具体实施方式
针对多视点裸眼3D显示容易出现视区串扰现象的问题，本公开实施例提供了一种显示装置及其显示方法。
下面结合附图，对本公开实施例提供的显示装置及其显示方法的具体实施方式进行详细地说明。附图中各部件的大小和形状不反映真实比例，目的只是示意说明本公开内容。
图1为本公开实施例提供的显示装置的结构示意图，如图1所示，本公开实施例提供的显示装置，可以包括：显示面板10，及分光器件20。
图2为本公开实施例中显示面板的平面结构示意图，结合图1和图2，显示面板10可以包括：衬底基板101，以及位于衬底基板101之上的多个像素岛102；像素岛102包括：沿第一方向x和第二方向y排列的多个子像素p；在像素岛102中，在第一方向x上排列的一排子像素p的颜色相同，在第二方向y上排列的一排子像素p的颜色互不相同；第一方向x与第二方向y相 互交叉。在具体实施时，显示面板10中的各像素岛102的结构可以一致，各像素岛102沿第一方向x和第二方向y可以呈阵列排布。图3为本公开实施例中显示面板的另一平面结构示意图，显示面板中的各像素岛可以按照图2所示的方式进行排列，各行像素岛在第一方向x上对齐设置，各列像素岛在第二方向y对齐设置，其中，在第一方向x上排列的一排像素岛102可以为一行像素岛，在第二方向y上排列的一排像素岛102可以为一列像素岛；或者，显示面板中的各像素岛可以按照图3所示的方式进行排列，即各行像素岛在第一方向x上对齐设置，各列像素岛在第二方向y错开一定距离，例如错开的距离可以为像素岛102在第二方向y上的宽度的一半，此处只是距离说明，不对错开的距离进行限定。
分光器件20，位于显示面板10的显示面一侧，被配置为将显示面板10出射的一部分光线偏折至第一区域，将另一部分光线偏折至第二区域，例如，第一区域可以为左眼WL所在的区域，第二区域可以为右眼WR所在的区域；
显示面板10的中心显示区域内的像素岛102对应的主瓣角与瞳距角满足以下关系式：
Figure PCTCN2020132891-appb-000008
其中，α表示主瓣角，β表示瞳距角；主瓣角为像素岛出射的光线在观看位置处且在第一方向上的投影角度；瞳距角为在观看位置处双眼相对于显示面板的张角。其中，显示面板的中心显示区域可以理解为：显示面板的显示区域的几何中心附近的区域，且显示区域的几何中心位于中心显示区域内部。
图4为本公开实施例中主瓣角与瞳距角的对应关系示意图，如图4所示，图中，位置A位于显示面板10的中心显示区域内，方框1、2、3….n表示一个像素岛出射的光线在观看位置处的投影区域，主瓣角为投影区域1、2、3….n两端分别与位置A的连线构成的夹角。位置A处的像素岛出射的光线在观看位置Q1处且在第一方向x的投影角度为α1，即观看位置Q1处的主瓣角为 α1。位置A处的像素岛出射的光线在观看位置Q2处且在第一方向x的投影角度为α2，即观看位置Q2处的主瓣角为α2。瞳距角为观看位置处左眼WL与右眼WR分别与位置A的连线构成的夹角。观看位置Q1处的瞳距角为β1，观看位置Q2处的瞳距角为β2。
本公开实施例提供的显示装置中，将像素岛分割为多个子像素，各子像素所在的位置出射的光线经过分光器件后，一部分偏折至左眼所在的区域，另一部分偏折至右眼所在的区域，用户在观看显示装置时，左眼接收左眼视图，右眼接收右眼视图，经大脑融合作用形成立体图像，从而实现超多视点裸眼3D显示。当主瓣角等于三分之二倍的瞳距角时，用户在观看位置观看显示装置时，用户的双眼不会落在同一个像素岛对应的投影区域内，也就是说，用户的左眼和右眼不会重复观看同一个像素岛，将主瓣角设置为大于或等于三分之二倍的瞳距角，可以保证用户的左眼和右眼观看的视图能够区分开，防止多视点裸眼3D显示的影像出现视区串扰的现象。
在具体实施时，为了使三维显示效果较好，上述显示面板可以采用分辨率较高的显示面板，例如，上述显示面板可以为液晶显示面板、有机电致发光显示面板或微型发光二极管显示面板，当然，上述显示面板也可以为其他类型的显示面板，此处不做限定。在显示面板中，衬底基板一般位于显示面板的底部，具有支撑以及承载其它部件的作用。衬底基板的形状和尺寸可以与显示面板相适应，衬底基板的材料可以为玻璃，也可以为其他具有支撑作用的材料，在此不做限定。
可选地，上述分光器件可以为障壁光栅、柱状透镜或液晶光栅，当然，分光器件也可以采用其他类型的光栅，或者，分光器件也可以为其他能够起到分光作用的光学器件，此处不做限定。
