Description

基板及显示装置 技术领域
本公开涉及显示领域，尤其涉及一种基板及显示装置。
背景技术
随着显示技术的飞速发展，触摸屏已经逐渐深入到人们的生活当中。如图1所示，目前的触摸屏的触控结构通常包括衬底基板和触摸图形。触摸图形由触控电极构成。触控电极包括触控驱动电极(Tx)和触控感应电极(Rx)。这些触控电极通过信号线(走线)连接到触控驱动电路。例如，如图1所示，每一个触控驱动电极Tx两端中的每一端通过一条信号线20与触控驱动电路10相连。然而，由于不同的触控电极与触控驱动电路的距离不同，因此，不同触控电极所使用的信号线的长度也不同，从而造成触摸屏不同通道(每一个通道包括一个触控电极以及将该触控电极与触控驱动电路相连的信号线)的通道电阻不同。
随着触摸屏技术的发展，人们对触摸屏性能的要求越来越高。因此，触摸屏也具有了更多的功能，比如悬浮触控、防水功能、支持主动笔、被动笔等功能。随着触摸屏功能的增加，对触摸屏的设计也提出了更多的要求。最显著的要求之一就是提高触摸屏通道电阻的均一性。

具体实施方式
下面结合附图和实施例，对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开，但不用来限制本公开的范围。
本公开实施例提供了一种基板，包括至少一条母信号线，至少一条母信号线中的每一条母信号线包括多条相互并联的子信号线。
通过在母信号线中设置多条相互并联的子信号线，能够通过相互并联的子信号线有效降低母信号线的电阻，从而有利于提高触摸屏通道电阻的均一性。
本公开实施例中的基板可以为触摸屏，比如电容式触摸屏。基板还可以包括触控驱动电路以及多个触控电极。多个触控电极中的至少一个触控电极通过至少一条母信号线与触控驱动电路相连。至少一条母信号线中的每一条母信号线包括多条相互并联的子信号线。
多个触控电极可以包括多个触控驱动电极。例如，为了提高触摸屏中触控驱动电极的通道电阻的均一性，可以使触摸屏中的多个触控驱动电极采用上述的母信号线与触控驱动电路相连。根据本公开的实施例，多个触控驱动电极中的每一个触控驱动电极通过至少一条母信号线与触控驱动电路相连。
参见图2，图2是本公开一个实施例提供的一种基板(触摸屏)的示意图。该基板包括N(N大于3)个触控驱动电极(Tx1，Tx2，....，TxN)和M(M大于3)个触控感应电极(Rx1，Rx2，....，RxM)。
为提高触摸屏中触控驱动电极的通道电阻的均一性，可以使N个触控驱动电极中的多个触控驱动电极分别通过多条母信号线与触控驱动电路10相连，多条母信号线中的每一条包括多条相互并联的子信号线。
例如，如图2所示，和触控驱动电极TxN相比，由于触控驱动电极Tx1，Tx2，....，Tx(N-1)与触控驱动电路10的距离较远，因此，可以使触控驱动电极Tx1，Tx2，....，Tx(N-1)中的每一个触控驱动电极的两端中的每一端通过一条母信号线与触控驱动电路10相连。例如，如图2所示，触控驱动电极Tx1的两端中的每一端通过一条母信号线21与触控驱动电路10相连，触控驱动电极Tx2的两端中的每一端通过一条母信号线22与触控驱动电路10相连。
每一条母信号线包括第一部以及与第一部串联的第二部。第二部包括多条相互并联的子信号线。例如，参见图3，图3是图2中虚线框内的放大示意图。用于连接触控驱动电极Tx1与触控驱动电路10的母信号线21包括第一部21a以及与第一部21a串联的第二部21b。第一 部21a可以为如图3所示的单根金属线，第二部21b包括多条相互并联的子信号线211。用于连接触控驱动电极Tx2与触控驱动电路10的母信号线22包括第一部22a以及与第一部22a串联的第二部22b。第一部22a可以为如图3所示的单根金属线，第二部22b包括多条相互并联的子信号线221。通过采用上述的母信号线，可减小信号线的电阻，这有利于提高触摸屏通道电阻的均一性。每一条子信号线的宽度可以约为8μm-30μm，例如可以为20μm。
