しかし、アンテナをディスプレイやタッチパネルの上に配置した場合、ディスプレイやタッチパネルの抵抗が大きいと、電波を反射せずに吸収してしまい、アンテナの送受信において損失が大きくなってしまう。　 However, when the antenna is arranged on the display or the touch panel, if the resistance of the display or the touch panel is large, the radio waves are absorbed without being reflected, and the loss in transmitting and receiving the antenna becomes large. Twice
そこで、本発明は、上記事情に鑑み、５Ｇ帯で送受信可能なアンテナを含み、アンテナが使用する周波数での電磁波の損失を抑制することができるディスプレイモジュールの提供を目的とする。 Therefore, in view of the above circumstances, an object of the present invention is to provide a display module including an antenna capable of transmitting and receiving in the 5G band and capable of suppressing loss of electromagnetic waves at a frequency used by the antenna.

A display module comprising a panel has at least one good reflector between the transparent antenna and the display panel, or on the surface of the display panel, the good reflector between 2 GHz <f <50 GHz. At the frequency f in which the transparent antenna is used, the reflection amplitude of the electromagnetic wave> the transmission amplitude, and the reflection coefficient S11 is -1 dB or more.

The transparent antenna is changed to the configuration shown in FIG. 3, as shown by the dotted line arrow in FIG. , It may be provided between the touch panel 230 and the inner adhesive layer 281 or between the polarizing plate 282 and the outer adhesive layer 283. Twice
また、タッチパネル２３０は「オンセルタッチパネル用金属細線層」である。ここで「オンセル」とは、ディスプレイパネル２２０と独立した基板上に形成したタッチパネルを貼り付けるのではなく、ディスプレイパネル２２０の表面上に電極層を直接形成した構造を指す。あるいは、独立した基板上に形成したタッチパネル２３０を、ディスプレイパネル２２０に接着した、オンセルではないタッチパネル用金属細線（配線層）でもよい。　 Further, the touch panel 230 is a "metal thin wire layer for an on-cell touch panel". Here, "on-cell" refers to a structure in which an electrode layer is directly formed on the surface of the display panel 220, instead of attaching a touch panel formed on a substrate independent of the display panel 220. Alternatively, the touch panel 230 formed on an independent substrate may be bonded to the display panel 220, and may be a non-on-cell touch panel fine metal wire (wiring layer). Twice
ディスプレイパネル２２０は、例えば、液晶ディスプレイパネル、有機ＥＬ(Electro-luminescence)、又は、OLED（Organic　Light　Emitting　Diode）ディスプレイパネルであり、いずれの構成でも、ディスプレイモジュール１の最も下側に配置される。　 The display panel 220 is, for example, a liquid crystal display panel, an organic EL (Electro-luminescence), or an OLED (Organic Light Emitting Diode) display panel, and is arranged at the lowermost side of the display module 1 in any configuration. Twice
なお、ディスプレイモジュール１において、透明アンテナ１００は部分的に設けられるため、透明アンテナ１００が設けられる領域については、他の部分よりも、タッチパネル２３０、内側接着層２８１、偏光板２８２、又は/及び外側接着層２８３を薄くしたり、あるいは、内側接着層２８１、偏光板２８２、又は/及び外側接着層２８３を設けない構造にしたりしてもよい。これにより、ディスプレイモジュール１において、透明アンテナ１００の部分だけ盛り上がることを防止することができる。　 Since the transparent antenna 100 is partially provided in the display module 1, the area where the transparent antenna 100 is provided is the touch panel 230, the inner adhesive layer 281, the polarizing plate 282, and / and the outer side, as compared with the other parts. The adhesive layer 283 may be thinned, or the structure may be such that the inner adhesive layer 281, the polarizing plate 282, and / and the outer adhesive layer 283 are not provided. As a result, in the display module 1, it is possible to prevent only the portion of the transparent antenna 100 from rising. Twice
しかし、透明アンテナ１００が厚すぎると、透明アンテナのエッジ部が視認できたり、接着層２８１、２８３との境界に空気が混入しやすくなる、という課題が生じることが分かった。透明アンテナ１００の厚さは２００μｍ以下が好ましく、１５０μｍ以下がさらに好ましく、１００μｍ以下が特に好ましい。また、ハンドリングの容易性の観点から、透明アンテナ１００の厚さは１０μｍ以上が好ましく、５０μｍ以上がさらに好ましい。　 However, it has been found that if the transparent antenna 100 is too thick, the edge portion of the transparent antenna can be visually recognized, and air tends to be mixed in the boundary with the adhesive layers 281 and 283. The thickness of the transparent antenna 100 is preferably 200 μm or less, more preferably 150 μm or less, and particularly preferably 100 μm or less. Further, from the viewpoint of ease of handling, the thickness of the transparent antenna 100 is preferably 10 μm or more, more preferably 50 μm or more. Twice
また、図１、図２では、ディスプレイモジュール１は、＋－Y方向の両端部が、緩やかに曲面の形状である例を示したが、ディスプレイモジュールＤは、端部が曲がらない、平面形状であってもよい。その場合は、透明アンテナ１００も、平面形状であってもよい。なお、透明アンテナ１００が部分的に曲面になる場合は、後述する給電領域が曲面形状になる。　 Further, in FIGS. 1 and 2, the display module 1 shows an example in which both ends in the + -Y direction have a gently curved shape, but the display module D has a flat shape in which the ends do not bend. There may be. In that case, the transparent antenna 100 may also have a planar shape. When the transparent antenna 100 has a partially curved surface, the feeding region described later has a curved surface shape. Twice
ここで、透明アンテナ１００の下に設けられるタッチパネル２３０において、電磁波の吸収が大きい、即ち反射振幅が小さく、抵抗値が高いと、アンテナの損失性が高くなる。そこで、下記では、アンテナの損失を抑制できるタッチパネル２３０やディスプレイパネル２２０について説明する。なお、接着層２８１，２８３や、偏光板２８２は、電磁波が透過する層である。　 Here, in the touch panel 230 provided under the transparent antenna 100, if the absorption of electromagnetic waves is large, that is, the reflection amplitude is small and the resistance value is high, the loss property of the antenna is high. Therefore, the touch panel 230 and the display panel 220 that can suppress the loss of the antenna will be described below. The adhesive layers 281,283 and the polarizing plate 282 are layers through which electromagnetic waves are transmitted. Twice
（２－１．投影型静電容量方式のタッチパネルの一般的なセンサパターンと特性）　まず、投影型静電容量方式のタッチパネル（タッチセンサともいう）におけるセンサパターンの構成について図４～図７を用いて説明する。図４は、一般的な投影型静電容量方式のタッチパネル２３０のセンサパターンの模式図である。　 (2-1. General sensor patterns and characteristics of the projected capacitance type touch panel) First, FIGS. 4 to 7 show the configuration of the sensor pattern in the projected capacitive touch panel (also referred to as a touch sensor). It will be described using. FIG. 4 is a schematic diagram of a sensor pattern of a general projection type capacitance type touch panel 230. Twice
