Description

三维显示装置 技术领域
本公开涉及显示技术领域，尤其涉及一种三维显示装置。
背景技术
目前，显示屏常见的像素设计是RGB或RGBW设计，即由三个子像素或四个子像素组成一个像素进行显示，其视觉分辨率就是物理分辨率。但是随着客户对显示屏感受要求的提高，面板制作商需要不断增加显示屏的视觉分辨率(PPI)设计。目前，一般采用减小像素尺寸的方式来提高显示屏的物理分辨率。然而，随着像素的尺寸越来越小，制作显示屏的工艺难度会越来越大。
为了提高显示的视觉分辨率，目前已经发展出了一种两个子像素合成一个像素的技术，即虚拟显示(Pentile)技术。该技术的原理是利用人类视觉***中对亮度的分辨率是对色度分辨率的几倍，通过借用相邻子像素，结合与之对应的算法进行显示(也称像素渲染、色彩弥散)。Pentile技术可以使用现有的工艺能力实现高分辨率。
目前，随着立体显示技术的快速发展，对三维显示装置有了越来越大的需求。在实现三维显示的众多技术当中，裸眼三维立体显示由于无需观看者佩戴眼镜而倍受青睐。然而，当现有的针对普通像素设计的实现裸眼立体显示的三维光栅应用在实现虚拟显示的像素结构上，会产生串扰问题以及摩尔纹的问题，极大地影响了三维显示的观看效果。

下面结合附图，对本公开实施例提供的三维显示装置的具体实施方式进行详细地说明。
本公开实施例提供的三维显示装置，如图1所示，包括：由行列 排列的多个子像素01构成的像素结构，以及由多个沿着水平方向周期性排列的条状光栅结构02构成的三维光栅。
具体地，如图2a-2c所示，在每列子像素中，各子像素01对齐排列。在每行子像素中，各子像素01相对于相邻子像素01错开半个子像素，并且与相邻子像素01的颜色各不相同。在图2a-2c中以A、B、C分别表示三种不同的颜色。
参照图1，各条状光栅结构02的延伸方向均相同且相对于水平方向具有预设倾斜角度。每个条状光栅结构02对应各行子像素中至少两个显示不同视点图像的子像素01。
在本公开实施例提供的上述三维显示装置中，通过采用倾斜的条状光栅结构02配合其中在每行子像素中各子像素01相对于相邻子像素01错开半个子像素的像素结构，可以降低同时被相邻的两个条状光栅结构覆盖的子像素的比例，从而降低三维显示时的串扰和摩尔纹，提高三维显示的观看效果。
进一步地，在本公开实施例提供的上述三维显示装置的像素结构中，如图2a-2c所示，在每行子像素中，奇数列上的子像素01对齐排列，并且偶数列上的子像素01对齐排列，以保证像素结构整体为矩形结构。并且，本公开实施例提供的上述三维显示装置的像素结构尤其适用于诸如手机之类的长度大于宽度的竖屏设备在旋转90度后横屏显示三维图像。
根据本公开的实施例，在本公开实施例提供的上述三维显示装置的像素结构中，可以采用虚拟像素结构设计，其中，由相邻的最多两个子像素01组成一个方形像素单元，之后在进行显示时配合虚拟算法，实现虚拟显示。这样在不减小像素尺寸的前提下可以灵活的运用子像素01的选择性开启，以较少的像素显示同样的信息，从而提高显示图像的输出分辨率。具体地，可以如图2a所示，在每列子像素01中由每2个子像素01组成一个方形像素单元(虚线框所示)，各子像素01的纵横比为1∶2。也可以如图2b所示，在每列子像素01中由每1.5个子像素01组成一个方形像素单元(虚线框所示)，各子像素01的纵横比为2∶3。还可以如图2c所示，在每列子像素01中由1个子像素01组成一个方形像素单元(虚线框所示)，各子像素01的纵横比为1∶1。以下以图2b所示的各子像素01的纵横比为2∶3为例进行说明。
根据本公开的实施例，在本公开实施例提供的上述三维显示装置中，当条状光栅结构02的延伸方向相对于水平方向的倾斜角度在[70°，80°]的范围中时，可以具有较佳地降低摩尔纹的效果。进一步地，条状光栅结构02的延伸方向相对于水平方向的倾斜角度在[75°，77.9°]的范围中。例如，条状光栅结构02的延伸方向相对于水平方向的倾斜角度为76°、77°、78°或76.89°。并且，在设计三维光栅中的各条状光栅结构02时，其倾斜方向可以是如图1所示向右倾斜，也可以是向左倾斜，在此不做限定。下面均是以条状光栅结构02向右倾斜为例进行说明。
根据本公开的实施例，在本公开实施例提供的上述三维显示装置的三维光栅中，各条状光栅结构02的侧边缘为沿条状光栅结构02的延伸方向延伸的斜线，且该斜线将与边缘重叠的各子像素01分割成两部分。此时，被分割的各子像素01理论上对应于与所占比例大的部分重叠的条状光栅结构02。例如，如果子像素01被分割成a和b两部分，a部分所占比例大于b部分，则该子像素01对应于与a部分重叠的条状光栅结构02，且属于该条状光栅结构02的视点图像。
在综合考虑低串扰和低摩尔纹的情况下，如图1所示，每个条状光栅结构02在对应各行子像素中的三个分别显示两个视点图像的子像素01时，同时具有较低的三维串扰和较少的摩尔纹。图1中以1和2分别表示两个视点图像。一般在一列子像素中，各子像素01显示的视点图像顺序排列。具体每列子像素01的视点图像排列顺序取决于条状光栅结构02的倾斜角度而有所不同。一般地，像素结构中各子像素01显示的视点图像以每三列子像素为重复单元或以每六列子像素为重复单元。
