[0001] Cross-reference to related applications and priority claim

[0002] This application claims the benefit of Korean Patent Application No. 10-2019-0142233, filed on November 8, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present invention relates to an antenna module and a display device including the same. More particularly, the present invention relates to an antenna module including an antenna pattern and a touch sensor layer, and a display device including the same. Background Art

[0004] With the development of information technology, wireless communication technologies such as Wi-Fi, Bluetooth, etc. are combined with display devices in the form of, for example, smart phones. In this case, an antenna may be combined with the display device to provide a communication function.

[0005] With the rapid development of mobile communication technology, an antenna capable of high frequency or ultra-high frequency communication is required in a display device.

[0006] Furthermore, electronic devices capable of realizing image display and information input functions are being developed by combining a display device with a touch sensor or a touch panel, wherein a user's instructions can be input by selecting instructions displayed on the screen with a human hand or an object. For example, as disclosed in Korean Patent Application Publication No. 2014-0092366, touch screen panels have recently been developed in which a touch sensor is coupled to various image display devices.

[0007] When a touch sensor and antenna are included in a single display device, additional space is required to embed the antenna. Consequently, the construction of recent display devices with thin, compact designs may be limited. Furthermore, mutual signal interruption may occur between the antenna and the touch sensing electrodes, reducing operational reliability.

[0008] For example, Korean Patent Laid-Open Application No. 2003-0095557 discloses an antenna embedded in a mobile terminal, but does not consider compatibility with other electronic devices such as a touch sensor. Summary of the Invention

For example, the first electrode layer 110 and the second electrode layer 130 may have a three-layer structure of a transparent conductive oxide layer, a metal layer, and a transparent conductive oxide layer. In this case, the metal layer can improve flexibility and signal transmission speed, while the transparent conductive oxide layer can improve corrosion resistance and transparency.

[0053] Figures 2 to 4 is a schematic top plan view showing a stacked configuration of an antenna module according to an exemplary embodiment. Specifically, Figure 2 The electrode pattern structure of the first electrode layer 110 is shown. Figure 3 The electrode pattern structure of the second electrode layer 130 is shown. Figure 4 It's superimposed Figure 2 and Figure 3 Floor plan.

[0054] For ease of description, Figures 2 to 4 The substrate layer 100 and the insulating interlayer 120 are omitted in the figure. Figures 2 to 4 In the embodiment, two directions parallel to the top surface of the substrate layer 100 and crossing each other are defined as a first direction and a second direction. For example, the first direction and the second direction may be perpendicular to each other.

[0055] refer to Figure 2 , the first electrode layer 110 may include a plurality of first sensing electrode rows 110 a .

[0056] In an exemplary embodiment, the plurality of first sensing electrodes 112 may be arranged along the first direction. The first sensing electrodes 112 may be connected to each other by the first connection portion 111. For example, the first connection portion 111 may extend in the first direction and may be integrally connected to the plurality of first sensing electrodes 112.

[0057] Therefore, first sensing electrode rows 110a extending in the first direction may be defined.A plurality of first sensing electrode rows 110a may be disposed along the second direction.

[0058] In some embodiments, one first sensing electrode row 110 a may include two first connection portions 111 . For example, the upper portion and the lower portion of the first sensing electrode 112 may be connected to each other through the first connection portion 111 .

[0059] At least one first antenna space S1 may be formed in first sensing electrode row 110a. First antenna space S1 may be defined between adjacent first sensing electrodes 112 and first connection portions 111 facing each other. First antenna space S1 may be a vacant space formed by first sensing electrode row 110a.

[0060] In some embodiments, a plurality of first antenna spaces S1 may be repeatedly disposed in the first sensing electrode row 110a along the first direction. Figure 1 The insulating interlayer 120 shown in FIG. 1 may cover the first electrode layer 110 and fill the first antenna space S1 .

[0061] A portion of the first connection portion 111 that may cross the transmission line 145 of the antenna pattern as will be described later may be removed to form a first cutout region C1. For example, the first cutout region C1 may be formed in the first connection portion 111 formed at both ends of the first electrode layer 110.

[0062] refer to Figure 3 , the second electrode layer 130 may include a plurality of second sensing electrode columns 130 a .

[0063] In an exemplary embodiment, a plurality of second sensing electrodes 132 may be provided along the second direction. The second sensing electrodes 132 may be connected to each other by the second connection portion 131. For example, the second connection portion 131 may extend in the second direction and may be integrally connected to the plurality of second sensing electrodes 132.

