Description

一种 LED 3D显示装置 技术领域
本发明涉及一种显示装置， 尤其是指一种 LED 3D显示装置。
背景技术
近年来， 显示技术得到快速的发展， 与普通 2D画面显示相比， 3D技术可以使画面变得 立体逼真， 图像不再局限于屏幕平面， 仿佛能够走出屏幕外面， 让观众有身临其境的感觉。 尽管 3D显示技术分类繁多， 不过最基本的原理是相似的， 就是利用人眼左右分别接收不同 画面， 然后大脑经过对图像信息进行叠加产生， 构成一个具有前一后、 上一下、 左一右、 远 一近等立体方向效果的影像。
一般而言， 3D立体显示器一般分为裸眼式、 透镜式、 光栅式等类型。 其中， 裸眼式 3D 显示器需要在特定的观看范围以内才会有较佳的效果， 也就是说， 当使用者在观看范围以外 的位置观看裸眼 3D立体显示器时， 除了可能看到错误的立体影像或完全感觉不到影像的立 体感， 因此， 目前 3D显示器仍以透镜式或光栅式立体显示器为主流。 透镜式 3D显示器包含 透镜面板与液晶面板， 其中透镜面板设置于液晶面板上。 当透镜式 3D显示器显示影像时， 透镜面板会接收液晶面板的影像并产生左、 右眼的分光效果， 让使用者产生立体的感觉。
已知用于户外的大型 LED电视墙仅能呈现 2D显示效果， 无法显示 3D立体画面， 另一 方面， 液晶电视虽然已经发展到具备显示立体画面的能力， 但是， 以目前 LCD面板的制造技 术而言， 仍然难以制造出符合户外大型电视墙的超大面积的 LCD面板， 并且以目前能力能够 制造出来的 LCD面板而言，若拿来使用到大型电视墙上，则电视墙制造成本往往会过于高昂， 令人无法接受。
因此， 为了解决大型 LED电视墙以及 LCD电视墙的缺陷， 提高了一种利用单颗四元色 发光二极体为像素显示元件的 3D立体显示装置。
发明内容
为了解决上述技术问题， 本发明的目的在于提供了一种由四原色发光体作为像素显示元 件， 采用不同排列组合方式构成的大型 LED 3D显示装置。
本发明提供了一种 LED 3D显示装置， 其包括：
多颗发光二极管， 各组发光二极管中设有由四颗单原色的发光体构成的子像素； 多组棱镜， 其分别对称排列于任意两子像素的两侧；
通过每个子像素分别透过其相邻的棱镜形成两组图像， 分别投射入观看者的左右眼。 优选地， 所述多组棱镜分别对称地排列于任意两子像素的左右两侧或上下两侧。 其中， 所述子像素呈条形排布形成一组像素， 或呈田字形组合排布形成一组像素。 所述棱镜分别水 平地设于两侧子像素的左侧和右侧， 或是分别对称竖立地设于像素区的上侧和下侧。 所述四 块像素相互并排组成方形结构像素区， 所述棱镜分别对称竖立于像素区的上侧和下侧。 通过 设置子像素不同的排列方式， 结合棱镜的不同排列方式， 提高像素清晰度， 使得图像的穿透 效果更好。
优选地， 所述四排像素平行排列形成一像素区， 在不同排的像素中， 子像素相错排布， 以使得成像的图像中， 色彩更为柔和， 避免局部色彩对比对过大的现象。
优选地， 所述棱镜的宽度小于或等于两个子像素的宽度， 或小于或等于一个子像素的宽 度。
优选地， 所述子像素分别为白色、 红色、 绿色和蓝色的发光体。 通过单色的发光体分别 构成子像素， 组成 WRGB像素。
与现有技术相比， 本发明 LED 3D显示装置中， 采用了四颗单原色的发光体作为子像素， 经过不同方式的排列组合构成像素， 像素的结构可为条形或方形， 结合棱镜不同排列方式， 棱镜与像素之间可相互平行或垂直， 获得不同的成像效果。 相对于原有子像素相同化的排列 方式， 本发明采用不同列的子像素采用交错的方式排列， 使得不同像素透过棱镜后， 颜色更 为均匀柔和， 光线穿透效果良好， 解决了各颜色对比度较大， 局部颜色过深等现象。 另外， 像素采用田字形排列成方形时， 棱镜的宽度加大， 这种排列方式显示分辨率降低， 但色彩均 匀， 更适用于大型 3D 显示装置的应用， 且制造要求精度低， 提高量产的成品合格率， 适用 于大型 LED电视墙。

