Description

内嵌式触摸屏及显示装置 技术领域
本发明实施例涉及一种内嵌式触摸屏及显示装置。
背景技术
随着显示技术的飞速发展，触摸屏(Touch Screen Panel)已经逐渐遍及人们的生活中。通常，触摸屏按照组成结构可以分为：外挂式触摸屏(Add on Mode Touch Panel)、覆盖表面式触摸屏(On Cell Touch Panel)、以及内嵌式触摸屏(In Cell Touch Panel)。外挂式触摸屏是将触摸屏与液晶显示屏(Liquid Crystal Display，LCD)分开生产，然后贴合到一起成为具有触摸功能的液晶显示屏。外挂式触摸屏存在制作成本较高、光透过率较低、模组较厚等缺点。而内嵌式触摸屏将触摸屏的触控电极内嵌在液晶显示屏内部，不仅可以减薄模组整体的厚度，又可以大大降低触摸屏的制作成本，受到各大面板厂家的青睐。
内嵌(In cell)式触摸屏是利用互电容或自电容的原理实现手指触摸位置的检测。利用自电容的原理可以在触摸屏中设置多个同层设置且相互绝缘的自电容电极。当人体未触碰屏幕时，各自电容电极所承受的电容为一固定值。当人体触碰屏幕时，对应的自电容电极所承受的电容为固定值叠加人体电容。触控侦测芯片在触控时间段通过检测各自电容电极的电容值变化可以判断出触控位置。由于人体电容可以作用于全部自电容，相对于人体电容仅能作用于互电容中的投射电容，由人体触碰屏幕所引起的触控变化量会大于利用互电容原理制作出的触摸屏。因此，相对于互电容的触摸屏，自电容的触摸屏能有效提高触控的信噪比，从而提高触控感应的准确性。
但是，通常内嵌(In cell)式触摸屏在制作时，需要针对触控功能提供额外的触控芯片以及电路板。因此，这种设计虽然可以节省整个模组的厚度，但是整体成本却大大提升。

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。

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。
在通常的液晶显示装置、有机发光二极管(OLED)显示装置中，每个点(像素)是由多个子像素通过混光来显示颜色的。例如每个像素由红色子像素、绿色子像素、蓝色子像素各一个组成(RGB模式)。
为了改善视觉效果，人们对于显示装置的分辨率(单位尺寸内的像素数) 提出了越来越高的要求。这就要求子像素的尺寸越来越小，但由于工艺限制子像素尺寸不能无限缩小。
为在子像素尺寸一定的情况下改善显示效果，人们提出了Pentile模式的虚拟显示设计。该模式中，RGB(Red Green Blue，红绿蓝)子像素的排列方式为RGB Pentile波形排列方式，RGB波形排列的单个像素只有“红绿”或者“蓝绿”两个子像素组成。同样显示33个像素，RGB波形排列方式在水平方向只做了6个子像素，而标准RGB子像素排列在水平方向做了9个子像素。与标准RGB子像素排列方式相比，RGB波形排列方式采用的子像素数量减少了1/3。在实际显示图像时，RGB波形排列的一个像素会“借”用与其相邻的像素的另一种颜色来构成三基色，每个像素和相邻的像素共享自己所不具备的那种颜色的子像素，共同达到白色显示。
本发明实施例基于上述虚拟显示设计，提出了一种将虚拟显示技术与触控技术结合在一起的新的内嵌式触摸屏结构。
下面结合附图，对本发明实施例提供的内嵌式触摸屏及显示装置的具体实施方式进行详细地说明。
附图中各膜层的厚度和形状不反映真实比例，目的只是示意说明本发明内容。
本发明实施例提供的一种内嵌式触摸屏，如图1所示，包括相对设置的下基板1和上基板2，以及驱动芯片3。其中，下基板1与上基板2之间具有规律排列的若干子像素01和位于相邻两列子像素01之间的数据线02。各子像素01通过位于其一侧的数据线02与驱动芯片3连接。彼此相邻的两个子像素01组成一个像素，或彼此相邻的三个子像素01组成两个像素。驱动芯片用于在显示时间段通过数据线02向对应的子像素01加载数据信号，使相邻像素之间共用至少一个子像素01。该内嵌式触摸屏还包括：
