[0032] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0033] FIG. 1 is a perspective view of an electronic device according to one embodiment of the present invention, and FIG. 2 is an exploded perspective view of a display device shown in FIG. 1.

[0034] Referring to FIGS. 1 and FIGS. 2, the electronic device (ED) includes a display device (DD) and an input device (AP).

[0035] The display device (DD) may be a device that is activated according to an electrical signal. The display device (DD) according to the present invention may be a large display device such as a television or monitor, as well as a medium-sized display device such as a mobile phone, tablet, car navigation system, or game console. These are merely examples presented, and it is understood that they may be adopted in other electronic devices as long as they do not deviate from the concept of the present invention. Although a display device (DD) having the shape of a tablet is illustrated in FIG. 1, the present invention is not limited thereto.

[0036] The display device (DD) has a rectangular shape having a long side in the first direction (DR1) and a short side in the second direction (DR2) intersecting the first direction (DR1). However, the shape of the display device (DD) is not limited thereto, and a display device (DD) of various shapes may be provided. The display device (DD) can display an image (IM) toward the third direction (DR3) on a display surface (IS) parallel to each of the first direction (DR1) and the second direction (DR2). The display surface (IS) on which the image (IM) is displayed may correspond to the front surface of the display device (DD). The image (IM) may include a still image as well as a dynamic image.

[0037] In this embodiment, the front (or top) and back (or bottom) surfaces of each member are defined based on the direction in which the image (IM) is displayed. The front and back surfaces are opposed to each other in a third direction (DR3), and the normal direction of each of the front and back surfaces may be parallel to the third direction (DR3).

[0038] The distance between the front and back surfaces in the third direction (DR3) may correspond to the thickness of the display device (DD) in the third direction (DR3). Meanwhile, the directions indicated by the first to third directions (DR1, DR2, DR3) can be converted to other directions as relative concepts.

[0039] The display device (DD) can detect external inputs applied from the outside. External inputs may include various forms of inputs provided from outside the display device (DD). A display device (DD) according to one embodiment of the present invention can detect a first input (TC1) of a user (US) applied from the outside. The first input (TC1) of the user (US) may be any one of various forms of external inputs, such as a part of the user's body, light, heat, or pressure, or a combination thereof. In this embodiment, the first input (TC1) of the user (US) is described as a touch input by the user's (US) hand applied to the front, but this is exemplary, and as described above, the first input (TC1) of the user (US) may be provided in various forms. Additionally, the display device (DD) may detect the first input (TC1) of the user (US) applied to the side or back of the display device (DD) depending on the structure of the display device (DD), and is not limited to any one embodiment.

[0040] Additionally, a display device (DD) according to one embodiment of the present invention can detect a second input (TC2) applied from the outside. The second input (TC2) may include inputs by an input device (AP) included in an electronic device (ED) (e.g., a stylus pen, an active pen, a touch pen, an electronic pen, an e-pen, etc.), in addition to the hand of the user (US). In the following description, the second input (TC2) is described using the case where it is an input by an active pen as an example.

[0041] The display device (DD) and the input device (AP) may be capable of bidirectional communication. The display device (DD) may provide an uplink signal (ULS, see FIG. 4) to the input device (AP). For example, the uplink signal (ULS) may include a synchronization signal or information of the display device (DD), but is not specifically limited thereto. The input device (AP) may provide a downlink signal (DLS, see FIG. 4) to the display device (DD). The downlink signal (DLS) may include a synchronization signal or status information of the input device (AP). For example, the downlink signal (DLS) may include location information of the input device (AP), battery information of the input device (AP), tilt information of the input device (AP), and / or various information stored in the input device (AP), but is not specifically limited thereto. The uplink signal (ULS) and the downlink signal (DLS) will be described later in the description of FIG. 4. The front surface of the display device (DD) can be divided into a transparent area (TA) and a bezel area (BZA). The transparent area (TA) may be an area where an image (IM) is displayed. The user perceives the image (IM) through the transparent area (TA). In this embodiment, the transparent area (TA) is depicted as a square shape with rounded vertices. However, this is illustrated as an example, and the transparent area (TA) may have various shapes and is not limited to any one embodiment.

[0042] The bezel area (BZA) is adjacent to the transparent area (TA). The bezel area (BZA) may have a predetermined color. The bezel area (BZA) may surround the transparent area (TA). Accordingly, the shape of the transparent area (TA) may be substantially defined by the bezel area (BZA). However, this is illustrated as an example, and the bezel area (BZA) may be positioned adjacent to only one side of the transparent area (TA) or may be omitted. A display device (DD) according to one embodiment of the present invention may include various embodiments and is not limited to any one embodiment.

