[0050] Hereinafter, the embodiments will be described in more detail with reference to the accompanying drawings, in which the same reference numerals always refer to the same elements. However, the present disclosure can be implemented in various different 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, unnecessary processes, elements and techniques 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 stated, the same reference numerals represent the same elements throughout the drawings and written descriptions, and therefore, their redundant descriptions may not be repeated.

[0051] When a specific 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 in the reverse order of the described order.

[0052] In the accompanying drawings, for the sake of clarity, the relative size, thickness and ratio of elements, layers and regions may be exaggerated and / or simplified. For ease of explanation, spatial relative terms such as "below", "below", "below", "below", "above" and "on" may be used herein to describe the relationship between an element or feature and another (some) element or feature as shown in the drawings. It will be understood that, in addition to the orientations depicted in the drawings, spatial relative terms are intended to include different orientations of the device in use or operation. For example, if the device is flipped in the drawings, the elements described as "below", "below" or "below" other elements or features will be oriented to "above" other elements or features. Therefore, the example terms "below" and "below" can include two orientations, above and below. The device can be oriented in other ways (for example, rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should be interpreted accordingly.

[0053] In the drawings, the first direction DR1, the second direction DR2, and the third direction DR3 are not limited to directions corresponding to the three axes of the rectangular coordinate system, and can be interpreted more broadly. 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.

[0054] 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, component, region, layer or part described below may be referred to as a second element, component, region, layer or part without departing from the spirit and scope of the present disclosure.

[0055] 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, it may be directly on, directly connected to, or directly 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, or it may be indirectly electrically connected to the other layer, region, or element 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, it may be the only element or layer between the two elements or layers, or there may also be one or more intervening elements or layers.

[0056] The terms used herein are used to describe the purpose of a particular embodiment, rather than to limit the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form "one" is intended to also include the plural form. It will be further understood that when used in this specification, the terms "include", "comprise" and "have" indicate the existence of the stated features, wholes, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, parts and / or their groups. As used herein, the term "and / or" includes any and all combinations of one or more of the items listed in the relevant list. For example, the statement "A and / or B" means A, B or A and B. Statements such as "at least one of", when located after the element list, modify the entire element list without modifying the individual elements in the list. For example, the statements "at least one of a, b and c" and "at least one of the groups selected from a, b and c" represent 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 their variants.

[0057] As used herein, the terms "substantially," "approximately," and similar terms are used as terms of approximation rather than terms of degree, and are intended to account for the inherent deviations in 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" and "used" may be considered synonymous with the terms "utilizing" and "utilized," respectively.

[0058] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that, unless expressly 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 art and / or this specification, and should not be interpreted in an idealized or overly formal sense.

The electronic device ED may provide an image IM to a user through the display surface DS.

[0061] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA (e.g., adjacent to the display area DA). The display area DA may display an image IM, and the non-display area NDA may not display the image IM. The non-display area NDA may surround the display area DA (e.g., around the periphery of the display area DA). However, the present disclosure is not limited thereto, and the shape of the display area DA and the shape of the non-display area NDA may be variously modified as needed or desired.

[0062] Hereinafter, a direction perpendicular or substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2 may be referred to as a third direction DR3. The third direction DR3 may be the basis for the distinction between the front and rear surfaces of various components. The expressions "when viewed from above a plane" and "in a plan view" as used herein may mean a view of a component in the third direction DR3. Hereinafter, the first to third directions DR1, DR2, and DR3 are directions indicated by the first direction axis to the third direction axis shown in the figures, respectively, and are assigned the same reference numerals as the reference numerals of the first direction axis to the third direction axis.

[0063] The electronic device ED may include a folding area FA and a plurality of non-folding areas NFA1 and NFA2. The non-folding areas NFA1 and NFA2 may include a first non-folding area NFA1 and a second non-folding area NFA2. The folding area FA may be disposed between the first non-folding area NFA1 and the second non-folding area NFA2 in the second direction DR2. In the present embodiment, a foldable electronic device ED is illustrated as an example. However, the present disclosure is not limited thereto. The electronic device ED may be a straight-type electronic device, a rollable electronic device, or a slidable electronic device.

