Description

TECHNICAL FIELD [0001] The present invention relates to a display component using a slim glass having a shatterproof film and a manufacturing method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display component and a method of manufacturing the same, and more particularly, to a display component employing a slim glass having a flexible, ultra-thin and shatterproof film laminated thereon and a method of manufacturing the same.

A display such as a liquid crystal display (LCD), an organic light emitting diode (OLED), and electrophoresis (EPD) forms a screen. Touch screens are widely used in mobile devices such as mobile phones, smart phones, tablets, and information processors such as ATMs and kiosks. In order to prevent the screen from being damaged by touching the touch screen or by collision or scratch, a display part using a slim glass is adopted. Such display components include, for example, mobile devices, information processing devices or desktop windows, protective sheets, and the like. In recent years, a thin, light, and flexible display device has appeared. In order to meet this trend, the thickness of slim glass applied to the device is becoming thinner. The flexible slim glass has a thickness of, for example, about 10 mu m to 300 mu m.

In the physical properties of the flexible slim glass, the thickness contributes a great deal. That is, as the thickness becomes thinner, the degree of bending increases, and the fracture mechanism of the slim glass changes. 1 is a cross-sectional view illustrating a breakage mechanism according to the thickness of a flexible slim glass. As shown, when the slim glass GL1 having the thickness T1 is broken, cracks CR and chipping CH occur simultaneously. On the other hand, when the slim glass GL2 of the thickness T2 is broken, only the crack CR is induced. The slip glasses GL1 and GL2 are attached to the scattering prevention film RF to prevent the fragments from being blown.

However, the slim glass GL1 in which a crack CR accompanies the fragment CH is not preferable as a display part. This is because the fragment CH is scattered to give a wound to the user, such as a stab wound, or can be sucked into the human body and cause illness. In addition, the edge knife (EK) formed while the fragment (CH) is generated can be exposed to the outside, and can cause serious stabbing to the user. In this case, the scattering-prevention film RF can not exhibit the function of preventing scattering of the fragment CH. Usually, the thickness T1 of the slim glass GL1 having the breakage mechanism accompanied by the fragment CH and the crack CR is known to be approximately 150 mu m to 300 mu m. Such a slim glass (GL1) is referred to as a slim flexible glass.

The slim glass GL2 in which a crack CR not accompanied by the fragment CH is generated is suitable as a display component. This is because the above-described accident does not occur because there is no scattered fragment CH. The thickness T2 of the slim glass GL2 is approximately 10 mu m to 150 mu m. Since the slice glass GL2 does not generate the fragment CH and the sharp edge EK, the damaged slim glass GL2 is stuck to the scattering prevention film RF and can secure stability. The slim glass (GL2) satisfying the above conditions is called a super slim flexible glass in order to distinguish it from the slim glass (GL1). However, since the slim glass GL2 has a small thickness T1, the edge ED becomes like a blade, which causes the user to scratch the back of the glass. Accordingly, it is important to safely treat the edge (ED) of the slim glass GL2.

A problem to be solved by the present invention is to provide a display component using a flexible glass having a breakage mechanism that is flexible and does not generate fragments and which prevents a beating caused by an edge, and a manufacturing method thereof.

In order to solve the problems of the present invention, a display component using a flexible slim glass is provided with a flexible slim glass having a thickness of 10 to 150 m and a flexible slim glass having a width W And a light blocking film comprising a transparent adhesive layer to which the slim glass is adhered and a transparent polymer film adhered to the transparent adhesive layer. At this time, the slim glass and the shrinkage preventing film are laminated so that the slim glass has a breakage mechanism in which cracks that do not accompany shards are generated, so that the generation of the shavings is suppressed, and the side- Lt; / RTI >

In the component of the present invention, the shatterproof film is cut by a laser, and the end portion of the shatterproof film projected portion includes a thermal deformed portion which is lost the adhesive force to the foreign matter by the heat of the laser. A maximum tangential line at which the slim glass and the anti-scattering film can be simultaneously contacted, and a maximum angle due to the maximum tangential line. In the display part, the slim glass side may have a contact angle such that it is positioned inside the maximum angle of the maximum tangential line. The side of the slim glass may be a rounded side. A maximum tangential line at which the rounded side surface and the anti-scattering film can be simultaneously contacted, and a maximum angle due to the maximum tangential line. And may have a contact angle such that the rounded side of the display component is located inside the maximum angle of the maximum tangential line. At this time, the contact angle is preferably 10 ° or more and 80 ° or less.