位于下基板1与上基板2之间相互独立的若干自电容电极03；
以及将各自电容电极03连接至驱动芯片3的导线04；
驱动芯片3还用于在触控时间段通过检测各自电容电极03的电容值变化以判断触控位置。
本发明实施例中的彼此相邻的两个子像素组成一个像素，例如，可以为：同一行子像素中，两个子像素构成一个像素，每个像素“借”用与其相邻的 像素的另一种颜色的子像素来构成三基色。例如，每个像素可“借”用该行子像素中与其相邻的像素的另一种颜色的子像素来构成三基色。但不限于此。
本发明实施例中的彼此相邻的三个子像素组成两个像素，例如，可以为：同一行子像素中，三个子像素构成两个像素，构成该两个像素的三个子像素中，有一个子像素被该两个子像素共用，每个像素“借”用与其相邻的像素的另一种颜色的子像素来构成三基色。例如，每个像素可“借”用该行子像素中与其相邻的像素的另一种颜色的子像素来构成三基色。但不限于此。
本发明实施例提供的上述内嵌式触摸屏，由于每个像素只包括两个子像素或者两个像素包括三个子像素，因此，与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3甚至是1/2的子像素的数量。相应地数据线的数量也可以减少1/3或者1/2。因此可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线，从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。
例如，导线可与数据线同层设置，这样可以在通常制备工艺的基础上，与数据线通过一次构图工艺形成，不需要增加额外的工艺单独制备导线，从而进一步节省生产成本，提高生产效率。
例如，该内嵌式触摸屏中，所述下基板可以为阵列基板，所述上基板可以为对置基板。此时，该内嵌式触摸屏为液晶显示屏。
需要说明的是，液晶显示屏中，对置基板与阵列基板相对设置，对置基板和阵列基板分别为显示面板的上下两个基板，通常在阵列基板上形成薄膜晶体管阵列等显示结构，在对置基板上形成彩色树脂。例如，对置基板为彩膜基板。
例如，该内嵌式触摸屏也可用于电致发光显示屏，此时，所述下基板可为阵列基板，所述上基板可为盖板或封装膜。
本发明实施例提供的上述内嵌式触摸屏，即适用于液晶显示屏，也适用于有机电致发光显示屏，在此不作限定。
进一步地，在具体实施时，当上述内嵌式触摸屏应用于液晶显示屏时，既适用于扭转向列(Twisted Nematic，TN)型液晶显示屏，也适用于高级超维场开关(Advanced Dimension Switch，ADS)型液晶显示屏，同样也适用 于高开口率、高级超维场开关(High-Advanced Dimension Switch，HADS)型液晶显示屏和平面内开关(In-Plane Switch，IPS)型液晶显示屏。
进一步地，在本发明实施例提供的上述内嵌式触摸屏应用于ADS型液晶显示屏时，板状结构的公共电极层位于狭缝状像素电极的下方。即公共电极位于下基板与像素电极之间。并且在公共电极与像素电极之间还设置有钝化层。而应用于HADS型液晶显示屏时，狭缝状的公共电极位于板状结构的像素电极的上方。即像素电极位于下基板与公共电极之间，并且在像素电极与公共电极之间还设置有钝化层。
例如，当本发明实施例提供的上述内嵌式触摸屏应用于ADS型或HADS型液晶显示屏时，为了简化制作工艺，以及降低制作成本，可以采用位于下基板上的公共电极层复用自电容电极。即各自电容电极组成位于下基板面向上基板一侧的公共电极层，驱动芯片还用于在显示时间段对各自电容电极加载公共电极信号。这样，将公共电极层的结构进行变更分割成自电容电极以实现触控功能时，在通常的阵列基板制备工艺的基础上，不需要增加额外的工艺，可以节省生产成本，提高生产效率。
