[0040] In this disclosure, it will be understood that when an element or layer is referred to as being “on”, “connected to”, or “linked to” another element or layer, it may be directly on, connected to, or linked to another element or layer, or there may be an intervening element or layer.

[0041] Throughout the specification, the same reference numerals may denote the same elements. In the drawings, for clarity, the thickness, scale, and dimensions of parts may be exaggerated.

[0042] It will be understood that the term “and / or” includes any and all combinations of one or more of the relevant listed items.

[0043] It will be understood that while the terms first, second, etc., may be used herein to describe various elements, components, regions, layers, and / or periods, these elements, components, regions, layers, and / or periods should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or period from another. Therefore, without departing from the scope of the inventive concept, the first element, first component, first region, first layer, or first period discussed below may be referred to as a second element, second component, second region, second layer, or second period. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0044] Furthermore, for ease of description, spatially relative terms such as “below,” “under,” “down,” “above,” and “up” are used herein to describe the relationship between one element or feature and another element(s) as shown in the figures. It will be understood that, in addition to the orientations depicted in the figures, the spatially relative terms are intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “under” other elements or features will be oriented “above” other elements or features. Thus, in the example, the terms “below” and “under” can cover both above and below / under orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein can be interpreted accordingly.

[0045] In the following description, embodiments of the inventive concept will be described more fully with reference to the accompanying drawings.

[0046] Figure 1 This is a perspective view showing a display device DD according to an embodiment of the concept of the present invention.

[0047] Figure 2 This is an exploded perspective view of a display device DD according to an embodiment of the concept of the present invention.

[0048] Figure 3 It is along Figure 2 The line I-I' shown is a cross-sectional view of the display device DD.

[0049] Reference Figures 1 to 3A display device (DD) can be a device activated in response to an electrical signal. A display device (DD) can be included in various electronic devices. For example, a display device (DD) can be used in electronic devices such as smartwatches, tablet computers, laptop computers, computers, smart TVs, etc.

[0050] The display device DD can display an image IM through a display surface IS facing a third direction DR3, wherein the display surface IS is substantially parallel to each of the first direction DR1 and the second direction DR2. The display surface IS through which the image IM is displayed can correspond to the front surface of the display device DD. The image IM can include video and / or still images.

[0051] In this embodiment, the front surface (or, for example, the upper surface) and the rear surface (or, for example, the lower surface) of each component of the display device DD are defined relative to the direction along which its displayed image IM is directed. The front and rear surfaces are opposite to each other on a third direction DR3, and the normal direction of each of the front and rear surfaces may be substantially parallel to the third direction DR3.

[0052] The spacing between the front and rear surfaces on the third direction DR3 can correspond to the thickness of the display device DD on the third direction DR3. Furthermore, the first direction DR1, the second direction DR2, and the third direction DR3 are relative to each other and can be changed to other directions.

[0053] The display device DD can sense external input applied to it from the outside. For example, external input includes various forms of input provided from outside the display device DD. For instance, external input may include proximity input (e.g., hovering) applied when a user's body (e.g., a finger) or device (e.g., a stylus) enters within a predetermined distance of the display device DD. Further examples of external input include touch input via the user's body (e.g., the user's hand). Furthermore, external input may be provided in the form of force, pressure, temperature, light, etc.; however, the inventive concept is not limited thereto.

[0054] The front surface of the display device DD may include a transmissive region TA and a border region BZA. The transmissive region TA may be the area through which an image IM is displayed. The user can view the image IM through the transmissive region TA. In this embodiment, the transmissive region TA may be a quadrilateral shape with rounded vertices; however, this is merely an example. The transmissive region TA can have various shapes and should not be particularly limited thereto.

[0055] The border region BZA may be adjacent to the transmissive region TA. The border region BZA may have a predetermined color. The border region BZA may surround the transmissive region TA. Therefore, the transmissive region TA may have a shape defined by the border region BZA; however, this is merely an example, and the border region BZA may be configured to be adjacent only to one side of the transmissive region TA, or it may be omitted. The display device DD according to embodiments of the present invention may include various embodiments and should not be particularly limited.

[0056] like Figure 2 and Figure 3 As shown, the display device DD may include a display module DM, a window WM, and an adhesive film AF. The display module DM may include a display panel DP and an input sensor ISP.

[0057] The display panel DP according to embodiments of the present invention can be a light-emitting display panel; however, the present invention is not limited thereto. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of an organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of a quantum dot light-emitting display panel may include quantum dots or quantum rods. In the following description, an organic light-emitting display panel will be used as a representative example of a display panel DP.

[0058] Reference Figure 3 The input sensor ISP can be disposed on the display panel DP. For example, the input sensor ISP can be directly disposed on the display panel DP. According to an embodiment of the present invention, the input sensor ISP can be formed on the display panel DP through a continuous process. For example, when the input sensor ISP is directly disposed on the display panel DP, an internal adhesive film may not be disposed between the input sensor ISP and the display panel DP. However, according to an embodiment of the present invention, an internal adhesive film can be disposed between the input sensor ISP and the display panel DP. In this case, the input sensor ISP is not manufactured together with the display panel DP through a continuous process. For example, the input sensor ISP can be manufactured with the display panel DP through a separate process and then fixed to the upper surface of the display panel DP by an internal adhesive film.

[0059] The display panel (DP) can generate images, and the input sensor (ISP) can obtain coordinate information of external inputs (e.g., touch events).

[0060] The window WM may include a transparent material that transmits images. For example, the window WM may include glass, sapphire, or plastic. The window WM may have a single-layer structure; however, the inventive concept is not limited thereto, and the window WM may include multiple layers. Furthermore, the bezel area BZA of the display device DD can be formed by printing a material with a predetermined color onto an area of ​​the window WM. As an example, the window WM may include a light-blocking pattern WBM to set the bezel area BZA. The light-blocking pattern WBM may be a colored organic layer and can be formed by a coating method.

[0061] The display module DM can be attached to the window WM via an adhesive film AF. As an example, the adhesive film AF may include an optically clear adhesive (OCA) film. However, the adhesive film AF should not be limited to this or by this, and the adhesive film AF may include different adhesives. For example, the adhesive film AF may include an optically clear resin (OCR) or pressure-sensitive adhesive (PSA) film.

[0062] The display device DD may also include an anti-reflection unit. The anti-reflection unit may be disposed on the input sensor ISP. The anti-reflection unit can reduce the reflectivity of external light incident on the window WM from above. An anti-reflection unit according to an embodiment of the present invention may include a retarder and / or a polarizer. The retarder may be film-type or liquid crystal coated type, and may include λ / 2 retarders and / or λ / 4 retarders. For example, the polarizer may be film-type or liquid crystal coated type. For example, a film-type polarizer may include a stretched synthetic resin film, and a liquid crystal coated polarizer may include liquid crystals arranged in a predetermined orientation. The retarder and polarizer may be implemented as a single polarizing film. The anti-reflection unit may also include a protective film disposed above or below the polarizing film.

[0063] The display module DM can display images in response to electrical signals and can transmit / receive information based on external input. The display module DM can include a valid area AA and a peripheral area NAA. The valid area AA can be the area through which an image provided by the display module DM is transmitted.

