具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关 系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的机或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本公开实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“连接”、“耦接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
相关技术中裸眼3D技术主要通过三种方式实现，分别包括：光屏障式、柱面镜式和指向性背光式。然而，以光屏障式为例，如图1所示，裸眼3D显示装置包括显示面板10和光栅20，显示面板10包括左眼像素110和右眼像素120，左眼像素110通过光栅20只能被左眼看到，右眼像素120通过光栅只能被右眼看到。由于左眼像素110和右眼像素120是显示面板像素的1/2，因而3D显示时观看者看到的图像的分辨率会降低。柱面镜式、指向性背光式与光屏障式显示原理相同，都存在分辨率降低的情况，将会降低用户体验。
图2(a)示出了根据本公开实施例的显示装置。显示装置包括：显示单元30、调光结构40和控制器50。
具体地，显示单元30可周期性地分时显示n个不同视角的图像，其中一帧显示一个视角的图像，n≥2，n为正整数。调光结构40可变换为m种不同状态，且调光结构40可在不同状态下将显示单元30发出的光调节为射向不同观看位置的方向；m＞n，m为正整数。控制器50可与调光结构40耦接(连接)，用于控制调光结构40周期性地变换n种不同状态，以将n个不同视角的图像周期性地射向n个观看位置。
如图2(a)所示，调光结构40可被设置在显示单元30的出光侧，这样调光结构40便可以对显示单元30出射的光进行调节。
图2(b)示出了根据本公开实施例的显示装置。如图2(b)所示，显示单元30可被设置在调光结构40的周围，且显示单元30发出的光可以完 全射到调光结构40上。由此，调光结构40可以对照射到其上的光进行调节。除此以外，图2(b)中的显示装置与图2(a)中的显示装置的结构和功能相同，不再详细描述。
可理解地是，显示单元30和调光结构40的位置也可根据其它实施例而被布置。
在n个不同视角的图像射向n个观看位置的情况中，由于针对每个视角的图像与该视角的图像射向的观看位置是一一对应的，因此显示单元30显示的图像的变化与调光结构40状态的变化应该是同步的，一一对应的。例如，响应于显示单元30显示第一视角的图像，调光结构40的状态为可将显示单元30发出的光的方向调节为与第一视角对应的观看位置的方向，以向该观看位置提供对应于的第一视角的图像。响应于显示单元30显示第二视角的图像，调光结构40的状态同步发生变化，调光结构40可以将显示单元30发出的光的方向调节为与第二视角对应的观看位置的方向。依次类推，此处不再赘述。
在本公开的实施例中，对于调光结构40的类型不进行限定，只要调光结构40的状态可以发生变化，且调光结构40可在不同状态下将显示单元30发出的光调节为射向不同方向即可。调光结构40例如可以是液晶组件，也可以是多个微镜片等。
图3(a)和图3(b)分别示出了根据本公开实施例的调光结构将某一视角的图像射向一个观看位置的方向的结构示意图。如图3(a)所示，观看位置为一个点，经调光结构40调节后，显示单元30发出的光均射向该点。如图3(b)所示，观看位置为人眼位置所在的竖直线的位置，经调光结构40调节后，显示单元30发出的光均射向人眼位置所在的竖直线的位置处，此时调光单元40只对显示单元30发光的光进行水平方向的调节，竖直方向不进行调节。