[0043] As illustrated in FIG. 2, the display device (DD) may include a display module (DM) and a window (WM) placed on the display module (DM). The display module (DM) may include a display panel (DP) and an input sensing layer (ISP).

[0044] A display panel (DP) according to one embodiment of the present invention may be a light-emitting display panel, but is not particularly 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. The light-emitting layer of the quantum dot light-emitting display panel may include quantum dots and quantum rods, etc. Hereinafter, the display panel (DP) is described as an organic light-emitting display panel. The display panel (DP) outputs an image (IM), and the output image may be displayed through a display surface (IS).

[0045] The input detection layer (ISP) is placed on the display panel (DP) and can detect the first input (TC1) and the second input (TC2). The configuration and operation of the input detection layer (ISP) will be described later with reference to FIGS. 3 to 5.

[0046] The window (WM) may be made of a transparent material capable of emitting an image (IM). For example, it may be composed of glass, sapphire, plastic, etc. The window (WM) is depicted as a single layer, but is not limited thereto and may include multiple layers.

[0047] Meanwhile, although not illustrated, the bezel area (BZA) of the display device (DD) described above may substantially be provided as an area in which a material containing a predetermined color is printed on a part of the window (WM). In one example of the present invention, the window (WM) may include a light-blocking pattern for defining the bezel area (BZA). The light-blocking pattern may be formed as a colored organic film, for example, by a coating method.

[0048] A window (WM) can be coupled to a display module (DM) via an adhesive film. As an example of the present invention, the adhesive film may include an optically clear adhesive film (OCA). However, the adhesive film is not limited thereto and may include a conventional adhesive or pressure-sensitive adhesive. For example, the adhesive film may include an optically clear resin (OCR) or a pressure-sensitive adhesive film (PSA).

[0049] An anti-reflective layer may be further disposed between the window (WM) and the display module (DM). The anti-reflective layer reduces the reflectance of external light incident from the upper side of the window (WM). An anti-reflective layer according to one embodiment of the present invention may include a phase retarder and a polarizer. The phase retarder may be of the film type or liquid crystal coating type and may include a λ / 2 phase retarder and / or a λ / 4 phase retarder. The polarizer may also be of the film type or liquid crystal coating type. The film type may include a stretched synthetic resin film, and the liquid crystal coating type may include liquid crystals arranged in a predetermined array. The phase retarder and the polarizer may be implemented as a single polarizing film.

[0050] The display module (DM) can display an image according to an electrical signal and transmit / receive information regarding an external input. The display module (DM) can be defined as an effective area (AA) and an ineffective area (NAA). The effective area (AA) can be defined as an area that emits an image provided by the display module (DM). Additionally, the effective area (AA) can be defined as an area where the input sensing layer (ISP) detects a first input (TC1) and a second input (TC2) applied from the outside.

[0051] The non-effective area (NAA) is adjacent to the effective area (AA). For example, the non-effective area (NAA) may surround the effective area (AA).

According to one embodiment, the effective area (AA) of the display module (DM) may correspond to at least a portion of the transparent area (TA).

[0052] The display module (DM) may further include a first main circuit board (MCB1), a first flexible circuit film (D-FCB), and a first driving chip (DIC). The first main circuit board (MCB1) may be connected to the first flexible circuit film (D-FCB) and electrically connected to the display panel (DP). The first flexible circuit film (D-FCB) is connected to the display panel (DP) and electrically connects the display panel (DP) and the first main circuit board (MCB1).

[0053] The first main circuit board (MCB1) may include a plurality of driving elements. The plurality of driving elements may include circuit portions for driving a display panel (DP). A first driving chip (DIC) may be mounted on the first flexible circuit film (D-FCB). As an example of the present invention, the first flexible circuit film (D-FCB) may include a first sub-flexible circuit film (D-FCB1), a second sub-flexible circuit film (D-FCB2), and a third sub-flexible circuit film (D-FCB3). The first driving chip (DIC) may include a first sub-driving chip (DIC1), a second sub-driving chip (DIC2), and a third sub-driving chip (DIC3). In this case, the first to third sub-flexible circuit films (D-FCB1 to D-FCB3) are spaced apart from each other at a constant interval and connected to a display panel (DP) to electrically connect the display panel (DP) and the first main circuit board (MCB1). A first sub-driver chip (DIC1) may be mounted on the first sub-flexible circuit film (D-FCB1). A second sub-driver chip (DIC2) may be mounted on the second sub-flexible circuit film (D-FCB2).

Additionally, the display panel (DP) may be electrically connected to the main circuit board (MCB1) through four or more flexible circuit films, and sub-driving chips may be mounted on each of the flexible circuit films. Furthermore, the first driving chip (DIC) may be mounted directly on the display panel (DP).