[0064] The peripheral region NAA can be adjacent to the effective region AA. For example, the peripheral region NAA can at least partially surround the effective region AA. However, this is merely an example, and the peripheral region NAA can be configured in various shapes and should not be particularly limited. According to an embodiment of the present invention, the effective region AA of the display module DM can correspond to at least a portion of the transmissive region TA.

[0065] The display module (DM) may include a main circuit board (MCB), a flexible circuit film (FCB), and a driver chip (DIC).

[0066] The main circuit board (MCB) can be connected to the flexible circuit film (FCB) and can be electrically connected to the display panel (DP). The main circuit board (MCB) may include multiple driving elements. The driving elements may include circuitry for driving the display panel (DP).

[0067] The flexible circuit film (FCB) can be connected to the display panel (DP), and the display panel (DP) can be electrically connected to the main circuit board (MCB). The driver chip (DIC) can be mounted on the flexible circuit film (FCB).

[0068] The driver chip DIC may include driving elements, such as data driving circuitry, for driving the pixels of the display panel DP. According to an embodiment of the present invention, the display module DM includes a flexible circuit film FCB; however, the present invention is not limited thereto or thereby. Multiple flexible circuit films FCBs may be provided, and multiple flexible circuit films FCBs may be connected to the display panel DP.

[0069] Figure 2 The diagram illustrates a structure in which the driver chip DIC is mounted on a flexible circuit film FCB; however, the inventive concept is not limited thereto or thereby restricted. For example, the driver chip DIC can be disposed on the display panel DP. As another example, the driver chip DIC can be disposed directly on the display panel DP. In this case, a portion of the display panel DP on which the driver chip DIC is mounted can be bent to be disposed on the rear surface of the display module DM.

[0070] The input sensor ISP can be electrically connected to the main circuit board MCB via a flexible circuit film FCB; however, embodiments of the present invention are not limited thereto. For example, the display module DM may also include a separate flexible circuit film to electrically connect the input sensor ISP to the main circuit board MCB.

[0071] The display device DD may also include a sensor controller to control the driving of the input sensor ISP. For example, the sensor controller may be built into the main circuit board MCB. However, as another example, the sensor controller may be built into the driver chip DIC. As yet another example, the sensor controller may be a circuit separate from both the main circuit board MCB and the driver chip DIC.

[0072] The display device DD may also include a housing EDC that houses the display module DM. The housing EDC may be attached to a window WM and may provide the appearance of the display device DD. The housing EDC can absorb impacts applied to it from the outside and can prevent foreign substances and moisture from entering the display module DM to protect the components housed within the housing EDC. Furthermore, as an example, the housing EDC may be configured as a combination of multiple storage components.

[0073] The display device DD according to an embodiment of the present invention may further include: an electronic module or circuit, including various functional modules or circuits for operating the display module DM; a power supply module or circuit for providing power for the overall operation of the display device DD; and a bracket connected to the display module DM and / or the housing EDC to divide the internal space of the display device DD.

[0074] Figure 4 This is a plan view illustrating a display panel DP according to an embodiment of the concept of the present invention.

[0075] Reference Figure 4 The display panel DP may include a drive circuit GDC, multiple signal lines SGL, and multiple pixels PX. The display panel DP may include a pad portion PLD disposed in the peripheral area NAA. The pad portion PLD may include pixel pads D-PD, each pixel pad D-PD being connected to a corresponding signal line in the signal lines SGL.

[0076] Pixels (PX) can be arranged within an effective area (AA). Each pixel (PX) may include an organic light-emitting diode (OLED) and pixel driving circuitry connected to the OLED. The driving circuitry (GDC), signal line (SGL), pad portion (PLD), and pixel driving circuitry may be included within... Figure 6 The circuit element layer DP-CL is shown.

[0077] The driving circuit GDC may include a gate driving circuit. For example, the gate driving circuit may generate multiple gate signals and sequentially output the gate signals to multiple gate lines GL, which will be described later. The gate driving circuit may also output other control signals to the pixel driving circuit.

[0078] The signal line SGL may include gate lines GL, data lines DL, power lines PL, and control signal lines CSL. Each of the gate lines GL can be connected to a corresponding pixel in pixel PX, and each of the data lines DL can be connected to a corresponding pixel in pixel PX. The power line PL can be connected to pixel PX. The control signal line CSL can provide control signals to the drive circuit GDC. The signal line SGL may overlap with the active area AA and the peripheral area NAA.

[0079] The pad portion of the PLD can be connected to the flexible circuit film FCB (see reference). Figure 2 It can include pixel pads (D-PD) and input pads (I-PD). The pixel pads (D-PD) connect the flexible circuit film (FCB) to the display panel (DP), and the input pads (I-PD) connect the flexible circuit film (FCB) to the input sensor (ISP) (see reference). Figure 2Pixel pads D-PD and input pads I-PD can be provided by exposing a portion of the lines disposed in the circuit element layer DP-CL without being covered by the insulating layer included in the circuit element layer DP-CL.

[0080] The pixel pad (D-PD) can be connected to the corresponding pixel (PX) via the signal line (SGL). Additionally, the drive circuit (GDC) can be connected to one of the pixel pads in the pixel pad (D-PD).

[0081] Figure 5 This is a plan view illustrating an input sensor ISP according to an embodiment of the present invention. (Refer to...) Figure 5 The input sensor ISP can include multiple sensing electrodes IE and multiple traces SL. The sensing electrodes IE have their own coordinate information. The sensing electrodes IE can be arranged in a first direction DR1 and a second direction DR2. For example, the sensing electrodes IE can be arranged in a matrix, and each can be connected to a trace SL.

[0082] The input sensor ISP may include input pads I-PD, each of which may be connected to one end of a corresponding trace SL among a plurality of traces SL, and may be arranged in the peripheral area NAA.

[0083] The input sensor ISP according to this embodiment can obtain coordinate information, for example, through a self-capacitance method. Sensing electrodes IE are connected to input pads I-PD via traces SL. Each of the sensing electrodes IE can be connected to a sensor controller via the input pads I-PD. The capacitance of each of the sensing electrodes IE can be changed by an external input (e.g., a touch event). In this embodiment, the sensitivity of the input sensor ISP can be determined based on the change in capacitance. For example, the sensitivity of the input sensor ISP can be increased as the capacitance change caused by the external input increases.

[0084] The shape and arrangement of the sensing electrodes IE should not be limited. As an example, each of the sensing electrodes IE may have a polygonal shape, and a sensing electrode IE with a quadrilateral shape is shown as a representative example. As an example, each of the sensing electrodes IE may include a touch electrode. The shape and arrangement of the sensing electrodes IE may depend on the arrangement of the touch electrodes according to the pixel PX described later (refer to...). Figure 4 The arrangement was changed.

[0085] The sensing electrodes IE and traces SL can be positioned within the effective region AA. For example, a portion of each of the traces SL can be positioned within the effective region AA, and another portion of each of the traces SL can be positioned within the peripheral region NAA.

