Description

3D显示装置 技术领域
本发明的实施例涉及一种 3D显示装置。 背景技术
三维（3D )显示技术是利用双眼立体视觉原理使人获得三维空间感， 其 主要原理是使观看者的左眼与右眼分别接收到不同的影像， 由观看者两眼之 间的瞳距产生的位置差异， 使存在 "双眼视差" 的两副图像构成一对 "立体 图像对" ， 而 "立体图像对" 在经由大脑分析融合后使观看者产生立体感。
目前， 3D显示技术主要有棵眼式和眼镜式两大类。所谓棵眼式就是通过 在显示面板上进行特殊的处理， 把具有双眼视差的左右眼图像分别独立送入 人的左右眼， 从而令用户无需借助眼镜即可棵眼体验立体感觉。
目前， 棵眼 3D显示装置通过在诸如液晶显示器（LCD ) 的显示屏出光 侧设置视差屏障 （Barrier )或柱状透镜等实现 3D显示。 其中， 光栅式视差 屏障 3D显示装置是在显示屏前安装栅状光学屏障来控制或者遮挡光线的行 进方向， 让左右两眼能同时接受到具有视差的左右眼图像， 从而能在大脑中 融合成立体影像。
目前， 可以通过多种方式形成光栅式屏障， 例如可以使用比较廉价的打 印式菲林片来实现光栅式屏障， 多数打印式菲林片的图形是与像素结构相似 的长条状或者长方形状的条纹； 也可以采用可开关的液晶薄膜作为光栅式屏 障形成立体显示， 其原理与打印式菲林光栅一样， 不同之处在于液晶薄膜可 以实现 2D显示状态和 3D显示状态的切换， 即在需要进行 3D显示状态时可 以打开液晶薄膜来实现 3D显示， 在不需要进行 3D显示， 即 2D显示状态时 可以关闭液晶薄膜。
目前的光栅式屏障在 3D显示状态下， 形成的遮挡条纹一般都是长条状 或者长方形状， 这种遮挡条纹在实现 3D显示效果的同时， 会因对光线的遮 挡而降低显示的亮度， 影响观看者的视觉体验。 发明内容

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 筒单地介绍，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。

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。
本发明的实施例提供的 3D显示装置是利用小孔成像的原理实现 3D显示 的， 下面对小孔成像的条件进行筒要说明。 如图 1所示， 设发光物体的高度 为 h, 光栅的孔径为 d, 发光物体到光栅的距离即物距为 u , 小孔成像的临界 距离为 V , 由三角形相似原理可得： v/d= ( v+u ) /h , 因此， 临界距离 v=ud/ ( h-d )。 从公式中可以看出， 当发光物体的高度 h大于光栅的孔径 d时， 临 界距离 V是正值， 当发光物体的高度 h小于光栅的孔径 d时， 临界距离 V是 负值， 无意义， 当发光物体的高度 h等于光栅的孔径 d时， 临界距离 V为无 穷大， 也无意义。 因此， 小孔成像的一个重要条件是发光物体的高度 h必须 大于光栅的孔径 d, 即像素单元的大小必须大于光栅的孔径。 当发光物体的 高度 h小于或等于 d时， 像屏无论放在何处， 像屏上都看不到倒立的像， 即 发光物体的光线传播方向不改变。
本发明实施例提供的一种 3D显示装置， 如图 2所示， 包括： 显示面板 01 , 位于显示面板 01 出光侧且具有阵列排布的孔状透光区域的第一光栅层

03, 以及调节第一光栅层 02和第二光栅层 03的相对移位以实现 2D显示状 态与 3D显示状态切换的调节装置 04。其中，第一光栅层 02具有的孔状透光 区域与第二光栅层 03具有的孔状透光区域——对应； 显示面板 01内具有阵 列排布的像素单元 05。
在 2D显示状态时， 如图 3a所示， 每一对孔状透光区域在显示面板 01 上投影的重叠区域（图中虚线所示）覆盖至少一个像素单元 05的区域；
在 3D显示状态时， 如图 3b所示， 每一对孔状透光区域在显示面板 01 上投影的重叠区域（图中虚线所示） 小于一个像素单元 05的区域。
