本发明的至少一个实施例涉及一种内嵌式触控显示面板、其驱动方法及显示装置。
背景技术
触控显示面板已广泛用于电视机、手机、便携终端及其它显示装置中。将触控电极内嵌于显示屏内部的嵌入式(In-cell)触控显示面板，既可以减薄模组整体的厚度，又可以降低触控显示面板的制作成本，受到各大厂商的重视。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。
图1示出了一种内嵌式触控显示面板的平面示意图；
图2示出了沿图1中的线A-A的截面图；
图3示出了根据本发明实施例的内嵌式触控显示面板的平面示意图；
图4示出了沿图3中的线B-B的截面图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请的发明人注意到，在图1和图2所示的内嵌式触控显示面板中，触控驱动电极与触控感应电极之间的互容较小，触控灵敏度不高。
图3示出了根据本发明实施例的内嵌式触控显示面板的平面示意图；图4示出了沿图3中的线B-B的截面图。如图4所示，根据本发明的至少一个实施例的内嵌式触控显示面板包括阵列基板10，阵列基板10包括公共电极层11，公共电极层11包括多个第一触控驱动电极12a和多个第二触控驱动电极12b，第一触控驱动电极12a与第二触控驱动电极12b交叉绝缘设置，且第二触控驱动电极12b包括多个并排设置的第二触控子电极121。例如，该第二触控子电极121的形状和尺寸相同。该触控显示面板还包括多个触控感应电极21，触控感应电极21在阵列基板10上的投影位于第二触控驱动电极12b内的相邻的第二触控驱动子电极121的间隙处。根据本发明实施例的内嵌式触控显示面板将图1和图2所示的内嵌式触控显示面板中的公共电极13也作为了触控驱动电极，在显示阶段时，向第一触控驱动电极12a和第二触控驱动电极12b加载公共电极信号以实现显示功能；在触控阶段时，向第一触控驱动电极12a和第二触控驱动电极12b加载触控信号以实现触控功能。由于这种设置增大了触控驱动电极的面积，并使得触控驱动电极与触控感应电极之间的距离更近，从而提高了边缘互电容，提升了触控灵敏度。图4仅示例性地说明本发明的实施例，而并非对本发明进行任何限制，本领域技术人员应当理解，触控感应电极不一定设置在彩膜基板上，也可以设置在阵列基板上，只要不与触控驱动电极接触即可。
在一个实施例中，为了不影响显示面板的开口率，触控感应电极21设置为与彩膜基板的黑矩阵22的位置相对应，如图4所示。由于触控感应电极21在阵列基板10上的投影位于相邻第二触控驱动子电极121的间隙处，因此，该间隙的位置与黑矩阵22的位置相对应。需要注意的是，图4中只是示意性地示出了触控感应电极和间隙所对应位置的黑矩阵，但本发明实施例不限于此，本领域技术人员应当理解，黑矩阵还位于R、G、B像素之间的其他位置。
从图3可以更清楚地看出根据本发明的实施例的内嵌式触控面板的触控驱动电极的图案。如图3所示，触控感应电极21沿与第一方向X垂直的第二方向Y延伸。在一个实施例中，第一方向X与阵列基板上的数据线的延伸 方向一致，第二方向Y与阵列基板上的栅线的延伸方向一致。在一个实施例中，各个第一触控驱动电极12a和第二触控驱动电极12b通过第一方向X上的触控驱动信号线14电连接在一起。在一个实施例中，多个第一触控驱动电极12a并排设置，每个第一触控驱动电极12a的形状、尺寸相同。在一个实施例中，多个第二触控驱动电极12b同样并排设置，并且在第一方向X上与第一触控驱动电极12a对齐，并且每个第二触控驱动电极12b的形状、尺寸相同。