[0064] Therefore, second sensing electrode columns 130a extending in the second direction may be defined.A plurality of second sensing electrode columns 130a may be arranged along the first direction.

[0065] In some embodiments, one second sensing electrode column 130 a may include two second connection portions 131 . For example, two transverse portions of a second sensing electrode 132 may be connected to each other through the second connection portion 131 .

[0066] At least one second antenna space S2 may be formed in second sensing electrode column 130a. Second antenna space S2 may be defined between second sensing electrode 132 and second connection portion 131 adjacent to and facing each other. Second antenna space S2 may be a vacant space formed by second sensing electrode column 130a.

[0067] In some embodiments, a plurality of second antenna spaces S2 may be repeatedly disposed in the second sensing electrode column 130 a along the second direction.

[0068] A portion of the second sensing electrode 132 crossing the transmission line 145 of the antenna pattern may be removed to form a second cutout region C2. For example, the second cutout region C2 may be formed at the second sensing electrode 132 disposed at one or both ends of the second sensing electrode column 130a.

[0069] The antenna pattern may include a radiation electrode 140 and a transmission line 145. In an exemplary embodiment, the antenna pattern may be arranged in the second antenna space S2.

[0070] In some embodiments, the radiation pattern 140 may be accommodated in the second antenna space S2. The transmission line 145 may be partially inserted into the second antenna space S2. In this case, the transmission line 145 may protrude from the second antenna space S2 to the outside of the second antenna space S2 through the second cutout area C2.

[0071] The radiation pattern 140 may have a shape of, for example, a polygonal plate, and the transmission line 145 may branch and extend from one side of the radiation pattern 140. The radiation pattern 140 and the transmission line 145 may be formed as a substantially integral and single member.

[0072] The signal pad 150 may be connected to one end of the transmission line 145 that may protrude through the second cutout region C2. For example, an antenna driving integrated circuit (IC) chip may be electrically connected to the signal pad 150 to perform feeding through the transmission line 145.

[0073] The signal pad 150 and the antenna driving IC chip may be electrically connected to each other through a circuit connection structure such as a flexible printed circuit board (FPCB) and / or an anisotropic conductive film (ACF).

[0074] The antenna pattern may be inserted into the second antenna space S2 formed at the end of the second sensing electrode column 130a. In one embodiment, the antenna patterns may each be inserted into the second antenna space S2 formed at both ends of the second sensing electrode column 130a.

[0075] In some embodiments, a dummy antenna pattern 147 may be inserted into a second antenna space S2 that does not accommodate an antenna pattern among the plurality of second antenna spaces S2. The antenna pattern and the dummy antenna pattern 147 may be electrically and physically separated from the second sensing electrode column 130a, and the dummy antenna pattern 147 may be configured as a floating electrode inserted into the second antenna space S2.

[0076] The dummy antenna patterns 147 may be distributed in the remaining second antenna spaces S2, thereby improving pattern uniformity on the front surface of the antenna module. Therefore, electrode visibility due to variations in electrode structure may be reduced or suppressed.

[0077] In some embodiments, the antenna pattern and the dummy antenna pattern 147 may have a mesh structure including the aforementioned metal, alloy, and / or transparent conductive oxide. Therefore, the transmittance of the antenna module may be improved, and electrode visibility may be more effectively prevented.

[0078] In one embodiment, the first sensing electrode rows 110 a and the second sensing electrode columns 130 a may also have a grid structure including the above-mentioned metal, alloy and / or transparent conductive oxide.

[0079] The signal pad 150 may be a solid pattern including the above metal or alloy to reduce the feed supply resistance and improve the signal transmission speed. In some embodiments, the ground pad 155 may be arranged around the signal pad 150 .

[0080] For example, a pair of ground pads 155 may be arranged to face each other while being spaced apart from the signal pad 150 and the transmission line 145 with the signal pad 150 interposed therebetween.

[0081] refer to Figure 4 The second electrode layer 130 may be stacked on the first electrode layer 110 so that the first antenna space S1 and the second antenna space S2 may be aligned to overlap each other. In a plan view, the antenna pattern may be provided to be arranged in the first antenna space S1 included in the first sensing electrode row 110a.

