具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1及图2，本发明较佳实施方式提供一种触摸传感器100。所述触摸传感器100应用于显示装置(未示出)中。所述触摸传感器100包括N个平行设置的第一触摸电极串列Tx1-Txn及N个平行设置的第二触摸电极串列Rx1-Rxn。其中，所述第二触摸电极串列Rx1-Rxn与所述第一触摸电极串列Tx1-Txn绝缘。
每一第一触摸电极串列包括相同数量的第一触摸电极11。所述第一触摸电极11沿第一方向I1排布。所述第一触摸电极串列中的相邻两第一触摸电极11通过第一导电桥12或第二导电桥13连接。其中，所述第一导电桥12与所述第二导电桥13的电阻不同，以调节N个第一触摸电极串列Tx1-Txn的互电容，从而使得N个第一触摸电极串列Tx1-Txn的互电容相同或之间的差值在第一预设范围内。
请继续参阅图2，每一第二触摸电极串列包括相同数量的N个第二触摸电极21。所述第二触摸电极21沿着第二方向I2排布，其中，所述第二方向I2与所述第一方向I1交叉。所述第二触摸电极串列中的相邻两第二触摸电极21通过第三导电桥22或第四导桥23连接。所述第三导电桥22与所述第四导电桥23的电阻不同，以调节N个第二触摸电极串列Rx1-Rxn的互电容，从而使得N个第二触摸电极串列Rx1-Rxn的互电容相同或之间的差值在第二预设范围内。
需要说明的是，在每个第一触摸电极串列中，相邻的两个第一触摸电极11之间不是通过所述第一导电桥12连接就是通过所述第二导电桥13连接。且每个第一触摸电极串列连接的第一导电桥12及第二导电桥13的总数量相同。同理，在每个第二触摸电极串列中，相邻的两个第二触摸电极21之间不是通过所述第三导电桥22连接就是通过所述第四导电桥23连接。且每个第二触摸电极串列20连接的第三导电桥22及第四导电桥23的总数量相同。在本实施方式中，所述第一方向I1垂直于所述第二方向I2。其中，图1显示的是N个第一触摸电极串列Tx1-Txn所在的层的平面图。图2显示的是N个第二触摸电极串列Rx1-Rxn所述在的层的平面图。
具体地，第一导电桥12与所述第三导电桥22的材质相同，所述第二导电桥13及所述第四导电桥23的材质相同。所述第一及第三导电桥12及22的材 质为金属。所述第二及第四导电桥13及23的材质为氧化铟锡。所述第一预设范围与所述第二预设范围相同。在其他实施方式中，所述第一导电桥12与所述第三导电桥22的材质可以不同。所述第二导电桥13及所述第四导电桥23的材质也可以不同。所述第一预设范围与所述第二预设范围可以不同，并可以根据实际需要确定。
在本实施方式中，所述触摸传感器100包括N个平行设置的第一触摸电极串列Tx1-Txn及N个平行设置的第二触摸电极串列Rx1-Rxn，其中，所述第二触摸电极串列Rx1-Rxn与所述第一触摸电极串列Tx1-Txn绝缘。每一第一触摸电极串列包括相同数量的第一触摸电极11。所述第一触摸电极11沿第一方向I1排布。所述第一触摸电极串列10中的相邻两第一触摸电极11通过第一导电桥12或第二导电桥13连接。其中，所述第一导电桥12与所述第二导电桥13的电阻不同，以调节N个第一触摸电极串列Tx1-Txn的互电容，从而使得N个第一触摸电极串列Tx1-Txn的互电容相同或之间的差值在第一预设范围内。每一第二触摸电极串列包括相同数量的第二触摸电极21。所述第二触摸电极21沿着第二方向I2排布，其中，所述第二方向I2与所述第一方向I1交叉。所述第二触摸电极串列Rx1-Rxn中的相邻两第二触摸电极21通过第三导电桥22或第四导桥23连接。所述第三导电桥22与所述第四导电桥23的电阻不同，以调节N个第二触摸电极串列Rx1-Rxn的互电容，从而使得N个第二触摸电极串列20的互电容相同或之间的差值在第二预设范围内。因此，所述触摸传感器100的第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn的互电容相同或之间的差值分别在第一及第二预设范围内，从而使得所述触摸传感器100的互电容达到均衡，进而提高了所述触摸传感器100的触控能力。
具体地，所述触摸传感器100还包括焊盘组30、第一组敷设线40及第二组敷设线50。所述焊盘组30、所述第一组敷设线40及所述第二敷设线焊盘50均设置于由所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn形成的区域的外部。所述第一组敷设线40对应N个第一触摸电极串列Tx1-Txn。每一第一触摸电极串列通过第一组敷设线40中相应的敷设线连接至所述焊盘组30中相应的焊盘。所述第二组敷设线50对应N个第二触摸电极串列Rx1-Rxn。每一第二触摸电极串列通过第二组敷设线50中相应的敷设线连接至所述焊盘 组30中相应的焊盘。当所述第一导电桥12的电阻小于所述第二导电桥13的导电性能时，在N个第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中连接的第一导电桥12的数量与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比。
