本技术领域技术人员可以理解，除非另外定义，这里使用的所有术语(包括技术术语和科学术语)，具有与本公开实施例所属领域中普通技术人员的一般理解相同的意义。还应该理解的是，诸如通用字典中定义的那些术语，应该被理解为具有与现有技术的上下文中意义一致的意义，并且除非像这里一样被特定定义，否则不会用理想化或过于正式的含义来解释。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。应该进一步理解的是，本公开实施例的说明书中使用的措辞“包括”是指存在所述特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
本公开实施例提供了一种立体显示装置。图1为本公开实施例提供的一种立体显示装置的结构示意图，图2为本公开实施例提供的旋转轴与多个显示组件装配后的俯视图，图3为本公开实施例提供的图2中一个显示组件的主视图，以及图4为本公开实施例提供的图2中一个显示组件的侧视图。
如图1至图4所示，立体显示装置包括旋转轴2和至少一个显示组件100。显示组件100固定于旋转轴2，显示组件100包括至少三个显示面，至少一个显示面被配置为沿旋转轴2的径向背对旋转轴2。
显示面可以为图2中的第一显示面501、第二显示面502或第三显示面503。如图2所示，第二显示面502被配置为沿旋转轴2的径向背对旋转轴2。
应当说明的是，三维图像需要在一个空间体中显示，空间体需要包括多个立体像素，若干立体像素发光形成三维图像。在本公开实施例中，一个显示面在旋转时在空间中扫掠形成空间体，显示面中的每个平面像素在每个预设位置都可以被看作是一个立体像素。例如，显示面旋转一周的过程中经过10个预设位置，则每个平面像素都可以形成10个立体像素。显示面用于显示二维图像，二维图像由多个发光的像素组成。在到达某一预设位置时，显示面中每个发光的像素都被看作是一个发光的立体像素，由于一个立体显示装置可以设置至少一个显示组件100，同时一个显示组件100包括至少三个显示面，这就形成了较多数量的立体像素，多个发光的立体像素构成一帧三维图像。
应当说明的是，在本公开实施例中，相位表示部件的旋转角度。将所有的显示面看作一个部件，预先选择至少一个特定的角度(如90度、180度、270度和360度)以及一个特定的显示面，当该显示面旋转到特定的角度时，即表示所有的显示面到达预设相位，也表示显示面到达预设位置。在一个旋转周期(旋转360度)中，可以设置至少一个预设相位。
旋转轴22能够带动多个显示组件100转动，每到达一次预设位置，多个显示面就可以显示一帧三维图像。当显示面板55以较快的速度旋转时，用户可以在视觉停留的时间内观看到多帧三维图像，从而观看到具有立体效果的图像。应用该立体显示装置时，用户观察者无需佩戴3D眼镜，可以裸眼观看到具有立体效果的图。而且，用户的观看距离和观看角度不受限制，可以在360度中的任意位置观看。
一种显示组件100只设置一个或两个显示面，且显示面的设置在垂直于显示组件100的厚度方向。因此在不增加显示组件100的体积的情况下，难以再增加较多的显示面的面积，这就导致单个显示组件100所能产生的体素数量较少，从而影响显示效果。
本公开实施例的发明人发现，对于安装在旋转轴2上的显示组件100，当显示组件100经过用户时，显示组件100的一个平行于其厚度方向的侧面是正对用户的视线的。如果将该侧面配置为显示面，则可以显著地增加显示组件100所能产生体素的数量，有助于提升显示效果。该新增加的显示面设置为在显示装置中沿旋转轴2的径向背对旋转轴2。
在旋转速度不变的前提下，由于显示组件100至少包括三个显示面，且每个显示面有多个平面像素，单位时间内可以产生更多数量的立体像素，提高单位时间内显示的三维图像的帧数，有助于增强显示效果。在三维图像自身的体素数量不变的前提下，可以进一步地提高显示组件100转速，有助于提高刷新率，也有助于增强显示效果。
另外，在一种立体显示装置中，由于显示组件100的平行于其厚度方向的侧面是正对用户的视线，且该侧面不用于显示图像，当侧面出现在用户视野中会影响用户的观看体验。在本公开实施例中的立体显示装置中，将平行于显示组件100的厚度方向的侧面配置为显示面，该显示面用于显示图像，由此避免了上述侧面对用户的视觉干扰，同时可以增强显示效果。
