[0036] Exemplary embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. However, the present invention may be embodied in different forms and should not be construed as limited to the exemplary embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0037] It should also be understood that when a layer is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Throughout the specification, like reference numerals refer to like components. In the drawings, the thicknesses of layers and regions are exaggerated for clarity.

[0038] Although terms such as "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms can be used to distinguish one element from another. Thus, without departing from the teachings of one or more embodiments, the first element discussed below can be referred to as the second element. Referring to an element as the "first" element may not require or imply the existence of a second element or other elements. The terms "first", "second", etc. may also be used herein to distinguish different classes or groups of elements. For the sake of brevity, the terms "first", "second", etc. can respectively represent "the first class (or the first group)", "the second class (or the second group)", etc.

[0039] The terms used herein are for the purpose of describing particular embodiments only and are not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms (including "at least one"), unless the context clearly dictates otherwise. "Or" means "and / or". As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. It should also be understood that when used in this specification, the terms "comprises" and / or "comprising" or "includes" and / or "including" specify the presence of the recited features, regions, wholes, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, components and / or their groups.

[0040] In addition, relative terms, such as "lower" or "bottom" and "upper" or "top", may be used herein to describe the relationship of one element to another as shown in the figures. It should be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. In an exemplary embodiment, when the device in one of the figures is flipped, an element described as on the "lower" side of other elements will then be oriented on the "upper" side of the other elements. Thus, depending on the specific orientation of the figure, the exemplary term "lower" can encompass both the "lower" and "upper" orientations. Similarly, when the device in one of the figures is flipped, an element described as "beneath" or "below" other elements will then be oriented "above" the other elements. Thus, the exemplary terms "beneath" or "below" can encompass both the above and below orientations.

[0041] As used herein, "about" or "approximately" includes the stated value and an average within an acceptable deviation range of the stated value as determined by one of ordinary skill in the art in view of the measurements discussed and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0042] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It should also be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and this invention, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0043] Exemplary embodiments are described herein with reference to cross-sectional views that are schematic illustrations of idealized embodiments. As such, variations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances are to be expected. Thus, the embodiments described herein should not be construed as limited to the specific region shapes shown herein, but should include deviations in shapes, for example, due to manufacturing. In an exemplary embodiment, regions shown or described as flat will typically have rough and / or non-linear features. Additionally, the sharp corners shown may be rounded. Thus, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the exact shape of the region and are not intended to limit the scope of the claims.

[0044] Upon concluding the detailed description, those skilled in the art will appreciate that many changes and modifications can be made to the preferred embodiments substantially without departing from the principles of the invention. Thus, the disclosed preferred embodiments of the invention are used only in a general and descriptive sense and not for purposes of limitation.

[0045] Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

[0046] Figure 1 is a perspective view of an exemplary embodiment of the peeling device. Figure 2 is along Figure 1 a cross-sectional view taken along line II-II' of Figure 3 is Figure 2 an enlarged view of region A of

[0047] Referring to Figures 1 to 3 , the peeling device 10 in the exemplary embodiment may include a water tank 100, a stage module 200, a peeling module 300, an outer wall 410, and a support member 420, wherein the peeling process is performed in the water tank 100, the stage module 200 adjusts the position of the target stack 20 (refer to Figure 5 ), and the peeling module 300 performs the peeling process on the target stack 20 (refer to Figure 5 ).

[0048] A space for performing the peeling process may be defined in the water tank 100. The water tank 100 is used to accommodate the stage 210, prevent the discharge blocking member 330, etc. To this end, an accommodation space for accommodating the above components may be defined in the water tank 100. The water tank 100 may include a bottom surface 110 and a side wall portion 120, and the side wall portion 120 is bent and extended upward at each edge along the perimeter of the bottom surface 110.

[0049] The height of the side wall portion 120 of the water tank 100 may be greater than the heights of the stage 210 and the discharge blocking member 330. In other words, the height of the upper end of the side wall portion 120 may be greater than the height of the upper end of the discharge blocking member 330, and may be greater than the height of the top surface of the stage 210 (i.e., one surface on which the target stack 20 (refer to Figure 5 ) may be provided (e.g., mounted)). That is, the entire area of the stage 210 and the entire area of the discharge blocking member 330 are provided in the water tank 100.

[0050] In addition, although not shown in the drawings, during the peeling process, the water tank 100 may be filled with a liquid filler WT (refer to Figure 5 ). In the exemplary embodiment, the liquid filler WT may be, for example, water (H2O), ethanol (C2H5OH), or a surfactant, but is not limited thereto.

[0051] The stage module 200 may include a stage 210, a height adjustment unit 220, and a centering unit 230, wherein the target stack 20 (refer to Figure 5 ) is provided (e.g., mounted) on the stage 210, and the height adjustment unit 220 adjusts the stage 210 and the target stack 20 (refer toFigure 5 ) height, the centering unit 230 aligns the target stack 20 (refer to Figure 5 ).

[0052] The table 210 can be disposed in the water tank 100 and spaced apart from the bottom surface 110 of the water tank 100 by a predetermined interval. That is, the table 210 can be disposed in the water tank 100 and above the bottom surface 110 of the water tank 100. The target stack 20 (refer to Figure 5 ) can be disposed (e.g., mounted) on the table 210. The height of the table 210 can be adjusted by the height adjusting unit 220.

[0053] Although the table 210 is shown as being horizontal with respect to the ground in the drawings, the present invention is not limited thereto. In an exemplary embodiment, the table 210 can be inclined at a certain angle with respect to the ground, and the angle can be in the range of 30 degrees to 60 degrees. In this case, the target stack 20 (refer to Figure 5 ) disposed (e.g., mounted) on the table 210 can also be inclined at a certain angle with respect to the ground, and the stripping device 10 can further include a separate fixing member for fixing the target stack 20 (refer to Figure 5 ) to the table 210.

