本发明是关于一种触控面板，尤指一种可降低感测垫的可视性的电容式触控面板。The present invention relates to a touch panel, in particular to a capacitive touch panel capable of reducing the visibility of a sensing pad.
【背景技术】【Background technique】
触控面板由于具有人机互动的特性，已逐渐取代键盘而被广泛应用于电子装置的输入介面上。近年来，随着消费性电子产品的应用面发展越来越广，将触控面板与显示器结合而形成触控显示装置的应用产品也越来越多，包括移动电话(mobile phone)、卫星导航系统(GPS navigator system)、平板电脑(tablet PC)以及笔记型电脑(laptop PC)等。Due to the characteristic of human-computer interaction, the touch panel has gradually replaced the keyboard and is widely used in the input interface of the electronic device. In recent years, as the application of consumer electronic products has become more and more extensive, there are more and more application products that combine touch panels and displays to form touch display devices, including mobile phones, satellite navigation system (GPS navigator system), tablet PC (tablet PC) and notebook computer (laptop PC), etc.
根据触控机制的不同，触控面板主要可以区分为电容式触控面板、电阻式触控面板与光学式触控面板等类型，其中电容式触控面板为现行触控面板的主流产品。已知电容式触控面板包括一透明基板、一透明感测图案设置于透明基板上，以及一保护层覆盖透明基板与感测垫。透明基板例如为玻璃基板，透明感测图案的材料例如为氧化铟锡(ITO)，而保护层可为例如氧化硅层。由于透明感测图案具有高折射率，其与透明基板以及保护层的折射率的差异颇大，因此会造成使用者在目视上容易看出相邻的感测垫之间隙。特别是在触控面板应用在显示面板上时，相邻的感测垫之间隙的可视性会严重影响显示面板所提供的显示画面，而导致显示效果不佳。According to different touch mechanisms, touch panels can be mainly divided into capacitive touch panels, resistive touch panels, and optical touch panels, among which capacitive touch panels are the mainstream products of current touch panels. A known capacitive touch panel includes a transparent substrate, a transparent sensing pattern disposed on the transparent substrate, and a protective layer covering the transparent substrate and the sensing pads. The transparent substrate is, for example, a glass substrate, the material of the transparent sensing pattern is, for example, indium tin oxide (ITO), and the protection layer can be, for example, a silicon oxide layer. Since the transparent sensing pattern has a high refractive index, the difference between the transparent sensing pattern and the refractive index of the transparent substrate and the protective layer is quite large, so the user can easily see the gap between the adjacent sensing pads visually. Especially when the touch panel is applied on the display panel, the visibility of the gap between adjacent sensing pads will seriously affect the display image provided by the display panel, resulting in poor display effect.
【发明内容】【Content of invention】
