[0046] In this disclosure, when a component (or region, layer, part, etc.) is described as being “on”, “connected to”, or “joined to” another component, it means that the component may be directly on, directly connected to, or joined to the other component, or that a third component may be present between the component and the other component.
[0047] The same reference numerals refer to the same elements. Additionally, in the accompanying drawings, the thickness, proportions, and dimensions of parts are exaggerated for the sake of effective description.
[0048] "And / or" includes all combinations of one or more combinations defined by the relevant component.
[0049] It will be understood that the terms "first" and "second" are used herein to describe various components, but these components should not be limited by these terms. The terms above are used only to distinguish one component from another. For example, a first component may be referred to as a second component without departing from the scope of the inventive concept of this disclosure, and vice versa. Unless the context clearly indicates otherwise, singular expressions include plural expressions.
[0050] Additionally, terms such as “lower,” “lower side,” “upper,” and “upper side” are used to describe the relationships of the configurations shown in the accompanying drawings. These terms are described as relative concepts based on the directions shown in the drawings and can vary depending on the orientation and configuration of the drawings.
[0051] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Furthermore, terms defined in commonly used dictionaries shall be interpreted as having a meaning consistent with that in the context of the relevant art, and not as having an idealized or overly formal meaning, unless they are explicitly defined herein.
[0052] In various embodiments of the inventive concept, the terms "comprising" or "including" specify attributes, areas, fixed quantities, steps, processes, elements, and / or components, but do not exclude other attributes, areas, fixed quantities, steps, processes, elements, and / or components. Various exemplary embodiments of the inventive concept will be described below with reference to the accompanying drawings.

Figure 2A This is an exploded perspective view of an electronic device according to an embodiment of the present invention. Figure 2B yes Figure 2A A block diagram of an electronic device is shown. Figure 3 It is shown schematically. Figure 2A The plan view of region XX′ is shown in the figure. Figure 4A This is a plan view of the input detection component according to an embodiment of the present invention. Figure 4B It is along Figure 4A A cross-sectional view of an electronic device taken by line I-I'. Figure 5A This is an enlarged view of a portion of an electronic device according to an embodiment of the present invention. Figure 5B It is along Figure 5A The cross-sectional view taken along line II-II' is shown in the figure. Reference will be made below. Figures 1 to 5B An electronic device based on the present invention is described.
[0054] refer to Figure 1 and Figure 2A An electronic device EA displays an image IM on a plane defined by a first direction D1 and a second direction D2, directed towards a third direction D3. The electronic device EA includes a window layer WM, a display module DM, an electronic module ID, and a cover shell EDC. The display module DM, according to the present invention, includes a display member DU and an input detection member TU. According to one embodiment, the display module DM includes at least one module hole HM defined by a front surface IS and a rear surface opposite to the front surface IS. Figure 2A The image shows a single module hole HM as an example. In other embodiments, the display module DM may include two or more module hole HMs corresponding to a respective electronic module ID.
[0055] A window layer WM is disposed on the display module DM to cover the front surface IS of the display module DM. The window layer WM includes a front surface FS exposed to the outside. The image IM displayed on the display component DU of the display module DM is viewed from the outside through the front surface FS of the window layer WM.
[0056] The window layer (WM) can have a single-layer or multi-layer structure. For example, the window layer (WM) can have a stacked structure of multiple plastic films bonded together by an adhesive, or it can have a stacked structure of a glass substrate and plastic films bonded together by an adhesive. The window layer (WM) can be optically transparent. For example, the window layer (WM) can include glass or plastic.
[0057] The front surface FS of the window layer WM can be divided into a transmissive region TA and a border region BZA. The transmissive region TA can correspond to the area that transmits light from the display module DM. The transmissive region TA can have a shape corresponding to the active region AA of the display module DM. For example, the transmissive region TA overlaps with all or at least a portion of the active region AA. Therefore, the image IM displayed in the active region AA of the display module DM can be visually identified through the transmissive region TA.
[0058] The border region BZA may correspond to a region with lower light transmittance compared to the transmission region TA. The border region BZA may define the shape of the transmission region TA. The border region BZA is adjacent to the transmission region TA, and according to an embodiment, the border region BZA may have a closed-line shape surrounding the transmission region TA. However, the inventive concept is not limited to this embodiment, and the border region BZA may be disposed only on one or more selected sides of the transmission region TA, or on one or more portions of one or more selected sides. In some embodiments, the border region BZA may be omitted. It is understood that the inventive concept of this disclosure is not limited to any particular embodiment.
[0059] The border area BZA can have a predetermined color. The border area BZA covers the peripheral area NAA of the display module DM to prevent the peripheral area NAA from being visually identified from the outside. For example, if light generated by the display component DU of the display module DM leaks into the peripheral area NAA, the light leaking into the border area BZA can be blocked, thereby preventing the light leaking into the peripheral area NAA from being seen from the outside.