図４を参照して、タッチパネル２３０は、基板上に複数の第１電極３１、及び複数の第２電極３２が設けられ、複数の第１電極３１と接続する複数の第１配線３８、及び複数の第２電極３２と接続する複数の第２配線３９を備えている。　 With reference to FIG. 4, the touch panel 230 is provided with a plurality of first electrodes 31 and a plurality of second electrodes 32 on a substrate, and a plurality of first wirings 38 and a plurality of first electrodes 38 connected to the plurality of first electrodes 31. A plurality of second wirings 39 for connecting to the second electrode 32 of the above are provided. Twice
図４に示すように、投影型静電容量方式のタッチパネル２３０のセンサパターンでは、複数の電極３１，３２は、マトリクス状に配置されており、隣接する電極同士は容量結合している。指などの導電性物質が電極に近づくと、指と電極間との間に容量結合が発生し、電極間同士の容量結合値が、変化した部分を、接触位置として検出する。このような投影型静電容量方式では、タッチパネル２３０上の複数の位置を同時に検出できる。　 As shown in FIG. 4, in the sensor pattern of the projection type capacitance type touch panel 230, a plurality of electrodes 31 and 32 are arranged in a matrix, and adjacent electrodes are capacitively coupled to each other. When a conductive substance such as a finger approaches an electrode, a capacitive coupling occurs between the finger and the electrode, and a portion where the capacitive coupling value between the electrodes changes is detected as a contact position. In such a projection type capacitance method, a plurality of positions on the touch panel 230 can be detected at the same time. Twice
なお、タッチパネル２３０において、第１電極３１と第２電極３２は、異なる面又は異なる層に設けられている場合と同一面に設けられている場合がある。具体例を下記に示す。例えば、（１）１つのガラス基板に対して一方の面に第１電極３１、他方の面に第２電極３２が設けられている。（２）ガラス（プリント基板）を２層に重ねた構造において上層のガラス基板に第１電極３１、下層のガラス基板に第２電極３２が設けられている。（３）１つのフィルムに対して一方の面に第１電極３１、他方の面に第２電極３２が設けられている。（４）フィルムを２層に重ねた構造において上層のフィルムに第１電極３１、下層のフィルムに第２電極３２が設けられている。（５）第２電極３２と同一面内に第１電極３１の菱形電極部が設けられ、菱形電極間が異なる層に設けられたブリッジ電極によって接続されている。（１）～（４）は異なる面又は異なる層に設けられている場合であり、（５）は同一層に設けられている場合である。　 In the touch panel 230, the first electrode 31 and the second electrode 32 may be provided on different surfaces or on the same surface as when they are provided on different layers. Specific examples are shown below. For example, (1) a first electrode 31 is provided on one surface and a second electrode 32 is provided on the other surface with respect to one glass substrate. (2) In a structure in which glass (printed circuit board) is stacked in two layers, a first electrode 31 is provided on the upper glass substrate and a second electrode 32 is provided on the lower glass substrate. (3) A first electrode 31 is provided on one surface and a second electrode 32 is provided on the other surface of one film. (4) In a structure in which films are stacked in two layers, a first electrode 31 is provided on the upper film and a second electrode 32 is provided on the lower film. (5) The rhombic electrode portion of the first electrode 31 is provided in the same plane as the second electrode 32, and the rhombic electrodes are connected by bridge electrodes provided in different layers. (1) to (4) are cases where they are provided on different surfaces or different layers, and (5) are cases where they are provided on the same layer. Twice
図４に示すように、第１電極３１は、横方向（Ｘ方向）に串状につながっており、第２電極３２は、縦方向（Ｙ方向）に串状につながっている。そして、第１電極３１及び第２電極３２の輪郭は、共通の第１の直線L１と、第１の直線と直交する第２の直線によって形成されたひし形、又は正方形形状である。　 As shown in FIG. 4, the first electrode 31 is connected in a skewer shape in the horizontal direction (X direction), and the second electrode 32 is connected in a skewer shape in the vertical direction (Y direction). The contours of the first electrode 31 and the second electrode 32 are a rhombus or a square shape formed by a common first straight line L1 and a second straight line orthogonal to the first straight line. Twice
そして、複数の平行な直線L１と、複数の平行な直線L２を使用して四辺が構成された第１電極３１と第２電極３２において、隣接する辺は、距離ｄ離れている。　 Then, in the first electrode 31 and the second electrode 32 whose four sides are formed by using the plurality of parallel straight lines L1 and the plurality of parallel straight lines L2, the adjacent sides are separated by a distance d. Twice
距離ｄは、小さいほど電極間の隙間が視認できなくなる点では好ましいが、距離ｄの部分が広すぎると、電極３１や電極３２が存在しない領域が視認されてしまうこともありうる。しかし、距離ｄを小さくするほど、異なる層間での位置調整が難しく、製造工程が複雑になる。間隔ｄの大きさとしては、例えば０より大きく１０ｍｍ以下、好ましくは１μｍ以上５ｍｍ以下、より好ましくは３μｍ以上１ｍｍ以下、より好ましくは５μｍ以上５００μｍ以下などとすればよい。　 The smaller the distance d, the less visible the gap between the electrodes is. However, if the distance d is too wide, the region where the electrodes 31 and 32 do not exist may be visible. However, the smaller the distance d, the more difficult it is to adjust the position between different layers, and the more complicated the manufacturing process becomes. The size of the interval d may be, for example, larger than 0 and 10 mm or less, preferably 1 μm or more and 5 mm or less, more preferably 3 μm or more and 1 mm or less, and more preferably 5 μm or more and 500 μm or less. Twice
図５は、一般的なタッチパネル２３０Ｘのセンサパターンの詳細構成を示す図である。図５では、２種類の電極３１，３２が周期的に配置されており、図５は、複数の周期構造が並んだ図である。　 FIG. 5 is a diagram showing a detailed configuration of a sensor pattern of a general touch panel 230X. In FIG. 5, two types of electrodes 31 and 32 are periodically arranged, and FIG. 5 is a diagram in which a plurality of periodic structures are arranged side by side. Twice
図６は、電極を構成する金属細線の格子の拡大図である。図７は、図５のタッチパネル２３０Ｘのセンサパターンの電極の角部、延伸部及びジャンパーの部分拡大図である。図７は図５の実線αで囲まれた部分の拡大図であって、周期構造の、交差部分を拡大したものである。　 FIG. 6 is an enlarged view of a grid of thin metal wires constituting the electrodes. FIG. 7 is a partially enlarged view of a corner portion, an extension portion, and a jumper of the electrode of the sensor pattern of the touch panel 230X of FIG. FIG. 7 is an enlarged view of the portion surrounded by the solid line α in FIG. 5, which is an enlarged view of the intersecting portion of the periodic structure. Twice
