附图说明
为了更清楚地说明本公开实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

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，所描述的实施例仅是本公开一部分的实施例，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无需创造性劳动的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。
本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
在进行光场显示的过程中，需要显示处于不同景深的图像信息，每个景深的图像信息相当于一幅二维图像。因此，光场显示所需的数据量远远大于传统的平面显示(仅显示一幅二维图像的信息)所需的数据量。
具体的，上述数据量也可以称为信息量，即光场显示所显示的内容。例如，在二维平面显示过程中，显示的图像信息仅包括在二维平面上的像点的颜色和亮度信息等。而在光场显示中，所显示的立体图像中还包括了景深信息，这可以简单理解为每个景深位置的显示内容即为一个二维平面图像。为了实现较好的光场显示效果，需要大量的处于不同景深的图像信息，同时还需要实现动态显示视差信息。利用所述视差信息，观看者在从不同角度观看时，可以看到处于不同景深的显示内容，体现出立体显示的深度信息。
由此可知，所述光场显示相对于二维平面显示来说，在景深维度和视差方向维度都增加了大量需要显示的图像内容。因此，在光场显示过程中，用于显示的像素数目越多，光场显示的图像越细腻，能覆盖的景深范围越大，再现出的图像细节越丰富，观看的角度越宽。
然而，在相关的平面显示器中，像素数目受到控制电路工艺的限制，难 以实现数量级的提升。在此种情况下，对进行光场显示的显示器的像素结构进行优化，从而提高显示的数据量和光场显示系统的视区范围，成为光场显示实用化的关键。
本公开提出了一种光场显示方法，对于不同视区中显示内容相同的发光点采用同一驱动电路进行驱动，使得在不增加驱动电路数目的基础上提高光场显示的视区数目，增大光场显示的可视范围，从而实现光场显示的实用化。其中，所述发光点可以对应于一个像素，也可以对应于一个像素的一部分。
根据本公开实施例，在所述光场显示方法中，所述光场显示包括N个视区，显示屏幕包括N个显示区域，所述N个显示区域与所述N个视区一一对应，每个显示区域包括M个发光点，所述N个显示区域中对应位置的发光点为一个发光点组，所述方法包括：利用同一驱动电路来驱动所述N个显示区域中属于同一发光点组的发光点，其中，所述N个视区彼此不重叠，N和M均为大于1的正整数。
图1示出了根据本公开实施例的显示屏幕的示意图，图2A示出了根据本公开实施例的一个显示屏幕与视区对应关系的示意图。以下将结合图1和图2A详细描述根据本公开实施例的光场显示方法。
如图1所示，所述显示屏幕例如可以是平面显示器，其上配置有发光点。在图1中示出的显示屏幕上，所述发光点对应于一个像素。在根据本公开的其它实施例中，所述发光点也可以对应于一个像素的一部分，将在下文详细介绍。
根据本公开实施例，可以将如图1所示出的显示屏幕上布置的像素划分为n*n＝N个显示区域，每个显示区域可以包括m*m＝M个像素(如虚线框所示出的)。其中，所述N个显示区域中的每个显示区域的像素的排列方式相同。
如图1所示，对于所述N个显示区域中的每一个显示区域，处于相同位置处的像素的显示内容相同。例如，每个显示区域中的第一个像素A 11的显示内容均相同。因此，显示屏幕上的每个显示区域的显示内容相同。