[0060] The display element DU of the display module DM displays the image IM on the front surface IS of the display module DM. The front surface IS can be divided into an active region AA, a hole region PA, and a peripheral region NAA. The image IM is displayed in the active region AA. The peripheral region NAA is adjacent to the active region AA. The active region AA can correspond to the area in which the pixel PX of the display element DU, which will be described later, is disposed.
[0061] According to an embodiment, the hole region PA overlaps with the module hole HM. The hole region PA may correspond to a region at least partially surrounded by the active region AA. Although Figure 2AThe diagram illustrates a shape in which the hole region PA is completely surrounded by the active region AA, but one area of the hole region PA may be surrounded by the active region AA, and the remaining area of the hole region PA may be surrounded by the peripheral region NAA. It is understood that the inventive concept of this disclosure is not limited to any particular embodiment. In this example, the hole region PA overlaps with the module hole HM.
[0062] refer to Figure 2B The power module (PM) provides the power required for the overall operation of the electronic device (EA). The power module (PM) may include a battery module.
[0063] The electronic module ID includes various functional modules used to operate the electronic device EA. The electronic module ID may include a first electronic module EM1 and a second electronic module EM2.
[0064] The first electronic module EM1 can be directly mounted on a motherboard (not shown) that is electrically connected to the display module DM, or it can be mounted on a separate board and electrically connected to the motherboard via a connector (not shown) or the like.
[0065] The first electronic module EM1 may include a control module CM, a wireless communication module TM, an image input module IIM, an audio input module AIM, a memory MM, and an external interface OIP. Some modules may not be mounted on the motherboard, but can be electrically connected to the motherboard via flexible circuit boards or connectors.
[0066] The control module (CM) controls the overall operation of the electronic device (EA). The control module (CM) can be a microprocessor. For example, the control module (CM) activates or deactivates the display module (DM). The control module (CM) can also control other modules, such as the image input module (IIM) and the audio input module (AIM), based on touch signals received through the electronic device (EA).
[0067] The wireless communication module™ can send wireless signals to / receive wireless signals from another device via Bluetooth or Wi-Fi connection. For example, the wireless communication module™ can send / receive voice signals. The wireless communication module™ includes a transmitter TM1 for modulating and transmitting the signal to be transmitted and a receiver TM2 for modulating the received signal.
[0068] The image input module (IIM) processes the image signal and converts it into image data that can be displayed on the display module (DM).
[0069] In recording mode, voice recognition mode, etc., the audio input module AIM receives external sound signals through a microphone and converts the external sound signals into electronic voice data.
[0070] The memory MM can store data received from the wireless communication module TM, the image input module IIM, and the audio input module AIM, and can also delete used data from the memory MM. Additionally, data required for controlling the second electronic module EM2 can be stored in and / or deleted from the memory MM.
[0071] External interface (OIP) serves as an interface to one or more external devices, such as chargers, wired / wireless data ports, and card slots (e.g., memory cards, SIM / UIM cards).
[0072] The second electronic module EM2 may include an audio output module AOM, a light-emitting module LM, a light-receiving module LRM, and a camera module CMM. The modules included in the second electronic module EM2 can be directly mounted on the motherboard, or mounted on a separate substrate and electrically connected to the display module DM and / or electrically connected to the first electronic module EM1 via connectors.
[0073] The audio output module AOM converts audio data received from the wireless communication module TM or stored in the memory MM, and outputs the audio data, for example, using a speaker.
[0074] A light-emitting module (LM) generates and outputs light. The LM can output infrared light. The LM may include LED elements. A light-receiving module (LRM) detects infrared light. The LRM can be activated when a predetermined level or higher of infrared light is detected. The LRM may include a complementary metal-oxide-semiconductor (CMOS) sensor. After the infrared light generated by the LM is output, it is reflected by an external object (e.g., a user's finger or face), and the reflected infrared light can be incident on the LRM. A camera module (CMM) captures an image of the object.
[0075] In particular, Figure 2A The electronic module ID shown can be any one or more modules included in the second electronic module EM2. In this case, the first electronic module EM1 and the remaining modules of the second electronic module EM2 can be located in different positions and are not shown. For example, the electronic module ID can include at least one of the following: audio output module AOM, light emission module LM, light receiving module LRM, and camera module CMM.
[0076] According to one embodiment, the electronic module ID can be inserted into the module hole HM. Alternatively, the electronic module ID can be disposed adjacent to the module hole HM on the rear surface of the display member DU. In one embodiment, only one module included in the electronic module ID may be exposed to the outside through the module hole HM. For example, only the lens included in the camera module CMM may be exposed through the module hole HM. Alternatively, the electronic module ID may be disposed on the rear surface of the display member DU and spaced apart from the display member DU in a cross-sectional view.
