Description

触摸式棵眼 3D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棵眼 3D光栅及显示装置。 背景技术
随着液晶显示技术的不断发展， 目前三维（ 3D )显示技术已经备受关注。 三维显示技术的最基本的原理之一是利用左右人眼分别接收不同画面， 然后 经过大脑对这些不同画面的图像信息进行叠加重生， 得到立体效果的影像。
为了实现三维显示，可在显示屏上增加一层棵眼 3D光栅。棵眼 3D光栅 按照实现方式一般分为柱透镜光栅和狭缝光栅，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是由上偏光片 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组成。 上基板 3和下基板 4分别具 有板状电极 6和条状电极 7 , 条状电极 7的多个电极条彼此平行排布。 该液 晶光栅的工作原理如下。
当条状电极 7与板状电极 6之间存在电位差而产生电场时， 与条状电极 7对应的液晶分子发生旋转， 其他液晶分子保持原来形状， 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 振片 1时偏振光的振动方向变得与上偏振片 1的透过轴不一致， 则这些振动 方向改变的光线不通过上偏振片 1 , 从而在与条状电极 7对应的区域形成了 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 偏振片 1时偏振光的振动方向和上偏振片 1的透过轴一致， 则这些振动方向 未改变的光线可通过上偏振片 1 ,在与非条状电极对应的区域形成了明条纹。 这样就形成了沿条状电极长度延伸方向的视差光栅， 实现了光栅式三维显示 模式。 在 3D模式下， 视差光栅控制来使得对应左眼图像的像素发出的光只 射入左眼， 对应右眼图像的像素发出的光只进入右眼， 这就可以使得左右眼 所看到的画面彼此不同， 实现三维显示效果。
目前， 随着触控屏幕技术的发展， 出现了将触摸屏和三维显示相结合的 3D显示装置，其结构是在三维显示屏上再增加一层触控基板。这种结构及其 生产工艺相对复杂， 会增加模组整体的制作成本， 同时由于需要额外增加一 层触控基板会大大增加显示屏的厚度。 发明内容

本发明的一个实施例提供的一种触摸式棵眼 3D光栅， 如图 2所示， 其 包括： 上基板 01 , 与上基板 01相对设置的下基板 02,设置于下基板 02面向 上基板 01一侧的条状电极 04, 以及设置于上基板 01面向下基板 02一侧的 板状电极 05。 条状电极 04包括多条彼此平行且以一定间距（狭缝） 间隔开 的电极条， 图 2中示出了这些电极条的横截面示意图。
该触摸式棵眼 3D光栅还包括： 设置于上基板 01与板状电极 05之间触 控电极结构 06, 该触控电极结构 06与板状电极 05相互绝缘。
触控电极结构 06的一个示例， 如图 3所示， 包括： 呈交叉排列且相互绝 缘的多条第一触控感测线 061和多条第二触控感测线 062, 以及位于相邻两 条第一触控感测线 061与相邻两条第二触控感测线 062所限定区域内的触控 电极 063; 各触控电极 063分别与相邻的一条第一触控感测线 061 以及相邻 的一条第二触控感测线 062电性相连。
本实施例提供的上述棵眼 3D光栅可以是狭缝光栅， 也可以是柱透镜光 栅， 这两种光栅都可利用液晶光栅实现。 下面的描述都以液晶光栅为例， 即 如图 2所示，在上基板 01和下基板 02之间设置液晶层 03为例进行说明。 当 此不做赞述。
本实施例提供的上述棵眼 3D光栅，可以通过在现有的棵眼 3D光栅中增 加与板状电极 05绝缘的触控电极结构 06得到。该触控电极结构 06中的各触 控电极 063与板状电极 05形成电容体。 当手指触摸该棵眼 3D光栅或在棵眼 3D光栅的表面移动时，手指和触控电极 063也形成电容体，手指和触控电极 063形成的电容体会使触控电极 063的带电量发生变化。 通过检测与触控电 极电性相连的第一触控感测线 061和第二触控感测线 062上的信号变化， 就 可以判断出触摸点的位置， 实现触控功能。 相对于在三维显示屏上增加一层 触控基板的结构， 本实施例提供的棵眼 3D光栅仅需在内部在上基板增加触 控电极结构， 由此筒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。
