实施本发明的方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
通常人在真实场景中观看物体时，两眼到物体的视线夹角与晶状体屈光程度需要根据两眼与不同观察物体之间的距离与角度的不同而发生实时变化，并 且视线夹角方向与晶状体屈光程度一致，即最终被人眼捕捉到的是观察物体的光场信息。为了实现类似于真实场景中的观看体验，本申请实施例提出的显示模组、头戴式显示设备及图像立体显示方法和装置可以使得用户在虚拟场景中也能实现脑眼协调的观看体验，也可以在AR(Augmented Reality，增强现实技术)/MR(Mixed Reality，混合现实)场景中实现虚拟物体与真实物体的同视距叠加，提升用户的观看体验。
图1为本申请实施例提供的显示模组的电连接示意图。图2为本申请实施例提供的显示模组中显示屏与液晶透镜层的结构及光学成像示意图。如图1所示，显示模组包括显示屏1、液晶透镜层2及控制模块3。如图2所示，显示屏1包含多个像素组10，各像素组10内包含至少一颗像素。像素是显示屏的最小发光单位，显示屏中的每一个可被单独控制的发光单元称为像素。液晶透镜层2可以包括多个液晶透镜单元20，各像素组10均对应设置有液晶透镜单元20。液晶透镜单元20包括液晶分子。结合图1所示，控制模块3电连接于显示屏1及液晶透镜层2，用于获取所述显示屏1上各像素组10待显示内容的虚拟显示深度信息，在各像素组10显示所述待显示内容后，根据该虚拟显示深度信息控制各像素组10对应的液晶透镜单元20中的液晶分子所处的电场，以改变所述对应的液晶透镜单元20的折射率，进而，通过所述对应的液晶透镜单元调整各像素组所显示内容的第一虚像。其中，所述虚拟显示深度信息为所述待显示内容中各物体的距离信息。即，控制模块3能够根据像素组10所显示内容中包括的各物体的距离信息控制像素组10对应的液晶透镜单元20中液晶分子所处的电场，以改变所述液晶透镜单元20的折射率，进而调整对应所述像素组10所显示内容的虚像的虚像距。
图3为本申请实施例提供的液晶透镜层的光学成像示意图，图4为本申请实施例提供的液晶透镜层的液晶透镜单元的光学成像示意图。参见图3及图4所示，在液晶透镜(Liquid Crystal Lens，简写LC lens)层2中，当控制模块3通过电极21给每组液晶透镜单元20施加不同的电场时，每组液晶透镜单元20内的液晶分子会发生不同程度的旋转，形成不同的折射率，从而使得每组液晶透镜单元20形成具有不同汇聚能力的微小透镜。由于控制模块3所包括的微 小的电极产生电场使得液晶分子偏转，从而产生聚焦作用，使得液晶透镜单元20形成与其对应的像素组10所显示内容的放大的虚像。通常的透镜原理是在同种折射率下，利用镜面的曲率造成光线偏转，而本申请实施例的液晶透镜层2可以在同样厚度的情况下，利用在液晶透镜层2的不同区域的折射率不同造成光线偏转。
根据放大镜原理，当物体所在平面，即物面，处于透镜的一倍焦距以内时，会在物体同侧形成物体的放大虚像，虚像距离观看者的距离即为虚像距。结合图2所示，显示屏1的像素组10位于液晶透镜单元20的一倍焦距内时，位于显示屏1出光侧的观看者能够看到像素组10所显示内容在液晶透镜单元20同侧形成的第一虚像101。
控制模块3改变液晶透镜单元20的电场，能够使液晶透镜单元20内的液晶分子发生旋转。控制模块3通过给不同的液晶透镜单元20施加不同的电场，使得不同的液晶透镜单元20的液晶分子的旋转角度不同，从而使得多个液晶透镜单元20能够实现对其对应像素组10的光线不同的折射效果，进而使得对应像素组10所显示内容所成的多个第一虚像101具有不同的虚像距。