图5为本公开实施例中像素岛的子像素排列结构的示意图，同时参照图5，一个像素岛102中可以包括三基色的子像素，例如，像素岛102可以包括红色子像素pr、绿色子像素pg和蓝色子像素pb。其中，红色子像素pr、绿色子像素pg和蓝色子像素pb的数量相同；红色子像素pr沿第一方向x排列成 一行，绿色子像素pg沿第一方向x排列成一行，蓝色子像素pb沿第一方向x排列成一行；红色子像素行、绿色子像素行和蓝色子像素行沿第二方向y排列，从而使像素岛102中的子像素呈阵列排布。可选地，第一方向x和第二方向y可以为相互垂直的两个方向，其中第一方向x可以为水平方向，第二方向y可以为竖直方向，在此不做限定。
进一步地，本公开实施例提供的上述显示装置，参照图4，显示面板的中心显示区域内的像素岛对应的主瓣角与瞳距角满足以下关系式：
Figure PCTCN2020132891-appb-000009
当主瓣角等于二分之三倍的瞳距角时，用户在观看位置观看显示装置时，用户的双眼落在同一个像素岛对应的投影区域内，并且，此时用户的双眼在该投影区域内存在一个可动空间，将主瓣角设置为小于或等于二分之三倍的瞳距角，可以保证用户的左眼和右眼观看的视图连续性较好。
综上，显示面板的中心显示区域内的像素岛对应的主瓣角与瞳距角满足以下关系式：
Figure PCTCN2020132891-appb-000010
这样，既能够保证左眼和右眼观看的视图不会发生串扰，又能够保证左眼和右眼观看的视图连续性较好，提高多视点裸眼3D显示的显示效果。
在具体实施时，本公开实施例提供的上述显示装置中，像素岛对应的视点数量满足以下关系式：
Figure PCTCN2020132891-appb-000011
Figure PCTCN2020132891-appb-000012
其中，n表示视点数量；γ表示视点间隔角；d表示相邻视点在观看位置处的间距。
本公开实施例中，像素岛对应的视点数量为：像素岛在观看位置对应的投影区域与视点间隔角的比值，即像素岛对应的主瓣角与视点间隔角的比值。通过将像素岛对应的视点数量设置在上述范围内，可以保证用户在观看位置 水平定点观看显示装置时，左眼和右眼接收的视图正确且串扰较低。
此外，显示面板的中心显示区域内的像素岛对应的主瓣角与瞳距角还满足关系式：α＝β+γ·k；其中，k为整数，且k＞2。
并且，像素岛中第一方向上一排子像素p的数量M满足：M≥n，像素岛尺寸的纵横比K满足：K＝3/M，以使三维图像与二维图像比例一致，解决三维图像的片源处理问题。
在具体实施时，本公开实施例提供的上述显示装置中，还可以包括：
眼球追踪器，被配置为检测眼球的位置，并发送检测到的眼球的位置信息；
图像调整器，接收眼球追踪器发送的眼球的位置信息，并根据接收到的眼球的位置信息，切换显示面板中子像素的图像数据。
本公开实施例中，可以将眼球追踪器固定于显示面板的显示面一侧，当用户观看显示面板时，眼球追踪器可以通过检测眼球的位置，实现对人眼位置的定位，以确定人眼的相对坐标位置，图像调整器接收到眼球追踪器发送的眼球的位置信息后，根据接收到的眼球的位置信息，切换显示面板中子像素的图像数据，以刷新对应的左眼视图和右眼视图。其中，眼球追踪器的定位精度范围需保证对应像素岛中子像素的投影宽度，为了实现三维图像的平滑过渡，眼球追踪器的定位精度范围需小于等于4mm。
此外，本公开实施例提供的上述显示装置中，如图1所示，还可以包括：位于显示面板10与分光器件20之间的透明光学膜层30；
透明光学膜层30的厚度满足以下关系式：
Figure PCTCN2020132891-appb-000013
其中，H表示透明光学膜层的厚度；Px表示子像素在第一方向上的宽度；L表示观看位置与分光器件之间的距离；T表示双眼瞳距，一般在4cm左右。
在实际应用中，透明光学膜层30可以采用光学玻璃或光学树脂材料制作，或者，也可以采用其他透明光学材料，此处不做限定。可以根据子像素在第 一方向上的宽度Px、双眼瞳距T及观看位置与分光器件之间的距离L，来调节透明光学膜层30的厚度，以使显示装置的三维效果更好。
本公开实施例提供的上述显示装置中，像素岛的尺寸满足以下关系式：
Figure PCTCN2020132891-appb-000014
其中，D表示像素岛在第一方向上的宽度。
在观看位置处，若像素岛在第一方向上的宽度与人眼的张角小于一分角(即1/60°)，则显示装置形成的三维影像能够满足视网膜的分辨率，使人眼的视网膜能够在接收左眼视图和右眼视图后形成三维图像。