図５～図７で示すように、電極３１及び電極３２は、格子状（メッシュ状）の金属ワイヤーで形成されている。詳しくは、電極３１は、直線Ｌ１と平行な輪郭辺３１１と、直線Ｌ２と平行な輪郭辺３１２を有し、直線Ｌ１方向と平行な複数の区切り線３１３、直線Ｌ２方向と平行な複数の区切り線３１４を有する。電極３２は、直線Ｌ１と平行な輪郭辺３２１と、直線Ｌ２と平行な輪郭辺３２２を有し、直線Ｌ１方向と平行な複数の区切り線３２３、直線Ｌ２方向と平行な複数の区切り線３２４を有する。　 As shown in FIGS. 5 to 7, the electrode 31 and the electrode 32 are formed of a lattice-shaped (mesh-shaped) metal wire. Specifically, the electrode 31 has a contour side 311 parallel to the straight line L1 and a contour side 312 parallel to the straight line L2, a plurality of dividing lines 313 parallel to the straight line L1 direction, and a plurality of dividing lines parallel to the straight line L2 direction. It has line 314. The electrode 32 has a contour side 321 parallel to the straight line L1 and a contour side 322 parallel to the straight line L2, and has a plurality of dividing lines 323 parallel to the straight line L1 direction and a plurality of dividing lines 324 parallel to the straight line L2 direction. Have. Twice
図６は、図５の四角γで囲まれた部分の拡大図であって、電極を構成する金属細線の格子の拡大図である。図６に示すように、電極のメッシュを構成する金属ワイヤー線（格子を構成する線）である区切り線３１３，３１４は、さらに細い複数の金属細線Ｗによって構成されている。ここで例えば金属細線Ｗ間のピッチは大凡３４μｍ、金属細線の厚みは大凡３００ｎｍ、金属細線の幅は大凡３μｍである。これらの金属細線は、使用者から視認されない程度に細く加工されることで、格子状に加工しても、タッチパネル２３０Ｘにおける高い導電性を得ることができる。　 FIG. 6 is an enlarged view of the portion surrounded by the square γ of FIG. 5, and is an enlarged view of a grid of thin metal wires constituting the electrodes. As shown in FIG. 6, the dividing lines 313 and 314, which are the metal wire wires (lines forming the lattice) constituting the mesh of the electrodes, are composed of a plurality of finer metal wire Ws. Here, for example, the pitch between the thin metal wires W is about 34 μm, the thickness of the thin metal wires is about 300 nm, and the width of the thin metal wires is about 3 μm. By processing these thin metal wires so that they are not visible to the user, high conductivity in the touch panel 230X can be obtained even if they are processed in a grid pattern. Twice
図６の太線で示す、斜線で示す区切り線３１３，３１４の内部は、梯子状の金属細線Ｗでつながっているが、区切り線３１３，３１４の領域から飛び出ている金属細線は途中で途切れている。区切り線３１３，３１４によって区画された空間（Ｆで示す濃い部分）内にある金属細線は、区切り線３１３，３１４とは、導通していない。内側に囲まれた略正方形の部分は周囲と導通しておらず、いわゆる浮遊導体（フロート）Ｆを構成している。この構成では、金属細線Ｗが途切れた、区切り線３１３、３１４側の金属細線の端部と、浮遊導体Ｆ側の金属細線の端部との間には、略一律の間隔Ｇが空いている。　 The insides of the dividing lines 313 and 314 indicated by the thick lines in FIG. 6 are connected by a ladder-shaped thin metal line W, but the thin metal lines protruding from the region of the dividing lines 313 and 314 are interrupted in the middle. .. The thin metal wire in the space (dark portion indicated by F) partitioned by the dividing lines 313 and 314 is not conductive with the dividing lines 313 and 314. The substantially square portion surrounded by the inside does not conduct with the surroundings and constitutes a so-called floating conductor (float) F. In this configuration, there is a substantially uniform gap G between the end of the metal thin wire on the dividing line 313 and 314 side and the end of the metal thin wire on the floating conductor F side where the metal thin wire W is interrupted. .. Twice
そして、浮遊導体Ｆ内の格子状の金属細線で区画される空間、及び区切り線３１３、３１４の梯子状の線間の空間において、下層のディスプレイパネル２２０の発光層（発光素子）２５Ｒ，２５Ｇ，２５Ｂ（図２８参照）が露出することで、発光を妨害しないように設けられる。これにより、タッチパネル２３０がオンセルで設けられても、ディスプレイパネル２２０の高い視認性を損なわないことができる。　 Then, in the space partitioned by the grid-like thin metal wires in the floating conductor F and the space between the ladder-shaped lines of the dividing lines 313 and 314, the light emitting layers (light emitting elements) 25R and 25G of the lower display panel 220 are used. By exposing 25B (see FIG. 28), it is provided so as not to interfere with light emission. As a result, even if the touch panel 230 is provided on-cell, the high visibility of the display panel 220 can be maintained. Twice
なお、図６では、電極３１の区切り線３１３と、３１４の拡大図を示しているが、電極３２の区切り線３２３と３２４でも同様の構成を有している。また、電極３１の角部である、輪郭辺３１１と、輪郭辺３１２を含んで、区切り線３１３，３１４に囲まれる空間においても、同様に、区画された空間の内部は浮遊導体Ｆとなっている。電極３２でも同様である。　 Although FIG. 6 shows an enlarged view of the dividing lines 313 and 314 of the electrode 31, the dividing lines 323 and 324 of the electrode 32 have the same configuration. Further, also in the space including the contour side 311 and the contour side 312, which are the corners of the electrode 31, and surrounded by the dividing lines 313 and 314, the inside of the partitioned space also becomes a floating conductor F. There is. The same applies to the electrode 32. Twice
このように、金属細線の一部を切断、あるいはブリッジさせることにより、任意のパターン形状を作成することが可能であり、この細線の接続、切断を、位置検出に適した配線にすることで、金属細線層をタッチパネルとして動作させることが可能であ
る。　 In this way, it is possible to create an arbitrary pattern shape by cutting or bridging a part of the thin metal wire, and by connecting and cutting the thin metal wire, the wiring is suitable for position detection. It is possible to operate the thin metal wire layer as a touch panel.
