Description
本考案は、高光反射性の赤外線反射ストリップに関し、特に、光学式タッチパネル液晶表示装置に適用される赤外線反射ストリップ、及び該赤外線反射ストリップを含む液晶表示装置に関する。 The present invention relates to an infrared reflective strip having high light reflectivity, and more particularly to an infrared reflective strip applied to an optical touch panel liquid crystal display device and a liquid crystal display device including the infrared reflective strip.
液晶ディスプレイ（Ｌｉｑｕｉｄ Ｃｒｙｓｔａｌ Ｄｉｓｐｌａｙ；ＬＣＤ）は、体積が小さく、高画質、低消費電力、輻射がないなどの利点があるため、近年、情報又は映像を表示する必要がある種々の電子製品、例えば、テレビ受像機、パーソナルコンピュータ、ノートブック型コンピュータ、携帯電話、携帯情報端末（ＰＤＡ）などに広く適用されている。また、産業の発展に伴い、電子製品の使い勝手及び趣味性を向上するために、電子製品、特に消費性電子製品のヒューマン・マシン・インターフェースのコミュニケーションに対するニーズが年々高まっている。これにより、タッチパネル式液晶スクリーンの発展にも寄与している。 A liquid crystal display (LCD) has advantages such as a small volume, high image quality, low power consumption, and no radiation. Therefore, various electronic products that need to display information or video in recent years, for example, Widely applied to television receivers, personal computers, notebook computers, mobile phones, personal digital assistants (PDAs), and the like. In addition, with the development of the industry, in order to improve the usability and hobbies of electronic products, there is an increasing need for communication of human-machine interfaces of electronic products, particularly consumer electronic products, year by year. This contributes to the development of touch panel type liquid crystal screens.
一般的には、タッチパネル式液晶スクリーンは、タッチ方式によって、抵抗式と、容量式と、光学式とのタッチパネル液晶スクリーンに分けられている。そのうち、光学式タッチパネル液晶スクリーンは、精度が高く、且つ応答速度が速いという特徴があるため、主流となっているタッチパネル式液晶スクリーンの一つになってきている。
光学式タッチパネル液晶スクリーンは、光遮断原理によりスクリーン上のタッチパネル点を位置決めし、例えば、パネルの範囲内に光源と受光器を満遍なく設置しマトリクスを構成することにより、光が遮断された際、光を受光することができなかった受光器の位置を検知することができ、更に精度良くその位置を確定することができる。従来技術においては、パネルのＸ軸線及びＹ軸線上の隣接する両側に、複数の発光ダイオードを設置し、対向する側辺へ赤外線を射出し、そして、対向する両側辺上には、複数の赤外線センサを設置し、発光ダイオードから射出された赤外線を受信している。これにより、液晶スクリーン全面に高密度の位置決め点からなるグリッドを構成し、位置決めを精度良く行う効果が得られる。しかしながら、このようなパネルの範囲内に光源と受光器を満遍なく設置する構成には、下記のような欠点がある。即ち、これらのＬＥＤ光源は、大量の電力を消費するだけでなく、電子装置において大量の熱エネルギーを生成する恐れもある。現在では薄型化や軽量化が求められている電子製品産業には、限られた空間に各部品をよりコンパクトに実装することが必要となってきている。これに起因して、熱エネルギーの発散は重要な問題となりつつある。
Generally, the touch panel type liquid crystal screen is divided into a resistance type, a capacitance type, and an optical type touch panel liquid crystal screen according to a touch method. Among them, the optical touch panel liquid crystal screen is one of the mainstream touch panel liquid crystal screens because of its high accuracy and high response speed.
An optical touch panel LCD screen positions the touch panel point on the screen according to the light blocking principle.For example, when the light is blocked by arranging light sources and light receivers uniformly within the range of the panel to form a matrix, It is possible to detect the position of the light receiver that could not receive light, and to determine the position with higher accuracy. In the prior art, a plurality of light emitting diodes are installed on both sides adjacent to each other on the X axis and Y axis of the panel, infrared rays are emitted to opposite sides, and a plurality of infrared rays are emitted on opposite sides. A sensor is installed to receive infrared light emitted from the light emitting diode. Thereby, the grid which consists of a high-density positioning point is comprised in the whole liquid-crystal screen, and the effect which performs positioning accurately is acquired. However, the configuration in which the light source and the light receiver are uniformly installed within the range of such a panel has the following drawbacks. That is, these LED light sources not only consume a large amount of power, but can also generate a large amount of thermal energy in the electronic device. Currently, in the electronic product industry that is required to be thinner and lighter, it is necessary to mount each component more compactly in a limited space. Due to this, the divergence of thermal energy is becoming an important issue.
