[0063] In the following description, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0064] Figure 1A This is a perspective view showing an electronic device ELD according to an embodiment of the present disclosure, and Figure 1B This is an exploded perspective view showing an electronic device ELD according to an embodiment of the present disclosure. Figure 2A and Figure 2B It is along the electronic device shown Figure 1B The cross-sectional view taken from line I-I'. Figure 2C and Figure 2D It is along the electronic device shown Figure 1B The cross-sectional view taken from line I-I'.

[0065] Reference Figure 1A and Figure 1B An electronic device (ELD) can be activated in response to an electrical signal. ELDs can be implemented in various ways. For example, ELDs can be used in electronic products such as smartphones, tablets, laptops, computer monitors, and smart TVs.

[0066] The electronic device ELD displays an image IM via a display surface IS that 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 corresponds to the front surface of the electronic device ELD. The image IM may be a video image and / or a still image.

[0067] According to the embodiment, the front (or upper) surface and the rear (or lower) surface of each component are defined relative to the direction of the displayed image IM. 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.

[0068] The spacing between the front and rear surfaces in the third direction DR3 corresponds to the thickness of the electronic device ELD in the third direction DR3. The directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 can be changed to align with... Figure 1A Other directions that are different from the directions specified in the text.

[0069] An electronic device ELD can sense external input applied to it. External input can be one or more of various types of input provided from outside the electronic device ELD. According to an embodiment, the electronic device ELD can sense a first input TC1 applied to it by a user US. The first input TC1 of the user US can be an input generated by the user US's finger and can include all inputs that cause changes in capacitance, such as inputs from using the user US's body. The first input TC1 can include input generated by a passive type of input device, such as a passive stylus. The electronic device ELD can sense the first input TC1 of the user US applied to the side or rear surface of the electronic device ELD depending on the structure of the electronic device ELD, and the invention is not necessarily limited to a particular embodiment.

[0070] Additionally, according to an embodiment, the electronic device ELD can sense a second input TC2 that is different from the first input TC1. The second input TC2 may include input generated by an input device AP (e.g., a stylus pen, an active stylus pen, a stylus stylus, an electronic pen, etc.). Hereinafter, the second input TC2 is described as an input signal provided by an active stylus pen.

[0071] The front surface of an electronic device (ELD) may include an image area IA and a border area BZA. The image area IA may be the area through which an image IM is displayed. The user can view the image IM through the image area IA. In an embodiment, the image area IA may have a quadrilateral shape with rounded vertices; however, this is merely an example and the invention is not necessarily limited to this particular example. The image area IA may have various shapes and the invention is not necessarily limited to an image area IA with a specific shape.

[0072] The border region BZA may be adjacent to the image region IA. The border region BZA may have a predetermined color. The border region BZA may at least partially surround the image region IA. Accordingly, the image region IA may have a shape defined by the border region BZA; however, this is merely an example and the invention is not necessarily limited to this particular example, and the border region BZA may be arranged to be adjacent only to one side of the image region IA, or the border region BZA may be omitted. According to embodiments of this disclosure, the electronic device ELD may be implemented in various different forms, and the invention is not necessarily limited to using any particular electronic device ELD.

[0073] like Figure 1B As shown, the electronic device ELD may include a display device DD, a window WM disposed on the display device DD, and a housing EDC. The display device DD may include a display panel DP and an input sensor ISP.

[0074] According to embodiments of this disclosure, the display panel DP can be a light-emitting display panel; however, the present invention is not limited to the use of light-emitting display panels. 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 and / or quantum rods. Hereinafter, organic light-emitting display panels are described as examples of display panel DPs.

[0075] The input sensor ISP can be arranged on the display panel DP and can obtain coordinate information of external inputs (e.g., first input TC1 and / or second input TC2). The input sensor ISP is described in detail below.

[0076] The display device DD may include a main circuit board MCB, a flexible circuit film FCB, and a driver chip DIC. One or more of the main circuit board MCB, flexible circuit film FCB, and driver chip DIC may be omitted. The main circuit board MCB may be connected to the flexible circuit film FCB, and the flexible circuit film FCB may be electrically connected to the display panel DP. The main circuit board MCB may include multiple driving elements. Driving elements may include circuitry portions that drive the display panel DP. The flexible circuit film FCB may be connected to the display panel DP to electrically connect the display panel DP to the main circuit board MCB. The driver chip DIC may be mounted on the flexible circuit film FCB.

[0077] The flexible circuit film FCB can be bent to allow the main circuit board MCB to face the rear surface of the display device DD. The main circuit board MCB can be electrically connected to other electronic modules of the electronic device ELD via connectors.

[0078] The driver chip (DIC) may include driving elements, such as data driving circuitry, for driving the pixels of the display panel (DP). In embodiments of this disclosure, a flexible circuit film (FCB) is shown; however, the invention is not limited to having only one flexible circuit film (FCB). For example, multiple flexible circuit films (FCBs) may be provided, and multiple flexible circuit films may be connected to the display panel (DP). Figure 1B The invention illustrates a structure in which a driver chip DIC is mounted on a flexible circuit film FCB; however, the invention is not limited to having a driver chip DIC mounted on a flexible circuit film FCB. For example, the driver chip DIC can be directly disposed on a display panel DP. A portion of the display panel DP can be bent, and the portion of the display panel DP in which the driver chip DIC is mounted can be arranged to face the rear surface of the display device DD.

