The upper electrode sheet 108 is disposed under the transparent resin film and has a rectangular shape. The upper transparent electrode 106a and the upper portion circuit 106b provided around the upper transparent electrode 106a are formed by forming a gap between the lower electrode sheet 108 and the electrodes 106a and 108a; and the decorative sheet 104 is attached to the transparent resin film. At least one of the surfaces of the upper electrode pad 106a is formed by concealing the lower circuit 108b and the upper circuit 106b to form a decorative layer of the transparent window portion 104a (see FIG. 24). The panel embedding portion 122 held by the front outer casing 119 is embedded without gaps so that the outer surface thereof forms the same plane as the circumference, and the protection can pass through the transparent window portion Identification disposed from the external display device 120 of the lower side thereof (refer to FIGS. 25 and 26 of FIG.). In the protective panel 101 having the touch input function configured in this manner, when the outer surface is pressed by a finger or a pen, the upper electrode sheet 106 and the decorative sheet 104 are further bonded as needed. The hard coat film 102 on the upper surface of the decorative sheet 104 is integrally bent downward by the pressing point (hereinafter, the laminated body is referred to as a movable sheet), and as a result, the upper electrode sheet 106 and the upper electrode sheet 106 are formed. The two transparent electrodes 106a, 108a on the inner surface of the lower electrode sheet 108 are in contact, whereby the input position is detected. Fig. 26 is a cross-sectional view showing an example of a configuration of a front outer casing of the protective panel 101 with a touch input function. As shown in Fig. 26, the front outer casing 119 is provided with a panel embedding portion 122 for embedding the protective panel 101 with a touch input function. The panel embedding portion 122a is configured to have a thickness substantially equal to the thickness of the protective panel 201107831 101 with the touch input function described above, and a seamless configuration in which the outer surfaces of the protective panel 101 form the same plane can be obtained. Further, an opening or a recess 123 is formed on the surface of the panel embedding portion, which is slightly smaller than the bottom surface, and the peripheral edge 122a of the bottom surface of the display device that can be externally recognized through the transparent window portion supports the touch input function. 101 and fixed by an adhesive or double-sided tape 124. The protective panel of the electronic device display window configured in this manner can perform touch input on the liquid crystal display screen, and the outer surface and the front outer surface on the outer surface of the protective bright window portion 104a and the periphery 104b of the transparent window portion 104a.

PRIOR ART DOCUMENT Patent Document Patent Document 1: International Publication No. 2005/ 06445 No. 1 hand f [Explanation] The problem to be solved by the invention However, the problem of the above protective panel described in Patent Document 1 is as follows. That is, the electronic device such as a mobile phone or a smart phone equipped with the protective panel slot structure with the touch input function is provided, and the outer surface of the window portion 104a is often exposed to include the outer surface of the periphery 104b. All front of the protection panel. Therefore, the load generated by the point of the nib or the like grasps the surface of the electronic machine and the bottom of the circumference 122 by hand for the arrangement 120. In the protective panel 101, the cover portion of the panel does not produce 1 0 4 a. The design of the system. 1 (Hey, there is 101 that is not only through the non-fingertips or 130 of the decorative part, or the 201107831 electronic machine 130 is placed in the pocket of the trousers, while the protective panel ιοί covers the overall load before the strong load, There is a case where the function or the appearance is deteriorated. The specific reason is as follows. The paste layer 107 is used for the upper electrode sheet 106 and the lower electrode sheet 108, and the upper electrode is formed so as to avoid the transparent window portion 104a. The respective electrodes 106a, 108a of the sheet 106 and the lower electrode sheet 1 8 can be electrically connected to each other. However, a gap formed between the upper electrode sheet 106 and the electrodes 106a, 10 8a of the lower electrode sheet 108 (hereinafter, referred to as "cell" The internal pressure of the cell 112 rises, so that the air enclosed in the cell 112 is extruded to the outside from the weakest point of the paste layer 107. Then, the movable piece 115 after the air is leaked is even under load. After being released, the gap between the electrodes 106a and 108a is always kept small, and it is impossible to return to the original state, resulting in malfunctions such as appearance defects such as Newton's rings or poor insulation. The object of the present invention is to provide a protective panel with a touch input function of an electronic device display window, which does not cause malfunction or appearance defects even when a strong load is applied to the entire outer surface.