In order to solve the other problems of the present invention, one example of a manufacturing method of a display part using a flexible slim glass is to prepare a flexible slim glass having a thickness of 10 to 150 탆. Thereafter, a light-scattering film comprising a transparent adhesive layer laminated on one side of the slim glass and projecting outwardly of the slim glass by a width W, to which the slim glass is adhered, and a transparent polymer film adhered to the transparent adhesive layer, It does. At this time, the slim glass and the shrinkage preventing film are laminated so that the slim glass has a breakage mechanism in which cracks that do not accompany shards are generated, so that the generation of the shavings is suppressed, and the side- Lt; / RTI >

In one example of the method of the present invention, the end portion of the protruding portion of the anti-scattering film may form a heat deforming portion which is lost the adhesive force to the foreign substance by the heat of the laser. A method of laminating the light-scattering prevention film on one side of the slim glass comprises: laminating a light-scattering film cell protruding from the slim glass cell by a width (W) larger than the slim glass cell and being cut by a laser, Scattering prevention film that is larger than the width W of the film and is cut by a laser so as to have the width W or a large area flat anti-scattering film capable of accommodating a plurality of slim glass cells, Scattering prevention film is sandwiched between a plurality of slim glass cells and the scattering prevention film is cut with a laser so as to protrude by a width W with respect to each of the slim glass cells.

 Another example of a manufacturing method of a display part using a flexible slim glass for solving other problems of the present invention is a method of manufacturing a flexible flat large-sized glass having a thickness of 10 탆 to 150 탆 or a glass wound on a roll, Or to a shatterproof film wrapped on a roll. A mask defining the slim glass cell is then placed on the glass. The glass is removed in the shape of the mask to form a slim glass cell. The shrinkage preventing film is cut with a laser so as to protrude to the outside of the slim glass cell by a width W to form a slim glass cell having a shatterproof film laminated thereon.

In another example of the method of the present invention, the end portion of the protruding portion of the anti-scattering film may form a heat deforming portion which is lost the adhesive force to the foreign substance by the heat of the laser. In order to form the slim glass cell, the glass may be removed by dry or wet etching.

According to the display component using the flexible slim glass of the present invention and the method of manufacturing the same, the shatterproof film is cut by using a laser so as to protrude to the outside of the slim glass to have a breakable mechanism that does not generate debris, It is possible to prevent wounds such as stab wounds caused by the wrist. Also, it is suitable for force touch because of excellent touch feeling. Furthermore, by controlling the maximum tangential line and maximum angle between the anti-scattering film and the slim glass side, it is possible to reduce the damage caused by the staple to the maximum extent. In addition, by forming the heat deforming portion using the laser cutting, the adhesive force of the scattering prevention film is removed, and adhesion of foreign matters or dust or the like can be blocked.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to enable those skilled in the art to more fully understand the present invention. Also, in the figures, the thicknesses of the films (layers, patterns) and regions may be exaggerated for clarity. Further, when it is mentioned that the film (layer, pattern) is in the "upper", "upper", "lower", "one side" of another film (layer, pattern) Or a different film (layer, pattern) may be interposed therebetween.

An embodiment of the present invention is a display component which has a breakage mechanism that is flexible and does not generate fragmentation by cutting the scattering prevention film so as to protrude to the outside of the slim glass by using a laser, present. To this end, a detailed description will be given of the flexible slim glass and a process for preventing the slip by the edge will be described in detail. A display component according to an embodiment of the present invention is applied to a display device having a thin thickness, a light weight, and a flexible display device, for example, a window or a protective sheet of a mobile device or a desktop.

FIG. 2 is a cross-sectional view showing a part of a first display part 100 using a slim glass in which a light-scattering film according to an embodiment of the present invention is laminated.