[0079] The input sensor ISP can be electrically connected to the main circuit board MCB via an additional flexible circuit film; however, the invention is not limited to this specific example. The input sensor ISP can be electrically connected to the display panel DP, and the display panel DP can be electrically connected to the main circuit board MCB via a flexible circuit film FCB. The conductive structure for electrically connecting the input sensor ISP to the display panel DP can be applied to a display device DD.

[0080] The window WM may include a transparent material through which a visible image IM is transmitted. For example, the base layer of the window WM may include glass, sapphire, or plastic materials that transmit visible light. The window WM may have a single-layer structure. However, the invention is not limited to window WMs with a single-layer structure, and the window WM may include multiple layers (e.g., it may have a multi-layer structure).

[0081] The housing EDC can serve as a bottom protective structure for the electronic device ELD. The housing EDC can be attached to the window WM. The housing EDC absorbs impacts applied from the outside and prevents foreign objects and moisture from entering the display device DD, thus protecting the components installed within the housing EDC. The housing EDC can be formed from a single continuous structure or may comprise several structures connected to each other.

[0082] According to the implementation, the electronic device ELD may also include an electronic module, a power module, and a bracket. The electronic module includes various functional modules to drive the display device DD. The power module supplies the power required for the overall operation of the electronic device ELD. The bracket is connected to the display device DD and / or the housing EDC to separate the internal space of the electronic device ELD.

[0083] The above components can be bonded by the adhesive layer ADL (see reference). Figure 2AThe adhesive layers (ADLs) are interconnected. The ADL may include an optically clear adhesive film (OCA). However, the ADL is not limited to OCA, and may include conventional adhesives. For example, the ADL may include an optically clear resin (OCR) or a pressure-sensitive adhesive film (PSA).

[0084] An anti-reflective layer may also be disposed between the window WM and the display device DD. The anti-reflective layer reduces the reflectivity of external light incident on the window WM from above. According to embodiments of this disclosure, the anti-reflective layer may include a retarder and a polarizer. The retarder may be film-type or liquid crystal coating-type and may include a half-wave (λ / 2) retarder and / or a quarter-wave (λ / 4) retarder. The polarizer may be film-type or liquid crystal coating-type. A film-type polarizer may include a stretched synthetic resin film, and a liquid crystal coating-type polarizer may include liquid crystals arranged in a predetermined orientation. The retarder and polarizer may be implemented as a single polarizing film. In embodiments of this disclosure, the anti-reflective layer may be disposed directly on the input sensor ISP or the display panel DP. The retarder and / or polarizer may include a color filter that is internalized (e.g., as part of an element).

[0085] The display device DD can display an image in response to an electrical signal and can send / receive information about external input. The display device DD may include an active area AA and a peripheral area NAA. An image can be displayed through the active area AA, and external input can be sensed within the active area AA. The active area AA and the peripheral area NAA may respectively correspond to... Figure 1A The image region IA and the border region BZA are shown (and can be aligned with them). In the following description, the statement "region / part corresponds to another region / part" means "region / part overlaps with another region / part", but the statement is not limited to "region / part has the same area and / or the same shape as another region / part".

[0086] The peripheral region NAA may be defined as being adjacent to the effective region AA. For example, the peripheral region NAA may at least partially surround the effective region AA. However, this is merely an example, and the invention is not limited to this specific example, and the peripheral region NAA may be defined in various shapes. According to an embodiment, the effective region AA of the display device DD may correspond to at least a portion of the image region IA.

[0087] Reference Figure 2A The input sensor ISP can be directly disposed on the display panel DP. According to embodiments of this disclosure, 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 adhesive layer may not be disposed between the input sensor ISP and the display panel DP. However, as... Figure 2BAs shown, an adhesive layer (ADL) may be disposed between the input sensor ISP and the display panel DP. In this case, the input sensor ISP and the display panel DP may not be formed by a continuous process, and the input sensor ISP may be fixed to the upper surface of the display panel DP by the adhesive layer ADL after being formed by a separate process from the display panel DP.

[0088] like Figure 2A As shown, the window WM may include a light-blocking pattern WBM to define the border area BZA (see reference). Figure 1A The light-blocking pattern WBM can be a colored organic layer and can be formed on the lower surface of the base layer WM-BS by coating.

[0089] like Figure 2C As shown, the 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, a packaging substrate ES, and a sealant SM that bonds the base layer BL and the packaging substrate ES to each other.

[0090] The base layer BL may include at least one plastic film. The base layer BL may include a plastic substrate, a glass substrate, a metal substrate, or an organic / inorganic composite substrate. According to embodiments, the base layer BL may be a thin-film glass substrate having a thickness on the order of tens to hundreds of micrometers. The base layer BL may have a multilayer structure. For example, the base layer BL may include a multilayer structure of a polyimide layer / at least one inorganic layer / polyimide layer.

[0091] The circuit element layer DP-CL may include at least one insulating layer and circuit elements. The insulating layer may include at least one inorganic layer and at least one organic layer. The circuit elements may include signal lines and pixel driving circuitry. This will be described in detail below.

[0092] The display element layer of a DP-OLED may include at least a light-emitting element, such as an organic light-emitting diode. The display element layer of a DP-OLED may also include an organic layer, such as a pixel defining layer.

[0093] The encapsulation substrate ES can be spaced from the display element layer DP-OLED by a predetermined size gap GP (refer to...). Figure 4 The base layer BL and the encapsulation substrate ES may include a plastic substrate, a glass substrate, a metal substrate, or an organic / inorganic composite substrate. The sealant SM may include an organic adhesive or a glass frit. The gap GP may be filled with a predetermined material. For example, the gap GP may be filled with a desiccant or a resin material.

[0094] like Figure 2DAs shown, the 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 upper insulating layer TFL. The upper insulating layer TFL may include multiple thin layers.

