具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，在相关技术中的触控显示模组中，上面一行像素单元为第n行像素单元，下面一行像素单元为第n+1行像素单元，n为正整数；Data1、Data2、Data3、Data4、Data5、Data6分别标示第一数据线、第二数据线、第三数据线、第四数据线、第五数据线、第六数据线，Gatan标示第n栅线，Gaten+1标示第n+1栅线；第一列像素单元与Data1连接，第二列像素单元与Data2连接，第三列像素单元与Data3连接，第四列像素单元与Data4连接，第五列像素单元与Data5连接，第六列像素单元与Data6连接，第n行像素单元与Gaten连接，第n+1行像素单元与Gaten+1连接。
由图1可知，相关技术中的触控显示模组采用单像素补偿电路，针对每一列像素单元需要设置一条数据线以在显示时间段提供数据信号，并且需要额外在像素区域设置过孔及触控扫描线以在触控时间段为触控电极提供触控扫描信号，这部分设计会占用像素区的开口率，进而影响显示面板的使用寿命。
为了解决上述技术问题，本公开实施例提供一种触控显示模组。
本公开实施例所述的触控显示模组，包括触控电极、呈多行多列排列的像素单元以及横纵交叉的多条栅线和多条数据线。所述触控显示模组还包括多条触控扫描线。
每两相邻数据线之间设置有两列像素单元，每条数据线和与其紧邻的两列像素单元电连接。
两相邻数据线之间设置有所述触控扫描线，所述触控扫描线与所述触控电极连接。
每相邻两行像素单元之间设置有两条栅线。
一行像素单元包括相邻的第一像素单元和第二像素单元，所述栅线包括第一栅线和第二栅线；第一像素单元和第二像素单元与同一条数据线电连接；所述第一像素单元与第一栅线连接，所述第二像素单元与第二栅线连接。
在本公开实施例所述的触控显示模组中，第一像素单元和第二像素单元位于同一行相临列，第一像素单元和第二像素单元与不同的栅线连接。
本公开实施例所述的触控显示模组通过在每相邻两条数据线之间设置两 列像素单元，并使得每条数据线和与其紧邻的两列像素单元电连接，同时通过设置于两相邻数据线之间的触控扫描线为触控电极提供触控扫描信号，从而在减少数据线数目的同时不需在像素区域设置触控扫描线，从而提高像素区域的开口率，增加显示面板的寿命。
具体的，所述触控扫描线设置于相邻的两列像素单元之间，该相邻的两列像素单元与不同的数据线连接，也即触控扫描线位于相邻的与不同的数据线连接的两列像素单元之间。所述触控扫描线的具体位置在之后的具体实施例中将结合附图详细介绍。
可选的，所述触控扫描线与所述数据线同向设置，即可以是本公开实施例所述的触控显示模组在每相邻两条数据线之间设置两列像素单元，并使得每条数据线和与其紧邻的两列像素单元电连接将节省下来的信号线用作触控扫描线，从而简化触控扫描布线的程序并提高开口率。
具体的，本公开所述的触控显示模组还包括触控驱动单元。
所述触控驱动单元，与所述触控扫描线连接，用于在触控时间段通过所述触控扫描线向所述触控电极输出触控扫描信号。
在实际操作时，每一显示周期包括显示时间段和触控时间段；本公开实施例所述的触控显示模组包括的触控驱动单元在触控时间段通过设置于两相邻数据线之间的触控扫描线向触控电极输出触控扫描信号。
如图2所示，在本公开所述的触控显示模组的一具体实施例中，上面一行像素单元为第n行像素单元，下面一行像素单元为第n+1行像素单元，n为正整数；
Data1、Data2、Data3分别标示第一数据线、第二数据线、第三数据线，TPM1、TPM2、TPM3分别标示第一触控扫描线、第二触控扫描线、第三触控扫描线；
第一列像素单元与Data1连接；第二列像素单元和第三列像素单元都与Data2连接；第四列像素单元和第五列像素单元都与Data3连接；
TPM1设置于Data1和Data2之间，TPM2设置于Data2和Data3之间，TPM3设置于Data3和第四数据线(图2中未示出)之间；