電極３１及び電極３２の金属細線Ｗの最も細い部分の幅を、３０ｎｍ以上１００μｍ以下、好ましくは５０ｎｍ以上５０μｍ以下、より好ましくは５０ｎｍ以上２０μｍ以下とすることが好ましい。特に、１０μｍ以下のパターン幅を有する導電膜は、使用者が視認することが極めて困難となるため好ましい。また電極３１及び電極３２に、導電性のナノワイヤを用いてもよい。隣接するナノワイヤ同士が接触するように、適当な密度で分散することにより、２次元的なネットワークが形成され、極めて透光性の高い導電膜として機能させることができる。例えば直径の平均値が１ｎｍ以上１００ｎｍ以下、好ましくは５ｎｍ以上５０ｎｍ以下、より好ましくは５ｎｍ以上２５ｎｍ以下のナノワイヤを用いることができる。ナノワイヤとしては、Ａｇナノワイヤや、Ｃｕナノワイヤ、Ａｌナノワイヤ等の金属ナノワイヤ、または、カーボンナノチューブなどを用いることができる。　 The width of the narrowest portion of the thin metal wire W of the electrode 31 and the electrode 32 is preferably 30 nm or more and 100 μm or less, preferably 50 nm or more and 50 μm or less, and more preferably 50 nm or more and 20 μm or less. In particular, a conductive film having a pattern width of 10 μm or less is preferable because it is extremely difficult for the user to visually recognize it. Further, conductive nanowires may be used for the electrode 31 and the electrode 32. By dispersing the adjacent nanowires at an appropriate density so that they come into contact with each other, a two-dimensional network is formed, and the film can function as a conductive film having extremely high translucency. For example, nanowires having an average diameter of 1 nm or more and 100 nm or less, preferably 5 nm or more and 50 nm or less, and more preferably 5 nm or more and 25 nm or less can be used. As the nanowires, Ag nanowires, metal nanowires such as Cu nanowires and Al nanowires, carbon nanotubes, and the like can be used. Twice
また、図７は、注目する周波数帯の電磁波として妥当な範囲で簡略化した模擬図である。電極３１，３２を構成するひし形の一辺は４ｍｍ程度である。図中、濃い色の部分と、薄い色の部分とは、導通しておらず、濃い色（３２）同士、薄い色（３１）同士は導通するように、ブリッジ電極等で短絡させている。即ち、図５、図７に示す、電極３１を構成する線３１１、３１２、３１３、３１４と延伸部３３１、３３２、３３３、３３４は、導通している。電極３２を構成する線３２１、３２２、３２３、３２４と延伸部３４１、３４２、３４３、３４４は導通している。　 Further, FIG. 7 is a simulated diagram simplified within a reasonable range as an electromagnetic wave in the frequency band of interest. One side of the rhombus constituting the electrodes 31 and 32 is about 4 mm. In the figure, the dark-colored portion and the light-colored portion are not electrically connected, and the dark-colored portions (32) and the light-colored portions (31) are short-circuited by a bridge electrode or the like so as to be electrically connected to each other. That is, the lines 311, 312, 313, 314 and the extending portions 331, 332, 333, 334 which form the electrode 31 shown in FIGS. 5 and 7 are conducting with each other. The wires 321, 322, 323, 324 and the extending portions 341, 342, 343, and 344 that form the electrode 32 are conductive. Twice
そして、図７にて線状の空白で示す、電極３１と電極３２の境界の部分は、スリットＳ１、Ｓ２となっている。例えば、電極３１，３２の輪郭線間の距離ｄは30umである。なお、図７では、例えば電極３１，３２のひし形内では、図６の浮遊導体Ｆはないものとして置き換えている。このようにしても５Ｇの周波数帯であるGHｚ帯では、妥当であることを確認している。　 The boundary portion between the electrode 31 and the electrode 32, which is shown by a linear blank in FIG. 7, is slits S1 and S2. For example, the distance d between the contour lines of the electrodes 31 and 32 is 30 um. In FIG. 7, for example, in the diamonds of the electrodes 31 and 32, the floating conductor F in FIG. 6 is replaced as if it were not present. Even in this way, it has been confirmed that it is appropriate in the GHz band, which is the frequency band of 5G. Twice
また、図５、図７に示すように、電極３１、３２の間の間隔ｄにおいて対向する電極３１,３２の辺から延伸部（３３１、３３２、３３３、３３４）、（３４１、３４２、３４３、３４４）が伸び出している。　 Further, as shown in FIGS. 5 and 7, extending portions (331, 332, 333, 334), (341, 342, 343,) from the sides of the electrodes 31, 32 facing each other at the interval d between the electrodes 31 and 32. 344) is growing. Twice
この構成により、電極３１，３２のひし形の輪郭の位置を変えずに、電極３１，３２間の距離を近づけることができる。また、このような構成とすることで、電極３１や電極３２が存在しない距離ｄの領域が視認されてしまうことを抑制できる。　 With this configuration, the distance between the electrodes 31 and 32 can be shortened without changing the position of the diamond-shaped contours of the electrodes 31 and 32. Further, with such a configuration, it is possible to prevent the region of the distance d where the electrodes 31 and 32 do not exist from being visually recognized. Twice
ここで、直線Ｌ１と平行な辺３１１、３２１に対して直交して伸び出す第１電極３１の延伸部３３１と、第２電極３２の延伸部３４１との境界部分が、スリットＳ１となる。また、直線Ｌ２と平行な辺３１２、３２２に対して直交して伸び出す第１電極３１の延伸部３３２と、第２電極３２の延伸部３４２の境界部分が、スリットＳ２となる。　 Here, the boundary portion between the stretched portion 331 of the first electrode 31 extending perpendicular to the sides 311 and 321 parallel to the straight line L1 and the stretched portion 341 of the second electrode 32 becomes the slit S1. Further, the boundary portion between the stretched portion 332 of the first electrode 31 and the stretched portion 342 of the second electrode 32 extending orthogonally to the sides 312 and 322 parallel to the straight line L2 becomes the slit S2. Twice
図５、図７に示すように、交差部において、第１電極３１は、Ｘ方向で隣り合う導電延伸部である角部延伸部３３４同士が接触することで隣同士接触しているが、第２電極３２は、延伸部３４３同士は接触していない。そのため、第２電極３２の角部延伸部３４３をＹ方向で連結すべく、ジャンパー３５の配線が形成されている。なお、ジャンパー３５は、Ｙ軸とＸ軸の交点となる部分に設けられている。一方、軸同士の交点とならない延伸部３３３、３４４（図５参照）の交差部では、角部延伸部３３３が互いに接続することで第１電極３１がＸ軸方向に連続的に形成されているが、ジャンパーが設けられていないため電極３２はＹ軸方向には接続されていない。　 As shown in FIGS. 5 and 7, at the intersection, the first electrode 31 is in contact with each other due to the contact between the corner extension portions 334 which are the conductive stretched portions adjacent to each other in the X direction. The two electrodes 32 are not in contact with each other in the stretched portions 343. Therefore, the wiring of the jumper 35 is formed so as to connect the corner extension portion 343 of the second electrode 32 in the Y direction. The jumper 35 is provided at a portion serving as an intersection of the Y-axis and the X-axis. On the other hand, at the intersection of the extension portions 333 and 344 (see FIG. 5) which do not intersect the axes, the first electrode 31 is continuously formed in the X-axis direction by connecting the corner extension portions 333 to each other. However, since the jumper is not provided, the electrode 32 is not connected in the Y-axis direction. Twice
図８は、タッチパネル２３０Ｘの断面図の一例である。図８では、上述の（５）第２電極３２と同一面内に第１電極３１の菱形電極部が設けられ、菱形電極間が異なる層に設けられたブリッジ電極によって接続されている場合の構成例を示している。　 FIG. 8 is an example of a cross-sectional view of the touch panel 230X. In FIG. 8, the rhombic electrode portion of the first electrode 31 is provided in the same plane as the above-mentioned (5) second electrode 32, and the rhombic electrodes are connected by bridge electrodes provided in different layers. An example is shown. Twice

