如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
第一实施例
请参阅图1，本发明第一实施例的触控显示面板100为内嵌式触控显示面板，其包括TFT基板10、与TFT基板10相对设置的彩色滤光片基板60、位于TFT基板10与彩色滤光片基板60之间的液晶层80以及设置于TFT基板10与彩色滤光片基板60之间用于支撑该液晶层80间隙的多个间隔体(图未示)。
该TFT基板10包括基板111和设置于基板111朝向彩色滤光片基板60的表面的导电材料层110。所述导电材料层110至少形成公共电极。可以理解，该TFT基板10还包括形成于基板111上的中间层112，该中间层112位于该基板111与该导电材料层110之间，该中间层112可为多层结构，其可形成为薄膜晶体管阵列、绝缘覆盖层、像素电极、扫描线以及数据线等TFT基板的常规元件。
基板111用于承载TFT基板10的各元件，基板111可以为透明基板，例如由玻璃、透明塑料等形成的基板。
该导电材料层110可作为显示用的公共电极，同时作为感测触控的触控电极层用来检测是否存在触控操作以及触控位置。
可以理解的，所述触控显示面板100定义有显示区和非显示区，进而所述TFT基板10也定义有显示区101和非显示区102(如图2所示)，所述非显示区102围绕所述显示区101。该导电材料层110形成间隔设置的多个触控感应电极12、间隔设置的多个触控驱动电极13、以及间隔设置的多个公共电极15；其中，所述多个触控驱动电极13、多个触控感应电极12和多个公共电极15均设置在该显示区101。该导电材料层110采用本领域常规使用的各种透明导电材料。
请参阅图2，每一个触控感应电极12大致呈矩形块状；所述多个触控感应电极12沿第一方向(图2中D1方向)排布成多行，沿第二方向(图2中D2方向)排布成多列。该第一方向与第二方向交叉。本实施例中，该第一方向与第二方向垂直。图2仅示意性呈现每一行触控感应电极12包括有六个触控感应电极12；实际上，一行触控感应电极12的数量不限于六个，也可设置六个以上。每一个触控驱动电极13沿第一方向延伸成长条状，每一个公共电极15沿第一方向延伸成长条状，所述多个触控驱动电极13和所述多个公共电极15沿第二方向间隔排布成一列。本实施例中，每一个触控驱动电极13与每一个公共电极15在第一方向的长度大致相同，且二者在第二方向两端对齐设置；另外，二者与每一行触控感应电极12也是第一方向对齐设置。本实施例中，每一个触控感应电极12沿第一方向的长度可设置为3-6mm。本实施例中，每一个触控驱动电极13在第二方向的宽度大于每一个公共电极15在第二方向的宽度。
如图2所示，沿第二方向每一个触控驱动电极13的两侧的每一侧均设置有一个公共电极15以及一行触控感应电极12；其中，每一个触控驱动电极13位于相邻的两个公共电极15之间，每一个公共电极15位于相邻的一个触控驱动电极13与一行触控感应电极12之间。在所述显示区101中，每一个触控驱动电极13及其两侧与其相邻的两个公共电极15和两行触控感应电极12构成一个基本单元103(如图2所示)，所述导电材料层110包括多个基板单元103，沿第二方向所述多个基本单元103周期性重复排列。
请进一步参阅图2，该TFT基板10还包括多条感测线113。所述感测线113由不同于所述导电材料层110的其他导电层形成。可以理解的，对应在该导电材料层110与该感测线113所在的导电层之间设置有一绝缘材料层(图未示)。本实施例中多条感测线113形成在导电材料层110朝向彩色滤光片基板60一侧。每一条感测线113连接同一列的触控感应电极12中相邻的两个触控感应电极12，且每一条感测线113与所述触控驱动电极13和所述公共电极15电性绝缘。同一列触控感应电极12中，每相邻的两个触控感应电极12通过至少一条感测线113电性连接。每一条感测线113通过贯穿绝缘材料层的过孔18连接相应的触控感应电极12。每一条感测线113沿第二方向延伸。同一列的触控感应电极12中通过多条感测线113电性连接，不同列的触控感应电极12相互绝缘。连接位于每一个触控驱动电极13两侧的两个触控感应电极12的感测线113跨越了一个触控驱动电极13及该触控驱动电极13两侧的两个公共电极15。
本实施例中，同一列中每相邻的两个触控感应电极12通过四条平行设置的感测线113电性连接，且所述四条平行设置的感测线113沿第一方向间隔排布。
如图2所示，所述多个触控驱动电极13、所述多个触控感应电极12、所述多个公共电极15以及所述多条感测线113定义形成多个触控感测单元20。所述多个触控感测单元20成矩阵排列成多行多列。每行(沿第一方向)触控感测单元20构成上述的一个基本单元103。每一个触控感测单元20包括位于同一列(第二方向)中的两个触控感应电极12、位于所述两个触控感应电极12之间的一个触控驱动电极13的部分、位于所述两个触控感应电极12之间的两个公共电极15的部分、以及连接于所述两个触控感应电极12之间的感测线113。
所述导电材料层110还包括设置在非显示区102的两个连接电极14。所述两个连接电极14分别设置在该显示区101沿第一方向的两侧(左右侧)。每一个连接电极14沿第二方向延伸成长条状。
所述触控显示面板100的非显示区102还设置有至少一驱动控制器30。本实施例中，所述驱动控制器30的数量为两个。本实施例中，每一个驱动控制器30位于连接电极14远离所述显示区101的一侧；每一个连接电极14位于驱动控制器30与所述显示区101之间。驱动控制器30用以发送触控驱动信号。
