[0048] In the following description, for the purpose of explanation, many specific details are set forth in order to provide a thorough understanding of the various exemplary embodiments of the invention. As used herein, an "embodiment" is a non-limiting example of a device or method that adopts one or more of the inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other examples, well-known structures and devices are shown in block diagram form to avoid various exemplary embodiments that are unnecessarily ambiguous. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, construction, and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0049] Unless otherwise stated, the exemplary embodiments shown will be understood as providing exemplary features of varying details of some ways in which the inventive concept can be implemented in practice. Therefore, without departing from the inventive concept, unless otherwise stated, the features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as "elements") of the various embodiments may be further combined, separated, interchanged and / or rearranged.

[0050] The use of cross hatching and / or shading in the accompanying drawings is generally provided to clarify the boundaries between adjacent elements. Thus, unless otherwise specified, the presence or absence of cross hatching or shading does not convey or indicate any preference or demand for the specific material, material properties, size, ratio, commonality between the elements shown and / or any other characteristics, attributes, properties, etc. of the element. In addition, in the accompanying drawings, the size and relative size of the elements may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, a specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described sequence. In addition, the same reference numerals represent the same elements.

[0051] When an element or layer is referred to as being "on", "connected to" or "bound to" another element or layer, the element or layer may be directly on, directly connected to or directly bound to the other element or layer, or there may be intervening elements or layers. However, when an element or layer is referred to as being "directly on", "directly connected to" or "directly bound to" another element or layer, there are no intervening elements or layers. For this purpose, the term "connected" may refer to a physical connection, an electrical connection and / or a fluid connection with or without intervening elements. In addition, the DR1 axis, the DR2 axis and the DR3 axis are not limited to the three axes of a rectangular coordinate system (such as the x-axis, the y-axis and the z-axis) and may be interpreted in a broader sense. For example, the DR1 axis, the DR2 axis and the DR3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ for example. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0052] Although the terms "first," "second," etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Therefore, the first element discussed below may be referred to as the second element without departing from the disclosed teachings.

[0053] Spatially relative terms such as "under," "below," "below," "down," "above," "up," "above," "higher," "side" (e.g., as in "sidewall"), and the like may be used herein for descriptive purposes to describe the relationship of one element to another (or other) element(s) as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, elements described as "under" or "beneath" other elements or features would subsequently be positioned as "above" the other elements or features. Thus, the exemplary term "under" may encompass both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein are interpreted accordingly.

[0054] The terms used herein are for the purpose of describing specific embodiments, and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular "one (kind / person)" and "the (described)" are also intended to include plural forms. In addition, when the term "comprising" and its variations, "including" and / or its variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, elements, components and / or their groups, but one or more other features, integral bodies, steps, operations, elements, components and / or their groups are not excluded from existence or addition. It is also noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms rather than degree terms, and are used to explain the inherent deviations of measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0055] Various exemplary embodiments are described herein with reference to cross-sectional illustrations and / or exploded illustrations as schematic illustrations of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations caused by, for example, manufacturing techniques and / or tolerances are expected. Therefore, the exemplary embodiments disclosed herein should not necessarily be interpreted as being limited to the specific illustrated shapes of the regions, but rather include deviations in shapes caused by, for example, manufacturing. In this manner, the regions shown in the drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and as such are not necessarily intended to be limiting.

[0056] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure is a part. 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 should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0057] Hereinafter, the inventive concept will be explained in detail with reference to the accompanying drawings.

[0058] Figure 1 is an assembled perspective view showing an electronic device EA according to an exemplary embodiment of the present invention. Figure 2 is an exploded perspective view showing an electronic device EA according to an exemplary embodiment of the present invention.

[0059] The electronic device EA may be a device activated in response to an electrical signal. The electronic device EA may include various embodiments. The electronic device EA may be a tablet computer, a notebook computer, a computer, or a smart TV. In this exemplary embodiment, a smart phone will be described as a representative example of the electronic device EA.

[0060] Reference Figure 1 , the electronic device EA may display an image IM through the front surface FS. The front surface FS may include a transmission area TA and a bezel area BZA defined adjacent to the transmission area TA.

