背景技术Background technique
当非导电性物体本身携带大量电荷（正电荷或负电荷）时，一般需要通过以下几种形式，才能将该物体本身携带的静电荷释放掉：第一种是直接与低电位的导体（或半导体）接触、靠近或接地时，会通过传导方式直接释放；第二种是当带电体携带足够多的电荷时，在与导体（或半导体）靠近的过程中，会选择相互间距离最近的一个尖端瞬间击穿空气（或其它介质）进行放电。第三种是在高湿度环境，即60%RH下，物体本身的静电荷会慢慢被空气中的正负离子中和掉。第一种和第二种方式的特点是瞬间电流非常高，施体和受体都会受到瞬间电击，同时以光或热的形式释放能量。When a non-conducting object itself carries a large amount of charge (positive or negative), it is generally necessary to release the static charge carried by the object itself in the following forms: the first is a direct and low potential conductor (or When the semiconductor is in contact, close to or grounded, it will be directly released by conduction; the second is when the charged body carries enough charge, in the process of approaching the conductor (or semiconductor), the closest distance to each other is selected. The tip instantaneously breaks through the air (or other medium) for discharge. The third is that in a high humidity environment, that is, 60% RH, the static charge of the object itself is slowly neutralized by the positive and negative ions in the air. The first and second modes are characterized by very high instantaneous currents, and both the donor and the receptor are subjected to an instantaneous electric shock while releasing energy in the form of light or heat.
目前，显示器件对静电敏感的电子器件所发生的静电失效，大部分都是前第一种和第二种静电释放形式下所产生的不良。因此，提供一种用于显示器件的抗静电失效装置就很有必要。At present, the electrostatic failure of the display device for electrostatically sensitive electronic devices is mostly caused by the first and second electrostatic discharge forms.

The non-functional traces in the present invention include a plurality of traces such as a ground line (GND), a process test line, and a fill line (block).

当非导电性（半导体或绝缘体）物体本身携带大量电荷（正电荷或负电荷）时，如果直接与低电位的导体接触或接地时，会通过传导方式向导体直接释放能量；如果电压足够大时，可以在与导体逐渐靠近的过程中，向距离最近的一个尖端隔空放电，瞬间击穿空气或其它介质。在这个过程中，如果导体的承受能力不足（过载）时，就会发生电击伤的情况，烧毁线路，造成不可恢复的功能不良。能量过载一般容易发生在不同材质的导电性走线相互搭接的界面，或是同一材质的导线的体电阻阻抗值突然变大的位置，线路突然收窄、转弯或线路材质与前端不同导致的阻抗变化等等情况。When a non-conductive (semiconductor or insulator) object itself carries a large amount of charge (positive or negative charge), if it is directly in contact with or grounded to a low-potential conductor, it will directly release energy through the conduction mode; if the voltage is large enough In the process of gradually approaching the conductor, it can discharge to the nearest tip, and instantaneously penetrate the air or other medium.

