Description

[0001] The present invention relates to a laminating method using a slit nozzle,

The present invention relates to a laminating method, and more particularly, to a method of laminating a liquid crystal display panel, which is capable of preventing a panel from being damaged by applying a complementary resin to a space generated by a polarizing plate and a combination resin, To a laminating method using a slit nozzle.

In recent years, touch screen panels, window glasses, and the like are laminated on a display panel. As shown in FIG. 1, the display panel 1 laminated in this way can attach the touch screen panel or the window glass 3 using the OCA film 2.

Meanwhile, in recent years, as shown in FIG. 2, in order to improve the productivity, a touch screen panel, a window glass 3 and the like are attached by using the OCR resin 5 in many cases. In this case, the precise amount of the OCR resin 5 is coated on the polarizing plate 4 attached on the display panel 1 by using a slit nozzle.

2, the polarizing plate 4 attached to the display panel 1 is smaller than the polarizing plate 4 attached to the display panel 1. In this case, 5, a slight empty space S is formed on the side surface between the display panel 1 and the window glass 3.

The empty space S formed in this manner creates an environment in which the display panel 1 or the window glass 3 can be easily damaged or broken. In fact, a large number of damages are generated in this portion, thereby causing defective products.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a polarizing plate and a slit nozzle capable of preventing a panel from being damaged by applying a supplementary resin to a space generated by a polarizing plate and a combination resin, To provide a laminating method.

According to another aspect of the present invention, there is provided a laminating method using a slit nozzle, comprising the steps of: 1) preparing a display panel having a polarizing plate attached on an inner side of a top surface thereof; 2) injecting the combining resin onto the polarizing plate using a slit nozzle; 3) attaching a bonding material on the combining resin; 4) applying a supplementary resin to the side of the bonding material with the display panel; 5) curing the combining resin and the supplementary resin.

In the present invention, it is preferable that the bonding material is a touch screen panel (TSP) or a cover glass.

Further, in the step 4) of the present invention, it is preferable that the supplemental resin is applied by a jetting method in a state where the display panel is mounted horizontally or standing vertically.

According to the present invention, since the joining resin is applied by using the slit nozzle to perform the cementing operation, it is possible to perform a very precise cementing operation, and also it is possible to apply the supplementary resin to the space generated by the polarizing plate and the joining resin, There is an advantage that it can be prevented.

1 and 2 are views showing a state where a window glass or the like is attached to a conventional display panel.
3 is a process diagram of a laminating method using a slit nozzle according to an embodiment of the present invention.
Figs. 4 and 5 are views showing embodiments of a method of applying a supplementary resin.
6 is a cross-sectional view showing the structure of a display panel manufactured according to the present invention.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the laminating method using the slit nozzle according to the present embodiment starts with a step S100 of preparing a display panel. In this step S100, the display panel 1 having the polarizing plate 4 attached on the inside of the upper surface thereof is prepared. At this time, the display panel 1 may have various structures such as an LCD and an AMOLED.

Next, a step S200 of applying the combining resin is performed. In this step S200, the summing resin is precisely applied only on the polarizing plate 4 in the upper part of the display panel 1. A slit nozzle is used to apply the matching resin by setting the area accurately.

Next, a step S300 of laminating the lapping material is performed. In this step S300, a laminating method is used in which laminating materials such as a touch screen panel (TSP) or a cover glass are gradually adhered from one side to the other side.

Next, the step S400 of applying the supplementary resin 5 to the side of the display panel 1 and the bonding material 3 proceeds. 2, the supplementary resin 6 is applied to the empty space generated in the side surface portion of the display panel 1 and the cementing material 3 in the state where the cementing material 3 is stuck, It is to remove space.

4, the supplementary resin injection means 10 is disposed on the side of the display panel 1 in a state where the display panel 1 is held horizontally, And the supplementary resin 6 can be applied while the supplementary resin injection means 10 is moved horizontally.

5, in a state in which the display panel 1 is held vertically upright, the supplementary resin injection means 10 is vertically erected, Apply the resin. In this case, the replenishing yarn injection means 10 does not move, and the application operation can be performed while the display panel 1 is moving.

In this embodiment, as a method of applying the supplementary resin 6 in this step (S400), a jetting method is preferable because the supplementary resin can be injected accurately and quickly.

Next, a step S500 of curing the combining resin and the supplementary resin proceeds. Of course, if necessary, the combining resin 5 may be cured first and the supplementing resin 6 may be cured later. It is also possible to finally cure the filler resin in a fully cured state before the filler resin is applied.