另外，由于在触控驱动电极Tx1，Tx2，....，Tx(N-1)中，每一个触控驱动电极与触控驱动电路10的距离不同，因此，不同的触控驱动电极的信号线的走线长度也不同。为进一步提高触控驱动电极的通道电阻的均一性，可以根据触控驱动电极与触控驱动电路10的距离而对母信号线中的子信号线的数量进行设置。例如，在上述的基板(触摸屏)中，对于连接不同触控驱动电极的任意两条母信号线，用于连接远离触控驱动电路的触控驱动电极的母信号线所包含的子信号线的数量多于用于连接靠近触控驱动电路的触控驱动电极的母信号线所包含的子信号线的数量。例如，对于相邻的两个触控驱动电极，远离触控驱动电路的触控驱动电极所使用的每一条母信号线中的子信号线的数量比靠近触控驱动电路的触控驱动电极所使用的每一条母信号线中的子信号线的数量多一条。由此，可以进一步地减轻或避免由于不同触控驱动电极与触控驱动电路的距离不同造成的触摸屏通道电阻不均的问题。
另外，为了降低制作难度，提高良率，还可以对触摸屏中的触控驱动电极进行分组，将所有触控驱动电极中的多个触控驱动电极划分为至少两组触控驱动电极。对于连接同一组中不同的触控驱动电极的任意两条母信号线，两条母信号线所包含的子信号线的数量相同。对于连接不同组中不同的触控驱动电极的任意两条母信号线，用于连接远离触控驱动电路的触控驱动电极的母信号线所包含的子信号线的数量多于用于连接靠近触控驱动电路的触控驱动电极的母信号线所包含的子信号线的数量。
例如，对于采用36个(即N＝36)触控驱动电极Tx1，Tx2，....，Tx36的触摸屏而言，可以按照从上至下的方向依次设置触控驱动电极，而触控驱动电路可以设置在触摸屏下部的中间位置。可以将触控驱动 电极Tx1，Tx2，....，Tx35分为三组，第一组触控驱动电极包括Tx1，Tx2，....，Tx12这12个触控驱动电极，第二组触控驱动电极包括Tx13，Tx14，....，Tx24这12个触控驱动电极，第三组触控驱动电极包括Tx25，Tx26，....，Tx35这11个触控驱动电极。第一组触控驱动电极中的每一个触控驱动电极所使用的每一条母信号线可以包含6-8条子信号线，第二组触控驱动电极中的每一个触控驱动电极所使用的每一条母信号线可以包含3-5条子信号线，第三组触控驱动电极中的每一个触控驱动电极所使用的每一条母信号线可以包含2条子信号线。而触控驱动电极Tx36由于距离触控驱动电路最近，因此仍采用现有的信号线设计方式。通过上述结构，不但能够提高触摸屏的触控驱动电极的通道电阻的均一性，而且还能降低制作工艺的难度，提高良率。
根据另一实施例，为了进一步地减小母信号线的电阻，提高触摸屏通道电阻的均一性，每一条母信号线可以包括多个相互串联的第二部。
例如，参见图4，母信号线包括多个相互串联的第二部21b，并且对于母信号线中任意两个相邻的第二部21b，远离触控驱动电路的第二部包含的子信号线的数量多于靠近触控驱动电路的第二部包含的子信号线的数量。
例如，对于每一条母信号线中任意两个相邻的第二部，远离触控驱动电路的第二部包含的子信号线的数量是靠近触控驱动电路的第二部包含的子信号线数量的2倍。例如，母信号线可以采用如图5所示的结构。
另外，为提高触摸屏中触控感应电极的通道电阻的均一性，可以使触摸屏中的多个触控感应电极采用上述的母信号线。多个触控感应电极中的每一个触控感应电极通过至少一条母信号线与触控驱动电路相连。
参见图6，图6是本公开一个实施例提供的另一种基板(触摸屏)的示意图。该基板包括N(N大于3)个触控驱动电极(Tx1，Tx2，....，TxN)和M(M大于3)个触控感应电极(Rx1，Rx2，....，RxM)。
为提高触摸屏中触控感应电极的通道电阻的均一性，可以使M个触控感应电极中的多个触控感应电极分别通过多条母信号线与触控驱动电路10相连。多条母信号线中的每一条包括多条相互并联的子信号 线。
例如，如图6所示，由于位于触摸屏两侧区域的触控感应电极相比位于触摸屏中间区域的触控感应电极与触控驱动电路10的距离较远，因此，可以使位于触摸屏两侧区域的多个触控感应电极中的每一个触控感应电极分别通过一条母信号线与触控驱动电路10相连。例如，如图6所示，触控感应电极Rx1通过一条母信号线31与触控驱动电路10相连，触控感应电极Rx2通过一条母信号线32与触控驱动电路10相连。
