反射式3D显示装置及显示方法
本申请要求于2017年4月7日递交的中国专利申请第201710225068.3号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本公开涉及显示装置领域，具体涉及反射式3D显示装置及显示方法。
背景技术
立体显示(即3D显示)技术主要是根据人类的视觉来获得同一物体在不同角度上的两幅图像，并将这两幅图像分别投射至人的左眼和右眼中，从而使人的左眼和右眼中的图像具有一定的视差。大脑对具有视差的左眼图像和右眼图像进行合成，就会产生深度知觉，即感知到立体图像。由此，立体显示技术产生立体图像的显示效果。
目前，3D显示技术主要分为眼镜式和裸眼式两大类。眼镜式3D显示技术需要用户佩戴专用的眼镜，因此不便用于便携式设备。在可移动的电子产品中更注重裸眼式3D显示技术。裸眼3D显示技术主要分为柱状透镜式和光栅式。但是，对于柱状透镜式裸眼3D显示技术，在某些观看角度会出现影像重叠的情况，分辨率损失严重，且不能与2D模式兼容；对于光栅式裸眼3D显示技术，其亮度较低，分辨率损失严重，对视角要求严格。

具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。如图1-3所示，本公开的实施例提供一种反射式3D显示装置，包括：显示面 板1、人眼追踪单元和MEMS(Micro-Electro-Mechanical Systems)反光镜2。显示面板1包括多列像素，其中，所述多列像素包括交替设置的左眼像素L的列和右眼像素R的列，所述左眼像素L用于形成左眼图像，所述右眼像素R用于形成右眼图像。人眼追踪单元用于识别观看所述显示面板的人的人眼的位置信息。多个MEMS反光镜2位于所述显示面板1的与显示面相背对的一侧，用于根据所述人眼的位置信息进行旋转，以调整照射在MEMS反光镜2上的光的出射方向，使得通过所述显示面板1中的左眼像素L出射的光线入射至人的左眼，通过所述显示面板1中的右眼像素R出射的光线入射至人的右眼，以形成3D显示画面。
作为本公开的实施例一种实施方式，如图4所示，显示装置中的多个MEMS反光镜2包括第一MEMS反光镜21和第二MEMS反光镜22，且每个第一MEMS反光镜21与每一个左眼像素L对应设置，每个第二MEMS反光镜22与每一个右眼像素R对应设置。在这种情况下，每个第一MEMS反光镜21用于根据人眼追踪单元所采集的人的左眼位置信息进行旋转，以调整照射在第一MEMS反光镜21上的光的出射方向，使得通过所述左眼像素出射的光线入射至人的左眼，并且每个第二MEMS反光镜22用于根据人眼追踪单元所采集的人的右眼位置信息进行旋转，以调整照射在第二MEMS反光镜22上的光的出射方向，使得通过所述右眼像素出射的光线入射至人的右眼。
具体地，通过图像显示控制单元向显示面板1上的左眼像素L写入与左眼图像对应的数据信号，以及向显示面板1上的右眼像素R写入与右眼图像对应的数据信号，使得左眼图像和右眼图像在行方向上交替显示。在这种情况下，外界光线照射至与左眼像素L位置对应的第一MEMS反光镜21，所述第一MEMS反光镜21根据人的左眼位置信息发生旋转，以使出射光线具有指向性，所述具有指向性的光线通过显示面板1上的左眼像素L出射至人的左眼，以在人的左眼中显示左眼图像。类似地，外界光线照射至与右眼像素R位置对应的第二MEMS反光镜22，所述第二 MEMS反光镜22根据人的右眼位置信息发生旋转，以使出射光线具有指向性，所述具有指向性的光线通过显示面板1的右眼像素R出射至人的右眼，以在人的右眼中显示右眼图像。之后，大脑对左眼图像和右眼图像进行分析处理和合成，从而实现裸眼3D显示。
作为本公开的实施例的另一种实施方式，如图5所示，显示装置中的多个MEMS反光镜2包括第一MEMS反光镜21和第二MEMS反光镜22，且多个第一MEMS反光镜21与每个左眼像素对应设置，多个第二MEMS反光镜22与每个右眼像素对应设置
具体地，通过图像显示控制单元向显示面板1上的左眼像素L写入与左眼图像对应的数据信号，以及向显示面板1上的右眼像素R写入与右眼图像对应的数据信号，使得左眼图像和右眼图像在行方向上交替显示。在这种情况下，外界光线照射至与每个左眼像素L对应设置的多个第一MEMS反光镜21，所述多个第一MEMS反光镜21中的每一个分别根据观看显示面板1的不同的左眼位置信息发生旋转，使得从与同一个左眼像素L对应的位置出射的光线可具有不同的指向性，以进入不同的左眼，从而在每个左眼中显示左眼图像。类似地，所述多个第二MEMS反光镜22中的每一个分别根据观看显示面板1的不同的右眼位置信息发生旋转，使得从与同一个右眼像素R对应的位置出射的光线可具有不同的指向性，以进入不同的右眼，从而在每个右眼中显示右眼图像。由此，实现了在多个视点观看显示面板1时针对所述多个视点中的每一个的3D显示，而不会损失分辨率。