在显示时间段，通过Data1、Data2、Data3分别为其所连接的像素单元提 供数据信号；在触控时间段，通过TPM1、TPM2和TPM3为其分别连接的触控电极提供触控扫描信号；
在图2中，Gate2n-1标示第2n-1栅线，Gata2n标示第2n栅线；
Gate2n-1和Gate2n设置于第n行像素单元和第n+1行像素单元之间；
并且，第n行第一列像素单元与Gate2n连接，第n行第2列像素单元与Gate2n-1连接，第n行第3列像素单元与Gate2n连接，第n行第4列像素单元与Gate2n-1连接，第n行第5列像素单元与Gate2n连接，第n行第6列像素单元与Gate2n-1连接，Gate2n、Gate2n-1在显示时间段控制第n行第2列像素单元、第n行第3列像素单元分时接入Data2上的数据信号，Gate2n、Gate2n-1在显示时间段控制第n行第4列像素单元、第n行第5列像素单元分时接入Data3上的数据信号。
在相关技术中的触控显示模组中，并未采用一根数据线为两列像素单元提供数据信号，从而需要比图2中多一倍的数据线，也即图2中的触控扫描线所在的位置在相关技术中设置的为数据线，在数据线多的情况下还需另设触控扫描线，从而导致开口率过低。而本公开如图2所示的触控显示模组的具体实施例采用双像素补偿电路(即通过一数据线为两列像素单元提供数据信号)的排布方式，这样在两条数据线之间就可以设置一条触控扫描线，可以提高开口率。
可选的，本公开实施例所述的触控显示模组还包括多个阴极电极。
所述多个阴极电极被复用为触控电极。
所述触控驱动单元具体用于在触控时间段通过所述触控扫描线向所述阴极电极输出触控扫描信号。
在内嵌自容式AMOLED触控显示模组结构设计时，通常是每一所述阴极电极对应设置于多个像素单元上方，通过对处于最上方的阴极电极分割复用的方式，将原本是整层的阴极电极对应于每个像素区域分割为多个块状的阴极电极，每一个块状的阴极电极在触控时间段作为一个触控电极，在触控时间段通过触控扫描线向所述多个块状的阴极电极发送触控扫描信号。
在相关技术中，当将多个阴极电极分割复用为触控电极时，需要通过下方金属连接的方式，在像素区域设计过孔及设计TPM(触控电极)走线，这 部分设计会占用像素区的开口率，进而影响OLED的使用寿命。
具体的，每一所述像素单元包括相互连接的OLED(Organic Light-Emitting Diode，有机发光二极管)和像素驱动电路。
在一实施例中，所述像素驱动电路用于在触控时间段控制相应的OLED的阳极处于浮空状态，从而控制OLED不发光，使得阴极和阳极之间的电容可以忽略不计，大大降低RC loading(负载)，有利于提高触控驱动频率。
具体的，所述像素驱动电路与发光控制线连接。
所述触控驱动单元，还与所述发光控制线连接，还用于在触控时间段向所述发光控制线输出发光关闭控制信号，以使得所述像素驱动电路控制相应的OLED的阳极处于浮空状态，通过这种插黑的方式(即阳极不通电的方式)，使得在触控时间段OLED的阳极相当于浮空状态。
可选的，所述触控驱动单元还用于在触控时间段向与所述像素驱动电路连接的除了所述发光控制线之外的控制线和与所述像素驱动电路连接的信号线输出所述触控扫描信号。
在本公开所述的触控显示模组的可选实施例中，在触控时间段，不仅向触控电极输出触控扫描信号，也同时向位于所述触控电极下方的与自容式AMOLED触控显示模组包括的像素驱动电路连接的控制线和与所述像素驱动电路连接的信号线(除了发光控制线之外)也输出所述触控扫描信号，也即在触控时间段同步驱动触控电极、与所述像素驱动电路连接的控制线和与所述像素驱动电路连接的信号线(除了发光控制线之外)，目的是抵消对地电容对触控电极的影响。

在图5所示的驱动电路的具体实施例中，所有的晶体管都为p型TFT。