具体实施方式
为了解决大型 LED 3D显示的问题， 参照图 1所示， 本发明提供了一种 LED 3D显示装 置， 其包括： 多颗发光二极管， 各组发光二极管中设有由四颗单原色的发光体构成的子像素 1 ; 多组棱镜 2， 其分别对称排列于任意两子像素 1的两侧； 通过每个发光二极管分别透过棱 镜 2形成两组图像， 分别投射入观看者的左右眼。
发光二极管呈现四种不同颜色， 分别为白色 （W)、 红色 （R)、 绿色 （G) 和蓝色 （B )， 不同颜色的发光体分别为子像素， 四个子像素 1组成一个 WRGB像素 10。 棱镜 2分别对称 地排列于子像素 1的两侧， 棱镜 2与子像素 1相互对齐， 其可水平地排列于子像素 1的左侧 和右侧， 也可以垂直地排列于子像素 1的上侧或下侧， WRGB像素 10通过相邻的棱镜 2形 成两组图像， 分别投射入观看者的左右眼， 以在人的大脑中形成 3D影像。
参照图 1所示， 所述子像素 1呈条形排布形成一组 WRGB像素 10， 所述棱镜 2分别水 平地设于两侧子像素 1的左侧和右侧。每列 WRGB像素 10相互平行， 所述四排 WRGB像素 10平行排列形成一像素区 X， 在不同排的 WRGB像素 10中， 子像素 1相错排布， 如第一排 WRGB像素 10中， 由左至右， 子像素 1依次为红色（R)、绿色（G)、蓝色（B )和白色（W); 第二排 WRGB像素 10中， 由左至右， 子像素 1依次为绿色 （G)、 蓝色 （B )、 白色 （W) 和 红色 （R); 第三排 WRGB像素 10中， 由左至右， 子像素 1依次为蓝色 （B )、 白色 （W)、 红色 （R) 和绿色 （G); 第四排 WRGB像素 10中， 由左至右， 子像素 1依次为白色 （W)、 红色 （R)、 绿色 （G) 和蓝色 （B )， 排列顺序不以此为限。 不同列的子像素 1交错排列， 以 提高像素的分辨率， 成像效果更佳， 穿透效果好， 避免在整体或局部图像中， 个别颜色过深， 对比度过大， 色彩平衡度不协调等现象。 LED发光成像时， 每一排的 WRGB像素 10都会透 过相邻的透镜形成两个图像， 如第一排的 WRGB像素 10会透过与其相对齐的棱镜 2向上形 成一组图像， 设为第一上图像， 同时， 也透过第二排的棱镜 2向下形成一组图像， 设为第一 下图像； 同样地， 如第二排的 WRGB像素 10会透过与其相对齐的棱镜 2向上形成一组图像， 设为第二上图像， 同时， 也透过第三排的棱镜 2向下形成一组图像， 设为第二下图像。 这时， 由第一排的 WRGB像素 10形成的第一下图像和第二排的 WRGB像素 10形成的第二上图像 重叠， 产生的图像投射入观看者的右眼 （或左眼） 中， 同样地， 由第二排的 WRGB像素 10 形成的第二下图像和第三排的 WRGB像素 10形成的第三上图像重叠， 产生的图像投射入观 看者的左眼（或右眼）中，使得人的大脑形成 3D视觉影像效果。在本实施例中，通过将 WRGB 四单色像素呈条形排列， 结合棱镜 2呈水平排列， 形成 3D视觉成像效果。
参照图 2所示， 在实施例二中， 子像素 1的排列方式与实施例一相同。 所不同的是， 棱 镜分别对称竖立于像素区 X的上侧和下侧，即各列棱镜 2分别竖立于像素区 X中的第一列子 像素 1的上侧以及第四列子像素 1的下侧， 各列棱镜 2的宽度小于或等于子像素 1的宽度， 优选地， 棱镜 2的宽度与子像素 1的宽度相同。 LED发光成像时， 各列的子像素 1分别透过 相对应的棱镜 2， 直接通过上棱镜形成一组图像， 投射入观察者的右眼中， 通过下棱镜形成 另一组图像， 投射入左眼中， 通过射入图像的错位， 形成 3D视觉成效效果。 在本实施例中， 通过将 WRGB四单色像素呈条形排列， 结合棱镜 2呈垂直排列， 形成 3D视觉成像效果。