2, the first display component 100 is composed of a slim glass 10 and a light-scattering film 20. The slim glass 10 has a breakage mechanism in which cracks that do not accompany debris occur. Since there are no scattered fragments and no sharp edges, there is no debris that injures or injures the user or is sucked into the human body. The thickness T3 of the slim glass 10 of the present invention is approximately 10 mu m to 150 mu m. Since the broken slim glass 10 is attached to the scattering prevention film 20, stability can be secured. The slim glass 10 satisfying the above conditions is also referred to as a super slim flexible glass. And has a total thickness T4 of the first display component 100. [ The thickness T4 can be appropriately selected in consideration of the degree of bending of the display device, the thickness T3 of the slim glass 10, and the like applied to the embodiment of the present invention.

The slim glass 10 is preferably a chemically reinforced optical glass, and may include a printing layer for expressing various functions. The print layer may be formed of any one or more of transparent, translucent, and / or color. The printing layer may be formed using inkjet printing or transfer using inkjet printing using silk printing or UV or thermal curing. On the slim glass 10, features such as fingerprint prevention, reflection prevention, blue light blocking, electromagnetic wave blocking, privacy, and antibacterial properties can be given. For example, a fluorine-based coating liquid may be wet-coated or may be dry-coated by vacuum deposition to form a fingerprint-preventing coating layer that provides a fingerprint-preventing function. .

In some cases, a printing layer may be formed on the light-scattering film 20 instead of forming the printing layer on the slim glass 10. In other words, the print layer may be formed on one or both of the slim glass 10 and the scattering-preventive film 20. The position of the print layer may vary depending on the shape, function, and the like of the display device to which the present invention is applied. In this case, the size of the screen of the touch screen panel can be adjusted more flexibly regardless of the print layer.

The shatterproof film 20 has a transparent adhesive layer 21 on one side of the transparent polymer film 22 and a transparent adhesive layer 23 on the other side. The transparent polymer film 22 may be formed of any one of PET (PolyEthylene Terephthalate), PEN (PolyEthyleneNaphthalate), PES (PolyetherSulfone), PI (Polyimide), PAR (Polyarylate), PC (PolyCarbonate), PMMA (PolyMethylMethAcrylate) Or any one or more of them. The transparent adhesive layer 21 may be composed of any one selected from the group consisting of an acrylic resin, a silicone resin or a urethane-based resin, a pressure-sensitive adhesive mixed with a crosslinking agent in a UV-curable resin or a mixture thereof or a copolymer thereof, An acrylic resin, a silicone resin, an epoxy resin, a urethane resin, or a composite resin thereof.

On the other hand, the anti-scattering film 20 may have a different structure depending on the curved surface display part to which it is applied. For example, if the display part is a window of a smart phone, the anti-scattering film 20 attached to the slim glass 10 may be free of the transparent adhesive layer 23. In some cases, for example, a transparent adhesive layer may be provided instead of the transparent adhesive layer 23, and a layer exhibiting other functions may be included. If the display part is a protective sheet of a smart phone, a transparent adhesive layer 23 may be required.

The anti-scattering film 20 is protruded to the outside of the slim glass side face 10a by a width W. The width W is approximately 10 mu m to 100 mu m, and the size of the width W can be variously adjusted within the scope of the present invention. The width (W) will be described in detail later with a focus on the maximum tangent line. Since the end portion of the scattering prevention film 20 is cut by the laser, there is a thermally deformable portion 24 deformed by the laser beam. Specifically, when the laser dissolves the end portion of the scattering-prevention film 20, the transparent adhesion layer 21, the transparent polymer film 22, and the transparent adhesive layer 23 are melted to lose the adhesive force. Since the hot deformable portion 24 has no adhesive force, it prevents foreign substances such as dust from adhering. The heat deforming portion 24 may be formed on a part or the whole of the end portion of the scattering prevention film 20 according to the display part according to the embodiment of the present invention.