具体地，所述第一组敷设线40中的敷设线的第一端连接至相应的第一触摸电极串列，该敷设线的第二端连接至相应的焊盘。由于第一触摸电极串列距离所述焊盘组30的距离不同，则相应的敷设线的布设长度也不同。其中，所述敷设线的长度越长，其电阻越大。当所述第一导电桥12的电阻小于所述第二导电桥13的导电性能时，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中连接的第一导电桥12的数量与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比。即为连接敷设线长的第一触摸电极串列中连接的第一导电桥12的数量相较于连接敷设线较短的第一触摸电极串列中连接的第一导电桥12的数量少，故连接敷设线长的第一触摸电极串列中的电阻相较于连接敷设线较短的第一触摸电极串列的电阻小。连接敷设线长的第二触摸电极串列中连接的第三导电桥22的数量相较于连接敷设线较短的第二触摸电极串列中连接的第三导电桥12的数量少，故连接敷设线长的第二触摸电极串列中的电阻相较于连接敷设线较短的第二触摸电极串列的电阻小。因此，将外围敷设线和相应的第一及第二触摸电极串列作为整体来看，所述第一及第二触摸电极串列可以达到电阻性均衡，从而所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn可以达到互电容均衡，进而提高了所述触摸传感器100的触控性能。
请参阅图3及图4，现在举一实例来说明所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn达到互电容均衡的状况。假设触摸感应器包括三个第一触摸电极串列TX1、TX2、TX3及四个第二触摸电极串列RX1、RX2、RX3、RX4。连接在第一触摸电极串列TX3与相应的焊盘之间的敷设线L13的长度大于连接在第一触摸电极串列TX2与相应的焊盘之间的敷设线L12的长度，连接在第一触摸电极串列TX2与相应的焊盘之间的敷设线L12的长度大于连接在第一触摸电极串列TX1与相应的焊盘之间的敷设线L11的长度。连接在第二触 摸电极串列RX1与相应的焊盘之间的敷设线L21的长度等于连接在第二触摸电极串列RX4与相应的焊盘之间的敷设线L24的长度，且大于连接在第二触摸电极串列RX2与相应的焊盘之间的敷设线L22的长度。连接在第二触摸电极串列RX2与相应的焊盘之间的敷设线L22的长度与连接在第二触摸电极串列RX3与相应的焊盘之间的敷设线L23的长度。因此，所述第一触摸电极串列TX3上连接有四个第一导电桥12。所述第一触摸电极串列TX2上连接两个第一导电桥12及两个第二导电桥13。所述第一触摸电极串列TX1包括一个第一导电桥12及三个第二导电桥13。所述第二触摸电极串列RX1包括三个第三导电桥22。所述第二触摸电极串列RX2上连接两个第三导电桥22及一个第四导电桥23。所述第三触摸电极串列RX3上连接两个第三导电桥22及一个第四导电桥23。所述第四触摸电极串列RX4上连接三个第三导电桥22。从而实现了第一触摸电极串列TX1、TX2及TX3达到了互电容的均衡，及第二触摸电极串列RX1、RX2、RX3及RX4的互电容达到了均衡，进而提高了所述触摸传感器的触控性能。
请继续参阅图5及图6，本发明第二较佳实施方式提供一种触摸传感器200。所述第二较佳实施方式提供的触摸传感器200与第一较佳实施方式提供的触摸传感器100相似，两者的区别在于：在第二较佳实施方式中，所述触摸传感器200好包括第一导电介质210及第二导电介质220。所述第一导电介质210布设于所述第一触摸电极串列的第一触摸电极11内，以调节N个第一触摸电极串列Tx1-Txn的互电容，从而使得N个第一触摸电极串列Tx1-Txn的互电容相同或差值在第一预设范围内。所述第二导电介质220布设于所述第二触摸电极串列Rx1-Rxn的第二触摸电极21内，以调节N个第二触摸电极串列Rx1-Rxn的互电容，从而使得N个第二触摸电极串列Rx1-Rxn的互电容相同或差值在第二预设范围内。
具体地，在N个第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的第一及第二导电介质210及220的数量与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比。