在具体实施时示例性地， 根据本发明实施例的显示面板 01 可以是液晶
( 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 3D显示装置中，通过调节第一光栅层 02具有的各 孔状透光区域和第二光栅层 03 中对应的各孔状透光区域相互的重叠区域是 否满足小孔成像的条件，来实现 2D显示状态与 3D显示状态的切换，其中像 素单元的大小相当于发光物体的大小， 重叠区域的大小相当于光栅的孔径大 小。
具体地， 为了使第一光栅层 02和第二光栅层 03中的各孔状透光区域的 重叠区域的大小分别能满足 2D显示状态和 3D显示状态的条件。 即在 2D显 示状态下， 根据上述小孔成像的条件可知， 如图 3a所示， 需要使得第一光栅 层 02和第二光栅层 03中对应的各孔状透光区域的重叠区域（即光栅的孔径） 不小于像素单元 05的大小 （即发光物体） ； 在 3D显示状态下， 如图 3b所 示， 根据上述小孔成像的条件可知， 需要使得第一光栅层 02和第二光栅层 03中对应各孔状透光区域的重叠区域（即光栅的孔径） 小于像素单元 05的 大小 （即发光物体） 。 示例性地， 若将第一光栅层 02和第二光栅层 03中的 各孔状透光区域的孔径设置为大于一个像素单元， 例如两个像素单元时， 会 难于从 2D状态切换至 3D状态， 并且， 各孔状透光区域的孔径越大， 为保证 能从 2D状态切换至 3D状态，需要将各孔状透光区域之间的黑色遮挡部分设 置较大， 会大大降低显示亮度和分辨率。 若将第一光栅层 02和第二光栅层 03中的各孔状透光区域的孔径设置成小于一个像素单元时， 仅能满足 3D显 示状态的小孔成像条件， 无法进行 2D显示状态的切换。 因此， 为尽可能实 现在 2D状态下的显示具有较高的分辨率以及较少的亮度损失， 同时又能在 3D状态下能够满足小孔成像的条件， 在具体实施时， 一般如图 3a和图 3b 所示将每一对孔状透光区域与每个像素单元 05的位置——对应，即第一光栅 层 02具有的孔状透光区域和第二光栅层 03具有的孔状透光区域与像素单元 05的位置均——对应。
图 4a和图 4b分别为在 2D显示状态下和 3D显示状态下， 第一光栅层 02和第二光栅层 03中的对应的各孔状透光区域的重叠区域俯视示意图。 图 5a和图 5b分别为在 2D显示状态下和 3D显示状态下， 第一光栅层 02和第 二光栅层 03中的对应的各孔状透光区域截面示意图。
并且， 在具体实施时， 一般将第一光栅层中各孔状透光区域的总面积设 置为占第一光栅层总面积的 60%-90%, 即第一光栅层中黑色遮挡部分的总面 积占第一光栅层总面积的 10%-40%；将第二光栅层中各孔状透光区域的总面 积设置为占第二光栅层面积的 60%-90%, 即第二光栅层中黑色遮挡部分的总 面积占第二光栅层总面积的 10%-40%,以便在第一光栅层和第二光栅层之间 相对移位后， 利用黑色遮挡部分调节两层光栅层中对应各孔状透光区域的重 叠区域的大小。
在具体实施时，第一光栅层和 /或第二光栅层一般可以为由黑矩阵材料制 备而成的光栅层， 在黑矩阵材料中制备各孔状透光区域。
进一步地，为了保证在 2D显示状态时，第一光栅层 02和第二光栅层 03 中的各孔状透光区域较少的遮挡显示面板 01的像素单元的出光区域，可以将 第一光栅层 02具有的各孔状透光区域与第二光栅层 03具有的各孔状透光区 域设置为形状和尺寸均相同， 即第一光栅层 02和第二光栅层 03的内部结构 一致， 两者可上下互换。
进一步地，为了保证 3D显示装置在 2D显示状态下具有较少的亮度损失， 可以将第一光栅层 02具有的各孔状透光区域与第二光栅层 03具有的各孔状 透光区域的形状设置为与各像素单元的形状一致， 例如可以为方形或圓形， 本发明的实施例在此不作限定。
下面以第一光栅层 02具有的各孔状透光区域、 第二光栅层 03具有的各 孔状透光区域以及各像素单元的形状均为长方形为例进行说明， 其中， 如图 6所示，一个像素单元由红绿蓝 RGB三个亚像素单元组成， 一个像素单元的 宽度为 X, 长度为 y。