[0054] The height adjusting unit 220 can include a height adjusting driver 221 and a table connector 222. Through the height adjusting unit 220, the height of the table 210 and the target stack 20 (see Figure 5 ) disposed (e.g., mounted) on the table 210 can be adjusted. That is, through the height adjusting unit 220, the table 210 and the target stack 20 (refer to Figure 5 ) can move up and down, and the target stack 20 (refer to Figure 5 ) can contact the stripping member 310 of the stripping module 300.

[0055] The height adjusting driver 221 can be vertically movably connected to the table connector 222 connected to the height adjusting driver 221 and the table 210 connected to the table connector 222. The height adjusting driver 221 can be disposed outside the water tank 100 and can be, but is not limited to, a linear motor or a cylinder.

[0056] The table connector 222 can connect the table 210 to the height adjusting driver 221. That is, the height of the table 210 can be adjusted by the vertical movement of the height adjusting driver 221.

[0057] The centering unit 230 can be disposed on one side of the table 210 to move the target stack 20 (see Figure 5)。One end of the centering unit 230 may be disposed on the table 210, and the other end of the centering unit 230 may be disposed on the table connector 222, but the present invention is not limited thereto.

[0058] The peeling module 300 may peel each stacked member (dummy DM, glass member GL, and film FL (refer to Figure 5 )) on the target stack 20 (refer to Figure 6 ). The peeling module 300 may include a peeling member 310, a peeling member support 320, a discharge prevention stopper 330, and a discharge prevention weight 340.

[0059] The peeling member 310 may be disposed above the table 210. In an exemplary embodiment, the peeling member 310 may be a roller. Although not shown in the drawings, when the target stack 20 (refer to Figure 5 ) is disposed (e.g., installed) on the table 210, the target stack 20 (refer to Figure 5 ) may be disposed between the table 210 and the peeling member 310. The surface of the peeling member 310 may be covered with rubber. The rubber covering the surface of the peeling member 310 may increase the frictional force between the peeling member 310 and the target stack 20 (see Figure 5 ). When the peeling member 310 rotates, the stacked member disposed at the uppermost part of the target stack 20 (refer to Figure 5 ) may be peeled off. A detailed description thereof will be given later.

[0060] The peeling member support 320 may support the peeling member 310. Specifically, when the peeling member support 320 is disposed above the water tank 100 and connected to the upper surface of the support 420 outside the water tank 100, the peeling member support 320 may be supported to be positioned above the water tank 100. In addition, the peeling member support 320 may be connected to the peeling member 310 to support the peeling member 310 such that the peeling member 310 is disposed above the table 210.

[0061] Although not shown in the drawings, the peeling member support 320 may further include a pressure adjustment spring, a pressure adjustment weight, and a peeling member driving unit. The pressure adjustment spring and the pressure adjustment weight may adjust the height of the peeling member support 320, and thus, may adjust the height of the peeling member 310 connected to the peeling member support 320. The driving unit of the peeling member 310 may drive the peeling member 310 to rotate the peeling member 310. The peeling member driving unit may be automatically driven or may be manually driven by an operator, but is not limited thereto.

[0062] When disposed on the target stack 20 (refer to Figure 5When the stacked member at the uppermost part of ()) is peeled off, the discharge prevention stopper 330 can be used to prevent the remaining stacked members other than the corresponding stacked member from being peeled off.

[0063] The discharge prevention stopper 330 can be disposed within the water tank 100 and outside the table 210. That is, the discharge prevention stopper 330 can be disposed between the table 210 and the side wall portion 120 of the water tank 100. In addition, the discharge prevention stopper 330 can be disposed below the peeling member 310. That is, the discharge prevention stopper 330 can overlap the peeling member 310 in the thickness direction (third direction DR3), but the present invention is not limited thereto.

[0064] The height of the uppermost end of the discharge prevention stopper 330 can be greater than the height of the lowermost end of the peeling member 310. That is, the discharge prevention stopper 330 is disposed below the peeling member 310 and spaced apart from the peeling member 310 by a predetermined distance, but the uppermost end of the discharge prevention stopper 330 can be disposed at a level higher by a first thickness W than the lowermost end of the peeling member 310 in the thickness direction (third direction DR3). Although not limited thereto, the first thickness W can be, for example, in the range of 0.5 millimeters (mm) to 1.0 mm.

[0065] In addition, the height of the discharge prevention stopper 330 can be greater than the height of the table 210. That is, the height of the uppermost end of the discharge prevention stopper 330 can be greater than the height of the upper surface of the table 210 (i.e., the surface on which the target stack 20 (refer to Figure 5 )) can be disposed (e.g., mounted)). The thickness of the discharge prevention stopper 330 in the third direction DR3 can be greater than the thickness of the table 210 in the third direction DR3, but the present invention is not limited thereto.

[0066] In addition, although not limited thereto, the height of the uppermost end of the discharge prevention stopper 330 and the height of the lowermost end of the peeling member 310 can be lower than the height of the uppermost end of the side wall portion 120 of the water tank 100. That is, all parts of the discharge prevention stopper 330 can be disposed within the water tank 100, and the lower part of the peeling member 310 can be disposed within the water tank 100.

[0067] The discharge prevention stopper 330 can include a base portion 331 and a tip portion 332 connected to the base portion 331. The base portion 331 is not limited thereto, but is connected to the bottom surface 110 of the water tank 100 and can have a uniform thickness (width in the first direction DR1). The thickness of the base portion 331 of the discharge prevention stopper 330 can be less than the length of the base portion 331 extending in the third direction DR3.

[0068] The tip portion 332 is connected to the base portion 331 and may have a thickness (width in the first direction DR1) smaller than the thickness (width in the first direction DR1) of the base portion 331. The thickness of the tip portion 332 may decrease toward its upper end. One surface of the tip portion 332 facing the table 210 may be referred to as the inner surface of the tip portion 332, and the other surface of the tip portion 332, which is the opposite surface of the inner surface, may be referred to as the outer surface of the tip portion 332. The inner surface of the tip portion 332 may have a rounded shape, but is not limited thereto.