[0131] Figure 5 This is a plan view showing an input sensor ISP according to an embodiment of the present disclosure. Figure 6 This is a schematic diagram illustrating the operation of the input sensor in the first mode. Figure 7A and Figure 7B This is a schematic diagram illustrating the operation of the input sensor in the second mode. In the following text, refer to... Figure 3A , Figure 5 , Figure 6 , Figure 7A and Figure 7B The input sensor ISP is described in detail.

[0132] Reference Figure 3A and Figure 5 The input sensor ISP can include a sensing area ISA and a non-sensing area NSA. The sensing area ISA can be activated in response to an electrical signal. The sensing area ISA and the non-sensing area NSA can respectively correspond to Figure 1B The effective area AA and the peripheral area NAA of the display device DD shown are illustrated.

[0133] The input sensor ISP may include first sensing electrodes SE1_1 to SE1_n (hereinafter referred to as first electrodes SE1_1 to SE1_n or first electrode SE1) and second sensing electrodes SE2_1 to SE2_m (hereinafter referred to as second electrodes SE2_1 to SE2_m or second electrode SE2). The first electrodes SE1_1 to SE1_n may be electrically insulated from and may intersect with the second electrodes SE2_1 to SE2_m. The area where the first electrodes SE1_1 to SE1_n intersect with the second electrodes SE2_1 to SE2_m may be defined as an electrode intersection region ECA. The area where the first electrodes SE1_1 to SE1_n do not intersect with the second electrodes SE2_1 to SE2_m may be defined as a non-intersection region N-CA. According to the embodiments, the first electrodes SE1_1 to SE1_n may be longer than the second electrodes SE2_1 to SE2_m, and the number of first electrodes SE1_1 to SE1_n may be less than the number of second electrodes SE2_1 to SE2_m. However, the present invention is not necessarily limited thereto or thereby restricted.

[0134] Each of the first electrodes SE1_1 to SE1_n may have a strip or band shape and may extend primarily in the first direction DR1. The first electrodes SE1_1 to SE1_n may be arranged in the second direction DR2 and may be spaced apart from each other. The first electrodes SE1_1 to SE1_n may have a substantially constant width W1 in the second direction DR2. The spacing between the first electrodes SE1_1 to SE1_n in the second direction DR2 may be constant.

[0135] Each of the second electrodes SE2_1 to SE2_m may have a strip or band shape and may extend in the second direction DR2. The second electrodes SE2_1 to SE2_m may be arranged in the first direction DR1 and may be spaced apart from each other. The second electrodes SE2_1 to SE2_m may have a substantially constant width W2 in the first direction DR1. The spacing between the second electrodes SE2_1 to SE2_m in the first direction DR1 may be constant.

[0136] The input sensor ISP obtains information about the first input TC1 (referencing) based on the capacitance change between the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m. Figure 3A In the first mode of information, or in the input sensor ISP obtaining information about the second input TC2 (refer to) based on the capacitance changes of each of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m,... Figure 3A In the second mode of the information, the ISP can be operated.

[0137] The input sensor ISP may further include a plurality of first sensing signal lines SL1_1 to SL1_n (hereinafter referred to as first signal lines SL1_1 to SL1_n or first signal lines SL1) and a plurality of second sensing signal lines SL2_1 to SL2_m (hereinafter referred to as second signal lines SL2_1 to SL2_m or second signal lines SL2). The first signal lines SL1_1 to SL1_n and the second signal lines SL2_1 to SL2_m may be arranged in the non-sensing region NSA. The first signal lines SL1_1 to SL1_n may be electrically connected to both sides of the first electrodes SE1_1 to SE1_n, respectively, and the second signal lines SL2_1 to SL2_m may be electrically connected to one side of the second electrodes SE2_1 to SE2_m. According to another embodiment of this disclosure, the first signal lines SL1_1 to SL1_n may be connected only to one side of the first electrodes SE1_1 to SE1_n.

[0138] The first electrodes SE1_1 to SE1_n can be electrically connected to the sensor controller 100 via first signal lines SL1_1 to SL1_n, and the second electrodes SE2_1 to SE2_m can be electrically connected to the sensor controller 100 via second signal lines SL2_1 to SL2_m. Each of the first signal lines SL1_1 to SL1_n and each of the second signal lines SL2_1 to SL2_m may include a line portion LP and a pad portion PP. The pad portion PP can be connected to... Figure 1B The flexible circuit film FCB shown is illustrated.

[0139] In a first mode, according to an embodiment of this disclosure, one of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m is operable as a transmitting electrode, and the other of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m is operable as a receiving electrode. Figure 6 In the diagram, the second electrodes SE2_1 and SE2_2 are shown as receiving electrodes. Figures 6 to 7B Two electrodes SE1_1 and SE1_2 from the first electrodes SE1_1 to SE1_n, and two electrodes SE2_1 and SE2_2 from the second electrodes SE2_1 to SE2_m are shown. In a first mode, the sensor controller 100 can sense changes in the mutual capacitance between the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m to sense external input.

[0140] In the first mode, the sensor controller 100 can apply drive signals TS1 and TS2 to the first electrodes SE1_1 and SE1_2. Drive signals TS1 and TS2 are shown as being applied to the first ends of the first electrodes SE1_1 and SE1_2; however, drive signals TS1 and TS2 can be applied substantially simultaneously to both ends of each of the first electrodes SE1_1 and SE1_2. In the first mode, the sensor controller 100 can receive sensing signals RS1 and RS2 from the second electrodes SE2_1 and SE2_2. Accordingly, the sensor controller 100 can compare the drive signals TS1 and TS2 with the sensing signals RS1 and RS2 corresponding to the drive signals TS1 and TS2, and can generate coordinate values ​​providing the position of the first input TC1 based on the changes between them.

