Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority from Korean Patent Application No. 10-2020-0018271 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 user commands by selecting instructions 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 mentioned above, when a touch sensor and antenna are incorporated into a single image display device, a design structure is required to fit multiple electrodes into a limited space. For example, if the touch sensing electrode 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 electrode overlaps with the pixel structure of the image display device, the image quality of the image display device may be degraded due to an optical phenomenon such as a moiré 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

[0033] 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.

[0034] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, those skilled in the art will appreciate that these embodiments described with reference to the accompanying drawings are provided for further understanding of the spirit of the present invention and are not intended to limit the subject matter disclosed in the detailed description and the appended claims.

[0035] In the drawings, two directions parallel to the top surface of the substrate layer 100 and perpendicular to each other are referred to as a first direction and a second direction. For example, the first direction may correspond to the length direction of the antenna-inserted electrode structure or the image display device. The second direction may correspond to the width direction of the antenna-inserted electrode structure or the image display device.

[0036] 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'.

[0037] exist Figure 1 and Figure 2 In order to facilitate the description of the arrangement of the electrodes in the antenna insertion type electrode structure, each electrode is represented as a solid pattern. However, as will be referred to later Figure 3 As described, each electrode may have a mesh structure.

[0038] Reference Figure 1 and Figure 2 The antenna insertion type electrode structure may include a substrate layer 100 and sensing electrodes 110 and 130 and an antenna pattern 150 disposed on the substrate layer 100 .

[0039] The substrate layer 100 or the antenna-interposed electrode structure may include a touch sensing region TR and a touch antenna region TAR.

[0040] 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.

[0041] The touch antenna region TAR may include an antenna pattern 150 for implementing high-frequency or ultra-high-frequency communications (e.g., 3G, 4G, 5G, or higher). In an exemplary embodiment, some of the sensing electrodes 110 and 130 of the touch sensor may be distributed in the touch antenna region TAR along with the antenna pattern 150.

[0042] like Figure 1 As shown, the touch antenna region TAR may be allocated to an end portion or a side portion of the substrate layer 100 adjacent to the touch region TR.

[0043] The first sensing electrode 110 and the second sensing electrode 130 may be disposed on the touch sensing region TR and the touch 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.

[0044] The substrate layer 100 may include a supporting layer or a thin film substrate for forming the sensing electrodes 110 and 130 and the antenna pattern 150. For example, the substrate layer 100 may include a thin 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 polymer (COP), polyethylene terephthalate (PET), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyallyl compound, polyimide (PI), cellulose acetate propionate (CAP), polyethersulfone (PES), triacetyl cellulose (TAC), polycarbonate (PC), cycloolefin copolymer (COC), polymethyl methacrylate (PMMA), etc. Examples of inorganic insulating materials may include silicon oxide, silicon nitride, silicon oxynitride, and metal oxides.

[0045] In some embodiments, a layer or thin 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.

[0046] The substrate layer 100 may serve as a dielectric layer of the antenna pattern 150. 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.

[0047] The first sensing electrodes 110 may be arranged along a first direction. The first sensing electrodes 110 adjacent to each other in the first 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 so as 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 (e.g., a mesh structure) through the same patterning process and may be located at the same layer or at the same level.

[0048] Therefore, a first sensing electrode column extending in the first direction may be defined, and a plurality of first sensing electrode columns may be provided along the second direction.

[0049] The second sensing electrodes 130 may be arranged along the second direction. The second sensing electrodes 130 may each have an independent island pattern shape, and the second sensing electrodes 130 adjacent to each other in the second direction may be electrically connected to each other via the bridge electrode 135.

[0050] Therefore, a second sensing electrode row extending in the second direction may be defined, and a plurality of second sensing electrode rows may be provided along the first direction.

[0051] Figure 1 An example is shown in which the second sensing electrode row includes the bridging electrode 135 and the first sensing electrode column includes the connecting portion. However, the first sensing electrode column may be defined by the bridging electrode, and the second sensing electrode row may be defined by the connecting portion.

[0052] The sensing electrodes 110, 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 copper (Cu) or a copper alloy (e.g., copper-calcium (CuCa)). These may be used alone or in combination.

[0053] The sensing electrodes 110 , 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.

[0054] In some embodiments, the sensing electrodes 110, 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, 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. In this case, the metal layer can improve flexibility and reduce resistance, thereby increasing signal transmission speed. The transparent conductive oxide layer can also improve corrosion resistance and transparency.

