为使显示装置具有可调视角的功能， 本发明的实施例提供了一种电致变 色面板及显示装置， 利用电致变色材料在外加电场的作用下产生稳定的、 可 逆的颜色变化的现象， 即表现为透光和不透光的特性， 将电致变色面板置于 显示面板前方， 通过控制电致变色面板中电极块的通电状态， 即可使得显示 装置具有可调视角的功能。
为了使本领域技术人员更好的理解本发明实施例的技术方案， 下面结合 说明书附图对本发明实施例进行详细的描述。
如图 1所示， 为本发明实施例提供的一种电致变色面板的结构示意图。 该电致变色面板包括： 对盒的第一基板 10和第二基板 20, 位于第一基板 10 和第二基板 20之间的电致变色层 30, 其中， 第一基板 10具有由多个电极块 11组成的第一透明电极层， 第二基板 20具有与第一透明电极层相对设置的 第二透明电极层。
在本实施例中， 电致变色面板利用电致变色材料在外加电场的作用下产 生稳定的、 可逆的颜色变化的现象， 即表现为透光和不透光的特性， 也就是 说， 电致变色层 30的颜色、透光性或透明性由第一透明电极层与第二透明电 极层之间的电场控制。 例如， 在第一基板 10上的第一透明电极层中， 多个电 极块 11分别与一组电压驱动线（图中未画出）电连接， 当未对第一透明电极 层中的各个电极块 11 和第二透明电极层施加电压时， 电致变色层 30表现为 透明态， 因此电致变色面板也为透明态， 不会影响光线的透过； 当对第一透 明电极层的电极块 11和第二透明电极层施加电压时， 电致变色层 30上与通 电的电极块对应的区域变为非透明态， 阻挡光透过。 因此， 将本发明实施例 提供的电致变色面板设置在显示面板的前方， 通过控制电致变色面板中电极 块的通电状态， 即可改变显示面板的视角， 从而使得显示装置具有可调视角 功能。
对电致变色面板中电极块通电状态的控制可以通过单独的控制电路实 现， 也可以与显示面板共用一个控制电路来实现， 其为本领域技术人员所熟 知， 这里不再详细描述。
为了有选择地改变电致变色面板的变色区域， 进而有选择地改变显示装 置的视角，在具体实施时，可以通过改变多个电极块 11的形状和在第一基板 10上的排列方式来实现。
如图 2所示， 为图 1中多个电极块在第一基板上的第一种排布图。 在图 2中， 每个电极块 11为矩形环状电极块， 且多个矩形环状电极块按照矩形环 的面积大小依次套设， 也就是说， 多个电极块 11分别为矩形环状电极块， 并 才艮据矩形环的面积大小， 面积大的矩形环状电极块套在面积小的矩形环状电 极块外侧。 例如， 多个矩形环为相似矩形环， 且多个矩形环状电极块按照矩 形环的面积大小依次等间距套设， 即多个电极块 11分别为矩形环状电极块， 且矩形环的形状相似， 并按照面积的大小等间距套设。 如此设置， 可以根据 需要对其中一个或几个电极块 11施加电压， 这些施加有电压的电极块 11与 第二透明电极层形成电场，从而使电致变色层 30与这些施加有电压的电极块 11对应的区域变色， 阻挡光线透过； 电致变色层 30与余下没有施加电压的 电极块 11对应的区域不变色， 即不影响光的透过。 多个电极块 11以上述方 式排布， 适用于阻挡显示装置四周光线射出， 从而使从显示装置的四周不能 看见显示装置显示的图像。
在上述实施例中， 多个电极块 11为矩形环状，但不限于此， 多个电极块 11也可以为其它形状， 例如， 每个电极块 11为长条形电极块， 通过组合这 些电极块 11的排列方式也可以达到有选择地控制电致变色面板变色的目的。
如图 3所示， 为图 1中多个电极块在第一基板上的第二种排布图。 在图 3中， 由若干个长条形电极块 11构成一个类矩形环， 多个长条形电极块可以 构成多个类矩形环，且这些类似矩形环按照面积的大小依次套设，也就是说， 将多个电极块 11分为若干组,每一组中的长条形电极块构成首尾相连或间断 的类矩形环， 这些类矩形环按照矩形环的面积大小依次套设， 例如， 每四个 所述长条形电极块构成一个类矩形环， 且多个类矩形环按照类矩形环的面积 大小等间距依次套设。 如此设置， 可以根据需要对其中一个或几个电极块 11 施加电压，这些施加有电压的电极块 11与第二透明电极层形成电场，从而使 电致变色层 30与这些施加有电压的电极块 11对应的区域变色， 阻挡光线透 过； 电致变色层 30与余下没有施加电压的电极块 11对应的区域不变色， 即 不影响光的透过。多个电极块 11以上述方式排布，适用于阻挡显示装置四周 光线射出， 从而使从显示装置的四周不能看见显示装置显示的图像。
