Description
本發明涉及一種觸控顯示裝置的軟性電路板結合方法及觸控顯示裝置。 The invention relates to a flexible circuit board bonding method and a touch display device of a touch display device.
隨著平板顯示技術的蓬勃發展及製造成本的日益降低，具有輻射低、厚度小、功耗低等優點的平板顯示裝置越來越受到消費者的青睞，因此被廣泛地應用在電子產品中。為了符合現代人對於更加便利、更加直觀的人機界面的需要，近年來市場上逐漸推出各種各樣具有觸控功能的平板顯示裝置，即觸控顯示裝置。通常，觸控顯示裝置可分為外置式和內嵌式兩種。其中，外置式觸控顯示裝置在傳統的平板顯示裝置基礎上附加一觸控面板；而內置式觸控顯示裝置是直接將觸控面板通過內嵌的方式整合至顯示面板(比如液晶面板)之中。目前的外置式觸控面板種類繁多，包括電阻式、電容式、紅外線式和表面聲波式等多種類型。 With the rapid development of flat panel display technology and the decreasing manufacturing cost, flat panel display devices with low radiation, small thickness and low power consumption are increasingly favored by consumers, and thus are widely used in electronic products. In order to meet the needs of modern people for a more convenient and more intuitive human-machine interface, various flat panel display devices with touch functions, namely touch display devices, have been gradually introduced in the market in recent years. Generally, the touch display device can be divided into an external type and an in-line type. The external touch display device is provided with a touch panel on the basis of the conventional flat display device; and the built-in touch display device directly integrates the touch panel into the display panel (such as the liquid crystal panel) through the embedded method. in. At present, there are many types of external touch panels, including resistive, capacitive, infrared, and surface acoustic wave types.
習知觸控顯示裝置的觸控面板(如電容式觸控面板)通常包括導電層、與導電層電連接的電極或周邊線路及覆蓋該導電層、電極或周邊線路的保護層。為實現觸控面板與外部驅動電路的電連接，需要一軟性電路板一方面與該電極或周邊線路結合(bonding)，另一方面電連接至外部驅動電路(如印刷電路板)。 A touch panel (such as a capacitive touch panel) of a conventional touch display device generally includes a conductive layer, an electrode or a peripheral line electrically connected to the conductive layer, and a protective layer covering the conductive layer, the electrode or the peripheral line. In order to realize the electrical connection between the touch panel and the external driving circuit, a flexible circuit board is required to be bonded to the electrode or the peripheral circuit on the one hand, and to an external driving circuit (such as a printed circuit board) on the other hand.
在軟性電路板與觸控面板的結合過程中，首先需要將覆蓋在電極或周邊線路的保護層通過蝕刻製程去除，再將軟性電路板對應該觸控面板的電極或周邊線路的壓合。然而，該保護層通常特性比較穩定，不易蝕刻，比如：當採用二氧化矽作為保護層時，通常需採用氫氟酸蝕刻製程或者光罩製程去除覆蓋電極或周邊線路的二氧化矽，這些製程花費大量人力物力，從而導致習知觸控顯示裝置的軟性 電路板的結合製程複雜、成本較高。 In the process of combining the flexible circuit board and the touch panel, the protective layer covering the electrode or the peripheral circuit is first removed by an etching process, and then the flexible circuit board is pressed against the electrode of the touch panel or the peripheral circuit. However, the protective layer is generally stable in characteristics and difficult to etch. For example, when ruthenium dioxide is used as the protective layer, it is usually necessary to remove the ruthenium dioxide covering the electrode or the peripheral line by a hydrofluoric acid etching process or a mask process. A lot of manpower and material resources are spent, resulting in the softness of the conventional touch display device The combination process of the circuit board is complicated and the cost is high.