[0064] The electronic device ED can sense the input of the stylus pen STP and the input through the user's body FG. A finger is illustrated as an example of the user's body FG.

[0065] like Figure 1B As shown in , the folding area FA can be folded around a folding axis FX that is parallel or substantially parallel to the first direction DR1. The folding area FA has a desired curvature (e.g., a specific or predetermined curvature) and a curvature radius R1. The electronic device ED can be folded in an inward folding manner so that the first non-folding area NFA1 and the second non-folding area NFA2 face each other and the display surface DS is not exposed to the outside.

[0066] In an embodiment of the present disclosure, the electronic device ED can be folded in an outward folding manner so that the display surface DS is exposed to the outside. In an embodiment of the present disclosure, the electronic device ED can be configured so that the inward folding operation and the outward folding operation are repeatedly performed in the unfolded state. However, the present disclosure is not limited thereto. In an embodiment of the present disclosure, the electronic device ED can be configured to select one of the unfolding operation, the inward folding operation, and the outward folding operation.

[0067] like Figure 1BAs shown in , the distance between the first non-folding area NFA1 and the second non-folding area NFA2 may be equal to or substantially equal to twice the radius of curvature R1. However, the present disclosure is not limited thereto, and as Figure 1C As shown in FIG. 1 , the distance between the first non-folding area NFA1 and the second non-folding area NFA2 may be less than twice the curvature radius R1 . Figure 1B and Figure 1C The state in which the display surface DS is folded inside and the housing HM forming the appearance of the electronic device ED is illustrated (for example, refer to Figure 2 ) may contact each other in distal end regions of the first non-folding area NFA1 and the second non-folding area NFA2.

[0156] Each of the electrodes 2-1SE1 may further include a first middle portion SE1-3. The first middle portion SE1-3 may be disposed adjacent to the pad portions PD2 and PD3. The first middle portion SE1-3 may connect the extension portion 1-1SE1-1 and the extension portion 1-2SE1-2 of the electrode 2-1SE1 to each other. The first middle portion SE1-3 may not be disposed in the upper region. Accordingly, one electrode 2-1SE1 may have an open loop shape that is open on the opposite side. According to an embodiment, the signal line 2-1 (e.g., the second-second signal line) SL1 may be connected to the first middle portion SE1-3.

[0157] According to an embodiment, the first middle portion SE1-3 may be insulated from the electrode 1-1PSE1 and may cross the electrode 1-1PSE1. In a region where the first middle portion SE1-3 and the electrode 1-1PSE1 cross each other, a bridge may be provided in a region where different conductive patterns cross each other. The bridge may constitute a portion of the first conductive pattern.

The electrodes 2-3SE-H may be respectively disposed in the grooves PH defined in the electrodes 1-2PSE2. The electrodes 2-3SE-H may remove noise generated when the input sensor 200 senses the second input using a capacitive method. For example, the noise generated when the input sensor 200 senses the second input using a capacitive method may be removed by calculating the difference between a change in capacitance formed between the electrode 2-1SE1 and the adjacent electrode 2-2SE2 and a change in capacitance formed between the electrode 2-1SE1 and the adjacent electrode 2-3SE-H.

In other words, the driving circuit of the input sensor 200 may scan the electrode 2-1SE1. For example, the driving circuit may sequentially provide the driving signal to the electrode 2-1SE1 through the signal line 2-1SL1 provided in the non-display area NDA. The activation periods of the driving signals applied to the electrode 2-1SE1 may be different from each other.

The difference between the amount of change in capacitance detected by the electrode 2-2SE2 and the amount of change in capacitance detected by the electrode 2-3SE-H may be obtained by the differential amplifier AM. Accordingly, the sensing coordinates (e.g., only the pure sensing coordinates) other than the noise value generated in the input sensor 200 may be obtained during the second operation period. The sensing coordinates may be the value of the capacitance detected by the user's body FG (e.g., reference Figure 1A) input.