[0061] The front surface FS is defined as a surface substantially parallel to that defined by the first direction DR1 and the second direction DR2. The normal direction of the front surface FS (i.e., the thickness direction of the electronic device EA) may indicate a third direction DR3. In the following description, the expression "when viewed in a plan view" may mean a state viewed in the third direction DR3. The front (or upper) surface and the rear (or lower) surface of each layer or each unit are distinguished from each other in the third direction DR3. However, the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 are relative to each other, and therefore, the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 may be changed to other directions (e.g., the reverse direction).

[0062] The electronic device EA may display an image IM through the transmissive area TA. The image IM may include a still image and a moving image. Figure 1 A clock widget and application icons are shown as representative examples of the image IM.

[0063] The transmission area TA may have a quadrilateral shape parallel to each of the first direction DR1 and the second direction DR2. However, this is merely exemplary. The transmission area TA may have various shapes, and the inventive concept should not be particularly limited.

[0064] The frame area BZA may surround the transmission area TA. However, this is merely exemplary. The frame area BZA may be disposed adjacent to only one side of the transmission area TA or may be completely omitted. The electronic device EA according to an exemplary embodiment of the present invention may include various embodiments, and it should not be specifically limited.

[0065] The electronic device EA can sense a user input (or external input) TC applied thereto from the outside. The user input TC may include various forms of external input (such as a part of the user's body, light, heat, or pressure). In addition, the electronic device EA can sense an external input (e.g., a close-range input) applied when in close proximity to or adjacent to the electronic device EA, as well as a touch input.

[0066] In the present exemplary embodiment, the user input TC is shown as a touch operation using the user's hand applied to the front surface FS. However, this is only exemplary. As described above, the user input TC can be provided in various forms, and the electronic device EA can sense the user input TC applied to the side surface or rear surface of the electronic device EA according to the structure of the electronic device EA, and it should not be limited to a specific embodiment.

[0067] Reference Figure 2 , the electronic device EA may include a window 100, a display module 200, a circuit board 300, an electronic module 400, and a housing 500. The window 100 and the housing 500 are combined with each other to define the exterior of the electronic device EA.

[0068] The window 100 may be provided on the display module 200 and may cover the front surface IS of the display module 200. The window 100 may include an optically transparent insulating material. For example, the window 100 may include glass or plastic. The window 100 may have a single-layer structure or a multi-layer structure. For example, the window 100 may have a stacked structure of a plurality of plastic films attached to each other by an adhesive or may have a glass substrate and a stacked structure of a plastic film attached to the glass substrate by an adhesive.

[0069] The window 100 may include a front surface FS exposed to the outside. The front surface FS of the electronic device EA may be defined by the front surface FS of the window 100. The transmission area TA may be an optically transparent area. The transmission area TA may have a shape corresponding to the active area AA defined in the display module 200. For example, the transmission area TA may overlap the entire surface or at least a portion of the active area AA. The image IM displayed through the active area AA of the display module 200 may be viewed from the outside through the transmission area TA.

[0070] The bezel area BZA may have a relatively lower transmittance than that of the transmission area TA. The bezel area BZA may define the shape of the transmission area TA. The bezel area BZA may be defined to be adjacent to the transmission area TA and may surround the transmission area TA.

[0071] The frame area BZA may have a predetermined color. When the window 100 includes a glass substrate or a plastic substrate, the frame area BZA may be a color layer printed or deposited on one surface of the glass substrate or the plastic substrate. Alternatively, the frame area BZA may be formed by coloring a corresponding area of ​​the glass substrate or the plastic substrate.

[0072] The bezel area BZA may cover the non-active area NAA of the display module 200 to prevent the non-active area NAA from being viewed from the outside. However, this is merely exemplary. In the window 100 according to an exemplary embodiment of the present invention, the bezel area BZA may be omitted.

