[0002] This application claims priority from Korean Patent Application No. 10-2020-0018291 filed on February 14, 2020, in the Korean Intellectual Property Office (KIPO), the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present invention relates to an antenna-insertion electrode structure and an image display device including the same. More particularly, the present invention relates to an antenna-insertion electrode structure including an antenna pattern and a sensing electrode and an image display device including the same. Background Art

[0004] Recently, electronic devices capable of inputting a user's direction by selecting an instruction displayed on an image display device with a human hand or an object are implemented in various forms such as smartphones, tablet computers, etc. through a combination of an image display device and a touch sensor.

[0005] In addition, the image display device is combined with a communication device such as a smartphone. For example, an antenna for realizing high-frequency or ultra-high-frequency communication in the 3G to 5G or higher frequency band can be applied to the image display device.

[0006] As described above, when a touch sensor and an antenna are applied to a single image display device, a design structure is required to fit multiple electrodes into a limited space. For example, if the touch sensing electrodes and the antenna's radiation electrode are formed together, it can be difficult to easily form the radiation electrode in the desired shape to achieve predetermined radiation characteristics.

[0007] Furthermore, when the touch sensing electrodes overlap with the pixel structure of the image display device, the image quality of the image display device may be degraded due to optical phenomena such as a moire phenomenon.

[0008] For example, as disclosed in Korean Patent Application Publication No. 2014-0092366, a touch screen panel has recently been developed in which a touch sensor is combined with various image display devices. Korean Patent Application Publication No. 2013-0095451 discloses an antenna integrated into a display panel. Summary of the Invention

[0030] In addition, the two different types of mesh structures can be mixed, so that the irregularity of the entire mesh structure can be increased. Therefore, the moiré phenomenon caused by the overlap between the antenna-interposed electrode structure and the pixels of the display panel can be prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] According to an exemplary embodiment of the present invention, there is provided an antenna insertion type electrode structure including an antenna pattern and a sensing electrode in the same plane, and an image display device including the antenna insertion type electrode structure.

[0039] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, those skilled in the art will appreciate that such embodiments described with reference to the accompanying drawings are provided for further understanding of the spirit of the present invention and do not limit the subject matter disclosed in the detailed description and the appended claims.

[0040] The terms “first direction”, “second direction”, “third direction”, “fourth direction”, “column direction” and “row direction” used herein are not intended to indicate absolute specific directions, but are used to relatively distinguish different directions from each other.

[0041] Figure 1 is a schematic top plan view illustrating an antenna insertion type electrode structure according to an exemplary embodiment. Figure 2 : is a schematic cross-sectional view showing the configuration of a sensing electrode in an antenna insertion type electrode structure according to an exemplary embodiment. Specifically, Figure 2 In the thickness direction along Figure 1 A cross-sectional view taken along line II'.

[0042] exist Figure 1 and Figure 2 In order to facilitate the description of the arrangement of the electrodes of the antenna insertion type electrode structure, each electrode is shown as a solid pattern. However, as will be referred to later Figures 3 to 5 As described, each electrode may have a mesh structure.

[0043] Reference Figure 1 and Figure 2 The antenna insertion electrode structure may include a substrate layer 100 and sensing electrodes 110 and 130 and an antenna pattern 170 arranged on the substrate layer 100.

[0044] The substrate layer 100 or the antenna-interposition electrode structure may include a touch sensing region TR and a touch sensing antenna region TAR.

[0045] The touch sensing region TR may include a central portion of the substrate layer 100 and may substantially function as an active region of a touch sensor through which a user's touch input is sensed.

[0046] The touch sensing antenna region TAR may be a region in which an antenna pattern 170 for implementing high-frequency or ultra-high-frequency communication (e.g., 3G, 4G, 5G communication, or higher) may be included. In an exemplary embodiment, some sensing electrodes 110 and 130 of the touch sensor may be distributed in the touch sensing antenna region TAR along with the antenna pattern 170.

[0047] like Figure 1 As shown, the touch sensing antenna area TAR may be allocated to an end portion or a side portion of the substrate layer 100 adjacent to the touch sensing area TR.

[0048] The first sensing electrode 110 and the second sensing electrode 130 may be arranged on the touch sensing region TR and the touch sensing antenna region TAR of the substrate layer 100. In an exemplary embodiment, touch sensing may be achieved through mutual capacitance between the first sensing electrode 110 and the second sensing electrode 130.