例如，在本公开实施例提供的立体显示装置中，如图2所示，至少三个显示面包括依次连接的第一显示面501、第二显示面502和第三显示面503。第一显示面501和第三显示面503与旋转轴2连接。第二显示面502与旋转轴2之间具有间隔，且沿旋转轴2的径向背对旋转轴2。
第一显示面501和第三显示面503大致垂直于显示组件100的厚度方向，第二显示面502大致平行于显示组件100的厚度方向。例如，旋转轴22上可以设置夹具，通过夹具将显示组件100固定在旋转轴22上。
例如，在本公开实施例提供的立体显示装置中，如图3所示，第一显示面501与旋转轴2之间的夹角为第一角度，第三显示面503与旋转轴2之间的夹角为第二角度，第一角度和第二角度中的至少一个的范围为0度至10度之间。
以图3为例，图中虚线L表示旋转轴2的轴线，角A表示第一显示面501与旋转轴2之间的夹角，角B表示第三显示面503与旋转轴2之间的夹角。应当说明的是，虚线L并不指示旋转轴2的轴线的实际位置，仅仅是为了清楚地表示夹角而对轴线进行平移。
如图3所示，第一显示面501和第三显示面503相向偏转，因此使得第二显示面502呈梯形。例如，第一角度与第二角度相等，则第二显示面502为等腰梯形。
例如，在本公开实施例提供的立体显示装置中，如图4所示，第二显示面502与旋转轴2之间的夹角为第三角度，第三角度的范围为0度至10度之间。
如图4所示，图中虚线L表示旋转轴2的轴线，角C表示第二显示面502与旋转轴2之间的夹角。应当说明的是，虚线L并不是旋转轴2的轴线的实际位置，仅仅是为了清楚地表示夹角而对轴线进行平移。
在图中4，由于第二显示面502相对于旋转轴2偏转，因此使得第三显示面503呈梯形，第二显示面502也呈梯形。
在本公开实施例提供的立体显示装置中，由于显示面与旋转轴2的轴向成角度，当显示组件100转动时具有风扇效应，风扇效应形成的气流将显示组件100产生的温度带出，从而为显示组件100降温，使得显示组件100保持良好的性能。
例如，如图1所示，本公开实施例提供的立体显示装置还包括外壳6。外壳6环绕在多个显示组件100的外侧，外壳6具有第一开口61和第二开口62，第一开口61和第二开口62沿旋转轴22的轴向正对。外壳6可以由透明材质制作而成。
在图1中，外壳6为两端开口且具有预设长度的筒状，第一开口61和第二开口62位于外壳6长度方向的两端。
显示组件100转动时具有风扇效应，空气从外壳6的第一开口61进入外壳6，再由第二开口62流出外壳6，形成流速较高的气流，将显示组件100的温度带出外壳6，从而为显示组件100降温，使得显示组件100保持良好的性能。
例如，在本公开实施例提供的立体显示装置中，显示组件100包括至少三个显示面板5，至少三个显示面板5与至少三个显示面一一对应。
以图2中最下方的显示组件1001为例，显示面板5A包括第一显示面501，显示面板5B包括第二显示面502，显示面板5C包括第三显示面503。
立体显示装置中显示组件100的数量以及相邻两个显示组件100之间的夹角可以根据实际需要而定。如图2所示，本公开实施例提供的立体显示装置包括4个显示组件100，相邻两个显示组件100之间成90度角。
显示组件100中显示面板5的数量可以根据实际的设计需要而定。如图2和图4所示，显示组件1001、1002、1003和1004各自包括三个显示面板。以图2中的显示组件1001为例，在该显示组件1001的三个显示面板5A、5B和5C中，第一个显示面板5A的显示面和第三个显示面板5C的显示面沿旋转轴2的周向相背对。第三个显示面板5C显示面分别第一个显示面板5A的显示面和第二个显示面板5B的显示面相邻接。
如图2和图3所示，显示组件100呈板状。图2第一个显示面板5A的和第二个显示面板5B沿显示组件1001的厚度方向间隔设置，显示组件1001的三个显示面板5A、5B和5C围合成U形结构，U形结构的开口正对旋转轴2的周面。第一个显示面板5A的显示面和第三个显示面板5C的显示面为显示组件1001中大致垂直于厚度方向的侧面。第二个显示面板5B的显示面为显示组件1001中大致平行于厚度方向的侧面。
例如，显示组件100包括柔性显示面板，柔性显示面板弯折后形成至少三个显示区域，每个显示区域对应一个显示面。例如，将柔性显示面板弯折两次后形成三个显示区域，三个显示区域分别对应第一显示面501、第二显示面502和第三显示面503。