Advantageous Effects of Invention According to the present invention, a multi-column space (hereinafter, simply referred to as a multi-column space) which is expanded under a decorative portion other than the transparent window portion is provided by patterning of the paste layer, thereby covering the front surface of the protective panel When a strong load is applied as a whole, even if the volume of the cell is reduced under the transparent window portion, the increase in the internal gas pressure can be suppressed by the conventional technique. Even if the entire window is covered with a load, the air in the cell preferentially squeezes between the frame portion and the upper or lower electrode sheet, and moves to the adjacent multi-column space. Further, it is assumed that the air in the cell reaches the frame portion even though it passes through the multi-column space, and can be offset by splitting in the multi-column space (refer to Fig. 22) or by repeating the splitting and converging (see Fig. 23). momentum. On the other hand, when a strong load is applied to the entire front surface of the protective panel, it is formed in an island shape by a plurality of columnar spaces which are firmly fixed by a plurality of island portions constituting the paste layer under the decorative portion. The volume of the space between the parts does not change. That is, dents are not left in the decorative portion in front of the protective panel. Therefore, even if a strong load is applied to the entire outer surface, the occurrence of malfunction or appearance defects can be suppressed.

又，在多柱空間13,必需使成爲各柱之島狀部7a分散 配置而無不均。其原因在於，若在柱之配置有疏密之不均， 則在密的部分難以接受胞元12內之空氣，反之在疏的部分 會於前述上部電極片6產生撓曲等，而成爲加飾部4b上之 外表面的外觀不良。多柱空間13係藉由涵蓋除了該透明窗 部4a以外之廣區域設置於該框狀部7b之內側，而能只以 糊層7收納胞元12內之空氣，那部分以分散之柱支撐而不

之點上，則島狀部7a之形成面積變大的筋狀圖案係較爲有 利。此外，就點之外形形狀而言，例如除了圓形（參照第4 圖至第7圖）以外，亦可形成爲四角形（參照第8圖及第9 圖）、三角形（參照第10圖）、六角形（參照第11圖）、十字 形（參照第12圖及第13圖）。 -17- 201107831 又’多數個島狀部7 a係分散配置以構成多柱空間】3， 就其配置圖案而言，例如，在點狀之島狀部7 a的情況下，

此外’島狀部7a之大小係以將直徑或粗細設爲〇.5mm 〜3mm ’將前述島狀部彼此之間隔設爲1 mm〜5 mm較佳。 前述島狀部7a之直徑或粗細若未達〇.5mm，則無法牢 固地固定於前述上部電極片6及前述下部電極片8之兩 方，若超過3mm則無祛配置多數個前述島狀部7a。 此外，前述島狀部7a彼此之間隔若未達1 mm，則變 得難以收納胞元12內之空氣，若超過5 mm則於前述上部 電極片6變得容易產生撓曲等。 又，前述糊層7亦可著色成黑色。若以此方式構成， 則有可使其具有遮光功能的優點。詳細而言，附有觸控輸 入功能之保護面板1，雖係配置於顯示裝置之前面並嵌入 外飾框體，不過已設想到來自顯示裝置之光會透過多柱空 間1 3無謂地洩漏的情況。因此，藉由將前述糊層7著色成 黑色，即可抑制經由多柱空間1 3漏光。欲將前述糊層7著 -18- 201107831

The protective panel 1 with a touch input function of the electronic device display window shown in FIGS. 1 and 2 is provided with a protective panel body 10, a lower electrode sheet 8, an upper electrode sheet 6, a decorative sheet 4, and a paste layer. 7 and hard coat film 2. The lower electrode sheet 8 is attached to the upper surface of the transparent resin film, and has a rectangular lower transparent electrode 8a and a lower portion of the circuit 8b disposed around the lower transparent electrode 8a, and is bonded to the PSA (Pressure Sensitive Adhesive) 9 The foregoing protects the upper surface of the panel body 10. The upper electrode sheet 6 is disposed on the lower surface of the transparent resin film, and has a rectangular upper transparent electrode 6a and an upper portion circuit 6b provided around the upper transparent electrode 6a, and a gap is formed between the lower electrode sheet 8 and the electrodes 6a, 8a. The paste layer 7 is followed. The decorative sheet 4 is formed on at least one surface of the transparent resin film, and has a decorative layer 41 that forms the transparent window portion 4a by concealing the lower circuit 8b and the upper circuit 6b, and is bonded to the upper electrode sheet 6 by PSA5. Above. Further, on the surface of the decorative sheet 4, the hard coat film 2 can be bonded to the surface of the decorative sheet 4 by PSA3. The paste layer 7 is followed by the upper electrode sheet 6 and the lower electrode sheet 8, and is formed by the frame-like portion 7b provided along the outer periphery thereof and the transparent portion 4a and the circuit portions 6b and 8b. A plurality of island portions 7a disposed inside the frame portion 7b are dispersed. The protective panel 1 of the electronic device display window is configured to be embedded in the panel embedding portion 122 held by the front exterior frame 119 without gaps so that the outer surface of the outer-11-201107831 is formed in the