本发明的最佳实施方式BEST MODE FOR CARRYING OUT THE INVENTION
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
实施例1Example 1
本实施例提供一种用于显示器件的抗静电失效装置，显示器件用于显示器，显示器件包括功能走线1，位于功能走线1***的非功能性走线2，如图1，所述抗静电失效装置包括至少一组放电尖端组合，相邻的放电尖端组合设置间隙。The embodiment provides an antistatic failure device for a display device. The display device is used for a display. The display device includes a function trace 1 and a non-functional trace 2 located at the periphery of the function trace 1, as shown in FIG. The antistatic failure device includes at least one set of discharge tip combinations in which adjacent discharge tips are combined to provide a gap.
本实施例中，当受到外部静电影响时，最***的放电尖端组合的尖端，会优先将静电导流向远离功能性走线的部位并释放掉，减小对于功能性走线的影响。非功能性走线2最常见的是GND线，还可以是过程测试线、填充线（块）等多种走线。In this embodiment, when subjected to external static electricity, the tip of the outermost discharge tip combination preferentially discharges the static electricity to a portion away from the functional trace, thereby reducing the influence on the functional trace. The most common non-functional trace 2 is the GND line, and it can also be a variety of traces such as process test lines and fill lines (blocks).
具体地，所述放电尖端组合包括至少1个放电尖端4，放电尖端4包括与非功能性走线2导通连接的主体部，还包括与主体一体连接的尖端部；所述尖端部的尖端远离主体部；所述主体部与非功能性走线2之间的夹角β为30°~90°。本实施例中的尖端部为三角形或菱形以及其他可以形成尖端的形状，尖端用于对外部静电的吸引。Specifically, the discharge tip assembly includes at least one discharge tip 4 including a body portion electrically connected to the non-functional trace 2, and further including a tip end portion integrally connected to the body; a tip end of the tip portion The distance between the main body portion and the non-functional trace 2 is 30°~90°. The tip end portion in this embodiment has a triangular shape or a rhombus shape and other shapes which can form a tip end for attracting external static electricity.
优选地，在不影响产品外观及功能的情况下，尽可能的加大放电尖端4的长度；如图4，尖端部的角度a一般选用30～50°，角度设计太小不利于在蚀刻后保持锐利的形状，角度太大时，又不利于对静电的吸引。Preferably, the length of the discharge tip 4 is increased as much as possible without affecting the appearance and function of the product; as shown in FIG. 4, the angle a of the tip portion is generally selected from 30 to 50 degrees, and the angle design is too small to be favorable after etching. Maintaining a sharp shape, when the angle is too large, is not conducive to the attraction of static electricity.
优选地，如图2，所述放电尖端组合内相邻尖端的间距d1≤L/2，其中L为放电尖端4的长度。Preferably, as in Figure 2, the spacing d1 ≤ L/2 of adjacent tips within the combination of discharge tips, where L is the length of the discharge tip 4.
优选地，所述相邻放电尖端组合之间的间隙距离d2≤2w，其中w为显示器件边缘与最***功能线走线之间的距离。例如：当最外侧一条功能走线1距离产品边缘的距离为1mm时，相邻的两组放电尖端4的距离，应该小于等于2mm。Preferably, the gap distance between the adjacent discharge tip combinations is d2 ≤ 2w, where w is the distance between the edge of the display device and the outermost functional line trace. For example, when the distance of the outermost functional trace 1 from the edge of the product is 1 mm, the distance between the adjacent two sets of discharge tips 4 should be less than or equal to 2 mm.
优选地，所述放电尖端组合呈裸露态，所述功能走线1及非功能性走线2上均设置有保护层。Preferably, the discharge tip combination is in a bare state, and the functional trace 1 and the non-functional trace 2 are both provided with a protective layer.
优选地，所述保护层为绝缘层或半导体层。Preferably, the protective layer is an insulating layer or a semiconductor layer.
本发明中的放电尖端4不限于以均匀的、渐变的或突变的尺寸进行设计的方式。同一组内相邻的两条走线之间的间距，不限于最优的小于等于放电尖端4长度的1/2，相邻两组引线之间的间距，不限于最优的小于最外侧功能线与边缘之间距离的两倍；放电尖端4的数量不限于以一条或若干条为一组的形式间隔（等距或不等距）排列，或以无规则的间距进行不同数量的引线设计。The discharge tip 4 in the present invention is not limited to the manner of designing in a uniform, gradual or abrupt size. The spacing between two adjacent traces in the same group is not limited to an optimum one or less than 1/2 of the length of the discharge tip 4, and the spacing between adjacent two sets of leads is not limited to the optimal less than the outermost function. The distance between the line and the edge is twice; the number of the discharge tips 4 is not limited to being arranged in a form of one or several strips (equal or unequal), or different numbers of lead designs at random intervals. .
放电简单尖端部外的部分，不限于以均匀线条的形式或异型的形式进行设计；当***GND走线或其它非功能走线（填充线、过程测试线或内层防静电线等等）1相邻时，可以同时进行内、外两层静电尖端的二级防护形式设计。The part outside the simple tip of the discharge is not limited to being designed in the form of uniform lines or in the form of a profile; when the peripheral GND traces or other non-functional traces (fill lines, process test lines or inner antistatic lines, etc.) 1 When adjacent, the secondary protection form of the inner and outer layers of the electrostatic tip can be simultaneously designed.
放电尖端组合是需要作为导体，用于吸引或引导带电物体静电电荷在指定的方向上传导和释放。因此，在本发明中关于防静电引线及尖端的设计，是需要裸露出来的，放电效果最佳。但是，如果采用其它材料对引线及尖端实施全部或部分尺寸的覆盖或保护时，产品的防静电效果就会有所下降，但是仍然对产品的抗静电性发挥一定的作用。The discharge tip combination is required as a conductor for attracting or guiding the electrostatic charge of the charged object to conduct and release in a specified direction. Therefore, in the present invention, the design of the antistatic lead and the tip is required to be exposed, and the discharge effect is optimal. However, if other materials are used to cover or protect the lead and the tip in all or part of the size, the antistatic effect of the product will be reduced, but it will still play a certain role in the antistatic property of the product.
本实施例中，针对引线及尖端之外部分的保护设计，为了更好的保护功能走线1，对功能走线1可以采用不同的工艺及绝缘性或半导体材料进行覆盖时，会起到更好的防静电性能。In this embodiment, for the protection design of the lead and the outer portion of the tip, in order to better protect the function trace 1, the function trace 1 can be covered by different processes and insulation or semiconductor materials. Good antistatic performance.
基于IEC61000-4-2标准进行测试，一般LCD产品（贴合前）的抗静电能力在±6~±8KV左右，OLED产品（贴合前）的抗静电能力在±2~±4KV左右，TP产品（贴合前）的抗静电能力在±6~±8KV左右；原因主要有两个：一个是器件结构决定的，一个是虽然有采用简单的ESD设计，但实际上发挥的效果并不显著，导致产品的抗静电性能不佳。本实施例可将OLED产品的空气放电抗静电性能提高到±8KV以上，LCD的的空气放电抗静电性能提高到±15KV以上，TP的空气放电抗静电性能提高到±12KV以上。Based on the IEC61000-4-2 standard test, the antistatic ability of general LCD products (before lamination) is about ±6~±8KV, and the antistatic capability of OLED products (before lamination) is about ±2~±4KV, TP The antistatic ability of the product (before bonding) is about ±6~±8KV; there are two main reasons: one is determined by the device structure, and the other is that although the simple ESD design is adopted, the effect is not significant. , resulting in poor antistatic properties of the product. In this embodiment, the air discharge antistatic performance of the OLED product can be improved to ±8KV or more, the air discharge antistatic performance of the LCD is improved to ±15KV or more, and the air discharge antistatic performance of the TP is improved to ±12KV or more.