如图 4所示， 为图 1中多个电极块在第一基板上的第三种排布图。 在图 4中， 每个电极块 11为长条形电极块， 且多个长条形电极块等间距排列成多 行。如此设置， 可以根据需要对其中一个或几个电极块 11施加电压， 这些施 加有电压的电极块 11与第二透明电极层形成电场， 从而使电致变色层 30与 这些施加有电压的电极块 11 对应的区域变色， 阻挡光线透过； 电致变色层 30与余下没有施加电压的电极块 11对应的区域不变色， 即不影响光的透过。 多个电极块 11以等间距排列成多行的方式排布，适用于阻挡显示装置上下侧 的光线射出，从而使从显示装置的上侧或下侧不能看见显示装置显示的图像。
如图 5所示， 为图 1中多个电极块在第一基板上的第四种排布图。 在图 5中， 每个电极块 11为长条形电极块， 且多个长条形电极块等间距排列成多 歹l。如此设置， 可以根据需要对其中一个或几个电极块 11施加电压， 这些施 加有电压的电极块 11与第二透明电极层形成电场， 可以使电致变色层 30与 这些施加有电压的电极块 11 对应的区域变色， 阻挡光线透过； 电致变色层 30与余下没有施加电压的电极块 11对应的区域不变色， 即不影响光的透过。 多个电极块 11以等间距排列成多列的方式排布，适用于阻挡显示装置左右侧 的光线射出，从而使从显示装置的左侧或右侧不能看见显示装置显示的图像。
在上述实施例中， 第二透明电极层可以为平面电极， 即第二透明电极层 是一个整块电极， 其上没有电极图案， 但不限于此。 第二透明电极层也可以 与第一透明电极层结构相同， 即第二透明电极层的电极图案与第一透明电极 层的电极图案相同， 也就是说， 第二透明电极层的电极图案与第一透明电极 层的电极图案是上下镜像对称设置的。 如此设置， 可以使第一透明电极层中 的各个电极块分别与第二透明电极层之间形成电场。
在上述实施例中， 电致变色层 30的材料可以选择有机电致变色材料、无 机电致变色材料或复合电致变色材料，例如， 电致变色层 30的材料可以为三 氧化钨、 三氧化钼、 五氧化二钒、 四硫富瓦烯、 聚噻吩、 紫罗精、 金属酞菁 和聚苯胺中的一种或几种。
如图 6所示， 为本发明实施例提供的电致变色面板的制作流程图。 因电 致变色面板的制作流程与液晶面板的制作流程基本相同， 只是在滴注液晶工 序改为滴注电致变色材料， 这里就不再赘述了。 因此， 电致变色面板可以在 液晶面板生产线上生产， 从而节省生产成本。
本发明实施例同时提供了一种显示装置， 该显示装置包括显示面板以及 具有上述技术特征的电致变色面板， 且电致变色面板位于所述显示面板的显 示区域前方， 用以改变显示面板的视角。 如图 7和图 8所示， 分别为本发明 实施例提供的未对电致变色面板通电时显示装置的光路图和本发明实施例提 供的对电致变色面板通电时显示装置的光路图。 在本实施例中， 显示装置包 括： 背光源 1 ,位于背光源 1前方的液晶面板 2, 以及具有上述技术特征的电 致变色面板 3 , 且电致变色面板 3位于液晶面板 2的显示区域前方， 用以改 变显示面板的视角。
具体实施时， 液晶面板 2和电致变色面板 3可以采用一体式结构， 也可 以采用分体式结构。 在采用一体式结构时， 电致变色面板 3和液晶面板 2共 用一个基板， 其为本领域技术人员所熟知， 这里不再赘述。 当未对电致变色 面板施加电压时， 电致变色面板 3为透明态， 背光源 1发射的光不受影响， 可以从显示装置四周透过， 此时显示装置的视角范围最大； 当对电致变色面 板中的部分电极块施加电压时， 电致变色面板 3变为部分非透明， 背光源 1 发射的光不能从显示装置四周透过， 即背光源 1发射的一部分光被阻挡， 此 时显示装置的视角相较未对电致变色面板 3时变窄。 可见， 采用本发明实施 例提供的电致变色面板可以改变显示装置的视角， 使显示装置具有可调视角 的功能。 需要说明的是， 在上述实施例中是以液晶面板作为显示面板为例进 行说明的， 显示面板还可以是等离子面板、 阴极射线显示器或有机发光二极 管显示面板。
值得一提的是， 上述实施例所描述的电致变色面板， 不仅可以作为改变 显示装置视角的关键器件， 还可以作为显示面板应用在生产和生活中。
综上所述， 在本发明的实施例中， 利用电致变色材料在外加电场的作用 下产生稳定、 可逆的颜色变化的现象， 即表现为透光和不透光的特性， 将电 致变色面板设置在显示面板的前方， 通过控制电致变色面板中电极块的通电 状态， 使得显示装置具有可调视角的功能。 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。
