Description

Touch panel

一種觸控面板，尤指一種可減少導線之數量以及避免機構上之干涉與訊號受屏蔽的觸控面板。

A touch panel, especially a touch panel capable of reducing the number of wires and avoiding interference between the mechanism and the signal being shielded.

隨著近年來觸控面板技術之發展，現今具有顯示功能的可攜式電子裝置，如智慧型手機、平板電腦等皆改採用觸控面板來取代傳統佔據空間的機械式按鍵。
綜觀現有觸控面板中，較常被使用於可攜式電子裝置的多為電容式觸控面板，而一般電容式的觸控面板，該觸控面板係於一透明基板底面上設置一氧化銦錫(ITO)層，且底面周緣作為一佈線區，該氧化銦錫層上則形成有複數電極，並於該佈線區上則設置複數導線分別與該複數電極電連接；而由於上述導線為非透明物，因此當製作電子裝置的廠商拿到上述觸控面板時，又必須於一保護板底部周緣塗佈一油墨層，並於上述觸控面板的頂面設置一黏貼層且與該保護板黏合，使該保護板底面油墨層對應觸控面板的佈線區，以將觸控面板佈線區內的導線遮蔽，而油墨層及黏貼層之使用除會對電子裝置的製造廠造成製程及材料成本的問題外，亦會使電子裝置的整體厚度增加，無法滿足可攜式電子裝置輕薄短小的需求，因此整體厚度等缺點勢必需要有所改良。
再者，傳統電容式觸控面板因為解決習知之問題，則將橫軸及縱軸之電極設置於同一平面上，再透過細密之佈線方式，設置兩軸之電極，藉以減少整體厚度，但兩軸之電極相距太近容易產生干擾，再者，容易因距離過進而產生干涉或造成電極短路或訊號干擾等缺點，故習知技術具有下列缺點：
1.製造成本較高；
2.易造成干涉；
3.容易產生訊號干擾。

1. Higher manufacturing costs;
2. Easy to cause interference;
3. It is easy to generate signal interference.
