[0045] Hereinafter, the embodiments will be described in more detail with reference to the drawings that similar reference numerals always refer to similar elements. However, the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments shown herein. On the contrary, these embodiments are provided as examples so that the present disclosure will be thorough and complete, and the aspects and features of the present disclosure will be fully conveyed to those skilled in the art. Accordingly, processes, elements and techniques that are not necessary for a person of ordinary skill in the art to fully understand the aspects and features of the present disclosure may not be described. Unless otherwise noted, similar reference numerals represent similar elements throughout the drawings and written descriptions, and therefore their redundant descriptions may not be repeated.
[0046] When a certain embodiment can be implemented differently, the specific process order may be different from the described order. For example, two processes described successively may be performed simultaneously or substantially simultaneously, or may be performed in the reverse order of the described order.
[0047] In the accompanying drawings, for clarity, the relative size, thickness and ratio of elements, layers and regions may be exaggerated and / or simplified. Spatial relative terms, such as "beneath", "below", "lower", "under", "above", "upper" and the like may be used herein for convenience of explanation to describe the relationship between an element or feature and another element or feature (other elements or features) as shown in the figure. It will be understood that, in addition to the orientation depicted in the figure, spatial relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, the element described as "below" or "beneath" or "under" of other elements or features will be subsequently oriented "above" of other elements or features. Therefore, the exemplary terms "below" and "under" can cover both the orientations above and below. The device may be otherwise oriented (eg, rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0048] In the figure, the first direction DR1, the second direction DR2, and the third direction DR3 are not limited to the directions corresponding to the three axes of the rectangular coordinate system, and can be interpreted in a broader sense. For example, the first direction DR1, the second direction DR2, and the third direction DR3 may be perpendicular or substantially perpendicular to each other, or may represent different directions that are not perpendicular to each other.
[0049] It will be understood that, although the terms "first", "second", "third", etc., may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, the first element, first component, first region, first layer or first part discussed below can be referred to as the second element, second component, second region, second layer or second part without departing from the spirit and scope of the present disclosure.
[0050] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, the element or layer can be directly on, directly connected to, or coupled to the other element or layer, or there may be one or more intervening elements or layers. Similarly, when a layer, region, or element is referred to as being "electrically connected" to another layer, region, or element, it may be directly electrically connected to the other layer, region, or element, and / or may be indirectly electrically connected with one or more intervening layers, regions, or elements therebetween. Furthermore, it will be understood that when an element or layer is referred to as being "between" two elements or layers, the element or layer can be the only element or layer between the two elements or layers, or there may also be one or more intervening elements or layers.
[0051] The terms used herein are for the purpose of describing specific embodiments and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular forms "a" and "an" as used herein are also intended to include plural forms. It will also be understood that when the terms "comprise", "comprising", "include", "including", "has", "have" and "having" are used in this specification, the existence of the stated features, integers, steps, operations, elements and / or parts is described, but the existence or addition of one or more other features, integers, steps, operations, elements, parts and / or their clusters is not excluded. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. For example, the statement "A and / or B" means A, B, or A and B. Statements such as "at least one of...", when after a column of elements, modify the entire column of elements, and do not modify the individual elements in the column. For example, the expressions "at least one of a, b, or c," "at least one of a, b, and c," and "at least one selected from the cluster consisting of a, b, and c" indicate only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.
[0052] As used herein, the terms "substantially," "about," and similar terms are used as terms of approximation, and not as terms of degree, and are intended to take into account the inherent deviations of measurements or calculations that one of ordinary skill in the art would recognize. In addition, when describing embodiments of the present disclosure, the use of "may" refers to "one or more embodiments of the present disclosure." As used herein, the terms "use," "using," and "used" may be considered synonymous with the terms "utilize," "utilizing," and "utilized," respectively.
[0053] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present disclosure belongs. It will also be understood that, unless explicitly defined as such herein, terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and / or this specification, and should not be interpreted in an idealized or overly formal sense.

[0064] When the display device DD is folded, the first non-folding area NFA1 and the second non-folding area NFA2 may face each other, and the display device DD may be folded inwardly so that the display surface DS is not exposed to the outside. However, the present disclosure is not limited thereto. For example, the display device DD may be folded outwardly around the folding axis FX so that the display surface DS is exposed to the outside.

[0130] Figure 7 is along Figure 5 A cross-sectional view taken along line II' shown in FIG. Figure 8 It is shown Figure 7 A view of the bending state of the bending area shown in FIG.