[0073] The display module 200 may include a reference Figure 3 The display panel DP and the sensing unit ISU described. The display panel DP may include a configuration suitable for generating an image IM. The image IM generated by the display panel DP may be viewed from the outside by a user through the transmission area TA. The sensing unit ISU may sense an external input TC applied thereto. As described above, the sensing unit ISU may sense an external input TC provided to the window 100. In this exemplary embodiment, the sensing unit ISU may be described as an input sensing layer.

[0074] According to an exemplary embodiment of the present invention, the front surface IS of the display module 200 may include a first area and a second area adjacent to the first area. The first area may correspond to the module area MA and the active area AA surrounding the module area MA, and the second area may correspond to the non-active area NAA. The active area AA may be activated in response to an electrical signal. The module area MA and the second area may be defined as a non-display area in which the image IM is not displayed.

[0075] The active area AA may be a display area through which the image IM is displayed, and may be a sensing area in which the external input TC is sensed. The transmissive area TA may overlap at least the active area AA. For example, the transmissive area TA may overlap the entire surface or at least a portion of the active area AA. Therefore, the user may view the image IM through the transmissive area TA or may provide the external input TC through the transmissive area TA. However, this is merely exemplary. In the active area AA, the area through which the image IM is displayed and the area in which the external input TC is sensed may be separated from each other. However, the inventive concept should not be limited to or thereby.

[0076] The non-active area NAA may be covered by the border area BZA. The non-active area NAA may be disposed adjacent to the active area AA. The non-active area NAA may surround the active area AA. A driving circuit or a driving wiring may be disposed in the non-active area NAA to drive the active area AA.

[0077] Various signal lines, pads (also called "pads" or "solder pads") PD or electronic devices that provide electrical signals to the active area AA may be disposed in the non-active area NAA. The non-active area NAA may be covered by the border area BZA, and therefore, the non-active area NAA may not be visible from the outside.

[0078] In the present exemplary embodiment, the display module 200 may be assembled in a flat state so that the active area AA and the non-active area NAA face the window 100. However, this is merely exemplary. A portion of the non-active area NAA of the display module 200 may be curved. In this case, a portion of the non-active area NAA may be bent toward the rear surface of the electronic device EA, and thus, the area of ​​the border area BZA is reduced on the front side of the electronic device EA. Alternatively, the display module 200 may have a partially curved shape in the active area AA. In addition, the non-active area NAA may be omitted from the display module 200 according to another exemplary embodiment of the present invention.

[0079] The module area MA may have a relatively high transmittance with respect to the same area compared to the active area AA. When viewed in a plan view, the module area MA may be defined at a position overlapping an electronic module 400 described later.

[0080] At least a portion of the module area MA may be surrounded by the active area AA. In the present exemplary embodiment, the module area MA may be spaced apart from the non-active area NAA. The module area MA may be defined in the active area AA so that the entire edge of the module area MA is surrounded by the active area AA.

[0081] The display module 200 may include a panel hole MH defined through the display module 200 in the module area MA. The panel hole MH may penetrate at least one of the display panel DP and the sensing unit ISU. An edge of the module area MA may be spaced apart from an edge of the panel hole MH and may extend along the edge of the panel hole MH. The edge of the module area MA may have a shape corresponding to the panel hole MH.

[0082] The circuit board 300 may be connected to the display module 200. The circuit board 300 may include a flexible board CF and a main board MB. The flexible board CF may include an insulating film and a conductive wire mounted on the insulating film. The conductive wire may be connected to the pad PD to electrically connect the circuit board 300 to the display module 200.

[0083] In the present exemplary embodiment, the flexible board CF may be bent when assembled. Therefore, the main board MB may be disposed on the rear surface of the display module 200 and may be stably accommodated in the space provided by the housing 500. In the present exemplary embodiment, the flexible board CF may be omitted, and in this case, the main board MB may be directly connected to the display module 200.

[0084] The main board MB may include signal lines and electronic devices not shown. The electronic devices may be connected to the signal lines and may be electrically connected to the display module 200. The electronic devices may generate various electrical signals (e.g., signals used to generate an image IM or signals used to sense an external input TC), or may process sensed signals. A plurality of main boards MB may be provided to correspond to electrical signals to be generated or processed, respectively. However, the inventive concept should not be specifically limited.