在不同实施例中，各个第一触控驱动电极12a的长度或宽度可以为4mm至6mm。在不同实施例中，各个第二触控驱动电极12b的长度或宽度也可以为4mm至6mm，例如，其形状、尺寸与第一触控驱动电极12a相同。例如，所述第一触控驱动电极的形状为正方形或长方形。在不同实施例中，沿第二方向Y，相邻的两个第一触控驱动电极12a和/或相邻的两个第二触控驱动电极12b之间的间距为4μm至8μm，并且该间距与彩膜基板20的黑矩阵22的位置相对应，这样可以避免影响显示效果。各个触控感应电极21沿与第一方向X垂直的第二方向Y延伸，从而将第二触控驱动电极12b分为多个第二触控驱动子电极121，第二触控驱动电极12b内的第二触控驱动子电极121之间的间距对应于触控感应电极21的线宽。
在一个实施例中，第一触控驱动电极12a和第二触控驱动电极12b上还设置有电极保护层16，该电极保护层16可以与像素电极层同层制作，且与像素电极层不连接。由于像素电极层通常采用ITO、IGZO等材料形成，在第一和第二触控驱动电极12a、12b上设置电极保护层可以防止触控驱动电极被氧化，使得工艺稳定性更好，并且在一定程度上也降低了电阻。本领域技术人员可以理解，也可以在形成像素电极层的同时，在其他电极层或焊盘上形成像素电极层作为保护层，例如在边缘区域的焊盘上形成像素电极层作为保护层，从而可以在防止电极或焊盘氧化的同时，降低电极或焊盘的电阻。
在图3中，同一行的第一触控驱动电极12a和第二触控驱动电极12b通过至少一根沿第一方向X的触控驱动信号线14电相连。在一个实施例中，触控驱动信号线14与第一触控驱动电极12a和第二触控驱动电极12b同层制备，触控驱动信号线14连接相邻的第一触控驱动电极和第二触控驱动电极，且触控驱动信号线14与触控感应电极21绝缘设置。例如，可以在触控驱动 信号线14与触控感应电极21相对应的位置设置过孔，通过所述过孔、触控感应电极21下层对应的金属层与触控驱动信号线14连接相邻的第一触控驱动电极和第二触控驱动电极，这样不仅可以减少工艺步骤，还有利于使触控面板的边框更窄。本领域技术人员应当理解，触控驱动信号线不限于一根，也可以是同一行第一触控驱动电极和第二触控驱动电极通过多根触控驱动信号线14电连接。
本发明的至少一个实施例还提供了一种内嵌式触控显示面板的驱动方法。该驱动方法可以应用于如上所述的触控显示面板。在该方法中，可以将触控显示面板显示每一帧图像的时间分成显示阶段和触控阶段，此时该方法可以包括：在显示阶段，向第一触控驱动电极12a和第二触控驱动电极12b同时加载公共电极信号；在触控阶段，向第一触控驱动电极12a和第二触控驱动电极12b同时加载触控扫描信号。触控显示面板的触控感应电极可以一直加载公共电极信号，这样形成的有效互容是触控驱动电极与触控感应电极边缘形成的电场部分。在根据本发明实施例的触控显示面板中，由于图1和图2所示的公共电极部分也作为触控驱动电极，这使得边缘电场大大增加，提高了触控灵敏度。
在一个实施例中，所述内嵌式触控显示面板的驱动方法还可以包括：在显示阶段，对显示面板中的栅极信号线施加栅扫描信号，对数据线施加灰阶信号；在触控阶段，显示面板中的每条栅极信号线和数据信号线无信号输入。
本发明的至少一个实施例进一步提供了一种显示装置，其包括如上所述的内嵌式触控显示面板。该显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明实施例通过将图1和图2所示的公共电极作为触控驱动电极，增大了触控感应电极与触控驱动电极之间的互容，从而提高了触控灵敏度，给用户提供了良好的触控体验。
虽然结合附图描述了本发明的实施方式，但是本领域技术人员可以在不脱离本发明的精神和范围的情况下作出各种修改和变型，这样的修改和变型均落入由所附权利要求所限定的范围之内。