图4(a)、图4(b)和图4(c)分别示出了根据本公开实施例的调光结构的结构示意图。如图4(a)所示，调光结构40可以包括沿水平方向依次排列的多个条状调光单元401。
如图4(b)所示，调光结构40也可包括多个点阵排列的调光单元401。
由于调光结构40可变换为m种不同状态，因而调光单元401也应可以变换成多种状态。此外，每个调光单元401都可以独立地控制射到其上的光的出射方向。
可理解的是，调光单元401的数量越多，调光结构40可以更精确地将每个视角的图像射向该视角对应的观看位置。进一步地，调光单元401的数量可以与显示单元30显示的图像的分辨率相同。示例的，在显示单元30显示的图像的分辨率为1920*1080的情况下，调光结构30可以有1920*1080个调光单元401，且每个调光单元401可以对一个像素发出的光进行调节时。由此，调光结构40可以精确地将每个视角的图像射向该视角对应的观看位置。
在本公开实施例中，由于调光结构40包括点阵排列的多个调光单元401，因而多个调光单元401可以将显示单元30发出的光调节为多个方向，相对于调光单元401为条状，点阵排列的多个调光单元401可以更精确地调节显示单元30发出的光的方向，且能够调节的方向更多。在此基础上，点阵排列的多个调光单元401还可以将显示单元30发出的光调节为射向一个点。
如图4(c)所示，调光单元401可以是微镜片。微镜片可在控制器50的控制下发生转动。微镜片可以对照射到其上的光的出射方向进行调节。
图5示出了根据本公开实施例的微镜片状态发生变化的示意图。图5中仅示意性地示出一个微镜片。如图5所示，当微镜片的角度发生变化时，光的出射方向也相应发生变化。附图5中仅示意出了一个微镜片的四种状态。
在本公开的实施例中，对于控制器50如何控制微镜片转动不进行限定，只要微镜片在控制器50的控制下能发生转动即可。本公开实施例中的控制器50控制微镜片的转动原理可以和DLP(Digital Light Processing，数字光处理)中DMD(Digital Micromirror Device，数字微镜晶片)上的多个微镜片的转动原理相同。此外，当调光单元401为微镜片时，为了确保调光 结构40可以精确地对显示单元30发出的光进行调节，调光结构40可由数十万甚至数百万的微镜片组成，且微镜片的变换速率可至少达1000次/秒。
在本公开的实施例中，当调光单元401是微镜片时，由于微镜片在控制器50的控制下会发生转动，因而微镜片的状态可以发生改变，从而射到微镜片上的光的出射方向会发生变化。在此基础上，本公开实施例提供的调光单元401结构简单，易于调节。
图6示出了根据本公开实施例的显示装置的结构示意图。图6中的显示装置与图2(a)中的显示装置的结构基本相同。显示装置包括：显示单元30、调光结构40和控制器50。其中，控制器50可包括：转动单元501、信号发送单元502和处理单元503。具体地，转动单元501与微镜片耦接(固定连接)，从而带动微镜片转动。信号发送单元502可发送具有不同宽度的脉冲信号。处理单元503可与信号发送单元502和转动单元501耦接(连接)，用于将具有不同宽度的脉冲信号转化为控制信号，可根据控制信号来控制转动单元501的转动方向和转动角度。
在本公开的实施例中，对于转动单元501的结构不进行限定，例如可以是铰链装置。
此外，对于处理单元503如何将脉冲信号转化为能够控制转动单元501转动方向和转动角度的控制信号不进行限定。示例的，处理单元503可以包括信号接收单元、存储单元和地址电极，信号接收单元在接收到脉冲信号后，可以根据脉冲信号对存储单元进行寻址，并通过静电激活地址电极，地址电极便会促使转动单元501转动。脉冲信号的不同会影响转动单元501的转动方向和转动角度，进而会影响微镜片的倾斜方向和倾斜角度，还会影响微镜片的倾斜时间。