[0141] Reference Figure 5 , Figure 7A and Figure 7B When the input device AP approaches the input sensor ISP, the input sensor ISP can enter a second mode to sense the second input TC2. The input device AP can communicate data with the sensor controller 100 through the input sensor ISP.

[0142] In the second mode, each of the first electrodes SE1_1 and SE1_2 and the second electrodes SE2_1 and SE2_2 can be used as a transmitting electrode to provide uplink signals TSa, TSb, TSc, and TSd from the sensor controller 100 to the input device AP. In the second mode, each of the first electrodes SE1_1 and SE1_2 and the second electrodes SE2_1 and SE2_2 can be used as a receiving electrode to provide downlink signals RSa, RSb, RSc, and RSd from the input device AP to the sensor controller 100. For example, all of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m can be used as either transmitting or receiving electrodes in the second mode.

[0143] When each of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m is configured as a strip, the change in mutual capacitance between the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m can remain substantially consistent even if the input device AP moves. Accordingly, although the second input TC2 moves, the movement of the second input TC2 can be accurately sensed in the second mode. For example, when writing or drawing using the input device AP, distortion of the second input TC2, which is provided linearly, due to changes in mutual capacitance can be prevented, and as a result, the linearity of the second input TC2 can be increased.

[0144] Figure 8A It is shown schematically. Figure 5 The diagram shows a plan view of the input sensor ISP. Figure 8B It is shown Figure 8A The image shows a magnified plan view of the four unit sensing areas UA. Figure 8C It is shown Figure 8B The image shows a magnified plan view of a single-unit sensing area UA. Figure 8D It is shown Figure 8C The enlarged plan view of the unit region SA shown. Figure 8E It is shown Figure 8C An enlarged plan view of the first intersection region CA1 shown. Figure 8F It is along Figure 8E The cross-sectional view taken from line II-II'. Figure 8G It is shown Figure 8C The enlarged plan view of the second intersection region CA2 shown. Figure 8H It is shown Figure 8C The enlarged plan view of the third intersection region CA3 shown. Figure 8I It is shown Figure 8C An enlarged plan view of the fourth intersection region CA4 shown. Figure 8J It is shown Figure 8C A magnified plan view of part of BB. Figure 8K It is shown Figure 5 The enlarged plan view of the pad area PA shown in the figure. Figure 8L It is along Figure 8K The cross-sectional view taken by line III-III' shown.

[0145] Reference Figure 8A The sensing area ISA comprises multiple unit sensing areas UA arranged in a matrix. For example... Figure 8A As shown, the entire sensing area ISA of the input sensor ISP is only arranged with unit sensing areas UA; however, the invention is not necessarily limited to this or by this limitation. In embodiments of this disclosure, the input sensor ISP may include a first sensing area and a second sensing area distinct from each other. The first sensing area may consist only of unit sensing areas UA, and the second sensing area, arranged outside the first sensing area, may include areas other than unit sensing areas UA, or may include unit sensing areas different from the unit sensing areas UA described below. For example, at least a portion of the sensing area ISA may be uniformly divided into multiple unit sensing areas UA. The multiple unit sensing areas UA may be arranged in rows and columns (e.g., in matrix form).

[0146] The unit sensing area UA may include at least Figure 5 The electrode crossover region ECA is shown in the figure. Based on the crossover ratio between the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m, the unit sensing region UA ​​may include only the electrode crossover region ECA, or it may also include the non-crossover region N-CA of the first electrodes SE1_1 to SE1_n and the second electrodes SE2_1 to SE2_m.

[0147] Reference Figure 8B The diagram illustrates two first electrodes SE1 and two second electrodes SE2 arranged in four unit sensing regions UA. According to an embodiment, the input sensor ISP may include a dummy electrode DE, which reduces the visibility difference between areas where the first electrodes SE1 and SE2 are not arranged and areas where the first electrodes SE1 and SE2 are arranged; however, the invention is not necessarily limited thereto. In embodiments of this disclosure, the dummy electrode DE may be omitted.

[0148] The width W1 of the first electrode SE1 in the electrode crossing region ECA is substantially the same as the width W1 of the first electrode SE1 in the non-crossing region N-CA, and the width W2 of the second electrode SE2 in the electrode crossing region ECA is substantially the same as the width W2 of the second electrode SE2 in the non-crossing region N-CA. Each of the first electrode SE1 and the second electrode SE2 may include a region with a relatively large width and a region with a relatively small width; however, the width of each of the first electrode SE1 and the second electrode SE2, measured from the same point in the electrode crossing region ECA and the non-crossing region N-CA, is substantially constant. Since the width of each of the first electrode SE1 and the second electrode SE2 is constant in the electrode crossing region ECA and the non-crossing region N-CA, the shape of the first electrode SE1 and the shape of the second electrode SE2 can be defined as a strip or a band shape. The width W1 of the first electrode SE1 is smaller than the width of the unit sensing region UA ​​in the second direction DR2, and the width W2 of the second electrode SE2 is smaller than the width of the unit sensing region UA ​​in the first direction DR1.

[0149] Reference Figure 8C The input sensor ISP has a grid shape. The input sensor ISP includes a plurality of first line elements LE1 extending substantially in a first extension direction EDR1 and a plurality of second line elements LE2 extending in a second extension direction EDR2 intersecting the first extension direction EDR1.

