Description

一种单层ITO的布线结构 One-layer wiring structure ITO

技术领域 FIELD

[0001] 本发明涉及一种ITO的布线结构,尤其是指一种单层ITO的布线结构。 [0001] The present invention relates to a wiring structure of an ITO, and particularly to a wiring structure of a single layer of ITO. 背景技术 Background technique

[0002] 所谓ITO (铟锡氧化物)是一种用于生产液晶显示器的关键材料,目前,其在仪器仪表、计算机、电子表、游戏机和家用电器等领域都有了极为广泛的应用。 [0002] called ITO (indium tin oxide), a key material for producing a liquid crystal display, currently, it has a very wide range of applications in instruments, computers, electronic watches, game consoles and home appliances. 近年来市场上大热的电容式触摸屏也是利用ITO来完成侦测触摸的动作,而电容触摸屏上ITO的布线一般是双层,其主要原理是:利用人体电场,当使用者触摸时,表面行或列的交叉处感应单元的互电容(也称耦合电容)会有变化,根据上述变化最终可检测出触摸点的具体位置。 In recent years, the market hot capacitive touch screen is touch detect the use of ITO to complete the action, and the wiring on the ITO capacitive touch screen is generally double, its main principle is: the use of human electric field, when the user touches the surface line induction or at the intersection of column cells mutual capacitance (also called a coupling capacitor) will change, eventually detect the specific location of the touch point according to the above changes.

[0003] 常见的双层ITO的结构是菱形结构,其双层ITO分别布设在玻璃基板的同侧面上, 为了避免电极之间的相互导通,所以需要在玻璃基板上设置桥接点,这样就可将双层ITO 布设在玻璃基板的同一侧面上。 [0003] Common bilayer structure rhombus structure is ITO, ITO bilayer which are laid on the same side surface of the glass substrate, in order to avoid mutual conduction between the electrodes, it is necessary to set the bridging point on the glass substrate, so that ITO bilayer may be arranged on the same side of the glass substrate. 虽然上述方法实现了侦测触摸的动作,但是这种采用双层ITO的触摸屏结构,不但工艺复杂,而且桥接处容易损坏,产品良率低,导致成本升高。 Although the above-described method enables to detect a touch operation, but the touch screen ITO bilayer structure, not only complex process, but may also damage the bridge, the low yield of products, an increase in cost. 为了克服上述缺点,部分厂商将ITO的结构设置成矩形,然后双面设置在玻璃基板的两层,如此以来,工艺的确的简单了很多,而且提高了产品良率,但是仍旧采用的是双层ITO的布线结构,ITO本身成本就较高,再加上双层的结构,使由此形成触摸屏的厚度也就增加了。 In order to overcome the above drawbacks, some manufacturers will ITO arranged in a rectangular configuration, two layers of glass and a double-sided substrate provided, so since the process does a lot simpler, but also improve the product yield, but still uses a double ITO wiring structure, high cost of ITO itself, plus the bilayer structure, the thickness of the touch screen thus formed is also increased. 如果能够克服双层ITO布图结构带来的局限性,所以无论是从成本上还是触摸屏的结构上考虑, 单层ITO均具有更多优势。 If you can overcome the limitations caused by double-ITO layout structure, so it is still considering the cost structure from the touch screen, single-layer ITO has more advantages.

[0004] 因此需要为广大用户提供一种更加简便的ITO的布线结构来解决以上问题。 [0004] Therefore, the need to provide customers with a more convenient wiring structure ITO to solve the above problem. 发明内容 SUMMARY

[0005] 本发明实际所要解决的技术问题是如何提供一种工艺简单,成本低廉的单层ITO 的布线结构。 [0005] The present invention is actually solving the technical problem is how to provide a simple process, low cost single layer wiring structure of ITO.

[0006] 为了实现本发明的上述目的,本发明提供了一种单层ITO的布线结构,其由多个正负触控电极组成,所述正负触控电极的一条边缘上设有一个凸起。 [0006] To achieve the above object of the present invention, the present invention provides a wiring structure of a single layer of ITO, which is composed of a plurality of positive and negative strip electrodes, is provided with a projection on one edge of the touch electrode negative play. 本发明所述的单层ITO 的布线结构,相对双层ITO的布线而言,制造工艺更加简单,所以成本低廉;再者,由单层ITO组成的触摸屏厚度较薄,功能上相互匹配性能好。 ITO single layer wiring structure according to the present invention, the wiring of the relative double ITO, the manufacturing process more simple, low cost; Furthermore, the thickness of the touch screen of a single layer of ITO thin, functional performance is good match with each other .
