本发明涉及显示技术领域，尤指一种3D显示装置。
背景技术
3D显示由于其逼真性已经成为显示领域的一种趋势，正逐步走进人们生活。目前，3D技术可分为裸眼式和眼镜式两大类。眼镜式3D技术需要佩戴专门眼睛，携带不方便，因此平板和手机类产品更多关注裸眼式3D技术。目前裸眼式3D技术主要包括光栅式和透镜式两种方式；其中，透镜式由于一般不能和液晶显示屏或者有机电致发光显示屏工艺兼容，所以面板厂商将重点更多放在利用光栅式实现裸眼3D技术。
光栅式是通过整列的不透光物质限制特定角度的光线，使左眼只能看到左眼需要看到的图像，右眼只看到右眼需要看到的图像，从而产生立体的图像。目前，现有的电致变色光栅的基本结构为五层结构：第一玻璃衬底、第一透明电极层、电致变色层、第二透明电极层，以及第二玻璃衬底；其中，电致变色材料一般为溶液状，第一玻璃衬底和第二玻璃衬底需要进行对盒封装，使电致变色光栅成为3D外挂件，整个封装工艺较复杂，形成的3D显示装置较厚，且由于电致变色光栅作为外挂件，在与显示面板中的各亚像素进行对位时会出现误差，精度不够准确。

具体实施方式
下面结合附图，对本发明实施例提供的3D显示装置的具体实施方式进行详细地说明。
其中，附图中各膜层的厚度和形状不反映3D显示装置的真实比例，目的只是示意说明本发明内容。说明书第一和第二不表示任何以上的优先或排序，仅为了给予不同元件以不同的名称。
本发明实施例提供了一种3D显示装置，如图1所示，包括：显示面板和位于显示面板出光侧的电致变色光栅；其中，该电致变色光栅包括：依次层叠 设置于显示面板的衬底基板001上的第一透明电极层002、电致变色层003、固态电解质层004，以及第二透明电极层005。即该电致变色光栅设置在显示面板的衬底基板的远离液晶的一侧。
在具体实施时，显示面板可以为液晶显示面板、有机电致发光显示面板或其他形式的显示面板，在此不作限定。
在本发明实施例提供的上述电致变色光栅，由于采用固态电解质层，可以代替用现有的上下两层玻璃衬底对电致变色光栅进行封装，避免了复杂的封装工艺，从而实现3D显示装置薄型化，且由于电致变色光栅直接形成在显示面板的衬底基板上，可以使电致变色光栅与显示面板中的各亚像素对位更简单、精准。
在具体实施时，在本发明实施例提供的上述3D显示装置中，固态电解质层的材料有多种选择，具体地，固态电解质层的材料可以为至少一种固态锂盐或含锂的固态聚合物，这些材料具有高离子电导率和透过率，由这些材料形成的固态电解质层可以为电致变色层提供离子，起到传输通道的作用。
在具体实施时，在本发明实施例提供的上述3D显示装置中，该固态锂盐可以包括：LiNbO3和/或LiTaO3；该含锂的固态聚合物可以包括：PEO-LiCF3SO3和/或PEO-LiClO4-Al2O3，合理选择上述固态锂盐或含锂的固态聚合物的材料，可以进一步实现3D显示装置薄型化。对于固态电解质层的具体选择材料，在此不做限定。
在具体实施时，在本发明实施例提供的上述3D显示装置中，为了起到节能的目的，如图2所示，电致变色光栅还包括：在固态电解质层和第二透明电极层之间还可以设置的电致变色存储层006，该电致变色存储层006可以起到存储离子，平衡电荷传输的作用，这样可以实现双稳态工作，即在暗态和透明态都具有稳定的状态，可以使电致变色光栅稳定工作，从而达到节能的目的，且可以提高显示效果。
在具体实施时，在本发明实施例提供的上述3D显示装置中，电致变色存 储层的材料一般为具有可逆氧化还原的物质，用来平衡电荷传输，具体地，该电致变色存储层的材料可以为TiO2、V2O5、CeO2或ZnO其中之一或组合。对于电致变色存储层的具体选择材料，在此不做限定。
在具体实施时，需要说明的是，电致变色存储层的材料和电致变色层的材料的氧化态和还原态相反，即电致变色层的材料失电子时，电致变色存储层的材料得电子；电致变色层的材料得电子时，电致变色存储层的材料失电子。具体地，电致变色层的材料可以分为有机材料和无机材料两类；其中，有机材料包括紫罗精类化合物或聚合物，其中聚合物包括聚苯胺、聚吡咯或聚噻吩；无机材料包括阳极变色材料或阴极变色材料，其中阳极变色材料包括NiO、IrOx、CoO3、Rh2O3或MnO，阴极变色变色材料包括WO3、MoO3、V2O3、NbO3或BiO3。对于电致变色层的具体选择材料，在此不做限定。
在具体实施时，在本发明实施例提供的上述3D显示装置中，显示面板中的亚像素可以采用常规的比例为1∶3结构进行排列，也可以采用非常规的比例1∶3结构进行排列，并结合特殊算法可以实现提高显示装置分辨率的效果，即为了提高3D显示装置的分辨率，显示面板中的各亚像素可以采用虚拟像素的排列方式，且各亚像素可以分为用于显示左眼图像的第一类亚像素和用于显示右眼图像的第二类亚像素；电致变色光栅中由电致变色层所在区域形成的遮光区域与第一类亚像素或第二类亚像素所在区域是一一对应的。