[0150] First line element LE1 and second line element LE2 define multiple intersection regions CA. Intersection region CA is the area where the first line element LE1 and second line element LE2 form either a hypothetical intersection or a real intersection. The difference between hypothetical and real intersections is described below. Open region OP is the area in the plane corresponding to the smallest polygonal shape defined by the first line element LE1 and second line element LE2, and the first line element LE1 and second line element LE2 are not arranged within the polygonal region. The polygonal shape corresponding to open region OP can be a rhombus shape (e.g., an elongated rhombus).

[0151] Because the area of ​​overlap between the first electrode SE1 and the second electrode SE2, which have a grid shape, and the second electrode CE of the display device DD is small, the base capacitance Cb (refer to...) Figure 4 Small. Correspondingly, drive signals TS1 and TS2 (refer to...) Figure 6 ) or uplink signals TSa, TSb, TSC, and TSd (refer to Figure 7A The signal transmission is fast because the RC delay of the signal is small. In this case, the first line element LE1 and the second line element LE2 may include metallic material to reduce the resistance of the first electrode SE1 and the second electrode SE2.

[0152] In the first wire element LE1 and the second wire element LE2, the first set of elements LE-G1 is electrically connected to each other to define the first electrode SE1, and in the first wire element LE1 and the second wire element LE2, the second set of elements LE-G2 is electrically connected to each other to define the second electrode SE2.

[0153] The first wire element LE1 of the first group of elements LE-G1 defines the first electrode line E1-L1 of the first electrode SE1. The second wire element LE2 of the first group of elements LE-G1 defines the second electrode line E1-L2 of the first electrode SE1. The first wire element LE1 of the second group of elements LE-G2 defines the first electrode line E2-L1 of the second electrode SE2. The second wire element LE2 of the second group of elements LE-G2 defines the second electrode line E2-L2 of the second electrode SE2.

[0154] The first electrode line E1-L1 of the first electrode SE1 can be substantially parallel to the first electrode line E2-L1 of the second electrode SE2, and the second electrode line E1-L2 of the first electrode SE1 can be substantially parallel to the second electrode line E2-L2 of the second electrode SE2. The first electrode line E2-L1 of the second electrode SE2 can be arranged between the two closest first electrode lines E1-L1 of the first electrode SE1 in the second extension direction EDR2. The first electrode line E2-L1 of the second electrode SE2 can be arranged to be closer to one of the two first electrode lines E1-L1 of the first electrode SE1 than the other of the two first electrode lines E1-L1 of the first electrode SE1. An open region OP can be arranged between the relatively close first electrode lines E2-L1 of the second electrode SE2 and the first electrode lines E1-L1 of the first electrode SE1, and two open regions OP can be arranged between the more distant first electrode lines E2-L1 of the second electrode SE2 and the first electrode lines E1-L1 of the first electrode SE1. To aid understanding, in Figure 8C The three open areas (OP) are indicated by shadows.

[0155] In the first wire element LE1 and the second wire element LE2, a third set of elements LE-G3 may define a dummy electrode DE that is insulated from the first electrode SE1 and the second electrode SE2. After the first wire element LE1 and the second wire element LE2 are fully connected, the first wire element LE1 and the second wire element LE2 are disconnected according to a predetermined rule, so that the three sets of elements LE-G1, LE-G2 and LE-G3 are distinguished from each other, thereby insulating the first electrode SE1, the second electrode SE2 and the dummy electrode DE from each other. The disconnected area described above corresponds to the imaginary crossover point described below.

[0156] exist Figure 8CIn this diagram, the three groups of elements LE-G1, LE-G2, and LE-G3 are shown differently to distinguish them from each other; however, the first group of elements LE-G1, the second group of elements LE-G2, and the third group of elements LE-G3 may have substantially the same linewidth, thickness, and material as each other. The first group of elements LE-G1, the second group of elements LE-G2, and the third group of elements LE-G3 may be distinguished from each other by electrical connections.

[0157] like Figure 8C As shown, the unit sensing area UA comprises multiple unit areas SA. For example, the unit sensing area UA can be uniformly divided into multiple unit areas SA. The multiple unit areas SA can be arranged into multiple rows and multiple columns. Figure 8C Six cell regions SA are shown as representative examples. Each cell region SA includes a cross region CA.

[0158] Reference Figure 8D A detailed description of the cell region SA is provided. (Refer to...) Figure 8D At the center of the unit region SA, there is a cross region CA-C (hereinafter referred to as the central cross region). The unit region SA is defined by four cross regions CA-C1 to CA-C4 that are closest to the central cross region CA-C.

[0159] Figure 8D The display panel DP (reference) is shown. Figure 4 The launch areas are PXA-R, PXA-B, PXA-G1, and PXA-G2. Figure 8D In the illustration, four types of emitting regions PXA-R, PXA-B, PXA-G1, and PXA-G2, which have different shapes from each other, are shown as representative examples; however, the invention is not necessarily limited thereto. In some embodiments, two of the four types of emitting regions PXA-R, PXA-B, PXA-G1, and PXA-G2 emit light of the same color; however, the invention is not necessarily limited thereto.

[0160] The first emission region PXA-R is the emission region of the first color pixel, the second emission region PXA-B is the emission region of the second color pixel, and the third emission region PXA-G1 and the fourth emission region PXA-G2 are the emission regions of the third color pixel. The first color light is red light, the second color light is blue light, and the third color light is green light, and the first, second, and third color lights can be changed to other three primary colors. According to embodiments of this disclosure, the third emission region PXA-G1 and the fourth emission region PXA-G2 may have the same shape as each other.