same plane as the surroundings, and is protected. The display device 120 is disposed on the lower side of the transparent window portion 4a from the outside. When the outermost surface is pressed by a finger or a pen, the upper electrode sheet 6 and the decorative sheet 4 are integrally bent and bent downward, and as a result, they are formed on the inner surfaces of the upper electrode sheet 6 and the lower electrode sheet 8. The electrodes 6a, 8a are in contact with each other, whereby the input position is detected. The material of the transparent plate used for the protective panel main body 10 is a material which is excellent in transparency and can protect the display device 15 such as a liquid crystal panel or an organic EL panel from damage. For example, the material of the transparent plate may be glass, a polystyrene resin, a polyolefin resin, an ABS resin, an AS resin, an acrylic resin, or a general-purpose resin such as an AN resin. Further, as the material of the transparent plate, a polyphenylene ether/polystyrene resin, a polycarbonate resin, a polyacetal resin, a polycarbonate modified polyphenylene ether resin, or a polyterephthalic acid can be used. General purpose engineering resin such as butadiene ester resin or ultrahigh molecular weight polyethylene resin, or polyfluorene resin, polyphenylene sulfide resin, polyphenylene ether resin, polyarylate resin, polyether sulfimide resin, polyphthalamide A super engineering resin such as an amine resin, a liquid crystal polyester resin, or a polyallyl heat resistant resin. In particular, in terms of market trends, the demand for thin products is strong, and it is preferable to use thin and hard glass as the material of the transparent plate. For the material of the transparent resin film used for the lower electrode sheet 8 and the upper electrode sheet 6, it is possible to use engineering plastics such as polycarbonate, polyamide or polyether ketone, acrylic or poly pairs. Ethylene phthalate-12-201107831, a resin film such as polybutylene terephthalate or the like. The lower transparent electrode 8a and the upper transparent electrode transparent conductive film are formed. The material of the transparent conductive film is tin, indium oxide, antimony oxide, zinc oxide, cadmium oxide, or a film of an oxide, or gold, silver, copper, tin, nickel, aluminum, or a conductive polymer. In the method of forming the lower transparent electrode portion transparent electrode 6a, for example, a conductive film is formed on the through surface by using true sputtering, ion plating, CVD, or roll coating, and then removed by etching. Engraving the portion of the electrode to be left as an electrode, immersing in an etching solution such as hydrochloric acid or the like, or spraying a conductive film on a portion where the resist is not formed, by lithography or a resisting agent, and then by blocking the photoresist It is removed by swelling or dissolution. Further, etching of an electrical film can also be utilized. The lower circuit 8b and the upper circuit 6b are formed by a predetermined pattern such as a bar or a wire. Further, as the material of the first 8b and the upper circuit 6b, a metal such as gold or nickel or a conductive paste such as carbon is used. In terms of the method, the printing method such as screen printing, lithography, gravure printing, or the photoresist method, or the brush coating method is equal to the formation of the touch panel by the lower circuit 8b and the upper circuit 6b. Framed. The reason for this is that the protective body is disposed in the electronic device 6 such as a mobile phone, and the liquid 6a is made of a metal such as oxidized ITO or the like, 8a, and the above-described upper vapor deposition method or the bright resin film. section. The etched screen etching method is used to remove the immersion in the solvent laser to conduct the busbars (bus, the lower circuit, silver, copper, or their forming brushes, or bombs. In addition, the 'off' does not need to be a panel 1 The front front decorative frame 13 of the crystal display window is not limited by the size of the display device 15. The paste layer 7 can be used to form the frame portion 7b and the plurality of frames. An insulating PSA composed of an acrylic resin, an epoxy resin, a phenol resin, a vinyl resin or the