Additionally, the second main circuit board (MCB2) shown in FIG. 2 may be omitted, and the second flexible circuit film (I-FCB) may be directly connected to the first main circuit board (MCB1).

[0056] The display device (DD) further includes an external case (EDC) that accommodates a display module (DM). The external case (EDC) may be combined with a window (WM) to define the appearance of the display device (DD). The external case (EDC) absorbs shocks applied from the outside and prevents foreign substances / moisture, etc. from penetrating into the display module (DM), thereby protecting the components housed in the external case (EDC).

[0059] Referring to FIG. 3, the display module (DM) includes a display panel (DP) and an input sensing layer (ISP). The display panel (DP) includes a base layer (BL), a circuit element layer (DP-CL) disposed on the base layer (BL), a display element layer (DP-OLED), an encapsulation substrate (EC), and a sealant (SM) that bonds the circuit element layer (DP-CP) and the encapsulation substrate (EC).

In this case, a filler may be filled between the encapsulation substrate (EC) and the display element layer (DP-OLED).

[0065] The input sensing layer (ISP) can be formed on the display panel (DP) by a continuous process. Additionally, the input sensing layer (ISP) and the display panel (DP) can be bonded together through an adhesive film. The input sensing layer (ISP) may have a multilayer structure. The input sensing layer (ISP) may include a single layer or a multilayer insulating layer. According to one embodiment of the present invention, when the input sensing layer (ISP) is placed directly on the display panel (DP) by a continuous process, the input sensing layer (ISP) is placed directly on the encapsulation substrate (EC), and an adhesive film is not placed between the input sensing layer (ISP) and the display panel (DP). However, as another example, an adhesive film may be placed between the input sensing layer (ISP) and the display panel (DP).

[0070] An input sensing layer (ISP) is placed on a display panel (DP) and can detect an input applied from the outside. The input sensing layer (ISP) can detect a first input (TC1, see FIG. 1) by a user (US, see FIG. 1) and a second input (TC2, see FIG. 1) by an input device (AP).

[0071] The main controller (1000) can control the overall operation of the display device (DD). In one example of the present invention, the main controller (1000) can control the operation of the panel controller (2000) and the sensing controller (3000).

[0072] The panel controller (2000) can receive image data (RGB) and a control signal (D-CS) from the main controller (1000). The control signal (D-CS) may include various signals. For example, the control signal (D-CS) may include a vertical synchronization signal, a horizontal synchronization signal, a main clock, and a data enable signal. Based on the control signal (D-CS), the panel controller (2000) can generate a vertical start signal and a horizontal start signal to control the timing of providing signals to the display panel (DP). The sensing controller (3000) can control the input sensing layer (ISP). The sensing controller (3000) can receive a sensing control signal (I-CS) from the main controller (1000). The sensing control signal (I-CS) may include a mode determination signal and a clock signal that determine the driving mode of the sensing controller (3000). The sensing controller (3000) can control the input sensing layer (ISP) based on the sensing control signal (I-CS) to a first mode that detects a first input (TC1) by the body of the user (US) or a second mode that detects a second input (TC2) by the input device (AP). The input sensing layer (ISP) can operate in the first mode or the second mode based on the mode determination signal.

[0073] The sensing controller (3000) can calculate coordinate information of a first input (TC1) or a second input (TC2) based on a signal received from an input sensing layer (ISP), and provide a coordinate signal (I-SS) containing the coordinate information to the main controller (1000). The main controller (1000) executes an operation corresponding to a user input based on the coordinate signal (I-SS). For example, the main controller (1000) can operate the panel controller (2000) to display a new image on the display panel (DP) based on the coordinate signal (I-SS).

[0074] The input device (AP) may include a communication module (100), a pen controller (200), a power supply (300), a housing (400), and a pen electrode (500). However, the components constituting the input device (AP) are not limited to the components listed above. For example, the input device (AP) may further include an electrode switch for switching between a signal transmission mode and a signal reception mode, a pressure sensor for detecting pressure, a memory for storing certain information, or a rotation sensor for detecting rotation.

[0075] The housing (400) may have a pen shape and may have a receiving space formed inside. The receiving space defined inside the housing (400) may accommodate a power source (300), a pen controller (200), a communication module (100), and a pen electrode (500).

[0076] The power supply (300) can supply power to the pen controller (200), communication module (100), etc. inside the input device (AP). The power supply (300) may include a battery or a high-capacity capacitor.

[0077] The pen controller (200) can control the operation of the input device (AP). The pen controller (200) may be an application-specific integrated circuit (ASIC). The pen controller (200) may be configured to operate according to a designed program.