[0161] The display panel (DP) may include multiple pixel units (PUAs). Each PUA may include multiple emission regions, and the PUA may include the same number of emission regions. PUAs may have the same arrangement of emission regions. PUAs may be grouped into two groups. PUAs included in the same group have the same arrangement of emission regions, and PUAs included in different groups may have different arrangements of emission regions. Although the arrangements of emission regions in the two groups of PUAs are different from each other, the corresponding emission regions are provided to the two groups of PUAs respectively.

[0162] When viewed in a plane, the unit pixel area (PUA) can have the same size. The unit pixel area (PUA) is defined by dividing the display panel (DP) into identical regions, each comprising the same number of emission areas.

[0163] The unit pixel region PUA may have a quadrilateral shape including a first diagonal CL1 and a second diagonal CL2 intersecting the first diagonal CL1. The unit pixel region PUA may have a square shape or a rectangular shape.

[0164] Each unit pixel region PUA includes a first emitting region PXA-R, a second emitting region PXA-B, a third emitting region PXA-G1, and a fourth emitting region PXA-G2. The first emitting region PXA-R and the second emitting region PXA-B face each other in a first direction DR1, and the third emitting region PXA-G1 and the fourth emitting region PXA-G2 face each other in a second direction DR2. A first diagonal line CL1 passing through the first emitting region PXA-R and the second emitting region PXA-B is substantially parallel to the first direction DR1, and a second diagonal line CL2 passing through the third emitting region PXA-G1 and the fourth emitting region PXA-G2 is substantially parallel to the second direction DR2. Accordingly, the angle between the first diagonal line CL1 and the second diagonal line CL2 can be approximately 90 degrees. This angle is referred to as the first angle θ1.

[0165] In one embodiment, the first angle θ1 may be approximately 90 degrees. In another embodiment, all angles between the first diagonal CL1 and the second diagonal CL2 may be approximately 90 degrees. According to embodiments of this disclosure, the angles defined by the first diagonal CL1 and the second diagonal CL2 may include acute and obtuse angles. This disclosure describes a unit pixel region PUA comprising four types of emission regions PXA-R, PXA-B, PXA-G1, and PXA-G2; however, the invention is not necessarily limited thereto. The arrangement of the diagonals and the first angle θ1 may vary depending on the arrangement and number of emission regions in the unit pixel region PUA.

[0166] The first line element LE1 and the second line element LE2, having a straight shape and arranged in the unit region SA, may overlap with some of the first emission regions PXA-R, the second emission region PXA-B, the third emission region PXA-G1, and the fourth emission region PXA-G2. According to an embodiment of this disclosure, the first line element LE1 and the second line element LE2 arranged in the unit region SA may be arranged only in the non-emission region NPXA while maintaining their extension directions EDR1 and EDR2, and in this case, the first line element LE1 and the second line element LE2 may include multiple curved regions.

[0167] The first line element LE1 and the second line element LE2, arranged in the unit region SA, define an angle in the intersection region CA. This angle is described as a second angle θ2. The second angle θ2 is selected to correspond to the first angle θ1. For example, when the two diagonals define acute and obtuse angles, and the first line element LE1 and the second line element LE2 define acute and obtuse angles, both the first angle θ1 and the second angle θ2 can be acute or obtuse.

[0168] The first angle θ1 and the corresponding second angle θ2 have different values. The first angle θ1 is an index indicating the period of repeated placement of the unit pixel region PUA, and the second angle θ2 is an index indicating the period of repeated placement of the unit region SA. When the first angle θ1 and the second angle θ2 are the same, the period of the unit pixel region PUA overlaps with the period of the unit region SA, which leads to moiré effect. According to the embodiment, since the first angle θ1 and the second angle θ2 are different, the overlap between the period of the unit pixel region PUA and the period of the unit region SA can be reduced, and thus the moiré effect can be prevented.

[0169] Refer again Figure 8C Multiple unit regions SA can be arranged in a matrix of N multiplied by M within a single unit sensing region UA. In the implementation, each of "N" and "M" can be a multiple of 3, and "N" and "M" can be different natural numbers. "N" can be greater than "M", "N" can be 18, and "M" can be 12. As the values ​​of "N" and "M" increase, the size of the unit region SA decreases, and the number of unit regions SA increases.

[0170] The vertical width W10 of the unit region SA (i.e., the width in the second direction DR2) can be smaller than the horizontal width W20 of the unit region SA (i.e., the width in the first direction DR1). The ratio of the vertical width W10 to the horizontal width W20 of the unit region SA can be set to minimize moiré effects. The ratio of the vertical width W10 to the horizontal width W20 of the unit region SA can be determined by the unit pixel region PUA applied to the product, and it should not be limited to a specific value.

[0171] Reference Figure 8C and Figures 8E to 8I The intersection region CA is described in detail. The intersection region CA may include a first intersection region CA1, a second intersection region CA2, a third intersection region CA3, and a fourth intersection region CA4.

[0172] Reference Figure 8C and Figure 8E One of the first line elements LE1 and the second line element LE2 of the first group of elements LE-G1 may cross with another element of the first line element LE1 and the second line element LE2 of the second group of elements LE-G2. Figure 8E The first intersection region CA1 is shown, defining the imaginary intersection point by the second line element LE2 of the first group of elements LE-G1 and the first line element LE1 of the second group of elements LE-G2. Figure 8E The diagram illustrates a first intersection region CA1 where the second wire element LE2 of the first group of elements LE-G1 is disconnected and the first wire element LE1 of the second group of elements LE-G2 passes through the disconnected area of ​​the second wire element LE2. However, the invention is not necessarily limited thereto or thereby restricted. According to an embodiment of this disclosure, the first wire element LE1 of the second group of elements LE-G2 may be disconnected in the first intersection region CA1.