[0086] Figure 6 This is a cross-sectional view showing a display panel DP according to an embodiment of the present invention. (Refer to...) Figure 6 A display panel (DP) may include multiple intermediate insulating layers, semiconductor patterns, conductive patterns, and signal lines. The intermediate insulating layers, semiconductor patterns, and conductive patterns can be formed through coating or deposition processes. For example, the intermediate insulating layers, semiconductor patterns, and conductive patterns can be selectively patterned using a photolithography process. This allows the formation of semiconductor patterns, conductive patterns, and signal lines included in the circuit element layer (DP-CL) and the light-emitting element layer (DP-OLED).

[0087] The circuit element layer DP-CL may include a base layer BL, a buffer layer BFL, a first intermediate insulating layer IL1, a second intermediate insulating layer IL2, a third intermediate insulating layer IL3, and a fourth intermediate insulating layer IL4.

[0088] The base layer BL may include a synthetic resin film. For example, the synthetic resin film may include a thermosetting resin. The base layer BL may have a multilayer structure. For example, the base layer BL may have a three-layer structure consisting of a synthetic resin layer, an adhesive layer, and a synthetic resin layer. For example, the synthetic resin layer may be a polyimide-based resin layer; however, the material used for the synthetic resin layer is not limited. The synthetic resin layer may include, for example, at least one of acrylic acid-based resins, methacrylic acid-based resins, polyisoprene-based resins, ethylene-based resins, epoxy-based resins, urethane-based resins, cellulose-based resins, siloxane-based resins, polyamide-based resins, and dinaphthalene-based resins. The base layer BL may include a glass substrate, a metal substrate, or an organic / inorganic composite substrate.

[0089] At least one inorganic layer may be formed on the upper surface of the base layer BL. For example, the inorganic layer may include at least one of alumina, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide. The inorganic layer may be formed in multiple layers. The inorganic layer may form a barrier layer and / or a buffer layer. In this embodiment, the display panel DP may include a buffer layer BFL.

[0090] The buffer layer (BFL) can increase the adhesion between the base layer (BL) and the semiconductor pattern. The buffer layer (BFL) can, for example, include a silicon oxide layer and a silicon nitride layer, and the silicon oxide layer and silicon nitride layer can be stacked alternately on top of each other.

[0091] Semiconductor patterns can be disposed on the buffer layer BFL. The semiconductor pattern may include polycrystalline silicon; however, the inventive concept is not limited thereto or thereby restricted. For example, the semiconductor pattern may include amorphous silicon or metal oxide.

[0092] Figure 6Only a portion of the semiconductor pattern is shown, and the semiconductor pattern can be disposed in other regions of the pixel in a plane. The semiconductor pattern can be disposed on the pixel PX. The semiconductor pattern can have different electrical properties depending on whether it is doped and whether it is doped with N-type or P-type dopant. The semiconductor pattern can include a first region and a second region. The first region can have relatively high conductivity, and the second region can have relatively low conductivity. For example, the first region can be doped with N-type or P-type dopant. A P-type transistor can include a doped region doped with P-type dopant. For example, the second region can be an undoped region, or it can be doped at a lower concentration than the first region.

[0093] The first region can have a higher conductivity than the second region and can be essentially used as an electrode or signal line. The second region can essentially correspond to the active region (or, for example, the channel region) of a transistor. For example, a portion of the semiconductor pattern can be the active region of a transistor. Another portion of the semiconductor pattern can be the source or drain region of a transistor, and the remainder of the semiconductor pattern can be a connection electrode or a connection signal line.

[0094] like Figure 6 As shown, a first source region SE1, a first active region CHA1, and a first drain region DE1 of a first transistor TR1 can be formed from a semiconductor pattern, and a second source region SE2, a second active region CHA2, and a second drain region DE2 of a second transistor TR2 can be formed from the semiconductor pattern. The first source region SE1 and the first drain region DE1 can extend from the first active region CHA1 in opposite directions, and the second source region SE2 and the second drain region DE2 can extend from the second active region CHA2 in opposite directions. For example, the first active region CHA1 can be disposed between the first source region SE1 and the first drain region DE1, and the second active region CHA2 can be disposed between the second source region SE2 and the second drain region DE2.

[0095] A first intermediate insulating layer IL1 may be disposed on the buffer layer BFL. For example, the first intermediate insulating layer IL1 may commonly overlap with multiple pixels PX and may cover a semiconductor pattern; however, the inventive concept is not limited thereto, and for example, the first intermediate insulating layer IL1 may be divided into separate portions. The first intermediate insulating layer IL1 may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multilayer structure. The first intermediate insulating layer IL1 may include at least one of alumina, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide. In this embodiment, the first intermediate insulating layer IL1 may, for example, have a single-layer structure having a silicon oxide layer. Not only the first intermediate insulating layer IL1, but also the intermediate insulating layer described later in the circuit element layer DP-CL may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multilayer structure. The inorganic layer may include at least one of the materials described above.

[0096] A first gate GE1 and a second gate GE2 may be disposed on a first intermediate insulating layer IL1. The first gate GE1 may correspond to a portion of a metal pattern. The first gate GE1 and the second gate GE2 may overlap with a first active region CHA1 and a second active region CHA2, respectively. The first gate GE1 and the second gate GE2 may be used as masks in a process of doping a semiconductor pattern.

[0097] The second intermediate insulating layer IL2 may be disposed on the first intermediate insulating layer IL1 and may cover the first gate GE1 and the second gate GE2. The second intermediate insulating layer IL2 commonly overlaps with a plurality of pixels PX; however, the inventive concept is not limited thereto, and for example, the second intermediate insulating layer IL2 may be divided into separate portions. The second intermediate insulating layer IL2 may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multi-layer structure. In this embodiment, the second intermediate insulating layer IL2 may, for example, have a single-layer structure having a silicon oxide layer.

[0098] The first connecting electrode SD1 can be disposed on the second intermediate insulating layer IL2. The first connecting electrode SD1 can be connected to the second drain region DE2 via a first contact hole CNT-1 configured to pass through the first intermediate insulating layer IL1 and the second intermediate insulating layer IL2.

[0099] The third intermediate insulating layer IL3 can be disposed on the second intermediate insulating layer IL2. The third intermediate insulating layer IL3 can be an organic layer. The second connecting electrode SD2 can be disposed on the third intermediate insulating layer IL3. The second connecting electrode SD2 can be connected to the first connecting electrode SD1 through the second contact hole CNT-2 configured to pass through the third intermediate insulating layer IL3.

[0100] The fourth intermediate insulating layer IL4 can be disposed on the third intermediate insulating layer IL3 and can cover the second connecting electrode SD2. For example, the fourth intermediate insulating layer IL4 can be an organic layer.

[0101] The DP-OLED light-emitting element layer can be disposed on the DP-CL circuit element layer. As an example, the DP-OLED light-emitting element layer may include a light-emitting element OLED and a pixel-defining layer PDL.

[0102] An OLED (Optical Display Panel) may include a first electrode AE, an emissive layer EL, and a second electrode CE. The first electrode AE ​​may be disposed on the circuit element layer DP-CL. The emissive layer EL may be disposed on the first electrode AE, and the second electrode CE may be disposed on the emissive layer EL.

[0103] The first electrode AE ​​can be disposed on the fourth intermediate insulating layer IL4. The first electrode AE ​​can be connected to the second connecting electrode SD2 through a third contact hole CNT-3 configured to pass through the fourth intermediate insulating layer IL4. An opening OP2 (hereinafter referred to as a pixel opening) can be provided through a pixel defining layer PDL. At least a portion of the first electrode AE ​​can be exposed through the pixel opening OP2 of the pixel defining layer PDL.