[0049] The substrate layer 100 may include a supporting layer or a film-type substrate for forming the sensing electrodes 110 and 130 and the antenna pattern 170. For example, the substrate layer 100 may include a film material commonly used for touch sensors without particular limitation, and may include, for example, glass, polymers, and / or inorganic insulating materials. Examples of polymers may include cycloolefin polymers (COP), polyethylene terephthalate (PET), polyacrylates (PAR), polyetherimides (PEI), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyallyls, polyimides (PI), cellulose acetate propionate (CAP), polyethersulfone (PES), cellulose triacetate (TAC), polycarbonate (PC), cycloolefin copolymers (COC), polymethyl methacrylate (PMMA), and the like. Examples of inorganic insulating materials include silicon oxide, silicon nitride, silicon oxynitride, and metal oxides.

[0050] In some embodiments, a layer or film member of an image display device to which an antenna-interposed electrode structure is applied may be used as the substrate layer 100. For example, an encapsulation layer or a passivation layer included in a display panel may be used as the substrate layer 100.

[0051] The substrate layer 100 may serve as a dielectric layer of the antenna pattern 170. Preferably, the dielectric constant of the substrate layer 100 may be adjusted within a range of approximately 1.5 to 12. When the dielectric constant exceeds approximately 12, the driving frequency may be excessively reduced, and an antenna driven at a desired high frequency or ultra-high frequency band may not be realized.

[0052] The first sensing electrodes 110 may be arranged along a column direction (e.g., a Y direction or a length direction). The first sensing electrodes 110 adjacent to each other in the column direction may be connected to each other by a connecting portion 115. The first sensing electrodes 110 and the connecting portion 115 may be integrally connected to each other to be substantially provided as a single member. In this case, the first sensing electrodes 110 and the connecting portion 115 may be formed using the same conductive layer by the same patterning process (e.g., a mesh structure) and may be located in the same layer or at the same level.

[0053] Therefore, a first sensing electrode column extending in the first direction may be defined, and a plurality of first sensing electrode columns may be arranged along the row direction.

[0054] Second sensing electrodes 130 may be arranged along a row direction (eg, an X direction or a width direction), each having an independent island pattern shape, and adjacent second sensing electrodes 130 in the row direction may be electrically connected to each other via bridge electrodes 135 .

[0055] Therefore, a second sensing electrode row extending in the row direction may be defined, and a plurality of second sensing electrode rows may be arranged along the column direction.

[0056] Figure 1 An example is shown in which the second sensing electrode rows include the bridging electrodes 135 and the first sensing electrode columns include the connecting portions 115. However, the first sensing electrode columns may be defined by the bridging electrodes, and the second sensing electrode rows may be defined by the connecting portions.

[0057] The sensing electrodes 110 and 130 and / or the bridge electrode 135 may include silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W), niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), molybdenum (Mo), tin (Sn), calcium (Ca), or an alloy containing at least one metal (e.g., silver-palladium-copper (APC) or a copper alloy (e.g., copper calcium (CuCa)). These may be used alone or in combination.

[0058] The sensing electrodes 110 and 130 and / or the bridge electrode 135 may include a transparent conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium zinc tin oxide (IZTO), cadmium tin oxide (CTO), etc.

[0059] In some embodiments, the sensing electrodes 110 and 130 and / or the bridging electrode 135 may have a multilayer structure including a metal or alloy layer and a transparent metal oxide layer. For example, the sensing electrodes 110 and 130 and / or the bridging electrode 135 may include a double-layer structure of a transparent conductive oxide layer and a metal layer, or a triple-layer structure of a first transparent conductive oxide layer, a metal layer, and a second transparent conductive oxide layer.

[0060] In this case, the metal layer can improve flexibility, reduce resistance and increase signal transmission speed, and improve corrosion resistance and transparency by using the transparent conductive oxide layer.

[0061] like Figure 2 As shown, insulating layer 140 may be formed on substrate layer 100 to at least partially cover sensing electrodes 110 and 130 and connection portion 115. Bridge electrode 135 may be provided on insulating layer 140 to electrically connect adjacent second sensing electrodes 130 to each other through, for example, contact holes 145 formed in insulating layer 140.