前記のような光学式タッチパネル液晶スクリーンの構成以外にも、他の構成が存在している。この構成においては、パネルの範囲内に光源と受光器を満遍なく設置する構成を採用するのではなく、液晶スクリーンの左上及び右上にＣＭＯＳレンズをセンサとしてそれぞれ設置し、その近傍に赤外線を出射する装置（例えば、ＬＥＤ）を設置し、更に液晶スクリーンの外框側に赤外線を反射するための赤外線反射ストリップを設置することにより、液晶スクリーン上に満遍なく赤外線が行き渡るようにする。そして、指やその他の物体（例えば、タッチペン）がスクリーンにタッチしたとき、光が遮断されたことにより、センサにより障害物の存在を検知することができ、更に三角関数による演算により、タッチされた位置を求めることができ、位置決めを精度良く行う効果が得られる。このような光学式タッチパネル液晶スクリーンの構成においては、赤外線反射ストリップの反射効果が向上するほど、液晶スクリーンにおいてのＬＥＤ光源の消費電力がより削減されることとなり、それに伴って、発生した熱エネルギーも減少する。しかし、既存の赤外線反射ストリップの光反射効果はまだ十分とはいえず、向上させる余地がある。 In addition to the configuration of the optical touch panel liquid crystal screen as described above, there are other configurations. In this configuration, instead of adopting a configuration in which light sources and light receivers are uniformly installed within the range of the panel, a CMOS lens is installed as a sensor in the upper left and upper right of the liquid crystal screen, and infrared rays are emitted in the vicinity thereof. (For example, LEDs) are installed, and an infrared reflecting strip for reflecting infrared rays is further provided on the outer side of the liquid crystal screen so that the infrared rays are evenly distributed on the liquid crystal screen. When a finger or other object (for example, a touch pen) touches the screen, the presence of an obstacle can be detected by the sensor because the light is blocked, and the touch is further performed by calculation using a trigonometric function. The position can be obtained, and the effect of accurately positioning can be obtained. In such a configuration of the optical touch panel liquid crystal screen, the power consumption of the LED light source in the liquid crystal screen is further reduced as the reflection effect of the infrared reflective strip is improved, and the generated thermal energy is also reduced accordingly. Decrease. However, the light reflection effect of the existing infrared reflective strip is not yet sufficient, and there is room for improvement.
従来の光学式タッチパネル液晶スクリーンには、上述した問題点が存在しているので、赤外線反射ストリップの光反射効率を向上させることができ、そして光学式タッチパネル液晶スクリーンの消費電力及び熱エネルギーを減少することができる赤外線反射ストリップ及び該赤外線反射ストリップを含む液晶表示装置の提供が望まれているのが現状である。 Since the conventional optical touch panel liquid crystal screen has the above-mentioned problems, the light reflection efficiency of the infrared reflective strip can be improved, and the power consumption and thermal energy of the optical touch panel liquid crystal screen can be reduced. It is currently desired to provide an infrared reflective strip that can be used and a liquid crystal display device including the infrared reflective strip.
本考案は、従来における前記諸問題を解決し、以下の目的を達成することを課題とする。即ち、本考案は、光反射効率を向上させることができ、光学式タッチパネル液晶スクリーンに適用される赤外線反射ストリップ及び該赤外線反射ストリップを含む液晶表示装置を提供することを目的とする。 An object of the present invention is to solve the conventional problems and achieve the following objects.

以下、本考案の実施形態について図面に基づいて説明する。なお、これによって本考案が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.
（第１実施例）
図１Ａ及び図１Ｂに示す本考案の第１実施例を参照し、本考案の液晶表示装置に用いられる赤外線反射ストリップ１０を説明する。
図１Ａ及び図１Ｂに示すように、本考案の赤外線反射ストリップ１０は、剥離紙７０及び該剥離紙７０上に塗布される粘着層６０を含む、ハロゲンを含まないベース材と、前記粘着層６０に積層され、かつ複数の光反射構成（reflecting configurations）２２が形成される構成面と底面とを有する光反射基材２０と、を主に有している。この第１実施例では、これらの光反射構成２２はビーズ状の光反射構成であり、また、光反射効果を向上させるために、これらの光反射構成の半球形面上には、金属薄膜（例えば、アルミニウム金属薄膜）が電気メッキされている。好ましくは、１層の第２保護層５０が、前記光反射基材２０の底面と前記粘着層６０との間に設置されている。
(First embodiment)
An infrared reflecting strip 10 used in a liquid crystal display device of the present invention will be described with reference to a first embodiment of the present invention shown in FIGS. 1A and 1B.