[0104] like Figure 6 As shown, the display panel DP may include a light-emitting region PXA and a non-light-emitting region NPXA surrounding the light-emitting region PXA. The non-light-emitting region NPXA may at least partially surround the light-emitting region PXA. In this embodiment, the light-emitting region PXA may correspond to the portion of the first electrode AE ​​exposed through the pixel opening OP2.

[0105] The light-emitting layer EL can be disposed on the first electrode AE. The light-emitting layer EL can be disposed in the region corresponding to the pixel opening OP2. For example, the light-emitting layer EL can be formed in the pixel PX (refer to...) in the form of being divided into multiple parts. Figure 4 Each of the following is a sequence of characters.

[0106] The second electrode CE can be disposed on the light-emitting layer EL. The second electrode CE can have a monolithic shape and can be disposed on multiple pixels PX.

[0107] An encapsulation layer TFE can be disposed on the second electrode CE. The encapsulation layer TFE is commonly disposed on multiple pixels PX. In this embodiment, the encapsulation layer TFE can cover the second electrode CE. For example, the encapsulation layer TFE can be directly disposed on the second electrode CE. However, the inventive concept is not limited thereto. In embodiments of the inventive concept, a capping layer can be disposed between the encapsulation layer TFE and the second electrode CE to cover the second electrode CE. In this case, the encapsulation layer TFE can cover the capping layer and can be indirectly disposed on the second electrode CE.

[0108] As an example, the OLED light-emitting element may also include a hole control layer and an electron control layer. The hole control layer may be disposed between the first electrode AE ​​and the light-emitting layer EL, and may also include a hole injection layer. The electron control layer may be disposed between the light-emitting layer EL and the second electrode CE, and may also include an electron injection layer. The hole control layer and the electron control layer may be commonly formed in multiple pixels PX using an aperture mask.

[0109] Figures 7A to 7C It shows the input sensor and Figure 5 A magnified plan view of a portion corresponding to region AA'.

[0110] Reference Figure 7A Each of the sensing electrodes IE can include multiple first touch electrodes SIE1 and multiple second touch electrodes SIE2. The first touch electrodes SIE1 overlap with the non-light-emitting region NPXA. The second touch electrodes SIE2 overlap with the light-emitting region PXA and the non-light-emitting region NPXA, and are electrically connected to the first touch electrodes SIE1. Each of the first touch electrodes SIE1 and the second touch electrodes SIE2 can include a metallic material or a transparent conductive material. Metallic materials can include, for example, silver, aluminum, copper, chromium, nickel, titanium, etc., which can be processed at low temperatures; however, the inventive concept is not limited thereto or thereby restricted. Transparent conductive materials can include transparent conductive oxides, such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium zinc tin oxide (ITZO), etc. Furthermore, transparent conductive materials can include conductive polymers, such as PEDOT, metal nanowires, graphene, etc. When the first touch electrodes SIE1 and the second touch electrodes SIE2 include metallic materials that can be processed at low temperatures, damage to the light-emitting element OLED can be prevented even if the input sensor ISP is formed through a continuous process.

[0111] OLED (Light Emitting Element) Figure 6 It may include: a first light-emitting element OLED1 (refer to...) Figure 8B ), emitting first light with a first wavelength band; the second light-emitting element OLED2 (refer to Figure 8B), emitting a second light having a second wavelength band different from the first wavelength band; and a third light-emitting element OLED3 (see Figure 8B It emits a third light with a third wavelength band that is different from the first and second wavelength bands. For example, the first light can be red light, the second light can be green light, and the third light can be blue light.

[0112] The light-emitting region PXA can be divided into multiple regions based on the light-emitting element OLED disposed therein. The light-emitting region PXA containing the first light-emitting element OLED1 can be referred to as the first light-emitting region PXA1. The light-emitting region PXA containing the second light-emitting element OLED2 can be referred to as the second light-emitting region PXA2, and the light-emitting region PXA containing the third light-emitting element OLED3 can be referred to as the third light-emitting region PXA3. The sizes of the first light-emitting regions PXA1 to the third light-emitting regions PXA3 can vary according to the color of the light generated by the first light-emitting element OLED1 to the third light-emitting element OLED3. The sizes of the first light-emitting regions PXA1 to the third light-emitting regions PXA3 can be determined according to the type of light-emitting layer EL included in the light-emitting element OLED. For example, when the first light, the second light, and the third light are red light, green light, and blue light, respectively, the size of the third light-emitting region PXA3 can be larger than the sizes of the first light-emitting region PXA1 and the second light-emitting region PXA2, and the size of the first light-emitting region PXA1 can be larger than the size of the second light-emitting region PXA2. This is because organic materials emitting red light have the best efficiency, while organic materials emitting blue light have the worst efficiency. In this embodiment, first emitting regions PXA1 to third emitting regions PXA3 with different sizes are shown as representative examples; however, the inventive concept is not limited thereto or thereby restricted. For example, the first emitting regions PXA1 to third emitting regions PXA3 may have the same size as each other.

[0113] The first touch electrode SIE1 may extend in a first direction DR1, may be arranged in a second direction DR2, and may be disposed in a non-light-emitting region NPXA surrounding the first light-emitting region PXA1 to the third light-emitting region PXA3. Each of the first touch electrodes SIE1 may include a first sub-touch electrode SIE1_a and a second sub-touch electrode SIE1_b, which extend in the first direction DR1 and are arranged in the second direction DR2. Furthermore, the first touch electrode SIE1 may at least partially surround the light-emitting regions PXA1 to PXA3. An opening OP1 (hereinafter referred to as an electrode opening) may be provided between the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b to at least partially expose the light-emitting region PXA. The size of the electrode opening OP1 may vary depending on the first light-emitting region PXA1 to the third light-emitting region PXA3 surrounded by the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b. As an example, when the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b surround the first light-emitting region PXA1, the electrode opening OP1 can be the first electrode opening OP1_a. When the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b surround the second light-emitting region PXA2, the electrode opening OP1 can be the second electrode opening OP1_b. When the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b surround the third light-emitting region PXA3, the electrode opening OP1 can be the third electrode opening OP1_c. In this case, for example, the size of the third electrode opening OP1_c can be larger than the size of the first electrode opening OP1_a and the second electrode opening OP1_b, and the size of the first electrode opening OP1_a can be larger than the size of the second electrode opening OP1_b. In this embodiment, the first electrode opening OP1_a to the third electrode opening OP1_c having different sizes are shown as representative examples; however, the inventive concept is not limited to this or thus restricted. For example, the first electrode opening OP1_a to the third electrode opening OP1_c can have the same size as each other.

[0114] The second touch electrode SIE2 can extend along the first direction DR1 and can be arranged along the second direction DR2. Each of the second touch electrodes SIE2 can overlap with the light-emitting area PXA and the non-light-emitting area NPXA. As an example, the first light-emitting areas PXA1 to the third light-emitting areas PXA3 are on the display panel DP (refer to...). Figure 4 The light-emitting areas are arranged sequentially along the first direction DR1, and the same type of light-emitting areas can be arranged in the same row along the second direction DR2. For example, the first light-emitting area PXA1 can be arranged in the first row, and the second light-emitting area PXA2 can be arranged in the second row. As another example, the third light-emitting area PXA3 can be arranged in the third row.

