单层ITO的布线结构 ITO single layer wiring structure of

技术领域 FIELD

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

[0002] 近来,随着触控技术的不断发展,人们对其使用的触控屏的要求越来越高,不但外观要求更加炫丽,而且其价格也趋于降低。 [0002] Recently, with the development of touch technology, touch screen requires people to use their increasingly high requirements not only look more dazzling, and its price tends to decrease. 为了降低成本的因素,越来越多的设计公司采用了单层ITO来代替传统的两层ITO组成的触控屏,由于ITO本身价格较贵,且将两层ITO布设在触控屏上的工艺复杂,所以利用单层ITO的触控屏不仅仅是价格上更具优势,其较为简单的工艺步骤也成了触控屏未来发展的一大趋势。 In order to reduce the cost factor, an increasing number of design companies using a single-layer ITO touch screen instead of the traditional two layers of ITO and ITO itself because the price is more expensive, and the two layers arranged on the ITO touch screen complex process, so the use of a single layer ITO touch screen is not only more competitive on price, which is a relatively simple process steps touch screen has become a major trend of future development.

[0003] 现阶段,单层触控屏上所采用的ITO的布图一般是三角形或者矩形。 [0003] stage, ITO layout on the touch screen monolayer with general triangular or rectangular. 对于三角形而言,由于是通过两个对称的三角形组成一组电极组分别布设在ITO层上,所以对所述触控屏的大小就有一定的限制,随着三角形角度的逐渐递减,触控对象如手指触碰的位置就不能快速的分辨,从而不能准确的判断触控点的具体位置坐标。 For triangle, since two symmetrical triangles by a set of electrodes are arranged on the set of the ITO layer, so there is a certain limit on the size of the touch screen, with gradually decreasing angle of the triangle, the touch the finger touch position of the object can not be quickly resolved, and thus can not accurately determine the specific position coordinates of the touch point. 而对于矩形而言,是由若干个矩形状的电极块布设在ITO层上,由于各个电极块相互独立引出各个导线连接到触控屏上芯片的相应扫描引脚上,所以手指在任何一处都可以准确的判断其具体位置,但是由于触控屏上芯片中扫描引脚的限制,设计师们必须综合考虑触控屏幕的大小,才能确定出矩形的尺寸。 For rectangular, the electrodes are laid by a plurality of rectangular blocks on the ITO layer, since the respective lead-out electrode blocks independently of each conductor pin is connected to the corresponding scanning touch screen on the chip, so that at any one finger It can accurately determine its location, but because of restrictions on the touch screen to scan the chip pin, designers must consider the size of the touch screen in order to determine the size of the rectangle. 而对于大屏幕触控屏而言,在扫描引脚一定的情况下,触控屏幕越大,对于的矩形结构也应该越大。 And for large-screen touch screen, scanning pin in certain circumstances, the greater the touch screen for the rectangular structure should also be greater. 如此以来,若矩形的面积大于正常手指触碰点的面积时,手指在触控屏上移动划线时,就可能出现断线的情况。 So since, if the area is larger than the area of ​​a rectangle normal finger touch points, crossed fingers move, it could disconnection appears on the touch screen. 之所以出现上述状况,一个重要的原因就是手指在触控屏上移动时,两个矩形状的电极块相互之间没有产生耦合电容。 The reason why the above-described situation, an important reason is that the finger is moved on the touch screen, a coupling capacitance is not generated between the two rectangular blocks each electrode.

[0004] 为了解决上述可能出现的断线问题,因此需要为广大用户提供一种新的单层ITO 的布线结构来解决以上问题。 [0004] To solve the above problems may arise breakage, it is necessary to provide customers with a new single-layer 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可避免在划线时出现断线问题的单层ITO的布线结构。 [0005] The practice of this invention to solve the technical problem of how to provide a single-layer wiring structure can prevent disconnection of ITO problem occurs when the crossed.

[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,单层ITO的布线结构,所述单层ITO上设有若干电极块,形成若干纵行和纵列,所述电极块的至少一边呈波浪状。 [0006] To achieve the above object of the present invention, the present invention provides a wiring structure of a single layer of ITO, a wiring structure of a single layer of ITO, a plurality of electrodes provided on said single block of ITO, forming a plurality of longitudinal rows and columns , at least one side of the electrode blocks wavy.