[0131] exist Figure 7 , a cross section of the display module DM and a cross section of the window module WM corresponding to line II' are shown together.
[0132] Reference Figure 7 The display device DD may include a display module DM, a window module WM arranged on the display module DM, and a support portion SUP arranged below the display module DM. The display module DM may be a flexible display module. The display module DM may include a first non-folding area NFA1, a folding area FA, and a second non-folding area NFA2.
[0133] The window module WM may include a window WIN, a window protection layer WP, a hard coating layer HC, and a first adhesive layer AL1 and a second adhesive layer AL2.

The support part SUP may include a digitizer DGT, a support plate PLT, a cover layer COV, and a seventh adhesive layer AL7.
[0134] The configuration of the electronic panel EP and the panel protection layer PPL can be referred to above Figure 4 The configurations described are the same or substantially the same, and therefore, a redundant description thereof may not be repeated. The impact absorbing layer ISL may be disposed on the electronic panel EP. The impact absorbing layer ISL may protect the electronic panel EP by absorbing an external impact applied from the upper side of the display device DD toward the electronic panel EP. The impact absorbing layer ISL may be made in the form of a stretch film.
[0135] The impact absorbing layer ISL may include a flexible plastic material. The flexible plastic material may be defined as a synthetic resin film. For example, the impact absorbing layer ISL may include a flexible plastic material such as polyimide (PI) or polyethylene terephthalate (PET).
[0136] The window WIN may be arranged on the impact absorbing layer ISL. The window WIN may protect the electronic panel EP from external scratches. The window WIN may have an optically transparent property. The window WIN may include glass. However, the present disclosure is not limited thereto, and the window WIN may include a synthetic resin film.
[0137] The window WIN may have a multilayer structure or a single-layer structure. For example, the window WIN may include a plurality of synthetic resin films connected to each other (e.g., coupled or attached) with an adhesive, or may include a glass substrate and a synthetic resin film connected to each other (e.g., coupled or attached) with an adhesive.
[0138] The window protection layer WP may be disposed on the window WIN. The window protection layer WP may include a flexible plastic material such as polyimide or polyethylene terephthalate. The hard coating layer HC may be disposed on an upper surface of the window protection layer WP.
[0139] The printing layer PIT may be disposed on the lower surface of the window protection layer WP. The printing layer PIT may have a black color, but the color of the printing layer PIT is not limited thereto. The printing layer PIT may be adjacent to an edge of the window protection layer WP.
[0140] The barrier layer BRL may be arranged below the panel protection layer PPL. The barrier layer BRL may increase resistance to compression caused by external pressure. Therefore, the barrier layer BRL may be used to prevent or substantially prevent deformation of the electronic panel EP. The barrier layer BRL may include a flexible plastic material such as polyimide or polyethylene terephthalate.
[0141] The barrier layer BRL may have a color that absorbs light. For example, the barrier layer BRL may have a black color. In this case, when the display module DM is observed from above, components arranged under the barrier layer BRL may not be visually recognized.
[0142] The first adhesive layer AL1 may be disposed between the window protection layer WP and the window WIN. The window protection layer WP and the window WIN may be bonded to each other through the first adhesive layer AL1. The first adhesive layer AL1 may cover the printed layer PIT.
[0143] The second adhesive layer AL2 may be disposed between the window WIN and the impact absorbing layer ISL. The window WIN and the impact absorbing layer ISL may be bonded to each other through the second adhesive layer AL2.
[0144] The third adhesive layer AL3 may be disposed between the impact absorbing layer ISL and the electronic panel EP. The impact absorbing layer ISL and the electronic panel EP may be bonded to each other through the third adhesive layer AL3.
[0145] The fourth adhesive layer AL4 may be disposed between the electronic panel EP and the panel protection layer PPL. The electronic panel EP and the panel protection layer PPL may be bonded to each other through the fourth adhesive layer AL4.
[0146] The fifth adhesive layer AL5 may be disposed between the panel protection layer PPL and the barrier layer BRL. The panel protection layer PPL and the barrier layer BRL may be bonded to each other through the fifth adhesive layer AL5.
[0147] The sixth adhesive layer AL6 may be disposed between the barrier layer BRL and the digitizer DGT. The barrier layer BRL and the digitizer DGT may be bonded to each other through the sixth adhesive layer AL6.
[0148] The sixth adhesive layer AL6 may overlap the first non-folding area NFA1 and the second non-folding area NFA2, and may not overlap the folding area FA. In other words, the sixth adhesive layer AL6 may not be disposed in the folding area FA.
