技术领域
本发明涉及图像显示技术领域，尤其涉及一种实现三维(three dimensional，3D)成像的显示屏。
背景技术
随着科学技术和人类生活水平的不断发展，显示器显示二维(two dimensional，2D)图像已不能满足观察者的需求，显示器显示3D立体图像已成为热门技术之一，3D立体图像液晶显示器能够将场景的三维信息完全的再现出来，显示具有纵深感的图像。目前的3D图像观看一般都需要使用专用的3D眼镜来观看，舒适度不强，不利于3D技术的推广。因此，如何设计一种具有3D显示效果的屏幕，使得观察者无需佩戴专用3D眼镜就能获得3D图像信息是一大技术难点。
发明内容
有鉴于此，有必要提供一种实现3D成像的显示屏，其无需通过专用3D眼镜就能获得3D图像信息。
本发明一实施方式提供一种实现3D成像的显示屏，包括玻璃层、薄膜晶体管(ThinFilm Transistor，TFT)层、背光层、基体层、感应层及驱动模块。所述基体层设置于所述玻璃层及所述TFT层之间，所述基体层上设置有多个三色发光二极管组件。所述玻璃层上设置有多个凸透镜单元，每一凸透镜用于对应至每一三色发光二极管组件。所述驱动模块用于驱动并控制所述多个三色发光二极管组件发射出的光线在不同空间层聚集并形成多个光聚集点。所述感应层设置于所述玻璃层的上方，所述感应层用于侦测每一光聚集点到所述感应层的距离。所述驱动模块还用于根据每一光聚集点到所述感应层的距离来控制每一凸透镜单元对每一光聚集点进行焦距变换。

优选地，所述每一凸透镜单元包括并列设置的第一凸透镜及第二凸透镜，所述驱动模块用于根据每一光聚集点到所述感应层的距离来控制对应凸透镜单元中的第一凸透镜及第二凸透镜的外壁进行伸缩，以实现对每一光聚集点进行焦距变换。
优选地，当所述光聚集点到所述感应层的距离越大，所述第一凸透镜及第二凸透镜的凸起程度越大。
优选地，所述每一凸透镜内部设置有线圈，每一凸透镜外壁的一侧边为磁性S极材料，另一侧边为磁性N极材料。

优选地，所述基体层与所述玻璃层之间还设置有至少两个隔圈。
本发明一实施方式提供还提供一种实现3D成像的显示屏，包括玻璃层、TFT层、背光层、基体层及驱动模块。所述基体层设置于所述玻璃层及所述TFT层之间，所述基体层上设置有多个三色发光二极管组件。所述玻璃层上设置有多个凸透镜单元及多个传感器，每一凸透镜用于对应至每一三色发光二极管组件。所述驱动模块用于驱动并控制所述多个三色发光二极管组件发射出的光线在不同空间层聚集并形成多个光聚集点。所述多个传感器用于分别侦测每一光聚集点到所述玻璃层的距离。所述驱动模块还用于根据每一光聚集点到所述玻璃层的距离来控制每一凸透镜单元对每一光聚集点进行焦距变换。