[0077] The display component DU according to an embodiment of the present invention includes a module hole HM formed in the active region AA, such that no separate space for the electronic module ID is required in the peripheral region NAA. Therefore, the area of the bezel region BZA can be reduced, thereby enabling an electronic device EA with a narrow bezel. Furthermore, when the electronic module ID is housed in the module hole HM, the electronic device EA can be implemented with a thin form factor.
[0078] Figure 3 The diagram exemplarily illustrates the relationship between pixels PX and module holes HM included in the display component DU of the display module DM.
[0079] According to one embodiment, a pixel PX is disposed in an active region AA of a display module DM. The pixel PX may be spaced apart from and surround an aperture region PA. Although not shown in the figures, pixels PX spaced apart from the aperture regions PA between pixels PX can be connected via signal lines passing through the aperture regions PA to receive the same signal.
[0080] Refer again Figure 2A The cover EDC can be attached to the window layer WM. The cover EDC provides the rear surface of the electronic device EA. The cover EDC is attached to the window layer WM to provide internal space. Figure 2B The display module DM, electronic module ID, and various modules / components shown can be housed within an internal space defined by the cover EDC and window layer WM. The cover EDC can comprise materials with relatively high rigidity. For example, the cover EDC can comprise multiple frames and / or plates made of glass, plastic, or metal. The cover EDC can stably protect the structure of the electronic device EA housed within the internal space from external impacts.
[0081] refer to Figure 2A and Figure 4AAccording to the present invention, an input detection component TU can be disposed on a display component DU. The input detection component TU may include a first detection electrode TE1, a second detection electrode TE2, a first detection trace wiring SL1, and a second detection trace wiring SL2 arranged on a plane. The input detection component TU includes a detection area for detecting external input and a non-detection area adjacent to the detection area. According to one embodiment, the detection area may overlap with an active area AA, and the non-detection area may overlap with a peripheral area NAA.
[0082] The first detection electrode TE1 extends along a first direction D1. Multiple first detection electrodes TE1 may be arranged along a second direction D2. Each first detection electrode TE1 includes multiple first detection sensors SP1 arranged along the first direction D1 and a first connection pattern BP1 disposed between the first detection sensors SP1 to connect adjacent first detection sensors SP1.
[0083] The second detection electrode TE2 can be arranged to be insulated from the first detection electrode TE1. The second detection electrode TE2 extends along a second direction D2. A plurality of second detection electrodes TE2 can be arranged along a first direction D1. The second detection electrode TE2 includes a plurality of second detection sensors SP2 arranged along the second direction D2 and a second connection pattern BP2 disposed between the second detection sensors SP2 to connect adjacent second detection sensors SP2. Each of the first detection electrode TE1 and the second detection electrode TE2 can have a grid shape.
[0084] The input detection component TU detects changes in the mutual capacitance between the first detection electrode TE1 and the second detection electrode TE2 to detect external input, or detects changes in the self-capacitance of each of the first detection electrode TE1 and the second detection electrode TE2 to detect external input. The input detection component TU, according to embodiments of the present invention, can detect external input in various ways and is not limited to any particular embodiment.
[0085] External inputs can include various types of inputs provided to the electronic device EA. Externally applied inputs can be provided in various forms. For example, external inputs can include non-contact external inputs (e.g., hovering) applied near or at a predetermined distance from the electronic device EA, as well as tactile inputs via a part of the human body (e.g., a user's hand). Furthermore, external inputs can take various forms such as force, pressure, and light, and are not limited to any particular form of input.
[0086] A first detection trace SL1 is connected to a corresponding one of the first detection electrodes TE1. A second detection trace SL2 is connected to a corresponding one of the second detection electrodes TE2. The first and second detection traces SL1 and SL2 can extend into the peripheral region NAA. For example, the first and second detection traces SL1 and SL2 can be located in a non-detection area overlapping the peripheral region NAA and are not visible from the outside.
[0087] For ease of description, Figure 4A Only a subset of the first detection trace wiring SL1 and the second detection trace wiring SL2, which are respectively connected to one of the first detection electrode TE1 and the second detection electrode TE2, are shown. For example, Figure 4A The diagram illustrates two first detection trace wirings SL1 connected to both ends of the first detection electrode TE1 located on the far left.
[0088] Simultaneously, according to one embodiment, a first detection electrode TE1 can be connected to two first detection traces SL1. The two first detection traces SL1, connected to one end and the other end of a first detection electrode TE1, can be separately and independently connected to a corresponding detection pad in the detection pad PD1. Therefore, even though the first detection electrode TE1 has a relatively longer length along the first direction D1 compared to the second detection electrode TE2, the electrical signal can be uniformly applied to the entire area. Thus, regardless of the shape and configuration of the first detection electrode TE1, the input detection member TU can provide a uniform external input detection environment across the entire detection area.