多个像素组10所显示的内容分别通过液晶透镜单元20成像在不同的虚像距位置处。如图2所示，显示屏距离观看者的距离是一定的(未示出)，两个像素组10所显示内容分别所成的第一虚像101在距离显示屏的d1和d2位置处。这样，观看者透过液晶透镜层2即可看到显示屏1所显示内容为立体效果。各像素组10所显示内容变化时，控制模块3可以控制相应的液晶透镜单元20的折射率变化进而改变对应的像素组10所显示内容的虚像的虚像距，使得各像素组10所显示内容的虚像的虚像距可以实时根据所显示内容进行变化，观看者可以实时观看到相应的立体效果，避免了眩晕不适，提高用户体验。
图5为本申请实施例提供的显示模组的结构及光学成像示意图。进一步，如图5所示，显示模组还可以包括观看透镜4，液晶透镜层2位于显示屏1与观看透镜4之间，观看透镜4位于用户和液晶透镜层2之间。本申请实施例中，观看透镜4为一凸透镜。显示屏1所显示的内容位于液晶透镜层2的一倍焦距以内，通过液晶透镜层2形成的显示屏1所显示内容的第一虚像101位于 观看透镜4的一倍焦距以内，使得观看透镜4可以对第一虚像101进行放大形成放大的第二虚像102。
由于液晶透镜层2的微小折光性，使得原本位置的像素组10所显示内容一次成像形成的第一虚像101位于与显示屏1相距为d的位置处。距离d可以非常小，在毫米mm级别。通过设置观看透镜4，将液晶透镜层2与显示屏1均设置在观看透镜4的一倍焦距以内，靠近一倍焦距附近，经液晶透镜层2一次成像形成的第一虚像101可以位于观看透镜4的一倍焦距以内，靠近一倍焦距附近。即第一虚像101与观看透镜4之间的距离D2接近观看透镜4的焦距。所以一次成像形成的第一虚像101的微小变化都可以导致其通过观看透镜4二次成像后的第二虚像102变化非常大，二次成像后形成的第二虚像102至观看透镜4之间的距离D会因为D2的微小变化而发生非常显著的变化。例如，当观看透镜4的焦距在30mm附近时，D2的变化为1mm就能使二次虚像至观看透镜之间的距离D变化超过10m。通过观看透镜4可以使得二次成像的第二虚像的位置发生显著变化，从而实现当观看者透过观看透镜4观看平面的显示屏1时，却能看到每个像素组所显示内容有不同的距离，即看到立体图像画面。
显示屏1与液晶透镜层2可以贴合设置，以方便二者之间的装配连接，使得各像素组10与液晶透镜单元20之间的距离均相等，利于对成像的控制；同时可以使得显示屏1与液晶透镜层2之间没有间隙，避免灰尘等杂物的进入。显示屏1与液晶透镜层2贴合设置，可以尽可能减小二者之间的距离，使得液晶透镜单元20的折射率改变至焦距最小时，像素组10依然位于液晶透镜单元20的一倍焦距以内。
显示屏1的显示区域面积可以小于或等于液晶透镜层2的面积，液晶透镜层2的边缘延伸至显示屏1的显示区域之外，可以保证显示屏1上每个像素组10均对应设置有液晶透镜单元20。同时，液晶透镜层2的面积大于显示屏1的显示区域面积，可以便于对液晶透镜层2的液晶透镜单元20与显示屏1的像素组10之间的校准。例如，当被控制的液晶透镜单元20与对应的像素组10之间的对应发生错位时，用户可以对液晶透镜单元20进行移动，控制所有液晶透镜单元20进行左右或上下移动，此时，依然可以保证所有像素组10均依然对应有液晶透镜单元20。
在通过电极施加电压时，液晶透镜单元20内的多个液晶分子排布可以呈矩阵状或排布呈依次嵌套的多环状。
如图4所示，每个液晶透镜单元20可以设置有用于控制电场的两个电极21，所述两个电极21沿观看者的左右方向排布。两个电极21分别为正电极和负电极。通过改变对两个电极21所施加的电压，可以改变液晶透镜单元20内液晶分子所处的电场，从而改变液晶透镜单元20的折射率。两个电极21沿观看者的左右方向排布，可以与观看者左右眼形成最佳视觉效果。