主要元件符号说明
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参阅图1-4，在一实施方式中，一种实现3D成像的显示屏100包括玻璃层1、TFT层2、背光层3、基体层4、感应层5及驱动模块6。感应层5可以用来接收触摸指令。背光层3用于发射光线，以提供背景光源。TFT层2用于控制背光层3投射出来的光的显示。基体层4设置于玻璃层1及TFT2层之间，基体层4上设置有多个三色发光二极管组件。玻璃层1上设置有多个凸透镜单元，每一凸透镜用于对应至每一三色发光二极管组件。
在一实施方式中，多个三色发光二极管组件以三个三色发光二极管组件7a、7b、7c为例。三色发光二极管组件的数量可以多于三个，在发明的技术方案中，不对三色发光二极管组件的数量进行限制。由于每一凸透镜用于对应至每一三色发光二极管组件，故多个凸透镜单元同样以三个凸透镜单元8a、8b、8c为例，凸透镜单元的数量同样可以多于三个，凸透镜单元的数量优选与三色发光二极管组件的数量相同。
驱动模块6用于驱动并控制多个三色发光二极管组件7a、7b、7c发射出的光线在不同空间层聚集并形成多个光聚集点。感应层5设置于玻璃层1的上方，感应层5用于侦测每一光聚集点到感应层5的距离。驱动模块6还用于根据每一光聚集点到感应层5的距离来控制每一凸透镜单元8a、8b、8c对每一光聚集点进行焦距变换，进而使得显示屏100输出的光产生空间层次感，使得显示的图像有一种突出显示屏外的效果，产生3D成像效果。
在一实施方式中，基体层4优选为柔性的聚酰亚胺层。感应层5包括多个传感器50a、50b、50c(在一实施方式中，传感器数量以3个为例)，传感器50a、50b、50c的数量优选与三色发光二极管组件的数量相同。每一传感器50a、50b、50c用于对应侦测每一光聚集点到感应层5的距离。在本发明的其他实施方式中，感应层5可以省略，多个传感器50a、50b、50c可以整合在玻璃层1上，此时，每一传感器50a、50b、50c用于对应侦测每一光聚集点到玻璃层1的距离，驱动模块6根据每一光聚集点到玻璃层1的距离来控制每一凸透镜单元8a、8b、8c对每一光聚集点进行焦距变换。
在一实施方式中，每一三色发光二极管组件7a、7b、7c包括一红色发光二极管R、一绿色发光二极管G及一蓝色发光二极管B，三色发光二极管R/G/B同样可以由驱动模块6驱动点亮。当在基体层4的下方与三色发光二极管R/G/B的上方加载电压时，三色发光二极管R/G/B将会在柔性基体层4的支撑下发生偏转。具体地，当驱动模块6加载不均匀的电压至三色发光二极管组件7a中的红色发光二极管R、绿色发光二极管G、蓝色发光二极管B上方与基体层4的下方时，红色发光二极管R、绿色发光二极管G、蓝色发光二极管B在基体层4上发生不同角度的偏转，进而发射出的光线形成一光聚集点。当多个三色发光二极管组件7a、7b、7c的光聚集点位于不同平面时，将在不同空间层形成多个光聚集点。
在一实施方式中，基体层4与玻璃层1之间还设置有至少两个隔圈S1、S2，从而可以避免当三色发光二极管R/G/B在柔性基体层4的支撑下发生偏转时由于空间受限而不能偏转成功。
在一实施方式中，每一透镜单元8a、8b、8c优选包括第一凸透镜80及第二凸透镜82。第一凸透镜80及第二凸透镜82并列设置，进而可以实现变焦功能。由于每一光聚集点到感应层5的距离可能存在差异。驱动模块6用于根据每一光聚集点到感应层5的距离来控制对应凸透镜单元中的第一凸透镜及第二凸透镜的外壁进行伸缩，以实现对每一光聚集点进行焦距变换。
请同时参阅图5，每一凸透镜80、82内部设置有线圈CO，每一凸透镜外壁的一侧边为磁性S极材料，另一侧边为磁性N极材料。当线圈CO通电时，线圈CO将会产生磁场，不同的电流大小使得线圈CO产生的磁场强度不同。线圈CO内的N极可以吸引凸透镜外壁为磁性S极材料的侧边，线圈CO内的S极可以吸引凸透镜外壁为磁性N极材料的侧边，进而实现控制凸透镜的外壁进行伸缩，实现调节凸透镜的变焦参数。驱动模块6还用于根据每一光聚集点到感应层5的距离来调整流经每一凸透镜内部的线圈的电流大小，进而可以实现对光聚集点进行不同程度的焦距变换。
请同时参阅图6-7，当光聚集点到感应层5的距离越大，第一凸透镜及第二凸透镜的凸起程度优选越大。图7中的凸透镜凸起层度大于图6中的凸透镜凸起层度。
上述实现3D成像的显示屏通过控制每一像素点中的三色发光二极管发生角度偏转，达到光线在不同空间层聚集的效果并利用透镜变焦使得显示屏输出的光线产生空间层次感，进而来实现3D显示效果，同时使用者无需通过专用3D眼镜就能获得3D图像信息。
对本领域的技术人员来说，可以根据本发明的发明方案和发明构思结合生产的实际需要做出其他相应的改变或调整，而这些改变和调整都应属于本发明所公开的范围。