[0078] The communication module (100) may include a transmitting circuit (110) and a receiving circuit (120). The transmitting circuit (110) may output a downlink signal (DLS) to an input sensing layer (ISP). The receiving circuit (120) may receive an uplink signal (ULS) provided by the input sensing layer (ISP). The transmitting circuit (110) may receive a signal provided by the pen controller (200) and modulate it into a signal that can be sensed by the input sensing layer (ISP), and the receiving circuit (120) may modulate the signal provided by the input sensing layer (ISP) into a signal that can be processed by the pen controller (200).

[0079] The pen electrode (500) may be electrically connected to the communication module (100). A portion of the pen electrode (500) may protrude from the housing (400). Alternatively, the input device (AP) may further include a cover housing that covers the pen electrode (500) exposed from the housing (400). Alternatively, the pen electrode (500) may be embedded inside the housing (400).

[0080] FIG. 5 is a cross-sectional view showing the configuration of an input sensing layer and an encapsulation substrate according to one embodiment of the present invention.

[0081] Referring to FIG. 5, an input sensing layer (ISP) according to one embodiment of the present invention may include a first sensing insulating layer (IIL1), a first conductive layer (ICL1), a second sensing insulating layer (IIL2), a second conductive layer (ICL2), and a third sensing insulating layer (IIL3). The first sensing insulating layer (IIL1) may be placed directly on an encapsulation substrate (EC). In one embodiment of the present invention, the first sensing insulating layer (IIL1) may be omitted.

[0082] Each of the first conductive layer (ICL1) and the second conductive layer (ICL2) includes a plurality of conductive patterns. The conductive patterns may include sensing electrodes (SE1-1 to SE1-4 and SE2-1 to SE2-6, see FIG. 6) and signal lines connected thereto (SL1_1a to SL1_4a, SL1_1b to SL1_4b and SL2-1 to SL2_6, see FIG. 6).

[0083] Each of the first sensing insulating layer (IIL1) to the third sensing insulating layer (IIL3) may include an inorganic or organic material. In this embodiment, the first sensing insulating layer (IIL1) and the second sensing insulating layer (IIL2) may be inorganic layers. The inorganic layer may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide. The thickness of the inorganic layer may be 1,000 angstroms to 4,000 angstroms.

[0084] The third sensing insulating layer (IIL3) may be an organic layer. The organic layer may include at least one of an acrylic resin, a methacrylic resin, a polyisoprene, a vinyl resin, an epoxy resin, a urethane resin, a cellulose resin, a siloxane resin, a polyimide resin, a polyamide resin, and a perylene resin. The third sensing insulating layer (IIL3) containing an organic material can prevent moisture, etc. from entering the first conductive layer (ICL1) and the second conductive layer (ICL2) from the outside.

[0085] FIG. 6 is a plan view showing the configuration of an input sensing layer according to an embodiment of the present invention. FIG. 7a is an enlarged plan view showing a portion of the input sensing layer corresponding to AA' in FIG. 6, and FIG. 7b is an enlarged plan view showing a portion of the input sensing layer corresponding to BB' in FIG. 6.

[0086] Referring to FIG. 6, an input sensing layer (ISP) according to one embodiment of the present invention may include a plurality of sensing electrodes (SE1_1 to SE1_4, SE2_1 to SE2_6) disposed in an effective area (AA) and a plurality of signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b, SL2_1 to SL2_6) disposed in a non-effective area (NAA) adjacent to the effective area (AA) and electrically connected to the sensing electrodes (SE1_1 to SE1_4, SE2_1 to SE2_6).

[0087] In one example of the present invention, the sensing electrodes (SE1_1 to SE1_4, SE2_1 to SE2_6) include transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6).

[0088] The signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b and SL2-1 to SL2_6) may include transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) connected to the transmission electrodes (SE1_1 to SE1_4). In one example of the present invention, the transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) may include first transmission signal lines (SL1_1a to SL1_4a) respectively connected to a first end of the transmission electrodes (SE1_1 to SE1_4) and second transmission signal lines (SL1_1b to SL1_4b) respectively connected to a second end of the transmission electrodes (SE1_1 to SE1_4). At this time, the first terminal of the transmitting electrodes (SE1_1 to SE1_4) refers to a terminal located relatively closer to the input pads (I-PD) to be described later than the second terminal of the transmitting electrodes (SE1_1 to SE1_4), and the second terminal of the transmitting electrodes (SE1_1 to SE1_4) may refer to a terminal located relatively farther from the input pads (I-PD) than the first terminal of the transmitting electrodes (SE1_1 to SE1_4).

[0089] Additionally, the signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b and SL2_1 to SL2_6) may include receiving signal lines (SL2_1 to SL2_6) each connected to a first terminal of the receiving electrodes (SE2_1 to SE2_6). In one example of the present invention, the input sensing layer (ISP) may further include receiving signal lines each connected to a second terminal of the receiving electrodes (SE2_1 to SE2_6).

