 本发明的最佳实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有的显示系统，在某些特定画面下数据线会耦合大波纹到触摸屏，对触摸屏造成干扰，致触摸屏失效爆点的技术问题，本实施例能够解决该缺陷。
如图2所示，为本发明提供的调节液晶触摸屏面内干扰的方法的流程图。液晶触摸屏包括显示面板和触摸屏，所述方法包括以下步骤：
步骤S1、采用时序控制器侦测所述显示面板所显示的当前画面，并获取所述当前画面的特征参数；
步骤S2、将所述特征参数与预设特征参数表中的数据进行匹配，若所述特征参数与所述预设特征参数表中的数据一致，则所述时序控制器获取与所述预设特征参数表中的数据对应的调整参数；
步骤S3、根据所述调整参数，对所述显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转，使得相邻两条所述数据线上相对公共电极的耦合电压的变化方向相反。
具体地，在开始所述步骤S1之前，首先应该找到对所述触摸屏产生波纹干扰的所述显示面板的对应的液晶驱动方式，在时序控制器中建立采用该驱动方式所对应的显示画面的特征信息，以建立对所述触摸屏产生波纹干扰的所述显示面板对应画面的参考模型，具体包括以下步骤：
步骤S101、获取对所述触摸屏产生波纹干扰的所述显示面板的预设特征参数；
步骤S102、在所述时序控制器的存储器中建立所述预设特征参数表；
步骤S103、在所述时序控制器的存储器中建立与所述预设特征参数表中的数据对应的调整参数表。已验证知Dot V strip、V Strip by one pixel、V 1+2line、V Strip by sub pixel、H 1+2 line flicker等液晶驱动方式，使显示面板会产生非常大的波纹，从而干扰触摸屏，致所述触摸屏失效爆点。由此，先采集采用上述驱动方式进行液晶驱动时，所述显示面板的预设特征参数；优选的，所述预设特征参数为所述显示面板的数据信号的极性。优选的，所述预设控制器为时序控制器。然后在所述时序控制器的存储器中建立所述预设特征参数表；以及在所述时序控制器的存储器中建立与所述预设特征参数表中的数据对应的调整参数表。该调整参数表可以为所述显示面板的数据信号的极性。其中，因所述预设特征参数（即引起面内干扰的相应画面数据信号极性）在建立上述模型时已经得知，所以根据该预设特征参数便可得知调整参数（即可得知能使得相邻两条数据线上相对公共电极的耦合电压的变化方向相反的数据信号极性），将该调整参数存储至存储器中，需要时调用即可。
建立好产生波纹干扰的参考模型之后，开始对液晶触摸屏面内干扰进行调节。采用所述时序控制器侦测所述显示面板所显示的当前画面，并获取所述当前画面的特征参数。其中，所述特征参数优选为所述显示面板的数据信号的极性。将所述特征参数与所述预设特征参数表中的数据进行匹配，若所述特征参数与所述预设特征参数表中的数据一致，则所述时序控制器获取与所述预设特征参数表中的数据对应的调整参数。根据所述调整参数，对所述显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转，使得相邻两条所述数据线上相对公共电极的耦合电压的变化方向相反。
本实施例仅以DOT V strip为例说明改善效果，当与所述预设特征参数表中数据相匹配的所述当前画面的所述特征参数为“+-+-”极性时，通过所述调整参数调整为“+--+”极性翻转方式显示的画面。
具体请参照图3a所示，所述显示面板包括n条栅极线与m条数据线，其中，n与m为整数；任何一列子像素均连接m条所述数据线中的相邻两条所述数据线，且所述一列子像素间隔的连接于所述两条数据线上；同一行子像素均连接n条所述栅极线中的一条所述栅极线，所述同一行子像素均位于m条所述数据线的同一侧，且相邻两行的所述子像素分别连接于m条所述数据线的两侧；图示以n=4，m=6为例进行说明。