[0115] Compared to an example where each sensing electrode IE includes only a first touch electrode SIE1 overlapping the non-light-emitting region NPXA, in the case where each sensing electrode IE includes both a first touch electrode SIE1 and a second touch electrode SIE2 overlapping the light-emitting region PXA, the number and area of ​​the first touch electrodes SIE1 and SIE2 included in one sensing electrode IE can be increased. Therefore, the sensitivity of the input sensor ISP can be improved. For example, compared to display devices with small screens (such as smartphones), display devices with large screens (such as televisions) have large gaps between pixels, even if they have the same display resolution. Therefore, the gaps between the first touch electrodes SIE1 may increase, the number of first touch electrodes SIE1 included in one sensing electrode IE may decrease, and as a result, the sensitivity of the input sensor ISP may decrease. In this case, when each sensing electrode IE also includes a second touch electrode SIE2, the sensitivity of the input sensor ISP can be improved.

[0116] However, when the second touch electrode SIE2 is made of a metallic material, the light generated from the first light-emitting area PXA1 to the third light-emitting area PXA3 can be reflected by the second touch electrode SIE2 and may not penetrate to the outside. In this case, when the first light-emitting area PXA1 to the third light-emitting area PXA3 have different sizes, and when the second touch electrode SIE2 is arranged to overlap with the first light-emitting area PXA1 to the third light-emitting area PXA3 with the same width, the amount of light that cannot penetrate to the outside may vary depending on the color of the emitted light, thus affecting the user's visibility. According to the present invention, the width of the second touch electrode SIE2 can vary depending on the light-emitting area it overlaps with.

[0117] For example, each of the second touch electrodes SIE2 may include a first portion LP1a overlapping the first light-emitting region PXA1, a second portion LP2a overlapping the second light-emitting region PXA2, and a third portion LP3a overlapping the third light-emitting region PXA3. At least one of the first portions LP1a to the third portions LP3a may have a width larger than the remaining portions. For example, when the first light, the second light, and the third light are red light, green light, and blue light, respectively, the size of the third light-emitting region PXA3 corresponding to blue light may be larger than the size of each of the first light-emitting region PXA1 corresponding to red light and the second light-emitting region PXA2 corresponding to green light, and the size of the first light-emitting region PXA1 may be larger than the size of the second light-emitting region PXA2. In this case, the width WD3a of the third portion LP3a may be larger than the width WD1a of the first portion LP1a and the width WD2a of the second portion LP2a, and the width WD1a of the first portion LP1a may be larger than the width WD2a of the second portion LP2a. By varying the width of each of the second touch electrodes SIE2 according to the size of the overlapping light-emitting area, the rate of light that cannot penetrate to the outside due to the second touch electrodes SIE2 can be the same for each color. Therefore, although the second touch electrodes SIE2 are configured to overlap with the light-emitting area PXA, it can still maintain the user's visibility.

[0118] Reference Figure 7B Each of the second touch electrodes SIE2 may include a first sensing portion SP1 and a second sensing portion SP2. The first sensing portion SP1 may overlap with at least one of the first light-emitting regions PXA1 to the third light-emitting region PXA3, and the second sensing portion SP2 may be connected to the first sensing portion SP1 and may overlap with the non-light-emitting region NPXA. In the following text, the terms "and" will be omitted. Figure 7A The same components are described in detail.

[0119] As an example, Figure 7BThe diagram illustrates the structure of a first sensing portion SP1 in each of the second touch electrodes SIE2 that overlaps with the first light-emitting region PXA1 and the third light-emitting region PXA3, and a second sensing portion SP2 that overlaps with the non-light-emitting region NPXA and does not overlap with the second light-emitting region PXA2. The first sensing portion SP1 may include a first sub-sensing portion SP1_a and a second sub-sensing portion SP1_b. The first sub-sensing portion SP1_a may overlap with the first light-emitting region PXA1, and the second sub-sensing portion SP1_b may overlap with the third light-emitting region PXA3. In embodiments of the inventive concept, the size of the second light-emitting region PXA2 is minimal, and therefore, the impact on user visibility is greatest when the second touch electrode SIE2 overlaps with the second light-emitting region PXA2. Therefore, the second touch electrode SIE2 may be configured not to overlap with the second light-emitting region PXA2. However, the inventive concept is not limited to this or thus restricted. Each of the second touch electrodes SIE2 may not overlap with the first light-emitting region PXA1. Furthermore, the first sensing portion SP1 may have a width that varies depending on the light-emitting region it overlaps with. The second sensing portion SP2 can be located in the non-light-emitting area NPXA and can be spaced apart from each of the first touch electrodes SIE1.

[0120] Reference Figure 7C As an example, the first luminous area PXA1 to the third luminous area PXA3 can be arranged sequentially in the display panel DP along the second direction DR2, and luminous areas of the same type can be arranged in the same column along the first direction DR1. In the following text, the terms "and" will be omitted. Figure 7A The same components are described in detail.

[0121] Each of the second touch electrodes SIE2 may include a third sub-touch electrode SIE2_a, a fourth sub-touch electrode SIE2_b, and a fifth sub-touch electrode SIE2_c extending in the first direction DR1. The third sub-touch electrode SIE2_a may overlap with the first light-emitting region PXA1. The fourth sub-touch electrode SIE2_b may overlap with the second light-emitting region PXA2, and the fifth sub-touch electrode SIE2_c may overlap with the third light-emitting region PXA3.

[0122] The third sub-touch electrode SIE2_a may include multiple first portions LP1b, and the fourth sub-touch electrode SIE2_b may include multiple second portions LP2b. The fifth sub-touch electrode SIE2_c may include multiple third portions LP3b.

[0123] However, the first light-emitting region PXA1 to the third light-emitting region PXA3 can be arranged in various ways in the display panel DP of the present invention, and are not limited to these arrangements. Figures 7A to 7CThe embodiment shown in Figure 9A. As an example, the first to third light-emitting regions can be configured in accordance with Figure 9A. Figure 9B , Figure 10A and Figure 10B The luminous areas shown are arranged in the same way.

[0124] Figure 8A It is along Figure 7A The sectional view shown by line II-II' is used to illustrate the display module DM, and Figure 8B It is along Figure 7C The section view shown by line III-III' is used to illustrate the display module DM.

[0125] Reference Figure 8A The display module DM may include a display panel DP and an input sensor ISP disposed on the display panel DP. For example, the input sensor ISP may be directly disposed on the display panel DP. References will be omitted below. Figure 6 A detailed description of the same element as the described element.

[0126] The input sensor ISP can be formed on the display panel DP through a continuous process. The input sensor ISP may include a first sensing insulating layer IIL1, a conductive layer ICL, and a second sensing insulating layer IIL2.

[0127] The first sensing insulating layer IIL1 may be an inorganic layer comprising one of silicon nitride, silicon oxynitride, and silicon oxide. Alternatively, the first sensing insulating layer IIL1 may include an organic layer, comprising an epoxy-based resin, an acrylic-based resin, or an imide-based resin. The first sensing insulating layer IIL1 may have a monolayer structure or a multilayer structure having multiple layers stacked on a third-direction DR3.

