Description

一种触摸屏感测图案及电容式触摸传感器
本申请要求于2016年5月20日提交中国专利局、申请号为201620466110.1，发明名称为“一种触摸屏感测图案及电容式触摸传感器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及触摸屏技术领域，尤其涉及一种触摸屏感测图案及电容式触摸传感器。
背景技术
电容触摸屏包括传统的独立电容触摸屏和整合型电容触摸屏，整合型电容触摸屏将触摸传感器加入显示模组，可以实现轻薄化，因此更加符合智能终端的发展趋势。
整合型电容触摸屏一般分为Oncell与Incell两种叠构。参见图1，目前Oncell叠构整合型电容触摸屏的触摸传感器大多采用电容式单层电极图案的方式来制作。第一方向电极为Y1，Y2，Y3，第二方向电极为X1，X2，X3，X4，X5，X6。第一方向电极可以是驱动电极，对应的第二方向电极为感应电极；反之，第一方向电极可以是感应电极，对应的第二方向电极为驱动电极。
驱动电极和感应电极构成感应单元，感应单元需要通过走线引出到触摸屏的屏体边缘，以便与外部电路连接。感应单元中感应电极与出线端的距离累加驱动电极与出线端的距离通常称为感应单元与出线端的距离。以图2左侧第一列为例，感应单元依次为：
Y1X1，Y1X2，Y2X2，Y2X1，Y3X1，Y3X2。
由于感应单元的走线较细，且走线的电阻率较高，因而距离出线端较远的感应单元的走线阻抗要比距离出线端较近的感应单元的走线阻抗要高出许多。触摸传感器的驱动信号传输到感应单元的出线端的过程中，由于走线阻抗会有衰减，这样就导致了距离出线端较远的感应单元与距离出线端较近的感应单元对驱动信号的衰减程度不一样。特别是距离出线端较远的感应单元的衰减比较大，严重降低了整个触摸传感器的信噪比水平。
因此，如何提高电容触摸屏的信噪比，保证触摸能被有效正确的检测出来成为现有技术中亟需解决的技术问题。

由于第二感应单元32中感应电极与出线端的距离累加第二感应单元32中驱动电极与出线端的距离大于第一感应单元31中感应电极与出线端的距离累加第一感应单元31中驱动电极与出线端的距离，第二感应单元32的走线长度大于第一感应单元31的走线长度，从而造成的第二感应单元32的走线阻抗衰减，降低了整个触摸传感器的信噪比水平。
本申请所述第二感应单元32由触摸引起的感应电容的变化量大于所述第一感应单元31由触摸引起的感应电容的变化量，从而抵消第二感应单元32的走线阻抗衰减，提升第二感应单元32的信噪比，保证触摸能被有效正确的检测出来。

本申请充分利用了第二组连续排列的感应单元112走线位置附近因走线数量减少，在走线位置附近存在的剩余空间，通过增大所述第二组连续排列的感应单元112中感应电极和驱动电极的宽度和，和/或，面积和，将所述第二组连续排列的感应单元112走线位置附近存在的剩余空间填充为感应单元，使之能够感应触摸，减少了感应盲区，提升了感应准确度。因此，本申请可以在不增加成本的同时，更加有效的检测触摸，提高检测位置的准确度。
在本申请另一具体实现方式中，参见图12，由于所述第二组连续排列的感应单元122的走线长度和大于所述第一组连续排列的感应单元121的走线长度和，所以所述第二组连续排列的感应单元122的走线阻抗衰减和大于所述第一组连续排列的感应单元121的走线阻抗衰减和。
交叉齿数是指感应电极和驱动电极呈锯齿状交叉，单位面积锯齿的数量。本实施例所述每组连续排列的感应单元中各感应单元的感应电极和驱动电极的交叉齿数一致，所述第二组连续排列的感应单元122的感应电极和驱动电极的交叉齿数多于所述第一组连续排列的感应单元121的感应电极和驱动电极的交叉齿数，从而令所述第二组连续排列的感应单元122由触摸引起的感应电容的变化量和大于所述第一组连续排列的感应单元121由触摸引起的感应电容的变化量和。
本申请通过增加第二组连续排列的感应单元121的感应电极和驱动电极的交叉齿数，抵消其走线阻抗衰减，提高了第二组连续排列的感应单元121的信噪比。因此，本申请可以在不增加成本的同时，更加有效的检测触摸，提高检测位置的准确度。
具体的，本实施例所述感应单元的感应电极和驱动电极为齿水平交叉，即所述感应电极和驱动电极在水平方向上呈锯齿状交叉，本申请不限于此种方式。参见图5，所述感应单元的感应电极和驱动电极还可以为齿垂直交叉，即所述感应电极和驱动电极在垂直方向上呈锯齿状交叉。参见图6，所述感应单元的感应电极和驱动电极还可以为其它交叉变形形式。
在本申请再一具体实现中，参见图13，本申请实施例还可以采用在所述第二组连续排列的感应单元132中感应电极和驱动电极的宽度和，和/或，面 积和大于所述第一组连续排列的感应单元131宽度和，和/或，面积和的同时，所述第二组连续排列的感应单元132的感应电极和驱动电极的交叉齿数多于所述第一组连续排列的感应单元131的交叉齿数，从而令所述第二组连续排列的感应单元132的触摸变化量大于所述第一组连续排列的感应单元131的触摸变化量。
本申请充分利用了第二组连续排列的感应单元132因走线数量减少，在走线位置附近存在的剩余空间，本申请通过增大所述第二组连续排列的感应单元132中感应电极和驱动电极的宽度和，和/或，面积和，将所述第二组连续排列的感应单元132走线位置附近存在的剩余空间填充为感应单元，使之能够感应触摸，减少了感应盲区，提升了感应准确度。因此，本申请可以在不增加成本的同时，更加有效的检测触摸，提高检测位置的准确度。
同时，本申请还通过增加第二组连续排列的感应单元132的感应电极和驱动电极的交叉齿数，抵消其走线阻抗衰减，提高了第二组连续排列的感应单元132的信噪比。因此，本申请可以在不增加成本的同时，更加有效的检测触摸，提高检测位置的准确度。
本申请还提供一种电容式触摸传感器，包括上述任一种触摸屏感测图案。
本申请所述电容式触摸传感器为Oncell叠构，或者独立电容式触摸屏叠构。
下面通过一具体应用详细说明本申请实现。
参见图14，以Oncell叠构的整合型电容触摸屏为例来说明，包括显示模组下玻璃141、封胶142、显示模组上玻璃143、触摸传感器144、偏光片145、透明光学胶146以及盖板147。其中，触摸传感器144放置于显示模组上玻璃143的上表面。
触摸传感器144包括感应图案，感应图案包括至少一感应单元，感应单元包括感应电极和驱动电极。
参见图15，随着所述感应单元中感应电极与出线端的距离累加所述感应单元中驱动电极与出线端的距离和逐渐增大，所述感应单元中感应电极和驱动电极的宽度和逐渐增大。
本申请充分利用了与出线端的距离远的感应单元附近存在的剩余空间，将与出线端的距离远的感应单元附近存在的剩余空间填充为感应单元，使之 能够感应触摸，减少了感应盲区，提升了感应准确度。因此，本申请可以在不增加成本的同时，更加有效的检测触摸，提高检测位置的准确度。
参见图16，本申请也可以将与出线端的距离近的一组感应单元中感应电极和驱动电极的宽度和不加宽，只将与出线端的距离远另一组感应单元中感应电极和驱动电极的宽度和加宽。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