[0069] One surface of the base portion 331 facing the table 210 may be referred to as the inner surface of the base portion 331, and the other surface of the base portion 331, which is the opposite surface of the inner surface, may be referred to as the outer surface of the base portion 331. In this case, the outer surface of the tip portion 332 and the outer surface of the base portion 331 may be aligned with each other.

[0070] The discharge prevention weight 340 may be provided above the table 210. Although not shown in the drawings, when the target stack 20 (see Figure 5 ) is set (e.g., installed) on the table 210, the discharge prevention weight 340 may apply pressure from top to bottom to the remaining stacked members except the stacked member (to be peeled) disposed at the uppermost layer of the target stack 20 (see Figure 5 ). Accordingly, the remaining stacked members can be prevented from moving along with the stacked member to be peeled, and the peeling of the remaining stacked members can be prevented.

[0071] As will be described later, since the peeling module 300 includes not only the peeling member 310 but also the discharge prevention stopper 330 and the discharge prevention weight 340, only one stacked member disposed at the uppermost portion of the target stack 20 (refer to Figure 5 ) including a plurality of stacked members can be automatically peeled, thereby improving the processing efficiency.

[0072] The outer wall 410 may be provided outside the water tank 100. The outer wall 410 may surround the water tank 100 at the outside of the water tank 100. The inside of the water tank 100 may be filled with the liquid filling WT, and the peeling process may be performed in a state where the water tank 100 is filled with the liquid filling WT. In this case, the liquid filling WT may flow out of the water tank 100. The outer wall 410 may collect the liquid filling WT flowing out of the water tank 100 in the outer wall 410.

[0073] The support member 420 may be provided below the outer wall 410 and the water tank 100. The support member 420 may be used to support components such as the outer wall 410 and the water tank 100, and a space where other components of the peeling device 10 may be provided may be defined on the support member 420.

[0074] Hereinafter, a method of peeling each stacked member from a target stack 20 including a plurality of stacked members (reference Figure 5 ) will be described. The glass members (multiple glass members GL), the films (multiple films FL), and the replicas (multiple replicas DM) (reference Figure 6 ) peeled from the target stack 20 (reference Figure 5 ) can be used as a protective member (or window) of a display device.

[0075] Figure 4 is a flowchart showing the sequential process of peeling each stacked member from the target stack. Figure 5 is a cross-sectional view showing the state in which the target stack is set (e.g., mounted) on the stage of the peeling device. Figure 6 is a side view of the target stack. Figure 7 is a cross-sectional view showing the glass member of the target stack.

[0076] Reference Figures 4 to 7 , a target stack 20 including a plurality of stacked members is prepared, and the target stack 20 is set (e.g., mounted) on the stage 210 (operation S01).

[0077] Although not shown, the target stack 20 can be transferred from the outside of the peeling device 10 to the stage 210 by a robotic arm or the like. In addition, the target stack 20 can be provided by cutting a part of the stacked multiple mother glass substrates into a desired shape. However, the method of forming the target stack 20 is not limited thereto.

[0078] The glass member GL can refer to a first glass member GL1 and a second glass member GL2. The film FL can refer to a first film FL1, a second film FL2, and a third film FL3. The replica DM can refer to a first replica DM1 and a second replica DM2.

[0079] The target stack 20 can include the glass member GL, the film FL, and the replica DM. That is, the target stack 20 can include the first glass member GL1, the second glass member GL2, the first film FL1, the second film FL2, the third film FL3, the first replica DM1, and the second replica DM2. Although two glass members GL and three films FL are shown in the drawings as being provided between the first replica DM1 and the second replica DM2, the number of glass members GL and the number of films FL are not limited thereto.

[0080] The target stack 20 may include a first replica DM1, a first film FL1, a first glass member GL1, a second film FL2, a second glass member GL2, a third film FL3, and a second replica DM2. The first replica DM1, the first film FL1, the first glass member GL1, the second film FL2, the second glass member GL2, the third film FL3, and the second replica DM2 may be stacked in this order. That is, the first replica DM1 is disposed at the uppermost part of the target stack 20, and the second replica DM2 is disposed at the lowermost part of the target stack 20. A plurality of glass members GL and a plurality of films FL may be disposed between the first replica DM1 and the second replica DM2. Each film FL may be disposed between the glass members GL, between the first replica DM1 and the first glass member GL1, and between the second replica DM2 and the second glass member GL2.

[0081] The first glass member GL1 and the second glass member GL2 may have substantially the same configuration. Hereinafter, for simplicity of description, the first glass member GL1 and the second glass member GL2 will be referred to as the glass member GL, but the description of the glass member GL may be applied to the first glass member GL1 and the second glass member GL2.

[0082] The glass member GL may have a plate-like sheet shape having a predetermined thickness. As will be described later, the glass member GL may be used as a window of the display device 30 (reference Figure 17 ). The glass member GL may be applied as a window (or a protective member) of the display device 30 (reference Figure 17 ), and may have a planar shape substantially similar to the planar shape of the display device 30 (reference Figure 17 ). In an exemplary embodiment, for example, when the display device 30 (reference Figure 17 ) has a rectangular shape, the planar shape of the glass member GL may also be rectangular.

[0083] In an exemplary embodiment, the glass member GL may include, for example, ultra-thin glass (“UTG”) or thin glass. Since the glass member GL includes an ultra-thin film or a thin film, the glass member GL may have a flexible property. That is, the glass member GL may be bent, folded, or rolled up. In an exemplary embodiment, the thickness of the glass member GL may be, for example, in the range of 10 micrometers (μm) to 300 μm. In an exemplary embodiment, for example, a glass member GL having a thickness in the range of 30 μm to 80 μm or a thickness of about 50 μm may be applied.

