Description
本発明は、携帯電話、デジタルカメラ、テレビ、コンピュータ、その他の電子機器のパネル基板に加飾を施してなる画像表示パネルに関する。 The present invention is a mobile phone, digital camera, relates TV, computers and other electronic devices of the image display panel comprising applying decorative panel substrate.
従来の電子機器等の画像表示パネルに設けられたパネル基板に加飾を施し、その上に光学両面テープを貼り付けた場合、加飾によって生じた段差の内側に空気層が発生することがある。即ち、図６（ａ）に示すように、画像表示をなす透視可能なパネル基板２１の背面２１ａに加飾を施し、この加飾をなす層（以下、「加飾層」と云う）２２の上面２２ａ及びパネル基板２１の背面２１ａに光学両面テープ２３を貼り付けた場合、図６(ｂ)に示すように、パネル基板２１と加飾層２２との段差２４の隅部等に空気溜まりのような空気層２５が生じる。 When decoration is applied to a panel substrate provided on an image display panel of a conventional electronic device or the like, and an optical double-sided tape is attached thereon, an air layer may be generated inside the step formed by the decoration. . That is, as shown in FIG. 6A, decoration is applied to the rear surface 21a of the see-through panel substrate 21 that displays an image, and a layer 22 (hereinafter referred to as a “decoration layer”) that performs the decoration is provided. When the optical double-sided tape 23 is affixed to the upper surface 22a and the back surface 21a of the panel substrate 21, as shown in FIG. 6 (b), air pockets are formed at the corners of the step 24 between the panel substrate 21 and the decorative layer 22. Such an air layer 25 is generated.
そこで、上記のようにパネル基板２１と加飾層２２との段差２４に生じた空気層２５を除去するために、次工程で、加圧脱泡装置を用いて空気層２２の空気を抜く作業を行うことも可能であるが、加圧脱泡後、光学両面テープ２３の復元性によって経時的に空気層２５が再発するおそれがある。さらには、光学両面テープ２３を平滑に貼り付けるのが困難であるという問題点もある。 Therefore, in order to remove the air layer 25 generated in the step 24 between the panel substrate 21 and the decorative layer 22 as described above, in the next step, the operation of extracting air from the air layer 22 using a pressure defoaming device. However, the air layer 25 may recur over time due to the restoring property of the optical double-sided tape 23 after defoaming under pressure. Furthermore, there is a problem that it is difficult to apply the optical double-sided tape 23 smoothly.
また、図６（ａ）に示すように、加飾層２２を例えば２層のインキ層２２ｃ、２２ｄで重ね合わせた構成とすることによって加飾層２２に段差２２ｂを設けると、段差２４の幅が大きくなる。この状況でパネル基板２１と加飾層２２の背面に光学両面テープ２３を貼り合せた場合、図６（ｂ）に示すように、光学両面テープ２３が平滑にならずに段差２４の近傍に折れ目２９のような変形が生じる。そして、この光学両面テープ２３の背面に他の部材２７を貼り付けると、部材２７は硬質であって変形せず、ＰＥＴ樹脂等によるパネル基板２１が部材２７側へ強制的に引っ張られて変形した状態で付着し、パネル基板２１の内部が背面側へ湾曲形状３１に変形する。また、このとき、図７に示すように、画像表示パネル２０を前方から見たとき、上記の段差２４の内側に沿って生じた光学両面テープ２３の折れ目２９が、加飾層２２の内側近傍に沿って筋状に見えるという問題があった。 Further, as shown in FIG. 6A, when the step 22b is provided in the decorative layer 22 by superimposing the decorative layer 22 with, for example, two ink layers 22c and 22d, the width of the step 24 is obtained. Becomes larger. In this situation, when the optical double-sided tape 23 is bonded to the back surface of the panel substrate 21 and the decorative layer 22, the optical double-sided tape 23 does not become smooth but folds in the vicinity of the step 24 as shown in FIG. Deformation like the eye 29 occurs. Then, when another member 27 is attached to the back surface of the optical double-sided tape 23, the member 27 is hard and does not deform, and the panel substrate 21 made of PET resin or the like is forcibly pulled toward the member 27 and deformed. It adheres in a state, and the inside of the panel substrate 21 is deformed into a curved shape 31 toward the back side. At this time, as shown in FIG. 7, when the image display panel 20 is viewed from the front, the fold 29 of the optical double-sided tape 23 generated along the inner side of the step 24 is the inner side of the decorative layer 22. There was a problem of appearing streaks along the vicinity.