根据本申请实施例，液晶透镜层也可以包含许多像素。每个液晶透镜单元20包含至少一颗像素。所述电极在给液晶透镜单元20施加电压时，是施加在液晶透镜单元20所包含的像素上，控制像素的开关及灰阶。人们肉眼所见的液晶屏幕的每一个点，即一个像素，是由红、绿、蓝(RGB)三个子像素组成的。每一个子像素，其背后的光源都可以显现出不同的亮度级别。灰阶代表了由最暗到最亮之间不同亮度的层次级别，层级越多，所能够呈现的画面效果也就越细腻。不同亮度层次的红、绿、蓝组合起来，最终形成不同色彩的点。
根据本申请实施例，由于控制模块3是根据像素组10所显示内容中包括的各物体的距离信息控制像素组10对应的液晶透镜单元20中液晶分子所处的电场，以改变液晶透镜单元20的折射率，进而调整对应的像素组10所显示内容的的虚像的虚像距，因此，可以在虚拟场景搭建或生成时，例如在通过虚拟引擎Unity设计虚拟现实游戏或者拍摄虚拟现实电影时，将虚拟现实游戏场景中或者虚拟现实电影场景中的待由显示屏1的每个像素组10显示的物体与摄像头之间的距离信息记录下来。之后在用户在体验所述虚拟现实游戏或虚拟现实电影时，图像立体显示装置，例如，头戴式显示设备，获取所述虚拟现实游戏或者虚拟现实电影中记录的物体与摄像头之间的距离，按照该距离将所对应的物体的虚像呈现出来。
根据本申请实施例，在虚拟现实游戏中，物体与摄像头之间的距离可以通过计算虚拟现实游戏中的虚拟摄像头与虚拟物体之间的距离得到。在虚拟现实电影的情况下，可以在拍摄虚拟现实电影时，通过可以感知距离的摄像头获得物体与摄像头之间的距离。
例如，在设计一个虚拟现实游戏时，该虚拟现实游戏场景中存在第一物体和第二物体，第一物体与第二物体距离观看者的距离(也即第一物体与第二物 体距离虚拟现实游戏场景中的虚拟摄像头的距离)分别为第一距离、第二距离。第一距离和第二距离作为距离信息与物体的其他信息(例如，颜色、亮度、纹理等)一起被记录和存储。所述距离信息即为虚拟显示深度信息。在虚拟现实电影的情况下，所述距离信息可以作为虚拟现实画面中的像素点的信息存储。
在进行虚拟成像时，例如观看者通过头戴式显示设备体验所述虚拟现实游戏，头戴式显示设备中显示屏1的两个像素组10分别呈现第一物体和第二物体的影像时，控制模块3从所述虚拟现实游戏的数据中获得所述第一物体和第二物体的虚拟显示深度信息，并根据虚拟显示深度信息，分别给与所述两个像素组对应的两个液晶透镜单元20施加相应的电场，控制与两个像素组相对应的两个液晶透镜单元20的折射率，以将第一物体和第二物体的影像根据各自虚拟显示深度信息以预设的比例进行虚拟成像，形成两个第一虚像101，再通过观看透镜4对两个第一虚像101进行再次虚拟成像，形成两个第二虚像102。根据本申请实施例，控制模块3中可以预先设置有液晶透镜单元的折射率与电压之间的对应关系，在进行虚拟成像时，根据该预先设置的对应关系控制液晶透镜单元20的折射率。两个第二虚像102的虚像距分别与第一距离和第二距离相等，使得观看者看到的两个物体的两个第二虚像102的位置与两个物体在虚拟现实游戏场景中的位置相同。这样一来，观看者在观看时就可以实现和在真实场景中自由观看不同景物时一致的体验，即不同的物体可能有不同的距离。
图6是本申请实施例提供的显示模组的结构及成像示意图。在前面实施例中，通过观看透镜4对液晶透镜层所成的第一虚像进行二次成像形成第二虚像102，第二虚像102即为观看者可以观看到的虚像。根据本申请实施例，由于液晶透镜层2的响应速度与激发电压都与自身厚度相关，为了提高液晶透镜层的响应速度，并且节省液晶透镜材料，如图6所示，可以在液晶透镜层2上再叠加一层透镜阵列层2a。透镜阵列层2a包括阵列排布的多个凸透镜20a，每个所述凸透镜20a对应设置至少一个所述液晶透镜单元。每个凸透镜20a可以分别对应设置至少一个液晶透镜单元20，以便对至少一个液晶透镜单元20的第一虚像101进行再次成像形成过渡虚像101a。透镜阵列层2a或其所成过渡虚 像101a位于观看透镜4的一倍焦距以内，以便再次成像形成最终供观看者看到的虚像。这样，只需要很薄的一层液晶透镜层2将在与显示屏距离为d1、d2的位置处形成第一虚像101，之后通过液晶透镜单元电场的变化使显示屏中的每个像素组所显示内容的虚像位置发生微小变化，再通过透镜阵列层2a将第一虚像101再次在与显示屏距离为d3、d4的位置处形成过渡虚像101a，进而可以将距离d1、d2进行放大。最后，通过观看透镜4将过渡虚像101a进行最后的成像，形成最终可以供观看者看到的虚像，经过三次成像后的虚像相比较于一次所成的虚像发生显著变化，从而实现当用户透过观看透镜4看平面的屏幕时，却能看到每个像素组所显示内容有不同的距离，即看到立体画面图像。