[0062] A passivation layer 150 for protecting the touch sensor may be formed on the insulating layer 140 and the bridge electrode 135 .

[0063] The insulating layer 140 and the passivation layer 150 may include an inorganic insulating material such as silicon oxide or silicon nitride, and / or an organic insulating material such as acrylic resin or siloxane resin.

[0064] In some embodiments, the sensing electrodes 110 and 130 and the bridging electrode 135 may be arranged in a bottom bridge structure. In this case, the bridging electrode 135 may be disposed below the sensing electrodes 110 and 130. For example, the bridging electrode 135 may include a low-resistance metal and may be disposed away from a visible surface (e.g., the top surface of the passivation layer 150) to reduce channel resistance and visual identification of the electrodes by light.

[0065] The sensing electrodes 110 and 130 and the antenna pattern 170 may be arranged together on the touch sensing antenna region TAR of the substrate layer 100. In an exemplary embodiment, the sensing electrodes 110 and 130 and the antenna pattern 170 may be located at the same layer or level.

[0066] Antenna pattern 170 may include radiation pattern 160, transmission line 162, and signal pad 165. The boundary of radiation pattern 160 may have a polygonal shape such as a rhombus or a diamond. Transmission line 162 may extend from one end of radiation pattern 160. Signal pad 165 may be electrically connected to the end portion of transmission line 162.

[0067] Antenna pattern 170 may include a conductive material substantially the same as or similar to sensing electrodes 110 and 130. For example, antenna pattern 170 may include the above-mentioned metal or alloy or transparent conductive oxide, and may have a multi-layer structure of a metal layer and a transparent conductive oxide layer.

[0068] As referenced later Figure 4 and Figure 5 As described above, the radiation pattern 160 and the transmission line 162 may be formed of a mesh structure including a plurality of electrode lines intersecting each other. In an embodiment, the radiation pattern 160 and the transmission line 162 may be formed as a substantially single member formed of the mesh structure.

[0069] The signal pads 165 can be formed as a solid pattern including the above-mentioned metal or alloy to reduce the feed resistance. In one embodiment, a ground pad (not shown) can also be provided around each signal pad 165. The signal pads 165 can be electrically connected to the antenna driver IC chip through a conductive intermediate structure (e.g., a flexible printed circuit board (FPCB) and an anisotropic conductive film (ACF)).

[0070] The radiation pattern 160 may have a shape inserted between the sensing electrodes 110 and 130 in the touch sensing antenna region TAR. Therefore, the sensing electrodes 110 and 130 adjacent to the radiation pattern 160 may have a shape partially cut or removed from the shape of the sensing electrodes 110 and 130 in the touch sensing region TR by the radiation pattern 160.

[0071] As described above, the radiation pattern 160 of the antenna pattern 170 may be disposed on the same plane or at the same level as the sensing electrodes 110 and 130, and may be disposed between the sensing electrodes 110 and 130. Thus, the antenna pattern 170 may be integrated with the touch sensor, such that touch sensing and antenna radiation may be simultaneously implemented from one electrode layer.

[0072] Figures 3 to 5 is a partially enlarged top view showing the mesh structure included in the sensing electrode and the radiation pattern. For example, Figures 3 to 5 is a partially enlarged top plan view showing a region of a sensing electrode and a region of a radiation pattern in the touch sensing antenna region TAR.

[0073] Specifically, Figure 3 is a schematic top plan view illustrating a first mesh structure of an antenna insertion type electrode structure according to an exemplary embodiment. Figure 4 is a partially enlarged top plan view illustrating a second mesh structure of an antenna insertion type electrode structure according to an exemplary embodiment.

[0074] For ease of description, Figure 3 and Figure 4 A first mesh structure and a second mesh structure from an integrated hybrid mesh structure are shown, respectively. Figure 5 is a partially enlarged top plan view illustrating a hybrid mesh structure of first and second mesh structures of an antenna insertion type electrode structure according to an exemplary embodiment.

[0075] Reference Figure 3 The first mesh structure 50 may include first electrode lines 52 and second electrode lines 54 that intersect each other. The first electrode lines 52 may extend in a first direction, and the second electrode lines 54 may extend in a second direction.

