Description

觸控面板之製造方法
本發明係有關於一種觸控面板之製造方法,尤指一種可降低組裝成本與節省組裝時間之觸控面板之製造方法。
隨著資訊技術與通訊網路的迅速發展,電子資訊產品漸漸普及於個人,相對的觸控面板也同時迅速發展,現今觸控面板依其感應原理的不同,主要區分為電阻式、電容式、電磁式以及光學式等四種,其中電容式觸碰面板結構具防塵、防火以及高解析度等特性,因而廣泛地被採用,該電容式觸控面板作用原理,主要是依據電容量變化來確認接觸點位置,利用觸控物(如手指等導體)的接近對電極間產生電容性的電性變化,而確定接觸點的座標。
而電容式觸控面板也漸漸的成為觸控技術中的主流,並應用在各項電子資訊產品當中,例如手機、平板電腦、隨身聽、手持式電子裝置(設備)、各種顯示器、監視器等等,該等電子資訊產品其原理為應用手指接觸觸控面板時所造成之電容值變化以測得手指之位置變化與點選狀況,進而達成操控之目的。
但一般電容式觸控面板在黏合組裝上,通常需要顧慮黏合之問題,因使用光學膠脂 (OCR, Optical Clear Resin)或光學膠 (OCA, Optical Clear Adhesive)黏合後,通常需要另外一道加工進行整理溢膠的問題,相對也提高其組裝成本與組裝時間之問題,以上所述,習知技術中具有下列的缺點:
1.組裝成本高;
2.耗費組裝時間;
3.不良率高。
是以,要如何解決上述習用之問題與缺失,即為本案之發明人與從事此行業之相關廠商所亟欲研究改善之方向所在者。
爰此,為有效解決上述之問題,本發明之主要目的在提供一種可降低組裝成本與節省組裝時間之觸控面板之製造方法。
為達上述目的,本發明係提出一種觸控面板之製造方法,其包括下列步驟:
提供一形成有至少一延伸部及由延伸部界定有一容置空間之背光模組;

先提供一黏合層貼合所述液晶顯示層及電容式感應層;
將貼合之液晶顯示層及所述電容式感應層設置於所述容置空間內。
透過本發明之觸控面板之製造方法,其黏合層貼合所述液晶顯示層與電容式感應層再設置於所述容置空間內,且其液晶顯示層與電容式感應層兩側係分別貼附所述延伸部,因此,其黏合層於液晶顯示層與電容式感應層側邊所形成之外溢區域可經由所述背光模組周邊之延伸部擋止,進而減少需另外去除外溢區域之動作,藉以達到降低組裝成本與節省組裝時間及提高良率之功效。