[0089] Similarly, the second detection electrode TE2 can also be connected to two second detection trace wirings SL2. In another embodiment, each of the first detection electrode TE1 and the second detection electrode TE2 can be connected to only one detection trace wiring SL1 or SL2. The input detection member TU according to embodiments of the present invention can be driven in various ways and is not limited to any particular embodiment.
[0090] Although not shown in the accompanying drawings, the detection pad PD1 of the input detection component TU can be connected to a touch flexible circuit board (not shown) located on one side of the peripheral area NAA. The touch flexible circuit board can be connected to the main circuit board (not shown). The main circuit board can receive signals from the input detection component TU.
[0091] The electronic device EA according to the present invention includes at least a breakage detection wiring HCD. The breakage detection wiring HCD may be disposed on the same layer as the input detection component TU. The breakage detection wiring HCD is positioned adjacent to the module aperture HM. Furthermore, the breakage detection wiring HCD is spaced apart from the detection electrodes TE1 and TE2 of the input detection component TU. Figure 4A For ease of explanation, the input detection component TU and the breakage detection wiring HCD are shown together.
[0092] A portion of the crack detection wiring HCD can extend to the peripheral area NAA and connect to one of the detection pads PD2. The detection pads PD2 include a first input pad PD-I1, a second input pad PD-I2, a first output pad PD-O1, and a second output pad PD-O2. The detection pads PD2 can be connected to a touch flexible circuit board (not shown) to receive signals from or output signals to the main circuit board (not shown).
[0093] The breakage detection wiring HCD includes a first input trace wiring HCD-I1, a second input trace wiring HCD-I2, a first output trace wiring HCD-O1, and a second output trace wiring HCD-O2. One end of the breakage detection wiring HCD has an opening curve shape surrounding the module via HM, and this end of the breakage detection wiring HCD is connected to one of the first input trace wiring HCD-I1 and the second input trace wiring HCD-I2. One end and the other end of the input trace wiring HCD-I1 and HCD-I2 extending to the peripheral area NAA are respectively connected to the first input pad PD-I1 and the second input pad PD-I2.
[0094] The other end of the break detection wiring HCD also has an open curve shape that connects to the first output trace wiring HCD-O1 and the second output trace wiring HCD-O2. One end and the other end of the output trace wirings HCD-O1 and HCD-O2 extending to the peripheral area NAA are respectively connected to the first output pad PD-O1 and the second output pad PD-O2.
[0095] According to an embodiment, the breakage detection wiring HCD can determine whether at least one of the layers disposed below the breakage detection wiring HCD is broken during the formation of the module via HM. For example, the module via HM is formed after the breakage detection wiring HCD is formed, and a signal is applied to the detection pad PD2 connected to the breakage detection wiring HCD to determine whether at least one of the layers forming the display module DM is broken.
[0096] exist Figure 4AIn the diagram, input trace routings HCD-I1 and HCD-I2 correspond to different portions of a single trace, but are referred to as the first input trace routing HCD-I1 and the second input trace routing HCD-I1 for ease of explanation. Similarly, output trace routings HCD-O1 and HCD-O2 correspond to different portions of a single trace, but are referred to as the first output trace routing HCD-O1 and the second output trace routing HCD-O2.
[0097] When a signal is applied to the first input pad PD-I1, the signal passes through the break detection wiring HCD surrounding the module via hole HM via the first input trace wiring HCD-I1 connected to the first input pad PD-I1. The signal can be transmitted to the first output pad PD-O1 via the first output trace wiring HCD-O1.
[0098] When no breakage occurs in any of the layers below the breakage detection wiring HCD, the signal is transmitted to the first output pad PD-O1. If a breakage occurs in any of the layers below the breakage detection wiring HCD, for example, in at least one of the right side of the input detection component TU and the via region PA in which the first input trace wiring HCD-I1 and the first output trace wiring HCD-O1 are arranged, the signal may not be transmitted to the first output pad PD-O1.
[0099] Furthermore, when a signal is applied to the second input pad PD-I2, the signal passes through the second input trace wiring HCD-I2 connected to the second input pad PD-I2 and then through the break detection wiring HCD surrounding the module hole HM. The signal can be transmitted to the second output pad PD-O2 via the second output trace wiring HCD-O2.
[0100] When no breakage occurs in any of the layers below the breakage detection wiring HCD, the signal is transmitted to the second output pad PD-O2. If a breakage occurs in any of the layers below the breakage detection wiring HCD, for example, in at least one of the left side of the input detection component TU and the via region PA in which the second input trace wiring HCD-I2 and the second output trace wiring HCD-O2 are arranged, the signal may not be transmitted to the second output pad PD-O2.
