     DETAILED DESCRIPTION 
     In the specification, it will be understood that when an element (or a region, a layer, a portion, or the like) is referred to as being “on”, “connected to” or “coupled to” another element, it can be directly disposed on, connected or coupled to another element mentioned above, or intervening elements may be disposed therebetween. 
     Like numbers refer to like elements throughout. Also, in the drawings, the thicknesses, ratios, and dimensions of the elements are exaggerated for effective description of the technical contents. 
     The term “and/or” includes one or more combinations which can be defined by the associated elements. 
     Although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the invention. The singular forms include the plural forms as well, unless the context clearly indicates otherwise. 
     Also, terms such as “below”, “lower”, “above”, and “upper” may be used to describe the relationships of the components illustrated in the drawings. These terms have a relative concept and are described on the basis of the directions indicated in the drawings. 
     “About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). The term “about” can mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value, for example. 
     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 the disclosure belongs. It will be further 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 will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. A term “module” or “unit” may mean a circuit or a processor, for example. 
     It will be understood that the term “includes” or “comprises”, when used in this specification, specifies the presence of stated features, integers, steps, operations, elements, components, or a combination thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof. 
     Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings. 
       FIGS. 1A and 1B  are perspective views of an embodiment of an electronic apparatus according to the invention.  FIGS. 2A and 2B  are perspective views of an embodiment of an electronic apparatus according to the invention.  FIG. 2C  is a plan view of an embodiment of an electronic apparatus according to the invention.  FIGS. 1A and 1B  illustrate an electronic apparatus  1000  in an unfolded state, and  FIGS. 2A to 2C  illustrate the electronic apparatus  1000  in a folded state. Hereinafter, an embodiment of the invention will be described with reference to  FIGS. 1A to 2C . 
     Referring to  FIGS. 1A and 1B , the electronic apparatus  1000  may be an apparatus activated in response to an electrical signal. In an embodiment, the electronic apparatus  1000  may be a mobile phone, a tablet personal computer (“PC”), a vehicle navigation unit, a game console, or a wearable apparatus, for example, but the invention is not limited thereto. In  FIGS. 1A and 1B , the electronic apparatus  1000  is illustrated as a mobile phone. 
     The electronic apparatus  1000  may display an image and sense an external input. The electronic apparatus  1000  may display an image through an active area AA. In the electronic apparatus  1000  illustrated in  FIGS. 1A and 1B , the active area AA may include a plane defined by a first direction DR 1  and a second direction DR 2 . 
     A thickness direction of the electronic apparatus  1000  may be parallel to a third direction DR 3  that crosses the first direction DR 1  and the second direction DR 2 . Thus, a front surface (or a top surface) and a rear surface (or a bottom surface) of members constituting the electronic apparatus  1000  may be defined by the third direction DR 3 . 
     The electronic apparatus  1000  may sense an external input applied from the outside. The external input may be an input of a user. The input of the user may include various types of inputs such as a portion of the user&#39;s body, an electromagnetic instrument (e.g., electromagnetic pen PN), light, heat, or pressure. 
     The electronic apparatus  1000  may sense a plurality of external inputs. In an illustrated embodiment of  FIG. 1A , a user&#39;s hand TC is illustrated as the external inputs, for example. The electronic apparatus  1000  may sense the input position or intensity of the user&#39;s hand TC through capacitance or impedance changed by the user&#39;s hand TC. 
     Also, in an illustrated embodiment of  FIG. 1B , an electromagnetic pen PN is illustrated as the external inputs, for example. However, the invention is not limited thereto, and the external inputs may include various other instruments. The electronic apparatus  1000  may sense the input position or intensity of the electromagnetic pen PN through electro magnetic resonance (“EMR”) due to an electromagnetic induction generated between magnetic field generated inside the electronic apparatus  1000  and the electromagnetic pen PN. 
     Referring to  FIGS. 2A and 2C , the electronic apparatus  1000  may be folded. In the embodiment, the electronic apparatus  1000  may be folded about a folding axis FX extending in parallel to the second direction DR 2 . 