每一条母信号线包括第一部以及与第一部串联的第二部。第二部包括多条相互并联的子信号线。例如，参见图7，图7是图6中虚线框内的放大示意图。用于连接触控感应电极Rx1与触控驱动电路10的母信号线31包括第一部31a以及与第一部31a串联的第二部31b。第一部31a可以为如图7所示的单根金属线，第二部31b包括多条相互并联的子信号线311。用于连接触控感应电极Rx2与触控驱动电路10的母信号线32包括第一部32a以及与第一部32a串联的第二部32b。第一部32a可以为如图7所示的单根金属线，第二部32b包括多条相互并联的子信号线321。通过采用上述的母信号线，能够减小信号线的电阻，这有利于提高触摸屏通道电阻的均一性。每一条子信号线的宽度可以约为8μm-30μm，例如可以为20μm。
为进一步地提高触控感应电极的通道电阻的均一性，可以根据触控感应电极与触控驱动电路10的距离对母信号线中的子信号线的数量进行设置。例如，在上述的触摸屏中，对于连接不同触控感应电极的任意两条母信号线，用于连接远离触控驱动电路的触控感应电极的母信号线所包含的子信号线的数量多于用于连接靠近触控驱动电路的触控感应电极的母信号线所包含的子信号线的数量。例如，对于相邻的两个触控感应电极，远离触控驱动电路的触控感应电极所使用的每一条母信号线中的子信号线的数量比靠近触控驱动电路的触控感应电极所使用的每一条母信号线中的子信号线数量多一条，从而可以进一步地减轻或避免由于不同触控感应电极与触控驱动电路的距离不同造成的触摸屏通道电阻不均的问题。
另外，为了降低制作难度，提高良率，还可以对触摸屏中的触控感应电极进行分组。将所有触控感应电极中的多个触控感应电极划分 为至少两组触控感应电极。对于连接同一组中不同的触控感应电极的任意两条母信号线，两条母信号线所包含的子信号线的数量相同。对于连接不同组中不同的触控感应电极的任意两条母信号线，用于连接远离触控驱动电路的触控感应电极的母信号线所包含的子信号线的数量多于用于连接靠近触控驱动电路的触控感应电极的母信号线所包含的子信号线的数量。
例如，对于采用64个(即M＝64)触控感应电极Rx1，Rx2，....，Rx64的触摸屏而言，可以按照从左至右的方向依次设置触控感应电极。触控驱动电路可以设置在触摸屏下部的中间位置。可以将位于显示面板左侧区域的触控感应电极Rx1，Rx2，....，Rx30以及位于显示面板右侧区域的触控感应电极Rx35，Rx36，....，Rx64分为三组。第一组触控感应电极包括Rx1，Rx2，....，Rx10以及Rx55，Rx56，....，Rx64这20个触控感应电极。第二组触控感应电极包括Rx11，Rx12，....，Rx20以及Rx45，Rx46，....，Rx54这20个触控感应电极。第三组触控感应电极包括Rx21，Rx22，....，Rx30以及Rx35，Rx36，....，Rx44这20个触控感应电极。第一组触控感应电极中的每一个触控感应电极所使用的每一条母信号线可以包含6-8条子信号线。第二组触控感应电极中的每一个触控感应电极所使用的每一条母信号线可以包含3-5条子信号线。第三组触控感应电极中的每一个触控感应电极所使用的每一条母信号线可以包含2条子信号线。而位于触摸屏中间区域的触控感应电极Rx31，Rx32，....，Rx34由于距离触控驱动电路最近，因此，仍采用现有的信号线设计方式。通过上述结构，不但能够提高触摸屏中触控感应电极的通道电阻的均一性，还能降低制作工艺的难度，提高良率。
根据另一实施例，为了进一步地减小母信号线的电阻，提高触摸屏通道电阻的均一性，上述触摸屏中的每一条母信号线可以包括多个相互串联的第二部。
根据另一实施例，对于每一条母信号线中任意两个相邻的第二部，远离触控驱动电路的第二部包含的子信号线的数量多于靠近触控驱动电路的第二部包含的子信号线的数量。
例如，对于每一条母信号线中任意两个相邻的第二部，远离触控驱动电路的第二部包含的子信号线的数量是靠近触控驱动电路的第二 部包含的子信号线数量的2倍。