[0090] The transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6) intersect each other. The transmitting electrodes (SE1_1 to SE1_4) are arranged in a second direction (DR2), and each extends in a first direction (DR1). The receiving electrodes (SE2_1 to SE2_6) are arranged in a first direction (DR1), and each extends in a second direction (DR2).

[0091] The above-described input sensing layer (ISP) can acquire coordinate information using a mutual-cap method. Capacitance is formed between the transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6). The capacitance between the transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6) can be changed by a first input (TC1, see FIG. 1) or a second input (TC2, see FIG. 1). Here, the sensing sensitivity of the input sensing layer (ISP) can be determined according to the amount of change in capacitance. That is, the greater the amount of change in capacitance caused by the first input (TC1) or the second input (TC2), the more the sensing sensitivity of the input sensing layer (ISP) is improved.

[0092] Each of the transmitting electrodes (SE1_1 to SE1_4) includes a first sensor unit (SP1) and a first connection unit (CP1) disposed in an effective area (AA). Each of the receiving electrodes (SE2_1 to SE2_6) includes a second sensor unit (SP2) and a second connection unit (CP2) disposed in an effective area (AA).

[0093] FIG. 6 illustrates transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6) according to one embodiment, but their shapes are not limited thereto. In one embodiment of the present invention, the transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6) may have a shape in which there is no distinction between the sensor part and the connection part (e.g., a bar shape). Although the first sensor part (SP1) and the second sensor part (SP2) are illustrated as illustrative examples of rhombus shapes, they are not limited thereto, and the first sensor part (SP1) and the second sensor part (SP2) may have different polygonal shapes.

[0094] Within one transmitting electrode, the first sensor units (SP1) are arranged along the first direction (DR1), and within one receiving electrode, the second sensor units (SP2) are arranged along the second direction (DR2). Each of the first connecting units (CP1) connects adjacent first sensor units (SP1), and each of the second connecting units (CP2) connects adjacent second sensor units (SP2).

[0095] Each of the transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6) may have a mesh shape. By each of the transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6) having a mesh shape, the parasitic capacitance with the electrodes of the display panel (DP, see FIG. 2) may be reduced.

[0096] The mesh-shaped transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6) may include silver, aluminum, copper, chromium, nickel, titanium, etc., but are not limited thereto.

[0097] The first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and reception signal lines (SL2_1 to SL2_6) may be placed in a non-effective area (NAA).

[0098] The input sensing layer (ISP) may include input pads (I-PD) that extend from one end of the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) and are disposed in an inactive area (NAA). The input pads (I-PD) may be electrically connected to the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6). In one example of the present invention, input pads (I-PD) include a first transmission input pad (T-PD1) to which first transmission signal lines (SL1_1a to SL1_4a) are electrically connected, and a second transmission input pad (T-PD2) to which second transmission signal lines (SL1_1b to SL1_4b) are electrically connected. Input pads (I-PD) may further include a reception input pad (R-PD) to which reception signal lines (SL2_1 to SL2_6) are electrically connected.

[0099] In one example of the present invention, the non-effective area (NAA) may include a first area (NAA1), a second area (NAA2), a third area (NAA3), and a pad area (PLD) in which input pads (I-PD) are arranged.

[0100] The first region (NAA1) may be a region adjacent to the effective region (AA). The second region (NAA2) may be a region adjacent to the pad region (PLD). The third region (NAA3) may be a region adjacent to the first region (NAA1) and the second region (NAA2). In one example of the present invention, the third region (NAA3) may be positioned between the first region (NAA1) and the second region (NAA2).

[0101] As an example of the present invention, each of the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and reception signal lines (SL2_1 to SL2_6) may include first sub-lines (SSL1), second sub-lines (SSL2), and third sub-lines (SSL3).

[0102] Specifically, the first sub-lines (SSL1) may be a portion electrically connected to the transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6) among the first and second transmitting signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and receiving signal lines (SL2_1 to SL2_6). The first sub-lines (SSL1) may be a portion disposed in the first region (NAA1) among the first and second transmitting signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and receiving signal lines (SL2_1 to SL2_6). Each of the first sub-lines (SSL1) may include a portion directly coupled to a corresponding electrode among the transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6).

[0103] The second sub-lines (SSL2) may be a portion electrically connected to the input pads (I-PD) among the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6). The second sub-lines (SSL2) may be a portion disposed in the second region (NAA2) among the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6). Each of the second sub-lines (SSL2) may include a portion directly coupled to a corresponding input pad among the input pads (I-PD).