例如，如图1和图6所示，根据本公开实施例的立体显示装置还包括：驱动装 置1，与旋转轴2传动连接。角度采集装置3设置于旋转轴2，检测旋转轴2的旋转角度信息。信息处理装置4与角度采集装置3电连接，在根据旋转角度信息确定显示面板5处于预设相位时，将第N帧三维图像数据转换为多个第N帧二维图像数据并存储，并从已存储的多个第N-1帧二维图像数据中，确定每个显示面板5要显示的二维图像数据并发送。
显示面板5与信息处理装置4电连接，用于接收第N-1帧二维图像数据并存储，以及根据已存储的第N-2帧二维图像数据进行显示。N为大于2的正整数。
驱动装置1驱动旋转轴2转动，旋转轴2能够带动多个显示组件转动，从而使得显示面板5转动。在同一时间段内旋转轴2和每个显示面板5转过的角度时相同的，检测旋转轴2的旋转角度信息包括检测每个显示面板5的旋转角度信息。在本公开实施例中，可以当旋转轴2每转过一个预设角度(如10度)，信息处理装置4即确定所有的显示面板5都处于一个预设相位。例如，该预设角度可以是0度至360度中的任一数值，具体取值可以根据实际的设计需要而定。
三维图像数据为原始的显示信号，一帧三维图像数据包括了一帧三维图像的所有显示信息。信息处理装置4用于将一帧三维图像转换为多个二维图像数据，一个二维图像数据包括了一个二维图像的所有显示信息，每个显示面板5显示根据对应的二维图像数据进行显示二维图像。
一帧三维图像数据转换出的二维图像数据的数量可以根据所需要的显示面板5的数量而定。在本公开实施例中，显示组件100包括12个显示面板5，因此一帧三维图像数据可以转换为12个二维图像数据。
例如，在图1中，旋转轴2设置上有角度采集装置3。角度采集装置3可以是角度传感器或轴编码器。
例如，驱动装置1为电机，电机的输出轴与旋转轴2连接。或者，电机的输出轴通过减速装置与旋转轴2连接。
例如，在本公开实施例提供的立体显示装置中，如图6所示，信息处理装置4可以包括第一控制单元41、同步信号单元42和第一存储单元43。
第一控制单元41分别与同步信号单元42、第一存储单元43和显示面板5电连接。
同步信号单元42与角度采集装置3电连接，用于在根据旋转角度信息确定显示 面板5到达预设相位时，发送同步信号。
第一控制单元41用于在接收到同步信号时，将第N帧三维图像数据转换为多个第N帧二维图像数据并存储到第一存储单元43中，以及从已存储的多个第N-1帧二维图像数据中，确定每个显示面板5要显示的二维图像数据并发送。
例如，在本公开实施例提供的立体显示装置中，如图6所示，信息处理装置4还包括第一数据分发单元44。第一控制单元41的输出端与第一数据分发单元44的输入端电连接，第一数据分发单元44的输出端与各显示面板5电连接。
本领域技术人员可以理解，第一控制单元41、同步信号单元42和第一数据分发单元44均为功能模块。其功能均可以由信息处理装置4来实现。
第一控制单元41将第一存储单元43已存储的多个第N-1帧二维图像数据向第一数据分发单元44发送，使得第一数据分发单元44根据预设的地址对应关系，将接收到的每个第N-1帧二维图像数据向多个显示面板5之一发送。
例如，在本公开实施例提供的立体显示装置中，如图6所示，显示面板5包括第二控制单元51、第二存储单元52以及发光单元。发光单元包括显示面。本领域技术人员可以理解，第二控制单元51为功能模块。其功能可以由处理器来实现。
第二控制单元51分别与第二存储单元52、发光单元、第一控制单元41和同步信号单元42电连接。
第二控制单元51用于接收到同步信号时，接收第N-1帧二维图像数据，并存储在第二存储单元52中，以及将第二存储单元52中已存储的第N-2帧二维图像数据，向发光单元发送，使得发光单元进行显示。
同步信号单元42在根据旋转角度信息确定显示面板5到达预设相位时，同时向第一控制单元41和第二控制单元51发送同步信号。例如，第二控制单元51通过第一数据分发单元44与第一控制单元41电连接。例如，第二控制单元51的输入端与第一数据分发单元44的输出端电连接。
例如，在本公开实施例提供的立体显示装置中，如图5和图6所示，发光单元包括多个显示子单元54，第二控制单元51与多个显示子单元54电连接。
第一控制单元41根据第N帧子三维图像数据，确定显示面板5的每个显示子单元54的子二维图像数据，并存储在第一存储单元43中，以及将第N-1帧三维图像数据对应的每个显示面板5中待各显示子单元54显示的子二维图像数据，向对应 的显示面板5发送。