参照图 3所示， 在实施例三中， 所述子像素 1呈田字形组合排布形成一组 WRGB像素 10。 在本实施例中， 一组方形的 WRGB像素 10中， 上列子像素为红色 （R) 和绿色 （G)， 下列子像素为蓝色 （B )和白色 （W)， 四个单色子像素组成呈方形。 在一个像素区 Y中， 包 括四个 WRGB像素 10，其组成成方形结构，在像素区 Y的上列和下列，分别设置两个 WRGB 像素 10， 其中， 在每个 WRGB像素中， 子像素 1的排列顺序可以相同或不同。 棱镜 2分别 对称地竖立于像素区 Y的上侧和下侧， 一个棱镜 2与两个子像素 1相对， 即使得两个子像素 可透过一个棱镜成像， 所述棱镜的宽度小于或等于两个子像素的宽度， 优选地， 棱镜的宽度 等于两个子像素的宽度。 LED发光成像时， 各个 WRGB像素 10可分别透过相邻的棱镜 2成 像， 通过上棱镜形成一组图像， 投射入观察者的右眼中， 通过下棱镜形成另一组图像， 投射 入左眼中， 通过射入图像的错位， 形成 3D视觉成效效果。 在本实施例中， 通过将子像素排 列呈田字形， 棱镜垂直竖立， 使得棱镜加宽， 虽降低了图像的分辨率， 但色彩更为柔和， 可 广泛适用于大型的 LED 3D显示装置中， 降低了显示装置的制备精度和难度。
参照图 4所示， 在实施例四中， 子像素 1的排列方式与实施例一相同。 所不同的是， 棱 镜分别对称水平放置于像素区 Y的左侧和右侧。 一个棱镜 2与两个子像素 1相对， 即使得两 个子像素可透过一个棱镜成像。 成像原理与实施例一相同， 故不再赘述。
棱镜与像素之间可采用棱镜水平排列或垂直排列两种，棱镜垂直排列即我们通常裸眼 3D 液晶显示器中棱镜的排列， 该排列通过垂直的棱镜把像素图像分为左右两幅， 即对应人眼的 左右眼， 每一个垂直排列的棱镜都分为左右眼图像， 所以人的左右眼分别接收到不同的图像， 从而在大脑中形成 3D立体效果图像。 而棱镜水平排列则不同， 水平排列的棱镜会通过棱镜 产生上下两幅图像， 我们可以把棱镜 1产生的上下图像叫做第一上图像、 第一下图像， 这样 水平排列的棱镜 2同样在竖直方向紧相连的像素通过水平棱镜 2产生第二上图像、 第二下图 像， 同理水平棱镜 3产生第三上图像、 第三下图像， 这样可以通过控制棱镜与显示屏的距离 使得第一下图像与第二上图像、 第二下图像与第三上图像等等在同一水平线上， 这样人眼在 同一水平线可以同时接收到第一下图像与第二上图像、 第二下图像与第三上图像等等， 这样 人的左右眼就可以分别获得不同图像， 从而形成 3D效果。
这两种排列方式中， 棱镜垂直排列为常见方式， 量产经验丰富， 易于控制。 棱镜水平排 列时， 通过相邻棱镜产生上下图像而分别给人眼左右眼进行区分产生 3D效果， 属于新式方 式， 3D 效果需要精确控制棱镜与显示屏的距离来达到相邻棱镜产生的上下画面在同一水平 线， 可以达到真实性更佳的 3D效果图像。
本发明 LED 3D显示装置中， 采用了四颗单原色的发光体作为子像素， 经过不同方式的 排列组合构成像素， 像素的结构可为条形或方形， 结合棱镜不同排列方式， 棱镜与像素之间 可相互平行或垂直， 获得不同的成像效果。 相对于原有子像素相同化的排列方式， 本发明采 用不同列的子像素采用交错的方式排列， 使得不同像素透过棱镜后， 颜色更为均匀柔和， 光 线穿透效果良好， 解决了各颜色对比度较大， 局部颜色过深等现象。 另外， 像素采用田字形 排列成方形时， 棱镜的宽度加大， 这种排列方式显示分辨率降低， 但色彩均匀， 更适用于大 型 3D显示装置的应用， 且制造要求精度低， 提高量产的成品合格率。