[0101] According to the present invention, the breakage detection wiring HCD disposed on the same layer as the input detection component TU can determine whether any layer included in the display module DM breaks during the formation of the module hole HM defined by the display module DM. Therefore, an electronic device EA with improved reliability can be provided.

[0106] Although not shown in the accompanying drawings, the display component DU according to one embodiment may further include a buffer layer (not shown). The buffer layer may be disposed on the barrier layer BI. The buffer layer may comprise an inorganic or organic material. The buffer layer may have a higher adhesion force than the barrier layer BI relative to the semiconductor pattern SL or the first insulating layer IL1 of the transistor TR, which will be described later. Therefore, the transistor TR can be stably formed on the substrate BS.

The semiconductor pattern SL may include at least one of crystalline semiconductor material, metal oxide semiconductor material, polycrystalline silicon, and amorphous silicon. Although a control electrode CE disposed on the semiconductor pattern SL is shown in a transistor TR according to one embodiment, the inventive concept is not limited thereto. The control electrode CE may be disposed on the substrate BS and may be covered by a first insulating layer IL1, and may have a bottom gate structure in which the semiconductor pattern SL is disposed on the first insulating layer IL1, but the inventive concept of this disclosure is not limited to any particular embodiment.

However, the inventive concept is not limited thereto, and the second electrode E2 may extend to the hole region PA to cover the hole region PA.
[0117] For example, the second electrode E2 of each of the plurality of organic light-emitting elements (OLEDs) can be configured as a single, interconnected shape. Therefore, the same voltage can be supplied to each of the plurality of OLEDs via the common second electrode E2. Thus, a separate patterning process can be omitted to form the second electrode E2.

For example, the second electrode E2 may include at least one of indium zinc oxide (IZO), indium tin oxide (ITO), indium gallium oxide (IGO), indium gallium zinc oxide (IGZO), and any mixture / compound thereof. Thus, the display module DM displays the image IM on the front surface IS.

[0127] The first sealing inorganic film LIL and the second sealing inorganic film UIL may have an integral shape disposed on the front surface of the display component DU in a planar plane. Each of the first sealing inorganic film LIL and the second sealing inorganic film UIL may partially overlap with the sealing organic film OEL. Therefore, in some areas, the first sealing inorganic film LIL and the second sealing inorganic film UIL may be spaced apart from each other in the third direction D3, while the sealing organic film OEL is located between the first sealing inorganic film LIL and the second sealing inorganic film UIL, and in other areas, the first sealing inorganic film LIL and the second sealing inorganic film UIL may be in direct contact in the third direction D3.

Figure 4B The dam portion DMP shown is formed from multiple layers including a first dam portion DMP1 and a second dam portion DMP2, but the inventive concept of this disclosure is not limited thereto. In some embodiments, the dam portion DMP may have a single-layer structure comprising at least one of the third insulating layer IH and the pixel defining layer PLE.
[0130] The dam section DMP can define the area in which liquid organic material diffuses during the process of forming the sealing organic membrane OEL. The sealing organic membrane OEL can be formed by an inkjet method in which liquid organic material is applied to a first sealing inorganic membrane LIL. In this case, the dam section DMP sets the boundary of the area in which the organic liquid material is applied and prevents the liquid organic material from overflowing outside the dam section DMP.
[0131] According to one embodiment, the display module DM includes a flat portion YP. The flat portion YP includes a flat organic film YOC and a flat inorganic film YIL.
[0132] A flat portion YP is disposed between the display component DU and the input detection component TU. A flat organic film YOC covers a portion of the display component DU. For example, the flat organic film YOC may be disposed on the display component DU that overlaps with the hole region PA. The flat organic film YOC is disposed between the display component DU overlapping the hole region PA and the input detection component TU to compensate for the step between the display component DU and the input detection component TU.
[0133] According to one embodiment, a step CD can be formed at the boundary between the active region AA and the aperture region PA. During the process of applying the planar organic film YOC onto the display component DU, the step CD may be formed due to one or more process errors. The step CD can be formed from the end of the planar organic film YOC adjacent to the sealing portion TFE.
[0134] The flat inorganic film YIL can cover the flat organic film YOC. The flat inorganic film YIL can have an integral shape that overlaps with the front surface of the display component DU.
[0135] The input detection component TU includes a first conductive pattern TML1, a second conductive pattern TML2, a first detection insulating layer TIL1, and a second detection insulating layer TIL2. According to one embodiment, the input detection component TU is disposed on a planar inorganic film YIL. For example, the first conductive pattern TML1 of the first conductive pattern TML1 and the second conductive pattern TML2 can be directly disposed on the planar inorganic film YIL.