下面通过将本发明实施例提供的上述内嵌式触摸屏应用于HADS模式液晶显示屏为例，来说明上述内嵌式触摸屏。如图2a和图2b所示，包括：相对设置的上基板2和下基板1，以及依次位于下基板1上的栅电极11，栅极绝缘层12，同层且间隔设置的有源层13和像素电极14，同层设置的源漏电极15、数据线02和导线04，钝化层16，以及由自电容电极03组成的公共电极层。其中，自电容电极03通过贯穿钝化层16的过孔与导线04电连接。在实施时，上述内嵌式触摸屏的上基板与下基板之间还包括液晶显示屏的其它必不可少部件，这些均可参见通常设计，在此不再赘述。
例如，本发明实施例提供的上述内嵌式触摸屏中，可以采用通常的任意一种构图流程制作下基板上的各膜层。例如，可以采用6次构图工艺：栅电极构图→有源层构图→像素电极构图→数据线、导线和源漏电极构图→钝化层构图→公共电极层构图。当然也可以根据实际设计，采用5次构图工艺、7次构图工艺或8次构图工艺，在此不做限定。
进一步地，本发明实施例提供的上述内嵌式触摸屏，可以适用于任何虚拟显示设计的子像素排列的显示器件。下面通过几个实施例详细说明本发明 实施例提供的上述内嵌式触摸屏中子像素的具体排布规律。
实例一：
本发明实施例提供的内嵌式触摸屏，如图3a和图3b所示，若干子像素01的排列规律为：呈矩阵排列的若干像素单元组4；其中，
各像素单元组4包括：2行交错排列的子像素01，像素单元组4中每行包括3个颜色不同的子像素01，且下基板上任意彼此相邻的三个子像素01颜色不相同。
如图3a所示，各数据线02与位于该数据线02同一侧的子像素01对应连接。即，连接数据线02和子像素01的薄膜晶体管(TFT)均位于各子像素的同一侧；或
如图3b所示，各数据线02交替与位于该数据线02两侧的子像素01对应连接。即，奇数行的用于连接数据线和子像素的薄膜晶体管位于对应行子像素的一侧，偶数行的用于连接数据线和子像素的薄膜晶体管位于对应行子像素的另一侧。
进一步地，在本发明实施例提供的上述内嵌式触摸屏中，如图3a和图3b所示，3个不同颜色的子像素01分别为红色(R)子像素、绿色(G)子像素和蓝色(B)子像素。这样在显示时，以相邻的两个子像素为一像素，或以彼此相邻的三个子像素组成两个像素，每个像素“借”用与其相邻的像素的另一种颜色的子像素来构成三基色。即，每个像素和相邻的像素共享自己所不具备的那种颜色的子像素，共同达到白色显示。
例如，在上述内嵌式触摸屏中，为了降低制作难度，如图3a和图3b所示，导线04的延伸方向与数据线02的延伸方向相同。
本发明实施例提供的上述内嵌式触摸屏，由于每个像素只包括两个子像素或者两个像素包括三个子像素，因此，与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3甚至是1/2的子像素的数量。相应地，数据线的数量也可以减少1/3或者1/2。因此可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线。从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。
实例二：
本发明实施例提供的内嵌式触摸屏，如图4所示，若干子像素01的排列规律为：呈矩阵排列的若干像素单元组4；其中，
各像素单元组4包括：2列交错排列的子像素01，像素单元组4中每列包括3个颜色不同的子像素01，且下基板上任意彼此相邻的三个子像素01颜色不相同。
例如，各数据线02与位于该数据线02同一侧的子像素01对应连接。
进一步地，在上述内嵌式触摸屏中，如图4所示，栅线05位于相邻的奇数行子像素01和偶数行子像素01之间，且与位于该栅线05同一侧的子像素01电连接。
进一步地，在本发明实施例提供的上述内嵌式触摸屏中，如图4所示，3个不同颜色的子像素01分别为红色(R)子像素、绿色(G)子像素和蓝色(B)子像素。这样在显示时，以相邻的两个子像素为一像素，或以彼此相邻的三个子像素组成两个像素，每个像素“借”用与其相邻的像素的另一种颜色的子像素来构成三基色，即每个像素和相邻的像素共享自己所不具备的那种颜色的子像素，共同达到白色显示。
