Description

本発明は、液晶ディスプレイ等の表示画面の表面に配置されて、データ入力を行うためのタッチパネルに関するものである。   The present invention relates to a touch panel arranged on the surface of a display screen such as a liquid crystal display for inputting data.

従来、カーナビゲーション、自動販売機あるいは各種の端末機等において、液晶ディスプレイ等の表示画面の表面に配置されて、透視した画像の指示等に基づいて操作者が表示画面を指あるいはペンで押すことでデータ入力を行うタッチパネルが知られている。この種のタッチパネルは、例えば、図２に示すように、上部透明基板２の下面に矩形状に形成された上部透明電極層３を形成し、下部透明基板４の上面に矩形状に形成された下部透明電極層５を形成するとともにその下部透明電極層５の上面にドットスペーサ６を一定の厚さで形成し、上部透明基板２及び下部透明基板４の周縁部に一定の間隔を形成するシール部材７を設け、ドットスペーサ６を介してそれぞれの上部透明電極層３及び下部透明電極層５を一定の間隔で対峙させた構造を有するものである。なお、図示していないが、上部透明電極層３には、両端部に一対の上部電極、下部透明電極層５には、上部電極と直交する方向の両端部に一対の下部電極が形成されている。   Conventionally, in a car navigation system, a vending machine, or various terminals, an operator presses the display screen with a finger or a pen on the surface of a display screen such as a liquid crystal display based on instructions of a fluoroscopic image. A touch panel for inputting data is known. For example, as shown in FIG. 2, this type of touch panel has an upper transparent electrode layer 3 formed in a rectangular shape on the lower surface of the upper transparent substrate 2, and is formed in a rectangular shape on the upper surface of the lower transparent substrate 4. A seal that forms the lower transparent electrode layer 5, forms dot spacers 6 with a certain thickness on the upper surface of the lower transparent electrode layer 5, and forms a certain interval between the peripheral edges of the upper transparent substrate 2 and the lower transparent substrate 4. A member 7 is provided, and each of the upper transparent electrode layer 3 and the lower transparent electrode layer 5 is opposed to each other at a constant interval via a dot spacer 6. Although not shown, the upper transparent electrode layer 3 has a pair of upper electrodes at both ends, and the lower transparent electrode layer 5 has a pair of lower electrodes at both ends in a direction perpendicular to the upper electrode. Yes.

このような構成を有するタッチパネル１は、液晶ディスプレイの表示画面の表面に配置され、上部電極及び下部電極が液晶ディスプレイの電子機器に接続されている。このタッチパネル１では、表示画面の表示を見ながら、上部透明基板２の表面を指あるいはペン等で押圧力を加えると、上部透明基板２が撓むことで、上部透明電極層３が下部透明電極層５に接触し、電子機器により押圧された箇所が検出され、データ入力により種々の機能が動作するようになっている。   The touch panel 1 having such a configuration is disposed on the surface of a display screen of a liquid crystal display, and an upper electrode and a lower electrode are connected to an electronic device of the liquid crystal display. In this touch panel 1, when a pressing force is applied to the surface of the upper transparent substrate 2 with a finger or a pen while observing the display on the display screen, the upper transparent substrate 2 bends so that the upper transparent electrode layer 3 becomes the lower transparent electrode. A portion touching the layer 5 and pressed by the electronic device is detected, and various functions are operated by data input.

従来のタッチパネル１において、上部透明基板２及び下部透明基板４は、例えば、種々厚さを有するガラス材あるいはプラスチック等が使用されている。例えば、上部透明基板２及び下部透明基板４が両方ともガラス材やプラスチック材で形成されたもの、上部透明基板２がプラスチック材で形成され下部透明基板４がガラス材が使用されたもの等が知られている。   In the conventional touch panel 1, for example, glass materials or plastics having various thicknesses are used for the upper transparent substrate 2 and the lower transparent substrate 4. For example, it is known that both the upper transparent substrate 2 and the lower transparent substrate 4 are made of glass material or plastic material, the upper transparent substrate 2 is made of plastic material, and the lower transparent substrate 4 is made of glass material. It has been.

例えば、上部透明基板２及び下部透明基板４が両方ともガラス材で形成されたタッチパネルが特許文献１に記載され、また両方ともプラスチック材で形成されたタッチパネルが特許文献２に記載され、上部透明基板２がプラスチック材で形成され下部透明基板４がガラス材で形成されたタッチパネルが特許文献３に記載されている。   For example, Patent Document 1 discloses a touch panel in which both the upper transparent substrate 2 and the lower transparent substrate 4 are formed of a glass material, and Patent Document 2 describes a touch panel in which both of the upper transparent substrate 2 and the lower transparent substrate 4 are formed of a plastic material. Patent Document 3 discloses a touch panel in which 2 is formed of a plastic material and the lower transparent substrate 4 is formed of a glass material.

Therefore, for example, it may not be suitable for character input with a pen, and a touch panel used in mobile communication devices such as a mobile phone in recent years may be difficult to operate in terms of pressing pressure. In addition, a touch panel in which the upper transparent substrate 2 is formed of a plastic material can be operated with a small pressing pressure, but there is a possibility that the durability is not satisfactory or operational reliability is problematic.