基于同一发明构思，本公开实施例还提供了一种上述任一显示装置的显示方法，由于该显示方法解决问题的原理与上述显示装置相似，因此该显示方法的实施可以参见上述显示装置的实施，重复之处不再赘述。
图6为本公开实施例中像素岛的子像素排列结构的另一示意图，图7为本公开实施例中像素岛的子像素排列结构的另一示意图，如图6和图7所示，显示面板中的每一个像素岛102包括多个子像素组102＇，每一个子像素组102＇包括在第一方向x上相邻的至少两个子像素p。图6和图7中以像素岛102包括三行十六列子像素为例进行示意，在具体实施时，可以根据实际需求设置像素岛中子像素的数量和排布方式，此处不做限定。图6中以每一个子像素组102＇中包括四列子像素p为例进行示意，图7中以每一个子像素组102＇中包括两列子像素p为例进行示意，在实际应用时，可以根据实际需求对子像素组中子像素的数量进行设置，此处不做限定。在具体实施时，像素岛的各子像素组中的子像素数量可以设置为相同，即对像素岛进行平均分组得到多个子像素组，此外，像素岛的各子像素组中的子像素数量也可以设置为不相同，此处不做限定。
图8为本公开实施例提供的显示方法的流程示意图，如图8所示，本公开实施例中的显示方法，可以包括：
S201、检测用户双眼的位置信息；例如，可以在显示面板中设置眼球追 踪器，以追踪眼球的位置信息；
S202、根据检测到的用户双眼的位置信息，对显示面板中子像素的图像数据进行切换；其中，向像素组中的各子像素中加载相同的图像数据。
本公开实施例提供的显示方法中，通过检测用户双眼的位置信息，并根据检测到的用户双眼的位置信息，对显示面板中子像素的图像进行切换，以刷新左眼和右眼在对应观看位置的视图信息，可以准确的控制左眼视图与右眼视图的切换。并且，向子像素组中各子像素中加载相同的图像数据，降低了单一时刻二维显示面板的数据量，同时也降低了三维数据的数据量，解决了采用高分辨率的显示面板实现超多视点3D显示时驱动困难，及同一时刻2D数据传输量巨大的问题，有利于实现实时3D场景再现。
图9为本公开实施例中各子像素组中加载的图像数据与人眼观看的视图之间的对应关系示意图，并且，图9中以图6所示的像素岛结构为例进行示意图，即图9中每一个子像素组中包括四列子像素，结合图6和图9所示，在t1时刻至t4时刻用户的双眼分别在不同的位置。在t1时刻时，向第一子像素组102a中的各子像素同时输入第13视图的图像数据，向第二子像素组102b中的各子像素同时输入第1视图的图像数据，使投影区域位置处的左眼WL接收到第1视图的图像，右眼WR接收到第13视图的图像。在t2时刻时，向第一子像素组102a中的各子像素同时输入第14视图的图像数据，向第二子像素组102b中的各子像素同时输入第2视图的图像数据，使投影区域位置处的左眼WL接收到第2视图的图像，右眼WR接收到第14视图的图像。其他时刻，以此类推。这样，每一个时刻只需向像素岛输入4个灰阶的图像数据，相比于向像素岛中的各子像素分别输入16个灰阶，采用时分复用一个子像素复用四次，每一个时刻向像素岛输入的数据量降低为原来的25％。
此外，也可以采用图7所示的分组方式进行显示，即采用相邻两列子像素进行信号合同控制，这样，每一个时刻向像素岛输入的数据量降为原来的50％，并且，可以降低左眼视图与右眼视图之间的串扰。
基于同一发明构思，本公开实施例还提供了一种上述任一显示装置的显 示方法，由于该显示方法解决问题的原理与上述显示装置相似，因此该显示方法的实施可以参见上述显示装置的实施，重复之处不再赘述。
图10为本公开实施例提供的显示方法的流程示意图，如图10所示，本公开实施例提供的上述任一显示装置的显示方法，可以包括：
S301、检测用户双眼的位置信息；例如，可以在显示面板中设置眼球追踪器，以追踪眼球的位置信息；
S302、在检测到眼球的位置超出对应的可动区域时，切换显示面板中子像素的图像数据；
其中，可动区域满足以下关系式：
Figure PCTCN2020132891-appb-000015
其中，J表示眼球在观看位置处的可动区域；W表示显示面板的中心显示区域内的像素岛出射的光线在观看位置处的投影区域，即主瓣视区，一个主瓣视区W与一个主瓣角α对应。
