Description
本考案は、タッチパネルに関し、特に静電容量式タッチパネルに関する。 The present invention relates to a touch panel, and more particularly to a capacitive touch panel.
現在、使われている静電容量式タッチパネルの種類が多く、例えば、一番多く使われるGG(二層ガラス)構造、PG(PET/ガラス)構造、GFF(ガラス/FILM/FILM)構造、OGS(ワンガラス)構造などがある。 There are many types of capacitive touch panels currently in use, for example, the most commonly used GG (double-layer glass) structure, PG (PET / glass) structure, GFF (glass / FILM / FILM) structure, OGS (One glass) structure.
本出願人は、静電容量式タッチパネルの製造/使用する過程で以下の問題点を発見した。一番多く使われるGG構造の静電容量式タッチパネルは、二層ガラスを使い、且つ2つの硬性ガラスの接着率と接着効率が低いので、コストが高くつき、厚さが厚い。PG構造は、表面がPET膜からなり、表面の硬度が低いので、傷がつきやすく、且つ構造による制限が多い。GFF構造は、二層のITO膜を必要とし、二回の接着工程を実施しなればならないので、材料コストと製造コストが高くつき、良品率と効率が低く、且つ接着したフレキシブルプリント基板(FPC)にも機能的な問題がある。OGS構造は、製造する過程で黄光形成工程と電気接続工程を実施しなければならないので、製造効率が低く、コストが高い。 The present applicant has discovered the following problems in the process of manufacturing / using a capacitive touch panel. The most commonly used capacitive touch panel with a GG structure uses a double-layer glass, and the adhesion rate and adhesion efficiency of the two hard glasses are low, resulting in high costs and a large thickness. Since the surface of the PG structure is made of a PET film and the hardness of the surface is low, the PG structure is easily scratched and is often limited by the structure. The GFF structure requires a two-layer ITO film and requires two bonding steps, resulting in high material cost and manufacturing cost, low yield rate and low efficiency, and bonded flexible printed circuit board (FPC). ) Also has a functional problem. In the OGS structure, since the yellow light forming process and the electrical connection process must be performed in the manufacturing process, the manufacturing efficiency is low and the cost is high.
本考案の目的は、上述した技術問題を解決するために、構造が簡単で、製造コストが低く、製造効率が高い静電容量式タッチパネルを提供することにある。 An object of the present invention is to provide a capacitive touch panel that has a simple structure, a low manufacturing cost, and a high manufacturing efficiency in order to solve the technical problems described above.
