecules, and the liquid crystal may be artificially applied to control the direction of the molecular arrangement.

Accordingly, if the molecular arrangement direction of the liquid crystal is arbitrarily adjusted, the molecular arrangement of the liquid crystal is changed, and light is refracted in the molecular arrangement direction of the liquid crystal due to optical anisotropy to express image information.

In addition, the liquid crystal display module includes a color filter substrate on which a common electrode is formed, an array substrate on which a pixel electrode is formed, and a liquid crystal filled between the two substrates. By driving the liquid crystal, it is excellent in characteristics such as transmittance and aperture ratio.

Hereinafter, the liquid crystal display module described above will be described with reference to the accompanying drawings.

1 is a perspective view illustrating a general liquid crystal display module.

As shown, the general liquid crystal display module 5 is largely composed of a liquid crystal panel 45 and a backlight unit 10.

Among these, the backlight unit 10 includes a cover bottom having a rectangular shape formed at the bottom thereof, and a reflecting plate including a plurality of fluorescent lamps 25 spaced apart in parallel at regular intervals on the cover bottom 15. (reflective plate, 20), a lamp holder (30) respectively configured at both ends to fix the fluorescent lamp 25, and the optical member 35 on the fluorescent lamp 25 The backlight unit 10 is configured.

The main supporter 40 surrounding the edge of the optical member 35 on the backlight unit 10, the liquid crystal panel 45 on the main supporter 40, and the liquid crystal panel 45. The upper and lower polarizers (not shown) attached to each of the upper and lower surfaces of the liquid crystal display module 5 include a top cover 50 covering the edges of the upper and lower polarizers.

The liquid crystal display module 5 thus manufactured is packaged in a liquid crystal panel packaging bag (hereinafter, abbreviated as PE-BAG) to prevent damage and damage to the product during transportation and transportation. It will be shipped through the space.

In addition, the main purpose of the packaging is a protective function for protecting the article and the merchandise and convenience. In particular, in transport packaging, packaging design should be such that the shape, dimensions and weight of the sheath are convenient for unloading.

Hereinafter, a method of packaging a general liquid crystal display module will be described with reference to the accompanying drawings.

2 is a view illustrating a method of packaging a liquid crystal display module using a general liquid crystal panel packaging bag (PE-BAG).

As shown, the step of aligning the buffer 70 on the pallet (60). At this time, the pallet 60 is used for the purpose of transportation.

In addition, the buffer 70 is used to prevent external impact or shaking that may occur during transport, and the buffer 70 is used as a styrofoam.

The buffer 70 has a plurality of grooves 65 formed in accordance with the design value of the short side of the liquid crystal display module 5 in both directions at regular intervals. Next, the worker proceeds to insert the liquid crystal display module 90 packed in the PE-BAG (80) in each of the grooves (65).

At this time, the general PE-BAG (80) is designed in a rectangular shape having a sufficient margin for charging the liquid crystal display module (5).

In the process of charging the liquid crystal display module 5 packaged in the rectangular PE-BAG 80 into each groove 65 of the buffer 70, the left and right sides of the short side (A) and the right side (B) are designed. Folding phenomenon occurs in the located PE-BAG (80). In particular, as a part of the extra PE-BAG (80) is folded, causing a friction with the buffer (70).

Here, the PE-BAG (80) made of SH92 (SH94: SKC fabric) material having a low hardness causes the PE-BAG (80) to be broken even with a small amount of friction. It is caused by the friction according to the hardness difference of the PE-BAG (80).

 Since the splitting wears out the buffer 70 or the PE-BAG 80, the PE-BAG 80 made of a material such as HH10 (hard coating: SKC fabric), which is expensive in the general liquid crystal display module 5, is used instead. There is a problem in that the manufacturing cost of using) increases.

In addition, even if such expensive PE-BAG is not used to solve the above-mentioned folding phenomenon, it has an element that can cause scratches on the liquid crystal panel.

The present invention has been made to solve the above-described problem, and an object thereof is to prevent a folding phenomenon, which occurs during the packaging of a liquid crystal display module, in particular.

To this end, in the present invention, a rectangular liquid crystal panel packaging bag (PE-BAG) is changed into a trapezoid shape, and a trapezoidal short side is inserted into each groove of the buffer while the liquid crystal display module is loaded in the PE-BAG. By doing so, the folding phenomenon can be eliminated.

In addition, inexpensive SH92 can be used instead of expensive HH10 material, thereby improving production yield.

The present invention for achieving the above object has a liquid crystal display module, a trapezoidal shape having a parallel short side corresponding to the short side of the liquid crystal display module, the parallel long side facing the liquid crystal display module, the long side is an open liquid crystal And a panel packaging bag.

The liquid crystal display module charging method according to the present invention for achieving the above object comprises the steps of preparing a liquid crystal display module, the step of charging the liquid crystal display module in a trapezoidal liquid crystal panel packaging bag of a pair of corresponding sides parallel; And inserting the liquid crystal panel packaging bag into which the liquid crystal display module is loaded so that a short side of the parallel sides is inserted into a buffer having a predetermined groove.

In this case, the liquid crystal panel packaging bag is characterized in that the material of the general charge-treated SH92 or SH94 (SKC fabric).

The liquid crystal display module may include a liquid crystal panel, upper and lower polarizers attached to each of an outer surface of the liquid crystal panel, and a backlight unit positioned on a rear surface of the lower polarizer.

Hereinafter, a method of charging a liquid crystal display module according to the present invention will be described with reference to the accompanying drawings.

