如图1所示，采用TDDI技术的触控显示面板使用显示的膜层分时复用来加载TP(Touch Panel，触摸屏)信号，这一膜层分成几百甚至上千个独立的Sensor(电极)块，每个电极块由IC(Integrated Circuit，集成电路) 通过Tx线(触控驱动电极线)供给电学信号，在显示区间为Vcom(公共电极)信号，用于正常显示；而在触控区间则为TP信号，实现触控效果。
然而，由于IC pin(引脚)数量的限制，每个电极块只能通过1根Tx线来供给信号，随着Panel(面板)尺寸的不断增大，到达显示面板的IC对侧区域，即显示区域靠近面板边缘(Panel Edge)的一侧的电极块的距离变长，使得Tx线上的电阻急剧增大，导致Vcom信号到达IC对侧时有部分衰减，出现显示异常，影响显示阶段的正常显示。
如图2所示，本公开一些实施例提供了一种触控显示面板100，该触控显示面板划分有显示区域(Active Area，图中标记为A)、包围显示区域A的非显示区域(图中标记为B)和位于非显示区域B一侧的驱动电路区域(图中标记为C)；该触控显示面板100包括，阵列间隔设置在显示区域A内的多个电极块1，设置在非显示区域B内的环绕显示区域的内公共电极线2，显示区域A与远离驱动电路区域C一侧的内公共电极线2之间具有间隔区域(图中标记为D)；上述触控显示面板100还包括，贯穿显示区域A的多根平行排列的虚设触控驱动电极线3，多根平行排列的虚设触控驱动电极线3中的每根虚设触控驱动电极线3至少与多个电极块1中靠近间隔区域D的每个电极块1一一对应且电性连接；设置在间隔区域D内的与电性连接有一根虚设触控驱动电极线3的各个电极块1一一对应的开关单元(Switch)4，每个开关单元4用于电性连接内公共电极线2与一根虚设触控驱动电极线3。
需要说明的是，第一、上述图2中仅示意出触控显示面板中的电极块1、虚设触控驱动电极线3等结构，其数量不作限定，具体可根据显示产品的设计灵活调整。
第二、内公共电极线2为包围显示区域的环状走线结构，可通过引线与设置在驱动电路区域C内的集成电路IC电性连接，以接收Vcom信号。
第三、为了更清楚地说明上述贯穿显示区域A的多根平行排列的虚设触控驱动电极线3，此处可先参考图1所示的相关技术，在上述相关技术中，电性连接有触控驱动电极线(Tx线)的电极块具有分时复用的功能，即在显示阶段作为公共电极，接收Tx线上传输的公共电极Vcom信号；在触控阶段作为触控电极，接收Tx线上传输的触控驱动信号。
由于一个子像素单元的尺寸非常微小，通常为240μm×240μm的小方块；而人手指与显示屏相接触的区域面积远大于子像素单元的尺寸，因此 触控的识别精度无需识别到子像素单元的尺寸数量级，故为了简化工艺，一个电极块通常对应有数十个像素单元。
由于沿数据线方向的一列像素单元共用一根或若干根Tx线，这样一来，一个电极块的区域内就存在有多根Tx线，但受限于IC引脚pin的数量限制，一个电极块仅与一根Tx线电性连接，从而导致触控显示面板中会有一些Tx线没有与电极块电性连接，这些虚设的驱动电极线即成为了虚设触控驱动电极线(Dummy Tx线)，其走线两端通常通过过孔与前述的环状内公共电极线(inner COM)电性连接。虚设触控驱动电极线的具体数量与一列像素单元共用Tx线的数量、触控显示面板的分辨率以及一个电极块对应的像素单元的具体数量等因素有关。
第四、由于靠近间隔区域D的电极块1即是位于显示区域A中相对于驱动电路区域C的面板的对侧，将靠近间隔区域D的电极块1与相应数量的虚设触控驱动电极线3通过过孔电性连接在一起，再通过开关单元4将电性连接有电极块1的触控驱动电极线3与内公共电极线2连接在一起，从而可将内公共电极线2上的Vcom信号传输给设置在IC对侧的电极块1，从而增加电极块1上的Vcom信号供给。
