Description

触摸式三维光栅及显示装置 技术领域
本发明的实施例涉及一种触摸式三维光栅及显示装置。
背景技术
三维显示技术的最基本的原理是使人的左右眼分别接收不同的画面，然后经过大脑对图像信息进行叠加重生，从而产生立体效果。
三维显示技术分为裸眼式和眼镜式，而常见的裸眼式三维显示装置的结构是在显示屏上增加一层三维光栅，三维光栅按照实现方式一般分为柱状透镜光栅和狭缝光栅(屏障栅栏)，两者都可利用液晶光栅实现。例如，如图1所示的液晶光栅一般包括：上偏光片1、下偏光片2、上基板3、下基板4、以及在两个基板之间的液晶层5，其中下基板4和上基板3上分别形成有板状电极7和条状电极6。
示例性地，该液晶光栅作为屏障栅栏时的工作原理如下：
当条状电极6与板状电极7之间存在电位差而产生电场时，与条状电极6对应的液晶分子发生旋转，其他液晶分子保持原来取向，不发生旋转。此时，光线从下偏光片2进入，与下偏光片2的透过轴平行的偏振光进入到液晶层5，偏振光通过发生旋转的液晶分子时会逐步改变振动方向，到达上偏光片1时偏振光的振动方向与上偏光片1的透过轴不一致，则光线不通过，由此，在与条状电极6对应的区域形成了遮光的暗条纹；而偏振光通过未发生旋转的液晶分子时不会改变振动方向，到达上偏光片1时偏振光的振动方向和上偏光片1的透过轴一致，则光线通过，由此在不与条状电极对应的区域形成了透光的明条纹，这样形成了具有明暗相间条纹的狭缝光栅，从而实现了光栅式三维显示模式。在三维显示模式下，狭缝光栅使得左眼像素发出的光只射入左眼，右眼像素发出的光只进入右眼，通过将左右眼图像分开，实现了三维显示效果。
目前，随着触控技术的发展，出现了集成有触摸功能和三维显示功能的3D显示装置，这需要在三维光栅上增加一层触控板，这种结构及其生产工艺 相对复杂，贴合对位精度要求高，会增加模组整体的制作成本，同时由于需要额外增加一层触控板会大大增加显示装置的厚度。
发明内容
本发明的实施例提供了一种触摸式三维光栅及显示装置，该触摸式三维光栅的结构简单且能同时实现触控功能与三维显示功能，且具有该触摸式三维光栅的显示装置具有简单的模组结构且生产工艺简单，且制作成本被降低以及模组厚度被减小。
一方面，本发明的实施例提供的一种触摸式三维光栅，包括：相对而置的上基板和下基板；多个第一条状电极，设置于所述下基板面向所述上基板的一侧；多个第二条状电极，与所述多个第一条状电极交叉设置于所述上基板面向所述下基板的一侧，其中在触控时间段，将两两之间间隔一个所述第一条状电极的多个所述第一条状电极作为触控驱动电极，将两两之间间隔一个所述第二条状电极的多个所述第二条状电极作为触控感应电极；在三维显示时间段，将两两之间间隔一个所述第一条状电极的多个所述第一条状电极作为第一三维驱动电极，将所述多个第二条状电极的全体作为另一三维驱动电极；或，将两两之间间隔一个所述第二条状电极的多个所述第二条状电极作为第二三维驱动电极，将所述多个第一条状电极的全体作为另一三维驱动电极。
另一方面，本发明的实施例提供了一种显示装置，包括：显示面板；以及如上所述的触摸式三维光栅，设置在所述显示面板出光侧。

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。
下面结合附图，对本发明实施例提供的触摸式三维光栅及显示装置进行详细说明。
附图中各层薄膜厚度和大小形状不反映触摸式三维光栅的真实比例，目的只是示意说明本发明实施例的内容。
本发明实施例提供的触摸式三维光栅，如图2所示，包括：相对而置的上基板01和下基板02，位于下基板02面向上基板01一侧的多个第一条状电极03，位于上基板01面向下基板02一侧且与第一条状电极03交叉而置的多个第二条状电极04。
