图 6为本发明一种具有穿透效果的显示面板实施例六的结构示意图；
具体实施方式
本发明提供了一种具有穿透效果的显示面板， 具有以下工作模式： 透明显示模式、 不透 明显示模式和穿透显示模式， 以下根据不同工作模块分别介绍显示面板的结构。
参照图 1所示， 实施例一， 所述具有穿透效果的显示面板， 包括若干个主像素， 每个主 像素包括若干个子像素， 每个子像素 100包括第一基板 1、 第二基板 2以及在两基板之间的 显示层 3， 显示层中分布有液晶分子 4， 其中， 所述各个子像素中分别设有透明电极 5， 各透 明电极 5之间相互隔离， 通过对任意子像素的透明电极 5施加电压， 调整显示面板的显示状 态。 其中， 透明电极 5设于第一基板 1的下方和第二基板 2的上方， 所述液晶分子为全息高 分子分散型液晶分子 （HPDLC)。 当对透明电极 5施加电压时， 液晶分子 4顺着电场有序地 排列， 每个液晶分子的排列方向均相同， 对正面入射光而言， 这些液晶分子具有相同的折射 系数， 若选用的基板材料的折射系数与液晶相同， 则在显示层 3中， 没有任何折射或反射现 象产生， 入射光线可穿透显示层 3， 使得整个显示面板呈现清澈透明状态。
参照图 2所示， 对显示面板中各个子像素分别进行通电控制， 以呈现穿透显示的效果。 在实施例二中， 最右侧子像素的透明电极不通电， 左侧两个子像素的透明电极通电。 这时， 在左侧两个子像素中， 液晶分子在电场的作用下有序排列， 使入射光线可穿透该两个子像素， 在该区域呈现穿透现象； 而在最右侧子像素的区域， 因液晶分子的折射系数不同， 在各个液 晶分子的表面产生折射和反射现象， 经过多次折射和反射后， 产生了散射， 将入射光线反射 回观测者， 使得观测者可看到显示面板背后的背景画面。 在左侧两个通电子像素区域， 光线 穿透， 呈现穿透状态。 因此， 当部分子像素通电， 部分子像素不通电时， 观测者站在显示面 板的前方， 可看到画面显示的同时， 还可观测到显示面板后方的背景， 产生未来感的画面， 但背景会影响到使用者看画面的清晰度， 同时在操作者的对侧， 也可以看到操作者的画面。
参照图 3所示， 在实施例三中， 所述显示面板进一步增设遮光控制层 6， 所述遮光控制 层 6由电润湿显示面板 （EWD， Electro Wetting Display) 形成。 通过遮光控制层 6对光线的 遮光或透射进行调整。 其中， 所述电润湿显示面板包括正电极 60、 负电极 61、 极性溶液层 62和非极性溶液层 63， 非极性溶液 63层设于电极之上， 所述负电极 61设于正电极 60之上， 非极性溶液层 63设于负电极 61之上。 当电润湿显示面板通电状态时， 所述非极性溶液层 63 可收缩至像素边缘， 使得光线可透过； 当电润湿显示面板在非通电状态时， 非极性溶液层 63 布满整个遮光控制层 6， 将入射光线吸收。 通过控制电润湿显示面板的通电状态， 改变非极 性溶液层 63在遮光控制层 6中的状态， 以控制对入射光线的吸收或穿透。在电润湿显示面板 施加电压前， 在遮光控制层 63中， 非极性溶液层 63平铺布满， 这时， 当光线射入后， 光线 被非极性溶液层 63吸收， 产生遮光效果， 可将背景隔离， 增加清晰度， 同时操作者对侧也看 不到画面， 避免操作者隐私泄露。
参照图 4所示， 当电润湿显示面板不导通， 且至少一组子像素的显示层导通时， 在非通 电子像素区域， 遮光控制层的非极性溶液布满整个遮光控制层， 显示层中液晶分子将光线反 射， 呈现画面； 在通电子像素区域， 光线穿透显示层， 并由遮光控制层的非极性溶液层吸收， 整体呈现不透光显示画面状态。 在实施例四中， 当电润湿显示面板不导通， 左侧两个子像素 的显示层不通电， 右侧子像素的显示层通电， 这时， 左侧两个子像素的显示层中， 液晶分子 将入射光线反射， 呈现画面， 右侧子像素的显示层中， 光线可穿透显示层， 由于电润湿显示 面板不通电， 非极性溶液层将将光线吸收， 呈现黑色状态。
参照图 5所示， 当电润湿显示面板导通， 且全部子像素的显示层导通时， 在各子像素的 遮光控制层中， 非极性溶液层被吸引而收缩至像素边缘， 入射光线穿透显示层和遮光控制层， 整体呈透明状态。 在实施例五中， 当电润湿显示面板导通， 遮光控制层中的非极性溶液层被 吸引而收缩至像素的边缘， 呈现透明显示状态； 若显示层也通电时， 光线穿透显示层和遮光 控制层， 呈现透明状态。
参照图 6所示， 当电润湿显示面板导通， 且部分子像素的显示层不导通时， 在遮光控制 层中， 各子像素的非极性溶液层均被吸引而收缩至像素边缘； 在通电子像素区域， 入射光线 穿透显示层和遮光控制层， 在非通电子像素区域， 入射光线经显示层的液晶分子反射， 呈现 画面， 整体呈现透明显示状态。 在实施例六中， 当电润湿显示面板导通， 而左侧两个子像素 的显示层不通电， 则液晶分子将光线反射， 呈现画面， 右侧子像素的显示层通电， 光线可穿 透显示层和遮光控制层， 维持透明显示状态。
本发明的一种具有穿透效果的显示面板， 包括若干个主像素， 每个主像素包括若干个子 像素， 每个子像素包括第一基板 1、 第二基板 2和第三基板， 在第一基板和第二基板之间为 显示层， 显示层中分布有液晶分子， 在第一基板和第二基板之间设有透明电极， 控制液晶分 子的转向； 在第二基板和第三基板之间为遮光控制层， 遮光控制层由电润湿基板形成， 电润 湿基板中包含有极性溶液层和非极性溶液层， 通过部分或全部子像素施加电压， 控制非极性 溶液层的走向， 调整显示面板的显示状态。
本发明具有穿透效果的显示面板中， 通过分别单独控制各子像素的显示层通断状况， 以 控制液晶分子对入射光线的折射、 反射或透射， 当显示层不通电时， 光线经液晶分子反射或 折射， 当显示层通电时， 光线可透射。 同时， 结合控制遮光控制层的通断状况， 以控制非极 性溶液层对入射光线的吸收或透射， 不通电时， 非极性溶液层平铺于遮光控制层上， 经显示 层入射的光线可被非极性溶液层吸收， 遮光并呈现画面， 通电时， 非极性溶液层被吸引而收 缩至像素边缘， 光线由显示层和遮光控制层， 呈现透明效果。 通过分别改变子像素的显示层 和遮光控制层通断， 获得不同的显示效果， 如透明状态、 穿透显示状态、 不透明显示状态等， 增添了显示面板的艺术效果和成像的多样化， 并且， 提高画面的清晰度， 保护操作者的隐私。