透明アンテナ１００は、透明基材１０１を備え、透明基材１０１の上面上に、アンテナパターン１１０と、配線領域である面状給電部１２０が設けられている。本発明の透明アンテナ１００におけるアンテナパターンは、モノポールアンテナに限られず、アンテナパターンは、下面側にバックグラウンドを有さない種類のアンテナであるとアンテナ厚みを薄くすることができる点で、好適である。　 The transparent antenna 100 includes a transparent base material 101, and an antenna pattern 110 and a planar feeding portion 120 which is a wiring region are provided on the upper surface of the transparent base material 101.

FIG. 10 is a portion surrounded by the dotted line β in FIG. 5, and in the touch panel 230X in the pseudo display module SD, the partially cut out electrodes 31 and 32 are one by one (two divided into two). ) Included, centered around the corner with the jumper 35.

図１１は、図９の疑似ディスプレイモジュールＳＤについて、電磁波のシミュレーションにより得られた、水平偏波及び垂直偏波のＳ１１、Ｓ２１パラメータの周波数特性を示す図である。図１１において、横軸は周波数（GHz)、縦軸は、パラメータの値（dB）を示す。この値は、例えばフリースペース法などの公知の電磁波測定方法にて、実測できる量である。　 FIG. 11 is a diagram showing the frequency characteristics of the S11 and S21 parameters of horizontally polarized waves and vertically polarized waves obtained by simulating electromagnetic waves for the pseudo display module SD of FIG. In FIG. 11, the horizontal axis represents the frequency (GHz) and the vertical axis represents the parameter value (dB). This value is an amount that can be actually measured by a known electromagnetic wave measuring method such as the free space method. Twice
図１１に示すように、28GHzでは、反射増幅を示す反射係数Ｓ１１が、-3.45dBと低い。即ち、図９の疑似ディスプレイモジュールＳＤにおいて、28GHz帯では、アンテナからの電磁波の損失率が大きい。そのため、図８の構成のタッチパネル２３０Ｘを電子機器２００において、28GHz帯に使用すると、ディスプレイモジュール１における透明アンテナ１００の電波損失が大きくなってしまう。　 As shown in FIG. 11, at 28 GHz, the reflectance coefficient S11 indicating reflection amplification is as low as -3.45 dB. That is, in the pseudo display module SD of FIG. 9, the loss rate of electromagnetic waves from the antenna is large in the 28 GHz band. Therefore, when the touch panel 230X having the configuration shown in FIG. 8 is used in the 28 GHz band in the electronic device 200, the radio wave loss of the transparent antenna 100 in the display module 1 becomes large. Twice
反射係数Ｓ１１は、-1dB以上が好ましく、-0.8dB以上がより好ましく、-0.6dB以上がさらに好ましく、-0.4dB以上が特に好ましい。　 The reflectance coefficient S11 is preferably -1 dB or more, more preferably -0.8 dB or more, further preferably -0.6 dB or more, and particularly preferably -0.4 dB or more. Twice
また、一般的に、導体板の面抵抗［Ω/ｓｑ］と反射係数に対しては、いわゆるシェルクノフの式を用いたり、板厚内の干渉が無視できない場合は転送行列法を用いたりすることによって、相関があることを示すことができる。このように計算された、良反射板（本例ではタッチパネル２３０）の面抵抗[Ω/ｓｑ]は、５Ω/ｓｑ以下であることが好ましく、３Ω/ｓｑ以下であることがより好ましく、１Ω/ｓｑであることが特に好ましい。　 In general, for the surface resistance [Ω / sq] and reflectance coefficient of the conductor plate, the so-called Shelknov's equation should be used, or if the interference within the plate thickness cannot be ignored, the transfer matrix method should be used. Can be shown to be correlated. The surface resistance [Ω / sq] of the good reflector (touch panel 230 in this example) calculated in this way is preferably 5Ω / sq or less, more preferably 3Ω / sq or less, and 1Ω / sq or less. It is particularly preferable that it is sq. Twice
また、図１１に示すように、Ｓ１１とＳ２１において、水平偏波と垂直偏波は、ほぼ同じ周波数特性であり、特性に差がない。　 Further, as shown in FIG. 11, in S11 and S21, the horizontally polarized waves and the vertically polarized waves have substantially the same frequency characteristics, and there is no difference in the characteristics. Twice
そこで、注目する周波数帯域で、Ｓ１１をあげるように調整する手法について、下記、説明する。　 Therefore, a method of adjusting so as to raise S11 in the frequency band of interest will be described below. Twice
＜５Ｇの周波数帯域と本発明の透明アンテナの動作帯域例＞　図１２は、各国の第５世代移動通信システム（５Ｇ）に割り当てられた周波数帯を示す図である。　 <Example of 5G frequency band and operating band of the transparent antenna of the present invention> FIG. 12 is a diagram showing a frequency band assigned to the 5th generation mobile communication system (5G) of each country. Twice
図１２に示すように、５G帯において、１つの周波数帯は、24.2～29.5GHzであり、２つ目の周波数帯は、37.3～40GHzであり、３つ目の周波数帯は、1.0～5.0GHzである。そのため、本発明の透明アンテナ１００は、５Ｇ帯において、上記の３つの周波数帯域のうちの１つで共振するように設定される。　 As shown in FIG. 12, in the 5G band, one frequency band is 24.2 to 29.5 GHz, the second frequency band is 37.3 to 40 GHz, and the third frequency band is 1.0 to 5.0 GHz. Is. Therefore, the transparent antenna 100 of the present invention is set to resonate in one of the above three frequency bands in the 5G band. Twice
また、図１２に示すように、特に、24.2～29.5GHz（例えば、中心周波数を28GHzとする）は、多くの国で使用される帯域であるため、この周波数帯で共振できると、より好適である。　 Further, as shown in FIG. 12, in particular, 24.2 to 29.5 GHz (for example, the center frequency is 28 GHz) is a band used in many countries, so it is more preferable to be able to resonate in this frequency band. be. Twice
例えば、図９の構成の疑似ディスプレイモジュールＳＤでは、図１１に示すように37.3～40GHz、及び1.0～5.0GHzでは、反射係数が-1dB以上であるため、使用に適するが、24.2～29.5GHzは、反射係数が、-3.45dBであるため、反射が少なく電磁波を吸収してしまうため、使用に適しないと考えられる。　 For example, in the pseudo display module SD having the configuration shown in FIG. 9, as shown in FIG. 11, the reflection coefficient is -1 dB or more at 37.3 to 40 GHz and 1.0 to 5.0 GHz, so that it is suitable for use, but 24.2 to 29.5 GHz is suitable. Since the reflection coefficient is -3.45 dB, there is little reflection and it absorbs electromagnetic waves, so it is considered unsuitable for use. Twice
（３－１．本発明の第１構成例に係るタッチパネルのセンサパターンと特性）　図１３は、本発明の第１構成例に係るタッチパネル２３０のセンサパターンの拡大図である。図１３に示す構成では、図６に示す構成と比較して、第１電極３１の辺３１１から伸び出す延伸部３３１，３３３と、第２電極３２の辺３２１から伸び出す延伸部３４１，３４３との境界部分であるスリットＳＡが、スリットＳ１よりも細い。同様に、第１電極３１の辺３１２から伸び出す延伸部３３２と、第２電極３２の辺３２２から伸び出す延伸部３４２との境界部分であるスリットＳＢが、スリットＳ２よりも細い。　 (3-1. Sensor pattern and characteristics of the touch panel according to the first configuration example of the present invention) FIG. 13 is an enlarged view of the sensor pattern of the touch panel 230 according to the first configuration example of the present invention. In the configuration shown in FIG. 13, as compared with the configuration shown in FIG. 6, the stretched portions 331 and 333 extending from the side 311 of the first electrode 31 and the stretched portions 341 and 343 extending from the side 321 of the second electrode 32 The slit SA, which is the boundary portion of the above, is thinner than the slit S1. Similarly, the slit SB, which is the boundary portion between the extending portion 332 extending from the side 312 of the first electrode 31 and the extending portion 342 extending from the side 322 of the second electrode 32, is thinner than the slit S2. Twice
このようにスリットＳＡ、ＳＢを細くすることで、横電極である第１電極３１と、縦電極である第２電極３２との、実質的な間隔が狭くなり、並列の容量性を上げることでピーク特性を変化させることが期待できる。　 By thinning the slits SA and SB in this way, the substantial distance between the first electrode 31 which is the horizontal electrode and the second electrode 32 which is the vertical electrode is narrowed, and the capacitance in parallel is increased. It can be expected to change the peak characteristics. Twice
図１４は、図１３のタッチパネル２３０の構成を最下層に含んだ、疑似ディスプレイモジュールにした際の、Ｓ１１、Ｓ２１パラメータの周波数特性を示す図である。本測定では、タッチパネル２３０のスリットＳＡ、ＳＢの太さは２μｍに設定し、他の寸法は、上述の疑似ディスプレイモジュールＳＤの寸法と同様である。　 FIG. 14 is a diagram showing the frequency characteristics of the S11 and S21 parameters when the pseudo display module includes the configuration of the touch panel 230 of FIG. 13 in the lowermost layer. In this measurement, the thicknesses of the slits SA and SB of the touch panel 230 are set to 2 μm, and the other dimensions are the same as the dimensions of the pseudo display module SD described above. Twice
図１４のグラフと、図１１のグラフとを比較するとピークの位置が低域側にシフトして、かつＳ１１のピーク値が大きくなっている。そのため、図１４のタッチパネル２３０の構成を有する疑似ディスプレイモジュールの特性において、24.2～29.5GHz、37.3～40GHz、1.0～5.0GHzのいずれの周波数に
おいても、反射係数Ｓ１１は-1dBであって、全ての帯域であって、反射係数Ｓ１１＞透過係数Ｓ２１の関係となっている。　 Comparing the graph of FIG. 14 with the graph of FIG. 11, the peak position is shifted to the low frequency side, and the peak value of S11 is large. Therefore, in the characteristics of the pseudo display module having the configuration of the touch panel 230 of FIG. 14, the reflectance coefficient S11 is -1 dB at any frequency of 24.2 to 29.5 GHz, 37.3 to 40 GHz, and 1.0 to 5.0 GHz, and all of them. It is a band, and the relationship is that the reflection coefficient S11> the transmission coefficient S21.
このため、疑似ディスプレイモジュールにおける、最下層の本構成のタッチパネル２３０は、電磁波の反射振幅＞透過振幅となり、透明アンテナ１００に対して良反射板となる。　 Therefore, the touch panel 230 having the present configuration on the lowermost layer in the pseudo display module has the reflection amplitude> the transmission amplitude of the electromagnetic wave, and is a good reflection plate with respect to the transparent antenna 100. Twice
このように、タッチパネルのセンサパターンにおけるスリットの太さを変更することで、ピークの位置をずらし、タッチパネルにおいて、使用するアンテナの周波数の電波を妨害しないように、最適化することができる。　 In this way, by changing the thickness of the slit in the sensor pattern of the touch panel, the position of the peak can be shifted and the touch panel can be optimized so as not to interfere with the radio wave of the frequency of the antenna to be used. Twice
なお、図１、図２に示したように、透明アンテナ１０は、ディスプレイモジュール１の一部に設けられている。そのため、タッチパネル２３０において、少なくともアンテナの下層に設けられる領域については、図１４に示すように、アンテナを使用する周波数において、「良反射板」となる構成であると好適である。　 As shown in FIGS. 1 and 2, the transparent antenna 10 is provided in a part of the display module 1. Therefore, in the touch panel 230, at least the region provided in the lower layer of the antenna is preferably configured to be a “good reflector” at the frequency at which the antenna is used, as shown in FIG.