第二控制单元51接收第N-1帧三维图像数据对应的每个显示面板5中各显示子单元54要显示的子二维图像数据，并存储在第二存储单元52中；以及将第二存储单元52中已存储的每个第N-2帧子二维图像数据，向发光单元中对应的显示子单元54发送。
每个显示子单元54可以被看作是显示面板5的一个平面像素，一个二维图像由多个发光的显示子单元54形成。一个子二维图像数据包括了一个显示子单元54的显示信息。子二维图像数据可以包括显示子单元54的发光亮度、发光时长和发光颜色等信息。本领域的技术人员可以理解，发光亮度包括亮度为零，即显示子单元54不发光。
在本公开实施例提供的立体显示装置中，越靠近旋转轴2，显示子单元54的密度越大。当所有的显示子单元54的发光亮度相同时，从用户的视角看，用户所感知到的靠近旋转轴2的区域的亮度大于远离旋转轴2的区域的亮度，这会导致用户感知到的三维图像出现明暗不均的现象。
根据本公开实施例，每个显示子单元54发光亮度可以独立调节。为此，可以如下设置显示子单元54的发光亮度：显示子单元54距离旋转轴2越近，则发光亮度越低。这使得用户所感知到的各区域的显示子单元54发光亮度大致是相同的，降低了三维图像中明暗不均的现象的程度，提升用户的观看体验。
二维图像数据划分的子二维图像数据的数量可以根据所需要的显示子单元54的数量而定。例如，一个显示面板5包括100个显示子单元54，因此一个二维图像数据可以转换出100个子二维图像数据。
例如，在本公开实施例提供的立体显示装置中，显示面板5还包括第二数据分发单元53。第二控制单元51的输出端与第二数据分发单元53的输入端电连接，第二数据分发单元53的输出端与发光单元中每个显示子单元54的输入端电连接。
第二控制单元51将第二存储单元52中已存储的第N-2帧的每个子二维图像数据向第二数据分发单元53发送，使得第二数据分发单元53根据预设的地址对应关系，将接收到的每个子二维图像数据向对应的显示子单元54发送。
例如，如图7所示，显示子单元54包括驱动器件541和发光器件542。驱动器件541的输入端与第二数据分发单元53的输出端电连接，驱动器件541的输出端与 发光器件542电连接。驱动器件541接收子二维图像数据，驱动发光器件542发出预设亮度的光。应当说明的是，如果子二维图像数据中发光亮度为零，驱动器件541驱动发光器件542停止发光。
在本公开实施例提供的立体显示装置中，在处于预设相位时，信息处理装置4处理第N帧三维图像数据，而显示组件100显示第N-2帧三维图像数据对应的图像。因此数据的处理和图像的显示步骤是同时进行的，这可以避免图像的显示步骤的开始时间受数据的处理步骤的影响，保证各帧三维图像能够流畅地依次显示，防止出现延迟，提升显示效果。
本公开实施例还提供了一种立体显示装置的控制方法，该方法应用于本公开实施例提供的立体显示装置。如图8A所示，该控制方法可以包括以下步骤。
在步骤S801，根据旋转角度信息确定出显示面板处于预设相位时，信息处理装置将第N帧三维图像数据转换为多个第N帧二维图像数据。
在步骤S802，信息处理装置从已存储的多个第N-1帧二维图像数据中，确定每个显示面板5要显示的第N-1帧二维图像数据并发送。
在步骤S803，显示面板5接收显示面板5要显示的第N-1帧二维图像数据并存储，以及根据已存储的第N-2帧二维图像数据进行显示；N为大于2的正整数。
例如，信息处理装置4的同步信号单元42根据旋转角度信息确定出显示面板5到达预设相位时，发送同步信号。信息处理装置4的第一控制单元41接收到同步信号时，将第N帧三维图像数据转换为多个二维图像数据并存储。例如，可以存储在信息处理装置4的第一存储单元43中。
从已存储的多个第N-1帧多个二维图像数据中，确定出每个显示面板5待显示的二维图像数据并发送，包括：从第一存储单元43中已存储的第N-1帧三维图像数据对应的多个二维图像数据中，确定出每个显示面板5待显示的二维图像数据并发送。
例如，显示面板5接收第N-1帧三维图像数据对应的待显示面板5显示的二维图像数据并存储，包括：显示面板5的第二控制单元51接收到同步信号时，接收第N-1帧三维图像数据对应的待显示面板5显示的二维图像数据，并存储在显示面板5的第二存储单元52中。