基于此，通过本公开一些实施例提供的上述触控显示面板，提出了一种新型的Vcom信号供给结构，在面板远离IC的一侧增加了若干开关单元，充分利用面板中闲置的虚设触控驱动电极线，将内公共电极线上的Vcom信号供给显示区域中靠近间隔区域(即IC的对侧)的电极块，可通过设定时序来灵活控制开关单元的打开与关闭，从而可达到增强显示阶段中面板的Vcom信号供给，以改善显示效果；又可保证触控阶段的正常的触控功能。
这里，虚设触控驱动电极线3通常沿列方向排列，与虚设触控驱动电极线3一一对应、且电性连接的电极块1至少为靠近间隔区域的第一行电极块，从而可保证距离IC最远的、发生信号衰减最为严重的一行电极块1能够得到Vcom信号补给。
虚设触控驱动电极线3的数量通常是小于整个面板中的电极块1的数量，因此，虚设触控驱动电极线3只需与靠近间隔区域的电极块1一一对应且电性连接即可，靠近IC端的电极块1上接收到的Vcom信号不会发生衰减，也无需再与闲置的虚设触控驱动电极线3相连。
进一步的，上述开关单元4具体包括输入端和输出端；其中，输入端 与内公共电极线2电性连接；针对任一根电性连接有电极块1的虚设触控驱动电极线3，该根虚设触控驱动电极线3的一端与对应的开关单元4的输出端电性连接，另一端悬空(即与内公共电极线2断开，不接收电信号)，从而保证当上述开关单元4打开时，内公共电极线2上的Vcom信号可通过开关单元4传输到对应的电极块1上。
上述开关单元4还包括控制端；参考图2所示，上述触控显示面板还包括，设置在驱动电路区域的集成电路(IC)5，该集成电路用于控制开关单元4的控制端。
其中，集成电路5具体可以是通过设置在非显示区域的控制端连接走线将每个开关单元4的控制端与集成电路5电性连接，从而可分时控制开关单元4在显示阶段打开或在触控阶段关闭。
这里，集成电路5还可与柔性印刷电路板(Flexible Printed Circuit，简称为FPC)7电性连接，可将柔性印刷电路板弯折到面板的显示背侧，从而进一步提高面板显示区域的屏占比，优化显示体验。
当然，参考图1所示，上述的触控显示面板100还包括，贯穿显示区域的多根平行排列的触控驱动电极线(Tx线)8；其中，每根触控驱动电极线8的一端与每个电极块1电性连接，另一端与集成电路5电性连接。
在上述基础上，本公开实施例还提供了一种基于上述触控显示面板的驱动方法，该驱动方法包括，
在显示阶段，控制开关单元开启，以使内公共电极线上的电信号通过开关单元传输到对应的电极块上；
在触控阶段，控制开关单元关闭，以断开内公共电极线与电极块的连接。
从而可通过设定时序来灵活控制开关单元的打开与关闭，达到增强显示阶段中面板的Vcom信号供给，以改善显示效果；又可保证触控阶段的正常的触控功能。
这里，上述在显示阶段，控制开关单元开启，以使内公共电极线上的电信号通过开关单元传输到对应的电极块上的步骤当然还可包括有，向上述的触控显示面板输入正常的显示信号，以实现显示功能。
上述在触控阶段，控制开关单元关闭，以断开内公共电极线与电极块的连接的步骤当然还可包括有，向上述的触控显示面板输入触控(TP)信号，以实现触控功能。
上述的控制开关单元关闭例如可以是使得开关单元的控制端悬空，不输入电信号。但是在面板的时间显示过程中，面板中会有多种电信号输入到相应的各结构中，且面板中走线布局非常紧凑，有可能会有其他信号误传输到开关单元的控制端，导致该开关单元在触控阶段打开，影响正常的触控功能，因此，本公开实施例进一步优选为，控制开关单元关闭，包括，向开关单元的控制端输入控制信号，使开关单元关闭。
这里，在上述触控阶段输入的控制信号例如可以与显示区域内的TFT的栅极(Gate)信号具有相同频率，这一信号不足以打开开关单元，但可以使得开关单元的控制端信号与其余信号做同步调制(Modulation)，减少对触控信号的干扰。
下面提供两个示例，用于详细描述在不同驱动模式下的上述触控显示面板的具体驱动方法。
示例1：帧间驱动模式
在帧间驱动模式(V_blank模式)中，一帧画面(One Frame)的时间由一个显示阶段(Display)和一个触控阶段(Touch)构成。
如图3所示，在此模式下，相关技术提供的触控显示面板的工作原理为：
