觸控模組訊號傳輸構造Touch module signal transmission structure

本創作是有關於一種觸控模組中訊號傳輸的構造,可應用在電子產品的觸控面板,或直接製成電子產品上包含觸控面板的上蓋。The present invention relates to a signal transmission structure in a touch module, which can be applied to a touch panel of an electronic product, or directly formed into an upper cover of an electronic product including a touch panel.

近年來,觸控面板逐漸取代傳統的實體按鍵,廣泛應用於手機、數位相機、平板電腦等電子產品上,並且也應用在許多電器的控制面板上。隨著觸控面板之產製技術日漸成熟,觸控靈敏度已大幅提升,加上多點觸控的應用,使其在使用上更加便利,市場上對於觸控面板的需求仍持續攀升。In recent years, touch panels have gradually replaced traditional physical buttons, which are widely used in electronic products such as mobile phones, digital cameras, and tablet computers, and are also applied to control panels of many electrical appliances. As the production technology of touch panels has matured, touch sensitivity has been greatly improved, and the application of multi-touch has made it more convenient to use. The demand for touch panels in the market continues to rise.

前述觸控面板主要是由基板與感應薄膜貼合而成觸控模組,該基板位於觸控面板外側,用以接受使用者觸摸,該感應薄膜則設於基板內面,且感應薄膜上設有複數層觸控感應電路,以及一輸出訊號用的電連接區,當觸控感應電路感應到來自使用者的觸控動作之後,即通過電連接區輸出訊號至電子產品之電路板,以達到觸控之目的。The touch panel is mainly composed of a substrate and an inductive film, and the substrate is disposed outside the touch panel for receiving a touch. The sensing film is disposed on the inner surface of the substrate, and the sensing film is disposed on the sensing film. There are a plurality of layers of touch sensing circuits, and an electrical connection area for outputting signals. When the touch sensing circuit senses a touch action from the user, the output signal is outputted to the circuit board of the electronic product through the electrical connection area. The purpose of touch.

由於上述觸控面板在實務運用時尚需與電子產品結合,而且感應薄膜的電連接區與電子產品的電路板之間必須通過一軟性電路板電性連接;然而感應薄膜裸露在觸控面板的內面,因此在感應薄膜上設置軟性電路板、或觸控面板與電子產品結合組立的過程中,容易碰觸到感應薄膜 而增加損壞的機率,因此本創作人乃設想在感應薄膜內面披覆一基底層,除了能夠保護感應薄膜而提高觸控面板的良率以外,基底層可設計諸如卡扣等構造,以便後續安裝在電子產品時,直接卡扣於電子產品下蓋,讓整體觸控模組可以取代傳統電子產品的上蓋。Since the touch panel is practically used in combination with an electronic product, the electrical connection area of the sensing film and the circuit board of the electronic product must be electrically connected through a flexible circuit board; however, the sensing film is exposed in the touch panel. Therefore, in the process of providing a flexible circuit board on the sensing film or combining the touch panel and the electronic product, it is easy to touch the sensing film. In addition to increasing the probability of damage, the present author conceived to cover a base layer on the inner surface of the sensing film. In addition to protecting the sensing film and improving the yield of the touch panel, the substrate layer can be designed such as a buckle for subsequent use. When installed in an electronic product, it is directly attached to the lower cover of the electronic product, so that the overall touch module can replace the upper cover of the traditional electronic product.

惟,在感應薄膜內面披覆一基底層時,仍須在感應薄膜內面保留電連接區,以供後續感應薄膜與電子產品的電路板電性連接。有鑑於此,本創作人乃進一步提出了本創作觸控模組訊號傳輸構造,以同時克服前述感應薄膜內面裸露、以及感應薄膜與電路板電性連接的問題。However, when the inner surface of the sensing film is covered with a base layer, the electrical connection area must remain on the inner surface of the sensing film for electrically connecting the subsequent sensing film to the circuit board of the electronic product. In view of this, the present author further proposes the signal transmission structure of the present touch module to simultaneously overcome the problem of the exposed inner surface of the sensing film and the electrical connection between the sensing film and the circuit board.

又,目前業界已存在有一種曲面狀電容式觸控面板之技術,例如美國專利第US20100103138A1號、以及台灣專利第I3200073號,可直接將觸控面板製成電子產品之外殼,進而節省生產成本;惟該等先前技術不具有基底層,亦未提供與電子產品之電路板電性連接的解決方案,在實務運用上仍有待改進。Moreover, there is a technology of a curved capacitive touch panel in the industry, such as US Patent No. US20100103138A1 and Taiwan Patent No. I3200073, which can directly form a touch panel into an outer casing of an electronic product, thereby saving production costs; However, the prior art does not have a base layer, nor does it provide a solution for electrically connecting the circuit board of the electronic product, and there is still room for improvement in practical application.