本实施方式中，不同的左眼及不同的右眼可以指同一个人(例如在不同视点处时)的左眼和右眼，也可以指不同人的左眼和右眼。
作为本公开的实施例的再一种实施方式，如图6所示，将多列所述像素划分为多个像素组，每个所述像素组包括相邻设置的一个左眼像素L和一个右眼像素R，且每个MEMS反光镜2与每个所述像素组对应设置。每个MEMS反光镜用于在第一时刻根据 所述人眼追踪单元所采集的人的左眼位置信息进行旋转，以调整照射在每个所述MEMS反光镜上的光的出射方向，使得通过所述左眼像素出射的光线入射至人的左眼，以及在第二时刻根据所述人眼追踪单元所采集的人的右眼位置信息进行旋转，以调整照射在每个所述MEMS反光镜上的光的出射方向，使得通过所述右眼像素出射的光线入射至人的右眼。
具体地，在第一时刻，通过图像显示控制单元向显示面板1上的左眼像素L写入与左眼图像对应的数据信号，在这种情况下，外界光线照射至MEMS反光镜2上，每个MEMS反光镜2根据左眼的位置信息发生旋转，以使MEMS反光镜2反射的光线指向人的左眼，以在人的左眼中显示左眼图像。在第二时刻，通过图像显示控制单元向显示面板1上的右眼像素R写入与右眼图像对应的数据信号，在这种情况下，每个MEMS反光镜2根据右眼的位置信息发生旋转，以使MEMS反光镜2反射的光线指向人的右眼，以在人的右眼中显示右眼图像。之后，大脑对左眼图像和右眼图像进行分析处理和合成，从而实现裸眼3D显示。
需要说明的是，每个第一时刻和每个第二时刻的持续时间很短，而且每个第一时刻和每个第二时刻的时间间隔很小，使得人眼看到的显示画面是连续的。
在本公开的实施例的一些实施方式中，MEMS反光镜2可以为静电驱动的MEMS反光镜2。静电驱动的MEMS反光镜可以采用硅材料制备、其制造工艺与MEMS工艺完全兼容，且其驱动功耗很低、制造工艺较为简便。静电驱动的MEMS反光镜利用电容极板间电荷的静电力驱动MEMS微结构的运动，驱动功耗仅微瓦量级。当然，MEMS反光镜2也可以采用其它驱动方式的MEMS反光镜2。
在本公开的实施例的一些实施方式中，人眼追踪单元可以为摄像头。当然，人眼追踪单元也可以采用红外等其他元件。
在本公开的实施例的一些实施方式中，显示装置中的显示面板1可以为液晶显示面板1。同时，在显示装置中应用MEMS反 光镜2的情况下，可以利用外界光源取代显示面板1中的背光源，从而使得功耗较低、显示装置更加轻薄。当然，本公开的实施例中的显示装置还可以包括设置在显示面板的显示面侧的前置光源。在这种情况下，即使外界环境光不够充足也可以通过前置光源为显示面板提供光源，不会影响显示面板的正常显示。
如上所述，根据本公开的实施例的显示装置中的显示面板1包括多列像素，其中所述多列像素包括交替设置的左眼像素L的列和右眼像素R的列，左眼像素L用于形成左眼图像，右眼像素R用于形成右眼图像。因此可以通过图像显示控制单元，在显示面板1的行方向上交替显示左眼图像和右眼图像。即，通过图像显示控制单元向左眼像素L写入与左眼图像对应的数据信号，并且向右眼像素R写入与右眼图像对应的数据信号，而在显示面板1的行方向上交替显示左眼图像和右眼图像。在这种情况下，通过人眼追踪单元识别观看所述显示面板的人的人眼的位置信息，并将人眼的位置信息发送给MEMS反光镜2，该MEMS反光镜2根据识别的人眼的位置信息进行旋转，以调整照射在所述MEMS反光镜2上的光的出射方向，使得通过所述显示面板1中的左眼像素L出射的光线入射至人的左眼，通过所述显示面板1中的右眼像素R出射的光线入射至人的右眼，以形成3D显示画面。另外，利用MEMS反射镜来调整光线的出射方向能够使得观察者在多个位置(视点1至视点n)都拥有较好的3D观测效果，且由于不用分别为各视点分配像素，因此不会损失分辨率。简而言之，根据本公的实施例的反射式3D显示装置功耗低、且能够提供灵活视点。