如图3和图4所示，在触控时间段，将两两之间间隔一个第一条状电极的多个第一条状电极作为触控驱动电极031，将两两之间间隔一个第二条状电极的多个第二条状电极作为触控感应电极041。
如图3和图4所示，在三维显示时间段，将两两之间间隔一个第一条状电极的多个第一条状电极作为第一三维驱动电极032，将多个第二条状电极04的全体作为另一三维驱动电极，这里多个第二条状电极04的全体视作为面状电极；或，将两两之间间隔一个第二条状电极的多个第二电极04作为第二三维驱动电极042，将多个第一条状电极的全体作为另一三维驱动电极， 这里多个第一条状电极的全体视作为面状电极。
本发明实施例提供的一种触摸式三维光栅，将设置于下基板的板状电极变换为条状电极，使上基板和下基板相对的一面分别具有交叉而置的第一条状电极03和第二条状电极04。在触控时间段，将两两之间间隔一个第一条状电极的多个第一条状电极03作为触控驱动电极031，将两两之间间隔一个第二条状电极的多个第二条状电极04作为触控感应电极041，以实现触控功能；在三维显示时间段，将两两之间间隔一个第一条状电极的多个第一条状电极03作为第一三维驱动电极032，将多个第二条状电极04的全体作为面状电极；或，将两两之间间隔一个第二条状电极的多个第二条状电极04作为第二三维驱动电极042，将多个第一条状电极03的全体作为面状电极；第一三维驱动电极032或第二三维驱动电极042都能与面状电极形成三维光栅结构，即能够在与第一三维驱动电极032的延伸方向垂直的方向或在与第二三维驱动电极042的延伸方向垂直的方向形成三维光栅结构，从而实现双方向的三维显示模式。相对于在三维光栅上增加一层触控板的结构，本发明实施例提供的触控式三维光栅仅改变了下基板的电极结构，便可分时实现触控功能和双方向三维显示功能，从而简化了模组结构以及生产工艺，降低了模组整体的制作成本同时降低了显示装置的厚度。
应该注意的是，在本发明的实施例中，作为触控驱动电极的两两之间间隔一个第一条状电极的多个第一条状电极在三维显示时间段也可以作为第一三维驱动电极，作为触控感应电极的两两之间间隔一个第二条状电极的多个第二条状电极在三维显示时间段也可以作为第二三维驱动电极，对应地，将多个第二条状电极或多个第一条状电极的全体作为另一三维驱动电极。或者，在触控时间段作为触控驱动电极的多个第一条状电极和在三维显示时间段作为第一三维驱动电极的多个第一条状电极是不同的条状电极，二者组合起来是多个第一条状电极的全体；在触控时间段作为触控感应电极的多个第二条状电极和在三维显示时间段作为第二三维驱动电极的多个第二条状电极是不同的条状电极，二者组合起来是多个第二条状电极的全体。本发明的实施例并不对此进行限定。
示例性地，本发明实施例提供的上述触摸式三维光栅中在上基板01上设置的第二条状电极04和在下基板02上设置的第一条状电极03一般采用相互 异面垂直的关系，在以下对本发明实施例提供的触摸式三维光栅的说明中，都是以第一条状电极03和第二条状电极04相互异面垂直为例进行说明，并以图3所示的第一条状电极03为横向电极，对应地，以图4所示的第二条状电极04为纵向电极为例进行说明。
示例性地，在本发明实施例提供的上述触摸式三维光栅中，位于下基板02的第一条状电极03分时驱动，在触控时间段，选取两两之间间隔一个第一条状电极的多个第一条状电极03作为触控驱动电极031，即，隔一条第一条状电极03选取一条第一条状电极03作为触控驱动电极031以在触控时间段加载触控驱动信号，而其他第一条状电极03则作为浮空电极以屏蔽触控驱动电极031之间信号的相互干扰；在三维显示时间段，可以选取两两之间间隔一个第一条状电极的多个第一条状电极03作为第一三维驱动电极032，多个第二条状电极04的全体作为另一三维驱动电极，这里，多个第二条状电极04的全体可以视为面状电极，在三维显示时间段通过向第一三维驱动电极032和面状电极加载三维驱动信号而产生电场，从而在对应于第一三维驱动电极032的区域处形成遮光的暗条纹，而在其他区域处则形成透光的明条纹；或者，在三维显示时间段内，通过向第一三维驱动电极032和多个第二条状电极04的全体构成的面状电极加载驱动信号而产生电场，从而形成柱状透镜结构。