Sensor pattern and characteristics of the touch panel according to the second configuration example of the present invention) FIG. 15 is an enlarged view of the sensor pattern of the touch panel 230A according to the second configuration example of the present invention. In the configuration shown in FIG. 15, as compared with the configuration shown in FIG. 6, the stretched portions 331 and 333 extending from the side 311 of the first electrode 31 and the stretched portions 341 and 343 extending from the side 321 of the second electrode 32 The slit SC, which is the boundary portion of the above, is thicker than the slit S1. Similarly, the slit SD, which is the boundary between the stretched portions 332 and 334 extending from the side 312 of the first electrode 31 and the stretched portions 342 and 344 extending from the side 322 of the second electrode 32, is thicker than the slit S2. .. Twice
このようにスリットＳＣ，ＳＤを太くすることで、横電極である第１電極３１と、縦電極である第２電極３２との、実質的な間隔が広くなって、並列の容量性を下げ、ピーク特性が変化することが期待できる。　 By making the slits SC and SD thicker in this way, the substantial distance between the first electrode 31 which is the horizontal electrode and the second electrode 32 which is the vertical electrode becomes wider, and the capacitance in parallel is lowered. It can be expected that the peak characteristics will change. Twice
図１６は、図１５のタッチパネル２３０Ａの構成を含んで疑似ディスプレイモジュールにした際の、Ｓ１１パラメータの周波数特性を示す図である。本測定では、タッチパネル２３０ＡのスリットＳＣ、ＳＤの太さは、２０μｍに設定し、他の寸法は、上述の疑似ディスプレイモジュールＳＤの寸法と同様である。　 FIG. 16 is a diagram showing the frequency characteristics of the S11 parameter when the pseudo display module includes the configuration of the touch panel 230A of FIG. In this measurement, the thicknesses of the slits SC and SD of the touch panel 230A are set to 20 μm, and the other dimensions are the same as the dimensions of the pseudo display module SD described above.

ここで、実際のオンセル金属細線層でのスリット間隔を調整する方法としては、図６に示す切断間隔Ｇを変化させることで達成される。例えば、浮遊導体を構成する外周における切断間隔と、スリットＳ１領域における切断間隔とが異なっていることが好ましい。　 Here, as a method of adjusting the slit interval in the actual on-cell metal thin wire layer, it is achieved by changing the cutting interval G shown in FIG. For example, it is preferable that the cutting interval on the outer periphery constituting the floating conductor and the cutting interval in the slit S1 region are different. Twice

In this configuration example, the length per side of the contours of the electrodes 31B and 32B is shorter than that in FIG. Comparing the size with the scale in the figure, the size per grid does not change, and while FIG. 10 is composed of nine grids per side including the invisible part, FIG. 17 Then, each side is composed of seven grids. In this way, the length of the side of the electrode is short, the periodic size is small, and the outer length of the geometric pattern is shortened, so that the position of the peak is shifted.

In this configuration example, the length per side of the contours of the electrodes 31C and 32C is even shorter than that in FIG. Twice
図中のスケールとの大きさを比較すると、格子１つあたりの大きさは変わらず、図１７は、見えない部分も含めて１辺あたり７つの格子で構成されるのに対し、図１９では、１辺あたり５つの格子で構成される。このように、電極３１，３２の辺の長さをさらに短く、周期サイズを小さく、ひし形の外形長を短くすることで、ピークをさらに高域へずらす。　 Comparing the size with the scale in the figure, the size per grid does not change, and while FIG. 17 is composed of seven grids per side including the invisible part, FIG. 19 shows. It is composed of 5 grids per side. In this way, the peaks are further shifted to higher frequencies by further shortening the side lengths of the electrodes 31 and 32, reducing the periodic size, and shortening the outer length of the rhombus. Twice

Sensor pattern and characteristics of the touch panel according to the fifth configuration example of the present invention) FIG. 21 is an enlarged view of the sensor pattern of the touch panel 230D according to the fifth configuration example of the present invention. The configuration shown in FIG. 21 is different from the configuration shown in FIG. 6 in that the jumper 35 is not provided. As a result, the skewer shape in the vertical direction is not connected to the portion where the jumper 35 is not provided, and the connection of the second electrode 32 is in a floating state.

In the waveform shown in FIG. 22, the position of the peak of horizontally polarized waves is almost the same as that of the waveform of FIG. 11, but the characteristics of vertically polarized waves are changed. Twice
詳しくは、ジャンパー３５を取り除くことで、抵抗が上がり、Ｙ軸でジャンパー３５を介して接続していた串型の同種の電極３２同士の電気的な接触において、導電接触ではなく、容量性の寄与が大きくなり、共振周波数を下げることになる。このようにすることで、ジャンパー３５を調整した方の偏波に対するピークを調整できる。　 Specifically, by removing the jumper 35, the resistance increases, and in the electrical contact between the skewer-shaped electrodes 32 of the same type that were connected via the jumper 35 on the Y axis, the contribution of capacitance rather than conductive contact Will increase and the resonance frequency will be lowered. By doing so, the peak for the polarization of the person who adjusted the jumper 35 can be adjusted. Twice
なお、図２１では、縦電極である第２電極３２を連結する交差部においてジャンパー３５を取り除くことで特性を変化させる例を説明したが、ジャンパー３５をなるべく太く（幅を広く、導体を厚く、本数を多く等）、接続することで、偏波の特性を変化させてもよい。　 In FIG. 21, an example in which the characteristics are changed by removing the jumper 35 at the intersection connecting the second electrode 32, which is a vertical electrode, has been described, but the jumper 35 is made as thick as possible (wide, thick conductor).

That is, the contour sizes of the electrodes 31 and 32 are the same, and the metal wires having the same line width are made denser. With this configuration, it can be expected that the peak characteristics will change by increasing the capacitance in parallel. In the case of this configuration, it is preferable to align the openings of the grids in the display panel 220 located below with the positions of the light emitting layers 25R, 25G, and 25B, and to provide the positions of the metal wires so as not to interfere with the light emission.

In this configuration, the materials of the insulating materials constituting the insulating protective layer 304E and the insulating hole 306E on the electrode layer 301 are different from the cross-sectional view of the touch panel 230 shown in FIG. Twice
一般的には、絶縁材として、ガラス、フィルム、アクリル等が用いられているが、本構成では、アクリルとは異なる誘電率を持った樹脂材料、例えば、ポリカーボネート樹脂やフッ素樹脂を含んだ材料で構成される。これにより、遮断域における電波の透過性を下げることができる。　 Generally, glass, film, acrylic, etc. are used as the insulating material, but in this configuration, a resin material having a dielectric constant different from that of acrylic, for example, a material containing a polycarbonate resin or a fluororesin is used.

Therefore, in the pseudo display module having the touch panel configuration shown in FIG. 23, the reflectance coefficient is -1 dB at any frequency of 24.2 to 29.5 GHz, 37.3 to 40 GHz, and 1.0 to 5.0 GHz.