     The folding axis FX is illustrated as extending in the second direction DR 2  in  FIGS. 2A and 2B , but the invention is not limited thereto. In an embodiment, the folding axis FX may extend in a direction parallel to the first direction DR 1 , for example. In this case, a first area NFA 1 , a folding area FA, and a second area NFA 2  may be arranged in this order in the second direction DR 2 . 
     The active area AA may include a first area NFA 1 , a folding area FA, and a second area NFA 2 , which are arranged in this order in the first direction DR 1 . The folding area FA may be an area that forms a flat or curved surface with respect to the folding axis FX according to folding operation of the electronic apparatus  1000 . The first area NFA 1  and the second area NFA 2  may be an area of which a shape is maintained flat according to the folding operation of the electronic apparatus  1000 . Only the positions of the first area NFA 1  and the second area NFA 2  are moved according to the folding operation of the electronic apparatus  1000 , but shape deformation thereof does not occur. 
     As illustrated in  FIG. 2A , when the electronic apparatus  1000  is folded, the folding area FA may form a curved surface concavely curved toward the folding axis FX, and the first area NFA 1  and the second area NFA 2  may face each other. Thus, the active area AA may not be exposed to the outside in a completely folded state, and this state may be referred to as in-folding. 
     In an alternative embodiment, as illustrated in  FIGS. 2B and 2C , when the electronic apparatus  1000  is folded, the folding area FA may form a curved surface convexly curved toward the folding axis FX. Thus, the first area NFA 1  and the second area NFA 2  may display images in directions opposite to each other in a completely folded state, and this state may be referred to as out-folding. Accordingly, in the completely out-folded state as illustrated in  FIG. 2C , the first area NFA 1  may not be exposed from a location where the second area NFA 2  is viewed. 
     In the embodiment, the electronic apparatus  1000  may be unfolded or folded about the folding axis FX and is illustrated as being in-folded or out-folded when folded. However, this is merely an example, and the operation of the electronic apparatus  1000  is not limited thereto. In an embodiment, the electronic apparatus  1000  may be folded such that only in-folding is possible or only out-folding is possible, for example. The electronic apparatus  1000  in an embodiment of the invention may be designed to various shapes as long as it is foldable about the folding axis FX, and is not limited to any particular embodiment. 
     Here, the embodiment having one folding area is illustrated in  FIGS. 1A to 2C , but the number of folding areas is not limited thereto. In an embodiment, the electronic apparatus  1000  may include three or more areas and a plurality of folding areas each of which is disposed between the neighboring areas, for example. 
     Also, the electronic apparatus  1000  in the embodiment of the invention may provide sensing areas, which are different depending on types of external inputs. In an embodiment, an input of the user&#39;s hand TC may be sensed over the entire surface of the active area AA, for example. An input of the electromagnetic pen PN may be sensed on only a portion of the active area AA. An input of the electromagnetic pen PN may be sensed on regions except for the folding area FA in the active area AA, in particular, on the first area NFA 1  and the second area NFA 2 . In an embodiment of the invention, the electronic apparatus  1000  is designed such that the folding area FA is excluded from the sensing areas for the electromagnetic pen PN, and thus it is possible to prevent sensing failures of the electromagnetic pen PN in the foldable electronic apparatus. This will be described in detail later. 
     Also, although not illustrated, the active area AA may overlap at least one electronic module. In an embodiment, the electronic modules may include a camera module, a proximity luminance sensor, or the like, for example. The electronic modules may receive an external input transmitted through the active area AA or provide an output through the active area AA. The portions of the active area AA overlapping the camera module, the proximity luminance sensor, or the like may have higher transmittance than the other portions of the active area AA. Thus, the areas where the plurality of electronic modules is to be disposed may not be provided in a peripheral area NA adjacent to the active area AA. As a result, the area ratio of the active area AA to the entire surface of the electronic apparatus  1000  may increase. 
