触控电路图的制作方法How to make touch circuit diagram

技术领域technical field

本发明涉及一种触控电路的制作方法，特别是一种在玻璃基板表面上形成触控电路图的制作方法。 The invention relates to a method for manufacturing a touch circuit, in particular to a method for forming a touch circuit diagram on the surface of a glass substrate. the

背景技术Background technique

触控板(Touch Panel)已大量运用于家电、通讯、电子资讯等产品上，例如目前广泛商用的个人数位助理(PDA)、各种家电设备和游戏输入介面等，一般都是由触控板与显示面板整合而成，可供使用者用手指或触控笔依照显示画面上的功能选项点选输入所要执行的动作，并且还被利用到大众系统查询工具上，可以提供便民效果的工作系统。 Touch panels have been widely used in home appliances, communications, electronic information and other products, such as personal digital assistants (PDAs), various home appliances and game input interfaces that are currently widely used. Integrated with the display panel, users can use their fingers or stylus to click and input the action to be performed according to the function options on the display screen, and it is also used in the public system query tool, which can provide a convenient working system . the

一般的触控板是在一基板表面布设感应区域，其感应区域用来感应人体的手指或感应笔的触控信号，该感应区域所使用的材料大都采用透明导电薄膜(例如氧化铟锡ITO)，使得使用者在操作时，由触压透明导电薄膜对应显示面板上相对应画面，达到触控的功能。 A general touch panel is to lay out a sensing area on the surface of a substrate. The sensing area is used to sense the touch signal of the human finger or the sensor pen. Most of the materials used in the sensing area are transparent conductive films (such as indium tin oxide ITO). , so that the user can touch and press the transparent conductive film corresponding to the corresponding screen on the display panel to achieve the touch function during operation. the

目前所常采用的触控原理概可分为电阻式、电容感应式、红外线感应式、电磁感应式和音波感应式等。其中电容感应式触控板的工作原理是利用排列的透明电极与人体之间的静电结合所产生的电容变化，从而产生的诱导电流来检测其触控位置的坐标，来实现工作的。由于电容感应式触控板在透光度、硬度、准确率、反应时间、触控打点寿命、操作温度、和起始力量各方面都具有明显的优点，所以目前大量采用。 Currently, the commonly used touch control principles can be divided into resistive, capacitive, infrared, electromagnetic and sonic sensing. Among them, the working principle of the capacitive sensing touch panel is to use the capacitance change generated by the electrostatic combination between the arranged transparent electrodes and the human body, thereby generating an induced current to detect the coordinates of the touch position to realize the work. Since the capacitive touch panel has obvious advantages in light transmittance, hardness, accuracy, response time, touch point life, operating temperature, and starting force, it is widely used at present. the

为了要侦测出使用者用手指或感应笔触碰于触控板上的位置，现在与研发出各种不同的电容式感应触碰感测技术。例如：在美国专利第6970160号发明专利案中，揭露了一种格状触控感应系统，其可应用于侦测一触控感应面的触控位置。格状触控感应系统包括两个电容感应层，其间以一中间隔绝材料分隔，形成电容效应。每一电容感应层包括平行排列的导电元件。两个电容感应层彼此垂直。每一个导电元件包括一序列的菱形片，由狭窄的导电线连接在一起。每一电容感应层上的导电元件电连接一导线。一控制电路透过导线提供讯号传至两组导电元件上，能在表面被触按时接收由感应元件所产生的感应讯号，以判断在每一层的触控位置。 In order to detect where a user touches a touch panel with a finger or a stylus, various capacitive touch sensing technologies have been developed. For example, in US Patent No. 6970160, a lattice touch sensing system is disclosed, which can be applied to detect the touch position of a touch sensing surface. The lattice touch sensing system includes two capacitive sensing layers separated by an intermediate insulating material to form a capacitive effect. Each capacitive sensing layer includes conductive elements arranged in parallel. The two capacitive sensing layers are perpendicular to each other. Each conductive element consists of a sequence of diamond-shaped pieces connected together by narrow conductive lines. The conductive elements on each capacitive sensing layer are electrically connected to a wire. A control circuit provides signals to two groups of conductive elements through wires, and can receive the induction signals generated by the sensing elements when the surface is touched, so as to determine the touch position on each layer. the

但是，上述技术必须分别通过二次的离子真空溅镀、曝光、显影及蚀刻等制程，才能布设形成二层透明导电薄膜(举如ITO)于一玻璃基板表面上，造成制程上繁琐的问题，增加了制作成本，降低了生产率。 However, the above-mentioned technology must go through two processes of ion vacuum sputtering, exposure, development and etching respectively, so as to form a two-layer transparent conductive film (such as ITO) on the surface of a glass substrate, which causes cumbersome problems in the process. Increased production cost, reduced productivity. the
