Description

一种阵列基板及自容式内嵌触控显示面板
本发明要求2017年03月10日递交的发明名称为“一种阵列基板及自容式内嵌触控显示面板”的申请号CN201710142299.8的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明属于触控显示技术领域，具体地讲，涉及一种阵列基板及自容式内嵌触控显示面板。
背景技术
现有的自容式内嵌触控显示面板，请参见图1和图2，包括阵列基板，所述阵列基板包括基板110、驱动单元120、公共电极层和多条引线140，所述驱动单元120、公共电极层和多条引线140位于基板110上，所述驱动单元120用于输出触控信号和共通电压，所述公共电极层包括多个触控组，所述触控组呈长条形，其包括多个间隔设置且沿从上往下方向延伸的多个触控电极130，所述触控电极130除了具有实现触控作用外，还兼顾作为像素电容的共通电极，多个所述触控电极130用于分时的接收触控信号和共通电压，当所述触控电极130用作触控作用时，所述触控电极130用于接收触控信号，当所述触控电极130用作像素电容的共通电极时，所述触控电极130用于接收共通电压，所述引线140用于电连接触控电极130和驱动单元120。现有引线140在阵列基板上的走线方式有两种。
其中一种请参见图1，所述引线140的长度等长，均从每个触控组远离驱动单元120一端延伸到与驱动单元120电连接，也即，每条引线140均贯穿整组触控电极130，也即每条引线140跨过的触控电极130数目相同，此种方式称作贯穿方式。这种引线140走线方式，因为引线140较长，触控电极130作为触控作用时导致RC loading(电阻电容负载)较大，从而触控信号在传输中失真较大，这样导致触控特性较差，但是，此种方式由于触控电极130还兼做共通电极，因引线140均从每个触控组远离驱动单元120一端延伸到与驱动 单元120电连接，从而触控电极130上的共通电压均匀，画面的显示效果较好。
另外一种请参见图2，与每个触控组内的触控电极130电连接的引线140不等长，具体位置从左到右引线140逐渐减短，也即引线140跨过的触控电极130的数目从左到右逐渐减少，此种方式称作非贯穿方式。这种引线140走线方式，因为与每个触控组内的触控电极130电连接的引线140逐渐减短，触控电极130作为触控作用时导致RC loading较小，从而触控信号在传输中失真较小，触控特性较好，但是，此种方式由于触控电极130还兼做共通电极，由于引线140不等长，触控电极130上的共通电压均匀性较差，导致画面的显示效果较差。

本申请说明书、权利要求书和附图中出现的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，术语“第一”、“第二”和“第三”等是用于区别不同的对象，而并非用于描述特定的顺序。
第一实施例
本发明实施例提供的自容式内嵌触控显示面板，包括阵列基板。请参见图3和图4，所述阵列基板包括基板210、驱动单元220、公共电极层、多条引线240和至少一条补偿线250。
所述基板210可以为硬性基板210，例如为玻璃基板210，也可以为柔性基板210，例如为聚酰亚胺塑料基板210。
所述驱动单元220位于所述基板210上，例如位于基板210的下侧或上侧等，所述驱动单元220用于输出触控信号和第一共通电压，所述触控信号用于输出给后面提到的触控电极230以侦测是否有触控产生，所述第一共通电压用于提供给触控电极230以让触控电极230作为像素电容的共通电极使用。
所述公共电极层设置在所述基板210上，所述公共电极层包括间隔设置的多个触控电极230，所述多个触控电极230彼此电性绝缘，在本实施例中，所述触控电极230呈长方形，所述触控电极230具有侦测触控的作用，也即作为触控电极230，也具有显示的作用，即作为像素电容的共通电极，也即在本实施例中所述触控电极230具有两个作用，从而有利于触控显示面板的轻薄化，且可以降低成本。多个所述触控电极230用于分时接收触控信号和第一共通电压，例如在第一时间段所述触控电极230用于接收触控信号，在第二时间段所述触控电极230用于接收第一共通电压，第一时间段和第二时间段不同，在本实施例中，所述第一时间段和第二时间包含在自容式内嵌触控显示面板的一个帧(frame)中。在本实施例中，触控电极230上接收的触控信号和第一共通电压 由驱动单元220输出。