そのため、このような構成のディスプレイモジュール３では、ディスプレイパネル２２０の最上層（表面）である陰極の部分を低抵抗にして、透明アンテナ１００に対して、良反射板として機能させると好適である。　 Therefore, in the display module 3 having such a configuration, it is preferable that the cathode portion, which is the uppermost layer (surface) of the display panel 220, has a low resistance so that the transparent antenna 100 functions as a good reflector. Twice
（５－１．一般的なOLEDディスプレイパネルの構成）　図２８は、一般的なディスプレイパネルの一例であるOLEDディスプレイパネル２２０の模式図である。図２８において、（ａ）は断面図であり、（ｂ）は平面図（上面図）である。　 (5-1. Configuration of a general OLED display panel) FIG. 28 is a schematic view of an OLED display panel 220 which is an example of a general display panel. In FIG. 28, (a) is a cross-sectional view, and (b) is a plan view (top view). Twice
図２８（ａ）に示すようにOLEDディスプレイパネル２２０は、基板２１、バックプレーン２２、下側反射電極２３、開口絶縁膜２４、発光層２５Ｒ，２５Ｇ，２５Ｂ、及び透明電極２６を備えている。基板２１は、例えばガ
ラスであって、バックプレーン２２は、ＴＦＴ（Thin Film Transistor）である。　 As shown in FIG. 28A, the OLED display panel 220 includes a substrate 21, a backplane 22, a lower reflective electrode 23, an aperture insulating film 24, light emitting layers 25R, 25G, 25B, and a transparent electrode 26. The substrate 21 is, for example, glass, and the backplane 22 is a TFT (Thin Film Transistor).
発光層２５Ｒ，２５Ｇ，２５Ｂは、積層薄膜で構成されており、下側反射電極２３、開口絶縁膜２４、発光層（積層薄膜）２５Ｒ，２５Ｇ，２５Ｂ、及び透明電極２６が、各色のOLED素子（organic light-emitting diode）２７Ｒ，２７Ｇ，２７Ｂとなる。　 The light emitting layers 25R, 25G, 25B are composed of a laminated thin film, and the lower reflective electrode 23, the aperture insulating film 24, the light emitting layer (laminated thin film) 25R, 25G, 25B, and the transparent electrode 26 are OLED elements of each color.

最も上側の透明電極２６は、Al或いはMgとAgの合金などの金属を光が透過する程度まで薄く構成したり、ITOなどの金属酸化物で構成されている。その為、抵抗が高く、図２７のように透明アンテナ１００を上部に接した時に、透明アンテナ１００に投入された電力を、透明電極２６で消費してしまう。この場合透明電極のシート抵抗は２～１００Ω/□となる。　 The uppermost transparent electrode 26 is made of a metal such as an alloy of Al or Mg and Ag thin enough to allow light to pass through, or is made of a metal oxide such as ITO. Therefore, the resistance is high, and when the transparent antenna 100 is brought into contact with the upper portion as shown in FIG. 27, the power input to the transparent antenna 100 is consumed by the transparent electrode 26. In this case, the sheet resistance of the transparent electrode is 2 to 100 Ω / □. Twice
一方で透明電極２６の金属を厚くすれば、低抵抗化できるが、今度はOLEDディスプレイパネル２２０のOLED素子２７Ｒ，２７Ｇ，２７Ｂからの光が透過しなくなってしまい、ディスプレイとして機能しなくなる。そこで、本発明では、透明電極２６の上側にパターン電極２８を設ける。　 On the other hand, if the metal of the transparent electrode 26 is made thicker, the resistance can be reduced, but this time, the light from the OLED elements 27R, 27G, 27B of the OLED display panel 220 will not be transmitted, and the display will not function. Therefore, in the present invention, the pattern electrode 28 is provided above the transparent electrode 26. Twice

本発明のOLEDディスプレイパネル２２０Ａの構成では、積層薄膜で構成される発光層２５Ｒ，２５Ｇ，２５Ｂの上部以外の部分に、低抵抗化のためにパターン電極２８を配置する。パターン電極２８は、抵抗が低くなるような材料・膜厚を選べば、どのような素材で構成されてもよく、具体的にはAl、Ag、AgとMgの合金、Cr、Ti、Cu、Au、ITO、SnO、ZnOなどの金属膜や酸化金属膜であっても良い。　 In the configuration of the OLED display panel 220A of the present invention, the pattern electrode 28 is arranged in a portion other than the upper portion of the light emitting layers 25R, 25G, and 25B composed of the laminated thin film in order to reduce the resistance. The pattern electrode 28 may be made of any material as long as the material and film thickness are selected so as to reduce the resistance. Specifically, Al, Ag, an alloy of Ag and Mg, Cr, Ti, Cu, It may be a metal film such as Au, ITO, SnO, ZnO, or a metal oxide film. Twice

パターン電極２８は、透明電極２６より比抵抗の小さい材料を用いて、透明電極２６の上であって、発光層２５Ｒ，２５Ｂ，２５Ｇの上部以外の部分にマスクパターン法又は他の成膜方法で成膜する方法の他に、透明電極２６の、発光層２５Ｒ，２５Ｇ，２５Ｂの上部以外の部分を、厚膜にすることで形成してもよい。　 The pattern electrode 28 is made of a material having a resistivity smaller than that of the transparent electrode 26, and is placed on the transparent electrode 26 by a mask pattern method or another film forming method on a portion other than the upper part of the light emitting layers 25R, 25B, 25G. In addition to the method of forming a film, the transparent electrode 26 may be formed by forming a thick film on a portion other than the upper portion of the light emitting layers 25R, 25G, and 25B.

この方法では、２つの異なる種類のマスクを組み合わせてパターン電極２８を形成する。例えば図３０（ａ）のような縦横に結線した第１のマスクＭ１と、図３０（ｂ）に示すような、斜めがけに結線した第２のマスクＭ２の２つのマスクを用いる。　 In this method, two different types of masks are combined to form the pattern electrode 28. For example, two masks, a first mask M1 connected vertically and horizontally as shown in FIG. 30 (a) and a second mask M2 connected diagonally as shown in FIG. 30 (b), are used. Twice
マスクを用いる方法では、１つのマスクだけでは、図２９（ｂ）のように、発光層２５Ｒ，２５Ｇ，２５Ｂの部分を点状に孤立させて残すパターンはマスク成膜できないので、２枚のマスクが必要となる。このように、形成するパターン電極２８の素材で形成された２枚のマスクを用いることで、一般的なOLEDディスプレイパネル２２０の透明電極２６上にパターン電極２８を構成できる。これにより、他の素材を使用せずに、孔が空いたマスク状のパターン電極２８を形成することができる。　 In the method using a mask, as shown in FIG. 29B, a pattern in which the light emitting layers 25R, 25G, and 25B are left isolated in dots cannot be formed with only one mask, so that two masks cannot be formed. Is required. By using the two masks formed of the material of the pattern electrode 28 to be formed in this way, the pattern electrode 28 can be formed on the transparent electrode 26 of the general OLED display panel 220. As a result, the mask-shaped pattern electrode 28 with holes can be formed without using any other material. Twice

At the time of film formation of the electrode material, the pattern electrode 28 is formed in a portion other than the material pattern R that repels the pattern electrode material. Twice

Since these fluorine materials or nucleation-inhibiting coatings transmit light, they do not affect the display function of the lower OLED display panel 220. Twice
この手法だと、フッ素材料又は核形成阻害コーティングによって発光層２５Ｒ，２５Ｇ，２５Ｂをカバーしながら、カバーされていない部分にパターン電極２８を成膜するため、パターン電極２８のアライメント精度が上がる。またパターン電極２８の厚さはどこでも同じになる。　 In this method, the pattern electrode 28 is formed on the uncovered portion while the light emitting layers 25R, 25G, and 25B are covered by the fluorine material or the nucleation-inhibiting coating, so that the alignment accuracy of the pattern electrode 28 is improved. Further, the thickness of the pattern electrode 28 is the same everywhere. Twice

具体的には、パターン電極を含む上部電極のシート抵抗は、2Ω/□より小さくなる。良反射板としては、1Ω/□以下が望ましく、0.5Ω/□が更に望ましい。そのため、パターン電極を含むディスプレイパネル２２０Ａは、上の透明アンテナ１００を含むディスプレイモジュール３の状態では、電磁波の反射振幅＞透過振幅となり、反射係数Ｓ１１が-1dB以上になる。　 Specifically, the sheet resistance of the upper electrode including the pattern electrode is smaller than 2Ω / □. As a good reflector, 1Ω / □ or less is desirable, and 0.5Ω / □ is even more desirable.