[0136] The first detection insulating layer TIL1 is disposed on the flat inorganic film YIL to cover the first conductive pattern TML1.
[0137] The second conductive pattern TML2 in conductive patterns TML1 and TML2 can be directly disposed on the first detection insulating layer TIL1. The second conductive pattern TML2 can also be disposed on a different layer than the first conductive pattern TML1 via the first detection insulating layer TIL1. A portion of the second conductive pattern TML2 can be connected to the first conductive pattern TML1 via the first detection insulating layer TIL1.
[0138] The second detection insulating layer TIL2 is disposed on the first detection insulating layer TIL1 to cover the second conductive pattern TML2.
[0139] According to one embodiment, the first conductive pattern TML1 can be made from... Figure 4A The first connection pattern BP1 shown is formed. The second conductive pattern TML2 can be formed by... Figure 4A The first detection sensor SP1, the second detection sensor SP2, and the second connection pattern BP2 shown in the figure are formed.
[0140] However, the inventive concept of this disclosure is not limited thereto. Depending on the arrangement of the first detection electrode TE1 and the second detection electrode TE2 included in the input detection component TU, based on the first detection insulating layer TIL1, the pattern disposed below the first detection insulating layer TIL1 can be formed by the first conductive pattern TML1, and the pattern disposed on the first detection insulating layer TIL1 can be formed by the second conductive pattern TML2.
[0141] Each of the first conductive pattern TML1 and the second conductive pattern TML2 may not overlap with the light-emitting region PXA of the pixel PX. Therefore, the light provided by the display component DU can be seen by the user without interference from the input detection component TU.
[0142] According to one embodiment, the display component DU may include a first groove BR1 and a second groove BR2. The first groove BR1 and the second groove BR2 overlap with the hole region PA. A portion of an insulating layer including a barrier layer BI, a first insulating layer IL1 and a second insulating layer IL2, and a substrate BS are pressed from the upper surface of the charge control layer OL, and the exposed and recessed surfaces are covered by at least one of a first sealing inorganic film LIL and a second sealing inorganic film UIL, thereby forming the first groove BR1 and the second groove BR2.
[0143] For example, the first groove BR1 can be configured to be separate from the module hole HM, while the dam portion DMP is located between the first groove BR1 and the module hole HM. The first groove BR1 includes a first internal space BR-I1. A portion of the insulating layer, including the barrier layer BI, the first insulating layer IL1, and the second insulating layer IL2, and the substrate BS are pressed from the upper surface of the charge control layer OL, and the exposed and recessed surfaces are covered by a first sealing inorganic film LIL, thereby forming the first internal space BR-I1. The first internal space BR-I1 of the first groove BR1 can be filled with the sealing organic film OEL of the sealing portion TFE.
[0144] The second groove BR2 can be disposed between the dam portion DMP and the module hole HM. The second groove BR2 includes a second internal space BR-I2. A portion of the insulating layer including the barrier layer BI, the first insulating layer IL1 and the second insulating layer IL2, and the substrate BS are pressed from the upper surface of the charge control layer OL, and the exposed and recessed surfaces are covered by the first sealing inorganic film LIL and the second sealing inorganic film UIL, thereby forming the second internal space BR-I2. The second internal space BR-I2 of the second groove BR2 can be filled with a flat organic film YOC of the flat portion YP.
[0145] According to one embodiment, a first groove BR1 and a second groove BR2 arranged around the module aperture HM can block the movement path of moisture and oxygen that may be introduced from the module aperture HM. Therefore, a display module DM with improved reliability can be provided. Furthermore, by filling the internal space BR-I1 of the first groove BR1 and the internal space BR-I2 of the second groove BR2 with organic films such as a sealing organic film OEL and a planar organic film YOC, the first groove BR1 and the second groove BR2 can be provided with improved durability.
[0146] The module aperture HM can be defined by the inner surface GE of the end of the penetrating configuration in the configuration including the display module DM. For example, the penetrating and exposed ends including the end BS-E of the substrate BS, the end BI-E of the barrier layer BI, the end IL1-E of the first insulating layer IL1, the end IL2-E of the second insulating layer IL2, the end OL-E of the charge control layer OL, the end LIL-E of the first sealing inorganic film LIL, the end UIL-E of the second sealing inorganic film UIL, the end YOC-E of the planar organic film YOC, the end YIL-E of the planar inorganic film YIL, the end TIL1-E of the first detection insulating layer TIL1, and the end TIL2-E of the second detection insulating layer TIL2 can define the inner surface GE of the module aperture HM.