多条所述引线240设置在所述基板210上且沿第一方向(图中箭头方向)延伸，在本实施例中，所述第一方向为从上往下的方向，也即所述引线240由上往下延伸，但本发明不限于此，在本发明的其他实施例中，所述第一方向也可以为从下往上的方向。每条引线240的两端分别对应电连接所述触控电极230和所述驱动单元220，从而根据触控电极230与驱动单元220的距离不同，对应的引线240长度也不同，也即不同长度的引线240与触控电极230重叠的面积相异。所述引线240用于传递驱动单元220输出的信号。
在本实施例中，为了减轻触控电极230上第一共通电压均匀性较差的问题，至少一条所述补偿线250位于所述基板210上，其与所述引线240间隔设置，也即引线240与所述补偿线250电性绝缘，也即所述引线240上传递的触控信号或者第一共通电压信号不会传递到补偿线250上来，在本实施例中，所述补偿线250的数目为一条，当然，在本发明的其他实施例中，所述补偿线的数目还可以为多条，例如2条、3条、4条、10条、20条等。在本实施例中，所述补偿线250沿背向所述第一方向延伸，也即所述补偿线250从下往上延伸，所述补偿线250与至少一个触控电极230重叠，在本实施例中，该条所述补偿线250与多个触控电极230重叠，当然，在本发明的其他实施例中，所述补偿线还可以与一个触控电极的部分重叠、与一个触控电极重叠、与两个触控电极重叠、与三个触控电极重叠。在这里，补偿线250与一个触控电极230重叠是指补偿线250贯通所述触控电极230或者不贯通所述触控电极230。所述触控电极230接收第一共通电压时所述补偿线250用于接收第二共通电压，所述第二共通电压等于第一共通电压，例如都为5V，所述第二共通电压可以来源于驱动单元220，也可以不来源于驱动单元220。
在本实施例中，由于每条引线240的两端分别对应电连接其中一个所述触控电极230和所述驱动单元220，从而所述引线240的走线方式为非贯穿方式，触控电极230作为触控作用时RC loading较小，从而触控信号在传输中失真较小，触控特性较好；而且，所述补偿线250与至少一个触控电极230重叠，所述触控电极230接收第一共通电压时所述补偿线250接收第二共通电压，所述第一共通电压等于第二共通电压，从而，所述补偿线250传递的第二共通电压 可以对与其重叠的触控电极230上的第一共通电压进行加强，从而可以改善触控电极230上的第一共通电压均匀性较差的问题，从而画面的显示效果得到改善。
在本实施例中，所述补偿线250与其中一条引线240对应设置，具体为与最短的一条引线240对应设置，所述补偿线250正对最短那条引线240设置，也即补偿线250位于最短那条引线240的延长线上。当然，在本发明的其他实施例中，所述补偿线还可以略微偏移正对那条引线，也即所述补偿线还可以位于对应引线的一侧。
在本实施例中，所述阵列基板还包括控制开关280，所述控制开关280的控制端用于接入控制电压以控制其开启或关闭，所述控制开关280的输入端用于接收第二共通电压，所述控制开关280的输出端用于电连接所有所述补偿线250，在本实施例中，所述控制开关280为薄膜晶体管，所述薄膜晶体管的数量为一个，所述补偿线250的数量为一个。在本发明的其他实施例中，所述控制开关还可以为MOS管等。