タッチパネル４００では、図３４（ａ）に示す基本構成は、図４に示す下側に設けられるタッチパネルの基本構成と同様であるが、各電極４１，４２の構造が、電波の透過に適した構成になっている。　 In the touch panel 400, the basic configuration shown in FIG. 34 (a) is the same as the basic configuration of the touch panel provided on the lower side shown in FIG. 4, but the structures of the electrodes 41 and 42 are suitable for transmitting radio waves. It has become. Twice
例えば、図３４（ｂ）に示す電極４１では、格子が外側のみ形成され、中央部には格子が設けられていない。図３４（ｃ）に示す電極４１Ａでは、輪郭内の格子において、交点以外の部分が切断され、不連続となっている。なお、（ｂ）、（ｃ）以外にも様々な組み合わせが考えられる。例えば（ｂ）の中央部に（ｃ）のような不連続な配線を設けてもよく、（ｂ）の一部を切断してもよい。但し、上端と下端が電気的に接続されている必要がある。また電極４２の場合には、右端と左端が電気的に接続されている必要がある。　 For example, in the electrode 41 shown in FIG. 34 (b), a grid is formed only on the outside, and no grid is provided at the center. In the electrode 41A shown in FIG. 34 (c), a portion other than the intersection is cut off in the grid in the contour, resulting in discontinuity. In addition to (b) and (c), various combinations can be considered. For example, a discontinuous wiring as in (c) may be provided in the central portion of (b), or a part of (b) may be cut off. However, the upper end and the lower end must be electrically connected. Further, in the case of the electrode 42, the right end and the left end need to be electrically connected. Twice
図３５は、透明アンテナの上側に設けられるタッチパネルの電極の他の構成例である。電極４１は、格子をベースとしない形状であってもよいが、上端と下端が電気的に接続されている必要がある。また電極４２の場合は、右端と左端が電気的に接続されている必要がある。　 FIG. 35 is another configuration example of the electrodes of the touch panel provided on the upper side of the transparent antenna. The electrode 41 may have a shape that is not based on a grid, but the upper end and the lower end need to be electrically connected. Further, in the case of the electrode 42, the right end and the left end need to be electrically connected. Twice
図３５（ａ）に示す電極４１Ｂでは、同一電極との接続方向に対して折れ曲がるような線を三重に設けた三重枠構造となっている。図３５（ｂ）に示す電極４１Ｃでは、ひし形の中に、長方形のスリットを設ける構造となっている。　 The electrode 41B shown in FIG. 35 (a) has a triple frame structure in which lines that bend with respect to the connection direction with the same electrode are provided in triplicate. The electrode 41C shown in FIG. 35B has a structure in which a rectangular slit is provided in the rhombus. Twice
図３５（ｃ）に示す電極４１Ｄでは、枠部の一部を欠いた、略Ｃの字の外形となるような枠線によって構成されている。図３５（ｄ）に示す電極４１Ｅでは、線が曲線状に一筆書きに蛇行する形状であって、外形が略四角形になるように構成されている。図３５（ｅ）に示す電極４１Ｆでは、線がジグザグ状に一筆書きに蛇行する形状であって、外形が略四角形になるように構成されている。　 The electrode 41D shown in FIG. 35 (c) is configured by a frame line having a substantially C-shaped outer shape, lacking a part of the frame portion. The electrode 41E shown in FIG. 35 (d) has a curved line that meanders in a single stroke, and is configured to have a substantially quadrangular outer shape. The electrode 41F shown in FIG. 35 (e) has a zigzag shape in which the lines meander in a single stroke, and is configured to have a substantially quadrangular outer shape. Twice
その他、電極を構成する四角形を小さくしてもよい。なお、いずれの電極４１～４１Ｆの構成においても、電極４１の枠や線を構成する金属ワイヤーが、下層のディスプレイパネル２２０からの発光を妨害しないように、発光層２５Ｒ，２５Ｇ，２５Ｂの真上を避けて、金属ワイヤーを設ける。　 In addition, the quadrangle constituting the electrode may be made smaller. In any of the configurations of the electrodes 41 to 41F, directly above the light emitting layers 25R, 25G, and 25B so that the metal wires constituting the frames and wires of the electrodes 41 do not interfere with the light emission from the lower display panel 220. Provide a metal wire to avoid. Twice
図３４、図３５のように構成された、タッチパネルは、格子状の金属細線で四角形状に全面に電極が形成される図５の構成よりも、金属細線の部分が少なく、疎な構成となる。例えば、電極における金属細線が占める割合は１０％未満である。　 The touch panel configured as shown in FIGS. 34 and 35 has a sparser structure with fewer metal thin lines than the configuration of FIG. 5 in which electrodes are formed on the entire surface in a quadrangular shape with grid-shaped metal fine lines. .. For example, the proportion of thin metal wires in the electrodes is less than 10%. Twice
このような電極を含んで構成されるタッチパネル４００は、アンテナの使用周波数で、電磁波の反射振幅＜透過振幅である「良透過板」として機能する。　 The touch panel 400 including such electrodes functions as a "good transmission plate" in which the reflection amplitude of the electromagnetic wave is less than the transmission amplitude at the frequency used by the antenna. Twice
なお、図３４、図３５の電極４１～４１Ｆでは電極の外観の概略図を示しているが、これらの線状又は枠状、又は塗りつぶし形状の電極の導体部分は、図６に示すように梯子状の金属細線Ｗによって形成されていてもよい。その場合、図６のように、金属細線の一部を切断することで、電極４１～４１Ｆのような導通構造を作成することができる。この場合、電極４１～４１Ｆの構造の周囲に、図６でＦと図示した浮遊導体が残る場合があるが、これは現在着目している電波の透過性には影響しない。したがって、浮遊導体はあっても無くてもよい。　 Although the electrodes 41 to 41F of FIGS. 34 and 35 show a schematic view of the appearance of the electrodes, the conductor portion of these linear, frame-shaped, or filled-shaped electrodes is a ladder as shown in FIG. It may be formed by a thin metal wire W. In that case, as shown in FIG. 6, a conductive structure such as the electrodes 41 to 41F can be created by cutting a part of the thin metal wire. In this case, the floating conductor shown as F in FIG. 6 may remain around the structure of the electrodes 41 to 41F, but this does not affect the transparency of the radio wave currently being focused on. Therefore, the floating conductor may or may not be present. Twice
なお、図３２では、良透過板となるタッチパネル４００は、透明アンテナ１００の上側に設けられる例を説明したが、タッチパネル４００は、
透明アンテナと同一面上に設けられてもよい。　 In FIG. 32, an example in which the touch panel 400 serving as a good transmissive plate is provided on the upper side of the transparent antenna 100 has been described, but the touch panel 400 is
It may be provided on the same surface as the transparent antenna.
あるいは、良透過板となるタッチパネル４００は、図２６に示すような、良反射板となるディスプレイパネル２２０Ａの上側であって、透明アンテナ１００の下側に設けられてもよい。疎の構成のタッチパネル４００は、ディスプレイパネル２２０Ａによって反射した電波が透過して邪魔をしないためである。　 Alternatively, the touch panel 400 serving as a good transmissive plate may be provided above the display panel 220A serving as a good reflecting plate and below the transparent antenna 100 as shown in FIG. 26. This is because the touch panel 400 having a sparse configuration allows radio waves reflected by the display panel 220A to be transmitted and does not interfere with the touch panel 400. Twice
また、本発明の透明アンテナは、１つでも送受信可能であるが、より特性を高めるために、複数の透明アンテナを集めたアレイ状態（アンテナアレイ）で配置されてもよい。　 Further, although one transparent antenna of the present invention can transmit and receive, in order to further enhance the characteristics, it may be arranged in an array state (antenna array) in which a plurality of transparent antennas are collected. Twice
以上、本発明の例示的な実施の形態の透明アンテナについて説明したが、本発明は、具体的に開示された実施の形態に限定されるものではなく、特許請求の範囲から逸脱することなく、種々の変形や変更が可能である。 Although the transparent antenna of the exemplary embodiment of the present invention has been described above, the present invention is not limited to the specifically disclosed embodiment and does not deviate from the scope of claims. Various modifications and changes are possible.
