Recently, demand for products such as display panel and touch panel has increased sharply due to the launch of various digital devices such as smart phones, tablet PCs, notebooks, navigation and digital TVs. In particular, mobile phones that have been specialized in existing communication functions have evolved into smart mobiles with performance close to that of notebook PCs, and have come to the era of smart mobile that enables them to enjoy high level of work and leisure by wireless. The low voltage driving, low power consumption, Various types of display devices in which components such as a high-density semiconductor package are mounted are used so as to realize features such as color rendering.

In such a display device, a digitizer for inputting an electrical graphic signal on a screen as well as an image is used, which is equipped with a touch screen panel.

Here, the touch screen panel is a peripheral device for inputting predetermined information to a computer by pressing the touch screen panel while the user views the screen on the display surface of the display device, and generates a voltage or current signal corresponding to the pressed position of the stylus pen or finger And inputs a command or graphic information designated by the user.

The importance of the performance of such a display device is further emphasized, and development of technology for outdoor visibility is continuously required. In other words, in the case of a display device, the digital device is always watched for the purpose of productivity improvement and leisure activity while being moved indoors as well as outdoors, and the user's eye health is deteriorated. A technical improvement is demanded from the problem that the visibility of the product is low.

Therefore, in order to improve brightness and brightness on a touch panel of a display device, another type of panel, which is a panel, is attached to one panel. In the case of a substrate attached to a panel, an optical clear adhesive (OCA) Lt; / RTI >

However, in the prior art in which the panel and the substrate are attached to each other via the optical tape, a step due to the adhering surface to the optical tape is generated, so that an air layer is generated in the display device, There was a problem.

In order to solve the problems of the prior art, recently, an optical clear resin (OCR) is applied as an ultraviolet ray curable solvent (UV solvent) instead of an optical tape and then cured, A technique of attaching a metal plate is used.

Here, the optical transparent adhesive (hereinafter referred to as OCR solution) has a high transparency, an excellent adhesive force and weather resistance, and a refractive index matching adhesive, which improves the visibility of the display in a bright external environment. Further, the optical transparent adhesive can fill the existing air gap with the optical transparent resin, thereby making it possible to reduce the thickness of the panel, thereby achieving high visibility and indexability.

In order to adhere the panel and the substrate using the OCR solution, the OCR solution is coated between the panel and the substrate, the panel and the substrate are pressed with a predetermined pressure, and the ultraviolet ray is irradiated to cure the OCR solution as the curing solvent The panel assembly equipment for the panel is used.

[0004] As a conventional technique disclosed in connection with the panel laminating equipment as described above, Korean Registered Patent No. 917800 (Sep. 10, 2009) discloses a chamber for providing a predetermined processing space, a chamber disposed at one side of the processing space, A stage for supporting a stereoscopic lens panel to be brought into the chamber, a stage disposed on one side of the processing space and facing the stage, for supporting a display panel to be carried into the chamber, and a platform lifting / And a coating module which is adapted to apply a sealing agent to at least one of the three-dimensional lens panel and the display panel which is reciprocated between the three-dimensional lens panel supported by the base and the display panel supported by the stage, And a curing portion disposed on the other side of the curing portion and curing the sealing agent, The stereoscopic lens panel and the display panel are transferred from one side of the processing space to the other side of the processing space to position the adhering panel to the hardening unit, There has been known a display panel cementing apparatus for a stereoscopic image capable of minimizing bubbles and foreign matter and applying the sealing agent so as to have a uniform thickness.

However, in the above-mentioned conventional technique, when the three-dimensional lens panel (substrate) is brought into contact with the display panel coated with the sealant, which is a curable solvent, And there is a problem that the quality of the product is deteriorated because the state of lamination between the different panels is uneven.