进一步，在本申请实施例中，透镜阵列层为微透镜阵列层，其中的每一个凸透镜可以对应一个液晶透镜单元20，以提高成像准确度、清晰度。
本申请实施例提供的显示模组，可以应用于各类显示器或头戴显示装置中，可以适用于AR(Augmented Reality，增强现实技术)或MR(Mixed Reality，混合现实)场景中，观看者的虚拟物体与真实物体的视距相同从而提高体验感。
图7为本申请实施例提供的头戴式显示设备的结构及光学成像示意图。如图7所示，该头戴式显示设备可以包括前述各个实施例的显示模组，具体地，可以包括显示屏1、液晶透镜层2、观看透镜4。头戴式显示设备还可以包括控制模块3(未示出)。控制模块3根据显示屏1的各像素组所显示内容的虚拟显示深度信息控制液晶透镜层2的液晶透镜单元上的电压，以改变所述对应的液晶透镜单元的折射率，通过所述对应的液晶透镜单元呈现所述显示屏上各像素组所显示内容的第一虚像101，该第一虚像101通过观看透镜4形成第二虚像102。显示模组可以为两个，分别对应观看者的左右眼。图7中的各部件可以参考前文的描述。
本申请实施例还提供了一种图像立体显示方法，可以适用于前述的显示模组。图8所示为本申请实施例提供的图像立体显示方法，如图8所示，该方法主要包括以下步骤：
步骤S101、获取待在显示屏上显示的待显示图像，待显示图像包含多个像素区。
根据本申请实施例，例如显示模组获得待在显示屏上显示的图像时，从待显示的图像数据中获取待显示图像中所包含的像素的信息，按照该待显示的图像中的像素的信息，将待显示图像划分为多个像素区，分别对应于显示屏的多个像素组，以可以对每个像素区分别进行成像，使其位于距离观看者不同的虚像距处，以呈现出立体效果。待显示图像中的像素和显示屏上的像素可能不是一一对应的，可以依照相应的精度要求设置待显示图像的像素和显示屏上的像素的对应关系。
步骤S102、获取所述待显示图像中与所述显示屏上的多个像素组对应的各像素区中每一像素区所对应的虚拟显示深度信息。
根据本申请实施例，虚拟显示深度信息为像素区的虚像与观看者位置处之间的距离信息，即模拟在真实环境中物体距离观看者之间的距离的距离信息。该虚拟显示深度信息用于确定像素区的虚像的位置，即像素区对应的虚像距。虚拟显示深度信息可以在生成或搭建虚拟场景时，记录在待显示图像的数据中，以当通过用显示模组显示虚拟场景时，同时获取待显示图像及其虚拟显示深度信息。
根据本申请实施例，在虚拟场景搭建或生成时，需要将物体的距离信息记录下来，形成对应的虚拟显示深度信息。所述物体的距离信息可以在拍摄时测量出。例如在摄影设备中设置一距离测量设备，在拍摄虚拟场景的过程中通过距离测量设备测量所拍摄的每一幅画面中物体距离摄影设备的距离，从而记录下物体对应的虚拟显示深度信息。
根据本申请实施例，待显示图像包括左眼显示图像及右眼显示图像，左眼显示图像包含多个左眼像素区，右眼显示图像包含多个右眼像素区，虚拟显示深度信息根据相对应的左眼像素区及右眼像素区分析计算得出。通常左眼显示图像及右眼显示图像分别由观看者的左眼及右眼观看，从而看到立体画面。可以根据左眼显示图像及右眼显示图像在同一位置处相对应的左眼像素区和右眼像素区二者之间差异计算出该处的虚拟显示深度信息。例如，通过双目视觉三角测量法来计算。