       FIG. 3A  is an exploded perspective view of an embodiment of an electronic apparatus according to the invention.  FIG. 3B  is a block diagram of the electronic apparatus illustrated in  FIG. 3A .  FIG. 3A  schematically illustrates an exploded perspective view of the electronic apparatus  1000  of  FIG. 1A , and even some components omitted in  FIG. 3A  are illustrated as blocks in  FIG. 3B . Hereinafter, an embodiment of the invention will be described with reference to  FIGS. 3A and 3B . 
     As illustrated in  FIG. 3A , the electronic apparatus  1000  may include an electronic panel  100 , a sensing module  200 , a support plate  300 , a window  400 , and a lower protective member  500 . 
     The electronic panel  100  may be flexible panel. Accordingly, the electronic panel  100  may be rolled entirely, or folded or unfolded about a folding axis FX (refer to  FIGS. 2A and 2B ). The electronic panel  100  may include a display panel  110  and an input sensor  120 . 
     The display panel  110  generates an image. The display panel  110  may be a light emitting-type display panel, but is not particularly limited thereto. In an embodiment, the display panel  110  may be an organic light emitting display panel or a quantum-dot light emitting display panel, for example. A light emitting layer of the organic light emitting display panel may include an organic light emitting material. A light emitting layer of the quantum-dot light emitting display panel may include quantum dots, quantum rods, or the like. Hereinafter, the display panel  110  is described as the organic light emitting display panel. 
     The display panel  110  may include a plurality of pixels (not shown). Each of the pixels may include at least one transistor and a display element electrically connected to the transistor. Each of the display elements displays light to create an image. The active area AA may be a region in which the display elements are arranged. 
     The display element may be a light emitting element that includes a liquid crystal capacitor, an electrophoretic capacitor, or a light emitting element layer. The light emitting element may be an organic light emitting element including the organic layer or a quantum-dot light emitting element including the quantum dots. However, this is merely described as an example. The display panel  110  may include various types of pixels as long as they display an image, and is not limited to any particular embodiment. 
     The input sensor  120  is disposed on the display panel  110 . The input sensor  120  may sense an external input. In the embodiment, the input sensor  120  may sense a signal transmitted from the user&#39;s hand TC (refer to  FIG. 1A ). The input sensor  120  may sense the positions and/or intensities of the user&#39;s hand TC applied over the entire surface of the active area AA. However, this is merely described as an example. The input sensor  120  may sense various types of inputs, and is not limited to any particular embodiment. 
     The input sensor  120  may be disposed directly on the display panel  110 . In an embodiment of the invention, the input sensor  120  may be formed or disposed on the display panel  110  through a continuous process. That is, the input sensor  120  may be provided directly on the display panel  110  without a coupling member such as a separate adhesive film. However, the invention is not limited thereto, and the input sensor  120  may be coupled to the display panel  110  with a coupling member such as an adhesive film therebetween. In this case, the input sensor  120  is manufactured through a process independent of the display panel  110  and then may be coupled to the top surface of the display panel  110  through an adhesive film. 
     The sensing module  200  may be disposed between the electronic panel  100  and the support plate  300 . The sensing module  200  may sense an external input different from an external input sensed by the electronic panel  100 . In an embodiment, the sensing module  200  may sense a signal transmitted by the electromagnetic pen PN (refer to  FIG. 1B ), for example. That is, in the embodiment, the input sensor  120  disposed on the display panel  110  may sense the external input from the user&#39;s hand TC and the sensing module  200  disposed between the electronic panel  100  and the support plate  300  may sense the external input from the electromagnetic pen PN. 
     The sensing module  200  may include a first sensor  210  and a second sensor  220 . Each of the first sensor  210  and the second sensor  220  may have the same structure and may be driven in the same manner. In the embodiment, each of the first sensor  210  and the second sensor  220  is illustrated as being driven in a manner using EMR through electromagnetic induction. However, this is merely described as an example. The first sensor  210  and the second sensor  220  may have structures different from each other or may be driven in different manners, but are not limited to any particular embodiment. 