[0149] The digitizer DGT may be disposed below the barrier layer BRL. As an example, the thickness of the digitizer DGT may be in the range of 37.5 μm to 400 μm. The digitizer DGT may include multiple layers, which will be described in more detail below.
[0150] The digitizer DGT may be used to support the display module DM from the lower side of the display module DM. For example, the digitizer DGT may include a non-metallic material such as a reinforced fiber composite to have a higher rigidity than that of the display module DM. The reinforced fiber composite may be a carbon fiber reinforced plastic (CFRP) or a glass fiber reinforced plastic (GFRP). Hereinafter, as a representative example, the digitizer DGT may be described in more detail as having a structure including GFRP.
[0151] The digitizer DGT is a device for receiving position information indicated by a user on a display screen. The digitizer DGT can be implemented by an electromagnetic method (e.g., an electromagnetic resonance method). For example, the digitizer DGT may include a digitizer sensor substrate including a plurality of coils. However, the present disclosure is not limited thereto, and the digitizer DGT may be implemented by an active electrostatic method.
[0152] When the user moves the electromagnetic pen on the display device DD, the electromagnetic pen may be driven by an alternating current (AC) signal to generate an oscillating magnetic field, and the oscillating magnetic field may induce a signal in the coil. The position of the electromagnetic pen may be detected by the signal induced in the coil. The digitizer DGT may determine the position of the electromagnetic pen by sensing the electromagnetic changes that occur when the electromagnetic pen approaches.
[0153] A plurality of openings OP may be defined in a portion of the digitizer DGT overlapping the folding area FA. The openings OP may be formed to pass through the portion of the digitizer DGT in the third direction DR3. The openings OP may be formed in the digitizer DGT by a laser process or a micro-sandblasting process.
[0154] As the opening OP is defined in the portion of the digitizer DGT overlapping the folding area FA, the flexibility of the portion of the digitizer DGT overlapping the folding area FA can be increased. As a result, the digitizer DGT can be easily folded around the folding area FA.
[0155] The cover layer COV may be arranged under the digitizer DGT. The cover layer COV may cover the opening OP defined in the digitizer DGT under the digitizer DGT. The cover layer COV may overlap with the folding area FA and may not overlap with the first non-folding area NFA1 and the second non-folding area NFA2. In other words, the cover layer COV may not be arranged in the first non-folding area NFA1 and the second non-folding area NFA2. The cover layer COV may be in contact with the lower surface of the portion of the digitizer DGT where the opening OP is formed.
[0156] The cover layer COV may have an elastic modulus lower than that of the digitizer DGT. For example, the cover layer COV may include thermoplastic polyurethane or rubber, but the material of the cover layer COV is not limited thereto. The cover layer COV may be manufactured in the form of a sheet and attached to the digitizer DGT.
[0157] The support plate PLT may be arranged under the digitizer DGT. The support plate PLT may overlap the first non-folding area NFA1 and the second non-folding area NFA2, and may not overlap the folding area FA. The support plate PLT may be divided into two parts that may be arranged under the first non-folding area NFA1 and the second non-folding area NFA2, respectively.
[0158] The support plate PLT may have a higher rigidity than that of the display module DM. The support plate PLT may include a metal material such as stainless steel (e.g., SUS 316), but the metal material of the support plate PLT is not limited thereto. In addition, the present disclosure is not limited thereto, and the support plate PLT may include a non-metal material such as plastic.
[0159] The seventh adhesive layer AL7 may be disposed between the digitizer DGT and the support plate PLT. The digitizer DGT and the support plate PLT may be bonded to each other through the seventh adhesive layer AL7. The seventh adhesive layer AL7 may not be disposed in the folding area FA.
[0160] The first to seventh adhesive layers AL1 to AL7 may include a transparent adhesive such as a pressure sensitive adhesive (PSA) or an optically clear adhesive (OCA), but the type of the adhesive is not limited thereto.
[0161] The first hole H1 may be defined in a portion of the display module DM that overlaps with the first hole area HA1. The first hole H1 may be defined from the support plate PLT to the panel protection layer PPL. For example, the first hole H1 may be integrally defined in (e.g., may integrally penetrate) the barrier layer BRL, the digitizer DGT, the support plate PLT, and the fifth to seventh adhesive layers AL5 to AL7.