like, which is patterned in the form of an island portion 7a, wherein the frame portion 7b is along the upper electrode sheet 6 and the lower electrode sheet 8 outer periphery' The island portion 7a is disposed inside the frame portion 7b while avoiding the transparent window portion 4a and extending to the circuit portions 6b and 8b. Further, the paste layer 7 can use a screen. A normal printing method such as printing, lithography, gravure printing, or elastic printing is formed on the upper electrode sheet 6 or the lower electrode sheet 8. Alternatively, a paste layer may be temporarily formed on a separator by the aforementioned method. After 7, then The upper electrode sheet 6 or the lower electrode sheet 8 is bonded to the surface and then transferred to the separator. The paste layer 7 is patterned to be expanded under the decorative portion 4b other than the transparent window portion 4a. In the multi-column space 13 (refer to Fig. 3), when a strong load is applied to the entire front surface of the protective panel 1, the volume of the cell 12 can be suppressed in the cell 12 even under the transparent window portion 4a. The increase in the air pressure is because the air in the cell 12 is preferentially moved between the frame portion 7b and the upper or lower electrode sheets 6, 8 even if a load is applied to the entire transparent window portion 4a. In addition, it is assumed that the air in the cell 12 reaches the frame portion 7b through the multi-column space 1 3, and is shunted in the multi-column space 13 (refer to FIG. 22), or Splitting and merging (refer to Fig. 23) can also offset the momentum. -14- 201107831 On the other hand, when a strong load is applied to the front surface of the protective panel 1, it is formed by the decorative part 4b. The plurality of island portions 7a of the paste layer 7 are firmly adhered to the fixed multi-column space 13, The volume of the space formed between the portions 7a does not change. That is, the dents are not left in the decorative portion 4b in front of the panel 1. Thus, since the circuit 6b is also expanded, the portion 8b is broadly island-shaped. As described above, the volume of the multi-column space 13 does not change, so that the multi-column 13 also has sufficient margin to receive the air that has moved from the cell 12 under the transparent window portion 4a. Therefore, it is enclosed in the cell 12. The air does not leak from the weakest point of 7 to the outside and becomes unreturnable. That is, after the negative division, the gap between the electrodes 6a, 8a is restored without causing poor appearance or poor insulation of cattle. The function is poor. However, the following describes how the internal air pressure is affected if the volume of the space formed between the island portions 7a is constant when a strong load is applied to the entire protective panel 1. Fig. 19(a) shows a state in which a touch input function panel is attached to a prior art before a load is applied, and a frame-like paste layer 107 constitutes a cell 1 1 having substantially the same size of the window portion 104a. 2. In this state, the volume of the cell is V, and the internal pressure is P. . After a strong load is applied to the front, as shown in Fig. 19(b), the volume of the cell 112 is reduced to the internal pressure, and then rises to P, = (VJV1,) P. . As shown in Fig. 20(a), even before the load is applied, even if the volume of 112 is enlarged larger than the transparent window portion i4a, it cannot be solved. The whole number of island-shaped protections 7a, when the space is moved by the paste layer, the front of the ring is i, the guarantee and the penetration: 112 the whole V'l > the cell is, 12 201107831 before the load is applied, the cell 1 12 The volume system v2 = V, + (5 v2 internal pressure system P. After a strong load is applied to the front unit, as shown in Fig. (b), the volume of the cell 112 is reduced to VS, and the internal pressure is { = (V2/V'2) P. V, the same degree as VS, and the previous V2 = V | + V2 - the internal pressure becomes P2# ((Vi + δν2) / ( ν, ι) In contrast, the present invention has a cell 12 and a multi-column space 13 in a state before the load is applied, as shown in Fig. 21(a). The total volume V3 = Vi + < 5V3' internal air pressure system P. After a strong load is