さらに、図６（ａ）に示すように加飾層２２に抜き穴２６等が形成されている場合、図６（ｂ）に示すようにパネル基板２１と加飾層２２の背面に光学両面テープ２３を貼り合せ、図６(ｃ)に示すように光学両面テープ２３の背面に他の部材２７を押圧状態で貼り付けると、図６（ｄ）に示すようにパネル基板２１が部材２７側へ強制的に引っ張られた状態で付着する。このため、抜き穴２６の箇所におけるパネル基板２１が背面側へ凹状に歪んだ形状となる。 Further, when a punch hole 26 or the like is formed in the decorative layer 22 as shown in FIG. 6A, an optical double-sided tape is attached to the back surface of the panel substrate 21 and the decorative layer 22 as shown in FIG. 6B. 23, and another member 27 is stuck on the back surface of the optical double-sided tape 23 as shown in FIG. 6C, the panel substrate 21 moves toward the member 27 as shown in FIG. 6D. It adheres in a state where it is forcibly pulled. For this reason, the panel board | substrate 21 in the location of the punch hole 26 becomes a shape distorted concavely toward the back side.
さらにまた、図７に示すようにパネル基板２１の背面にロゴマーク等の加飾部２８を施した場合、その断面形状は、図８（ａ）に示すようになる。この図は、パネル基板２１と加飾部２８の背面に光学両面テープ２３を貼り付けたものであり、光学両面テープ２３は加飾部２８の厚さに沿って波状に形成されたものとなる。そして、図８(ｂ)、（ｃ）に示すように、光学両面テープ２３の背面にガラス板等の他の硬質の部材２７を張り合わせた場合、各加飾部２８、２８間の光学両面テープ２３が部材２７側へ引っ張られて変形し、ＰＥＴ樹脂等からなるパネル基板２１が加飾部２８ごとに前面側へ凸状の変形２１ｂを生じる。なお、この凸条の変形２１ｂは、図７に示すように、加飾部２８ごとに例えば輪形の歪み３０となって粗悪な変形を生じることとなる。 Furthermore, as shown in FIG. 7, when the decoration part 28, such as a logo mark, is given to the back surface of the panel board | substrate 21, the cross-sectional shape will become as shown to Fig.8 (a). In this figure, an optical double-sided tape 23 is attached to the back surface of the panel substrate 21 and the decorative portion 28, and the optical double-sided tape 23 is formed in a wave shape along the thickness of the decorative portion 28. . Then, as shown in FIGS. 8B and 8C, when another hard member 27 such as a glass plate is attached to the back surface of the optical double-sided tape 23, the optical double-sided tape between the decorative portions 28 and 28 is provided. 23 is pulled to the member 27 side and deformed, and the panel substrate 21 made of PET resin or the like produces a convex deformation 21b on the front side for each decorating portion 28. In addition, as shown in FIG. 7, the convex deformation 21 b becomes, for example, a ring-shaped distortion 30 for each decoration portion 28, resulting in a rough deformation.

即ち、特許文献１の画像表示装置及びその製造方法においては、各スペーサの上面には硬化樹脂が施されず、また余剰の硬化樹脂はスペーサとスペーサとの間の切欠き部から排出させるようにしているため、透明パネルの周部に設けたスペーサを連続的に形成することができず、切欠き部毎に途切れた形状となる。 That is, in the image display device and the manufacturing method thereof in Patent Document 1, the upper surface of each spacer is not subjected to cured resin, and excess cured resin is discharged from a notch between the spacers. For this reason, the spacers provided on the peripheral portion of the transparent panel cannot be formed continuously, resulting in a cut shape at each notch.
本発明は、特許文献１とは異なり、パネル基板の背面に連続的な加飾層を施すことが可能であり、この加飾層の上面に光学両面テープを貼り付けた場合に、加飾層の段差によって空気層が生じるのを解消すると共に、パネル基板に変形が生じることなく平滑に保つことができるようにしたものである。 Unlike patent document 1, this invention can give a continuous decoration layer on the back surface of a panel substrate, and when an optical double-sided tape is affixed on the upper surface of this decoration layer, a decoration layer This eliminates the formation of an air layer due to the step, and allows the panel substrate to be kept smooth without deformation.
即ち、本発明は、電子機器等に設けられた画像表示部のパネル基板に加飾層を施し、その加飾層の上に光学両面テープを貼り付ける際、気泡や空気層が生じることがないように、パネル基板の背面部を平滑にすることによりパネル基板を歪みの無い平滑状に形成することができる画像表示パネルを提供することを目的とする。 That is, according to the present invention, when a decorative layer is applied to a panel substrate of an image display unit provided in an electronic device or the like, and an optical double-sided tape is applied on the decorative layer, no bubbles or air layers are generated. as such, an object of the invention to provide an image display panel which is capable of forming a panel substrate distortion free smooth shape by smoothing the back of the panel substrate.