The thermally deformable portion 24 contributes to reducing the thickness of the scattering prevention film 20. [ It may be possible to increase the thickness of the scattering prevention film 20 in order to prevent the slip glass side surface 10a from swelling. This increases the thickness of the transparent adhesive layer 21 of the scattering-prevention film 20 exposed to the outside of the slim glass 10, thereby forming a sticky layer near the slim glass side 10a. Foreign matter such as dust adheres to the sticky layer and the appearance is not clean, and the foreign matter causes a defect that occurs in the course of laminating. The anti-scattering film 20 according to the embodiment of the present invention has a thinner thickness than that described above, so that the thickness of the transparent adhesive layer 21 is also thin. When the thickness of the transparent adhesive layer 21 is thin, the side surfaces of the transparent adhesive layer 21 and the transparent adhesive layer 23 protruding out of the slim glass 10 are covered with the thermally deformable portion 24, .

In some cases, the first display component 100 of the present invention may further form a reinforcement band 30 that covers the side surfaces of the heat deformable portion 24 and the slim glass 10. The reinforcing band 30 is positioned on the upper surface of the shrinkage preventing film 20 protruding outside the slim glass 10 by the width W. At this time, the reinforcing band 30 is formed so as to surround the side surface of the slim glass 10. The reinforcing band 30 may be made of a polymer film or a cured material. In the case of the polymer film, a portion corresponding to the reinforcing band 30 may be formed by joining to the heat deforming portion 24. The reinforcing band 30 may be flush with the slim glass 10 or may cover a part of the slim glass 10. In the figure, the cured material is applied.

The curing material may be any one selected from a thermosetting resin and an ultraviolet curing resin, and more preferably an ultraviolet curing resin. For example, an ultraviolet curing resin is prepared by blending various types of acrylic units and a UV curing catalyst such as a polyurethane resin, an epoxy resin or a polyester resin. As a specific example of the ultraviolet curing material, urethane or acrylate oligomer, reactive monomer, photoinitiator and leveling agent are mixed as an ultraviolet reactive coating material. The urethane acrylate oligomer has a formula containing an aliphatic, cyclic aliphatic, aromatic compound or an oligomer of these compounds, and polyester polyol or polyether polyol is included in the molecular structure.

As the reactive monomer, trimethylpropane triacrylate, hexane diol diacrylate, pentaerythritol triacrylate and dipentaerythritol hexaacrylate are mixed and adjusted at a suitable ratio in consideration of hardness and adhesive force. As the photoinitiator, a usual polymerization initiator which is activated by ultraviolet rays is used, and in particular, hydroxycyclohexyl phenyl ketone, benzophenol, and phenyl-2-hydroxy-2-phenylketone are mainly used. The reinforcing band 30 formed by the curing material is formed by using a coating method by ejection, a coating method using a pad, a coating method by digital printing, or the like.

The reinforcing band 30 can prevent adhesion of foreign matter or dust or the like by removing the adhesive force of the scattering-preventing film 20 with respect to foreign matter. In addition, the step between the slim glass 10 and the scattering-prevention film 20 can be reduced to reduce the risk of stabbing the user. The reinforcing band (30) has high hardness and excellent elasticity, and there is no fear that harmful substances will be decomposed even for a long period of time. The reinforcement band 30 may have tackiness, but it is better not to be tacky. If there is no tackiness, the foreign matter of the outside does not adhere to the exposed portion of the reinforcing band 30, so that the aesthetic appearance of the first protective sheet 100 is not damaged. The reinforcing band 30 reduces steps of the transparent sheet 10 and the polymer substrate 20 and prevents the transparent sheet 10 from being broken to improve the stability of the first protective sheet 100. [

On the other hand, the slim glass 10 and the protruding scattering prevention film 20 can define the first maximum tangent line L (t1). The first maximum tangent line L (t1) has a first maximum angle? 1 with respect to the horizontal direction (x) of the first display component 100. Here, the first maximum angle [theta] 1 is the maximum angle that the first display component 100 can implement. The first maximum tangential line L (t1) and the first maximum angle? 1 are set in advance in consideration of the shape of the heat deforming portion 24 and the thickness T3 and width W of the slim glass 10 do. The first maximum tangent line L (t1) is a tangent line at which the slim glass side surface 10a and the heat deformable portion 24 can be simultaneously contacted. Therefore, when the first display part 100 is held by the first maximum tangent line L (t1), the slim glass side surface 10a and the heat deformable part 24 are simultaneously contacted.