而且， 在本实施例提供的棵眼 3D光栅中， 各条状电极 04之间一般具有 均匀的缝隙。 当对条状电极 04和板状电极 05分别施加电压， 在两者之间产 生电位差而产生电场时， 与条状电极 04对应的 （例如图 2中条状电极 04正 上方的）液晶层 03中的液晶分子发生旋转，与狭缝对应的其他液晶分子保持 原来形状而不发生旋转。在与条状电极 04对应的区域形成暗条纹，与非条状 电极对应的区域（狭缝区域）形成了明条纹， 这样形成了沿条状电极 04的长 度延伸方向的视差光栅。 该视差光栅控制使得对应左眼图像的像素发出的光 只射入左眼， 对应右眼图像的像素发出的光只进入右眼， 从而可以使得左右 目艮所看到的画面彼此不同， 实现三维显示效果。
下面对本实施例提供的上述棵眼 3D光栅中的触控电极结构进行详细的 说明。
较佳地，例如，在触控电极结构 06中的第一触控感测线 061与第二触控 感测线 062的延伸方向一般相互垂直， 且两者相互绝缘。 例如在如图 3所示 的结构中， 第一触控感测线 061沿着垂直方向延伸， 第二触控感测线 062沿 着水平方向延伸， 在触控电极 063上的电量发生变化时通过检测第一触控感 测线 061上的信号变化， 可以确定触摸点的 X轴坐标， 通过检测第二触控感 测线 062上的信号变化， 可以确定触摸点的 y轴坐标， 从而定位触摸点的位 置。
较佳地， 为了保证在整个棵眼 3D光栅上触控精度的均一性， 一般将任 意相邻的两条第一触控感测线 061之间的间隔设置为相同； 将任意相邻的两 条第二触控感测线 062之间的间隔设置为相同。
各触控电极 063与第一触控感测线 061和第二触控感测线 062的连接关 系， 可以如图 3所示， 为——对应关系， 即一个触控电极 063与相邻的一条 第一触控感测线 061以及一条第二触控感测线 062电性相连。 这样当在该触 控电极 063处发生触摸时， 仅与其相连的一条第一触控感测线 061和一条第 二触控感测线 062上的信号发生变化， 可以准确定位触摸点的位置。
例如， 各第一触控感测线 061和各第二触控感测线 062可以和触控电极 063直接电性相连，也可以如图 4所示的示例，通过导线 064与触控电极 063 相连， 在此不做限定。
例如，可以将触控电极结构 06中的第一触控感测线 061与第二触控感测 线 062同层设置，并且在两者的交叉处一般通过桥接结构保证两者相互绝缘。 更具体地， 可以将各第一触控感测线 061在与各第二触控感测线 062的交叉 处设置桥接结构，或可以将各第二触控感测线 062在与各第一触控感测线 061 的交叉处设置桥接结构 065 , 如图 5所示， 在此不作限定。 例如， 也可以将 触控电极结构 06中的第一触控感测线 061与第二触控感测线 062不同层设 置， 且彼此绝缘。
在将第一触控感测线 061与第二触控感测线 062同层设置时， 可以将各 第一触控感测线 061和各第二触控感测线 062设置于触控电极 063与板状电 极 05之间，也可以将各第一触控感测线 061和各第二触控感测线 062设置于 触控电极 063与上基板 01之间， 在此不作限定。
或者，例如，可以将触控电极结构 06中的第一触控感测线 061与第二触 控感测线 062分别设置在触控电极 063的两侧。 例如， 可以将各第一触控感 测线 061设置于触控电极 063与板状电极 05之间，将各第二触控感测线 062 设置于触控电极 063与上基板 01之间；或将各第一触控感测线 061设置于触 控电极 063与上基板 01之间，将各第二触控感测线 062设置于触控电极 063 与板状电极 05之间， 在此不做限定。 基于同一发明构思， 本发明的一个实施例还提供了一种显示装置， 如图
6所示， 其包括显示面板 100和位于显示面板出光侧的触摸式棵眼 3D光栅 200,该触摸式棵眼 3D光栅为本发明实施例提供的上述触摸式棵眼 3D光栅。 该显示装置的实施可以参见上述触摸式棵眼 3D光栅的实施例， 重复之处不 再赘述。
例如， 该显示装置中的显示面板可以为液晶显示（LCD ) 面板、 有机电 致发光显示 （OLED ) 面板、 等离子体（PDP ) 面板、 或阴极射线管 （CRT ) 显示器等， 在此不做限定。
本发明实施例提供的一种触摸式棵眼 3D光栅及显示装置，在棵眼 3D光 栅内部增加位于上基板与板状电极之间的触控电极结构； 该触控电极结构包 括呈交叉排列且相互绝缘的多条第一触控感测线和多条第二触控感测线， 位 于相邻两条第一触控感测线与相邻两条第二触控感测线所限定区域内的触控 电极， 各触控电极与板状电极形成电容体。 在发生触摸时， 人体电场使触控 电极上的带电量发生变化。 通过检测与触控电极电性相连的第一触控感测线 和第二触控感测线上的信号变化， 实现触控功能。 相对于在三维显示屏上增 加一层触控基板的结构， 本发明的实施例仅在上基板增加触控电极结构， 筒 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。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