[0128] A conductive layer ICL may be disposed on a first sensing insulating layer IIL1. As an example, the conductive layer ICL may include a sensing electrode IE. The conductive layer ICL may be covered by a second sensing insulating layer IIL2.

[0129] The conductive layer ICL can have a single-layer structure or a multilayer structure with multiple layers stacked on a third-direction DR3. A single-layer conductive layer ICL can include a metal layer or a transparent conductive layer. The metal layer can include molybdenum, silver, titanium, copper, aluminum, or alloys thereof. The transparent conductive layer can include transparent conductive oxides, such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium zinc tin oxide (ITZO), etc. Furthermore, the transparent conductive layer can include conductive polymers such as PEDOT, metal nanowires, graphene, etc.

[0130] A conductive layer ICL with a multilayer structure may include a metal layer. The metal layer may have a titanium / aluminum / titanium three-layer structure. A conductive layer ICL with a multilayer structure may include at least one metal layer and at least one transparent conductive layer.

[0131] The second sensing insulating layer IIL2 may include an inorganic layer. The inorganic layer may include at least one of alumina, titanium dioxide, silicon dioxide, silicon oxynitride, zirconium oxide, and hafnium oxide. The second sensing insulating layer IIL2 may also include an organic layer. The organic layer may include at least one of an acrylic acid-based resin, a methacrylic acid-based resin, a polyisoprene-based resin, an ethylene-based resin, an epoxy-based resin, a urethane-based resin, a cellulose-based resin, a siloxane-based resin, a polyimide-based resin, a polyamide-based resin, and a dinoflagellate-based resin.

[0132] The width of the electrode opening OP1 in the second direction DR2 can be substantially equal to the distance between the first sub-touch electrode SIE1_a and the second sub-touch electrode SIE1_b.

[0133] Reference Figure 8B The pixel aperture OP2 may include a first pixel aperture OP2_a, a second pixel aperture OP2_b, and a third pixel aperture OP2_c. In the first pixel aperture OP2_a, at least a portion of the first electrode AE1 of the first light-emitting element OLED1 is exposed, and the first light-emitting layer EL1 may be disposed on the first electrode AE1. In the second pixel aperture OP2_b, at least a portion of the first electrode AE2 of the second light-emitting element OLED2 is exposed, and the second light-emitting layer EL2 may be disposed on the first electrode AE2. In the third pixel aperture OP2_c, at least a portion of the first electrode AE3 of the third light-emitting element OLED3 is exposed, and the third light-emitting layer EL3 may be disposed on the first electrode AE3. References will be omitted below. Figure 6 A detailed description of the same element as described above.

[0134] The first pixel opening OP2_a to the third pixel opening OP2_c can have different sizes. For example, when the first light, the second light, and the third light are red light, green light, and blue light, respectively, the size of the third pixel opening OP2_c is larger than each of the sizes of the first pixel opening OP2_a and the second pixel opening OP2_b, and the size of the first pixel opening OP2_a can be larger than the size of the second pixel opening OP2_b. The first light-emitting regions PXA1 to PXA3 corresponding to the portions of the first electrodes AE1 to AE3 exposed through the first pixel opening OP2_a to the third pixel opening OP2_c can have different sizes. For example, when the first light, the second light, and the third light are red light, green light, and blue light, respectively, the size of the third light-emitting region PXA3 corresponding to blue light can be larger than each of the sizes of the first light-emitting region PXA1 corresponding to red light and the second light-emitting region PXA2 corresponding to green light, and the size of the first light-emitting region PXA1 can be larger than the size of the second light-emitting region PXA2.

[0135] The third sub-touch electrode SIE2_a, the fourth sub-touch electrode SIE2_b, and the fifth sub-touch electrode SIE2_c can have different widths from each other. For example, the third sub-touch electrode SIE2_a can overlap with the first light-emitting region PXA1. As another example, the fourth sub-touch electrode SIE2_b can overlap with the second light-emitting region PXA2, and the fifth sub-touch electrode SIE2_c can overlap with the third light-emitting region PXA3. The width WD3b of the fifth sub-touch electrode SIE2_c can be greater than each of the widths WD1b of the third sub-touch electrode SIE2_a and WD2b of the fourth sub-touch electrode SIE2_b. The width WD1b of the third sub-touch electrode SIE2_a can be greater than the width WD2b of the fourth sub-touch electrode SIE2_b. As an example, the width WD1b of the third sub-touch electrode SIE2_a can be a first portion LP1b included in the third sub-touch electrode SIE2_a (see reference). Figure 7C The width WD1b of each of the four sub-touch electrodes SIE2_b. The width WD2b of the fourth sub-touch electrode SIE2_b can be the second part LP2b included in the fourth sub-touch electrode SIE2_b (see reference). Figure 7C The width WD2b of each of the five sub-touch electrodes SIE2_c, and the width WD3b of the fifth sub-touch electrode SIE2_c may be the third part LP3b included in the fifth sub-touch electrode SIE2_c (see reference). Figure 7C The width of each of them is WD3b.

[0137] Reference Figure 9A The first luminous area PXA1 and the third luminous area PXA3 can be displayed on the DP (refer to) display panel. Figure 4 The first luminescent region PXA1 and the second luminescent region PXA2 are arranged sequentially in the first direction DR1 and the second direction DR2, and the second luminescent region PXA2 can be arranged to be spaced apart from the first luminescent region PXA1 and the third luminescent region PXA3 in the fourth direction DR4, which intersects the first direction DR1 and the second direction DR2. In the following text, references to the first luminescent region PXA1 and the second luminescent region PXA3 will be omitted. Figures 7A to 7C A detailed description of the same element as the described element.

[0138] Each of the second touch electrodes SIE2 may include a third sub-touch electrode SIE2_a and a fourth sub-touch electrode SIE2_b. The third sub-touch electrode SIE2_a may overlap with the first light-emitting region PXA1, the third light-emitting region PXA3, and the non-light-emitting region NPXA, and may include a first portion LP1c overlapping with the first light-emitting region PXA1 and a third portion LP3c overlapping with the third light-emitting region PXA3. The fourth sub-touch electrode SIE2_b may overlap with the second light-emitting region PXA2 and the non-light-emitting region NPXA, and may include a second portion LP2c overlapping with the second light-emitting region PXA2. The fourth sub-touch electrode SIE2_b may be positioned in a direction different from the first direction DR1, spaced apart from the first touch electrode SIE1 in the non-light-emitting region NPXA. For example, there may be space between the fourth sub-touch electrode SIE2_b and the first touch electrode SIE1 in the second direction DR2. Figure 9A As shown, the width WD3c of the third part LP3c can be greater than the width WD1c of the first part LP1c and the width WD2c of the second part LP2c, and the width WD1c of the first part LP1c can be greater than the width WD2c of the second part LP2c.

