为了实现上述目的，本发明采用以下技术方案：
一种基于 柱面透镜发光管的立体大屏幕 ，包括控制器和显示屏，其中，在显示屏上设置多个发光像素，由控制器控制发光像素发光；在所述发光像素上分别设置柱面透镜，根据柱面发光原理， 形成左右眼图像视觉差 。
进一步，所述发光像素为发光管，包括柱面透镜、封装体、引脚和发光芯片，所述发光芯片设置在封装体内，柱面透镜设置在封装体上，引脚与发光芯片连接。所述发光像素的纵切面透镜侧为直线、 外凸或内凹。 所述发光像素 包括两个发光芯片，一个用于显示左眼图像信息，一个用于显示右眼图像信息 。 所述发光像素拆分为左右对称的两部分， 分别显示左眼图像和右眼图像 。所述发光像素为SMD贴片型，其透镜为柱面透镜，或在SMD贴片型发光像素封装体发光面上设置一个柱面透镜罩。所述发光像素 包括显示左眼图像的发光像素和显示右眼图像的发光像素，所述显示左眼图像的发光像素和显示右眼图像的发光像素均包含三基色 RGB 。所述发光像素拆分为左右对称的两个，分别显示左眼图像和右眼图像。
本发明的发光像素使用透镜为柱面的发光管或SMD贴片型发光管，或在SMD贴片的封装体发光面设置一个柱面透镜罩，发光管为单色发光（RGB中的一种），SMD贴片型可为单色发光，也可为三基色发光（包含RGB三种），发光管或SMD贴片型内的发光芯片均可同时显示左眼图像信息和右眼图像信息，柱面透镜或柱面透镜罩的设置， 根据柱面透镜发光原理，形成左右眼图像视觉差，最终在人脑中形成最终立体图像，在观看时人们无需戴任何立体眼镜，实现了裸眼立体大屏幕显示。
而且本发明在发光像素上设置柱面透镜或柱面透镜罩，解决了现有技术中在 LED 立体 大屏幕前面加装类似柱面透镜板，这样的透镜板由于产生严重反射，将会造成显示屏的对比度和色饱和度的大幅度降低的问题；本发明的大屏幕的发光像素或发光点可以 形成一个高清晰度显示的完整像素， 这样使得系统分辨率、对比度、色饱和度没有任何降低，立体显示与平面显示兼容，操作简单，清晰度高。
 有益效果
本发明 在 发光点或者发光像素 上设置柱面透镜， 使用该发光点或者发光像素 制成的大屏幕 分别发出左、右图像的光，左、右眼图像分别进入相对应的左、右眼中，根据柱面透镜发光原理，形成左右眼图像视觉差，最终在人脑中形成最终立体图像，在观看时人们无需戴任何立体眼镜，实现了裸眼立体大屏幕显示。本发明在各发光点或者发光像素 周边仍然采用各种形式的黑底处理，比如但不限于使用黑色塑框等，以增大对比度和色饱和度。
本发明的发光像素 可以同时显示左右眼图像，形成一个高清晰度显示的完整像素， 这样使得系统分辨率、对比度、色饱和度没有任何降低，立体显示与平面显示兼容，操作简单，清晰度高。
本发明的其他优点、目标和特征在某种程度上将在随后的说明书中进行阐述，并且在某种程度上，基于对下文的考察研究对本领域技术人员而言将是显而易见的，或者可以从本发明的实践中得到教导。本发明的目标和其他优点可以通过下面的说明书或者附图中所特别指出的结构来实现和获得。