First, the liquid crystal panel used for the liquid crystal display module described above will be briefly described.

3 is a cross-sectional view schematically illustrating a liquid crystal display module including a general liquid crystal panel, which will be described with reference to the drawings.

As illustrated, the color filter substrate, which is the upper substrate 100, and the array substrate, which is the lower substrate 130, face each other, and the liquid crystal layer 150 is spaced apart from the color filters and the array substrates 100 and 130. This intervenes.

Seal patterns 170 are formed at both outermost sides of the color filter and the array substrates 100 and 130 to seal the substrates 100 and 130.

An array element 155 is formed on the transparent substrate 102 of the array substrate 130 to correspond to the pixel area PA, and an upper front surface of the array element 155 protects it and for initial alignment of liquid crystals. The lower alignment layer 158 is formed.

The red, green, and blue sub color filters 120a, 120b, and 120c are sequentially formed on the transparent substrate 101 of the color filter substrate 100 to correspond to the pixel area PA of the lower substrate 130. In addition, a black matrix 125 for blocking the mixed and non-display sections of each of the color filters 120a, 120b, and 120c is configured at the boundary of each color.

In addition, a common electrode 175 of a transparent material is formed on each of the color filters 120a, 120b, and 120c and the black matrix 125, and the same function as that of the lower alignment layer 158 on the common electrode 175. An upper alignment film 157 is formed.

Here, the color filter and the array substrate 100 and 130 and the liquid crystal layer 150 are included and referred to as the liquid crystal panel 140. The liquid crystal panel 140 includes a liquid crystal 165 through a vertical electric field between the common electrode 175 of the color filter substrate 100 and the array element 155 of the array substrate 130, in particular, a pixel electrode (not shown). ) To adjust the amount of light transmitted.

Upper and lower polarizers 180 and 190 are attached to the outer surface of the liquid crystal panel 140 configured as described above. In general, the upper and lower polarizers 180 and 190 are made by adsorbing iodine or dichroic dye on a PVA film (polyvinyl chloride film) extending in one direction.

Hereinafter, a charging method of the liquid crystal display module according to the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, a trapezoid shape PE-BAG is manufactured, and the folding phenomenon can be eliminated by inserting one parallel side of the trapezoid into each groove of the buffer while the liquid crystal display module is loaded in the PE-BAG. Characterized in that it can.

This will be described below with reference to the accompanying drawings.

4A is a plan view showing a state in which a liquid crystal panel is loaded in PE-BAG, and FIG. 4B is a view showing a photograph of a state in which a liquid crystal panel in which PE-BAG is charged is buffered.

As shown in FIG. 4A, the liquid crystal display module 205 is mounted in the PE-BAG 280.

In this case, the PE-BAG 280 is characterized in that the pair of the corresponding side is a trapezoidal shape parallel to each other, the short side of the pair of the corresponding side to produce a size corresponding to one side of the liquid crystal display module 205. . At this time, the long side is an open form.

Therefore, after charging the liquid crystal display module 205 into the PE-BAG 280, if the short side of the PE-BAG 280 is inserted into the buffer (270 in Fig. 4b), the PE-BAG ( The folding phenomenon of 280 does not occur.

This will be described in detail with reference to FIG. 4B.

As shown in the drawing, when the liquid crystal display module 205 is charged to the PE-BAG 280, the short side of the PE-BAG 280 and the short side of the liquid crystal display module 205 are taut to each other. To interlock.

Due to this configuration, when inserting the PE-BAG 280 into the buffer 270, the friction between the two is reduced because it is inserted smoothly without the folded portion.

That is, when the short side of the PE-BAG 208 surrounding the liquid crystal display module 205 is inserted into each groove 265 of the buffer 270 while the short side is directed to the bottom, the groove is inserted into each groove 265. The folding phenomenon in the left side (C) and the right side (D) part of the short side will not occur.

In addition, since the structure of the PE-BAG 280 surrounding the liquid crystal display module 205 is maintained in a tight state, it is easy for an operator to load the liquid crystal display module 205, thereby improving production yield.

In this case, the buffer 270 is used to prevent an external impact or shaking that may occur during transport, and styrofoam is used as the buffer 270.

In addition, the buffer 270 into which the plurality of liquid crystal display modules 205 are inserted is loaded on the square plate-shaped pallet 260 and then moved to a desired place.

The manufacturing of the PE-BAG 280 in a trapezoidal shape is intended to facilitate the loading of the liquid crystal display module 205 into the open long side, but the important point is that the PE-BAG 280 is made of PE-BAG 280 without being spared in the portion inserted into the buffer 270. It is to design the BAG (280).

The PE-BAG 280 may be variously modified according to the design value of the liquid crystal display module 205.

When using the liquid crystal display packaging bag (PE-BAG) according to the present invention, since the folding phenomenon does not occur, the friction with the polarizing plate is minimized, so that the splitting phenomenon does not occur. As a result, an inexpensive SH92 (SH94 SKC) material can be applied in place of the expensive HH10 (hard coating SKC) PE-BAG.

According to the present invention, the rectangular liquid crystal panel packaging bag (PE-BAG) is changed into a trapezoidal shape, and the folding phenomenon is prevented from occurring by sandwiching the short side of the liquid crystal panel packaging bag in which the liquid crystal display module is loaded into the buffer.

Therefore, it is possible to apply a low-cost SH10 material to not only reduce the production cost, but also because the folding does not occur, it is easy to fit the buffer work has the effect of improving the production yield.