applied to the front body, as shown in Fig. 12(b), the volume of the cell 12 is reduced to v, but the multi-column The volume of the space 13 does not shrink. That is, VS = V, + V3. Therefore, the internal air pressure becomes P3 = (VWV '3) P 〇 = ((Vi + ν3) / (VS + 5V3)) Pd. Since VS>>V, The internal pressure of the Pi of the prior art can be solved. Further, in the multi-column space 13, it is necessary to firmly fix the upper electrode sheet 6 and the front lower electrode by the adhesive force provided in the island portion of each column. The reason for this is that if the column is simply stored between the upper electrode sheet 6 and the lower electrode sheet 8, when a strong load is applied to the front surface of the viscous protection panel 1, a large amount is generated. The column 13 is split and the air does not move, or the split and merge flow but the air moves. That is, the air in the cell 12 pushes the space between the columns of the multi-column 13 and the upper electrode sheet 6, and In one state, the frame shape 7b' is extruded to the outside of the frame portion 7b, or the cell 12 is P: 5 > plus the whole 1' δ ά is 7a, which is described in the air of the 201107831 air. The bottom of each column of the multi-column space 13 is pushed away from the lower electrode sheet 8 to reach the frame-like portion 7b, and is extruded outside the frame-like portion 7b in this state. Further, in the multi-column space 13 It is necessary to disperse the islands 7a which are the columns, and it is necessary to disperse The reason is that if there is unevenness in the arrangement of the pillars, it is difficult to receive the air in the cells 12 in the dense portion, and in the sparse portion, the upper electrode sheets 6 may be deflected or the like. The outer surface of the decorative portion 4b is defective in appearance. The multi-column space 13 is provided on the inner side of the frame portion 7b in a wide area other than the transparent window portion 4a, and can be accommodated only in the paste layer 7. The air in the element 12, which is supported by the dispersed column without causing the deflection of the upper electrode sheet 6, constitutes a plurality of island portions 7a of the multi-column space 13, and the pattern may be in the form of dots or punctual. Although it may be a ribbed pattern, if it is a dot-like or quasi-dot pattern, the formation area of the island portion 7a may be small. Conversely, more volume of the multi-column space 13 can be obtained. Further, in the case of a dot-like or quasi-point pattern, since the flow of air can be not only shunted, but also the splitting and joining can be repeated, it is easy to eliminate the momentum when reaching the frame portion 7b. However, at the point of the adhesion force, the rib-like pattern in which the formation area of the island portion 7a becomes large is advantageous. Further, the shape of the point outer shape may be formed into a quadrangular shape (see FIGS. 8 and 9) and a triangle (see FIG. 10) in addition to a circular shape (see FIGS. 4 to 7). Hexagon (see Figure 11) and cross (see Figures 12 and 13). -17- 201107831 Further, 'a plurality of islands 7a are arranged in a distributed manner to form a multi-column space.' 3, and in the case of the arrangement pattern, for example, in the case of the dot-like island portion 7a, it can be formed as a positive Square arrangement (refer to Fig. 4, Fig. 8 and Fig. 12), triangular lattice arrangement (refer to Fig. 5, Fig. 9, Fig. 11 and Fig. 13), honeycomb frame configuration (refer to Fig. 6, Fig. 7 and 1) and so on. Further, in the case of the rib-shaped island portion 7a, in addition to the vertical stripes (see Fig. 14), it may be formed as a horizontal stripe (see Fig. 16) and vertical and horizontal (see Fig. 6). Wait. Further, as shown in Fig. 17, one end of the stripe may be connected to the frame portion 7b. Further, the size of the island portion 7a is preferably set to have a diameter or a thickness of 〇.5 mm to 3 mm'. The interval between the island portions is preferably 1 mm to 5 mm. When the diameter or thickness of the island-shaped portion 7a is less than 5 mm, it cannot be firmly fixed to both the upper electrode sheet 6 and the lower electrode sheet 8, and if it exceeds 3 mm, a plurality of the island portions are not disposed. 