[0139] Reference Figure 9BEach of the second touch electrodes SIE2, including a third sub-touch electrode SIE2_a and a fourth sub-touch electrode SIE2_b, may not overlap with the first light-emitting regions PXA1 to PXA3. The second touch electrodes SIE2 may be disposed between adjacent first and second sub-touch electrodes SIE1_a and SIE1_b, and may be configured not to overlap with the first and third light-emitting regions PXA1 to PXA3. For example, the third sub-touch electrode SIE2_a of the second touch electrode SIE2 may be disposed between the first and second sub-touch electrodes SIE1_a and SIE1_b of the first touch electrode SIE1, and may include a first portion LP1d adjacent to the first light-emitting region PXA1 and a third portion LP3d adjacent to the third light-emitting region PXA3. For example, the fourth sub-touch electrode SIE2_b of the second touch electrode SIE2 may include a second portion LP2d adjacent to the second light-emitting region PXA2. Therefore, since the second touch electrode SIE2 is further disposed in each of the sensing electrodes IE, the sensitivity of the input sensor ISP can be improved, and the user's visibility can be prevented from being affected by the second touch electrode SIE2. As shown in FIG9B, the width WD3d of the third portion LP3d can be greater than the width WD1d of the first portion LP1d and the width WD2d of the second portion LP2d, and the width WD1d of the first portion LP1d can be greater than the width WD2d of the second portion LP2d.

[0140] Reference Figure 10A and Figure 10B The first luminous area PXA1 and the second luminous area PXA2 can be displayed on the DP (refer to) display panel. Figure 6 The first light-emitting region PXA1 and the second light-emitting region PXA2 are arranged in the second direction DR2, and the third light-emitting region PXA3 can be spaced apart from the first light-emitting region PXA1 and the second light-emitting region PXA2 in the first direction DR1, and can also be arranged in the second direction DR2. For example, the first light-emitting region PXA1 and the second light-emitting region PXA2 can be arranged sequentially in the second direction DR2; however, the inventive concept is not limited thereto. In the following, references to Figures 7A to 7B will be omitted. Figure 7C A detailed description of the same element as the described element.

[0141] Reference Figure 10AThe first touch electrode SIE1 can be arranged in the non-light-emitting region NPXA along the first direction DR1 and the second direction DR2. The second touch electrode SIE2 can include a third sub-touch electrode SIE2_a and a fourth sub-touch electrode SIE2_b, and can be arranged along the first direction DR1. For example, the third sub-touch electrode SIE2_a and the fourth sub-touch electrode SIE2_b can each extend along the second direction DR2. The third sub-touch electrode SIE2_a can overlap with the first light-emitting region PXA1, the second light-emitting region PXA2, and the non-light-emitting region NPXA, and can include a first portion LP1e overlapping with the first light-emitting region PXA1 and a second portion LP2e overlapping with the second light-emitting region PXA2. The fourth sub-touch electrode SIE2_b can overlap with the third light-emitting region PXA3 and the non-light-emitting region NPXA, and can include a third portion LP3e overlapping with the third light-emitting region PXA3. Figure 10A As shown, the width WD3e of the third part LP3e can be greater than the width WD1e of the first part LP1e and the width WD2e of the second part LP2e, and the width WD1e of the first part LP1e can be greater than the width WD2e of the second part LP2e.

[0142] Reference Figure 10B The first touch electrode SIE1 can be disposed along the second direction DR2 in the non-light-emitting region NPXA. The second touch electrode SIE2 may include a third sub-touch electrode SIE2_a, a fourth sub-touch electrode SIE2_b, a fifth sub-touch electrode SIE2_c, and a sixth sub-touch electrode SIE2_d, and can be arranged on the second direction DR2. For example, the third sub-touch electrode SIE2_a, the fourth sub-touch electrode SIE2_b, the fifth sub-touch electrode SIE2_c, and the sixth sub-touch electrode SIE2_d can extend on the first direction DR1. The third sub-touch electrode SIE2_a can overlap with the first light-emitting region PXA1, the third light-emitting region PXA3, and the non-light-emitting region NPXA. The fourth sub-touch electrode SIE2_b can overlap with the second light-emitting region PXA2, the third light-emitting region PXA3, and the non-light-emitting region NPXA. The fifth sub-touch electrode SIE2_c can overlap with the third light-emitting region PXA3 and the non-light-emitting region NPXA. The sixth sub-touch electrode SIE2_d may not overlap with the first light-emitting regions PXA1 to the third light-emitting regions PXA3, but may overlap with the non-light-emitting region NPXA. For example... Figure 10BAs shown, the portion of the second touch electrode SIE2 that overlaps with the first light-emitting region PXA1 may have a width WD1f, the portion of the second touch electrode SIE2 that overlaps with the second light-emitting region PXA2 may have a width WD2f, and the portion of the second touch electrode SIE2 that overlaps with the third light-emitting region PXA3 may have a width WD3f. Width WD3f may be greater than each of widths WD1f and WD2f, and width WD1f may be greater than width WD2f.

[0143] Reference Figure 10A and Figure 10B The first touch electrode SIE1 can include multiple electrodes electrically connected to each other via the second touch electrode SIE2, instead of being configured as a single electrode. When the first touch electrode SIE1 includes multiple electrodes, the level of parasitic capacitance between the first touch electrode SIE1 and the electrodes of the display panel DP can be reduced. Furthermore, when the first touch electrode SIE1 is made of a metallic material, it can be seen from the outside even if it is located in the non-light-emitting area NPXA. Therefore, when the first touch electrode SIE1 is formed by multiple electrodes electrically connected to each other instead of a single electrode, it can prevent the first touch electrode SIE1 from being seen from the outside.

[0144] Figure 11 This shows the input sensor and Figure 5 An enlarged plan view of a portion corresponding to region AA'. In the following text, references to... Figure 7A A detailed description of the same element as the described element.

[0145] Reference Figure 4 and Figure 11 As the resolution of the display panel (DP) increases, the number of pixels (PX) within a unit area can increase, and the size of the non-light-emitting area (NPXA) surrounding the light-emitting area (PXA) can decrease. Therefore, in situations such as... Figure 7A The process of placing the first touch electrode SIE1 in the non-light-emitting region NPXA, or separating the first touch electrodes SIE1 from each other, as shown, may encounter difficulties. In this case, each of the sensing electrodes IE (see Figure 5) may not include the first touch electrode SIE1, but may instead include a second touch electrode SIE2 that overlaps with the light-emitting region PXA and the non-light-emitting region NPXA. For example, the second touch electrode SIE2 may include a first portion LP1g that overlaps with the first light-emitting region PXA1, a second portion LP2g that overlaps with the second light-emitting region PXA2, and a third portion LP3g that overlaps with the third light-emitting region PXA3. Figure 11As shown, the width WD3g of the third portion LP3g can be greater than the width WD1g of the first portion LP1g and the width WD2g of the second portion LP2g, and the width WD1g of the first portion LP1g can be greater than the width WD2g of the second portion LP2g. The second touch electrode SIE2 can be configured to overlap with the light-emitting area PXA, and therefore, even if the resolution of the display panel DP increases, there will be no difficulties in the manufacturing process.

[0146] Figure 12 This is a plan view illustrating an input sensor ISP according to an embodiment of the present invention. References will be omitted below. Figure 5 A detailed description of the same element as the described element.