[0055] like Figure 2 As shown, an insulating layer 140 may be formed on the substrate layer 100 to at least partially cover the sensing electrodes 110 and 130 and the connection portion 115. A bridge electrode 135 may be provided on the insulating layer 140 to electrically connect adjacent second sensing electrodes 130 to each other through, for example, contact holes 145 formed in the insulating layer 140.

[0056] A passivation layer 170 for protecting the touch sensor may be formed on the insulating layer 140 and the bridge electrode 135 .

[0057] The insulating layer 140 and the passivation layer 170 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.

[0058] In some embodiments, the sensing electrodes 110, 130 and the bridging electrode 135 can be configured as a bottom bridging structure. In this case, the bridging electrode 135 can be disposed below the sensing electrodes 110 and 130. For example, the bridging electrode 135 can include a low-resistance metal and can be disposed away from a visible surface (e.g., the top surface of the passivation layer 170), thereby reducing channel resistance and visual identification of the electrodes caused by light reflection.

[0059] The sensing electrodes 110 and 130 and the antenna pattern 150 may be disposed together on the touch antenna region TAR of the substrate layer 100. In an exemplary embodiment, the sensing electrodes 110 and 130 and the antenna pattern 150 may be located at the same layer or level.

[0060] Antenna pattern 150 may include a radiation pattern 152, a transmission line 155, and a signal pad 160. The boundary of radiation pattern 152 may have a polygonal shape, such as a rhombus or diamond shape. Transmission line 155 may extend from one end of radiation pattern 152. Signal pad 160 may be electrically connected to the end of transmission line 155. Antenna pattern 150 may include a conductive material substantially the same as or similar to sensing electrodes 110 and 130. For example, antenna pattern 150 may include the aforementioned metals, alloys, or transparent conductive oxides, and may have a multilayer structure of a metal layer and a transparent conductive oxide.

[0061] As referenced later Figure 3 As described, the radiation pattern 152 and the transmission line 155 may have a mesh structure including a plurality of electrode lines crossing each other therein. In one embodiment, the radiation pattern 152 and the transmission line 155 may be formed as a substantially single member including the mesh structure.

[0062] The signal pads 160 can be formed as a solid pattern including the above-mentioned metal or alloy to reduce feedback resistance. In one embodiment, a ground pad (not shown) can also be provided around each signal pad 160. The signal pads 160 can be electrically connected to the antenna driver IC chip via a conductive intermediate structure (e.g., a flexible printed circuit board (FPCB) and an anisotropic conductive film (ACF)).

[0063] like Figure 1 As shown, the radiation pattern 152 can have a rectangular shape, such as a diamond, and all diagonal lines of the radiation pattern 152 can be tilted relative to the first direction and the second direction. In some embodiments, the transmission line 155 can also be tilted relative to the first direction and the second direction. For example, the transmission line 155 and the diagonal lines of the radiation pattern 152 extending from the transmission line 155 can be tilted within a range of approximately 5° to 30° relative to the first direction.

[0064] The radiation pattern 152 may have a shape interposed between the sensing electrodes 110 and 130 in the touch antenna region TAR. Therefore, the sensing electrodes 110 and 130 adjacent to the radiation pattern 152 may have a shape partially cut off and removed from the shape of the sensing electrodes 110 and 130 in the touch antenna region TR by the radiation pattern 152.

[0065] As described above, the radiation pattern 152 of the antenna pattern 150 may be provided on the same plane or at the same level as the sensing electrodes 110 and 130 and may be interposed between the sensing electrodes 110 and 130. Thus, the antenna pattern 150 may be integrated with the touch sensor so that touch sensing and antenna radiation may be simultaneously implemented through one electrode layer.

[0066] Figure 3is a partially enlarged top plan view showing the configuration and arrangement of the antenna pattern and the sensing electrode in the antenna insertion type electrode structure according to an exemplary embodiment. For example, Figure 3 Shown Figure 1 1 and 2. The mesh structure included in the sensing electrodes 110, 130 and the antenna pattern 150 in the area marked by the dotted rectangle in FIG.

[0067] Reference Figure 3 , the mesh structure may include first and second electrode lines 50 and 60 intersecting each other. The mesh structure may include unit cells 70 defined by intersecting the first and second electrode lines 50 and 60 in a mesh or honeycomb shape.

[0068] In an exemplary embodiment, the unit cells 70 included in the mesh structure may have a polygonal shape such as a quadrangle, and a diagonal line 75 of the unit cell 70 may be inclined with respect to the first direction and the second direction.