7a. Further, when the distance between the island-like portions 7a is less than 1 mm, it is difficult to accommodate the air in the cells 12, and if it exceeds 5 mm, the upper electrode sheet 6 is likely to be deflected or the like. Further, the paste layer 7 may be colored black. If it is constructed in this way, there is an advantage that it can have a light blocking function. Specifically, the protective panel 1 with the touch input function is disposed in front of the display device and embedded in the exterior frame, but it is assumed that light from the display device will unnecessarily leak through the multi-column space 1 3 . Happening. Therefore, by coloring the paste layer 7 to black, light leakage through the multi-column space 13 can be suppressed. It is preferable that the paste layer 7 is colored black -18-201107831 as long as it contains a suitable color or dye as a colorant in the paste layer 7. Further, the lower electrode sheet 8 and the upper electrode sheet 6 are provided with spacers 11 so as not to be in erroneous contact with the opposing faces 6a, 8a provided. In the case of the spacer 11, the translucent resin can be formed into a fine dot shape by a photo-process. Further, a plurality of fine points are formed by the printing method, and the material of the transparent resin cover film used for the decorative sheet 4 can be used as the spacer 11. A polycarbonate type, a polyamide type, a polyether ketone type, etc. can be used. A resin film, an acrylic resin film, a polyethylene terephthalate resin film, or a polybutylene terephthalate resin film. The decorative sheet 4 is formed on at least one of the transparent resin cover films to form a decorative layer 41 having a transparent window portion 4a, and is bonded to the upper surface of the upper sheet 6. Since the lower electrode sheets 8 and the electrode sheets 6 are provided with opaque circuits 8b, 6b as described above, they are covered and covered. The portion covered with the decorative layer 41 is a decorative portion. The portion covered with the decorative layer 41 serves as a transparent window portion 4a. The decorative layer 41 is typically formed with a printed layer on the protective panel. The material may be a polyvinyl chloride resin, a polyamide resin resin, a polyacryl resin, a polyurethane resin, an acetal resin, or a polyester polyurethane resin. A resin such as a cellulose ester male or an alkyd resin is a binder, and a colored ink containing a suitable color or dye as a coloring agent is used. In the case of the method of forming the printed layer, the light of the two lights, or the surface of the plastic ester, may be 4b, the unprinted layer, the polyester polyethylene resin For the pigment, -19-201107831 can be used in a usual printing method such as lithography, gravure printing, or screen printing. In particular, a lithographic or gravure printing method is suitable for multicolor printing or gray scale rendering. Further, in the case of a single color, a coating method such as a gravure printing method, a roll coating method, or a knife coating method may be employed. Further, the decorative layer 41 may be composed of a metal thin film layer or a combination of a printed layer and a metal thin film layer. The metal thin film layer is used as the decorative layer 41 for expressing metallic luster, and can be formed by a vacuum deposition method, a sputtering method, an ion plating method, a gold plating method, or the like. At this time, depending on the metallic luster color to be expressed, metals such as aluminum, nickel, gold, platinum, chromium 'iron, copper, tin, indium, silver, titanium, lead, and zinc, or alloys thereof, or they may be used. The metal film layer is usually formed locally. Further, when the metal thin film layer is provided, a front anchor layer or a rear anchor layer may be provided in order to improve adhesion to other layers. Further, the decorative layer 41 may be formed on either side of the transparent resin cover film, and when it is formed on the lower surface as an example, and is bonded to the upper surface of the upper electrode sheet 6, the hard coat film 2 may not be bonded. The decorative layer 4 1 can also be protected from abrasion caused by fingers or pens. Further, after the protective panel main body 10 and the lower