[0076] The first direction may be parallel to the top surface of the substrate layer 100 and may be tilted at a predetermined angle relative to the column direction. The second direction may be parallel to the top surface of the substrate layer 100 and may be tilted at a predetermined angle relative to the row direction.

[0077] As described above, the first electrode lines 52 and the second electrode lines 54 may cross each other so that the first mesh structure 50 may have a structure in which the first unit cells 56 are assembled. The first unit cells 56 may have a rhombus or diamond shape.

[0078] As reference Figure 1 As described above, the first sensing electrodes 110 and the second sensing electrodes 130 may form a mesh structure along a predetermined sensing electrode region allocated to the first mesh structure 50. Figure 3 As shown by the middle dashed diamond, the first sensing electrode region 112 and the second sensing electrode region 132 may be allocated to the first mesh structure 50 .

[0079] like Figure 1 As shown, the first sensing electrode 110 and the second sensing electrode 130 may have polygonal shapes such as rhombus or diamond. Therefore, the first sensing electrode region 112 and the second sensing electrode region 132 may also have substantially the same shape as the first sensing electrode 110 and the second sensing electrode 130.

[0080] For example, the first sensing electrode region 112 and the second sensing electrode region 132 may be provided so that the first sensing electrode 110 and the second sensing electrode 130 may each include a predetermined number of first unit cells 56 .

[0081] Reference Figure 4 The second mesh structure 60 may include a third electrode line 62 and a fourth electrode line 64 that cross each other. The third electrode line 62 may extend in the third direction. The fourth electrode line 64 may extend in the fourth direction.

[0082] The third direction may be parallel to the top surface of the substrate layer 100 and may be tilted at a predetermined angle relative to the column direction. The fourth direction may be parallel to the top surface of the substrate layer 100 and may be tilted at a predetermined angle relative to the row direction.

[0083] In some embodiments, the third direction may be different from the first direction. The fourth direction may be different from the second direction. Therefore, the third electrode lines 62 and the fourth electrode lines 64 included in the second mesh structure 60 may extend in a direction different from the first electrode lines 52 and the second electrode lines 54.

[0084] The third electrode lines 62 and the fourth electrode lines 64 may intersect each other so that the second mesh structure 60 may have a structure in which the second unit cells 66 may be assembled. The second unit cells 66 may have a polygonal shape such as a rhombus or a diamond.

[0085] Reference Figure 1 The radiation pattern 160 can be formed by etching the mesh structure along the radiation pattern area assigned to the second mesh structure 60. Figure 4 As shown by the middle dashed diamond, the radiation pattern area 161 may be allocated to the second mesh structure 60 .

[0086] In an exemplary embodiment, the second mesh structure 60 may be formed by extending an electrode line from each side of the radiation pattern 160. Therefore, the third electrode line 62 and the fourth electrode line 64 may be an extension line from each side of the radiation pattern 160.

[0087] In addition, some of the second unit cells 66 included in the second mesh structure 60 may substantially form a boundary of the radiation pattern 160 .

[0088] Reference Figure 5 , the mesh structure 70 may have a Figure 3 and Figure 4 The first and second mesh structures 50 and 60 may be mixed or blended into one conductive layer. Thus, the mesh structure 70 may have a structure in which the first to fourth electrode lines 52, 54, 62, and 64 cross each other.

[0089] For example, after forming the mesh structure 70, the mesh structure 70 can be formed by Figure 4 The radiation pattern region 161 shown is formed by etching the mesh structure 70 to form the radiation pattern 160 .

[0090] As reference Figure 4As described above, the boundary of the radiation pattern 160 may be substantially defined by one second unit cell 66 included in the second mesh structure 60. Therefore, the boundary of the radiation pattern 160 may have a substantially seamless continuous linear shape without a sharp portion or protrusion generated when, for example, the electrode line portion between the vertices of the unit cell is cut.

[0091] Therefore, radiation directivity and radiation reliability achieved by the radiation pattern 160 may be improved, and a reduction in radiation efficiency due to the tip portion or the protrusion may be prevented.

[0092] You can follow the reference Figure 3 The mesh structure 70 is etched using the sensing electrode regions 112 and 132 so that portions of the mesh structure 70 corresponding to the radiation pattern 160 may not be etched or cut to form the sensing electrodes 110 and 130 .