[0162] The second hole like the first hole H1 may be formed in the second hole area HA2 (see, for example, Figure 5), and the second hole can be defined from the support plate PLT to the panel protection layer PPL. The camera CA (for example, referring to Figure 3 ) may be arranged in the first hole H1, and the sensor SN (eg, referring to Figure 3 ) may be arranged in the second hole.
[0163] Reference Figure 7 and Figure 8 , the panel protection layer PPL and the fourth adhesive layer AL4 may not be arranged under the bending area BA. The panel protection layer PPL and the fourth adhesive layer AL4 may be arranged under the second area AA2 of the electronic panel EP. The data driver DDV may be disposed on the second area AA2 of the electronic panel EP.
[0164] The printed circuit board PCB may be connected to the second area AA2 of the electronic panel EP. The printed circuit board PCB may be connected to one side of the second area AA2. The bending area BA may be bent, and thus, the second area AA2 may be arranged under the first area AA1. Therefore, the data driver DDV and the printed circuit board PCB may be arranged under the first area AA1.
[0165] Fig. 9 yes Figure 7 A perspective view of the digitizer shown in .
[0166] Reference Figure 7 and Fig. 9 The digitizer DGT may include a first non-folding portion NFP1, a folding portion FP, and a second non-folding portion NFP2 arranged along the second direction DR2. The first non-folding portion NFP1, the folding portion FP, and the second non-folding portion NFP2 may overlap with the first non-folding area NFA1, the folding area FA, and the second non-folding area NFA2, respectively.
[0167] A grid pattern may be defined in the folding portion FP. For example, a plurality of openings OP may be defined in the folding portion FP. The openings OP may be arranged in a desired rule (e.g., a predetermined rule). The openings OP may be arranged in a grid shape to form a grid pattern of the folding portion FP. The area formed by the openings OP relative to the second direction DR2 may be smaller than the width of the folding portion FP.
[0168] As the opening OP is defined in the folding portion FP, the area of the folding portion FP may be reduced, and thus the rigidity of the folding portion FP may be reduced. Therefore, when the opening OP is defined in the folding portion FP, the flexibility of the folding portion FP may be increased compared to a case where the opening OP is not defined in the folding portion FP. As a result, the folding portion FP may be more easily folded.
[0169] The first hole H1 and the second hole H2 may be defined in the second non-folding part NFP2. The first hole H1 and the second hole H2 may be adjacent to an edge of the second non-folding part NFP2.
[0170] The digitizer DGT may include multiple layers. FIG. 10A to FIG. 13 The layers of the digitizer DGT are described in more detail.

Fig. 9 The described first non-folding portion NFP1 , the folding portion FP, and the second non-folding portion NFP2 are the same or substantially the same, and thus, redundant descriptions thereof may not be repeated or may be simplified.
[0176] Reference Fig. 10A , Fig.12 and Fig.13 , digitizer DGT (see, for example, Fig. 9 ) may include an active area AA and a non-active area NAA around (e.g., adjacent to) the active area AA. The non-active area NAA may surround the active area AA (e.g., around the periphery of the active area AA). The active area AA may be adjacent to the display area DA (e.g., see FIG. 1 ). Figure 1 ) overlaps, and the non-active area NAA may overlap with the non-display area NDA.
[0177] Digitizer DGT (see, for example, Fig. 9) may include a first layer LY1, a second layer LY2, and a third layer LY3. The first layer LY1, the second layer LY2, and the third layer LY3 may be sequentially laminated from top to bottom. In other words, the first layer LY1 may be arranged on the uppermost side, the second layer LY2 may be arranged below the first layer LY1, and the third layer LY3 may be arranged below the second layer LY2.

The main connector MCP may be arranged on one side of the digitizer DGT. As an example, the main connector MCP may be arranged in the non-active area NAA on the right side. The main connector MCP may be arranged in the second non-folding portion NFP2.
[0179] The first connector connection wiring CCL1 may be arranged in the non-active area NAA on the right side. The first connector connection wiring CCL1 may extend in the second direction DR2, may be arranged along the first direction DR1, and may be connected to the main connector MCP. The first sensing coil RF may be connected to the main connector MCP through the first connector connection wiring CCL1.
[0180] The first sensing coil RF may extend from the main connector MCP together with the first connector connection wiring CCL1 to form a loop shape. In this document, the loop shape may be simply referred to as a loop. For example, the first sensing coil RF extending from the main connector MCP (for example, extending from the first connector connection wiring CCL1 connected to the main connector MCP) may extend to the non-active area NAA on the right side, the active area AA, and the non-active area NAA on the left side, and may then extend to the active area AA and the non-active area NAA on the right side, and may be connected to the first connector connection wiring CCL1.