需要说明的是，虚拟像素的排列方式有多种，采用同一种虚拟像素排列方式的各亚像素中第一类亚像素与第二类亚像素所在区域的分配也可以有多种，根据不同的虚拟像素的排列方式，以及不同的第一类亚像素与第二类亚像素所在区域的分配，电致变色光栅的遮光区域的图形会随之改变。下面通过几个具体的实例来举例说明。
在具体实施时，在本发明实施例提供的上述3D显示装置中，一种虚拟像素的排列方式如图3a所示，显示面板中相邻的两个亚像素的颜色不同(图3a中R为红色，G为绿色，B为蓝色)；且各亚像素在行方向和列方向均对齐排 列。例如图3a中一个亚像素存在与该亚像素行相邻的亚像素和列相邻的亚像素，当一个亚像素的颜色为红色R时，与该亚像素行相邻的亚像素的颜色为绿色G，列相邻的亚像素的颜色为蓝色B。
在具体实施时，在本发明实施例提供的上述3D显示装置中，在第一种具体实施方式中，如图3b所示，第一类亚像素1与第二类亚像素2分别为沿列方向排列的不同颜色的亚像素，由于电致变色光栅的遮光区域与第一类亚像素1或第二类亚像素2所在区域是一一对应的，如图3c所示，电致变色光栅100的遮光区域为竖直的条状图形。
在第二种具体实施方式中，如图3d所示，第一类亚像素1与第二类亚像素2分别为沿着对角线AA’或BB’方向排列的相同颜色的亚像素，当第一类亚像素1或第二类亚像素2沿着对角线AA’和BB’方向交替排列，可组成一个折线，由于电致变色光栅的遮光区域与第一类亚像素1或第二类亚像素2所在区域是一一对应的，如图3e所示，电致变色光栅100的遮光区域为折线型的条状图形。
在具体实施时，在本发明实施例提供的上述3D显示装置中，另一种虚拟像素的排列方式如图4a所示，显示面板中相邻的两个亚像素的颜色不同(图4a中R为红色，G为绿色，B为蓝色)；且相邻行亚像素中各亚像素之间在列方向错开半个亚像素的位置，需要说明的是，这里半个亚像素的位置指的并不是严格的1/2个亚像素位置，可以是大于等于1/2个亚像素且小于1个亚像素的位置。例如图4a中一个亚像素存在与该亚像素行相邻的亚像素，左列相邻的亚像素以及右列相邻的亚像素，当一个亚像素的颜色为红色R时，与该亚像素行相邻的亚像素的颜色为绿色G，左列相邻的亚像素的颜色为绿色G，右列相邻的亚像素的颜色为蓝色B。
在具体实施时，在本发明实施例提供的上述3D显示装置中，在第一种具体实施方式中，如图4b所示，第一类亚像素1与第二类亚像素2分别为沿单一对角线即斜向右对角线C’方向排列的不同颜色的亚像素，由于电致变色光栅 的遮光区域与第一类亚像素1或第二类亚像素2所在区域是一一对应的，如图4c所示，电致变色光栅100的遮光区域为向右倾斜的条状图形。
在第二种具体实施方式中，如图4d所示，第一类亚像素1与第二类亚像素2分别为沿单一对角线即斜向左对角线DD’方向排列的不同颜色的亚像素，由于电致变色光栅的遮光区域与第一类亚像素1或第二类亚像素2所在区域是一一对应的，如图4e所示，电致变色光栅100的遮光区域为向左倾斜的条状图形。
在第三种具体实施方式中，如图4f所示，第一类亚像素1与第二类亚像素2分别为沿着对角线EE’或FF’方向排列的不同颜色的亚像素，当第一类亚像素1或第二类亚像素2沿着对角线EE’和FF’方向交替排列，可组成一个折线，由于电致变色光栅的遮光区域与第一类亚像素1或第二类亚像素2所在区域是一一对应的，如图4g所示，电致变色光栅100的遮光区域为折线型的条状图形。
在上述几种具体实施方式中，根据两种不同虚拟像素的排列方式，以及不同的第一类亚像素与第二类亚像素所在区域的分配，电致变色光栅的遮光区域的图形可以有以上几种，都可以有效提高3D显示装置的分辨率，在具体实施时，具体选用哪种实施方式可以根据实际需要进行设计，在此不做限定。当然对3D显示装置的具体实现方式不仅包括上述具体实施方式，还有其他种类，只需满足显示面板中的各亚像素采用虚拟像素的排列方式，且各亚像素分为用于显示左眼图像的第一类亚像素和用于显示右眼图像的第二类亚像素；电致变色光栅的遮光区域与第一类亚像素或第二类亚像素所在区域一一对应即可，在此不作限定。
本发明实施例提供的一种3D显示装置，包括：显示面板和位于显示面板出光侧的电致变色光栅；其中，电致变色光栅包括：依次层叠设置于显示面板的衬底基板上的第一透明电极层、电致变色层、固态电解质层，以及第二透明电极层，由于采用固态电解质层，可以代替用现有的上下两层玻璃衬底对电致 变色光栅进行封装，避免了复杂的封装工艺，从而实现3D显示装置薄型化，且由于电致变色光栅直接形成在显示面板的衬底基板上，可以使电致变色光栅与显示面板中的各亚像素对位更简单、精准。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