[0093] Although not in Figure 3 and Figure 5 , but for ease of description, the portion of the mesh structure 70 corresponding to the transmission line 162 may be patterned to connect to the radiation pattern 160 while etching the radiation pattern region 161. In addition, the portion of the mesh structure 70 corresponding to the connection portion 115 may be patterned together to connect to the first sensing electrode 110.

[0094] As described above, according to exemplary embodiments, the sensing electrodes 110 and 130 and the radiation pattern 160 can be formed by etching one mesh structure 70. Therefore, a thin electrode structure in which touch sensing and antenna radiation can be implemented together can be manufactured without requiring an additional process or an additional layer for inserting the antenna pattern 170.

[0095] In addition, the mesh structure 70 may have a mixed structure of the first mesh structure 50 and the second mesh structure 60, so that randomness can be increased. Therefore, the regular overlap with the pixel structure of the display panel to which the antenna-inserted electrode structure is applied can be reduced, thereby reducing or avoiding the moire fringe phenomenon.

[0096] Figure 6 1 is a schematic top plan view showing an electrode arrangement in an antenna insertion type electrode structure according to an exemplary embodiment. Figure 6 Illustration of the sensing electrodes 110 and 130 or the first mesh structure is omitted.

[0097] Reference Figure 6 As described above, the substrate layer 100 may include the touch sensing region TR and the touch sensing antenna region TAR. The touch sensing antenna region TAR may be allocated around the touch sensing region TR.

[0098] For example, Figure 6 As shown in the dotted rectangle in FIG, the touch sensing antenna area TAR may be allocated to at least one of the two lateral areas, the upper area, and the lower area of the substrate layer 100 in a plan view.

[0099] In some embodiments, the lower region and one lateral region of the substrate layer 100 can be allocated as a touch sensing antenna region TAR, so that the antenna pattern 170 can be inserted. For example, the first radiation pattern 160a can be included in the lower region, and the second radiation pattern 160b can be included in one lateral region. The first radiation pattern 160a and the second radiation pattern 160b can have different sizes.

[0100] The third and fourth electrode lines 62 and 64 may extend from the boundary of the first radiation pattern 160a to define a second mesh structure. The fifth and sixth electrode lines 82 and 84 may extend from the boundary of the second radiation pattern 160b to define a third mesh structure.

[0101] Therefore, the mesh structure for forming the sensing electrodes 110 and 130 and the radiation patterns 160 a and 160 b may have a hybrid structure of the first to third mesh structures.

[0102] As described above, by adding a mesh structure, radiation patterns of different sizes can be inserted. Therefore, an antenna insertion electrode structure capable of performing radiation at multiple resonant frequencies can be realized.

[0103] Figure 7 is a schematic top plan view showing an image display device according to an exemplary embodiment. For example, Figure 7 An external shape of a window including an image display device is shown.

[0104] Reference Figure 7 The image display device 200 may include a display area 210 and a peripheral area 220. For example, the peripheral area 220 may be provided at two lateral portions and / or two end portions of the display area 210. The peripheral area 220 may correspond to, for example, a light shielding portion or a frame portion of the image display device.

[0105] The antenna insertion electrode structure may be provided on the display region 210 and the peripheral region 220 of the image display device 200 , and the first sensing electrode 110 and the second sensing electrode 130 of the touch sensing region TR may be arranged in the display region 210 .

[0106] The touch sensing antenna area TAR may be located on the display area 210 and the peripheral area 220. For example, the radiation pattern 160 of the antenna pattern 170 and the sensing electrodes 110 and 130 around the radiation pattern 160 may also be at least partially arranged in the display area 210. As described above, the use of a mesh structure may prevent the radiation pattern 160 and the sensing electrodes 110 and 130 from being visually recognized by the user.

[0107] Furthermore, the hybrid mesh structure as described above may be utilized, so that the visibility of the radiation pattern 160 may be further reduced, and the moire phenomenon of the pixel structure of the display panel may be effectively suppressed.

[0108] It can be set in the peripheral area 220 Figure 1 Signal pads 165 of antenna pattern 170 are shown. A touch sensor driver IC chip and an antenna driver IC chip may be disposed in peripheral region 220 to be electrically connected to sensing electrodes 110 and 130 and signal pads 165 of antenna pattern 170, respectively.