当然，在三维显示时间段，也可以将多个第一条状电极03的全部当成面状电极，而对应地，两两之间间隔一个第二条状电极的多个第二条状电极可以作为第二三维驱动电极。
可以看出在两个时间段内各第一条状电极03的工作互不干扰，因此，触控驱动电极031和第一三维驱动电极032可以为相同的第一条状电极03，这样，相同的第一条状电极03在触控时间段加载触控驱动信号，在三维显示时间段加载相同的三维驱动信号以实现视差挡板中的暗条纹，或加载不同的三维驱动信号以实现柱状透镜结构，或均接地。或者，触控驱动电极031和第一三维驱动电极032可以彼此交替设置的第一条状电极03，如图3所示，这样，在触控时间段触控驱动电极031被加载触控驱动信号，第一三维驱动电极032作为浮空电极，在三维显示时间段对第一三维驱动电极032加载相同的三维驱动信号以实现视差挡板中的暗条纹，或加载不同的三维驱动信号以实现柱状透镜结构，或接地，同时触控驱动电极031也接地。
示例性地，触摸结构的电极密度通常在毫米级，而三维光栅的电极密度通常在微米级，显然三维光栅的电极密度远大于触控结构的电极密度，因此，可以将相邻的几个触控驱动电极031作为一个触控驱动总电极，即如图3所示，将每相邻的至少两个触控驱动电极031在另一端通过导线033相互连接，之后可以连接金属走线034以便通过金属走线034在不同时间段加载不同的信号，例如在触控时间段可以向各触控驱动总电极加载触控驱动信号；在三维显示阶段，若采用触控驱动电极031作为第一三维驱动电极032，可以向各触控驱动总电极加载相同的三维驱动信号，以便形成遮光的暗条纹，若采用相邻触控驱动电极031之间的第一条状电极03作为第一三维驱动电极032，或采用包括触控驱动电极031的第一条状电极03作为面状电极，可以将各触控驱动总电极接地。示例性地，金属走线034可以和导线033以及第一条状电极03同层同材质。
进一步地，从上述实现视差挡板式三维显示和触控功能的过程中，可以看出，除触控驱动电极031之外的各第一条状电极03，不论是触控时间段还是三维显示时间段，执行的功能相同，例如在触控时间段，除触控驱动电极031之外的各第一条状电极03作为浮空电极不加载信号，在三维显示时间段，除触控驱动电极031之外的各第一条状电极03若作为第一三维驱动电极032则加载相同的三维驱动信号，以实现遮光的暗条纹，如果不作为三维驱动电极则接地，以实现透光的明条纹。因此，为了方便向除触控驱动电极031之外的第一条状电极03加载对应的信号，如图3所示，可以将其在另一端通过导线033相互连接；指的注意的是，该另一端是指与触控驱动电极031与金属走线034连接的一端相反的另一端。
同理，示例性地，在本发明实施例提供的上述触摸式三维光栅中，位于上基板01的第二条状电极04分时驱动，在触控时间段，选取两两之间间隔一个第二条状电极的多个第二条状电极04作为触控感应电极041，即隔一条第二条状电极04选取一条第二条状电极04作为触控感应电极041以在触控时间段耦合触控驱动信号并输出，而其他第二条状电极04则作为浮空电极以屏蔽触控感应电极041之间信号的相互干扰；在三维显示时间段，可以选取两两之间间隔一个第二条状电极的多个第二条状电极04作为第二三维驱动电极042，在三维显示时间段加载三维驱动信号与多个第一条状电极03的全 体构成的面状电极产生电场，以明显相间的条纹；或者，第二三维驱动电极042在三维显示时间段加载三维驱动信号与多个第一条状电极03的全体构成的面状电极产生电场，而形成柱状透镜结构。当然也可以将多个第二条状电极04的全体当成面状电极，示例性地，面状电极接地。