[0084] In an exemplary embodiment, for example, the glass member GL may include soda-lime glass, alkaline aluminosilicate glass, borosilicate glass, or lithium aluminosilicate glass.

[0085] The glass member GL may include chemically strengthened or thermally strengthened glass to have high rigidity. Chemical strengthening can be achieved by an ion exchange process in an alkaline salt. The ion exchange process may be performed two or more times.

[0086] The strengthened glass member GL may have a stress distribution in the depth direction from the surface. In an exemplary embodiment, for example, the glass member GL may include a compressive region CS at the surface and a tensile region CT within the compressive region CS. In the strengthened glass member GL, the stress is typically maximum at the surface and decreases toward its interior. At the boundary between the compressive region CS and the tensile region CT, a compressive depth DOL is defined as a point of stress equilibrium.

[0087] The glass member GL may be obtained by strengthening after cutting the glass in the mother substrate state into cell units. The glass strengthening process forms a compressive region CS near the surface. In an exemplary embodiment, for example, during the ion exchange process, the alkali metal salt and ions of the glass may be exchanged at the surface, and the exchanged ions may diffuse into the glass to form a compressive region CS having a compressive depth DOL. However, when the ion exchange process is performed in a state where the glass member GL is cut into cell units, the ion exchange may be performed through the side surface as well as the upper and lower surfaces of the glass member GL. Therefore, the compressive region CS may be provided not only near the upper and lower surfaces of the glass member GL but also near the side surface of the glass member GL.

[0088] Since the compressive region CS is provided near the surface of the glass member GL, the surface of the glass member GL may not be easily scratched. That is, the surface of the glass member GL may have excellent scratch resistance.

[0089] The first film FL1 to the third film FL3 may have substantially the same configuration. For simplicity of description, although the first film FL1 to the third film FL3 are referred to as the film FL, the description of the film FL may also be applied to the first film FL1 to the third film FL3.

[0090] The film FL may be a cured resin. During the process of stacking the plurality of mother substrates described above, the resin may be applied between the mother substrates to bond the mother substrates to each other. Therefore, when transferring the target stack 20, the target stack 20 can be transferred more stably.

[0091] The first replica DM1 and the second replica DM2 may have substantially the same structure as the glass member GL. However, the thicknesses of the first replica DM1 and the second replica DM2 may be greater than the thickness of the glass member GL. Since the first replica DM1 is disposed at the uppermost part of the target stack 20 and the second replica DM2 is disposed at the lowermost part of the target stack 20, the plurality of glass members GL disposed between the first replica DM1 and the second replica DM2 can be protected from external shocks that may occur during the transfer of the target stack 20.

[0092] The interior of the water tank 100 may be filled with a liquid filling WT. In an exemplary embodiment, for example, the liquid filling WT may be water (H2O). In the following description, it is assumed that the liquid filling WT is water (H2O), but the present invention is not limited thereto. In an exemplary embodiment, for example, the liquid filling WT may be ethanol (C2H5OH), a surfactant, or the like.

[0093] When the interior of the water tank 100 is filled with water (H2O), the table 210, the target stack 20 disposed (e.g., mounted) on the table 210, the lower portion of the peeling member 310, and the discharge prevention stopper 330 may be immersed in the water (H2O), and most of the peeling process may be performed in a state where the table 210, the target stack 20 disposed (e.g., mounted) on the table 210, the lower portion of the peeling member 310, and the discharge prevention stopper 330 are immersed in the water (H2O).

[0094] The temperature of the water (H2O) may be a temperature higher than zero degrees Celsius (°C), and the temperature range may be from 30°C to 90°C or from 70°C to 90°C, but is not limited thereto. When the temperature of the water (H2O) filling the interior of the water tank 100 is the temperature as described above, the peeling of the target stack 20 can be performed more easily.

[0095] Specifically, when the target stack 20 is immersed in the water (H2O) at the above temperature, it can weaken the bonding force of the first glass member GL1, the second glass member GL2, the first replica DM1, or the second replica DM2 in contact with the film FL. That is, when the film FL is immersed in the water (H2O) at the above temperature, the bonding force of the film FL itself can be reduced by physical and / or chemical changes. In addition, the water (H2O) can penetrate between the film FL and the first glass member GL1, the second glass member GL2, the first replica DM1, or the second replica DM2. Therefore, the film FL can be physically separated from the first glass member GL1, the second glass member GL2, the first replica DM1, or the second replica DM2. Accordingly, the frictional force between the film FL and the first glass member GL1, the second glass member GL2, the first replica DM1, or the second replica DM2 can be reduced, which makes it possible to perform the later peeling process more smoothly.

[0096] In addition, although not shown in the drawings, additional processes may be performed before the target stack 20 is set (e.g., installed) on the stage 210 such that the target stack 20 is immersed in water (H2O) at the above temperature in a separate space for 20 to 30 minutes.

[0097] Figure 8 is a cross-sectional view showing a state in which the target stack set (e.g., installed) on the stage is aligned. Figure 9 is Figure 8 an enlarged view of region B of

[0098] Then, referring to Figure 8 and Figure 9 align the target stack 20 set (e.g., installed) on the stage 210 (operation S02).

[0099] Specifically, by moving the centering unit 230 in the first direction DR1, the centering unit 230 can push the target stack 20 set (e.g., installed) on the stage 210 in the first direction DR1 to move the target stack 20 toward the discharge prevention stopper 330. In this case, the target stack 20 can be moved in the first direction DR1 until at least a part of the target stack 20 contacts the inner surface of the discharge prevention stopper 330. However, the method of moving the target stack 20 in the first direction DR1 is not limited thereto.