例如，在上述内嵌式触摸屏中，为了降低制作难度，如图4所示，导线04的延伸方向与数据线02的延伸方向相同。
本发明实施例提供的上述内嵌式触摸屏，由于每个像素只包括两个子像素或者两个像素包括三个子像素，因此，与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3甚至是1/2的子像素的数量。相应地，数据线的数量也可以减少1/3或者1/2。因此，可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线，从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。
实例三：
本发明实施例提供的上述内嵌式触摸屏，如图5a和图5b所示，若干子像素01的排列规律为：若干呈矩阵排列的像素单元组4；其中，
各像素单元组4包括：呈矩阵排列的4行子像素01，每行均包括3个颜色不同的子像素01；其中，第一行的排序为第一子像素、第二子像素和第三子像素；第二行的排序为第三子像素、第一子像素和第二子像素；第三行的 排序为第二子像素、第三子像素和第一子像素；第四行的排序为第三子像素、第一子像素和第二子像素。
例如，各数据线02与位于该数据线02同一侧的子像素01对应连接。
进一步地，在本发明实施例提供的上述内嵌式触摸屏中，如图5a和图5b所示，3个不同颜色的子像素01分别为红色(R)子像素、绿色(G)子像素和蓝色(B)子像素。这样在显示时，以相邻的两个子像素为一像素，每个像素“借”用与其相邻的像素的另一种颜色的子像素来构成三基色。即，每个像素和相邻的像素共享自己所不具备的那种颜色的子像素，共同达到白色显示。
进一步地，在实施时，第一子像素可以是红色子像素、绿色子像素和蓝色子像素中之一，同理，第二子像素和第三子像素也可以分别是红色子像素、绿色子像素和蓝色子像素中之一，只要保证第一子像素、第二子像素和第三子像素的颜色不同即可，在此不作限定。
例如，在上述内嵌式触摸屏中，为了降低制作难度，如图5a所示，导线04的延伸方向与数据线02的延伸方向相同。
或者，在实施时，为了保证显示屏中同一颜色的子像素的开口率一致，如图5b所示，在上述内嵌式触摸屏中，导线04沿列方向延伸，且位于导线04左侧或右侧的子像素01的颜色相同。
进一步地，在实施时，如图5b所示，当导线沿同一颜色的子像素的延伸方向延伸时，为了避免导线与数据线接触，在导线与数据线交叠的位置，导线采用透明导电材料进行跳线连接。
本发明实施例提供的上述内嵌式触摸屏，由于每个像素只包括两个子像素，因此与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3子像素的数量。相应地，数据线的数量也可以减少1/3。因此，可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线。从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。
实例四：
本发明实施例提供的上述内嵌式触摸屏，如图6所示若干子像素01的排列规律为：呈矩阵排列的若干像素单元组4；其中，
各像素单元组4包括：矩阵排列的n行子像素01和n列子像素01，像素单元组4中每行和每列均包括n种颜色不同的子像素01，且沿着像素单元组04的每条对角线方向的子像素01包括n种子像素01中的至少两种，其中n为大于且等于3的正整数。
例如，各数据线02与位于该数据线02同一侧的子像素01对应连接。
例如，在本发明实施例提供的上述内嵌式触摸屏中，如图6所示，n等于4，4种颜色不同的子像素分别为红色(R)子像素、绿色(G)子像素和蓝色(B)子像素和白色(W)子像素。这样在显示时，以相邻的两个子像素为一像素，每个像素“借”用与其相邻的像素的另一种颜色的子像素来构成三基色。即，每个像素和相邻的像素共享自己所不具备的那种颜色的子像素，共同达到白色显示。