In addition to filling, the back surface of the cured resin 4 is cured in a smooth state.
図１に示すものは、上記の構成を有する画像表示パネル１の実施例であり、携帯電話の表示パネルとして使用するものである。ただし、この図１に示すものは、本発明の一実施例であり、本発明は、その他の電子機器、即ち携帯電話、デジタルカメラ、テレビ、コンピュータ等の電子機器に応じた画像表示パネル１として構成可能である。 FIG. 1 shows an embodiment of the image display panel 1 having the above-described configuration, which is used as a display panel for a mobile phone. However, what is shown in FIG. 1 is one embodiment of the present invention, and the present invention is an image display panel 1 according to other electronic devices, that is, electronic devices such as a mobile phone, a digital camera, a television, and a computer. It is configurable.
なお、図１は、本発明による個品の画像表示パネル１の実施例であり、その全体形状や加飾層３の形状等は適用する電子機器に応じて決定される。また、図２に示すものは、図１の画像表示パネル１を１枚のシートに複数枚形成して、画像表示パネル１の多面数を形成してなる大判５の一例を示すものである。 FIG. 1 is an example of an individual image display panel 1 according to the present invention, and the overall shape, the shape of the decorative layer 3 and the like are determined according to the applied electronic apparatus. FIG. 2 shows an example of a large format 5 in which a plurality of image display panels 1 of FIG. 1 are formed on a single sheet to form a multi-sided image display panel 1.
また、いずれの電子機器に適用する画像表示パネル１であっても、図３（ａ）又は図４（ａ）に示すように、透明をなすＰＥＴフィルム等によるパネル基板２の背面に、シルク印刷等によって加飾層３が施されている。 Moreover, even if it is the image display panel 1 applied to any electronic device, as shown in FIG. 3 (a) or FIG. 4 (a), silk printing is carried out on the back surface of the panel board | substrate 2 by transparent PET film etc. The decoration layer 3 is given by etc.
このような構成において、パネル基板２の素材としては、上記のようにＰＥＴフィルムを使用するほか、ポリカーボネート、アクリル、ガラス又はこれ等の部材の積層フィルム等が適用可能である。また、パネル基板２に設けた加飾層３は、パネル基板の周部に設ける加飾のほかに、このパネル基板２に地色をつけたり、ロゴやマーク等を施したりする場合にも施されるものである。 In such a configuration, as a material for the panel substrate 2, in addition to using a PET film as described above, polycarbonate, acrylic, glass, or a laminated film of these members can be applied. Further, the decorative layer 3 provided on the panel substrate 2 is applied to the case where a ground color is applied to the panel substrate 2 or a logo or a mark is applied in addition to the decoration provided on the peripheral portion of the panel substrate. Is.
なお、図４（ａ）に示すように、加飾層３は例えば２層のインキ層３ｄ、３ｅで重ね合わせた構成とすることができる。この場合、加飾層３の背面側の層３ｄを外方へ引き込ませた内周形状とすることによって段差３ｃを設け、パネル基板２の前方から加飾層３の背面側の層３ｄの内端が内方へ露呈したり、パネル基板２の前面側から見えたりすることがないようにしている。 In addition, as shown to Fig.4 (a), the decoration layer 3 can be set as the structure piled up by the two ink layers 3d and 3e, for example. In this case, a step 3c is provided by forming the inner surface of the decorative layer 3 on the back side so that the layer 3d on the back side is drawn outward, and the inside of the layer 3d on the back side of the decorative layer 3 from the front of the panel substrate 2 The end is not exposed inward or visible from the front side of the panel substrate 2.
また、本実施例においては、図４(ｂ)に示すように、パネル基板２の背面における加飾層３の段差３ｂの内側及び加飾層３の上面３ａに、硬化樹脂４を充填している。このとき、上記の加飾層３の段差３ｃにも気泡等が生じることなく硬化樹脂４が充填される。この硬化樹脂４の充填方法について詳細は後述するが、シルク印刷を用いて全面ベタ印刷によって充填する（図４（ｂ）参照）。また、他の実施例として、ディスペンサーを用いて充填する液量を制御するようにしてもよい（図５（ｂ）参照）。 Further, in this embodiment, as shown in FIG. 4B, the cured resin 4 is filled inside the step 3 b of the decorative layer 3 and the upper surface 3 a of the decorative layer 3 on the back surface of the panel substrate 2. Yes. At this time, the step 3c of the decorative layer 3 is filled with the cured resin 4 without generating bubbles or the like. Although the details of the filling method of the cured resin 4 will be described later, the filling is performed by solid printing using silk printing (see FIG. 4B). As another example, the amount of liquid to be filled may be controlled using a dispenser (see FIG. 5B).
