Description

一种裸眼3D背光模组、显示装置和显示方法
技术领域
本发明涉及3D显示技术领域，尤其涉及一种裸眼3D背光模组、显示装置和显示方法。
背景技术
裸眼3D能够实现在不使用专用眼镜的情况下，观看文字及图画时呈现出3D影像的效果，采用了视差障壁技术、柱状透镜技术等。
目前，对于裸眼3D显示装置来说，一般都是两视点区域显示，视角范围较窄，观察者只能在这两个区域内看到3D显示影像，当人眼不在这两个区域后，只能看到2D影像或重影，甚至于看不到影像。现有技术中裸眼3D显示装置的具体结构如图1所示：由具有左右两个单元的多组LED组成的薄膜晶体管液晶显示器(Thin FilmTransistor-Liquid Crystal Display，TFT-LCD)发出的背光，在通过视差屏障(parallax barrier)后，仅在中间的一小部分区域可以通过裸眼看到3D图像，而其他区域的3D影像均无法被观察到。
发明内容
(一)要解决的技术问题

至少一个多边棱镜，每个多边棱镜对应一组LED背光源，折射边数为n，用于将经过所述凸透镜后方向一致的平行光折射为n个方向的平行光；
TFT-LCD，刷新频率与所述LED背光源的时序频率一致，用于控制经多边棱镜后的n个方向的平行光的透过率；
多视角视差屏障，用于将经过TFT-LCD的n个方向的平行光在空间中形成n视点区域显示。
进一步地，在所述多边棱镜和所述TFT-LCD之间还包括：

另一方面，本发明还提供一种裸眼3D显示装置，包括如上任一项所述的裸眼3D背光模组。
再一方面，本发明还提供一种裸眼3D显示方法，包括：
通过一组或多组LED背光源发光，每组LED背光源包括n个LED单元，所述n个LED单元以至少240Hz时序发光，n≥4且n为偶数；
将所述LED单元发出的光会聚为方向一致的平行光；
将所述方向一致的平行光折射为n个方向的平行光；
利用刷新频率与所述LED背光源的时序频率一致的TFT-LCD控制所述n个方向的平行光的透过率；
将经过TFT-LCD的n个方向的平行光在空间中形成n视点区域显示。
进一步地，在所述将所述方向一致的平行光折射为n个方向的平行光之后，且在所述利用刷新频率与所述n视点的三维背光的刷新频率一致的TFT-LCD控制所述n个方向的平行光的透过率之前，还包括：
利用扩散片使得n个方向的平行光均匀扩散。
进一步地，
当n＝4时，所述三维背光和所述TFT-LCD的刷新频率为240Hz。
进一步地，
当n＝8时，所述三维背光和所述TFT-LCD的刷新频率为480Hz。
(三)有益效果
可见，在本发明提供的裸眼3D背光模组、显示装置和显示方法中，能够利用多边棱镜和多视角视差屏障的作用，使得人眼在多个区域均能观察到三维图像，大大提高了人眼的三维视角，具有较高的实用价值。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是现有技术中两视点区域显示结构示意图；
图2是本发明实施例裸眼3D背光模组的基本结构示意图；
图3是本发明实施例裸眼3D背光模组的一种优选结构示意图；
图4是本发明实施例4视点区域裸眼3D显示的双向棱镜折射光路图；
图5是本发明实施例4视点区域裸眼3D显示的显示区域示意图；
图6是本发明实施例裸眼3D显示方法的基本流程示意图。
具体实施方式
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中的附图，对本发明实施例中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一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动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。
本发明实施例首先提供一种裸眼3D背光模组，包括：
LED时序板1，其包括一组或多组LED背光源2，每组LED背光源2用包括n个LED单元3，所述n个LED单元3以至少240Hz时序发光，n≥4且n为偶数，参见图2，此时n＝4；
多个凸透镜4，每个凸透镜4对应一个LED单元3，用于将LED单元3发出的光会聚为平行光，所有凸透镜4会聚的平行光方向一致；
至少一个多边棱镜5，每个多边棱镜5对应一组LED背光源2，折射边数为n，用于将经过凸透镜4后方向一致的平行光折射为n个方向的平行光；
TFT-LCD6，刷新频率与LED背光源2的时序频率一致，用于控制经多边棱镜5后的n个方向的平行光的透过率；
多视角视差屏障7，用于将经过TFT-LCD6的n个方向的平行光在空间中形成n视点区域显示。
优选地，为了使得n个方向的平行光均匀扩散，形成n个视域，在多边棱镜5和TFT-LCD6之间还可以包括：扩散片8，见图3。
优选地，当本发明实施例裸眼3D背光模组为4视点区域裸眼3D显示时，n＝4，则LED背光源2和TFT-LCD6的刷新频率需要为240Hz。并且，当n＝4时，多边棱镜为折射边数为4的棱镜，也即双向棱镜，每组LED背光源2发出的4视点的三维背光经凸透镜会聚后，可以被双向棱镜折射为4个方向的平行光，参见图4，以形成4个视域。在最终形成的4视点区域显示中，如图5所示，不论人眼落在4’与3’、3’与2’、2’与1’中的哪个区域之间，均可以观察到3D效果，因而与图1现有技术中的两视点区域显示相比，大大提高了裸眼的三维视角。
优选地，当本发明实施例裸眼3D背光模组为8视点区域裸眼3D显示时，n＝8，则LED背光源2和TFT-LCD6的刷新频率需要为480Hz。
本发明实施例还提供一种裸眼3D显示装置，，包括如上任一项所述的裸眼3D背光模组。
本发明实施例还提供一种裸眼3D显示方法，参见图6，包括：
步骤601：通过一组或多组LED背光源发光，每组LED背光源包括n个LED单元，所述n个LED单元以至少240Hz时序发光，n≥4且n为偶数。
步骤602：将所述LED单元发出的光会聚为方向一致的平行光。
步骤603：将所述方向一致的平行光折射为n个方向的平行光。
步骤604：利用刷新频率与所述LED背光源的时序频率一致的TFT-LCD控制所述n个方向的平行光的透过率。
步骤605：将经过TFT-LCD的n个方向的平行光在空间中形成n视点区域显示。
为了使得n个方向的平行光均匀扩散，形成n个视域，优选地，在将所述方向一致的平行光折射为n个方向的平行光之后，且在利用刷新频率与所述n视点的三维背光的刷新频率一致的TFT-LCD控制所述n个方向的平行光的透过率之前，还可以包括：利用扩散片使得n个方向的平行光均匀扩散。
优选地，当本发明实施例方法为4视点区域裸眼3D显示时，n＝4，则三维背光和TFT-LCD的刷新频率需要为240Hz。
优选地，当本发明实施例方法为8视点区域裸眼3D显示时，n＝8，则三维背光和TFT-LCD的刷新频率需要为480Hz。
可见，本发明实施例至少具有如下有益效果：
在本发明实施例提供的裸眼3D背光模组、显示装置和显示方法中，能够利用多边棱镜和多视角视差屏障的作用，使得人眼在多个区域均能观察到三维图像，大大提高了人眼的三维视角，具有较高的实用价值。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