具体地，在条状光栅结构02的延伸方向相对于水平方向的倾斜角度为76°时，像素结构中各子像素显示的视点图像以每三列子像素为重复单元，该重复单元具体如表1所示。
Figure PCTCN2016098178-appb-000001
表1
根据表1，重复单元可以以像素结构中位于左(右)上角的子像素为起始点。在对应的左上角的第一列中，第1到第3行子像素显示第一视图，第4到12行子像素显示第二视图，第13到21行子像素显示第一视图，即最初3行显示第一视图，接下来9行子像素显示第二视图，再接下来9行子像素显示第一视图，接下来9行子像素显示第二视图，再接下来9行子像素显示第一视图，依此类推至该列结束。
在对应的左上角的第二列中，第1到第9行子像素显示第一视图，第10到18行子像素显示第二视图，第19到27行子像素显示第一视图，即最初9行显示第一视图，接下来9行子像素显示第二视图，再接下来9行子像素显示第一视图，接下来9行子像素显示第二视图，再接下来9行子像素显示第一视图，依此类推至该列结束。
在对应的左上角的第三列中，第1到第6行子像素显示第二视图，第7到15行子像素显示第一视图，第16到24行子像素显示第二视图，即最初6行显示第二视图，接下来9行子像素显示第一视图，再接下来9行子像素显示第二视图，接下来9行子像素显示第一视图，再接下来9行子像素显示第二视图，依此类推至该列结束。
后续每列子像素均依该三列子像素为重复单元，依此排列。
具体地，在条状光栅结构02的延伸方向相对于水平方向的倾斜角度为77°时，像素结构中各子像素显示的视点图像以每三列子像素为重复单元，该重复单元具体如表2所示。
Figure PCTCN2016098178-appb-000002
表2
具体地，在条状光栅结构02的延伸方向相对于水平方向的倾斜角度为78°时，像素结构中各子像素显示的视点图像以每三列子像素为重复单元，该重复单元具体如表3所示。
Figure PCTCN2016098178-appb-000003
表3
具体地，在条状光栅结构02的延伸方向相对于水平方向的倾斜角度为76.89°时，像素结构中各子像素显示的视点图像以每六列子像素为重复单元，该重复单元具体如表4所示。
Figure PCTCN2016098178-appb-000004
表4
进一步地，在本公开实施例提供的上述三维显示装置中的像素结构中，在每列子像素中，相邻两个显示不同视点图像的子像素之一或二者的显示亮度可以设置成低于其他子像素的显示亮度。例如：对于每一列的分别显示视点图像1和视点图像2的相邻的两个子像素，其中的一个或二者以低亮度显示，亮度比例为正常显示时的0％～80％，特别地为50％。如图3所示，由于该两个子像素(由虚线圆圈表示)恰好在每一个条状光栅结构的中间区域(图中虚线为条状光栅结构的中心线)，即该两个子像素横跨条状光栅结构的左右部分，是增加串扰的点，因此降低其显示亮度能明显地减弱三维串扰，从而提升三维显示效果。
根据本公开的实施例，在本公开实施例提供的上述三维显示装置中的三维光栅具体可以为透镜光栅，对应地，组成三维光栅的各条状光栅结构02为透镜结构。可以采用液晶透镜实现其透镜功能。可替换地，在本公开实施例提供的上述三维显示装置中的三维光栅具体可以为狭缝光栅，对应地，组成三维光栅的各条状光栅结构02为条状透光区域和条状遮光区域的组合，即一个条状光栅结构02由一个条状透光区域和一个条状遮光区域组成，且条状透光区域和条状遮光区域的延伸方向与条状光栅结构02的延伸方向一致。
根据本公开的实施例，在本公开实施例提供的上述三维显示装置 中的三维光栅和像素结构的位置关系为：三维光栅可以设置在像素结构的出光侧；或者，当像素结构为液晶像素结构时，三维光栅也可以设置在像素结构的入光侧。
在本公开实施例提供的三维显示装置中，由行列排列的多个子像素构成像素结构。在每列子像素中，各子像素对齐排列。在每行子像素中，各子像素相对于相邻子像素错开半个子像素，并且与相邻子像素的颜色各不相同。对应的三维光栅包括多个沿着水平方向周期性排列的条状光栅结构，其中，各条状光栅结构的延伸方向均相同且相对于水平方向具有预设倾斜角度。每个条状光栅结构对应各行子像素中至少两个显示不同视点图像的子像素。通过采用倾斜的条状光栅结构配合其中在每行子像素中各子像素相对于相邻子像素错开半个子像素的像素结构，可以降低同时被相邻的两个条状光栅结构覆盖的子像素的比例，从而降低三维显示时的串扰和摩尔纹，提高三维显示的观看效果。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开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。