[0085] In the electronic device EA according to an exemplary embodiment of the present invention, a driving circuit that provides an electrical signal to the active area AA may be directly mounted on the display module 200. In this case, the driving circuit may be mounted in a chip form or may be coupled to the pixel PX (see FIG. Figure 4A ) are formed together. In this case, the area of ​​the circuit board 300 can be reduced, or the circuit board 300 can be completely omitted. The electronic device EA according to the exemplary embodiment of the present invention may include various embodiments, and the electronic device EA should not be particularly limited.

[0086] The electronic module 400 may be disposed under the window 100. The electronic module 400 may overlap the panel hole MH defined in the module area MA. The electronic module 400 may receive an external input TC transmitted through the module area MA or may provide an output through the module area MA.

[0087] Among the components of the electronic module 400, a receiving unit that receives an external input or an output unit that provides an output may overlap with the module area MA in a plan view. All or a portion of the electronic module 400 may be accommodated in the module area MA or the panel hole MH. According to this exemplary embodiment, since the electronic module 400 is arranged to overlap with the active area AA, the size of the bezel area BZA may be reduced.

[0088] Figure 3 is a cross-sectional view illustrating a display module 200 according to an exemplary embodiment of the present invention.

[0089] Reference Figure 3 , the display panel DP may include a base substrate BS, a circuit element layer DP-CL disposed on the base substrate BS, a display element layer DP-OLED, and an insulating layer TFL.

[0090] According to an exemplary embodiment of the present invention, the display panel DP may be a light-emitting display panel, however, it should not be specifically limited. For example, the display panel DP may be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material.

Among the signal lines included in the display panel DP, the scan lines GL, the data lines DL, and the power lines PL are shown as representative examples. However, these are only exemplary. The display panel DP may further include at least one of a power line, an initialization voltage line, and a light emitting control line, and the inventive concept should not be limited to the specific embodiments.

[0110] The groove pattern GV may be defined in the module area MA. The groove pattern GV may be arranged along the edge of the panel hole MH in a plan view, and in the present exemplary embodiment, the groove pattern GV may have a ring shape surrounding the panel hole MH. However, this is only exemplary.

[0114] Some of the pixels PX connected to the first signal line SL1 may be arranged at the left side relative to the panel hole MH, and the other pixels may be arranged at the right side relative to the panel hole MH.

[0115] The second signal line SL2 may extend in the second direction DR2. The second signal line SL2 may be connected to pixels arranged in the same column along the second direction DR2 among the pixels PX. The second signal line SL2 will be described as corresponding to the data line DL.

[0116] Some of the pixels PX connected to the second signal line SL2 may be arranged at the upper side relative to the panel hole MH, and other pixels may be provided at the lower side relative to the panel hole MH. Therefore, even if some pixels are omitted relative to the panel hole MH, the pixels PX arranged in the same column and connected to the second signal line SL2 may receive data signals through the same data line.

One end of the first portion SP1a may be connected to one first connection pattern BP1, and the other end of the first portion SP1a may be connected to another first connection pattern BP1. The first portion SP1a may be referred to as a trunk portion.

[0155] Each of the second sensing patterns SP2 may have a shape corresponding to that of the first sensing patterns SP1 adjacent thereto. Each of the second sensing patterns SP2 may surround at least two third portions SP1c of each of the first sensing patterns SP1 adjacent thereto.

[0156] The sensing lines SL-T, SL-R1, and SL-R2 may overlap the peripheral region NAR and may be disposed on the second sensing insulating layer IS-IL2. The sensing lines SL-T, SL-R1, and SL-R2 may be formed on the second sensing insulating layer IS-IL2 by the same process as that of the first sensing electrode E1 and the second sensing electrode E2.

[0157] The sensing lines SL-T, SL-R1, and SL-R2 may include first sensing lines SL-T and second sensing lines SL-R1 and SL-R2.

The first sensing pad PD1 may be disposed between the first sub-sensing pad PD2a and the second sub-sensing pad PD2b.

[0158] One ends of the first sensing lines SL-T may be electrically connected to the first sensing electrodes E1 , respectively, and the other ends of the first sensing lines SL-T may be electrically connected to the first sensing pads PD1 , respectively.