[0104] The third sub-lines (SSL3) may be a portion that electrically connects the first sub-lines (SSL1) and the second sub-lines (SSL2). The third sub-lines (SSL3) may be a portion disposed in the third region (NAA3) among the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and reception signal lines (SL2_1 to SL2_6). One end of each of the third sub-lines (SSL3) is electrically connected to the corresponding first sub-line, and the other end is electrically connected to the corresponding second sub-line. Each of the third sub-lines (SSL3) may have an integral shape with the corresponding first sub-line and the corresponding second sub-line.

[0105] Referring to FIGS. 6 to 7B, the spacing between first sub-lines (SSL1) arranged within a first region (NAA1) can be referred to as a first spacing (w1). In this case, the first spacing (w1) may include a first sub-spacing (w1_a) and a second sub-spacing (w1_b). The first sub-spacing (w1_a) is defined as the spacing in the second direction (DR2) between the parts of the first sub-lines (SSL1) that extend in the first direction (DR1). The second sub-spacing (w1_b) is defined as the spacing in the first direction (DR1) between the parts of the first sub-lines (SSL1) that extend in the second direction (DR2). The second sub-spacing (w1_b) may be smaller than the first sub-spacing (w1_a).

[0106] Additionally, the spacing between the second sub-lines (SSL2) placed within the second region (NAA2) can be referred to as the second spacing (w2). The spacing between the third sub-lines (SSL3) placed within the third region (NAA3) can be referred to as the third spacing (w3). In one example of the present invention, the third spacing (w3) may be smaller than the first and second spacings (w1, w2). In one example of the present invention, the third spacing (w3) may be smaller than the second sub-spacing (w1_b) and the second spacing (w2).

[0107] Specifically, when input pads (I-PDs) are arranged in a first direction (DR1), second sub-lines (SSL2), which are electrically connected to the input pads (I-PDs), extend in a direction intersecting the first direction (DR1) within the second region (NAA2). In one example of the present invention, the second sub-lines (SSL2) may extend in a second direction (DR2) orthogonal to the first direction (DR1). However, the present invention is not limited thereto. That is, the second sub-lines (SSL2) may extend in a direction inclined with respect to the first direction (DR1) and the second direction (DR2).

[0108] Third sub-lines (SSL3) electrically connected to each of the second sub-lines (SSL2) may be arranged within the third area (NAA3) to have a third gap (w3) smaller than the second gap (w2). Each of the third sub-lines (SSL3) may be arranged to include a stepped shape. Each of the third sub-lines (SSL3) may include a portion extending in the first direction (DR1) (hereinafter, a horizontal portion) and a portion extending in the second direction (DR2) (hereinafter, a vertical portion). By each of the third sub-lines (SSL3) including a horizontal portion, the gap between each of the third sub-lines (SSL3) may be arranged to be small. The third gap (w3) may include a third sub-gap (w3_a) and a fourth sub-gap (w3_b). The third sub-spacing (w3_a) is defined as the spacing in the second direction (DR2) between the portions of the third sub-lines (SSL3) that extend in the first direction (DR1). The fourth sub-spacing (w3_b) is defined as the spacing in the first direction (DR1) between the portions of the third sub-lines (SSL3) that extend in the second direction (DR2). The third sub-spacing (w3_a) and the fourth sub-spacing (w3_b) may be smaller than the first spacing (w1) and the second spacing (w2). As an example of the present invention, the lengths of the horizontal portions of each third sub-line (SSL3) may be arranged differently so that the third sub-spacing (w3_a) and the fourth sub-spacing (w3_b) are smaller than the first spacing (w1) and the second spacing (w2).

[0109] Each of the third sub-lines (SSL3) may be arranged within the third region (NAA3) such that the third spacing (w3) is maintained, by including a shape in which a portion extending in the first direction (DR1) and a portion extending in the second direction (DR2) are repeated. In one example of the present invention, the third sub-lines (SSL3) may be arranged such that the third sub-spacing (w3_a) and the fourth sub-spacing (w3_b) are maintained constant.

[0110] Additionally, as an example of the present invention, each of the third sub-lines (SSL3) may include a shape extending in a fourth direction (DR4) or a fifth direction (DR5) that intersects the first direction (DR1). Each of the third sub-lines (SSL3) may include a shape extending in the fourth direction (DR4) or the fifth direction (DR5) so that the spacing between adjacent third sub-lines (SSL3) is small.

[0111] The first sub-lines (SSL1) electrically connected to the third sub-lines (SSL3) are arranged to have a first interval (w1) within the first area (NAA1) and can be electrically connected to the transmitting electrodes (SE1_1 to SE1_4) and the receiving electrodes (SE2_1 to SE2_6). In one example of the present invention, the first interval (w1) may be larger than the third interval (w3). However, the present invention is not limited thereto, and among the first intervals (w1), the first sub-interval (w1_a) may be larger than the third interval (w3), and the second sub-interval (w1_b) may be equal to or larger than the third interval (w3).