可以看出在两个时间段内各第二条状电极04的工作互不干扰，因此，触控感应电极041和第二三维驱动电极042可以为相同的第二条状电极04，这样，相同的第二条状电极04在触控时间段耦合触控驱动信号并输出，在三维显示时间段加载相同的三维驱动信号以实现狭缝光栅，或加载不同的三维驱动信号以实现柱状透镜结构，或均接地。或者，触控感应电极041和第二三维驱动电极042可以为不同的第二条状电极04，如图4所示，这样，在触控时间段触控感应电极041耦合触控驱动信号并输出，第二三维驱动电极042作为浮空电极，在三维显示时间段对第二三维驱动电极042加载相同的三维驱动信号以实现狭缝光栅，或加载不同的三维驱动信号以实现柱状透镜结构，或接地，同时触控驱动电极031接地。
示例性地，触摸结构的电极密度通常在毫米级，而三维光栅的电极密度通常在微米级，显然三维光栅的电极密度远大于触控结构的电极密度，因此，示例性地，可以将相邻的几个触控感应电极041作为一个触控感应总电极，如图4所示，将每相邻的至少两个触控感应电极041在另一端通过导线043相互连接，之后可以连接金属走线044以便通过金属走线044在不同时间段加载不同的信号，例如在触控时间段可以各触控感应总电极耦合触控驱动信号并输出；在三维显示阶段，若采用触控感应电极041作为第二三维驱动电极042时，可以向各触控感应总电极加载相同的三维驱动信号，以便形成遮光的暗条纹，若采用相邻触控感应电极041之间的第二条状电极04作为第二三维驱动电极042，或采用包括触控感应电极041的第二条状电极04作为面状电极时，可以将各触控感应总电极接地。示例性地，金属走线044可以和导线043以及第二条状电极04同层同材质。
进一步地，从上述实现视差挡板式三维显示和触控功能的过程中，可以看出，除触控感应电极041之外的各第二条状电极04，不论是触控时间段还是三维显示时间段，执行的功能相同，例如在触控时间段，除触控感应电极041之外的各第二条状电极04作为浮空电极不加载信号，在三维显示时间段， 除触控感应电极041之外的各第二条状电极04若作为第二三维驱动电极042则加载相同的三维驱动信号，以实现遮光的暗条纹，反之则接地，以实现透光的明条纹。因此，为了方便向除触控感应电极041之外的第二条状电极04加载对应的信号，如图4所示，可以将其在另一端通过导线043相互连接；应该注意的是，该另一端是指与触控感应电极041与金属走线044连接的一端相反的另一端。
示例性地，本发明实施例提供的上述触摸式三维光栅在三维显示模式，可以实现柱状透镜光栅和狭缝光栅(屏障栅栏)。示例性地，在实现狭缝光栅时，可以采用在上基板01和下基板02之间设置液晶层或电致变色材料层实现。例如，在三维显示时间段，对各第一三维驱动电极032施加相同的三维驱动信号，各第二条状电极04接地，使液晶层或电致变色材料层中与第一三维驱动电极032对应的区域形成如图5所示的横向的遮光区域；或，对第二三维驱动电极042施加相同的三维驱动信号，各第一条状电极03接地，使液晶层或电致变色材料层中与第二三维驱动电极042对应的区域形成如图6所示的纵向的遮光区域。
示例性地，本发明实施例提供的上述触摸式三维光栅在三维显示模式，在实现狭缝光栅时，在三维显示时间段，为了实现透光的明条纹，如图5所示，除第一三维驱动电极032以外的第一条状电极03接地；或，如图6所示，除第二三维驱动电极042以外的第二条状电极04接地。