[0159] The second sensing lines SL-R1 and SL-R2 may include a first sub-sensing line SL-R1 disposed at a left side relative to the second sensing electrode E2 and a second sub-sensing line SL-R2 disposed at a right side relative to the second sensing electrode E2. The first sensing line SL-T may be disposed between the first sub-sensing line SL-R1 and the second sub-sensing line SL-R2.

[0160] One ends of the first sub sensing lines SL- R1 may be electrically connected to some of the second sensing electrodes E2 , respectively, and the other ends of the first sub sensing lines SL- R1 may be electrically connected to the first sub sensing pads PD2 a , respectively.

[0161] One ends of the second sub sensing lines SL-R2 may be electrically connected to the other second sensing electrodes among the second sensing electrodes E2, respectively, and the other ends of the second sub sensing lines SL-R2 may be electrically connected to the second sub sensing pads PD2b, respectively.

[0162] However, the connection structure of the sensing lines SL-T, SL-R1, and SL-R2 should not be limited to Figure 6 The exemplary embodiments shown in FIG. 1 and may be changed to have various shapes.

[0163] According to an exemplary embodiment of the present invention, each of the sensing lines SL-T, SL-R1, and SL-R2 may have a double-layer structure. Each of the sensing lines SL-T, SL-R1, and SL-R2 may be electrically contacted with an auxiliary sensing line (not shown) disposed on the first sensing insulating layer IS-IL1 through at least one contact hole defined through the second sensing insulating layer IS-IL2. The sensing lines SL-T, SL-R1, and SL-R2 may correspond to a second line portion of the second conductive layer IS-CL2.

[0164] A plurality of auxiliary sensing lines may be disposed to correspond to the sensing lines SL-T, SL-R1, and SL-R2, respectively, and may be disposed on the first sensing insulating layer IS-IL1. The auxiliary sensing lines may correspond to the first line portion of the first conductive layer IS-CL1.

[0165] As described above, since the sensing lines SL-T, SL-R1, and SL-R2 are respectively electrically in contact with the auxiliary sensing lines disposed on different layers from each other, the reliability of the electrical signals transmitted to the sensing electrodes E1 and E2 can be improved. For example, although some of the sensing lines SL-T, SL-R1, and SL-R2 are disconnected, the electrical signals can be transmitted to the sensing electrodes E1 and E2 through the auxiliary sensing lines electrically in contact with the sensing lines SL-T, SL-R1, and SL-R2. Fig. 8A and Figure 8B Describe the details about the above.

[0166] The dummy pattern DMP may be spaced apart from the first sensing pattern SP1 and the second sensing pattern SP2. The dummy pattern DMP may be formed on the second sensing insulating layer IS-IL2 by the same process as that of the first sensing pattern SP1 and the second sensing pattern SP2. Therefore, the dummy pattern DMP may include the same material as that of the first sensing pattern SP1, the second sensing pattern SP2, and the sensing lines SL-T, SL-R1, and SL-R2 and may have the same stacking structure as that of the first sensing pattern SP1, the second sensing pattern SP2, and the sensing lines SL-T, SL-R1, and SL-R2. The dummy pattern DMP may be referred to as an "auxiliary pattern", "additional pattern", "sub-pattern", or "boundary pattern".

[0167] The dummy pattern DMP may include a first pattern DMPa and a second pattern DMPb. The first pattern DMPa may be disposed between the first sensing pattern SP1 and the second sensing pattern SP2. The second pattern DMPb may be disposed between the second sensing patterns SP2. For example, the second pattern DMPb may be disposed between two second sensing patterns SP2 adjacent to each other along the second direction DR2, and thus, the two second sensing patterns SP2 may be spaced apart from each other.

[0168] The second pattern DMPb may include a first boundary pattern MP1 and a second boundary pattern MP2. The first boundary pattern MP1 may have a rhombus shape in a plan view. The second boundary patterns MP2 may be spaced apart from each other and the first boundary pattern MP1 may be interposed between the second boundary patterns MP2.