[0100] Thereafter, raise the stage 210 in the thickness direction (third direction DR3), and thus, the target stack 20 set (e.g., installed) on the stage 210 can be raised in the thickness direction (third direction DR3). By raising the target stack 20, the target stack 20 can contact the peeling member 310. The stage 210 and the target stack 20 set (e.g., installed) on the stage 210 can be raised by the height adjustment unit 220, but the method of raising the stage 210 and the target stack 20 set (e.g., installed) on the stage 210 is not limited thereto.

[0101] Figures 10A to 11B is an enlarged view of the periphery of the peeling member, showing how to peel the first replica of the target stack while Figure 10B is Figure 10A an enlarged view of a part of Figure 11B is Figure 11A an enlarged view of a part of Figure 12 is when the first replica of the target stack is peeled Figure 8 an enlarged view of region C at the periphery of the discharge prevention weight of

[0102] Referring to Figures 10A to 12, when the peeling member 310 rotates, the first replica DM1 stacked on the uppermost part of the target stack 20 is peeled off (operation S03).

[0103] By raising the table 210, the first replica DM1 provided at the uppermost part of the target stack 20 comes into contact with the peeling member 310. By rotating the peeling member 310, the first replica DM1 and some of the remaining stacked members other than the first replica DM1 can move in the first direction DR1. In this case, although the discharge prevention stopper 330 is provided on the movement path of the first replica DM1, the first replica DM1 can be peeled off from the target stack 20 and discharged to the outside of the water tank 100 over the tip portion 332 of the discharge prevention stopper 330 and the upper part of the water tank 100. The remaining stacked members provided below the first replica DM1 are blocked by the discharge prevention stopper 330 and cannot move in the first direction DR1, and the remaining stacked members are not peeled off.

[0104] Specifically, before the first replica DM1 is peeled off from the target stack 20, a hypothetical plane may extend from the lower surface of the first replica DM1 (i.e., the surface of the first replica DM1 facing the first film FL1). The hypothetical plane may be horizontal with respect to the ground. At the point where the hypothetical plane and the inner surface of the tip portion 332 of the discharge prevention stopper 330 intersect each other, the acute angle θ1 between the hypothetical plane and the inner surface of the tip portion 332 of the discharge prevention stopper 330 may be in the range of 1 degree to 30 degrees, or in the range of 10 degrees to 20 degrees, but is not limited thereto.

[0105] Corresponding to the table 210, the direction from the table 210 toward the discharge prevention stopper 330 is referred to as one side of the first direction DR1, and the direction from the table 210 toward the height adjustment unit 220 is referred to as the other side of the first direction DR1.

[0106] In a cross-sectional view, the peeling member 310 may rotate in a clockwise direction. Due to the frictional force between the peeling member 310 and the first replica DM1, the first replica DM1 can move in the first direction DR1 toward the discharge prevention stopper 330, that is, toward one side of the first direction DR1. In this case, when the acute angle θ1 between the hypothetical plane extending from the lower surface of the first replica DM1 and the inner surface of the tip portion 332 of the discharge prevention stopper 330 is the angle as described above, the first replica DM1 can continue to move upward along the inner surface of the tip portion 332 of the discharge prevention stopper 330 toward the discharge prevention stopper 330. When the peeling member 310 continues to rotate, the first replica DM1 can continuously move toward one side of the first direction DR1, thereby being peeled off from the target stack 20.

[0107] The remaining stacked members provided below the first copy DM1 of the target stack 20 can be slightly moved to one side in the first direction DR1 until they contact the inner surface of the tip portion 332 of the discharge prevention stopper 330 due to the shape of the tip portion 332 of the discharge prevention stopper 330. Although the remaining stacked members can be slightly moved to one side in the first direction DR1, when the stacked members meet the inner surface of the tip portion 332 of the discharge prevention stopper 330, the remaining stacked members can no longer move and are blocked by the discharge prevention stopper 330 to prevent movement to one side in the first direction DR1. That is, the remaining stacked members other than the first copy DM1 remain on the stage 210 without being peeled off from the target stack 20.

[0108] In addition, a discharge prevention weight 340 can be used to prevent the remaining stacked members other than the first copy DM1 from being peeled off. The discharge prevention weight 340 can be provided on the remaining stacked members other than the first copy DM1 while being provided on the other side of the target stack 20 in the first direction DR1. The discharge prevention weight 340 can have a predetermined weight and can be provided on the remaining stacked members other than the first copy DM1 so as to apply a load to the remaining stacked members. In this case, the load is applied downward in the thickness direction. By the load, the movement of the remaining stacked members to one side in the first direction DR1 can be suppressed or prevented. That is, when the discharge prevention stopper 330 blocks the movement of the remaining stacked members, the discharge prevention weight 340 also suppresses the movement of the remaining stacked members. Therefore, only the first copy DM1 provided at the uppermost part of the target stack 20 can be peeled off.

[0109] Figure 13 and Figure 14 are enlarged views of the periphery of the peeling member, showing how to peel the first film.

[0110] Reference Figure 13 and Figure 14 , after the first copy DM1 has been peeled off, by raising the stage 210 and the target stack 20 provided (e.g., mounted) on the stage 210 from which the first copy DM1 has been peeled off, the first film FL1 provided at the uppermost part of the target stack 20 from which the first copy DM1 has been peeled off is peeled off (operation S04).

[0111] By raising the stage 210 to raise the target stack 20 from which the first copy DM1 has been peeled off, the target stack 20 is moved so that the first film FL1 provided at the uppermost part of the target stack 20 contacts the peeling member 310.

[0112] After moving the first film FL1 to contact the peeling member 310, the peeling member 310 is driven to rotate the peeling member 310. By the rotation of the peeling member 310, the first film FL1 and some of the remaining stacked members other than the first film FL1 can move to one side in the first direction DR1. In this case, although the discharge prevention stopper 330 is provided on the movement path of the first film FL1, the first film FL1 can be peeled from the target stack 20 and discharged to the outside of the water tank 100 over the tip portion 332 of the discharge prevention stopper 330 and the upper part of the water tank 100. The remaining stacked members provided below the first film FL1 are blocked by the discharge prevention stopper 330 and the discharge prevention counterweight 340 from moving in the first direction DR1, and the remaining stacked members are not peeled.