[0007] 本发明所述的单层ITO的布线结构,不但简单,而且在一个方向上相邻电极块之间呈波浪状,手指在其上移动时更容易产生耦合电容,从而利于侦测触碰点的位置,克服了再触控屏上划线时出现断线的问题。 [0007] The wiring structure of the present invention is a single layer of ITO is not only simple, but also between the electrode block adjacent wavy in one direction, the finger is more likely to occur when the coupling capacitance movement thereon, thereby facilitating detection contact touch position of a point, to overcome the problems that occur when disconnected again crossed the touch screen.

附图说明 BRIEF DESCRIPTION

[0008] 图1是根据本发明所述单层ITO的结构示意图。 [0008] FIG. 1 is a schematic structure according to the present invention, a single layer of ITO. 具体实施方式 Detailed ways

[0009] 下面结合附图和实施例对本发明作进一步的说明。 Drawings and embodiments of the present invention will be further described [0009] below in conjunction.

[0010] 本发明所述的单层ITO的布线结构,请参考图1所示,所述单层ITO 1上设有若干电极块11,形成若干纵行和纵列,即每个纵行或者纵列均由复数个触控电极块11组成。 [0010] ITO single layer wiring structure according to the present invention, refer to the figure, the single layer is provided with an ITO electrode on a plurality of blocks 11 are formed a plurality of longitudinal rows and columns, i.e. each wale or tandem electrodes by a plurality of blocks 11 composed of a touch. 所述电极块11的各个形状不完全相同,其包括两种,一种是一边呈波浪状的电极块111,另一种是两边均呈波浪状的电极块112,即所有电极块11中至少一边呈波浪状,且所述波浪状的波形可以是三角形或者是弧形。 The respective shape of the electrode block 11 are not identical, which comprises two types of wavy side electrode block 111, and the other is an electrode on both sides of the block 112 are wavy, i.e. at least all electrode blocks 11 wavy side, and the undulating waveform may be triangular or arcuate. 所述各个电极块11上引出导线连接到触控屏上相应芯片(未表示)的引脚上。 The lead-out wires to the pins on the touch screen corresponding chip (not shown) on the respective electrode block 11.

[0011] 所述在一个方向上的两个电极块11之间呈波浪状的各边相向设置,其中,两边均呈波浪状的电极块112位于一边呈波浪状的两电极块111之间,并形成电极组。 [0011] The wavy blocks between the two electrodes 11 in a direction facing each side is provided, wherein the electrodes on both sides of the block 112 are wavy electrode block 111 is positioned between the two side wavy, and forming an electrode group. 所述两边均呈波浪状的电极块112的波形与一边呈波浪状的电极块111的波形图形相同,间隙相等且相互平行;再者,一边呈波浪状的电极块111的波形向下延伸时,与其相对接的两边均呈波浪状的电极块112的波形也是向下延伸,即两者的方向始终相同。 The electrode blocks are wavy same waveform pattern and waveform wavy side electrode block 111 on both sides 112, equal and parallel gap; Furthermore, while waveform wavy electrode block 111 extends downwardly , both sides opposed thereto into contact electrode wavy waveform block 112 also extends downwardly, i.e., both the direction is always the same. 所述电极组中,所有电极11的面积均相等,即一边呈波浪状的电极块111的相互面积相等,两边均呈波浪状的电极块112的相互面积相等,且一边呈波浪状的电极块111与两边均呈波浪状的电极块112 的面积也相等。 The electrode group, the area of ​​all the electrodes 11 are equal, i.e., equal to the area of ​​each side of the wavy electrode block 111, both sides are equal to each other wavy electrode block area 112 and the side electrode blocks wavy 111 and both sides of the wavy area of ​​the electrode block 112 are equal.

[0012] 所述单层ITO 1扫描时,逐次扫描纵行和纵列,每次同时扫描两行或者两列中相邻的两个电极块11,并获取其差值。 [0012] The single layer ITO 1 scan, and successive wales column scanning, each two scan lines at the same time or two electrodes in two adjacent blocks 11, and to obtain the difference. 本发明中设单层ITO层1有A列,先扫描纵列时,首先扫描第一列中第一个电极块111和第一列中的第二个电极块112,且其中第一个电极块111 作为扫描端,第二个电极块112作为参考端,此时其它电极块11均悬空或者接地;第二次扫描时,扫描第一列中第二个电极块112和第一列中的第三个电极块112,且其中第二个电极块112作为扫描端,第三个电极块112作为参考端,此时其它电极块11均悬空或者接地;依次顺序扫描直到扫描A列为止。 In the present invention, there is provided a single layer of ITO column A, column when the first scan, the scan of a first block of the first column electrode 111 and the second electrode block 112 in the first column, and wherein the first electrode as the end of the scanning block 111, a second electrode block 112 as a reference side, then the other electrodes are floating or grounded blocks 11; the second scan, scanning in the first row and the first column of the second electrode block 112 The third electrode block 112 and block 112 wherein the second electrode as a scanning end, the third block 112 as a reference electrode terminal 11 at this time other electrodes are floating or grounded blocks; sequentially scanned until the scan sequence A column.