图5和图6是以触控驱动电极031和第一三维驱动电极032为交替设置的第一条状电极03，触控感应电极041和第二三维驱动电极042为交替设置的第二条状电极04为例进行说明的。基于此，在触控时间段，第一三维驱动电极032和第二三维驱动电极042均设置为浮空电极，因此，在触控时间段工作电极的平面图如图7所示。
图8示出了图6所示结构的三维光栅的电路时序图，三维光栅采用分时驱动的方式，在触控时间段(Touch)，触控驱动电极Tx1……Txn加载触控驱动信号，触控感应电极Rx1……Rxn耦合触控驱动信号并输出，第一三维驱动电极032和第二三维驱动电极042作为浮空电极不输入信号；在三维显示时间段(3D display)，触控驱动电极Tx1……Txn和触控感应电极Rx1……Rxn接地(GND)，第一三维驱动电极032加载三维驱动信号DC-Vcom， 第二三维驱动电极042接地(GND)。
示例性地，本发明实施例提供的上述触摸式三维光栅在实现柱状透镜光栅时，可以采用在上基板01和下基板02之间设置液晶层实现。例如，在三维显示时间段，对相邻的第一三维驱动电极032施加不同的三维显示信号，各第二条状电极04接地，使液晶层中的液晶分子发生偏转形成多个横向的柱状透镜结构；或，对相邻的第二三维驱动电极042施加不同的三维显示信号，各第一条状电极03接地，使液晶层中的液晶分子发生偏转形成多个纵向的柱状透镜结构。
基于同一发明构思，本发明实施例还提供了一种显示装置，包括显示面板，以及设置于显示面板出光侧的触摸式三维光栅，该触摸式三维光栅为本发明实施例提供的上述触摸式三维光栅。该显示装置可以为：手机、平板电脑、电视机、显示器、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触摸式三维光栅的实施例，重复之处不再赘述。
示例性地，该显示装置中的显示面板可以为显示面板为液晶(LCD)显示面板、有机电致发光(OLED)显示面板、等离子体(PDP)显示面板、或阴极射线(CRT)显示器等，在此不做限定。
本发明实施例提供的上述触摸式三维光栅及显示装置，将设置于下基板的板状电极改变为条状电极，使上基板和下基板相对的一面分别具有交叉而置的第一条状电极和第二条状电极，在触控时间段，将两两之间间隔一个第一条状电极的多个第一条状电极作为触控驱动电极，将两两之间间隔一个第二条状电极的多个第二条状电极作为触控感应电极，以实现触控功能；在三维显示时间段，将两两之间间隔一个第一条状电极的多个第一条状电极作为第一三维驱动电极，将多个第二条状电极的全体作为另一三维驱动电极，这里多个第二条状电极的全体视作为面状电极；或，将两两之间间隔一个第二条状电极的多个第二条状电极作为第二三维驱动电极，将多个第一条状电极的全体作为另一三维驱动电极，这里多个第一条状电极的全体视作为面状电极；第一三维驱动电极或第二三维驱动电极都能与面状电极形成三维光栅结构，即能够在与第一三维驱动电极的延伸方向垂直的方向或在与第二三维驱动电极的延伸方向垂直的方向形成三维光栅结构，从而实现双方向的三维显 示模式。相对于在三维光栅上增加一层触控板的结构，本发明实施例提供的触控式三维光栅仅改变了下基板的电极结构，便可分时实现触控功能和双方向三维显示功能，简化了模组结构以及生产工艺，降低了模组整体的制作成本同时降低了显示屏的厚度。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
本申请要求于2014年7月8日递交的中国专利申请第201410323376.6号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