electrode sheet 8, the upper electrode sheet 6 and the decorative sheet 4, and the decorative sheet 4 and the hard coating film 2 are used, Insulating PSA9 composed of an acrylic resin, an epoxy resin, a phenol resin, or a vinyl resin, 5, -20 - 201107831 Further, the connection between the lower circuit 8b and the upper circuit 6b and an external device (not shown) may be, for example, The lower circuit 8b and the upper circuit 6b are extended to a connection portion provided at an edge portion of the upper electrode sheet 6 to be integrated at one portion, and the terminal portions 6c, 8c corresponding to the connection portion are formed in the protective panel body 10 A through hole (not shown) of the laminated body of the lower electrode sheet 8 is connected to the FPC (flexible printed wiring board) from the back surface of the protective panel main body 10. In the case of the FPC, the electric signal can be taken out from the through hole, but it is more preferable to provide a pin-attached FPC with four metal pins on the connection side end portion of the FPC in a vertical direction corresponding to the through hole. Furthermore, in the method of removing the electrical signal, in addition to being removed from the back surface of the protective panel body 10, as in the conventional touch panel, between the upper electrode sheet 6 and the lower electrode sheet 8 The commercially available FPC is inserted from the side and output to the outside. The thickness of the upper electrode sheet 6 and the decorative sheet 4 and the hard coat film 2 as needed is usually 0.3 mm to 0.8 mm. Further, the thickness of the lower electrode sheet 8 is usually 0.05 mm to 0.25 mm. Further, the protective panel main body 10 is usually a thickness of 0.4 mm to 1.0 mm. Although the protective panel 1 with the touch input function of the electronic device display window of the present invention has been described above, the protective panel 1 is assembled in the same manner as the conventional technique (see FIGS. 25 and 13). The electronic device is embedded in the panel embedding portion 122 held by the front outer casing Π 9 without any gap so that the outer surface of the protective panel 1 forms the same plane as the periphery. 201107831 The protective panel 1 assembled in the electronic device in this manner, because the touch input can be performed on the liquid crystal display screen, and the outer surface of the transparent window portion 4a of the protective panel 1 and the decorative portion around the transparent window portion 4a There is no step between the outer surface of the upper surface 4b and the outer surface of the front outer frame 119, so that the transparent window portion 4a is felt to be integrated into the front outer frame 119. Moreover, when the electronic device is grasped by hand, or the electronic device is seated behind the pocket of the trousers, even if a strong load is applied to the entire front surface of the protective panel 1, as described above, even if a strong load is applied to the front as a whole, There is a malfunction or a poor appearance. [Example 1] First, a glass plate having a thickness of 0.5 mm was used to obtain a protective panel body having a length of 80 mm and a width of 50 mm. Further, on one surface of a transparent insulating film made of a polycarbonate (PC) film having a thickness of 0.1 mm, an ITO film having a thickness of 20 nm was formed on the entire surface by sputtering, and an ITO film of an unnecessary portion was etched and removed by etching. Thereby, a transparent electrode having a rectangular lower portion is formed. Next, on the entire lower transparent electrode, an epoxy acrylate-based thermosetting resin was used to form a fine dot-like spacer by screen printing. Further, the silver paste is screen-printed to form a lower bus bar disposed on both sides opposite to the longitudinal direction of the lower transparent electrode and a pull-up wire for outputting from the lower bus bar to the outside, respectively, as the lower electrode ; road, and made a vertical 80mm x 50mm lower electrode sheet. -22 - 201107831 Further, a flexible transparent insulating film made of a polyethylene terephthalate (PET) film having a thickness of 0.125 mm was used, and an ITO film having a thickness of 20 nm was formed on one surface