[0147] According to the inventive concept of this disclosure, a portion of the crack detection wiring HCD can be disposed on the same layer as at least one of the first conductive pattern TML1 and the second conductive pattern TML2. Figure 4B An embodiment is shown in which a portion of the break detection wiring HCD, cut along line I-I', is disposed on the same layer as the second conductive pattern TML2.
[0148] According to one embodiment, due to the stepped CD formed by the flat organic film YOC, a portion of the crack detection wiring HCD can be further separated from the substrate BS than the second conductive pattern TML2.
[0149] The crack detection wiring HCD can be disposed in a region that overlaps with at least one of the first groove BR1 and the second groove BR2. According to an embodiment, the crack detection wiring HCD can be disposed in the region where the thickness of the flat organic film YOC in the orifice region PA is greatest in the third direction D3. For example, the crack detection wiring HCD can overlap with the groove region GA corresponding to the region in which the second groove BR2 is disposed.
[0150] refer to Figure 5A and Figure 5BThe crack detection wiring HCD includes a first input trace wiring HCD-I1, a second input trace wiring HCD-I2, a first output trace wiring HCD-O1, a second output trace wiring HCD-O2, a hole wiring HCD-C, a first detection wiring HCD-R, and a second detection wiring HCD-L.
[0151] The via wiring HCD-C overlaps with the via region PA. For example, the via wiring HCD-C may overlap with the groove region GA of the second groove BR2 in which the via region PA is disposed. The via wiring HCD-C may have an opening curve that surrounds at least a portion of the module via HM in a plane. The via wiring HCD-C may be spaced apart from the detection electrodes TE1 and TE2 of the input detection component TU. Thus, the via wiring HCD-C may be configured to be spaced apart from the conductive patterns TML1 and TML2.
[0152] According to one embodiment, one end of the via wiring HCD-C is connected to a first detection wiring HCD-R, and the other end, spaced apart from that end of the via wiring HCD-C, is connected to a second detection wiring HCD-L.
[0153] The first detection wiring HCD-R and the second detection wiring HCD-L are spaced apart from each other in a plane by a separating space EG. Each of the first detection wiring HCD-R and the second detection wiring HCD-L extends from the via region PA through the active region AA to the peripheral region NAA.
[0154] For example, one end of the first detection wiring HCD-R is connected to one end of the hole wiring HCD-C disposed in the hole region PA, and the other end of the first detection wiring HCD-R is connected through the active region AA to the first input trace wiring HCD-I1 and the second input trace wiring HCD-I2 disposed in the peripheral region NAA.
[0155] One end of the second detection wiring HCD-L is connected to the other end of the hole wiring HCD-C located in the hole region PA, and the other end of the second detection wiring HCD-L is connected to the first output trace wiring HCD-O1 and the second output trace wiring HCD-O2 located in the peripheral region NAA through the active region AA.
[0156] A portion of each of the first detection wiring HCD-R and the second detection wiring HCD-L may overlap with the boundary between the active region AA and the via region PA.
[0157] According to one embodiment, the first detection wiring HCD-R can be disposed on a different layer than the second detection wiring HCD-L and the via wiring HCD-C. The first detection wiring HCD-R can be disposed separately from the second detection wiring HCD-L and the via wiring HCD-C, and a first detection insulating layer TIL1 is interposed between the first detection wiring HCD-R and the second detection wiring HCD-L and the via wiring HCD-C. The first detection wiring HCD-R and the via wiring HCD-C can be connected via a first contact hole CNT1 penetrating the first detection insulating layer TIL1.
[0158] The first detection wiring HCD-R can be disposed on a different layer than the first input trace wiring HCD-I1 and the second input trace wiring HCD-I2 through the first detection insulating layer TIL1. The first detection wiring HCD-R and the input trace wirings HCD-I1 and HCD-I2 can be connected via the second contact hole CNT2 that penetrates the first detection insulating layer TIL1.
[0159] According to one embodiment, the second detection wiring HCD-L can be disposed on the same layer as the via wiring HCD-C. The second detection wiring HCD-L and the via wiring HCD-C can be disposed on the first detection insulating layer TIL1. Therefore, the second detection wiring HCD-L can be directly connected to the via wiring HCD-C.
[0160] The second detection wiring HCD-L can be disposed on the same layer as the first output trace wiring HCD-O1 and the second output trace wiring HCD-O2. Therefore, the second detection wiring HCD-L can be directly connected to the first output trace wiring HCD-O1 and the second output trace wiring HCD-O2.
[0161] If the first detection wiring HCD-R and the second detection wiring HCD-L are located on the same layer, mutual electrical interference may degrade the reliability of fault detection. For example, when both the first detection wiring HCD-R and the second detection wiring HCD-L are located on the first detection insulating layer TIL1, they are connected to each other, allowing signals to be transmitted to the via wiring HCD-C to be transmitted directly from the first detection wiring HCD-R through the second detection wiring HCD-L without passing through the via wiring HCD-C. As a result, the reliability of the display module DM may be degraded in determining if a fault has occurred in the layer of the display module DM.