该连接电极14与每一个公共电极15分别通过一导线115电性连通。每一个公共电极15沿第一方向的两端分别电性连接一连接电极14，如此使所述多个公共电极15并联设置，降低整体的电阻。每一个触控驱动电极13分别通过一导线114直接电性连接驱动控制器30。
所述触控驱动电极13和所述触控感应电极12复用为公共电极。所述触控显示面板100采用分时驱动法。在显示时段，显示驱动信号(如公共电极电压)被施加给触控驱动电极13、所述触控感应电极12、和公共电极15；在触控感测时段，所述驱动控制器30发出触控驱动信号给触控驱动电极13。所述触控驱动信号可为正弦波、方波或三角波。
所述触控显示面板100的非显示区102还设置有一读取电路50。所述读取电路50设置在该显示区101沿第二方向的一侧，本实施例为该显示区101的下侧。同一列的触控感应电极12中通过多条感测线113电性连接，且每一列触控感应电极12靠近所述读取电路50的感测线113电性连接所述读取电路50，使每一列触控感应电极12与所述读取电路50电性连接。所述读取电路50用以接收所述触控感应电极12的触摸感应信号。
在每一个触控感测单元20中，触控驱动电极13与该触控感测单元20中的两个触控感应电极12分别形成一第一电容；触控驱动电极13和沿第二方向与其相邻的一触控感测单元20的触控感应电极12形成第二电容；同时触控驱动电极13与该触控感测单元20中的感测线113形成寄生电容。
每一个触控感测单元20的电容C可通过下面的公式计算：
C＝2×C1+N×C2+M×C3+Cother
其中，C1为第一电容的电容，C2为第二电容的电容，C3为寄生电容的电容，M为该触控感测单元20中的感测线113的数量，N的数值为1或2，Cother为触控驱动电极13与其他导电层形成的电容。参上所述，由于在每一个触控感测单元20中，触控驱动电极13与两个触控感应电极12分别形成第一电容，因此在每一个触控感测单元20中具有两个第一电容的电容C1。当一触控感测单元20位于图2所示第二方向排列的第一行(沿第一方向)的触控感测单元20中或最后一行(沿第一方向)的触控感测单元20中，则沿第二方向与该触控感测单元20相邻的仅有一个触控感测单元20，则此时N等于1；其他情况的触控感测单元20沿第二方向与该触控感测单元20相邻的有两个触控感测单元20，则此时N等于2。
第二实施例
请参阅图3所示的第二实施例的TFT基板200，该TFT基板200与第一实施例的TFT基板10基本相同，包括同样排布的导电材料层110(包括同样排布的多个触控驱动电极13、多个触控感应电极12、以及多个公共电极15)、连接电极14、驱动控制器30、和读取电路50。该TFT基板200与第一实施例的TFT基板10的区别在于：感测线113的排布连接方式有所不同；第一实施例中，同一列触控感应电极12中每相邻的两个触控感应电极12通过感测线113电性连接，且每一列触控感应电极12与所述读取电路50通过感测线113电性连接；而本实施例中，每一个触控感测单元20中的两个触控感应电极12通过感测线113电性连接，不同触控感测单元20的触控感应电极12相互不连接，且每一个触控感测单元20与所述读取电路50通过感测线113电性连接。
如图3所示，本实施例中，同一个触控感测单元20中的两个触控感应电极12通过至少一条感测线113电性连接，所述至少一条感测线113沿第一方向间隔排布，且其中一条感测线113延伸直接电性连接所述读取电路50。
第三实施例
请参阅图4所示的第三实施例的TFT基板300，该TFT基板300与第一实施例的TFT基板21基本相同，包括同样排布的导电材料层110(包括同样排布的多个触控驱动电极13、多个触控感应电极12、以及多个公共电极15)、连接电极14、驱动控制器30、和读取电路50。该TFT基板200与第一实施例的TFT基板21的区别在于：该TFT基板300中还进一步设置有虚拟单元70。本实施例中，虚拟单元70设置在非显示区102，数量为两个，所述两个虚拟单元70对称设置在所述多个触控感测单元20沿第二方向的两侧(上下侧)。
如图4所示，每一个虚拟单元70包括一虚拟触控驱动电极71、一虚拟公共电极72和一虚拟触控感应电极73的行(沿第一方向)，其中虚拟公共电极72位于虚拟触控驱动电极71和虚拟触控感应电极73的行(沿第一方向)之间，虚拟触控感应电极73的行(沿第一方向)位于虚拟公共电极72与触控感应电极12的行之间。所述虚拟触控驱动电极71和虚拟公共电极72不连接所述驱动控制器30。所述虚拟触控感应电极73与其沿第二方向相邻的触控感应电极12通过感测线电性连接。如此设置虚拟单元70，可补偿显示区101上下边缘处的电容，使整个显示区101的感应电容均匀分布。所述虚拟单元70也可由导电材料层110形成。
请参阅图5所示触控驱动电极13的驱动时序图，该驱动时序图适用于上述三个实施例。所述触控显示面板100采用分时驱动法；在显示时段T1，触控驱动电极13被施加一直流电压(公共电极电压)；在触控感测时段T2，触控驱动电极13被施加触控驱动信号(脉冲信号电压)。
上述实施例的TFT基板通过将触控驱动电极13、多个触控感应电极12、以及多个公共电极15通过同一导电材料层形成，有效降低了TFT基板的厚度。
以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换，而不脱离本发明技术方案的精神和范围。