进一步地，转动单元501可被设置在每个微镜片上。信号发送单元502和处理单元503可被设置在每个微镜片上，也可以将多个信号发送单元502和处理单元503集成在一起。
在本公开的实施例中，通过信号发送单元502发送具有不同宽度的脉冲信号。处理单元503对脉冲信号进行处理，以提供控制信号，从而可以 控制转动单元501的转动方向和转动角度，进而可以控制微镜片的倾斜方向、倾斜角度和倾斜时间。
另一方面，对于显示单元30的类型不进行限定。示例的，显示单元30可以是显示面板，也可以是包含图像信息的图像源和投影设备，投影设备可以对图像源提供的图像信息进行投影显示。
图7示出了根据本公开实施例的显示装置的结构示意图。图7中的显示装置与图2(a)中的显示装置的结构基本相同。显示装置包括：显示单元30、调光结构40和控制器50。其中，显示单元30包括投影设备301和图像源302。投影设备301例如可以是投影仪。具体地，图像源302可以为投影设备301提供图像信息。投影设备301与图像源302耦接(连接)，其可将图像源302提供的图像信息投影到调光结构40上。
在本公开的实施例中，图像源302为投影设备301提供的图像信息可以是包含不同视角的图像信息。
此外，在投影设备301将图像源302提供的图像信息投影到调光结构40后，调光结构40可以对射到其上的光线进行调节，以将不同视角的图像信息输入至不同的观看位置。
另一方面，对于一个观看者来说，观看位置可以是两个，分别是左眼观看位置和右眼观看位置。
在本公开的实施例中，n个不同视角的图像可包括n/2组图像(n是2的整数倍)，每组图像包括相邻帧显示的两个不同视角的图像(一个视角为左眼观看位置，另一个视角为右眼观看位置)。当每组图像中相邻帧显示的两个不同视角的图像包括3D显示的左眼图像和右眼图像时，则在每组图像中的左眼图像和右眼图像分别射向同一个观看者的左眼观看位置和右眼观看位置，此时该观看者便可以看到3D显示。当每组图像中的相邻帧显示的两个不同视角的图像相同时，若每组图像中两个相同的图像射向同一观看者的左眼观看位置和右眼观看位置时，此时该观看者便可以看到2D显示。基于上述，本公开实施例提供的显示装置既可以实现2D显示，还可以实现3D显示。
在此基础上，n/2组图像经显示单元30显示并经调光结构40调节后，可以全部实现3D显示，也可以全部实现2D显示，当然也可以部分实现3D显示，部分实现2D显示。在此基础上，当n/2组图像包含多组用于实现3D的图像时，多组用于实现3D的图像可以相同，也可以不同。若多组用于实现3D的图像相同时，则在将这多组图像显示并射向多个观看者时，多个观看者看到的3D图像相同。若多组用于实现3D的图像不相同时，则在将这多组图像显示并射向多个观看者时，多个观看者看的3D图像不同。类似地，当n/2组图像包含多组用于实现2D的图像时，与上述3D的情况相同，此处不再赘述。示例的，若n/2组图像包含2组用于实现2D的图像，一组图像关于一部动画片，另一组图像关于一部武打片，若将这2组图像经显示单元30显示后射向两个观看者(4个视角)，则两个观看者可以同时观看武打片和动画片。
在本公开实施例中，显示装置中的显示单元30可以分时显示n个不同视角的图像，且n个不同视角的图像在调光结构40的调节下会射向n个观看位置。因此，在n个不同视角的图像中包括3D显示的左眼图像和右眼图像的情况下，若左眼图像和右眼图像分别射向同一观看者的左眼和右眼时，显示装置可以实现3D显示。与一帧同时显示两个视角的图像且两个视角的图像分别射向左眼位置和右眼位置的3D显示技术相比，由于本公开实施例的显示单元30一帧显示一个视角的图像，且一个视角的图像射向一个观看位置，多个视角的图像分时显示，因此在进行3D显示时并不会降低显示装置的分辨率。
