Description

触控显示面板 技术领域

随着显示技术的飞速发展，触控显示技术已经逐渐遍及人们的生活中。在现有的触控显示面板中，相对于电阻式触控显示面板，电容式触控显示面板具有寿命长、透光率高、可以支持多点触控等优点，成为触控显示技术的热点。
电容式触控显示面板的触控检测原理为：通过在触控显示面板内形成横纵交叉分布的触控驱动电极和触控感应电极，并在交叉处形成电容矩阵，然后驱动芯片分别向各触控驱动电极施加触控检测信号，并依次检测与各触控驱动电极对应的触控感应电极输出的触控感应信号，从而检测出电容矩阵中的电容变化，判断触控位置。
通常，因触控感应电极在面板中分布的位置不同，触控显示面板中的各触控感应信号线的长度也会不同，进而造成各触控感应信号线的阻抗不同。当上述触控感应电极通过与之电连接的触控信号线输出触控感应信号时，上述阻抗的不同可以导致不同的触控信号线输出触控感应信号时会出现不同时间的延迟情况，进而影响触控显示面板的触控感应灵敏度均一性较差。

 本发明的实施方式

更进一步地，当N=2n（即沿着列方向排布的所述触控感应块111的数量N为偶数）时，P=Q=n；当N=2n+1（即沿着列方向排布的所述触控感应块111的数量N为奇数）时，P=n+1，Q=n，n为正整数。在图1所示优选实施例中，沿着列方向排布的所述触控感应块111的数量N为5，n为2，其对应的所述第一类触控信号线121的数量P为3（所述第一类触控信号线121包括触控信号线C、触控信号线D以及触控信号线E），对应的所述第二类触控信号线122的数量Q为2（所述第二类触控信号线122包括触控信号线A以及触控信号线B）。
具体地，每列所述触控信号线12在行方向（即垂直于所述触控信号线12方向上）具有盲区，所述盲区的盲区宽度为W，一个盲区范围内的所述触控信号线12的数量为t，其中t为正整数且 t≤ N。
具体地，所述触控集成电路21用于提供触控驱动信号及检测触控信号。

由电阻原理可知，所述第二类触控信号线122长度与所述第一类触控信号线121相比偏大，所述第二类触控信号线122对应阻抗R更大。本申请实施例针对触控信号号采用差异化设计方式，在距离触控集成电路远端的触控信号线采用为至少两根子信号线设计方式，在距离触控集成电路近端的触控信号线设置为单根子信号线设计方式，明显降低了距离触控集成电路远端的触控信号线的阻抗，改善触控信号线阻抗带来的触控性能差异问题，提高了触控驱动信号传输的速度，在不改变盲区大小的同时保证了触控性能。