[0147] Reference Figure 12 An input sensor ISP according to an embodiment of the present invention may include receiving sensing electrodes IE1-1 to IE1-5, receiving traces SL1-1 to SL1-5 connected to the receiving sensing electrodes IE1-1 to IE1-5, transmitting sensing electrodes IE2-1 to IE2-4, and transmitting traces SL2-1 to SL2-4 connected to the transmitting sensing electrodes IE2-1 to IE2-4.

[0148] The receiving sensing electrodes IE1-1 to IE1-5 may intersect with the transmitting sensing electrodes IE2-1 to IE2-4. For example, the receiving sensing electrodes IE1-1 to IE1-5 may be arranged on a first direction DR1 and may extend on a second direction DR2. The transmitting sensing electrodes IE2-1 to IE2-4 may be arranged on the second direction DR2 and may extend on the first direction DR1.

[0149] The input sensor ISP can obtain coordinate information using a mutual capacitance method. A capacitance can be formed between the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4. This capacitance can be changed by an external input (e.g., a touch event). The sensitivity of the input sensor ISP can be determined based on the change in capacitance. For example, the sensitivity of the input sensor ISP can be increased by increasing the capacitance change due to an external input.

[0150] Each of the receiving sensing electrodes IE1-1 to IE1-5 may include a first sensor portion SSP1 and a first connection portion CP1 arranged in the effective area AA. Each of the transmitting sensing electrodes IE2-1 to IE2-4 may include a second sensor portion SSP2 and a second connection portion CP2 arranged in the effective area AA.

[0151] Figure 12 According to this embodiment, the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4 are shown to have specific shapes; however, this is merely an example, and the shapes of the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4 are not limited to this or thus restricted. According to embodiments conceived in this invention, the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4 may have a strip shape in which the sensor portion and the connecting portion are not distinguishable from each other. Figure 12 In the diagram, each of the first sensor portion SSP1 and the second sensor portion SSP2 is shown as having a rhomboid shape; however, the inventive concept is not limited thereto. For example, the first sensor portion SSP1 and the second sensor portion SSP2 may have polygonal shapes that are different from each other.

[0152] In a receiving sensing electrode, a first sensor portion SSP1 can be arranged on a second direction DR2, and in a transmitting sensing electrode, a second sensor portion SSP2 can be arranged on a first direction DR1. Each of the first connecting portions CP1 can connect to adjacent first sensor portions SSP1, and each of the second connecting portions CP2 can connect to adjacent second sensor portions SSP2.

[0153] The receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4 can each have a grid shape. Because the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4 each have a grid shape, the display panel DP can be reduced (see reference). Figure 4 The parasitic capacitance between the electrodes and the receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4.

[0154] The receiving sensing electrodes IE1-1 to IE1-5 and the transmitting sensing electrodes IE2-1 to IE2-4, each having a grid shape, may include, for example, materials such as silver, aluminum, copper, chromium, nickel, and titanium, which can be processed at low temperatures; however, the inventive concept is not limited thereto. Although the input sensor ISP is formed through a continuous process, damage to the organic light-emitting diode can be prevented.

[0155] Receiver traces SL1-1 to SL1-5 can be respectively connected to the first ends of the receive sensing electrodes IE1-1 to IE1-5. In this embodiment of the present invention, the input sensor ISP may further include receive traces respectively connected to the second ends of the receive sensing electrodes IE1-1 to IE1-5. Transmission traces SL2-1 to SL2-4 can be respectively connected to the first ends of the transmission sensing electrodes IE2-1 to IE2-4. In this embodiment of the present invention, the input sensor ISP may further include transmission traces connected to the second ends of the transmission sensing electrodes IE2-1 to IE2-4.

[0156] Receive traces SL1-1 to SL1-5 and transmit traces SL2-1 to SL2-4 can be disposed in the peripheral area NAA of the input sensor ISP. The input sensor ISP may include input pads I-PDs extending from the first ends of the receive traces SL1-1 to SL1-5 and the transmit traces SL2-1 to SL2-4, respectively, and disposed in the peripheral area NAA. The input pads I-PDs may include a first input pad IPD1 connected to the receive traces SL1-1 to SL1-5 and a second input pad IPD2 connected to the transmit traces SL2-1 to SL2-4.

[0157] Figure 13 This is a cross-sectional view illustrating an input sensor ISP according to an embodiment of the present invention. (Refer to...) Figure 12 and Figure 13 The input sensor ISP according to an 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 disposed on the encapsulation layer TFE. For example, the first sensing insulating layer IIL1 may be directly disposed on the encapsulation layer TFE. However, the present invention is not limited thereto. For example, the first sensing insulating layer IIL1 may be omitted.

[0158] Each of the first conductive layer ICL1 and the second conductive layer ICL2 may include multiple conductive patterns. The conductive patterns may include sensing electrodes IE1-1 to IE1-5 and IE2-1 to IE2-4 and signal lines SL1-1 to SL1-5 and SL2-1 to SL2-4 connected to the sensing electrodes IE1-1 to IE1-5 and IE2-1 to IE2-4.

[0159] Each of the first sensing insulating layer IIL1, the second sensing insulating layer IIL2, and the third sensing insulating layer IIL3 may comprise an inorganic material and / or an organic material. In this embodiment, each of the first sensing insulating layer IIL1 and the second sensing insulating layer IIL2 may be an inorganic layer. For example, the inorganic layer may comprise at least one of alumina, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide. The inorganic layer may have a thickness of about 1000 angstroms to about 4000 angstroms.

[0160] The third sensing insulating layer IIL3 can be an organic layer. For example, the organic layer may include at least one of the following: acrylic acid-based resin, methacrylic acid-based resin, polyisoprene-based resin, ethylene-based resin, epoxy-based resin, urethane-based resin, cellulose-based resin, siloxane-based resin, polyimide-based resin, polyamide-based resin, and dinoflagellated resin.

[0161] Figure 14 It is along the embodiments of the present invention. Figure 12 The section view taken by line IV-IV' is used to illustrate the display module DM. References will be omitted below. Figure 6 and Figure 8B The described component is the same as the component described in detail.

[0162] Reference Figure 12 and Figure 14 The second conductive layer ICL2 can be disposed on the second sensing insulating layer IIL2. As an example, the second conductive layer ICL2 may include receiving sensing electrodes IE1-1 to IE1-5 and transmitting sensing electrodes IE2-1 to IE2-4. As an example, Figure 14 This shows a portion of the transmission sensing electrodes IE2-3 (hereinafter referred to as the third transmission sensing electrodes) arranged in the third column, along... Figure 12 The cross section shown is taken by line IV-IV'.

[0163] The third transmission sensing electrode IE2-3 may include a first touch electrode SIE1 and a second touch electrode SIE2. The first touch electrode SIE1 may overlap with the non-light-emitting region NPXA, and the second touch electrode SIE2 may overlap with the light-emitting region PXA. However, the inventive concept is not limited thereto. For example, the second touch electrode SIE2 may overlap with both the non-light-emitting region NPXA and the light-emitting region PXA. In addition to the first touch electrode SIE1, the third transmission sensing electrode IE2-3 may also include a second touch electrode SIE2 disposed on the same layer as the first touch electrode SIE1, and therefore, the sensitivity of the input sensor ISP relative to external input can be improved.

[0164] Although the inventive concept has been described with reference to embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit and scope of the inventive concept.