[0173] Reference Figure 8F After being formed by a continuous process, the first line element LE1 and the second line element LE2 can be directly disposed on the upper surface of the packaging substrate ES without an adhesive layer. The first sensor insulating layer IIL1 at least partially covers the first line element LE1 and the second line element LE2. A bridging pattern BRP is disposed on the first sensor insulating layer IIL1 and connects the disconnected areas of the second line element LE2 of the first group of elements LE-G1 through contact holes CH20. According to another embodiment of this disclosure, the bridging pattern BRP can be disposed on the upper surface of the packaging substrate ES, and the first line element LE1 and the second line element LE2 can be disposed on the first sensor insulating layer IIL1.

[0174] Reference Figure 8C and Figure 8G One of the first line elements LE1 and the second line element LE2 of the first group of elements LE-G1 may cross with another element of the first line element LE1 and the second line element LE2 of the second group of elements LE-G2. Figure 8G The diagram shows a second intersection region CA2 defined by the second line element LE2 of the first group of elements LE-G1 and the first line element LE1 of the second group of elements LE-G2, indicating an imaginary intersection point. The first line element LE1 of the second group of elements LE-G2 is disconnected. Unlike the first intersection region CA1, the bridging pattern BRP is not arranged in the second intersection region CA2.

[0175] The resistance of the first sensing electrode SE1 and / or the second sensing electrode SE2 and / or the intensity of the current flowing through the first sensing electrode SE1 and / or the second sensing electrode SE2 can be controlled by adjusting the number of bridging patterns BRP. For example, as Figure 9B As shown, the second cross region CA2 can be arranged in a region that has a low impact on the flow of current. (Refer to...) Figure 9B Since the current flows in the first direction DR1 of the first electrode SE1 and the second cross region CA2 induces the current to flow in the second direction DR2, it has a low influence on the current flow. Accordingly, the bridging pattern BRP connecting the first line element LE1 or the second line element LE2 of the first electrode SE1 can be omitted.

[0176] Reference Figure 8C and Figure 8H One of the first line element LE1 of the first group of elements LE-G1, the second line element LE2 of the first group of elements LE-G1, the first line element LE1 of the second group of elements LE-G2, and the second line element LE2 of the second group of elements LE-G2 may cross with another element of the first line element LE1 of the third group of elements LE-G3 and the second line element LE2 of the third group of elements LE-G3. Figure 8H The diagram illustrates a third intersection region CA3 defining the imaginary intersection point of the second line element LE2 of the first group of elements LE-G1 and the first line element LE1 of the third group of elements LE-G3. Similar to the second intersection region CA2, the bridging pattern BRP may not be arranged in the third intersection region CA3. An example shows a disconnected second line element LE2 of the first group of elements LE-G1; however, the invention is not necessarily limited thereto. The first line element LE1 of the third group of elements LE-G3 may be disconnected.

[0177] The third cross region CA3 defines the boundaries of the first electrode SE1, the second electrode SE2, and the dummy electrode DE. Since one of the first line elements LE1 and LE2 of the first electrode SE1, the second electrode SE2, and the dummy electrode DE is separated from the other of the first line elements LE1 and LE2 of the first electrode SE1, the second electrode SE2, and the dummy electrode DE, the first electrode SE1, the second electrode SE2, and the dummy electrode DE are electrically insulated from each other.

[0178] Reference Figure 8C and Figure 8IThe first line element LE1 and the second line element LE2 of the first group of elements LE-G1 can be integrally arranged with each other (e.g., arranged as a continuous structure) and can cross each other. The first line element LE1 and the second line element LE2 of the second group of elements LE-G2 can be integrally arranged with each other and can cross each other. The first line element LE1 and the second line element LE2 of the third group of elements LE-G3 can be integrally arranged with each other and can cross each other. Figure 8I The first line element LE1 and the second line element LE2 of the first group of elements LE-G1 are shown to define the fourth intersection region CA4, which defines the actual intersection point. The bridging pattern BRP is not required for the fourth intersection region CA4 and can therefore be omitted from it.

[0179] Reference Figure 8J The open region defined by the first wire element LE1 and the second wire element LE2 adjacent to the first intersection region CA1 may have an open rhombus shape. The open region defined by the first wire element LE1 and the second wire element LE2 adjacent to the second intersection region CA2 may have an open rhombus shape. The open region defined by the first wire element LE1 and the second wire element LE2 adjacent to the third intersection region CA3 may have an open rhombus shape. The open rhombus shapes connect adjacent open regions. The open region defined by the first wire element LE1 and the second wire element LE2 adjacent to the fourth intersection region CA4 may have an open rhombus shape. The open region defined by the first wire element LE1 and the second wire element LE2 adjacent to the fourth intersection region CA4 arranged in the dummy electrode DE may have a closed rhombus shape.

[0180] like Figure 5 and Figure 8K As shown, the first signal line SL1 and the second signal line SL2 may include a line portion LP and a pad portion PP. The pad portion PP may include a first layer PP1 and a second layer PP2. The line portion LP may be integrally disposed with the first layer PP1 of the pad portion PP. The line portion LP and the first layer PP1 of the pad portion PP may be formed by the same process, may include the same material, and may have the same stacking structure. According to an embodiment, the line portion LP and the pad portion PP may have different linewidths from each other; however, the line portion LP and the pad portion PP may have the same linewidth.