[0162] The first detection wiring HCD-R and the second detection wiring HCD-L can be formed using a conductive material through a photolithography process. If the first detection wiring HCD-R and the second detection wiring HCD-L are formed on the same layer, then due to the step CD at the boundary between the active region AA and the via region PA, a residual film is formed in the region where the conductive material is to be fully patterned, making it possible for the first detection wiring HCD-R and the second detection wiring HCD-L to be connected.
[0163] According to the present invention, the first detection wiring HCD-R and the second detection wiring HCD-L, connected to one end of the module hole HM, are spaced apart from each other in a plane by a separating space EG and disposed on different layers, while the first detection insulating layer TIL1 is located between the first detection wiring HCD-R and the second detection wiring HCD-L, so that the mutual interference between the active region AA and the hole region PA can be minimized. Therefore, the reliability of the display module DM used to determine the occurrence of cracks in the layers of the display module DM can be improved.

[0165] The display module DM according to the embodiment (see also) Figure 4B It may include a first dummy pattern DM1 and a second dummy pattern DM2. The first dummy pattern DM1 and the second dummy pattern DM2 are configured to be separate from the break detection wiring HCD.
[0166] The first dummy pattern DM1 can be disposed on a plane in the partition space EG formed between the first detection wiring HCD-R and the second detection wiring HCD-L. The first dummy pattern DM1 is configured to be separate from the first detection wiring HCD-R and the second detection wiring HCD-L.
[0167] The first dummy pattern DM1 can be disposed on the same layer as the second detection wiring HCD-L and the first detection sensor SP1. The first dummy pattern DM1 can have the same grid shape as the first detection sensor SP1.
[0168] According to the present invention, since the first dummy pattern DM1 includes the same layer and the same shape as the first detection sensor SP1 disposed at the uppermost input detection member TU in the input detection member TU, the defect that the space between the first detection sensors SP1 spaced apart from each other can be prevented from being visually identified.
[0169] although Figure 6A A first dummy pattern DM1 is shown disposed between the partition spaces EG, but the inventive concept is not limited thereto, and the first dummy pattern DM1 can be used with the first detection sensor SP1 and the second detection sensor SP2 (see [reference]). Figure 4A The second connection pattern BP2 and the hole area PA are spaced apart and disposed in other areas on the first detection insulating layer TIL1.
[0170] The second dummy pattern DM2 includes a first sub-pattern DM2-1 and a second sub-pattern DM2-2. The second dummy pattern DM2 is disposed on the same layer as the first detection wiring HCD-R. The first sub-pattern DM2-1 may not overlap with the first detection wiring HCD-R and the second detection wiring HCD-L, and may be positioned to surround the via region PA, excluding the separation space EG. The second sub-pattern DM2-2 may not overlap with the first detection wiring HCD-R and the second detection wiring HCD-L, and may be disposed within the separation space EG.
[0171] A second dummy pattern DM2 is disposed on the flat inorganic film YIL and covered by the first detection insulating layer TIL1. The second dummy pattern DM2 is configured to surround the hole region PA, thereby blocking moisture and oxygen from flowing into the module hole HM through the module hole HM. Therefore, a display module DM with improved reliability can be provided.

[0174] The via wiring HCD-C1 has a first width L1. At least one of the first detection wiring HCD-R1 and the second detection wiring HCD-L1 has a second width L2. According to one embodiment, the second width L2 may be greater than the first width L1.
[0175] The first detection sensor SP1 has a third width L3. According to one embodiment, the first width L1 of the via wiring HCD-C1 can be greater than or equal to the third width L3.
[0176] According to one embodiment, since the second width L2 of the first detection wiring HCD-R1 and the second detection wiring HCD-L1 is greater than the first width L1 of the via wiring HCD-C1 and the third width L3 of the first detection sensor SP1, the resistance value of the signal input from the first detection wiring HCD-R1 and the second detection wiring HCD-L1 to the via wiring HCD-C1 / the signal output from the via wiring can be reduced.

[0191] The via wiring HCD-CA can have a shape that is symmetrical with respect to the centerline between the first detection wiring HCD-R and the second detection wiring HCD-L. Furthermore, the number of internal wiring DCs is not limited to one, as long as the internal wiring DCs have an overall shape with an opening curve.
[0192] According to one embodiment, by increasing the area of the via wiring HCD-CA disposed in the via region PA, the display module DM disposed in the region adjacent to the module via HM can be easily determined (see [reference]). Figure 4A The occurrence of fractures in the layers.