本公开实施例提供的显示方法中，通过检测用户双眼的位置信息，当检测到眼球的位置超出对应的可动区域时，切换显示面板中子像素的图像数据。并且，在每一时刻，主瓣角的视区内视点分布于左右眼的可动区域内，这样，用户在观看显示面板时，每只眼睛在移动时都有一定的可动区域，在可动区域内左眼和右眼移动观看时可以获得相同的视差，眼球追踪器的定位精度只需要定位到可动区域的范围即可，无需定位到每一个视点。在具体实施时，眼球追踪器最低只需满足1/2的瞳距角即可，即眼球追踪器的精度只要大于1°即可，相比于相关技术中眼球追踪器的精度至少满足视点间隔角(一般取0.2°～0.4°即瞳孔大小)，降低了眼球追踪器的精度要求，降低了器件成本，并且，能够保证三维显示的视点连续性。
当主瓣角满足：
Figure PCTCN2020132891-appb-000016
时，例如，
Figure PCTCN2020132891-appb-000017
主瓣视区W内分布n个视点时，则左右眼可获得最大的可动区域为主瓣视区W的一半。图11为本公开实施例中显示装置的显示过程示意图，如图11所示，左眼可以在1～n/2视点之 间移动，右眼可以在n/2～n视点之间移动，左右眼不仅串扰最小且移动过程中可以获得相同的视差。眼球追踪器的定位精度只需要最小定位到可动区域即可，即定位精度为主瓣视区的一半。当眼睛在移动过程中超出可动区域，眼球追踪器将眼睛对应的位置信息反馈给图像调整器，图像调整器切换对子像素的图像数据，实现多视点图像的整体切换，从而消除3D图像反转区，实现超多空间3D图像连续观看。
继续参照图11，在t1时刻，向对应1～16视点的各子像素加载图像数据，在投影区域中显示1～16视点，其中，左眼对应1～8视点，右眼对应9～16视点，当左眼在1～8视点范围内移动，右眼在9～16视点范围内移动，可以实现左右眼连续视差观看。在t2时刻，当左眼移动到9视点位置处，眼球追踪器将眼球的位置信息发送至图像调整器，图像调整器根据眼球的位置信息，刷新对应9～24视点的各子像素的图像数据，其中，在投影区域中显示9～24视点，其中，左眼对应9～16视点，右眼对应17～24视点，从而实现水平超大空间连读密集超多视点。
当主瓣角满足：
Figure PCTCN2020132891-appb-000018
时，例如
Figure PCTCN2020132891-appb-000019
当主瓣视区W内分布n个视点时，则左右眼可获得最大的可动区域为主瓣视区的1/3，左眼可以在1～n/3视点之间移动，右眼可以在2n/3～n视点之间移动，左右眼不仅串扰最小且移动过程中可以获得相同的视差。眼球追踪器的定位精度只需要最小定位到可动区域即可，即定位精度为主瓣视区的1/3，当眼睛在移动过程中超出可动区域，眼球追踪器将眼睛对应的位置信息反馈给图像调整器，图像调整器切换对子像素的图像数据，实现多视点图像的整体切换，从而消除3D图像反转区，实现超多空间3D图像连续观看。
进一步地，本公开实施例提供的上述显示方法中，还可以包括：
向像素岛中的一部分子像素加载对应于左眼的图像数据，另一部分子像素加载对应于右眼的图像数据，其余的子像素不加载图像数据。
这样，可以降低二维显示面板的数据量，同时也降低了三维数据的数据 量，解决了采用高分辨率的显示面板实现超多视点3D显示时驱动困难，及同一时刻2D数据传输量巨大的问题，有利于实现实时3D场景再现。
图12为像素岛显示全视点图像的示意图，如图12所示，图中QL表示左眼视图对应的子像素，QR表示右眼视图对应的子像素。以主瓣角满足：
Figure PCTCN2020132891-appb-000020
且主瓣视区内分布16视点为例。在位置1处，像素岛中左眼对应1～8视点，右眼对应9～16视点，在位置2处，左眼对应9～16视点，右眼对应17～24视点。
图13为像素岛显示部分视点图像的示意图，如图13所示，图中QL表示左眼视图对应的子像素，QR表示右眼视图对应的子像素。以主瓣角满足：
Figure PCTCN2020132891-appb-000021
且主瓣视区内分布15视点为例。在位置1处，像素岛中左眼对应1～5视点，右眼对应10～15视点，可以关闭6～9视点位置处的信号。在位置2处，左眼对应6～10视点，右眼对应16～20视点，可以关闭11～15视点位置处的信号。相比于图12所示的显示过程，图13所示的显示过程，可以使每一时刻输入的3D数据量降低为全驱动时的2/3。
尽管已描述了本公开的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开实施例的精神和范围。这样，倘若本公开实施例的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