在本实施例中，所述触控电极230在基板210上形成M组，每组包括N个触控电极230，也即具有M*N个触控电极230，其中M、N≥2，例如M为2、3、6、8、10、20等正整数，所述N为2、3、6、8、10、20等正整数。每组内的N个所述触控电极230沿第一方向排列，在本实施例中，由于所述第一方向为从上到下的方向，从而每组内的N个所述触控电极230形成一列。所述引线240的数目为M*N条，每条引线240单独电连接一个触控电极230，也即触控电极230与引线240具有一一对应电连接的关系。在本实施例中，驱动单元220位于所述触控电极230的下侧，引线240的一端电连接对应的所述触控电极230，从而，与同一组中的触控电极230电连接的引线240长度呈递减排列或者递增排列，在本实施例中，与同一组中的触控电极230电连接的引线240长度呈递减排列。请继续参见图3，在第一组(列)触控电极230中，与第一个触控电极230电连接的引线240(从左边数起第一条引线240)最长，与第二个触控电极230电连接的引线240(从左边数起第二条引线240)次长，与第三个触控电极230电连接的引线240(从左边数起第三条引线240)继续 减短，…，与第N个触控电极230电连接的引线240(从左边数起第N条引线240)最短，其他组中的引线240长度排列顺序与第一组相同，也即最长的引线240数目、次长的引线240数目、…、最短的引线240数目分别有M条。在本实施例中，所述第一方向为从上到下的方向，但本发明不限于此，在本发明的其他实施例中，所述第一方向还可以为从下到上的方向，或者，所述第一方向可以为从左到右的方向，或者所述第一方向可以为从右到左的方向，等。
在本实施例中，所述引线240在基板210上的层级与所述触控电极230在基板210上的层级相异，例如所述引线240位于所述触控电极230的上方或者下方，所述引线240与所述触控电极230之间设有绝缘层，通过对绝缘层挖贯通孔实现引线240与触控电极230之间的电连接。在本实施例中，所述补偿线250与所述引线240在基板210上位于同一层。当然，在本发明的其实施例中，所述补偿线250与所述引线240在基板210上还可以位于不同层，例如所述引线240位于所述触控电极230的下方，所述补偿线250位于所述触控电极230的上方。
在本实施例中，请继续参见图3，所述阵列基板还包括至少一条悬浮线270，所述悬浮线270线由引线240与触控电极230电连接的一端背向所述第一方向延伸，也即所述悬浮线270由下向上延伸，所述悬浮线270与对应的所述引线240电连接，所述悬浮线270可以与对应的所述引线240一体成型，所述悬浮线270与所述补偿线250绝缘设置，也即两者没有进行电性连接。在本实施例中，所述悬浮线270不是与补偿线250相对的引线240电连接，也即悬浮线270对应的引线240无补偿线250与该引线240对应，也即悬浮线270电连接的引线240无补偿线250与该引线240对应，具体说来，在第一组触控电极261230中，第一条引线240延伸出一条悬浮线270，第一条引线240没有补偿线250与其相对，一条所述补偿线250是与第N条引线240相对。但本发明不限于此，在本发明的其他实施例中，请参见图5，所述悬浮线470还可以是与补偿线450相对的引线240电连接，此时所述悬浮线470位于对应补偿线450与对应所述引线240之间。在本实施例中，所述悬浮线270的长度较短，例如为1微米-1000微米，例如为1微米、10微米、100微米、1000微米等，所述悬浮线270不能太长，不然当悬浮线270数目较多时会引起触控信号 的失真。在本实施例中，悬浮线270的设置也可以用于使触控电极230上第一共通电压较均匀。所述悬浮线270的数目可以为多条，也可以为一条，所述悬浮线270所处的层级与所述引线240所处的层级相同。
在本实施例中，一条补偿线250与一条引线240相对是指补偿线250的下端与该引线240的上端距离上最近，例如在图3中，所述补偿线250是与第N条所述引线240为相对设置。
在本实施例中，由于所述补偿线250的数目为一条，从而补偿线250上的第二共通电压对画面的显示效果改善有限，以下描述第二实施例，以进一步改善画面的显示效果。
第二实施例
图6为本发明第二实施例提供的一种阵列基板，图6的结构与图3的结构相似，因此相同的元件符号代表相同的元件，本实施例与第一实施例的主要不同点为补偿线350的数目。