具体地示例性地， 调节第一光栅层和第二光栅层的相对移位以实现 2D 显示状态与 3D显示状态切换的调节装置 04, 可以包括：
驱动第一光栅层沿像素单元行的延伸方向平移的第一驱动部件； 和 /或， 驱动第二光栅层沿像素单元行的延伸方向平移的第二驱动部件。
在具体实施时，在 2D显示状态和 3D显示状态之间相互切换时，可以仅 驱动第一驱动部件， 如图 2所示， 使第一光栅层 02相对第二光栅层 03沿着 像素单元行的延伸方向 （箭头方向）平移； 也可以仅驱动第二驱动部件， 使 第二光栅层 03相对第一光栅层 02沿着像素单元行的延伸方向 （箭头方向） 平移； 当然， 为了节省机械结构的移动距离， 还可以同时驱动第一驱动部件 和第二驱动部件， 使第一光栅层和第二光栅层同时相对平移， 实现调节两光 栅层中相应各孔状透光区域的重叠区域大小。 在具体实施时， 可以在 3D显 示状态下， 调整第一光栅层和第二光栅层使得二者发生（n+1/4 ) X的相对位 移， 其中 n为整数， X为一个像素单元的宽度。 在具体实施时， 第一驱动部件和第二驱动部件可以通过步进马达， 与步 进马达的输出轴同轴固定的齿轮， 以及设置在第一光栅层和第二光栅层上的 齿条实现对应的第一光栅层或第二光栅层的平移过程， 当然， 也可以通过其 他微型机械装置实现， 在此不作限定。
进一步地， 根据小孔成像原理， 在满足小孔成像条件下， 如图 1所示， 成像距离 v0可以筒化为： v0=Eu/h, 其中 E为人眼两瞳孔的距离， v0为成像 距离。 根据此公式， 在具体实施时， 本发明实施例提供的 3D显示装置， 还 可以包括： 调节显示面板 01与第一光栅层 02之间距离的第三驱动部件； 设 置于显示面板正面的信号采集单元， 该信号采集单元具有用于采集显示面板 前侧观看者面部与显示面板之间距离信息的距离采集模块； 与距离采集模块 和第三驱动部件信号连接的信号处理单元， 当距离采集模块采集的距离信息 变化时生成驱动信号， 第三驱动部件根据驱动信号调节显示面板与第一光栅 层的相对距离， 以达到根据观看者与显示面板的距离调节第一光栅层与显示 面板之间距离， 实现 3D显示状态的最佳观看效果。
例如： 以分辨率为 1280*800的 10英寸的 3D显示装置为例， 其中， 每 个亚像素单元的宽度约为 55 μ ιη, 高度约为 180 μ ιη; 则第一光栅层和第二 光栅层中各孔状透光区域的孔径宽度为 160 μ ιη, 高度为 180 μ ιη, 人眼两瞳 孔的距离一般为 6.5cm。通过检测得到若在观看者在距离显示面板 1.4m处观 看， 通过计算可以得出第一光栅层距离显示面板的放置距离应约为 2mm, 通 过第三驱动部件调节第一光栅层与显示面板之间的距离， 可以实现观看者的 最佳 3D观看效果。
本发明实施例提供的一种 3D显示装置， 在显示面板的出光侧设置具有 阵列排布的孔状透光区域的第一光栅层， 在第一光栅层上设置具有阵列排布 的孔状透光区域的第二光栅层， 其中第一光栅层具有的孔状透光区域与第二 光栅层具有的孔状透光区域——对应， 通过调节第一光栅层与第二光栅层中 各孔状透光区域的重叠区域大小是否满足小孔成像条件， 以实现 2D显示状 态与 3D显示状态的切换。 具体通过调节装置调节第一光栅层和第二光栅层 的相对移位， 在 2D显示状态时， 调节每一对孔状透光区域在显示面板上投 影的重叠区域， 使其覆盖至少一个像素单元的区域， 显示面板显示的图像经 过每对孔状透光区域后实现正常显示； 在 3D显示状态时， 调节每一对孔状 透光区域在显示面板上投影的重叠区域， 使其达到小孔成像条件， 即， 小于 一个像素单元的区域， 实现对显示面板中各亚像素单元出射光角度的调节， 进而实现左眼图像和右眼图像分别汇聚于不同位置， 实现棵眼 3D显示， 相 对于遮挡条纹可以减少对光线的遮挡，避免减低显示亮度， 实现高亮度的 3D 显示。 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。