例如，在上述内嵌式触摸屏中，为了降低制作难度，如图6所示，导线04的延伸方向与数据线02的延伸方向相同。
本发明实施例提供的上述内嵌式触摸屏，由于每个像素只包括两个子像素，因此与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3子像素的数量。相应地，数据线的数量也可以减少1/3。因此，可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线。从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。
一般地，触摸屏的密度通常在毫米级。因此，在实施时，可以根据所需的触控密度选择各自电容电极的密度和所占面积以保证所需的触控密度，通常各自电容电极设计为5mm*5mm左右的方形电极。而显示屏的密度通常在微米级。因此，一般一个自电容电极会对应显示屏中的多个子像素。
例如，由于本发明实施例提供的上述触摸屏可采用公共电极层复用作为自电容电极，在采用公共电极层复用作为自电容电极的情况下，为了减少显示和触控信号之间的相互干扰，在实施时，需要采用触控和显示阶段分时驱动的方式。
例如，例如，如图7a和图7b所示的驱动时序图中，将触摸屏显示每一帧(V-sync)的时间分成显示时间段(Display)和触控时间段(Touch)。例如，如图7a和图7b所示的驱动时序图中，触摸屏的显示一帧的时间为16.7ms， 可选取其中5ms作为触控时间段，其他的11.7ms作为显示时间段。当然也可以根据IC芯片的处理能力适当的调整两者的时长，在此不做具体限定。在显示时间段(Display)，对触摸屏中的每条栅极信号线Gate1，Gate2……Gaten依次施加栅扫描信号，对数据信号线Data施加灰阶信号，与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cxn分别施加公共电极信号，以实现液晶显示功能。在触控时间段(Touch)，如图7b所示，与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cxn同时施加驱动信号，同时接收各自电容电极Cx1……Cxn的反馈信号。也可以如图7a所示，与各自电容电极Cx1……Cxn连接的触控侦测芯片向各自电容电极Cx1……Cxn依次施加驱动信号，分别接收各自电容电极Cx1……Cxn的反馈信号，在此不做限定，通过对反馈信号的分析判断是否发生触控，以实现触控功能。
基于同一发明构思，本发明实施例还提供一种显示装置，包括本发明实施例提供的上述任一内嵌式触摸屏。
例如，该显示装置包括液晶显示屏和有机电致发光显示屏中的任意一种。
例如，该显示装置可以为液晶显示器、电子纸、OLED(Organic Light-Emitting Diode，有机发光二极管)显示器等显示器件以及包括这些显示器件的手机、手表、平板电脑、电视机、平板电脑、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。该显示装置的实施可以参见上述内嵌式触摸屏的实施例，重复之处不再赘述。
本发明实施例提供的一种内嵌式触摸屏及显示装置，由于每个像素只包括两个子像素或者两个像素包括三个子像素。因此与通常一个像素包括三个子像素或者四个子像素相比，在实现相同像素的情况下可以减少1/3甚至是1/2的子像素的数量。相应地，数据线的数量也可以减少1/3或者1/2。因此可以将驱动芯片原用于减少的那部分数据线的通道现用于与自电容电极连接的导线。从而在不增加驱动芯片通道的基础上就可以实现触控和显示的集成，进而降低内嵌式触摸屏的成本。并且，导线是与数据线同层设置的情况下，可以在现有制备工艺的基础上，与数据线通过一次构图工艺形成，不需要增加额外的工艺单独制备导线，从而进一步节省生产成本，提高生产效率。
以上所述，仅为本发明的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