[0112] The input sensing layer (ISP) calculates coordinate information of the first input (TC1, see FIG. 1) or the second input (TC2, see FIG. 1) based on the first input (TC1) or the second input (TC2) provided in the effective area (AA) where the transmitting electrodes (SE1_1 to SE1_4) and receiving electrodes (SE2_1 to SE2_6) are arranged.

[0113] When the input sensing layer (ISP) performs the operation of sensing the second input (TC2), if the gap between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) placed in the third area (NAA3) of the non-effective area (NAA) is large, the change in parasitic capacitance between adjacent lines caused by the second input (TC2) provided in the third area (NAA3) is detected by the input sensing layer (ISP). In the case of the third region (NAA3), the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and reception signal lines (SL2_1 to SL2_6) are densely arranged in a narrower area compared to the first region (NAA1), so that a change in parasitic capacitance between adjacent lines caused by the second input (TC2) is detected by the input detection layer (ISP). Specifically, if the spacing between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and reception signal lines (SL2_1 to SL2_6) within the dense third region (NAA3) is such that the input signal caused by the second input (TC2) is located between two adjacent lines, then a change in parasitic capacitance caused by the second input (TC2) can be detected by the input detection layer (ISP). In this case, the input sensing layer (ISP) may mistake the second input (TC2) provided in the third area (NAA3) for being provided in the valid area (AA). Consequently, a ghost touch phenomenon occurs in which the input sensing layer (ISP) mistakes the coordinate information of the second input (TC2) for being in the valid area (AA), and the display device (DD, see FIG. 1) and the electronic device (ED, see FIG. 1) may malfunction due to the misidentified coordinate information.

[0114] However, according to the present invention, in a third region (NAA3) excluding a second region (NAA2) adjacent to a pad region (PLD) in a non-effective region (NAA) and a first region (NAA1) adjacent to an effective region (AA), the spacing between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) can be arranged to be small. When the spacing between two adjacent lines is small, the input signal by the second input (TC2) may be positioned overlappingly on multiple lines. In this case, the change in parasitic capacitance between adjacent lines by the second input (TC2) provided in the third region (NAA3) may not be detected by the input sensing layer (ISP). Therefore, the occurrence of the aforementioned ghost touch phenomenon can be prevented, and accordingly, the display device (DD) and the electronic device (ED) can be prevented from malfunctioning.

[0115] The input sensing layer (ISP) may further include ground lines (GNL1, GNL2) to which ground power is applied, which are disposed between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6).

[0116] As an example of the present invention, input pads (I-PD) may further include ground pads (GPD1, GPD2) to which ground lines (GNL1, GNL2) are electrically connected. For connecting the ground lines (GNL1, GNL2) to a ground power source, a ground power source may be applied to the ground pads (GPD1, GPD2).

[0117] Ground lines (GNL1, GNL2) are placed between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) to prevent coupling phenomena occurring between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6), thereby increasing the sensing sensitivity of the input sensing layer (ISP).

[0118] In one example of the present invention, the input sensing layer (ISP) may further include a dummy electrode (DE) disposed between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6). The dummy electrode (DE) may include a plurality of sub-dummy electrodes (SDE).

[0119] As an example of the present invention, the spacing between each first and second transmission signal line (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the spacing between each reception signal line (SL2_1 to SL2_6) disposed on an input sensing layer (ISP) can be arranged in a constant manner to prevent the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) from being visible from the outside. Accordingly, each first transmission signal line (SL1_1a to SL1_4a) can be arranged adjacently, each second transmission signal line (SL1_1b to SL1_4b) can be arranged adjacently, and each reception signal line (SL2_1 to SL2_6) can be arranged adjacently.

[0120] At this time, if the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6) are arranged such that the third gap (w3) is smaller than the first and second gaps (w1, w2) according to the present invention, a gap is created between the first and second transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the reception signal lines (SL2_1 to SL2_6), so that the corresponding part can be seen from the outside.

[0121] Accordingly, by placing a dummy electrode (DE) including a plurality of sub-dummy electrodes (SDE) in the aforementioned separation space, the separation space can be prevented from being visible from the outside.

[0122] Specifically, the sub-dummy electrodes (SDE) are spaced apart from each other, and when the spacing between two adjacent sub-dummy electrodes among the sub-dummy electrodes (SDE) is called the fourth spacing (w4), the fourth spacing (w4) may be equal to the third spacing (w3). In this case, the spacing between the transmission signal lines (SL1_1a to SL1_4a, SL1_1b to SL1_4b) and the spacing between the reception signal lines (SL2_1 to SL2_6) included within the third region (NAA3) are arranged to be repeated in the dummy electrodes (DE), thereby preventing the spacing space from being visible from the outside. However, as an example of the present invention, the sub-dummy electrodes (SDE) may be arranged to include other spacings in addition to the fourth spacing (w4).