在本公开实施例中，显示装置还可包括人眼位置识别器。人眼位置识别器可获取人眼的位置。其中，对于人眼位置识别器如何获取人眼位置不进行限定。示例的，人眼位置识别器可以包括摄像头和图像处理器，摄像头可以采集人眼，图像处理器可以根据摄像头采集到的人眼计算出人眼位置。此外，当摄像头采集到多只眼睛时，图像处理器可以根据左眼和右眼的经验值，确定出多只眼睛中哪两只眼睛是同一个观看者的左眼和右眼。
具体地，调光结构40可以根据所识别出的人眼位置，将显示单元30 发出的光调节为射向人眼位置，这样观看者便可以在多个位置观看到显示单元30显示的图像。通常，对于裸眼3D显示装置，只有在特定的观看位置才能看到3D显示效果，因而观看者在观看前需要移动位置寻找最佳3D观看位置。然而，在本公开的实施例中，当显示单元30显示的n个不同视角的图像包括3D显示的左眼图像和右眼图像时，人眼位置识别器识别到人眼位置后，调光结构40便可以对左眼图像进行调节使其射向观看者的左眼，对右眼图像进行调节使其射向观看者的右眼，因此观看者无需移动仍可以在多个位置观看到3D显示。
在本公开实施例中，n个不同视角的图像包括n/2组相邻帧显示的左眼图像和右眼图像，每组图像中的左眼图像和右眼图像分别射向同一个观看者的左眼观看位置和右眼观看位置(n是2的整数倍)。其中，左眼图像和右眼图像是构成3D显示的左眼图像和右眼图像。当每组图像中的左眼图像和右眼图像分别射向同一观看者的左眼观看位置和右眼观看位置时，此时该观看者便可以看到3D显示。
此外，由于每组图像都可以实现3D显示，当n/2大于1时，因而多组图像可以在多个位置实现3D显示，从而可以实现多人观看3D显示，且分辨率不随视角的增多而降低。其中，n/2组图像可以相同，也可以不同。
本文中描述的单元可以实现为处理器和存储器的组合，其中处理器执行存储器中存储的程序以实现相应单元的功能。本文中描述的单元也可以完全的硬件实施方式实现，包括专用集成电路(ASIC)、现场可编程门阵列(FPGA)等。
图8示出了根据本公开实施例的显示装置的控制方法的示意性流程图。如图8所示，在方法中，在步骤S100，控制显示单元30周期性地分时显示n个不同视角的图像，其中一帧显示一个视角的图像。在步骤S101，将n个不同视角的图像周期性地射向n个观看位置，其中n≥2，n为正整数。
在本公开的实施例中，对于一个观看者来说，观看位置可以是两个，分别是左眼观看位置和右眼观看位置。
在本公开的实施例中，n个不同视角的图像可包括n/2组图像(n是2 的整数倍)，每组图像包括相邻帧显示的两个不同视角的图像(一个视角为左眼观看位置，另一个视角为右眼观看位置)。当每组图像中相邻帧显示的两个不同视角的图像包括3D显示的左眼图像和右眼图像时，则在每组图像中的左眼图像和右眼图像分别射向同一个观看者的左眼观看位置和右眼观看位置，此时该观看者便可以看到3D显示。当每组图像中的相邻帧显示的两个不同视角的图像相同时，若每组图像中两个相同的图像射向同一观看者的左眼观看位置和右眼观看位置时，此时该观看者便可以看到2D显示。基于上述，本公开实施例提供的用于控制显示装置的方法既可以控制实现2D显示，还可以控制实现3D显示。
在本公开的实施例中，由于显示装置中的显示单元30可以分时显示n个不同视角的图像，且n个不同视角的图像可以射向n个观看位置，因而当n个不同视角的图像中包括3D显示的左眼图像和右眼图像时，若左眼图像和右眼图像射向同一观看者的左眼和右眼时，则显示装置便可以实现3D显示。与一帧同时显示两个视角的图像且两个视角的图像分别射向左眼位置和右眼位置的3D显示技术相比，由于本公开实施例的显示单元30一帧显示一个视角的图像，且一个视角的图像射向一个观看位置，多个视角的图像是分时显示的，因此在进行3D显示时不降低显示装置的分辨率。
