技术领域
本公开涉及显示技术领域，特别涉及一种内嵌式触控屏及其驱动方法。
背景技术
现有技术中，内嵌式(In Cell)触控屏作为未来触控显示器的发展方向，具有轻薄一体高度集成化的优势。在In Cell产品中多将触控屏的触控驱动电极与公共电极共用同一电极，并且，为了避开共用的电极中在显示功能和触控功能之间的相互干扰，目前的In Cell多采用分时驱动的方式进行驱动，在一帧显示时间内将一帧时间分成两部分，一部分时间内对电极的通入触控驱动信号使电极层用于触控功能，此时该电极层不能用于显示；另一部分时间内对电极层通入显示驱动信号使电极层用于显示功能，此时该电极层不能用于触控。
上述方式虽然能够避开显示功能和触控功能之间的相互干扰，但是，上述方式使得会使得每一帧时间内电极用于实现触控功能和显示功能的时间都大幅减小，使得电极中触控信号的扫描频率不能太高，进而牺牲了触控屏的触控特性和显示特性，对显示特别是高清显示造成设计困难和画质下降，同时触控性能也难以提高。

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。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一” 等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
请参考图1-图5，本公开实施例提供的内嵌式触控屏包括：
衬底基板1，
形成于衬底基板1上的电极层2，以及
触控驱动模块3；
其中，在电极层2上形成沿触控屏内像素单元的列方向排列的多行电极21；每一行电极21用于驱动内嵌式触控屏的至少一行像素单元；
触控驱动模块3具有与每一行电极21的每个电极一一对应的信号线31，每一行电极21的每个电极都通过信号线31与触控驱动模块3相连接；
在一帧画面的显示时间内，当多行电极中的一行电极21对应的像素单元需要进行显示时，触控驱动模块3用于向该行电极21输入显示驱动信号，同时向其他行的电极21输入触控驱动信号。
具体地，如图1所示，在电极层2上形成沿触控屏的像素单元的列方向排列的m行电极21，如图1中所示的T1行至Tm行。在一帧时间内，例如如图5所示的第N帧时间内，当T1行的电极21对应的一行像素需要进行显示时，触控驱动模块3向T1行电极21内输入显示信号，而向T2、T3...Tm行的电极21内输入触控扫描信号；当T2行的电极21对应的一行像素需要进行显示时，触控驱动模块3向T2行电极21内输入显示信号，而向T1、T3...Tm行的电极21内输入触控扫描信号；以此类推，直至一帧时间结束。各行输入的信号的波形如图5所示，其中T1(a-n)至Tm(a-n)为触控扫描信号。
从中可以看出，在第N帧的整帧时间内，T1行的电极21用做显示扫描的时间占一帧时间的比例为1/m，其他时间均可以用于进行触控扫描，其可用做触控信号扫描的时间占整帧时间的(m-1)/m，从而能够保证T1行电极21在一帧时间内有充足的时间用于进行显示信号扫描和触控信号扫描。
同理，其他行的电极的驱动原理与T1行的驱动原理相同。总之，上述嵌入式触控屏采用的分区驱动的驱动模式能够使每一行电极在一帧内都可以进 行数次触控信号扫描，使得触控信号的扫描频率(报点率)可以数倍于显示信号的扫描频率频率，提高了内嵌式触控屏的显示特性和触控特性。在一种可选实施方式中，每一行电极21还可以用于驱动多行像素单元。可选地，每一行电极21用于驱动的像素单元的行数可以相同。例如，如图2中所示，每一行电极21可以用于驱动N行像素单元。
在一种可选实施方式中，本公开的内嵌式触控屏中还包括栅线驱动模块4。所述栅线驱动模块4通过栅线41向像素单元行提供栅极信号；具体地，栅线驱动模块4根据电极21的行数m被划分为m组，每一个组与一行电极21对应的像素相连接，例如如图2中的G1-Gm所示。每一个组负责向其对应的一行电极21对应的像素单元输送栅极信号。如图2所示，G1组用于向G1/1、G1/2至G1/N栅线中输入信号。在一种可选实施方式中，栅线驱动模块4与触控驱动模块3之间设有信号同步模块。如图5所示，HSYNC和VSYNC是内嵌式触控屏驱动系统的两个同步信号。
当然，如图2、图3和图4所示，上述内嵌式触控屏还包括数据线驱动模块5。数据线驱动模块5向相应的数据线内输入数据信号，以使该行像素单元进行显示。数据线驱动模块5与栅线驱动模块4、触控驱动模块3可以集成于一体，以减小内嵌式触控屏的边框。
在一种可选实施方式中，上述内嵌式触控屏还包括系统模块6和信号协调模块7。如图4所示，当内嵌式触控屏需要进行驱动时，系统模块6通过信号协调模块7将信号同时传输给数据线驱动模块5与栅线驱动模块4，同时触控驱动模块3同时向各电极传输相应的信号。
在上述各实施方式的基础上，在一种可选实施方式提供的内嵌式触控屏中，每一行电极21可以包括多个子电极，具体如图1和图3所示。触控驱动模块3具有与各子电极一一对应的数据线。在上述结构的内嵌式触控屏中，当一行电极21中某一个子电极与触控驱动模块3之间的信号线31损坏时，该行其他的子电极仍然可以正常工作，产品质量较高。
在一种可选实施方式中，各子电极的形状相同；具体地，每一个子电极在衬底基板1上的投影形状可以为方形、长方形、相互拼接的梯形、或者平行四边形等形状。
当然，在一种可选实施方式中，每一行电极21还可以具有一体式结构。
另外，本公开还提供了一种如上述实施方式中提供的任意一种内嵌式触控屏的驱动方法，包括：
当内嵌式触控屏的一行像素单元进行显示时，内嵌式触控屏的触控驱动模块向用于驱动该行像素单元的一行电极输入显示驱动信号，同时，向其他行的电极输入触控驱动信号。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