[0069] As described above, the first direction may correspond to the length direction of the antenna-interposed electrode structure or the image display device, and the second direction may correspond to the width direction of the antenna-interposed electrode structure or the image display device.

[0070] The orientation of the unit cell 70 may be tilted relative to the length direction and the width direction, thereby suppressing or reducing the contact between the sensing electrodes 110 and 130 and the pixel 207 (see FIG. Figure 4 ) caused by the moiré phenomenon.

[0071] In an exemplary embodiment, the sensing electrodes 110 and 130 and the antenna pattern 150 may be formed by partially etching the mesh structure. For example, the boundaries of the sensing electrodes 110 and 130 and the boundary of the antenna pattern 150 may be defined and separated by the separation area 175 formed by etching the mesh structure.

[0072] As reference Figure 1 As described, the boundary of the radiation pattern 152 may have a substantially rectangular outline, such as a diamond shape. In an exemplary embodiment, each side of the radiation pattern 152 may be defined by a single first electrode line 50 or a single second electrode line 60 and may extend substantially continuously.

[0073] For example, the boundary of the radiation pattern 152 may not include a tip portion or a protrusion formed by the cut electrode lines 50 and 60 protruding outside the boundary, and the boundary of the radiation pattern 152 may have a substantially seamless straight line shape.

[0074] As described above, the boundary of the radiation pattern 152 may be a portion of the first and second electrode lines 50 and 60 that is inclined with respect to the first and second directions, thereby eliminating a tip portion or a protrusion.

[0075] Therefore, the radiation directivity and the radiation reliability achieved by the radiation pattern 152 can be enhanced, and a reduction in radiation efficiency caused by the tip portion or the protrusion can be prevented.

[0076] Sensing electrodes 110 and 130 may be defined around radiation pattern 152 by separation region 175. Boundaries of sensing electrodes 110 and 130 may include protrusions 90 formed by cutting electrode lines 50 and 60. Protrusions 90 may have, for example, a spike shape protruding from the boundaries of sensing electrodes 110 and 130.

[0077] The sensing electrodes 110 and 130 may include the protrusions 90, thereby increasing the area or volume of the conductor and reducing the channel resistance through the sensing electrodes 110 and 130. In addition, the protrusions 90 may provide a random characteristic to the arrangement of the sensing electrodes 110 and 130, thereby further reducing the moiré phenomenon.

[0078] The separation region 175 may further extend from the boundary of the radiation pattern 152 through a bent shape to define a transmission line 155 integrally connected to the radiation pattern 152 .

[0079] Figure 4 and Figure 5 is a schematic top plan view showing an image display device according to an exemplary embodiment. For example, Figure 4 The pixel structure of the display panel is schematically shown. Figure 5 The outer appearance of a window including an image display device is shown.

[0080] Reference Figure 4 , the display panel 205 may include a plurality of pixels 207 defined by the pixel defining layer 203 .

[0081] Each pixel electrode and an RGB organic light emitting layer or a liquid crystal layer formed on the pixel electrode may be provided in the pixel 207. The pixels 207 may be regularly arranged along the first direction and the second direction and may each have a rectangular grid shape.

[0082] According to the above exemplary embodiment, the unit cells 70 included in the mesh structure may be disposed to be inclined relative to each pixel 207 to prevent regular overlap between the sensing electrodes 110 and 130 and the pixels 207 and thereby prevent the moiré phenomenon.

[0083] The antenna-interposition type electrode structure according to the exemplary embodiment may be stacked on the display panel 205 to implement the image display device 200 to which a touch sensor and an antenna may be simultaneously applied.

[0084] Reference Figure 5 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 on two lateral portions and / or two end portions of the display area 210. The peripheral area 220 may correspond to a light shielding portion or a frame portion of the image display device, for example.

[0085] The antenna insertion electrode structure may be disposed 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 disposed in the display region 210 .

[0086] In addition, the touch antenna area TAR may be located on the display area 210 and the peripheral area 220. For example, the radiation pattern 152 of the antenna pattern 150 and the sensing electrodes 110 and 130 around the radiation pattern 152 may also be at least partially disposed in the display area 210. As described above, the use of a mesh structure may prevent the radiation pattern 152 and the sensing electrodes 110 and 130 from being visually recognized by the user.

[0087] It can be set in the peripheral area 220 Figure 1 The signal pad 160 of the antenna pattern 150 is shown. A touch sensor driver IC chip and an antenna driver IC chip may also be disposed in the peripheral area 220 so as to be electrically connected to the traces connected to the sensing electrodes 110 and 130 and the signal pad 160 of the antenna pattern 150, respectively.