[0113] The peeling operation S04 (only the first film FL1 is peeled from the target stack 20 from which the first replica DM1 has been peeled, and the remaining stacked members other than the first replica DM1 and the first film FL1 are not peeled) can be substantially the same as the peeling operation S03 of the first replica DM1 described in the reference Figures 10A to 12 However, in the cases of Figure 13 and Figure 14 , the difference is only that the first film FL1 is peeled instead of the first replica DM1, and the remaining stacked members other than the first replica DM1 and the first film FL1 are set on the table 210 without being peeled. Therefore, redundant descriptions will be omitted.

[0114] Figure 15 and Figure 16 are enlarged views of the periphery of the peeling member, showing how to peel the first glass member from the target stack from which the first replica and the first film have been peeled.

[0115] Referring to Figure 15 and Figure 16 , after peeling the first replica DM1 and the first film FL1, the first glass member GL1 provided at the uppermost part of the target stack 20 is peeled (operation S05) by raising the table 210 and the target stack 20 provided (for example, mounted) on the table 210 from which the first replica DM1 and the first film FL1 have been peeled.

[0116] By raising the table 210 to raise the target stack 20 from which the first replica DM1 and the first film FL1 have been peeled, the target stack 20 is moved so that the first glass member GL1 provided at the uppermost part of the target stack 20 contacts the peeling member 310.

[0117] After moving the first glass member GL1 to contact the peeling member 310, the peeling member 310 is driven to rotate the peeling member 310. By the rotation of the peeling member 310, the first glass member GL1 and some of the remaining stacked members other than the first replica DM1, the first film FL1, and the first glass member GL1 can move to one side in the first direction DR1. In this case, although the discharge prevention stopper 330 is provided on the movement path of the first glass member GL1, the first glass member GL1 can be peeled from the target stack 20 and discharged to the outside of the water tank 100 over the tip portion 332 of the discharge prevention stopper 330 and the upper portion of the water tank 100. The remaining stacked members provided below the first glass member GL1 are blocked by the discharge prevention stopper 330 and the discharge prevention weight 340 from moving in the first direction DR1, and the remaining stacked members are not peeled.

[0118] The peeling operation S05 (only the first glass member GL1 is peeled from the target stack 20 from which the first replica DM1 and the first film FL1 have been peeled, and the remaining stacked members other than the first replica DM1, the first film FL1, and the first glass member GL1 are not peeled) can be basically the same as the peeling operation S03 of the first replica DM1 described in the reference Figures 10A to 12 However, in the case of Figure 15 and Figure 16 the difference is only that the first glass member GL1 is peeled without peeling the first replica DM1, and the remaining stacked members other than the first replica DM1, the first film FL1, and the first glass member GL1 are provided on the table 210 without being peeled. Therefore, redundant descriptions will be omitted.

[0119] Subsequently, although not shown, by repeating the operation S04 of peeling the first film FL1 and the operation S05 of peeling the first glass member GL1, the second film FL2, the second glass member GL2, and the third film FL3 can be sequentially removed. Although only the first film FL1 to the third film FL3 and the first glass member GL1 to the second glass member GL2 are shown in the drawings, as described above, the number of the films FL and the number of the glass members GL are not limited thereto. Therefore, the number of repetitions of the operation S04 of peeling the first film FL1 and the number of repetitions of the operation S05 of peeling the first glass member GL1 can also vary according to the number of the films FL and the number of the glass members GL.

[0120] Subsequently, after all the films FL and all the glass members GL are peeled off, when the second replica DM2 provided at the lowermost part of the target stack 20 is removed (operation S06), the entire peeling process ends. The method of removing the second replica DM2 can be executed according to the operation S04 of peeling the first film FL1 or the operation S05 of peeling the first glass member GL1. However, without being limited thereto, the operator can directly remove the second replica DM2.

[0121] As described above, in the exemplary embodiment, when the stacking members of the target stack 20 are peeled off using the peeling device 10, each stacking member can be automatically peeled off from the target stack 20. In addition, a plurality of stacking members of the target stack 20 can be continuously peeled off without separate processing. Therefore, since the operator does not directly perform the peeling process, the safety of the operator can be ensured. In addition, the operation of peeling each stacking member can be repeatedly executed, thereby improving the efficiency of the peeling process.

[0122] Hereinafter, reference will be made to Figure 17 and Figure 18 to describe a display device including a glass member GL peeled off using the peeling device 10 in the exemplary embodiment.

[0123] Figure 17 is a plan view of an exemplary embodiment of a display device including a glass member peeled off using a peeling device. Figure 18 is when Figure 17 of the display device is folded. In Figure 18 , the protection member PRT exemplarily includes Figure 7 the first glass member GL1.

[0124] Reference Figure 17 and Figure 18 , the display device 30 displays a screen or an image through the display area DPA, and various devices including the display area DPA can be the display device 30. Examples of the display device 30 may include, but are not limited to, a smart phone, a mobile phone, a tablet personal computer ("PC"), a personal digital assistant ("PDA"), a portable multimedia player ("PMP"), a television, a game console, a watch-type electronic device, a head-mounted display, a monitor of a personal computer, a laptop computer, a car navigation system, a car dashboard, a digital camera, a video camera, an external billboard, an electronic billboard, various medical devices, various inspection devices, various household appliances such as a refrigerator and a washing machine including the display area DPA, an Internet of Things ("IoT") device, etc.

[0125] The display device 30 includes a display area DPA and a non-display area NDA. The display area DPA is an area for displaying a screen, and the non-display area NDA is an area for not displaying a screen.