在根据本公开的实施例中，所述N个显示区域中对应位置的发光点为一个发光点组。例如可以将图1中的显示屏幕分为M个发光点组，其中，发光点组G 11包括图1中示出的每个显示区域中的像素A 11，发光点组G 1m可以包 括每个显示区域中的像素A 1m。每个发光点组包括的像素的显示内容相同，因此，可以采用同一驱动电路来驱动所述显示屏幕中属于同一发光点组的像素。例如，可以利用一个驱动电路来驱动包括像素A 11的发光点组G 11，利用另一个驱动电路来驱动包括像素A 1m的发光点组G 1m。
如图2A所示，所述显示屏幕经过透镜在像空间可以形成N个视区，所述N个视区彼此不重叠，所述N个显示区域与所述N个视区一一对应。由于图1中每个显示区域中处于相同位置的像素的显示内容相同，使得各个显示区域经过透镜形成的对应位置处的每个视区的显示内容相同。例如，显示区域N对应于视区N，显示区域N-1对应于视区N-1，以此类推，并且，每个视区的显示内容相同。
如图2A所示，所述N个显示区域通过同一个透镜形成所述N个视区，根据本公开的另一实施例，还可以通过多个透镜形成所述N个视区。所述显示区域中的像素经过透镜成像时的出光方向由像素与透镜位置关系以及透镜的焦距决定，因此可以根据实际参数来设计透镜和像素的位置关系。
在根据本公开实施例提供的光场显示方法中，如图1所示，显示屏幕由N个显示区域(n*n)组成，每个显示区域由M个像素(m*m)组成，每个显示区域内处于相同位置处的像素的显示内容相同。将显示区域中这些处于相同位置且显示内容相同的像素称为一组发光点组，通过同一驱动电路来驱动同一发光点组，即一套驱动电路同时控制各个显示区域中处于同一位置的像素，从而可以实现利用M个驱动电路来实现对于M*N个像素的驱动。在利用上述显示屏幕来进行光场显示时，每个显示区域通过透镜在像空间的不同位置处形成各自的视区(如图2A所示)，所有的视区组成完整的可视空间。
在不进行显示区域划分的光场显示中，M个驱动电路仅能驱动M个像素，所述M个像素在像空间形成的数据量相当于如图2A示出的一个视区的数据量。而根据本公开实施例的光场显示方法，可以实现利用M个驱动电路来驱动M*N个像素，所述M*N个像素经过透镜可以形成N个视区。由此可知，根据本公开的光场显示方法可以在不增加驱动电路的数目的条件下，将光场显示系统的可视范围由原来的1个视区增加到N个视区，实现大可视范围的光场显示，光场显示的数据量也增加了N倍。
根据本公开的实施例，还可以包括k个如图2A所示的显示屏幕，k为大于等于1的正整数。图2B示出了根据本公开实施例的多个显示屏幕与视区对应关系的示意图，其中，k等于4。所述k个显示屏幕中的每一个显示屏幕包括N个显示区域，所述k个显示屏幕中的每一个显示屏幕的N个显示区域的对应的视区彼此重叠。
例如，如图2B中所示出的，显示屏幕1、2、3和4中各自的显示区域1在像空间形成各自的视区N，所述各自的视区N彼此重叠；显示屏幕1、2、3和4中各自的显示区域N在像空间形成各自的视区1，所述各自的视区1也彼此重叠。
根据本公开实施例，如图2A所示出的，与所述显示屏幕相对应的透镜可以是单透镜、微透镜、液晶透镜等的形式，可以根据显示屏幕的尺寸、像素尺寸等参数来设计透镜的参数，这并不构成对于本公开的限制。在如图2B中所示出的多个显示屏幕的情形中，还可以采用透镜阵列、微透镜阵列的形式来实现，这也不构成对于本公开的限制。
通过图2B中示出的多个显示屏幕经过透镜形成彼此重叠的视区，可以增加像空间显示内容的数据量，即增加光场显示的景深和视差信息，提高光场显示的显示效果，解决现有技术中像素数目有限导致的光场显示数据量不足的问题。
根据本公开的光场显示方法还可以包括：对于所述N个显示区域中的至少一个显示区域，通过开关将该显示区域与驱动电路连接，所述开关用于导通或切断所述驱动电路对所述显示区域的驱动。其中，通过开关将该显示区域与驱动电路连接包括：通过M个开关分别将该显示区域中的M个发光点与其对应的驱动电路连接。
根据本公开实施例，利用上述与驱动电路连接的开关可以控制与其连接的发光点是否发光，从而控制是否在像空间中形成对应的视区，实现光场显示过程中的防窥功能。例如，通过切断连接显示区域1与驱动电路的开关，来实现对于视区N的防窥功能，即处于视区N位置处的观看者不能看到显示内容。