首先加入正常显示信号，同没有集成触控功能的普通显示面板(Normal Panel)一致，实现显示功能；即向显示区域内的各数据线输入源极信号(如图中所标记的Source)；依次为每行栅线施加驱动信号(如图中标记的Gate1、Gate2……Gaten、Gaten+1)，使与每行栅线连接的TFT按时序打开，从而按时序依次打开各像素单元；向显示区域内的电极块(此时分时复用为公共电极)输入公共电极信号Vcom，该Vcom信号通常为±5v的恒定电压。
在一帧画面的显示阶段结束后加入触控(TP)信号，实现触控功能，在触控信号加入期间，其余信号均做同步调制(Modulation)，触控阶段结束后进入下一帧。
这里，同步调制是指将除了触控信号的各显示信号均具有相同的频率，以减小对触控信号的干扰。
在此模式下，显示时间与触控时间之和为普通显示面板(Normal Panel)一帧的显示时间，触控一帧报点1次，即在一帧画面的时间(面板的扫面频率为60Hz时，一帧时间约为16.67ms)内识别一次触控点。
如图4所示，在此模式下，本公开一些实施例提供的触控显示面板的工作原理为：
通过向开关单元的控制端输入相应的控制信号，以控制开关单元的开关状态。在显示阶段，控制信号可以为高电平，将开关单元如N型TFT(Thin Film Transistor，薄膜晶体管)打开，从而增强与开关单元相连的一个电极块的Vcom信号供给，其余显示信号与相关技术的原结构中各显示信号一致；在触控阶段，将开关单元如N型TFT的控制信号拉低，并且与其余信号一致，做同步调制，这样不影响触控报点。
这里，在触控阶段，将开关单元如TFT的控制信号拉低具体为，向开关单元的控制端(如TFT的栅极)输入的控制信号与触控阶段的显示区域内的TFT的栅极(Gate)信号具有相同的频率，以实现除触控信号之外的各信号同步调制。
示例2：帧内驱动模式
在帧内驱动模式(H_blank模式)中，一帧画面(One Frame)的时间由多个显示阶段(Display)和穿插在多个显示阶段之间的触控阶段(Touch)构成。
如图5所示，在此模式下，相关技术提供的触控显示面板的工作原理为：
将触控(TP)信号平均分为若干个(如图5中所示的m份)，在一帧时间内插入到显示时间中，即显示先进行一段时间，然后插入触控信号，接着再进行显示，然后再插入触控信号，以此往复，直至所有触控信号均插入，显示结束后进入下一帧。
在此模式下，触控时间的总和要比前述的帧间驱动模式下的触控时间长，但一帧的总时间不变，显示时间要有所缩减，触控一帧报点2次。
如图6所示，在此模式下，本公开一些实施例提供的触控显示面板的工作原理为：
步骤1、将触控信号平均分为m个，m≥2；
步骤2、在一帧画面的第i个显示阶段，输入显示信号并开启开关单元(开启的方式例如为拉高控制信号)，以进行一帧画面的第i部分显示，并使得内公共电极线上的电信号通过开关单元传输到对应的电极块上，从而增强面板远离驱动电路区域一侧的电极块上的Vcom信号供给；
步骤3、在一帧画面的紧邻第i个显示阶段的第i个触控阶段，输入触 控信号分割后的第i个信号，并关闭开关单元，即将开关单元的控制信号拉低，并与其余信号的频率一致，做同步调制；
依次循环执行步骤2、步骤3，直至将一帧画面的所有部分显示完毕；
其中，i从1至m依次取值。
从而可以在增强面板远端电极块上的Vcom信号供给的同时，又不影响一帧画面中触控报点。
需要说明的，上述示例1与示例2均以个开关单元具体为N型TFT为例进行示例说明，即控制信号为高电平打开，在显示阶段拉高控制端(栅极)信号以打开该TFT；低电平关闭，在触控阶段拉低控制端(栅极)信号以关闭该TFT。上述示例对于开关单元具体为P型TFT，即控制信号为低电平打开、高电平关闭的情况同样适用，具体时序部分可沿用相关技术中像素单元采用P型TFT控制的时序方法。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