在本公开实施例中，n个不同视角的图像可包括n/2组相邻帧显示的左眼图像和右眼图像。方法还可包括：获取观看者的左眼观看位置和右眼观看位置，将每组图像中的左眼图像和右眼图像分别射向同一观看者的左眼观看位置和右眼观看位置。
此处，左眼图像和右眼图像是构成3D显示的左眼图像和右眼图像。当每组图像中的左眼图像和右眼图像分别射向同一观看者的左眼观看位置和右眼观看位置时，该观看者便可以看到3D显示。此外，当获取到多只眼睛的位置时，可以根据左眼和右眼的经验值，确定出多只眼睛中哪两只眼睛是同一个观看者的左眼和右眼。
在此基础上，由于每组图像都可以实现3D显示，当n/2等于1时，显示单元30显示的一组图像只能在一个位置实现3D显示。当n/2大于1时， 显示单元30显示的多组图像可以在多个位置实现3D显示，从而可以实现多人观看3D显示，且分辨率不随视角的增多而降低。此外，n/2组图像可以相同，也可以不同。当n/2组图像相同时，多个位置显示的3D图像相同。当n/2组图像不完全相同时，多个位置显示的3D图像不完全相同。
在本公开实施例中，通过控制显示单元30显示的n个不同视角的图像包括n/2组相邻帧显示的左眼图像和右眼图像，并控制每组图像中的左眼图像和右眼图像分别射向同一观看者的左眼观看位置和右眼观看位置，这样显示装置便可以实现3D显示，由于一个视角的图像射向一个观看位置，因而本公开实施例在实现3D显示时，不会降低分辨率。当n/2大于1，该显示装置还可以在多个位置实现3D显示。
在此基础上，由于显示单元30显示的不同视角的图像可以精确地射向同一观看者的左眼观看位置和右眼观看位置，这样观看者便可以在多个位置观看到显示单元30显示的图像。相对于现有的裸眼3D显示装置，只有在特定的观看位置才能看到3D显示效果，因而现有技术中观看者在观看前需要移动位置寻找最佳3D观看位置，而本公开实施例，当显示单元30显示的n个不同视角的图像包括3D显示的左眼图像和右眼图像时，观看者无需移动，在获取到观看者的左眼观看位置和右眼观看位置后，便可以对左眼图像进行调节使其射向观看者左眼观看位置，对右眼图像进行调节使其射向观看者右眼观看位置，从而使得观看者可以在多个位置观看到3D显示。
在本公开实施例中，n个不同视角的图像可包括n/2组相邻帧显示的两个相同的图像。方法还包括：获取观看者的左眼观看位置和右眼观看位置。将每组图像中两个相同的图像分别射向同一观看者的左眼观看位置和右眼观看位置。
由于每组图像中相邻帧显示的两个图像相同，因而当将两个相同的图像分别射向同一观看者的左眼观看位置和右眼观看位置时，此时该观看者便可以看到2D显示。此外，当获取到多只眼睛的位置时，可以根据左眼和右眼的经验值，确定出多只眼睛中哪两只眼睛是同一个观看者的左眼和 右眼。
基于上述，当n/2大于1，显示单元30显示的多组图像可以在多个位置实现2D显示，从而可以实现多人观看2D显示。此时，n/2组图像可以相同，也可以不同。当n/2组图像相同时，多个位置显示的2D图像相同；当n/2组图像不完全相同时，多个位置显示的2D图像不完全相同，可以使不同的观看者观看不同的内容。
可理解的是，当对显示单元30显示的n个不同视角的图像不进行调节时，本公开实施例提供的显示装置也可以实现2D显示，与现有技术中的2D显示装置相同。
本公开实施例，通过控制显示单元30显示的n个不同视角的图像包括n/2组相邻帧显示的两个相同的图像，每组图像中两个相同的图像分别射向同一观看者的左眼观看位置和右眼观看位置，这样显示装置便可以实现2D显示。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