如图5所示的驱动电路的具体实施例在工作时，工作时序图如图6所示，在图6中，S1标示每一显示时间段的重置阶段，S21标示每一显示时间段的第一充电阶段，S3标示每一显示时间段的第二充电阶段，S4标示每一显示时间段的发光阶段，S5标示触控时间段。
如图5所示的驱动电路在工作时(在图7A、图7B、图7C和图7D中，用虚线框起来的TFT表示该TFT在相应阶段断开)，
如图7A所示，在每一显示时间段的重置阶段S1，T11和T21导通，T12、T13、T14、T15、T22、T23、T24和T25断开，此时a1和a2重置接地；
如图7B所示，在每一显示时间段的第一充电阶段S2，T12、T13导通，T22、T23、T11、T14、T15、T21、T24和T25断开，由于之前a1和a2接地， 所以驱动DTFT1打开，Datan上的第一数据电压Vdata1依次通过T12、DTFT1和T13开始对a1进行充电，一直将a1的电位充电到Vdata1-Vth1为止(满足DTFT1的栅源两极之间的压差为DTFT1的阈值电压Vth1)，该过程中，由于b1始终接入VDD，所以当充电完毕后，b1的电位会一直维持在Vdata1-Vth1，另外由于T15的关闭使得电流不会通过OLED1，间接降低了OLED1的寿命损耗；
如图7C所示，在每一显示时间段的第二充电阶段S3，T22和T23导通，T12、T13、T11、T14、T15、T21、T24和T25断开，由于之前a1和a2接地，所以驱动DTFT2打开，Datan上的第二数据电压Vdata2依次通过T22、DTFT2和T23开始对a2进行充电，一直将a2的电位充电到Vdata2-Vth2为止(满足DTFT2的栅源两极之间的压差为DTFT2的阈值电压Vth2)，该过程中，由于b2始终接入VDD，所以当充电完毕后，b2的电位会一直维持在Vdata2-Vth2，另外由于T25的关闭使得电流不会通过OLED2，间接降低了OLED2的寿命损耗；
如图7D所示，在每一显示时间段的发光阶段S4，即AMOLED像素正式发光阶段，此时DTFT1的源极和DTFT2的源极都接入VDD，电流依次经过T14、DTFT1和T15使得OLED1开始发光，电流依次T24、DTFT2和T25使得OLED2开始发光；
由TFT饱和电流公式可以得到：
IOLED1＝K1×(VGS1-Vth1)2＝K1×[VDD-(Vdata1-Vth1)-Vth1]2＝K1×(VDD-Vdata1)2；
IOLED2＝K2×(VGS2-Vth2)2＝K2×[VDD-(Vdata2-Vth2)-Vth2]2＝K2×(VDD-Vdata2)2；
其中，K1为DTFT1的电流放大系数，VGS1为DTFT1的栅源电压，IOLED1为OLED1的工作电流，K2为DTFT2的电流放大系数，VGS2为DTFT2的栅源电压，IOLED2为OLED2的工作电流。
由上式可以看到此时IOLED1已经不受Vth1的影响，只与VDD和Vdata1有关，IOLED2已经不受Vth2的影响，只与VDD和Vdata2有关，彻底解决了驱动晶体管由于工艺制程及长时间的操作造成阈值电压漂移的问题，消除其 对流过有机发光二极管的电流的影响，保证OLED1和OLED2的正常工作。
在触控时间段S5，可以看到，除了阴极电极(触控电极)开始驱动以外，除了发光控制线EM之外的其他的信号线(输出高电平VDD的高电平线、输出数据电压Vdata的数据线、第一扫描线Scan1、第二扫描线Scan2)都同步进行驱动，并且触控驱动信号的幅值相对于上述信号线在显示时间段的电压幅值比较小，因此可以保证所有的TFT(Thin Film Transistor，薄膜晶体管)都保持原来的开关状态(即保持在显示时间段的发光阶段的状态)。由于此时OLED1的阳极和OLED2的阳极无电压通过，因此处于浮空状态，此时无需计算触控电极与阳极间的电容，降低RC loading(负载)，可以有效提高驱动频率。