Further, conventionally, since a liquid curable solvent is applied on a panel and pressure is applied to another panel immediately, the liquid curable solvent leaks due to the pressure generated during the lining process, thereby contaminating the surrounding environment of the panel as well as the equipment, Furthermore, when the curable solvent is cured in the state of being leaked, the product is often defective, and the post-treatment process is required, thereby lowering the productivity.

In addition, conventionally, since the curing is performed at a time toward the panel which is in a mutually interwoven state, the hardenable area of the product is narrow and the curing efficiency is low, so that the durability of the product is low and the performance of the display device is deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a method of joining a substrate for a touch panel according to the present invention will now be described in detail with reference to the drawings.

7 and 8, the method for laminating a substrate for a touch panel according to the present invention includes a step S10 of loading a substrate F and a panel P, a step of applying an OCR solution A step S30 of aligning the panel P and a step S50 of bonding and finally curing the panel F to the substrate F, a step S30 of hardening the OCR solution, a step S40 of aligning the panel P, And unloading the panel P (S60).

In the step S10 of loading the substrate F and the panel P, the substrate F and the panel P are separately loaded from the outside.

In this case, the substrate F and the panel P are placed so as to be separated from each other and to be in a stacked state, both of them being flat and horizontal.

In the step of applying the OCR solution (S20), the OCR solution is uniformly sprayed on one surface (upper surface) of the panel P in a lump.

In step S30 of hardening the OCR solution, ultraviolet rays are irradiated toward the panel P coated with the OCR solution before bonding the panel P to the substrate F to harden the OCR solution.

It is preferable that ultraviolet rays irradiated to the panel P in order to harden the OCR solution are applied to irradiate ultraviolet rays generated by the LED light source.

After the OCR solution of the panel P is hardened, it is recognized whether or not the panel P is aligned, and the panel P is aligned so as to perform alignment correction.

In order to align the panel P, the panel P is recognized and corrected.

A predetermined pressure is applied to the substrate F so as to contact the one side of the substrate F on the panel P to join the panel P to the panel P, And the substrate F are cemented together and the OCR solution on the panel P is cured.

In order to bond the substrate F to the panel P coated with the OCR solution, the substrate F is adsorbed and fixed. Then, the OCR solution is positioned on the upper side of the panel P in the hardened state, P to the substrate F to bond the panel P and the substrate F together.

When bonding the substrate F to the panel P, the substrate F is bonded to the panel P in a state in which one end of the substrate F is tilted downward. That is, in the case of the substrate F to be pressed toward the panel P, the panel P is pressed so as to partially contact the substrate F, and the whole contact surfaces are sequentially pressed so that the substrate F is uniformly Respectively.

The tilting angle of the substrate F is tilted so that the substrate F has an inclination angle of 5 to 10 degrees with respect to the panel P, So that the tilting angle of the fingertip F can be maintained.

When the substrate F is tilted, the substrate F is gripped and fixed at one end (upper end) of the substrate F so as to maintain a flat state at an inclined tilting angle.

In order to hold and fix one side of the substrate F, the substrate F is fixed so as to keep the flat state until the substrate F is entirely joined to the panel P.

When the substrate F is bonded to the panel P, ultraviolet rays are irradiated so that the OCR solution can be finally cured in the bonding process of pressing the substrate F to the panel P, so that the OCR solution is completely cured.

In the step S60 of unloading the panel P, the substrate F transfers the cured panel P in a joined state and unloads the separated panel P to a separate subsequent process.

That is, according to the present invention, since the liquid OCR solution is applied to the panel, the substrate is adhered to the panel after lamination, and the OCR solution leaks during the attaching operation It is possible not only to keep the working environment clean, but also to improve the production rate of the good product of the product, to improve the curing efficiency of the OCR solution, to greatly improve the quality of the produced product, and to improve the productivity by eliminating the post treatment process.

In addition, since the present invention is configured to gradually cure the OCR solution applied to the panel through the sequential steps, it is possible to improve the quality of the product by improving the laminating efficiency of the product and improve the functionality and durability of the product.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. And this is also within the scope of the present invention.