在根据本公开的上述光场显示的方法中，将显示屏幕划分为N个显示区域，每个显示区域中处于相同位置的像素由同一驱动电路进行控制，即一个 驱动电路同时控制各个显示区域中处于同一位置的像素，所述显示区域与视区一一对应。因此，可以将每个显示区域中的M个像素与M个开关连接。例如，可以通过M个开关1来控制显示区域1中的M个像素是否发光，所述与显示区域1连接的M个开关的闭合和断开保持一致。在由M个所述开关1控制显示区域1的像素不发光的情况下，则在像空间不形成对应的视区N，从而实现针对于视区N的防窥效果，即观看者从视区N的位置无法观看到显示内容。
根据本公开的另一实施例，所述开关还可以控制与其连接的发光点的显示内容(诸如亮度、颜色等)，从而实现所述防窥功能。例如，通过开关控制显示区域中发光点的显示内容，从而使得与该显示区域对应的视区与其他视区相比，显示不同的内容，即通过显示内容的改变来实现防窥效果。
图3示出了根据本公开实施例的显示屏幕与开关连接关系的示意图，图4示出了图3中示出的显示屏幕与视区对应关系的示意图。以下将结合图3和图4来详细描述根据本公开实施例的利用开关实现防窥功能的过程。
如图3所示，为便于描述，将图1中示出的每个显示区域由一列像素表示。例如，显示区域1包括一组列像素B 11-B m1，显示区域2包括一组列像素B 12-B m2，以此类推。每个显示区域在像空间形成对应的视区。根据本公开实施例，每个显示区域内的像素可以与各自的信号线连接，通过所述信号线来传输像素的驱动信号。由此，可以将各个显示区域内的像素与对应的开关连接，例如，将显示区域1中的像素与开关1连接起来。在开关1闭合时，导通驱动电路对于显示区域1内的像素的驱动，即，驱动信号可以经由信号线传输到显示区域1内的各个像素，使得所述像素发光，从而形成视区N；在开关1断开时，切断驱动电路对于显示区域1内的像素的驱动，即断开信号线与像素之间的传输，所述像素不发光，即不形成视区N。
如图4所示出的，当与列1(对应于显示区域1)包括的像素连接的开关导通时，列1像素在驱动电路的驱动下发光，并通过透镜在像空间形成视区3，处于视区3位置的观看者可以看到对应的显示内容。而当与列1包括的像素连接的开关断开时，即切断了列1像素与驱动电路的连接，列1像素不发光，在像空间视区3的位置处不呈现显示内容。因此，在此种情况下，处于视区3位置处的观看者不能观看到显示内容，而处于视区1和视区2的观看 者可以观看到显示内容，从而实现对于视区3的防窥效果。
根据本公开的实施例，可以通过所述开关来实现驱动电路与像素之间的切断或导通的功能，从而实现光场显示防窥功能。根据本公开的其他实施例，还可以通过控制驱动信号的方式来实现所述开关的功能。例如，当需要对图6中示出的视区3的位置进行防窥时，即使得与视区3对应的显示区域1不显示，则可以控制对应的驱动信号来使得显示区域1内的像素不发光，从而实现对于视区3的防窥效果。
根据本公开的另一实施例，所述显示屏幕中的发光点还对应于一个像素的一部分。其中，所述显示屏幕包括M个像素，通过对一个像素进行区域划分来形成属于同一发光点组的N个发光点。
例如，如图5所示出的，可以通过像素开口技术来实现像素区域的划分。所述开口可以基于现有的显示屏制造工艺来实现。传统的像素只存在一个发光口，因此可以形成一个发光点。例如，可以通过在传统的发光口上增加遮光掩模的方式来在每个像素上形成N个发光点。
图6中示出了经过像素开口形成多个发光点的像素的示意图。常规的像素仅包括一个发光口，因此在发光时仅形成一个发光点。根据如图5所示出的像素开口技术处理之后，可以在常规的像素上形成多个开口，当该像素发光时，则可以经过开口形成多个发光点。因此，如图6中所示出的，经过像素开口将左侧的像素的发光点的数目由一个增加至30个。