本公开的实施例还提供了一种反射式3D显示装置的显示方法，该反射式3D显示装置为上述实施例中的任意一种显示装置。该显示方法具体包括：控制显示面板1中的左眼像素L显示左眼图像，右眼像素R显示右眼图像；通过人眼追踪单元识别观看所述显示面板的人的人眼的位置信息；以及根据人眼的位置信息控制MEMS反光镜2进行旋转，调整照射在MEMS反光镜2上的光 的出射方向，使得通过显示面板1中的左眼像素L出射的光线入射至人的左眼，通过显示面板1中的右眼像素R出射的光线入射至人的右眼，以形成3D显示画面。
具体地，当本公开的实施例中的反射式3D显示装置采用如下显示装置时，即在多个MEMS反光镜2包括第一MEMS反光镜21和第二MEMS反光镜22且每个第一MEMS反光镜21与每个左眼像素L对应设置、每个第二MEMS反光镜22与每个右眼像素R对应设置的情况下，根据人眼的位置信息控制MEMS反光镜2进行旋转以调整照射在MEMS反光镜2上的光的出射方向使得通过显示面板1中的左眼像素L出射的光线入射至人的左眼、通过显示面板1中的右眼像素R出射的光线入射至人的右眼以形成3D显示画面包括：根据人眼追踪单元所采集的人的左眼位置信息控制每个第一MEMS反光镜21进行旋转，以调整照射在每个第一MEMS反光镜21上的光的出射方向，使得光线具有指向性并通过左眼像素L出射后入射至人的左眼，以在左眼中形成左眼图像；以及根据人眼追踪单元所采集的人的右眼位置信息控制每个第二MEMS反光镜22进行旋转，以调整照射在每个第二MEMS反光镜22上的光的出射方向，使得光线具有指向性并通过右眼像素R出射后入射至人的右眼，以在右眼中形成右眼图像。
之后，大脑对左眼图像和右眼图像进行分析处理和合成，从而实现裸眼3D显示。
当本公开的实施例中的反射式3D显示装置采用如下显示装置时，即在多个MEMS反光镜2包括第一MEMS反光镜21和第二MEMS反光镜22且多个第一MEMS反光镜21与每个左眼像素L对应设置、多个第二MEMS反光镜22与每个右眼像素R对应设置的情况下，根据人眼的位置信息控制MEMS反光镜2进行旋转以调整照射在MEMS反光镜2上的光的出射方向使得通过显示面板1中的左眼像素L出射的光线入射至人的左眼、通过显示面板1中的右眼像素R出射的光线入射至人的右眼以形成3D显示画面包括：根据人眼追踪单元所采集的不同的左眼位置信息控制 多个第一MEMS反光镜21中的每个进行旋转，以调整照射在所述多个第一MEMS反光镜21中的每个上的光的出射方向，使得光线具有不同的指向性并通过左眼像素L出射后入射至不同的左眼，以在不同的左眼中形成左眼图像；以及根据人眼追踪单元所采集的不同的右眼位置信息控制多个第二MEMS反光镜22中的每个进行旋转，以调整照射在所述多个第二MEMS反光镜22中的每个上的光的出射方向，使得光线具有不同的指向性并通过右眼像素R出射后入射至不同的右眼，以在不同的右眼中形成右眼图像。
之后，每个人的大脑对左眼图像和右眼图像进行分析处理和合成，从而实现供多人观看的裸眼3D显示。
当本公开的实施例中的反射式3D显示装置采用如下显示装置时，即在MEMS反光镜2为多个、多列像素划分为多个像素组、每个像素组包括相邻设置的一个左眼像素L和一个右眼像素R且每个MEMS反光镜2与每个像素组对应设置的情况下，控制显示面板1中的左眼像素L显示左眼图像、右眼像素R显示右眼图像包括：在第一时刻向显示面板1中的左眼像素L写入与左眼图像对应的数据信号，以形成左眼图像，以及在第二时刻向显示面板1中的右眼像素R写入与右眼图像对应的数据信号，以形成右眼图像。相应地，根据人眼的位置信息控制MEMS反光镜2进行旋转以调整照射在MEMS反光镜2上的光的出射方向使得通过显示面板1中的左眼像素L出射的光线入射至人的左眼、通过显示面板1中的右眼像素R出射的光线入射至人的右眼以形成3D显示画面包括：在第一时刻，根据人眼追踪单元所采集的人的左眼位置信息控制每个MEMS反光镜进行旋转，以调整照射在每个MEMS反光镜上的光的出射方向，使得通过左眼像素L出射的光线入射至人的左眼，以在左眼中形成左眼图像；以及在第二时刻，根据人眼追踪单元所采集的人的右眼位置信息控制每个MEMS反光镜进行旋转，以调整照射在每个MEMS反光镜上的光的出射方向，使得通过右眼像素R出射的光线入射至人的右眼，以在右眼中形 成右眼图像。
之后，大脑对左眼图像和右眼图像进行分析处理和合成，从而实现裸眼3D显示。
需要说明的是，本公开中的“行”和“列”仅为示例说明，在观看者与显示装置的相对位置旋转等情况下，所述“行”和“列”可对调。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的实质的情况下，可以做出各种变型和改进，这些变型和改进也视为落入本公开的保护范围。