     The first sensor  210  and the second sensor  220  may be disposed spaced apart from each other with a folding area FA therebetween. The first sensor  210  and the second sensor  220  may be spaced apart from each other in a direction crossing the folding axis FX, that is, in a first direction DR 1 . 
     The first sensor  210  may be disposed overlapping a first area NFA 1 , and the second sensor  220  may be disposed overlapping a second area NFA 2 . The first sensor  210  may sense the position or intensity of the electromagnetic pen PN applied to the first area NFA 1 . The second sensor  220  may sense the position or intensity of the electromagnetic pen PN applied to the second area NFA 2 . 
     In an embodiment of the invention, the electronic apparatus  1000  may sense external inputs which are input in various forms, and thus the utilization of the electronic apparatus  1000  may increase. Also, each of the first sensor  210  and the second sensor  220  includes a plurality of digitizers and may be disposed not overlapping the folding area FA. 
     The sensing module  200  is not disposed in the folding area FA in which shape deformation occurs due to the folding of the electronic apparatus  1000 . That is, in the embodiment, the folding area FA may be an area displaying an image but not sensing the external input from the electromagnetic pen PN. Also, the folding area FA in the embodiment may be an area sensing the external input from the user&#39;s hand TC but not sensing the external input from the electromagnetic pen PN. That is, the folding area FA may be an area in which the pixels or the input sensor  120  do not overlap the sensing module  200  in a plan view. 
     In an embodiment of the invention, the sensing module  200  is not allowed to overlap the folding area FA, and thus it is possible to prevent damages to the sensing module  200  due to stress caused by the folding of the electronic apparatus  1000 . Therefore, the reliability of the electronic apparatus  1000  may be improved. Also, the sensing module  200  does not need to secure flexibility, and thus a degree of freedom in designing the sensing module  200  may be improved. 
     The support plate  300  is disposed below the sensing module  200  to support the electronic panel  100  and the sensing module  200 . The support plate  300  may have a plate shape. In an embodiment, as illustrated in  FIG. 3A , the support plate  300  may be provided in the form of a single body plate having a shape corresponding to the shape of the electronic panel  100 , for example. Here, this is merely illustrated as an example. The support plate  300  may be provided as divided into two or more parts respectively overlapping the first area NFA 1  and the second area NFA 2 , but is not limited to any particular embodiment. 
     The support plate  300  may include a material having higher modulus than that of the electronic panel  100 . In an embodiment, the support plate  300  may include metal, for example. In an embodiment, the support plate  300  may include stainless steel, aluminum, or an alloy thereof, for example. The support plate  300  includes metal and thus may serve as a heat dissipating layer as well as support the electronic panel  100 . However, this is merely described as an example. The support plate  300  may include various materials as long as it may support the electronic panel  100 , and is not limited to any particular embodiment. 
     A plurality of openings HH may be defined in the support plate  300  in an area overlapping the folding area FA. Each of the openings HH is defined as passing through the support plate  300 . The openings HH may be arranged spaced apart from each other. The openings HH may be arranged, for example, in a zigzag form, but the invention is not limited thereto. 
     Also, the openings HH may be groove patterns recessed from the top surface or the bottom surface of the support plate  300 . The thickness of the folding area FA of the support plate  300  is reduced by the openings HH, and thus the flexibility of the support plate  300  in the folding area FA may be improved. 
     The window  400  is disposed on the electronic panel  100  to protect the electronic panel  100 . The external input is substantially provided on the window  400 . The window  400  may include an optically transparent insulating material. Accordingly, an image generated in the electronic panel  100  may be easily recognized by a user after passing through the window  400 . 
     For example, the window  400  may include thin film glass or a synthetic resin film. In an embodiment, when the window  400  includes the thin film glass, the thickness of the window  400  may be about 100 micrometers (μm) or less and, for example, about 30 μm, but the thickness of the window  400  is not limited thereto. In an embodiment, when the window  400  includes the synthetic resin film, the window  400  may include a polyimide (“PI”) film or a polyethylene terephthalate (“PET”) film. 