根据本公开实施例，可以将上述在一个像素上形成的不同位置处的发光点称为一组发光点组。当利用驱动电路来驱动该像素发光时，每个发光点显示的内容相同。
根据本公开实施例，显示屏幕上的M个像素可以分别对应于M个透镜，通过所述M个透镜使得所述M个发光点组中对应位置的发光点形成一个视区，从而使得所述M个发光点组形成N个视区。
图7示出了根据本公开实施例的发光点与透镜的对应关系的示意图。如图7所示出的，在一个像素内，不同位置处的发光点相对于透镜的位置不同，经过透镜后形成不同方向的光线。其中，每个像素中的N个发光点的显示内容相同，经过透镜后，可以在像空间中的N个视区中形成相同的显示内容。显示屏幕中的M个像素经过M个透镜在像空间形成完整的N个视区的显示 内容。
根据上述实施例，对于显示屏幕上的M个像素的每一个，将其发光区通过掩模的方式划分为N个像素开口，所述N个像素开口可以形成N个发光点。M个像素的中处于对应位置处的发光点将在像空间形成一个视区，每个像素中不同位置处的发光点对应于像空间中的不同的视区。所述M个像素可以通过M个驱动电路来控制，因此，根据本公开实施例，可以实现利用M个驱动电路驱动M个像素，并在像空间形成N个视区。所述N个视区组合在一起，显著提高光场显示的可视范围。
根据本公开提出的上述光场显示方法，在不改变驱动电路的条件下，将像素的发光区划分为若干小开口(N个)，从而能成倍(N倍)提高显示屏幕的发光点的数目(如图6所示)。每个像素对应于一个透镜，该像素中的不同开口形成的发光点经过透镜在像空间形成不同视区内的显示内容。所述M个像素的不同发光点的光线将在像空间形成等同于发光点数目(N个)的显示相同内容的视区。人眼在不同的视区均能观看到相同的显示内容，从而将光场显示系统的可视范围由原本的一个视区提高到N个视区，实现了大可视范围的光场显示。
根据本公开实施例，在进行光场显示过程中，所述包括像素开口的显示屏幕还可以为k个显示屏幕，k为大于等于1的正整数。所述k个显示屏幕中的每一个显示屏幕中的显示区域经过透镜，在像空间形成各自的视区。
所述k个显示屏幕中的每一个显示屏幕包括N个显示区域，所述k个显示屏幕中的每一个显示屏幕的N个显示区域的对应的视区彼此重叠。
例如，显示屏幕1-k中的各自的显示区域1在像空间形成各自的视区N，所述各自的视区N彼此重叠；显示屏幕1-k中的各自的显示区域N在像空间形成各自的视区1，所述各自的视区1也彼此重叠。
通过上述k个显示屏幕经过透镜形成彼此重叠的视区，可以增加像空间显示内容的数据量，即增加光场显示的景深和视差信息，提高光场显示的显示效果，解决现有技术中像素数目有限导致的光场显示数据量不足的问题。

根据本公开的一个实施例，所述每个发光点为一个像素，每个显示区域包括M个像素，所述N个显示区域具有M个发光点组；所述N个显示区域通过同一个透镜形成所述N个视区，或者通过多个透镜形成所述N个视区；所述N个显示区域的像素的排列方式相同。例如上文中所描述的，图1示出了所述显示屏幕的示意图，图2A和图2B示出了显示屏幕经过透镜形成视区的示意图。利用上述光场显示装置，可以实现通过M个驱动电路来驱动M*N个像素。具体的，利用所述光场显示装置进行光场显示的方法在此不再赘述。
所述光场显示装置还包括开关，所述开关连接所述N个显示区域中的至少一个显示区域和该显示区域的驱动电路，用于导通或切断所述驱动电路对所述显示区域的驱动。其中，可以通过M个开关分别将该显示区域中的M个发光点与其对应的驱动电路连接。例如，通过切断连接显示区域1与驱动电路的开关，来实现对于视区N的防窥功能，即处于视区N位置处的观看者不能看到显示内容。
根据本公开的另一实施例，其中，所述显示屏幕可以包括M个像素，通过对一个像素进行区域划分来形成属于同一发光点组的N个发光点；所述M个像素分别对应于M个透镜，通过所述M个透镜用于使得所述M个发光点组中对应位置的发光点形成一个视区，从而使得所述M个发光点组形成N个视区；所述N个所述发光点利用掩模形成。