いずれの充填方法であっても、充填後の硬化樹脂４の背面４ａに対して、フッ素やシリコン等による離型剤７を塗布したＰＥＴフィルム等のセパレータフィルム６で被覆し、加圧状態でＵＶ照射することによってＵＶ硬化させる。なお、硬化樹脂４をＰＥＴフィルム等のセパレータフィルム６で被覆した場合、ＵＶ照射の際に空気中の酸素の阻害を受けることなく良好な照射条件で照射することが可能となり、これによってパネル基板２の背面２ａや加飾層３に対する硬化樹脂４の粘着力が強くすることが可能となる。 In any filling method, the back surface 4a of the cured resin 4 after filling is covered with a separator film 6 such as a PET film coated with a release agent 7 such as fluorine or silicon, and UV is applied in a pressurized state. UV cure by irradiation. In addition, when the cured resin 4 is covered with a separator film 6 such as a PET film, it is possible to irradiate under favorable irradiation conditions without being obstructed by oxygen in the air during UV irradiation. The adhesive force of the cured resin 4 to the back surface 2a and the decorative layer 3 can be increased.
また、図３(ｄ)又は図４(ｅ)に示すように、セパレータフィルム６を剥離することによって、硬化樹脂４の背面４ａが平滑面を成す画像表示パネル１が形成される。なお、硬化樹脂４の背面とセパレータフィルム６との間に離型剤７を設けたのは、上記の硬化樹脂４の硬化後にセパレータフィルム６を剥離し易くするためのものである。また、セパレータフィルム６を剥離することによって、より薄厚の画像表示パネル１を得ることが可能となる。 Further, as shown in FIG. 3D or FIG. 4E, by separating the separator film 6, the image display panel 1 in which the back surface 4a of the cured resin 4 forms a smooth surface is formed. The reason why the release agent 7 is provided between the back surface of the cured resin 4 and the separator film 6 is to facilitate separation of the separator film 6 after the curing resin 4 is cured. Further, by peeling the separator film 6, it is possible to obtain a thinner image display panel 1.
さらに、図４(ｆ)に示すように、パネル基板２の背面２ａに施した硬化樹脂４の硬化後の平滑な背面４ａに光学両面テープ８を貼着すると、この光学両面テープ８の背面８ａの有する粘着力で画像表示パネル１の取付箇所や他の部品に接着することが可能となる。また、このように硬化した硬化樹脂４の平滑な背面に光学両面テープ８を貼り合わせた際、この光学両面テープ８もまた平滑状に貼り付けられるため、光学両面テープ８の他面をガラス板や他の部材等に貼り付けた際にもパネル基板２に変形が発生せず、パネル基板２を綺麗な平滑状に維持することができる。 Further, as shown in FIG. 4 (f), when the optical double-sided tape 8 is attached to the smooth back surface 4 a after curing of the cured resin 4 applied to the back surface 2 a of the panel substrate 2, the back surface 8 a of the optical double-sided tape 8. It becomes possible to adhere to the mounting location of the image display panel 1 and other parts by the adhesive strength of the. Further, when the optical double-sided tape 8 is bonded to the smooth back surface of the cured resin 4 thus cured, the optical double-sided tape 8 is also applied in a smooth shape. In addition, the panel substrate 2 is not deformed even when attached to other members or the like, and the panel substrate 2 can be maintained in a clean and smooth state.
以下、本発明による画像表示パネルの製造方法の一実施例について説明する。この実施例は、パネル基板２に施した加飾層３による段差３ｂを硬化樹脂４で充填する際、硬化樹脂４を全面ベタ印刷で充填する方法に関するものである。この実施例の図面としては、図３（ａ）〜(ｅ)及び図４（ａ）〜(ｆ)が相当する。なお、図３（ａ）〜(ｅ)は１枚のシートで複数の画像表示パネル１を製造可能とした大判５の平面図であり、図４（ａ）〜(ｆ)は個品の画像表示パネル１の断面を示すものである。 Hereinafter, an embodiment of a method for manufacturing an image display panel according to the present invention will be described.