Since the protruded width W is 10 占 퐉 to 100 占 퐉 and the thickness T3 of the slim glass 10 is 10 占 퐉 to 150 占 퐉, the first maximum angle? 1 is determined as follows. That is, tan? 1 = (T3 / W), and the minimum value of the first maximum angle? 1 is defined as tan? 1 = (10 占 퐉 / 100 占 퐉). Further, the maximum value of the first maximum angle? 1 is defined as tan? 1 = (150 占 퐉 / 10 占 퐉), and is therefore approximately 87 占. In other words, the first maximum angle [theta] 1 of the first display component 100 according to the embodiment of the present invention is within a range of approximately 6 [deg.] To 87 [deg.].

The first display component 100 according to the embodiment of the present invention preferably has a contact angle smaller than the first maximum angle? 1. When the contact angle is smaller than the first maximum angle? 1, the slim glass side surface 10a does not deviate from the first maximum tangent line L (t1). When the slim glass side face 10a is located inside the first maximum tangent line L (t1), the user grasps the end portion of the scattering prevention film 20 without coming into contact with the slim glass side face 10a, can do. The preferable contact angle is 10 占 to 80 占 which is smaller than the range of the first maximum angle? 1. This is because, in consideration of the deformation of the anti-scattering film 20, the contact angle is for securing the reliability of preventing the stabbing. Thus, the anti-scattering film 20 prevents the slim glass side 10a from hurting the user, such as a stab wound.

The first display part 100 according to the present invention is flexible and excellent in touch feeling by using the slim glass 10 and the shatterproof film 20 so as to be used in a force touch and a flexible display and has a shatterproof function, It is possible to prevent the side face 10a from wearing the staple and to prevent the side face 10a from being broken by the impact in the direction of the side face 10a and to minimize or prevent the generation of the debris due to the breakage of the slim glass 10. In this way, it is said to be minimized or suppressed.

3 is a cross-sectional view showing a part of a second display part 200 using a slim glass laminated with a light-scattering film according to another embodiment of the present invention. At this time, the second display component 200 is the same as the first display component 100 except that the slim glass 12 with rounded ends is applied. Accordingly, a detailed description of the overlapping portions will be omitted.

Referring to FIG. 3, the second display component 200 employs a slim glass 12 with a rounded side 12a. In the rounded side surface 12a, the rounded shape can be variously modified. Although the upper corner of the slim glass 12 is shown as being rounded in the drawing, it can be variously rounded within the scope of the present invention. Here, the upper corner is where the slant glass 12 and the anti-scattering film 20 are opposed to each other in the vertical direction y with respect to the lower side in contact with each other. The rounded side surfaces 12a may have a constant curvature and may be formed with different curvatures. As such, the rounded shape and position may be suitably adjusted within the scope of the present invention to avoid striking the user.

The second display component 200 can define the second maximum tangent line L (t2) of the slim glass 12 and the scattering-prevention film 20. The second maximum tangent line L (t2) has a second maximum angle 2 with respect to the horizontal direction x of the second display component 200. [ Here, the second maximum angle [theta] 2 is the maximum angle that the second display component 200 can implement. The second maximum tangent line L 2 and the second maximum angle 2 are set in advance in consideration of the shape of the heat deforming portion 24 and the thickness T 3 and width W of the slim glass 12 do. The rounded side surfaces 12a are formed such that the second maximum tangent line L 2 and the second maximum angle 2 are larger than the first maximum tangent line L 1 of the first display component 100 and the first maximum angle? θ1).

