Description

2D/3D可切换显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种2D/3D可切换显示装置。
背景技术
集成成像技术(Integral Imaging)是由法国科学家M.G.Lippmann在1908年提出的集成摄像技术(Integral Photography)发展而来，其基本原理分为采集阶段与影像重构阶段。采集阶段是利用二维狭缝光栅或二维透镜阵列将空间场景记录到二维狭缝光栅或二维透镜阵列后面的介质上，每个二维狭缝或二维透镜对应其背后介质上的一个元素图像(Elemental Image,EI)，每个元素图像记录了空间场景中的一部分信息，所有元素图像集成起来组成的元素图像阵列就记录了整个空间场景的三维信息。而影像重构阶段是根据光路可逆原理，在元素图像阵列前面放置与记录时同样的二维狭缝光栅或二维透镜阵列，从而在二维狭缝光栅或二维透镜阵列前重构起原始的三维空间场景。
请参阅图1，图1为集成成像3D显示***的成像原理示意图，该集成成像3D显示***包括采集***110、及显示***120，该采集***110包 括图像采集传感器400、及第一二维狭缝光栅300，该显示***120包括液晶面板401、及第二二维狭缝光栅301。
在采集阶段，将物体500放置在第一二维狭缝光栅300前，所述物体500发出的光线经过所述第一二维狭缝光栅300的数个狭缝，传递至所述图像采集传感器400，所述图像采集传感器400记录经过第一二维狭缝光栅300上每一狭缝的光线所对应形成的物体500的一个元素图像，最终在所述图像采集传感器400上得到经过第一二维狭缝光栅300中所有狭缝的光线所对应形成的数个视差不同的物体500的元素图像，构成元素图像阵列，从而完成对物体500的信息采集。
在影像重构阶段，在液晶面板401上显示拍摄到的元素图像阵列，并在液晶面板401前面或后面叠加与所述第一二维狭缝光栅300相同的第二二维狭缝光栅301，从而根据光线可逆原理，通过所述第二二维狭缝光栅301重构出被采集的物体500的图像501，重构图像501能够提供不同方位的视差图像，并结合人眼的视差融合特性，使人们不用通过眼镜就能观看到物体500的3D效果，即人们常说的裸眼3D。
请参阅图2，图2为一种现有的集成成像3D显示装置的结构示意图，该集成成像3D显示装置包括液晶面板100、设于所述液晶面板100下方的 背光模组200、及设于所述液晶面板100与背光模组200之间的二维狭缝光栅600，其中，二维狭缝光栅600也可以设于所述液晶面板100的上方。
所述背光模组200提供的均匀面光源经过所述二维狭缝光栅600后，光线具有方向性，这些光线照射到液晶面板100后，液晶面板100上的不同像素将朝不同的方向发射光线。通过对二维狭缝光栅600的狭缝开口部分与液晶面板100所显示的图像的合理设计，可使得观察者在图2所示的x方向和y方向上看到不同角度的视差图像，从而实现集成成像显示。
然而，现有的集成成像3D显示装置只能用于实现3D效果显示，无法实现2D/3D显示模式的切换，因此有必要研制出一种2D/3D可切换显示装置，以解决上述问题。

请同时参阅图3至图5，本发明提供一种2D/3D可切换显示装置，包括背光模组2、及设于所述背光模组2上的液晶面板1。
所述液晶面板1作为光调制层，优选的，所述背光模组2采用白光OLED。
请同时参阅图4与图5，所述液晶面板1上设有数个依次排列的呈方形的元素图像11，每个元素图像11包括9个像素，呈3像素×3像素排列，其中每个像素分别包括红、绿、蓝子像素。所述背光模组2上对应所述数个元素图像11分别设有数个呈方形的发光单元21。
具体地，每一发光单元21分别包括一位于中间位置的呈方形的中间区域211、及位于所述中间区域211***的周边区域212，所述数个发光单元21的中间区域211分别与所述数个元素图像11相对应。