需要说明的是，所述第一及第二导电介质210及220布设于所述第一及第 二触摸电极串列Tx1-Txn及Rx1-Rxn会减小所述第一及第二触摸电极串列的电阻。且在第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn布设的第一及第二导电介质210及220的数量越多，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn的阻值减小的程度越大。因此，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的第一及第二导电介质210及220的数量与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比，可以使得所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn的互电容均衡，从而提高所述触摸传感器200的触摸性能。
在本实施方式中，所述第一及第二导电介质210及220为金属丝。在N个第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的金属丝总长度与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比。
需要说明的是，在所述第一触摸电极串列，可以所有的第一触摸电极11布设有所述金属丝，也可以只有部分第一触摸电极11布设金属丝。同理，在所述第二触摸电极串列，可以所有的第二触摸电极21布设所述金属丝，也可以只有部分第二触摸电极21布设金属丝。所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的金属丝总长度即为，所述第一触摸电极串列中的所有的金属丝的长度之和。在第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的金属丝总长度越长，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn的阻值减小的程度越大。因此，所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn中布设的金属丝总长度与所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn连接的相应的敷设线的长度呈正比，可以使得所述第一及第二触摸电极串列Tx1-Txn及Rx1-Rxn的互电容均衡，从而提高所述触摸传感器200的触摸性能。
进一步地，所述触摸传感器200还包括上基板(未示出)。所述N个第一触摸电极串列Tx1-Txn及N个第二触摸电极串列Rx1-Rxn形成在所述上基板上。
请继续参阅图7，本发明第二方案较佳实施方式提供一种显示装置300。所述显示装置300包括显示面板310、密封剂320及触摸传感器。所述触摸传 感器可以为上述第一方案第一较佳实施方式提供的触摸传感器100。
需要说明的是，所述触摸传感器也可以为上述第一方案第二较佳实施方式提供的触摸传感器200。由于所述触摸传感器100及200均已在上述第一方案的第一及第二较佳实施方式进行了具体的描述，故在此不再进行赘述。
在本实施方式中，所述触摸传感器100包括N个平行设置的第一触摸电极串列10及N个平行设置的第二触摸电极串列20，其中，所述第二触摸电极串列20与所述第一触摸电极串列10绝缘。每一第一触摸电极串列10包括相同数量的N个第一触摸电极11。所述第一触摸电极11沿第一方向排布。所述第一触摸电极串列10中的相邻两第一触摸电极11通过第一导电桥12或第二导电桥13连接。其中，所述第一导电桥12与所述第二导电桥13的电阻不同，以调节N个第一触摸电极串列10的互电容，从而使得N个第一触摸电极串列10的互电容相同或之间的差值在第一预设范围内。每一第二触摸电极串列20包括相同数量的N个第二触摸电极21。所述第二触摸电极21沿着第二方向排布，其中，所述第二方向与所述第一方向交叉。所述第二触摸电极串列20中的相邻两第二触摸电极21通过第三导电桥22或第四导桥23连接。所述第三导电桥22与所述第四导电桥23的电阻不同，以调节N个第二触摸电极串列20的互电容，从而使得N个第二触摸电极串列20的互电容相同或之间的差值在第二预设范围内。因此，所述触摸传感器100的第一及第二触摸电极串列10及20的互电容相同或之间的差值分别在第一及第二预设范围内，从而使得所述触摸传感器100的互电容达到均衡，进而提高了所述触摸传感器100的触控能力。