     The window  400  may have a multilayer structure or a single layer structure. In an embodiment, the window  400  may include a plurality of synthetic resin films coupled by an adhesive, or a glass substrate and a synthetic resin film which are coupled to each other by an adhesive, for example. The window  400  may include a flexible material. Accordingly, the window  400  may be folded or unfolded about the folding axis FX. That is, when the shape of the electronic panel  100  is deformed, the shape of the window  400  may also be deformed according to the shape of the electronic panel  100 . 
     The window  400  relieves external impact as well as allows an image from the electronic panel  100  to pass therethrough, thus preventing the electronic panel  100  from being damaged or malfunctioning due to the external impact. The external impact is a force from the outside expressible as pressure, stress, or the like, and refers to a force that causes defects to the electronic panel  100 . 
     Here, although not illustrated, the electronic apparatus  1000  may further include a protective layer disposed on the window  400 . The protective layer may be a layer for improving impact resistance of the window  400  and preventing scattering when the window  400  is broken. The protective layer may include at least one selected from among a urethane-based resin, an epoxy-based resin, a polyester-based resin, a polyether-based resin, an acrylate-based resin, an acrylonitrile-butadiene-styrene (“ABS”) resin, and rubber. In an embodiment of the invention, the protective layer may include at least one of phenylene, PET, PI, polyamide (“PAI”), polyethylene naphthalate (“PEN”), or polycarbonate. 
     Also, although not illustrated, the electronic apparatus  1000  may further include one or more functional layers disposed between the electronic panel  100  and the window  400 . In an embodiment, the functional layer may be an anti-reflection layer for preventing reflection of external light, for example. The anti-reflection layer may prevent elements constituting the electronic panel  100  from being visible from the outside due to the external light which is incident through the front surface of the electronic apparatus  1000 . The anti-reflection layer may include a retarder, a polarizer, or a color filter. 
     The lower protective member  500  is disposed below the support plate  300 . The lower protective member  500  may protect the electronic panel  100 , the sensing module  200 , and the support plate  300 .

The lower protective film  600  may be a colored polyimide film. In an embodiment, the lower protective film  600  may be an opaque yellow film, for example, but the invention is not limited thereto.

       FIG. 5B  illustrates an embodiment of a first sensor  210  included in the sensing module  200 . Referring to  FIG. 5B , the first sensor  210  may include a plurality of first coils  201  and a plurality of second coils  202 . The first coils  201  may be also referred to as driving coils, and the second coils  202  may be also referred to as sensing coils. 
     The first coils  201  may be arranged spaced apart from each other in a second direction DR 2 , and each may extend in a first direction DR 1 . The second coils  202  may be arranged spaced apart from each other in the first direction DR 1 , and each may extend in the second direction DR 2 . 
     In order to sense the electromagnetic pen PN (refer to  FIG. 1B ), alternate current signals are sequentially provided to first terminals  201   t  of the first coils  201 . The first coils  201  are formed or provided in a closed curve shape.

The second coils  202  may output signals, which sense the induction electromagnetic force discharged from the electromagnetic pen PN, to second terminals  202   t  of the second coils  202 . 
       FIG. 5B  illustrates an embodiment of a configuration of a digitizer, but the invention is not limited thereto. Also, the arrangement relationship between the first coils  201  and the second coils  202  is not limited to that illustrated in  FIG. 5B  and may be modified diversely. 
     Referring back to  FIG. 5A , the first sensor  210  and the second sensor  220  may be disposed spaced apart from each other with a folding area FA therebetween. One side surface  210 _S of the first sensor  210  and one side surface  220 _S of the second sensor  220  may face each other with the folding area FA therebetween in a first direction DR 1 . 
     In an embodiment of the invention, the electronic apparatus  1000  is provided with the first and second sensors  210  and  220  spaced apart from each other and thus may be designed such that the sensing module  200  does not overlap the folding area FA. Accordingly, it is possible to prevent the first conductive layer  212  or the second conductive layer  215  having the coils for sensing the electromagnetic pen PN from being damaged due to the folding. Therefore, it is possible to prevent damages due to folding stress such as cracks of the sensing module  200  and improve the reliability of the electronic apparatus  1000 . 