根据本公开实施例的母信号线不但适用于目前普通边框的触摸屏，而且尤其适用于目前的窄边框产品。随着窄边框技术的发展，触摸屏上的信号线也越来越细。而越来越细的信号线会使触摸屏通道电阻的不均进一步地加剧。通过根据本公开实施例的母信号线，可以有效减轻或避免由于信号线变细和膜层方阻改变带来的不良影响，降低由于信号线变细对触摸屏通道电阻均一性带来的不良影响，并且还能够增强信号线的附着力，避免发生信号线的脱落(peeling)。
本公开实施例提供的触摸屏可以为任意结构的触摸屏，比如电容式触摸屏。例如，本公开一个实施例提供的触摸屏可以为OGS结构的触摸屏。参见图8，该触摸屏包括衬底基板1以及依次设置在所述衬底基板1上的遮光层(BM)2、架桥层(Bridge)3、第一覆盖层(OC1)4、透明导电层5、金属层6以及第二覆盖层(OC2)7。透明导电层5包括多个触控电极，金属层6包括用于连接触控电极与触控驱动电路的母信号线。
上述OGS结构的触摸屏的制作方法可以包括以下步骤。
步骤1：在衬底基板(例如Glass基板)1上制作遮光层(BM)2。主要工序包括涂胶、曝光、显影，从而形成所需要的BM层的图案。
步骤2：制作架桥层(即ITO桥点层)3。主要工序包括ITO镀膜、涂光刻胶、曝光、显影、刻蚀，从而形成所需要的架桥层。
步骤3：制作第一覆盖层(OC1)4。主要工序包括涂胶、曝光、显影，从而形成所需要的第一覆盖层的图案。
步骤4：制作透明导电层5。根据设计的透明导电层图案(ITO Pattern，触摸图案)来制作透明导电层。主要工序包括ITO镀膜、涂光刻胶、曝光、显影、刻蚀，从而形成所需要的透明导电层。在该步骤中，还可以形成相应的压力感应的通道。
步骤5：制作金属层6。主要工序包括金属镀膜，涂光刻胶，曝光，显影，刻蚀，从而形成所需要的金属层6。
步骤6：制作第二覆盖层(OC2)7。主要工序包括涂胶，曝光，显影，从而形成所需要的第二覆盖层的图案。
通过采用根据本公开实施例的母信号线来连接触控电极与触控驱动电路，能够有效降低信号线变细和膜层方阻改变带来的不良影响， 并能够有效增加触摸屏通道电阻的均一性。例如，可以对采用36个触控驱动电极的OGS触摸屏进行测试，触摸屏的尺寸大小为15.6寸。
首先，对采用现有结构(即图1中的结构)的触摸屏进行测试。通过对6块触摸屏(屏幕1-屏幕6)的触控驱动电极的通道电阻进行测试分析，其结果如图9和图10所示。对于图1中的结构，由于Tx1位于最远端，因此，会导致Tx1所在的第一通道的通道电阻是最大的。并且，Tx1所在的第一通道的通道电阻与Tx36所在的第36通道的通道电阻相差非常大。采用这种设计方式，不同通道的通道电阻的差异较大。从图9所示的数据以及图10中的曲线走向可以看出，同一触摸屏中的通道电阻最大值与通道电阻最小值相差约38.7％。所有触摸屏的标准差值均大于1000。可见，采用现有结构的触摸屏的通道电阻的均一性较差。对于支持被动笔和主动笔的触摸屏来说，触控效果会大打折扣。
然后，对采用根据本公开实施例的结构的触摸屏进行测试。触摸屏的触控驱动电极采用母信号线与触控驱动电路相连。通过对6块触摸屏(屏幕11-屏幕16)的触控驱动电极的通道电阻进行测试分析，其结果如图11和图12所示。从图11所示的数据以及图12中的曲线走向可以看出，同一触摸屏的通道电阻的最大值与最小值相差不超过6.05％。所有触摸屏的标准差值很小，约为344-435。因此，对采用根据本公开实施例的结构的触摸屏而言，其通道电阻的均一性较好。因此，根据本公开实施例的触摸屏能够有效降低信号线变细带来的通道电阻之间的差异，对于超窄边框和超窄线宽的设计同样具有通道电阻均一化的效果。对于支持主动笔和被动笔特性的触摸屏来说，根据本公开实施例的触摸屏的设计能够有效提升触摸屏内的通道电阻的均一性，这有利于各种笔的操作信号的传输，并且有利于触控IC的分位调试。
此外，本公开一个实施例还提供了一种显示装置，其可以包括上述基板。该显示装置可以是笔记本电脑显示屏、显示器、电视、数码相框、手机、平板电脑等任何具有显示功能的产品或部件。
以上实施例仅用于说明本公开，而并非是对本公开的限制。有关技术领域的普通技术人员，在不脱离本公开的精神和范围的前提下，还可以做出各种变化和变型。因此，所有的等同技术方案也属于本公 开的范畴。本公开的专利保护范围应由权利要求限定。