[0146] Referring to FIGS. 9 to 11, a display device (DD) having the shape of a mobile phone is illustrated. FIGS. 9 and 10 illustrate that the display device (DD) has a flat structure, but the present invention is not limited thereto. The display device (DD) can be bent or folded with respect to a folding axis and can also have a sliding structure.

[0147] A display module (DM) included in a display device (DD) includes a display panel (DP) and an input sensing layer (ISP). The display module (DM) may further include a main circuit board (MCB), a flexible circuit film (FCB), and a driver chip (DIC). The main circuit board (MCB) may be connected to the flexible circuit film (FCB) and electrically connected to the display panel (DP). The flexible circuit film (FCB) is connected to the display panel (DP) and electrically connects the display panel (DP) and the main circuit board (MCB). The input sensing layer (ISP) may also be electrically connected to the main circuit board (MCB) through the flexible circuit film (FCB). However, embodiments of the present invention are not limited thereto. That is, the display module (DM) may additionally include a separate flexible circuit film for electrically connecting the input sensing layer (ISP) to the main circuit board (MCB).

[0148] The main circuit board (MCB) may include a plurality of driving elements. The plurality of driving elements may include circuit portions for driving a display panel (DP). A driving chip (DIC) may be mounted on a flexible circuit film (FCB). However, embodiments of the present invention are not limited thereto. For example, the driving chip (DIC) may be mounted directly on the display panel (DP). In this case, the portion of the display panel (DP) on which the driving chip (DIC) is mounted may be bent and placed on the rear side of the display module (DM). The driving chip (DIC) may include driving elements for driving pixels of the display panel (DP), for example, a data driving circuit.

[0149] The display module (DM) may further include a controller for controlling the driving of the input sensing layer (ISP). That is, although not shown, the controller may be mounted on the main circuit board (MCB). However, as another example, the controller may be embedded in the driver chip (DIC).

[0150] A display panel (DP) may include a base layer (BL), a circuit element layer (DP-CL) disposed on the base layer (BL), a display element layer (DP-OLED), and an encapsulation layer (TFE).

[0151] The base layer (BL) may include at least one plastic film. The base layer (BL) may be a flexible substrate, such as a plastic substrate, a glass substrate, a metal substrate, or an organic / inorganic composite material substrate. The effective region (AA) and the non-effective region (NAA) described with reference to FIG. 1 may be defined identically in the base layer (BL).

[0152] The display element layer (DP-OLED) is disposed on the circuit element layer (DP-CL) and may include a light-emitting element. The light-emitting element may include at least organic light-emitting diodes.

Additionally, the input sensing layer (ISP) and the display panel (DP) can be bonded together through an adhesive film. The input sensing layer (ISP) may have a multilayer structure. The input sensing layer (ISP) may include a single layer or a multilayer insulating layer. According to one embodiment of the present invention, when the input sensing layer (ISP) is placed directly on the display panel (DP) by a continuous process, the input sensing layer (ISP) is placed directly on the encapsulation layer (TFE), and an adhesive film is not placed between the input sensing layer (ISP) and the display panel (DP). However, as another example, an adhesive film may be placed between the input sensing layer (ISP) and the display panel (DP). In this case, the input sensing layer (ISP) is not manufactured by a continuous process with the display panel (DP), but is manufactured through a separate process from the display panel (DP) and then fixed to the upper surface of the display panel (DP) by an adhesive film.

[0155] FIG. 12 is a plan view showing the configuration of the input sensing layer illustrated in FIG. 10. Hereinafter, the same reference numerals will be assigned to configurations identical to those described in FIG. 6 to FIG. 8c, and redundant descriptions will be omitted.

[0161] Specifically, when input pads (I-PDs) are arranged in a first direction (DR1), second sub-lines (SSL2_a), which are electrically connected to the input pads (I-PDs), are arranged to have a second gap (w2_c) by extending in a second direction (DR2) that intersects the first direction (DR1) within the second area (NAA2).

Each of the third sub-lines (SSL3_a) may be arranged with a small gap between adjacent third sub-lines (SSL3_a) by including a portion extending in the first direction (DR1) or a portion extending in the fourth direction (DR4). Additionally, the third sub-lines (SSL3_a) may be arranged to include both the portion extended in the first direction (DR1) and the portion extended in the fourth direction (DR4), or both the portion extended in the first direction (DR1) and the portion extended in the fifth direction (DR5).

[0163] Additionally, the input pads (I-PDa) may further include pixel pads (D-PD) for connecting a flexible circuit film (FCB, see FIG. 10) to a display panel (DP, see FIG. 10).