       FIGS. 6A to 6C  are plan views of an embodiment of an electronic apparatus according to the invention.  FIGS. 6A to 6C  illustrate utilization of an embodiment of an electronic apparatus  1000  according to various external inputs. 
     As illustrated in  FIG. 6A , when the input of the electromagnetic pen PN is provided to the electronic apparatus  1000 , the input of the electromagnetic pen PN is sensed through a first area NFA 1  or a second area NFA 2 , but is not sensed in a folding area FA. Thus, the electronic apparatus  1000  in an embodiment of the invention may provide the folding area FA with an image that does not require an input of the electromagnetic pen PN. 
     In particular, the electronic apparatus  1000  displays images such that an image IM 3 A displayed on the folding area FA is different from an image IM 1 A displayed on the first area NFA 1  or an image IM 2 A displayed on the second area NFA 2 . The image IM 1 A displayed on the first area NFA 1  or the image IM 2 A displayed on the second area NFA 2  may be an image such as a note that requires an input of the electromagnetic pen PN, but the image IM 3 A displayed on the folding area FA may be a spring image that connects notes. 
     Accordingly, as illustrated in  FIG. 6A , a user provides the input of the electromagnetic pen PN to the second area NFA 2  that requires the input of the electromagnetic pen PN such that a pen image IM_P 11  is displayed on the second area NFA 2 . Subsequently, as illustrated in  FIG. 6B , an image IM 2 B displayed on the second area NFA 2  by an operation of a user&#39;s touch TC is displayed as an image in which a page is being turned over. An image IM 3 B displayed on the folding area FA may be still maintained as the spring image. 
     Subsequently, as illustrated in  FIG. 6C , a note image on the next page may be provided in an active area AA. The image IM 1 C displayed on the first area NFA 1  or the image IM 2 C displayed on the second area NFA 2  may be an image of a note that requires an input of the electromagnetic pen PN, but the image IM 3 C displayed on the folding area FA may be still maintained as the spring image. 
     Accordingly, the input of the electromagnetic pen PN may be naturally guided and provided to the first area NFA 1  or the second area NFA 2 , not the folding area FA. The user provides, through the electromagnetic pen PN, an input of the electromagnetic pen PN to the second area NFA 2  which senses the input of the electromagnetic pen PN, and the electronic apparatus  1000  may output a pen image IM_P 12  corresponding to the input. 
     The electronic apparatus  1000  in an embodiment of the invention may display, on the folding area FA, an image that does not require an input of the electromagnetic pen PN, and thus a sensing area for sensing the electromagnetic pen PN may not be provided in the folding area FA. Accordingly, although the electronic apparatus  1000  includes the sensing module  200  (refer to  FIG. 3A ) which does not overlap the folding area FA, a natural user environment may be provided. 
       FIGS. 7A to 7D  are plan views of an embodiment of an electronic apparatus according to the invention.  FIGS. 7A to 7D  illustrate utilization of an electronic apparatus  1000  according to various external inputs. Here, the same reference numerals may be given to the same components as those illustrated in  FIGS. 6A to 6C , and their duplicated descriptions will be omitted. 
     As illustrated in  FIG. 7A , an image IM 31 A displayed on a folding area FA may be an image for selecting a pen. An image IM 11 A displayed on a first area NFA 1  or an image IM 21 A displayed on a second area NFA 2  may be an image such as plain note. A user provides an input of the electromagnetic pen PN to the second area NFA 2  on which the note image determined as enabling the input of the electromagnetic pen PN is displayed, and an electronic apparatus  1000  outputs a pen image IM_P 21  corresponding to the input. 
     Subsequently, as illustrated in  FIG. 7B , an image IM 31 B displayed on the second area FA between an image IM 11 B and an image IM 21 B is touched by a user&#39;s hand TC, and a pen feature may be selected. A sensing area for sensing the user&#39;s hand TC is provided over the entire surface of an active area AA in the electronic apparatus  1000 . Thus, the folding area FA may sense information which is input through the user&#39;s hand TC instated of the electromagnetic pen PN. 