The first display component 100 according to the embodiment of the present invention preferably has a contact angle smaller than the second maximum angle [theta] 2. When the contact angle is smaller than the second maximum angle 2, the rounded side surface 12a does not deviate from the second maximum tangent line L (t2). When the rounded side face 12a is located inside the second maximum tangent line L2, the user grasps the end portion of the anti-scattering film 20 without coming into contact with the rounded side face 12a, can do. The preferable contact angle is 10 占 to 80 占 which is smaller than the range of the second maximum angle? 2, as in the case of the first maximum angle? 1. This is because, in consideration of the deformation of the anti-scattering film 20, the contact angle is for securing the reliability of preventing the stabbing. Accordingly, the anti-scattering film 20 prevents the rounded side surface 12a from being worn by the user, such as a stab wound.

4 is a cross-sectional view showing a part of a third display part 300 using a slim glass in which a light-scattering film according to another embodiment of the present invention is laminated. At this time, the third display part 300 is the same as the first and second display parts 100 and 200 except that the heat deforming part 24 is not formed. Accordingly, a detailed description of the overlapping portions will be omitted.

4, the scattering prevention film 20 of the third display component 300 is cut in such a manner that the heat deforming portion 24 is not formed. The cutting method does not use heat, such as etching or sand blasting. In this case, the heat-shrinkable portion 24 is not formed at the end portion of the shrink-preventive film 20. The third display part 300 of the present invention may further form a reinforcing band 30 covering the protruding part of the scattering prevention film 20 and the side surface of the slim glass 10. [ At this time, the reinforcing band 30 is the same as that described in Fig.

Hereinafter, a method of manufacturing the first to third display parts 100, 200, and 300 of the present invention will be described. For convenience of explanation, the display part attached to one display device is referred to as a display part cell, the slim glass constituting the display part cell is referred to as a slim glass cell, and the shatterproof film is referred to as a shatterproof film cell. Here, the slim glass and the anti-scattering film will be described with reference to Figs. 2 to 4. Fig.

There are many ways to manufacture display part cells. That is, a first method of joining a light-scattering film cell protruding from a slim glass cell by a width (W) larger than the slim glass cell, a light scattering film projecting from the slim glass cell to a width larger than a width W, There is a second method of forming a light-scattering film cell by cutting the film so as to have a width (W). Also, a plurality of slim glass cells are laminated on a large-area flat-shaped anti-scattering film or a roll-wrapped anti-scattering film capable of accommodating a plurality of slim glass cells, and the anti- As shown in Fig.

The above-described first to third methods have a problem in that the slim glass must be laminated in a cell shape, which may cause scars such as the above-mentioned stab wound. Further, the process of laminating the slim glass cell and the light-scattering prevention film (or the light-scattering film cell) is complicated and is not suitable for mass production. Hereinafter, a fourth method which is preferable for mass production without inducing a wound such as a stab wound is presented.

5 is a flowchart for explaining a method of manufacturing a display part according to an embodiment of the present invention.

Referring to FIG. 5, first, a large-area flat glass or a glass wound on a roll is laminated with a large-area flat anti-scattering film or a anti-scattering film wrapped with a roll (S10). Here, the large area is an area enough to accommodate the plurality of slim glass cells and the scattering-prevention film cell, and the flatness refers to a flat state, unlike the case where the film is wound on the roll. The method of laminating is not limited, and for example, a roller, a pad, or the like may be used. Thereafter, a mask defining the slim glass cell is placed on the laminated glass (S20). The glass in the non-masked portion is removed to form a slim glass cell (S30). When the glass is removed, the slim glass cell and the anti-scattering film remain. The method of removing the glass can be various, but an etching method using an etching solution or a sandblast is preferable.

Finally, the light-scattering film is cut with a laser so as to protrude to the outside of the slim glass cell by the width W, thereby forming a slim glass cell with the light-scattering film laminated (S40). At this time, the mask can be removed after etching or laser cutting. The fourth method proposed in the embodiment of the present invention does not involve the step of laminating the slim glass cell to the shatterproof film, so that a wound such as a staple generated during the laminating process does not occur. Further, since the slim glass cell and the scattering-prevention film cell are sequentially formed after laminating the large-area glass and the scattering-prevention film, the process is simple and mass production is easy. Furthermore, since the mask does not need to be transparent, the mask can be utilized as an alignment means for cutting the anti-scattering film cell.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications may be made without departing from the spirit and scope of the invention. It is possible.