根据本申请实施例，显示屏的待显示图像为计算机制作的虚拟场景时，在虚拟场景进行制作时即标注出每个像素组所显示内容所在的位置，从而可以标记出每个像素组所显示内容与观看者位置之间的距离，即每个像素区的虚拟显示深度信息。
步骤S103，在显示屏上显示出所述待显示图像之后，根据所述多个像素区中每一像素区对应的所述虚拟显示深度信息，控制每一像素区对应的像素组所对应的在所述显示屏的出光方向上的液晶透镜单元中的液晶分子所处的电场，以改变所述对应的液晶透镜单元的折射率，进而，通过所述对应的液晶透镜单元调整各像素组所显示内容的第一虚像。
根据本申请实施例，在显示屏1上显示出待显示图像，显示屏1包括多个像素组10，多个像素组10与多个像素区一一对应。其中，多个像素组10中每一像素组10的出光方向设置有液晶透镜单元20。每个像素组10对应一个液晶透镜单元20。所有的液晶透镜单元20可以形成液晶透镜层2，并设置在显示屏1的出光面处。液晶透镜单元20可以对对应的像素组10所显示出的像素区进行成像。像素区即为对应像素组10所显示内容。
根据多个像素组中每一像素组10对应的虚拟显示深度信息，显示模组调整液晶透镜单元20中液晶分子所处电场，以改变液晶透镜单元20的折射率，进而使调整后的多个像素区中每一像素区按预设比例成像在预设位置处。预设位置例如为图5所示的距离d，与前述相同，距离d可以非常小，可以在10mm以内。
在所述液晶透镜层2远离所述显示屏1的一侧设置观看透镜4，液晶透镜层2与显示屏1可以位于观看透镜4的一倍焦距内，通过观看透镜4生成供观看者观看的显示屏1所显示内容的虚像。
例如在前述第一种显示模组的实现方式中，例如如图5所示的方式，液晶透镜层2上未设置有透镜阵列层2a，所述观看透镜4可以使位于所述预设位置处的第一虚像101成像在二次预设位置处，形成第二虚像102，所述二次预设位置相对所述预设位置远离所述显示屏1。
通过观看透镜4，将液晶透镜层2与显示屏1均设置在观看透镜4的一倍焦距之内，靠近一倍焦距附近，经液晶透镜层2一次成像形成的第一虚像可以位于观看透镜4的一倍焦距附近，使得二次成像的第二虚像的位置发生显著变 化，从而实现当观看者透过观看透镜4观看平面的显示屏1时，却能看到每个像素组对应的画面有不同的距离，即看到立体图像画面。
二次预设位置与对应虚拟显示深度信息所标记的位置相同或者近似相同，用户在观看时就可以实现和在真实场景中自由观看不同景物时一致的体验，实现类似于真实场景中的观看体验，可以使得用户在虚拟场景中也能实现脑眼协调的观看体验。
在前述第二种显示模组的实施方式中，例如如图6所示的方式，液晶透镜层2上设置有透镜阵列层2a，透镜阵列层2a可以对液晶透镜层2形成的第一虚像101进行第二次成像形成过渡虚像101a，过渡虚像101a经观看透镜4进行第三次成像后可以形成最终被观看者看到的虚像。经过三次成像后的虚像发生显著变化，从而实现当用户透过观看透镜看平面的屏幕时，却能看到每个像素组所显示内容有不同的距离，即看到立体画面图像。
本申请实施例中，液晶透镜层2可以使每个像素组10所显示的像素区发生第一次成像，利用液晶透镜层2的折射率变化使得各个像素组10所显示的像素区的第一虚像发生10mm以内的微小变化，再通过观看透镜4对第一虚像进行最后一次成像形成供观看者看到的虚像，观看透镜4形成的虚像的虚像距可以将前述微小变化放大，使得最终成像的虚像距与实际拍摄距离大致相同，实现类似于真实场景中的观看体验。
本申请实施例中多个像素组所显示的内容分别通过液晶透镜单元成像在不同的虚像距位置处，观看者透过液晶透镜层即可看到显示屏所显示内容为立体效果，各像素组所显示内容变化时，控制模块可以控制相应的液晶透镜单元的折射率变化进而改变所显示内容的虚像距，使得虚像距可以实时根据所显示内容进行变化，观看者可以实时观看到相应的立体效果，避免了眩晕不适，提高用户体验。