     Subsequently, as illustrated in  FIG. 7C , the input of the electromagnetic pen PN is provided to the second area NFA 2 , and a new pen image IM_P 22  may be provided in an image IM 21 C. The new pen image IM_P 22  is output thicker than the previous pen image IM_P 21 . That is, when the pen is selected, thickness setting of a pen point might be changed. The previous images IM 11 B and IM 31 B may be maintained in images IM 11 C and IM 31 C, respectively. 
     Also, as illustrated in  FIG. 7D , the input of the electromagnetic pen PN is provided to the second area NFA 2 , and a new pen image IM_P 23  may be provided. The new pen image IM_P 23  is output in a color different from that of the previous pen image IM_P 21 . That is, when the pen is selected, pen color setting might be changed. 
     In an embodiment of the invention, the electronic apparatus  1000  provides the folding area FA with the image that does not require the input of the electromagnetic pen PN and provides the first area NFA 1  and the second area NFA 2  with the images that require the input of the electromagnetic pen PN, and thus the input of the electromagnetic pen PN to the folding area FA may be naturally removed. Also, the image is provided in which the folding area FA may be utilized by the external input such as the user&#39;s hand TC different from the electromagnetic pen PN, and thus the utilization of the electronic apparatus  1000  capable of sensing various external inputs may be improved. 
       FIGS. 8A to 8C  are plan views of an embodiment of an electronic apparatus according to the invention.  FIGS. 8A to 8C  illustrate utilization of an electronic apparatus  1000  according to various external inputs. Here, the same reference numerals may be given to the same components as those illustrated in  FIGS. 6A to 6C , and their duplicated descriptions will be omitted. 
     As illustrated in  FIGS. 8A to 8C , an image IM 32 A displayed on a folding area FA may be a scroll bar image IM_SCR. Images IM 12 A and IM 22 A displayed on a first area NFA 1  and a second area NFA 2 , respectively, may be note images to which information is input by an electromagnetic pen PN. An input of the electromagnetic pen PN is provided in the second area NFA 2 , and a pen image IM_P 31  corresponding to the input is displayed on the second area NFA 2 . 
     Subsequently, as illustrated in  FIG. 8B , when a user&#39;s hand TC operates to move the scroll bar image IM_SCR downward, an image in which the scroll bar image IM_SCR is moving downward according to the operation may be displayed on the folding area FA. 
     Subsequently, as illustrated in  FIG. 8C , images IM 12 C and IM 22 C corresponding to the movement of a scroll bar image IM_SCR shown in an image IM 32 C are displayed on the first area NFA 1  and the second area NFA 2 , respectively, and the scroll bar image IM_SCR is displayed on the folding area FA. The input of the electromagnetic pen PN may be naturally guided to the first area NFA 1  or the second area NFA 2 , and a pen image IM_P 32  corresponding to the input of the electromagnetic pen PN may be displayed on the second area NFA 2 . 
     In an embodiment of the invention, the electronic apparatus  1000  provides the folding area FA with the image that does not require the input of the electromagnetic pen PN and provides the first area NFA 1  and the second area NFA 2  with the images that require the input of the electromagnetic pen PN, and thus the input of the electromagnetic pen PN to the folding area FA may be naturally removed. Also, the image is provided in which the folding area FA may be utilized by the external input such as the user&#39;s hand TC different from the electromagnetic pen PN, and thus the utilization of the electronic apparatus  1000  capable of sensing various external inputs may be improved. 
     According to the embodiment of the invention, it is possible to prevent damages to the sensing module due to folding stress. Also, in the embodiment of the invention, it is possible to improve utilization of the electronic apparatus because various types of external inputs may be sensed. 
     Although described with reference to an embodiment of the invention, it will be understood that various changes and modifications of the invention may be made by one ordinary skilled in the art or one having ordinary knowledge in the art without departing from the spirit and technical field of the invention as hereinafter claimed.