[0181] like Figure 8LAs shown, the first layer PP1 of the pad portion PP is disposed between the upper surface of the package substrate ES and the first sensor insulating layer IIL1. The second layer PP2 of the pad portion PP is disposed on the first sensor insulating layer IIL1 and connected to the first layer PP1 of the pad portion PP via a contact hole CH20 defined by the first sensor insulating layer IIL1. The second sensor insulating layer IIL2 is provided with at least the second layer PP2 of the pad portion PP through its exposed contact hole CNT. The second layer PP2 of at least the pad portion PP can be electrically connected to the pads of the flexible circuit board via an anisotropic conductive film or solder balls. The second layer PP2 of the pad portion PP is connected to the bridging pattern BRP (see reference). Figure 8F The same process can be used to form the same materials, and the same stacking structure can be used. The second layer PP2 of the pad portion PP and the bridging pattern BRP can include transparent conductive oxides.

[0182] Figure 9A and Figure 9B This is an enlarged plan view showing the unit sensing region UA ​​according to an embodiment of the present disclosure. In the following, with reference to... Figures 8A to 8L The extent to which detailed descriptions of the elements are omitted may be assumed that these elements are at least similar to their counterparts described elsewhere in this disclosure.

[0183] Reference Figure 9A The width of the unit sensing region UA ​​in the first direction DR1 is substantially the same as the width W2 of the second electrode SE2 in the first direction DR1. The width of the unit sensing region UA ​​in the second direction DR2 is substantially the same as the width W1 of the first electrode SE1 in the second direction DR2. The unit sensing region UA ​​is defined as being similar to the reference... Figure 8B The described electrode cross region ECA is essentially the same.

[0184] The non-intersecting regions N-CA are arranged to have predetermined dimensions. Figure 8B Unlike other electrodes, the boundary between adjacent first electrodes SE1 and the boundary between adjacent second electrodes SE2 are defined by the disconnection of the first line element LE1 and the second line element LE2.

[0185] In this case, within the unit sensing region UA, the length of the longest electrode line among the first electrode lines E1-L1 of the first electrode SE1 is substantially the same as the length of the longest electrode line among the first electrode lines E2-L1 of the second electrode SE2. Similarly, the length of the longest electrode line among the second electrode lines E1-L2 of the first electrode SE1 is substantially the same as the length of the longest electrode line among the second electrode lines E2-L2 of the second electrode SE2.

[0186] Reference Figure 9B When with Figure 9AWhen comparing the unit sensing region UA ​​shown, the dimensions of the first line element LE1 and the second line element LE2 of the first electrode SE1 decrease, and the dimensions of the first line element LE1 and the second line element LE2 of the dummy electrode DE increase. Accordingly, in the unit sensing region UA, the longest electrode line among the first electrode lines E1-L1 of the first electrode SE1 is shorter than the longest electrode line among the first electrode lines E2-L1 of the second electrode SE2. Similarly, the longest electrode line among the second electrode lines E1-L2 of the first electrode SE1 is shorter than the longest electrode line among the second electrode lines E2-L2 of the second electrode SE2.

[0187] When with Figure 9A When comparing the unit sensing area UA shown, the width W2 of the second electrode SE2 decreases. The dimensions of the first line element LE1 and the second line element LE2 of the second electrode SE2 decrease, while the dimensions of the first line element LE1 and the second line element LE2 of the dummy electrode DE increase. The decrease in the size of the second electrode SE2 is less than the decrease in the size of the first electrode SE1.

[0188] The polygonal shape defined by the first electrode line E1-L1 and the second electrode line E1-L2 of the first electrode SE1 may have a larger area than the polygonal shape defined by the first electrode line E2-L1 and the second electrode line E2-L2 of the second electrode SE2. Figure 9B The hexagonal shape defined in the first electrode SE1 and the quadrilateral shape defined in the second electrode SE2 are shown. Figure 9B In the image, one of the multiple hexagonal shapes is shown in shaded areas, and one of the multiple quadrilateral shapes is shown in shaded areas.

[0189] Figure 10A and Figure 10B This is an enlarged plan view showing the unit region SA according to an embodiment of the present disclosure. In the following, with reference to... Figure 8C and Figure 8D The extent to which detailed descriptions of the elements are omitted may be assumed that these elements are at least similar to their counterparts described elsewhere in this disclosure.

[0190] Reference Figure 10AEach unit pixel region PUA includes a first emitting region PXA-R, a second emitting region PXA-B, and a third emitting region PXA-G. In each unit pixel region PUA, the third emitting region PXA-G is arranged between the first emitting region PXA-R and the second emitting region PXA-B; however, the arrangement of the emitting regions can be changed. Each of the first emitting region PXA-R, the second emitting region PXA-B, and the third emitting region PXA-G may extend in a second direction DR2. The first emitting region PXA-R, the second emitting region PXA-B, and the third emitting region PXA-G may have substantially the same size as each other.

[0191] The unit pixel region PUA may have a first angle θ10 defined by a first diagonal CL1 and a second diagonal CL2. The first angle θ10 may be an acute angle and may have a value different from that of the second angle θ2.

[0192] Reference Figure 10B Each pixel region PUA includes a first emitting region PXA-R, a second emitting region PXA-B, and a third emitting region PXA-G. The second emitting region PXA-B has the largest size. The first emitting region PXA-R and the third emitting region PXA-G are arranged to the left of the second emitting region PXA-B. The first emitting region PXA-R and the third emitting region PXA-G may have substantially the same size as each other.

[0193] The unit pixel region PUA may have a first angle θ100 defined by a first diagonal CL1 and a second diagonal CL2. The first angle θ100 may have a value different from that of the second angle θ2.