As shown in FIG. 1A and FIG. 1B, the infrared reflective strip 10 of the present invention includes a release paper 70 and a base material that does not contain halogen, including a release paper 70 and an adhesive layer 60 applied on the release paper 70. And a light reflecting substrate 20 having a configuration surface and a bottom surface on which a plurality of light reflecting configurations 22 are formed. In this first embodiment, these light reflecting structures 22 are bead-shaped light reflecting structures, and in order to improve the light reflecting effect, a metal thin film (on the hemispherical surface of these light reflecting structures is used. For example, an aluminum metal thin film) is electroplated. Preferably, one second protective layer 50 is disposed between the bottom surface of the light reflecting substrate 20 and the adhesive layer 60.
また、第１実施例に係る赤外線反射ストリップ１０は、前記光反射基材２０の構成面上に覆われる透明な第１保護層３０を更に含む。前記透明な第１保護層３０は、高透過率及び低反射率を有する材料、例えば熱可塑性ポリウレタン（ＴＰＵ）材料からなることが好ましい。これにより、赤外線が反射されていない場合、前記第１保護層３０を通して前記光反射基材２０の構成表面に達し、そして、表面上に金属薄膜が電気メッキされている光反射構成２２によって反射された後、前記第１保護層３０を通して、赤外線を十分に反射することによって、赤外線光反射効果を最大限に提供することができる。また、前記第１保護層３０が空気中の湿気を吸収してその光学特性を損なうことを防止するために、耐ＵＶ材料層４０は前記第１保護層３０の表面上に塗布されていることが好ましい。
この第１実施例に係る赤外線反射ストリップ１０の耐ＵＶ材料層４０が揃って積層された後、高周波又は超音波処理の方式により、これらの材料層が粘着されて適切なサイズに切断されることにより、必要となる赤外線反射ストリップ１０が得られる。
In addition, the infrared reflective strip 10 according to the first embodiment further includes a transparent first protective layer 30 covered on the constituent surface of the light reflecting substrate 20. The transparent first protective layer 30 is preferably made of a material having a high transmittance and a low reflectance, for example, a thermoplastic polyurethane (TPU) material. Thereby, when infrared rays are not reflected, it reaches the constituent surface of the light-reflecting substrate 20 through the first protective layer 30 and is reflected by the light-reflecting constitution 22 having a metal thin film electroplated on the surface. After that, by sufficiently reflecting infrared rays through the first protective layer 30, the infrared light reflection effect can be provided to the maximum. Further, the UV-resistant material layer 40 is applied on the surface of the first protective layer 30 in order to prevent the first protective layer 30 from absorbing moisture in the air and damaging its optical characteristics. Is preferred.
After the UV-resistant material layer 40 of the infrared reflective strip 10 according to the first embodiment is aligned and laminated, these material layers are adhered and cut into an appropriate size by a high frequency or ultrasonic treatment method. Thus, the necessary infrared reflecting strip 10 is obtained.
（第２実施例）
図２Ａ及び２Ｂは、本考案による第２実施例の赤外線反射ストリップ１０’を示す。第２実施例の構成と第１実施例に係る赤外線反射ストリップ１０とは略同一であり、両者の相違点は、単に、第２実施例の光反射構成２２’がビーズ状構成ではなく、角錐状構成であることだけである。第２実施例の光反射構成２２’は角錐形状であるが、得られる赤外線光反射効果は、第１実施例と実質的に同一である。
(Second embodiment)
2A and 2B show a second embodiment of an infrared reflective strip 10 'according to the present invention. The configuration of the second embodiment and the infrared reflecting strip 10 according to the first embodiment are substantially the same, and the difference between the two is simply that the light reflecting configuration 22 'of the second embodiment is not a bead-shaped configuration but a pyramid. It is only a shape configuration. The light reflecting structure 22 'of the second embodiment has a pyramid shape, but the obtained infrared light reflecting effect is substantially the same as that of the first embodiment.