[0126] In the display area DPA, multiple pixels PX can be set. The pixel PX is the basic unit for the display screen. The pixel PX can include, but is not limited to, red pixels, green pixels, and blue pixels. The multiple pixels PX can be alternately arranged in a plan view. In an exemplary embodiment, for example, the pixels PX can be arranged in a matrix, but the present invention is not limited thereto.

[0127] The non-display area NDA can be set around the display area DPA. The non-display area NDA can be set around the display area DPA and can surround the display area DPA. In an exemplary embodiment, the display area DPA can be set in a rectangular shape, and the non-display area NDA can be set around the four sides of the display area DPA, but the present invention is not limited thereto.

[0128] The display device 30 can include a folding area FDA, a first non-folding area NFA1, and a second non-folding area NFA2. The folding area FDA can be an area that is actually bent and folded across the center of the display device 30. The first non-folding area NFA1 and the second non-folding area NFA2 can be separated by the folding area FDA. A case where the widths of the first non-folding area NFA1 and the second non-folding area NFA2 are different from each other has been shown in the figure, but the first non-folding area NFA1 and the second non-folding area NFA2 can have the same width.

[0129] Each of the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2 can partially overlap with the display area DPA and the non-display area NDA.

[0130] The folding can be performed by an inward folding method of folding the display surface inward and / or an outward folding method of folding the display surface outward. Figure 18 An example of performing the folding in an outward folding manner is shown. When the display device 30 is folded, the display panel ATL and the protection member PRT are folded and bent together in the folding area FDA. The protection member PRT can be repeatedly folded and unfolded in the folding area FDA.

[0131] The display device 30 can include a display panel ATL and a protection member PRT provided on the display panel ATL.

[0132] Examples of the display panel ATL may include not only self-emissive display panels but also light-receiving display panels. Self-emissive display panels such as organic light-emitting diode ("OLED") display panels, inorganic electroluminescent ("EL") display panels, quantum dot ("QED") display panels, micro LED display panels, nano LED display panels, plasma display panels ("PDP"), field emission display ("FED") panels, and cathode ray tube ("CRT") display panels. Light-receiving display panels such as liquid crystal display ("LCD") panels and electrophoretic display ("EPD") panels.

[0133] The protection member PRT may include a film layer FIL and a first glass member GL1. The film layer FIL may perform an anti-scattering function. In an exemplary embodiment, for example, even when the first glass member GL1 is broken, since the fragments adhere to the film layer FIL, the scattering of the fragments can be prevented. Instead of or in addition to the anti-scattering function, the film layer FIL may perform other functions such as impact resistance.

[0134] The first glass member GL1 may be disposed on the film layer FIL. Since the first glass member GL1 has been described in detail above, redundant description thereof will be omitted.

[0135] A first bonding layer PSA1 may be disposed between the film layer FIL and the first glass member GL1. The first bonding layer PSA1 may be interposed between the first glass member GL1 and the film layer FIL to bond them. The first bonding layer PSA1 is preferably a tackifier layer, but may also be an adhesive layer.

[0136] A second bonding layer PSA2 may be disposed between the film layer FIL and the display panel ATL. The second bonding layer PSA2 may be a transparent layer such as an optically clear adhesive ("OCA") or an optically clear resin ("OCR"). The protection member PRT may be attached to the display panel ATL through the second bonding layer PSA2.

[0137] The protection member PRT may further include a printed layer PL disposed in the edge region. The printed layer PL is disposed in the non-display area NDA. The printed layer PL may be an edge coating. The printed layer PL may be a decorative layer that imparts aesthetic appeal and / or the outermost black matrix layer.

[0138] Hereinafter, other exemplary embodiments of the peeling device 10 will be described. In the following embodiments, the description of components that are the same as those in the above embodiments will be omitted or simplified, and the differences will be mainly described.

[0139] Figure 19A is a cross-sectional view showing another exemplary embodiment of the periphery of the peeling member of the peeling device, and Figure 19B isFigure 19A An enlarged view of a part.

[0140] Reference Figure 19A and Figure 19B , including the tip portion 332_1 of the discharge prevention stopper 330_1 in the peeling device 10_1 according to the illustrated exemplary embodiment and Figure 2 The exemplary embodiment is different in that the inner surface is not rounded.

[0141] Specifically, the peeling device 10_1 according to the illustrated exemplary embodiment may include a discharge prevention stopper 330_1, and the discharge prevention stopper 330_1 may include a base portion 331 and a tip portion 332_1. However, the inner surface of the tip portion 332_1 of the discharge prevention stopper 330_1 is not rounded, and the inner surface of the tip portion 332_1 is connected in a straight line from the upper portion to the lower portion of the tip portion 332_1. That is, the inner surface of the tip portion 332_1 of the discharge prevention stopper 330_1 may be inclined with respect to the first direction DR1 and the third direction DR3. In addition, at the point where the inner surface of the tip portion 332_1 and the imaginary plane extending from the lower surface of the first replica DM1 intersect, the acute angle θ2 between the inner surface and the imaginary plane may be in the range of 1 degree to 30 degrees, or in the range of 10 degrees to 20 degrees.

[0142] Similarly, in this case, when the peeling member 310 rotates, the stacked members of the target stack 20 can be automatically peeled off one by one, thus ensuring the safety of the operator and improving the efficiency of the peeling process.

[0143] Figure 20A is a cross-sectional view showing another exemplary embodiment of the periphery of the peeling member of the peeling device, and Figure 20B is Figure 20A An enlarged view of a part.

[0144] Reference Figure 20A and Figure 20B , including the discharge prevention stopper 330_2 in the peeling device 10_2 according to the illustrated exemplary embodiment and Figure 2 The exemplary embodiment is different in that it does not include a base portion 331 and a tip portion 332 and is provided in a cylindrical shape.