根据已存储的第N-2帧三维图像数据对应的二维图像数据进行显示，包括：将第二存储单元52中已存储的第N-2帧三维图像数据对应的二维图像数据，向显示面板5的发光单元发送，使得发光单元进行显示。
例如，信息处理装置4在根据旋转角度信息确定出显示面板5到达预设相位之前，还根据旋转角度信息确定驱动装置1的转速是否在预设速度范围内。若驱动装置1的转速在预设速度范围内，则表明驱动装置1的转速稳定。在驱动装置1的转速稳定的前提下，信息处理装置4开始执行将三维图像数据转换为多个二维图像数据的步骤。
例如，第一控制单元41接收旋转角度信息，根据旋转角度信息确定驱动装置1的转速预设速度范围内。
本公开实施例还提供了一种立体显示装置的示例控制方法，该方法的流程示意图如图8B所示，该方法中三维图像数据的处理时序图如图9所示。该方法包括以下步骤。
在S811，第一控制单元41根据接收到的旋转角度信息确定驱动装置1的转速预设速度范闺内。
在S812，根据旋转角度信息确定显示面板5到达预设相位时，发送同步信号。
在S813，第一控制单元41响应于同步信号，将第N帧三维图像数据转换为多个二维图像数据并存储；已存储的多个第N-1帧二维图像数据中，确定每个显示面板待显示的二维图像数据并发送。
在S814，第二控制单元51响应于同步信号，接收第N-1帧二维图像数据，并存储；将已存储的第N-2帧二维图像数据，发送至发光单元以便发光单元进行显示。
例如，步骤S813和S814之间没有严格的执行顺序，可以同时执行，也可以一个先执行另一个后执行。
显示面板5处于下一个预设相位时，N值累加1，继续执行步骤S812和步骤S813。
例如，步骤S813中的一种方法的流程示意图如图10所示，可以包括以下步骤。
在S1001，第一控制单元41确定每个显示面板5处于预设相位时的空间位置。
在S1002，根据显示面板5的空间位置，确定显示面板5在第N帧三维图像数据中的立体像素。
在S1003，确定显示面板5的立体像素的第N帧子三维图像数据。
在S1004，根据第N帧子三维图像数据，确定显示面板5的二维图像数据。
例如，步骤S1004还可以包括：第一控制单元41根据第N帧子三维图像数据，确定显示面板5的每个显示子单元54的子二维图像数据，并存储在例如第一存储单元43中。
步骤S813中，第一控制单元41从第一存储单元43中已存储的多个第N-1帧二维图像数据中，确定每个显示面板5中待各显示子单元54要显示的第N-1帧子二维图像数据，并向对应的显示面板5发送。各子二维图像数据已存储在第一存储单元43中。
例如，步骤S813中，第一控制单元41将第一存储单元43已存储的第N-1帧三维图像数据对应的多个二维图像数据，向第一数据分发单元44发送。第一数据分发单元44根据预设的地址对应关系，将接收到的每个二维图像数据向对应的显示面板5发送。
例如，第一控制单元41将每个显示面板5中待各显示子单元54显示第N-1帧的子二维图像数据，向第一数据分发单元44发送；使得第一数据分发单元44根据预设的地址对应关系，将接收到的每个显示面板5中待各显示子单元54显示的子二维图像数据向对应的显示面板5发送。
例如，显示子单元54的驱动器件541接收子二维图像数据，驱动发光器件542发出预设亮度的光。应当说明的是，如果子二维图像数据中发光亮度为零，则驱动器件541驱动发光器件542停止发光。
例如，在步骤S813中，显示面板5的第二控制单元51接收到同步信号时，接收待显示面板5显示的第N-1帧二维图像数据，并存储在显示面板5的第二存储单元52中。
例如，第二控制单元51接收每个显示面板5中待各显示子单元54要显示的第N-1帧子二维图像数据，并存储在第二存储单元52中。
在步骤S813中，将第二存储单元52中已存储的第N-2帧二维图像数据向显示面板5的发光单元发送，使得发光单元进行显示。
例如，第二控制单元51将第二存储单元52中已存储的每个第N-2帧子二维图像数据，向发光单元中对应的显示子单元54发送。
第二控制单元51将第二存储单元52中已存储的每个第N-2帧子二维图像数据 向第二数据分发单元53发送，使得第二数据分发单元53根据预设的地址对应关系，将接收到的每个子二维图像数据向对应的显示子单元54发送。
第二数据分发单元53根据预设的地址对应关系，将接收到的每个子二维图像数据发送至对应的显示子单元54的驱动器件541，驱动器件541驱动发光器件542发出预设亮度的光。