[0013] 按照上述扫描方式,任意相邻两个电极块11之间由于波浪状的设计,所以手指在移动时会很容易产生耦合电容,所以可以快速的判断出手指在触控屏上的操作动作。 [0013] according to the scanning mode, because any adjacent wavy design, it will be very easy to produce the fingers coupling capacitance electrode moves between the two blocks 11, it is possible to quickly determine the operator's finger on the touch screen action. 对本发明而言,在横向上,由于电极块可以较窄,所以手指从一个电极块11滑向另一个电极块11时,由于手指不会完全在一个电极块11中滑动,所以两者之间产生的耦合电容就能准确的判断出手指滑动的位置;而在纵向上,若电极块较长,手指可能在一个电极块11中滑动一段距离,如此以来就不能侦测此时手指在此段滑动时的具体位置。 For the present invention, in the lateral direction, since the electrode block may narrow, a finger electrode slide block 11 from another electrode block 11, since the finger does not fully block one electrode 11 slides, so that between the two generated by the coupling capacitance can accurately determine the position of the finger sliding; in the longitudinal direction, if the block is longer electrodes, one electrode finger may slide a distance block 11, since it can not detect such a finger during this case the specific position of the slide. 因此,若电极块11相对的至少一边是波浪状的设置,即使触控屏的尺寸较大,而触控屏上芯片引脚的数量又有限,也可以通过所述波浪状的弧度来调整手指纵向移动时两个电极块11之间的电容。 Accordingly, when the electrode block 11 opposed to the at least one side is wavy provided, even a large size touch screen, the touch screen and the number of chip pins and limited, a finger may be adjusted by the undulating curvature the capacitance between the two electrode blocks 11 move longitudinally. 为了更加便捷的判断出手指移动时的具体位置,优先选择将电极块11的波形设置成各边相等。 For more convenient when it is determined that the specific position of the finger movement, the waveform of the electrode block 11 is arranged to preferentially select each of the equal sides.

[0014] 由于当手指纵向移动时,任意两个相邻的电极块11之间都可以产生耦合电容,因此可以侦测手指滑动时的具体位置。 [0014] Since when a finger is moved longitudinally, any two adjacent electrodes can produce blocks between the coupling capacitance 11, it is possible to detect the specific position of the finger sliding. 所以本发明所述的单层ITO的结构通过感应电容的补偿实现了侦测手指滑动时的各个位置坐标。 Therefore, the structure of a single layer of ITO to the present invention achieves the position coordinates of the respective detected finger slides through the sensing capacitor compensation. 如此以来,无论手指是在横向还是纵向上划线, 都可以侦测出两电极块11之间的耦合电容,从而能够避免在触控屏上划线时出现断线的问题。 By so doing, whether the finger is in the horizontal or vertical scribe line, can detect the coupling capacitance between the two electrode blocks 11, it is possible to avoid the problem of disconnection when streaked on the touch screen.

[0015] 本发明所述的单层ITO的布线结构,将电极块的至少一边设置成波浪状,所以增加了电容补偿,避免了手指在划线时可能出现断线的问题。 A wiring structure according to the invention [0015] This single layer of ITO, the electrode block at least one side is provided a wave shape, the capacitance increases to compensate, avoiding the problem of a finger break may occur during scribing. 本发明所述的电极块其形状可以是至少一边呈波浪状的任何规则多边形;再者,对于呈波浪状的电极块也是根据手指的大小不断调整从而找出最适当的曲线弧度,以满足产生的耦合电容。 Any rule electrode block according to the present invention may be a shape which at least one side of a polygonal wavy; Also, for the wavy electrode block is also continuously adjusted in order to identify the most appropriate according to the size of the finger curvature curves to meet produce coupling capacitance.