[0145] Specifically, the peeling device 10_2 according to the illustrated exemplary embodiment includes a discharge prevention stopper 330_2, and the discharge prevention stopper 330_2 does not include a base portion 331 and a tip portion 332 and may have a cylindrical shape or a roller shape extending in the second direction DR2. Therefore, the discharge prevention stopper 330_2 according to the illustrated exemplary embodiment is inFigure 20A The cross-sectional view can have a circular shape.

[0146] At a point where the surface of the discharge prevention member 330_2 and the imaginary plane extending from the lower surface of the first imitation member DM1 do not intersect with each other, the acute angle θ3 between the above-mentioned surface and the imaginary plane can be in the range from 1 degree to 30 degrees, or in the range from 10 degrees to 20 degrees.

[0147] Similarly, in this case, when the peeling member 310 rotates, the stacked members of the target stack 20 can be automatically peeled off one by one, thereby ensuring the safety of the operator and improving the efficiency of the peeling process.

[0148] Figure 21 It is a cross-sectional view showing another exemplary embodiment of the periphery of the peeling member of the peeling device.

[0149] Reference Figure 21 , including the peeling member 310_3 in the peeling device 10_3 according to the shown exemplary embodiment and Figure 2 The exemplary embodiment is different in that a friction member 311_3 is attached to at least a part of the surface of the peeling member 310_3.

[0150] Specifically, the peeling device 10_3 according to the shown exemplary embodiment includes a peeling member 310_3, and the surface of the peeling member 310_3 includes rubber, but the friction member 311_3 can be attached to at least a part of the surface of the peeling member 310_3. In this case, the friction member 311_3 can be attached to the surface of the peeling member 310_3 and can be in direct contact with each stacked member of the target stack 20. The friction member 311_3 can increase the frictional force between the peeling member 310_3 and the target stack 20. As the frictional force between the peeling member 310_3 and each stacked member of the target stack 20 increases, the peeling process by the rotation of the peeling member 310_3 can be performed more smoothly.

[0151] Similarly, in this case, when the peeling member 310_3 rotates, the stacked members of the target stack 20 can be automatically peeled off one by one, thereby ensuring the safety of the operator and improving the efficiency of the peeling process.

[0152] Figure 22 It is a cross-sectional view of another exemplary embodiment of the peeling device.

[0153] Reference Figure 22 , the peeling device 10_4 according to the shown exemplary embodiment is different from Figure 2 the exemplary embodiment in that it includes not only a peeling member 310 but also a sub-peeling member 310S.

[0154] Specifically, the peeling device 10_4 according to the illustrated exemplary embodiment includes a peeling module 300, but the peeling module 300 may include a plurality of peeling members 310. That is, the peeling device 10_4 according to the illustrated exemplary embodiment may include a peeling member 310 and a sub-peeling member 310S. The shape of the sub-peeling member 310S may be substantially the same as the shape of the peeling member 310.

[0155] The sub-peeling member 310S may be disposed above the table 210 and may be disposed between the peeling member 310 and the centering unit 230. In addition, the sub-peeling member 310S may have the same height as the peeling member 310. That is, the height from the top surface of the table 210 to the peeling member 310 may be the same as the height from the top surface of the table 210 to the sub-peeling member 310S. In this case, when the target stack 20 (refer to Figure 5 ) provided (e.g., mounted) on the table 210 is raised, the stacked members disposed at the uppermost part of the target stack 20 contact the peeling member 310 and the sub-peeling member 310S. When performing the process of peeling the stacked members disposed at the uppermost part of the target stack 20, by further including the sub-peeling member 310S, the peeling process can be performed more smoothly.

[0156] Similarly, in this case, when the peeling member 310 rotates, the stacked members of the target stack 20 can be automatically peeled one by one, thereby ensuring the safety of the operator and improving the efficiency of the peeling process. In addition, since the peeling device 10_4 includes not only the peeling member 310 but also the sub-peeling member 310S, even when the peeling member 310 is damaged, the peeling process can be performed only by the sub-peeling member 310S. Therefore, the peeling process can be performed continuously and smoothly.

[0157] Figure 23 is a cross-sectional view of another exemplary embodiment of the peeling device. Figure 24 is schematically showing how to pass through Figure 23 a cross-sectional view of the peeling device for peeling the stacked members from the target stack.

[0158] Refer to Figure 23 and Figure 24 , the peeling member 310_5 of the peeling device 10_5 according to the illustrated exemplary embodiment is different from the Figure 2 exemplary embodiment in that the peeling member 310_5 has a plate shape instead of a roller shape.

[0159] Specifically, the peeling member 310_5 of the peeling device 10_5 according to the illustrated exemplary embodiment is not provided in a roller shape, but may be provided in a plate shape. The peeling member 310_5 may be provided above the table 210 and may be connected to the peeling member support 320. The lower surface of the peeling member 310_5 (i.e., the surface facing the table 210) may include rubber. However, the peeling member 310_5 is not limited thereto, and for example, an adsorption member may be provided below the peeling member 310_5 to adsorb the target stack 20 (refer to Figure 5 ).

[0160] The peeling member 310_5 may move up and down (in the third direction DR3). After the target stack 20 is set (e.g., installed) on the table 210, the peeling member 310_5 provided on the table 210 may move downward to contact the target stack 20. Subsequently, when the peeling member 310_5 moves to one side in the first direction DR1, the stacking member provided at the uppermost part of the target stack 20 may move together with the peeling member 310_5 to be peeled off from the target stack 20.

[0161] Similarly, in this case, when the peeling member 310_5 moves, the stacking members of the target stack 20 may be automatically peeled off one by one, thereby ensuring the safety of the operator and improving the efficiency of the peeling process.

[0162] Although the exemplary embodiments of the present invention have been described with reference to the drawings, those skilled in the art will understand that various modifications can be made without departing from the scope of the present invention and without changing the basic features. Therefore, the above embodiments should be considered to be for descriptive purposes only and not for the purpose of limitation.