The first sensing coil RF connected to one of the first connector connection wirings CCL1 extending from the main connector MCP may extend multiple times to the non-active area NAA on the right side, the active area AA, and the non-active area NAA on the left side. The first sensing coil RF may extend multiple times to the non-active area NAA on the left side, and then may extend again to the active area AA and the non-active area NAA on the right side.
[0182] like Fig. 10AAs shown in , the first sensing coil RF connected to one first connector connection wiring CCL1 may form two loops. The first sensing coil RF may form two loops, and then may be connected to the first connector connection wiring CCL1 again, and may be connected to the main connector MCP. However, the present disclosure is not limited thereto, and one first sensing coil RF may form one loop.
[0183] Some of the first sensing coils RF are shown as loop shapes, the loop shapes of other first sensing coils RF are omitted, and other first sensing coils RF extend in the second direction DR2 inside the active area AA. However, the present disclosure is not limited thereto, and other first sensing coils RF may also extend into a loop shape.
[0184] Each of the plurality of first sensing coils RF may include a plurality of first extension wirings EL1 and a plurality of first connection wirings CL1. The first extension wirings EL1 may be arranged in the active area AA, may extend in the second direction DR2, and may be arranged along the first direction DR1. For example, each of the plurality of first sensing coils RF includes two pairs of first extension wirings EL1, and the two pairs of first extension wirings EL1 extend parallel or substantially parallel to each other in the second direction DR2. Among the two pairs of first extension wirings EL1, one pair of first extension wirings EL1 may be closer to the non-active area NAA on the upper side than the other pair of first extension wirings EL1. Hereinafter, for convenience, one of the first sensing coils RF will be described in more detail.
[0185] Two pairs of first extension wirings EL1 may extend through the opening OP. The first extension wirings EL1 may extend from the folded portion FP (e.g., in the folded portion FP) to be bent along the edge of the opening OP. A pair of first extension wirings EL1 may be arranged adjacent to each other in the active area AA, and may extend parallel or substantially parallel to each other in the second direction DR2.

The 1-3rd extension wiring EL1-3 may extend in the second direction DR2 and may be parallel or substantially parallel to the 1-1st extension wiring EL1-1. The 1-3rd extension wiring EL1-3 may be spaced farther from the non-active area NAA on the upper side than the 1-1st extension wiring EL1-1.
[0189] The 1-4th extension wiring EL1-4 may be arranged adjacent to the 1-2nd extension wiring EL1-2.

[0331] The sixth extension wiring EL6 , the sixth connector connection wiring CCL6 , and the sixth connection wiring CL6 may be connected to each other to form a loop.
[0332] When viewed on a plane (e.g., in a plan view), the 2nd-3rd sensing coil CF2-3 and the fourth sensing coil CF4 may cross or intersect each other. The 2nd-3rd sensing coil CF2-3 and the fourth sensing coil CF4 may not be arranged at the same plane as each other (e.g., in the middle or on top). As an example, at a point where the 2nd-3rd sensing coil CF2-3 and the fourth sensing coil CF4 cross or intersect each other, any one of the 2nd-3rd sensing coil CF2-3 and any one of the fourth sensing coil CF4 may be arranged on the lower surface of the third supporting layer GF3 and may be contacted through the contact hole CH (e.g., refer to Fig. 10A For example, any one wiring of each of the 2nd-3rd sensing coil CF2-3 and the fourth sensing coil CF4 may be arranged on the lower surface of the third supporting layer GF3, and may be connected to another wiring of a corresponding one of the 2nd-3rd sensing coil CF2-3 and the fourth sensing coil CF4 through the contact hole CH.
[0333] Reference FIG. 10A to FIG. 13According to one or more embodiments of the present disclosure, the first sensing coil RF, the second sensing coil CF2-1, CF2-2 and CF2-3, the third sensing coil CF3 and the fourth sensing coil CF4 may be arranged at (e.g., in the middle or on) the first layer LY1, the second layer LY2 and the third layer LY3.
