在IPhone掀起了一波多點觸控熱潮後,投射電容式觸控面板也將取代電阻式觸控面板成為中小尺寸手持式行動裝置與平板電腦的應用主流,但因為需搭配外觀設計上的特性導致其成為高度客製化之產品,且成本高昂,故業界發展出非常多種結構之製程,各有其優劣,而如玻璃貼合玻璃此種硬對硬的光學貼合技術,更是近幾年內的新技術,故技術並不成熟,且材料搭配皆會影響貼合製程,而此一貼合技術在觸控模組生產良率上佔了極重要的比例,控制得宜可以大幅提升良率,增加獲利。本篇論文即針對液態膠之貼合製程改良為研究主題。 本研究結果顯示確實能夠改善現有之液態膠貼合製程盲點,並且提升產能與良率,但僅管產能與良率提升,其貼合設備之產能效益比較起與日俱增的投射電容式觸控面板需求並不盡理想,故未來將以全自動化高速貼合做為研究目標,以其能夠達到更高效能之生產。
Capacitive Touch Panel, replaced Resistive Touch panel, becomes the main stream application in medium size handheld equipment and Tablet PC after iPhone started the fashion of multi-touch. However, due to the highly requirement in customize design to accommodate various ID design, there are many different process developed, and there are also pros and cons out from those different structure process. And for the lamination process on glass to glass, using optical liquid gel, is the newest technology developed during these years. Nevertheless, this new technology is not yet reaching to a mature stage, not to mention the variance in different material causing low yield rate owing to many kinds of process issues. To reach high yield rate in the lamination process means to reach cost incentive in touch panel cost structure. Therefore, this essay is aimed to study on how to improve the lamination process using optical liquid gel.