[0082] For example, the radiation pattern 140 may be commonly accommodated in the first antenna space S1 and the second antenna space S2. The transmission line 145 may commonly pass through the first cutout area C1 and the second cutout area C2.

[0083] Therefore, when projected or viewed in a plan view, the antenna pattern may not overlap with both first sensing electrode row 110a and second sensing electrode column 130a. Therefore, radiation through radiation pattern 140 and feeding through transmission line 145 can be performed without hindering the touch sensing operation of first sensing electrode row 110a and second sensing electrode column 130a.

[0084] Therefore, the desired directivity and gain characteristics of the antenna pattern can be achieved, thereby improving radiation reliability. In addition, the desired sensing sensitivity and sensing resolution can be achieved, while the generation of capacitance and channel current for touch sensing can be unimpeded by the antenna pattern.

[0085] Figure 5 and Figure 6 is a schematic top plan view illustrating a stacked configuration of antenna modules according to some exemplary embodiments.

[0086] refer to Figure 5 and Figure 6 , an antenna pattern including a radiation pattern 140 and a transmission line 145 may be included in the first electrode layer 110 .

[0087] In this case, the antenna pattern may be inserted into the first antenna space S1 formed in the first sensing electrode row 110a. The dummy antenna pattern 147 may be arranged in a first antenna space S1 in which no antenna pattern is inserted among the plurality of first antenna spaces S1.

[0088] when Figure 6 The second electrode layer 130 shown in FIG. Figure 5 When the first electrode layer 110 is shown, it has Figure 4 The antenna module having substantially the same structure is omitted.

[0089] In some embodiments, the first sensing electrode row 110a or the second sensing electrode column 110b, in which no antenna pattern is inserted, may extend into a substantially continuous solid sensing line shape without including the antenna spaces S1 and S2 therein.

[0092] For example, the second connection portions 131 included in the second sensing electrode column 130a may cross the first connection portions 111 included in the first sensing electrode row 110a. In this case, the first connection portions 111 may be cut or spaced apart with the second connection portions 131 interposed therebetween.

[0093] In an exemplary embodiment, the first connection portions 111 are spaced apart from the second connection portions 131 interposed therebetween, and the first connection portions 111 may be electrically connected to each other via the bridge electrode 160 .

[0094] For example, an insulating interlayer 120 covering the first sensing electrode rows 110a, the second sensing electrode columns 130a, and the antenna pattern may be formed, and a bridging electrode 160 may be formed on the insulating interlayer 120. The bridging electrode 160 may connect the separated first connection portions 111 to each other through contacts penetrating the insulating interlayer 120.

[0095] As described above, the antenna pattern may include a radiation pattern 140 and a transmission line 145. The antenna pattern may be located on the same plane as the first and second sensing electrode rows 110a and 130a and may be electrically and physically separated from the first and second sensing electrode columns 110a and 130a.

[0096] In an exemplary embodiment, an antenna space S may be formed as a blank space in the second sensing electrode column 130 a , and the radiation pattern 140 may be arranged in the antenna space S.

[0097] In some embodiments, a bridging electrode 160 may be formed on the top surface of the substrate layer 100, and an insulating interlayer 120 may be formed on the top surface of the substrate layer 100 to cover the bridging electrode 160. The first sensing electrode rows 110a, the second sensing electrode columns 130a, and the antenna pattern may be formed on the insulating interlayer 120. The first connection portions 111 included in the first sensing electrode rows 110a and separated from each other may be connected to each other via the bridging electrode 160 including contacts formed through the insulating interlayer 120.

[0099] refer to Figure 8 The display device 200 may include a display area 210 and a peripheral area 220. For example, the peripheral area 220 may be arranged at both ends and / or both side 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.

[0100] The antenna module described above can be arranged throughout the display area 210 and the peripheral area 220 of the display device 200. The radiation pattern 140 of the antenna pattern can also be provided in the display area 210. As described above, the radiation pattern 140 can be formed with a grid structure to prevent visual recognition by the user. Dummy antenna patterns 147 can be distributed throughout the display area 210.

[0101] The transmission line 145 may extend to the peripheral region 220 through the cutout regions C1 and C2 , and the signal pad 150 may be connected to the transmission line 145 in the peripheral region 220 .

[0102] The touch sensor driver IC chip and the antenna driver IC chip can be arranged together in the peripheral area 220. For example, a trace can extend from each of the first sensing electrode row and the second sensing electrode column to electrically connect to the touch sensor driver IC chip.