[0334] The first sensing coil RF, the second sensing coil CF2-1, CF2-2 and CF2-3, the third sensing coil CF3 and the fourth sensing coil CF4 are arranged in different layers from each other. As an example, the first sensing coil RF may be arranged on (or in) the topmost layer, and the 2-3rd sensing coil CF2-3 may be arranged below the first sensing coil RF. The 2-2nd sensing coil CF2-2 may be arranged below the 2-3rd sensing coil CF2-3 so as not to cross or intersect with the 2-3rd sensing coil CF2-3. The third sensing coil CF3, the fourth sensing coil CF4 and the 2-1st sensing coil CF2-1 may be arranged below the 2-3rd sensing coil CF2-3. In other words, the first sensing coil RF, the second sensing coil CF2-1, CF2-2 and CF2-3, the third sensing coil CF3 and the fourth sensing coil CF4 may be arranged at different layers from each other (e.g., in or on).
[0335] When the first sensing coil RF, the second sensing coils CF2-1, CF2-2 and CF2-3, the third sensing coil CF3 and the fourth sensing coil CF4 are arranged at different four layers (eg, middle or upper), the digitizer DGT (eg, see Fig. 9 ) may be increased. When the thickness of the digitizer DGT is increased and the display device DD (see, for example, Figure 1 ) is folded, compressive stress may be applied to the upper surface of the digitizer DGT, or tensile stress may be applied to the lower surface of the digitizer DGT. Accordingly, cracks may occur in the digitizer DGT. Therefore, the folding reliability of the display device DD may be deteriorated.
[0336] However, the first sensing coil RF and the 2-1st sensing coil CF2-1 may be arranged at the first layer LY1 (e.g., in the middle or on top), the 2-2nd sensing coil CF2-2 and the third sensing coil CF3 may be arranged at the second layer LY2 (e.g., in the middle or on top), and the 2-3rd sensing coil CF2-3 and the fourth sensing coil CF4 may be arranged at the third layer LY3 (e.g., in the middle or on top), so that the plurality of sensing coils RF, CF2-1, CF2-2, CF2-3, CF3, and CF4 may be prevented or substantially prevented from electrically interfering with each other. Digitizer DGT (e.g., see Fig. 9) may include a main connector MCP and a sub-connector SCP. The 2-3rd sensing coil CF2-3 and the fourth sensing coil CF4 arranged at the third layer LY3 (e.g., in the middle or on top) may be connected to the sub-connector SCP. The first sensing coil RF, the 2-1st sensing coil CF2-1, the 2-2nd sensing coil CF2-2 and the third sensing coil CF3 may be connected to the main connector MCP. Multiple sensing coils RF, CF2-1, CF2-2, CF2-3, CF3 and CF4 may be arranged at the first layer LY1, the second layer LY2 and the third layer LY3 (e.g., in the middle or on top) so as not to electrically interfere with each other. Accordingly, the digitizer DGT (e.g., see Fig. 9 ) is reduced in thickness, and therefore, when the display device DD (for example, see Figure 1 ) When the display device DD is folded, the magnitude of the tensile stress and the compressive stress applied to the digitizer DGT can be reduced. Therefore, the possibility of cracks in the digitizer DGT can be reduced, and the folding reliability of the display device DD can be improved.
[0337] In addition, the first sensing coil RF, the second sensing coil CF2-1, CF2-2 and CF2-3, the third sensing coil CF3, and the fourth sensing coil CF4 of the digitizer DGT can be arranged at three layers LY1, LY2, and LY3 (for example, in the middle or on), and therefore, compared with the case where the first sensing coil RF, the second sensing coil CF2-1, CF2-2 and CF2-3, the third sensing coil CF3, and the fourth sensing coil CF4 are arranged at different four layers (for example, in the middle or on), the process operations can be reduced. Therefore, the digitizer DGT can be manufactured more easily.
[0338] According to some embodiments of the present disclosure, the digitizer may be divided into a first non-folding portion, a folding portion, and a second non-folding portion. The digitizer may include a first sensing coil, a second sensing coil, a third sensing coil, and a fourth sensing coil. The first to fourth sensing coils may be laminated in three layers, and therefore, the thickness of the digitizer may be reduced. Accordingly, when the display device is folded, the possibility of cracks occurring in the digitizer may be reduced. Therefore, the folding reliability of the display device may be improved.
[0339] According to some embodiments of the present disclosure, as the sensing coils of the digitizer can be laminated in three layers, the process operations can be reduced. Therefore, the digitizer can be manufactured more easily.
[0340] The foregoing is an explanation of some embodiments of the present disclosure and should not be interpreted as limiting it. Although some embodiments have been described, it will be readily appreciated by those skilled in the art that various modifications are possible in the embodiments without departing from the spirit and scope of the present disclosure.