次に、図３を参照し、本考案に係るもう一つの態様の上述した赤外線反射ストリップを含む液晶表示装置１００について説明する。
図３に示すように、前記液晶表示装置１００は、液晶パネル１２０と、光学タッチユニットと、を含み、前記光学タッチユニットは、前記液晶パネル１２０の１つの側辺に設置される複数の赤外線光源１３０と、前記液晶パネル１２０の左上隅及び右上隅にそれぞれ設置される、例えば、ＣＭＯＳ光学レンズの２つの赤外線感知素子１４０と、前記液晶パネル１２０の赤外線光源が設けられていないその他の３つの側辺上に設置され、赤外線光源１３０から射出した光を液晶パネル１２０全体に反射して光学タッチに必要な光とするための３本の本考案の赤外線反射ストリップ１０と、を含む。
Next, a liquid crystal display device 100 including the above-described infrared reflecting strip according to another aspect of the present invention will be described with reference to FIG.
As shown in FIG. 3, the liquid crystal display device 100 includes a liquid crystal panel 120 and an optical touch unit, and the optical touch unit includes a plurality of infrared light sources installed on one side of the liquid crystal panel 120. 130, two infrared sensing elements 140 of, for example, a CMOS optical lens, and the other three sides of the liquid crystal panel 120 where the infrared light source is not provided. And three infrared reflecting strips 10 of the present invention for reflecting light emitted from the infrared light source 130 to the entire liquid crystal panel 120 and making it necessary for optical touch.
従来の光学タッチパネル液晶表示装置には、タッチの検知感度及びタッチ点の密度を向上させるために、多くの光源（例えば、ＬＥＤランプ）及び受光器により液晶スクリーン上に高密度の光学グリッドを構成するのが一般であるが、光源及び受光器の作動には電力を消費する必要があるため、液晶表示装置において使用される光源及び受光器が多ければ、消費電力が大きくなり、熱エネルギーも多く発生し、熱エネルギーの発散の問題もより大きくなる。それに対して、本考案の高性能赤外線反射ストリップは、反射光を利用して光学タッチに必要な光を提供しているので、赤外線反射ストリップ自身では、電力を消費して発光する必要がなく、しかも熱エネルギーを発生することもない。そのため、本考案の高性能赤外線反射ストリップを光学タッチの光源とする液晶ディスプレイは、従来の液晶表示装置よりも少ない光源により液晶パネルの表面全面に光学タッチに必要な光を提供することができる。 In a conventional optical touch panel liquid crystal display device, a high-density optical grid is formed on a liquid crystal screen by a large number of light sources (for example, LED lamps) and light receivers in order to improve touch detection sensitivity and touch point density. However, since it is necessary to consume power to operate the light source and the light receiver, the more the light source and light receiver used in the liquid crystal display device, the larger the power consumption and the more heat energy is generated. However, the problem of heat energy divergence also becomes larger. On the other hand, the high-performance infrared reflective strip of the present invention uses reflected light to provide light necessary for optical touch, so the infrared reflective strip itself does not need to consume power and emit light. Moreover, no thermal energy is generated. Therefore, the liquid crystal display using the high-performance infrared reflective strip of the present invention as a light source for optical touch can provide light necessary for optical touch on the entire surface of the liquid crystal panel with fewer light sources than a conventional liquid crystal display device.
したがって、本考案の赤外線反射ストリップが適用される液晶表示装置は、電力の消費を大幅に削減し、熱エネルギーの発生を減少させることができ、これにより、従来の液晶表示装置においての高いエネルギー消費、高い熱生成、及び放熱などの問題を有効に解決することができる。本考案の赤外線反射ストリップ、及び該赤外線反射ストリップを含む液晶表示装置は、上述した、従来の赤外線反射ストリップ及び液晶表示装置よりも優れている利点を有しているため、本考案の赤外線反射ストリップ及び液晶表示装置は極めて産業上利用可能性が高い。 Therefore, the liquid crystal display device to which the infrared reflective strip of the present invention is applied can significantly reduce power consumption and reduce the generation of thermal energy, thereby increasing the energy consumption in the conventional liquid crystal display device. Thus, problems such as high heat generation and heat dissipation can be effectively solved. The infrared reflective strip of the present invention and the liquid crystal display device including the infrared reflective strip have the advantages over the above-described conventional infrared reflective strip and liquid crystal display device. In addition, the liquid crystal display device is extremely highly industrially applicable.