by sputtering. After cutting into a sheet having the same size as the lower electrode panel, the ITO film of the unnecessary portion is removed by etching, thereby forming a transparent electrode having a rectangular upper portion. Further, the silver paste is screen-printed, whereby an upper bus bar disposed on both sides facing the lateral direction of the upper transparent electrode and a pull wire for outputting from the upper bus bar to the outside are formed as the upper portion. The circuit was used to produce an upper electrode piece of 80 mm in length and 50 mm in width. Further, a flexible transparent insulating film made of a PET film having a thickness of 0.05 mm is used, and a colored ink having a pigment dispersed in a polyester resin on one side is screen-printed to form a transparent window having a vertical length of 65 mm and a width of 40 mm. The decorative layer is made, and a decorative piece of 80 mm in length and 50 mm in width is produced. Further, a flexible transparent insulating film made of a PET film having a thickness of 0.125 mm was used, and an ultraviolet-curable acrylic hard coat layer was applied by gravure printing on one side to obtain a hard coat sheet of 80 mm in length and 50 mm in width. . Next, a PSA made of a resin having a thickness of 0.025 mm (the same as described above) is applied over the entire surface of the upper electrode sheet opposite to the upper transparent electrode, and the decorative sheet side and the decorative layer side. On the opposite side, the surface of the decorative layer side of the decorative sheet is bonded to the surface of the hard coat sheet on the PET film side. Next, the screen is printed on the upper transparent electrode side of the upper electrode sheet. On the surface, a paste layer of a predetermined pattern having a thickness of 0.025 mm and a length of 80 mm and a width of 50 mm, which is made of an acrylic resin and colored in black, is formed, and the lower electrode sheets are bonded together by the paste layer -23 - 201107831 to separate the electrodes. The paste layer is composed of a frame portion and a plurality of islands having a diameter of 1 mm and a spacing of 2 mm, wherein the frame portion is formed by three sides along the outer circumference and the end of the FPC having a width of 20 mm. The one side of the portion is formed so as to avoid the transparent window portion and also spread over the circuit portion, and is distributed and disposed inside the frame portion. Further, on one side of the end portion of the FPC inserted into the front portion, there is an FPC insertion region having a width of only 22 mm from the outer circumference. Then, in a state where the lower electrode sheet provided with the conductive adhesive of the FPC is placed between the lower electrode sheet and the upper electrode sheet, the carrier is slidably moved to a predetermined position, and then the lower electrode sheet side of the heater is placed. Pressing, thereby performing thermocompression bonding of the FPC from the circuits 6c, 8c. Finally, by integrally coating the PSA composed of propylene having a thickness of 0.025 mm, the aforementioned face and the lower portion having the aforementioned protective panel body are bonded. a phase of the electrode sheet and the lower transparent electrode side [Example 2] except that the frame portion of the paste layer does not have an FPC insertion region, and is formed in a frame portion and a front electrode sheet of the paste layer through the corresponding terminal portion. The through hole of the protective panel main body was carried out in the same manner as in the first embodiment except that the back surface of the protective panel was connected to the FPC. The protective panel produced in the same manner as in Example 1 does not cause a malfunction even if a strong load is applied to the entire surface, or the appearance is not a pattern of a dog portion (a circle width of 3 mm, and the island is a frame-shaped 4 mm portion of the fifth frame). The insertion is placed on the reverse side of the resin-injecting portion of the front terminal portion. The lower part of the lower-X-ntfto -1⁄2 body is better in appearance. -24- 201107831 The present invention fully describes the related aspects while referring to the additional drawings.