当所述显示面板出现以“+-+-”极性方式进行画面显示时，此时，第m1条数据线上所输入的数据电压的原始极性为正极性，第m2条数据线上所输入的数据电压的原始极性为负极性；其中，m1为奇数，m2为偶数。以第一条数据线D1与第二条数据线D2为例，所述数据线D1以正极性驱动，此时高电平时相对应的子像素为“亮”，所述数据线D1连接的一列子像素从栅极线G1~ G4分别以“亮暗亮暗”分布，即所述数据线D1上的电压由高到低变化；所述数据线D2以负极性驱动，此时低电平时相对应的子像素为“亮”，所述数据线D2连接的一列子像素从栅极线G1~ G4分别以“暗亮暗亮”分布，即所述数据线D2上的电压由高到低变化。所述数据线D1与所述数据线D2相对应的电压变化如图3b~3c所示，在同一时刻，所述数据线D1与所述数据线D2都由高电压变为低电压，两者电压方向变化一致，因此，所述数据线D1与所述数据线D2相对公共电极产生的耦合电压的变化方向一致，所述数据线D1与所述数据线D2之间没有相位差，此时，相邻两条所述数据线上的耦合电压产生相应的叠加，导致公共电极电压干扰严重，所述显示面板会产生非常大的波纹，从而干扰触摸屏。在这种情况下，TP+LCD TX RX波形示意图如图3d所示，可见，所述触摸屏中LCD干扰严重。
此时，若采用本发明所提供的方案，使相应所述数据线上所输入的数据电压的原始极性进行翻转，便会避免发生此现象。具体请参照图4a~4c所示，所述显示面板以上述极性方式进行画面显示时，由Column翻转方式改为1+2line翻转方式，即将上述极性调整为“+--+”极性翻转方式。同样图示以n=4，m=6为例进行说明。以第一条数据线D1与第二条数据线D2为例，所述数据线D1以正极性驱动，连接的一列子像素从栅极线G1~ G4分别以“亮暗亮暗”分布，所述数据线D2以负极性驱动，连接的一列子像素从栅极线G1~ G4分别以“亮暗亮暗”分布。所述数据线D1与所述数据线D2相对应的电压变化如图4b~4c所示，在同一时刻，所述数据线D1上的所述子像素由亮到暗时，对应所述数据线D1的电压变化为由高电压变为低电压；所述数据线D2上的所述子像素由亮到暗时，对应所述数据线D2的电压变化为由低电压变为高电压；数据线D3、D4以此类推，由于相邻两所述数据线之间的电压变化方向相反，使得相邻两所述数据线相对公共电极产生的耦合电压的变化方向相反，所述数据线D1与所述数据线D2之间形成相位差，此时，相邻两条所述数据线上的耦合电压发生相互抵消，从而减轻公共电极电压受到的干扰，从而从源头消除波纹的干扰，使触摸屏在该特定画面下能正常工作。改善后TP+LCD TX RX波形示意图如图4d所示，可见很好的解决了所述触摸屏中LCD干扰问题。
本发明还提供一种调节液晶触摸屏面内干扰的装置，液晶触摸屏包括显示面板和触摸屏，如图5所示，所述装置50包括：侦测模块51、匹配模块52、获取模块53、翻转模块54。

所述侦测模块51，用于实时侦测所述显示面板所显示的当前画面，并用于获取所述当前画面的特征参数；所述特征参数优选为所述显示面板的数据信号的极性参数。其中，所述侦测模块51包括：第一子侦测模块，用于侦测对所述触摸屏产生波纹干扰的所述显示面板的预设特征参数，以便建立上述模型；第二子侦测模块，用于侦测所述显示面板当前画面的所述特征参数。

所述获取模块53，根据所述匹配模块52的匹配信息，若所述特征参数与所述预设特征参数表中的数据一致，则用于获取与所述预设特征参数表中的数据对应的所述调整参数。
所述翻转模块54，用于接收所述调整参数，并用于对所述显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转，使得相邻两条所述数据线上相对公共电极的耦合电压的变化方向相反。

本发明还提供一种显示系统，包括液晶触摸屏和上述调节所述液晶触摸屏面内干扰的所述装置；该装置与所述液晶触摸屏连接，以对所述液晶触摸屏面内干扰进行调节。

综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