请参见图6和图7，在本实施例中，所述补偿线350的数目为多个，所述补偿线350分别对应不同的引线240间隔设置。在本实施例中，所述补偿线350的数目与所述引线240的数目相同，也即所述补偿线350的数目也有N*M条，所述N*M条补偿线350一一对应N*M条引线240设置。但本发明不限于此，在本发明的其他实施例中，所述补偿线的数目还可以小于所述引线的数目，也可以大于所述引线的数目。
在本实施例中，所述补偿线350正对一条所述引线240设置，也即所述补偿线350位于对应的引线240的延长线上，所述补偿线350的长度与对应的所述引线240的长度负相关，由于与同一组中的触控电极230电连接的引线240长度呈递减排列，从而，在本实施例中，在同一组中所述补偿线350长度呈递增排列，从而在同一组中不同所述补偿线350与触控电极230的重叠面积相异，在本实施例中，所述补偿线350与所述引线240呈互补关系，任意一条引线240与与其对应的补偿线350长度之和均相等或者近似相等，所述补偿线350靠近对应引线240的一端与所述引线240靠近对应补偿线350的一端位于同一触控电极230的上方或下方。在本实施例中，任意两组中补偿线350的排列方 式相同或相似，由于具有M组，从而任意一种长度的补偿线350的数目为M条，例如，对应第2组-第M组中第一条补偿线350(从左边数起第一条补偿线350)的长度与对应第一组中第一条补偿线350的长度相同，也即与触控电极230重叠的面积相等；对应第2组-第M组中第二条补偿线350(从左边数起第二条补偿线350)的长度与对应第一组中第二条补偿线350的长度相同，也即与触控电极230重叠的面积相等，对应第一组中第一条补偿线350的长度小于第二条补偿线350的长度；对应第2组-第M组中第三条补偿线350(从左边数起第三条补偿线350)的长度与对应第一组中第三条补偿线350的长度相同，也即与触控电极230重叠的面积相等，对应第一组中第二条补偿线350的长度小于第三条补偿线350的长度；…；对应第2组-第M组中第N条补偿线350(从左边数起第N条补偿线350)的长度与对应第一组中第N条补偿线350的长度相同，也即与触控电极230重叠的面积相等，对应第一组中第N-1条补偿线350的长度小于第N条补偿线350的长度。对应同一组中所述补偿线350与触控电极230重叠的面积相异，但对应所述补偿线350来说，所述补偿线350与触控电极230重叠的面积部分相同、部分相异。另外，在本发明的其他实施例中，所有所述补偿线的长度可以完全相同，也即所有所述补偿线与触控电极重叠的面积相等，例如对应每组触控电极仅有一条补偿线，所述补偿线对应最后一条引线设置，该些补偿线的长度与本实施例中每组中的最后一条补偿线长度相等。另外，在本发明的其他实时中，所有所述补偿线的长度可以完全不同，也即所有所述补偿线与触控电极重叠的面积相异，例如只有N条补偿线，所述N条补偿线的排列顺序与本实施例中一组触控电极中的补偿线的排列顺序相同。
另外，在本实施例中，所述阵列基板不包括第一实施例中的悬浮线。
需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
通过上述实施例的描述，本发明具有以下优点：
由于每条引线的两端分别对应电连接其中一个所述触控电极和所述驱动单元，从而所述引线的走线方式为非贯穿方式，触控电极作为触控作用时RC loading较小，从而触控信号在传输中失真较小，触控特性较好；而且，所述补偿线与至少一个触控电极重叠，所述触控电极接收第一共通电压时所述补偿线接收第二共通电压，所述第一共通电压等于第二共通电压，从而，所述补偿线传递的第二共通电压可以对与其重叠的触控电极上的第一共通电压进行加强，从而可以改善触控电极上的第一共通电压均匀性较差的问题，从而画面的显示效果得到改善。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
