Description

电致变色光栅及其制备方法、3D显示装置 技术领域
本发明的实施例涉及显示技术领域，尤其是一种电致变色光栅及其制备方法、3D显示装置。
背景技术
3D显示功能已经广泛应用于显示装置中，实现3D显示的方法包括快门式、偏光式、光栅式等，其中快门式和偏光式均需要佩戴眼镜来观看，而光栅式可直接裸眼观看。
现有技术中利用电致变色溶液制备2D/3D切换的光栅，即在两个透过导电膜之间设置电致变色溶液，通过控制电致变色溶液形成黑白条间隔的光栅。
如图1所示，现有技术中的3D光栅是通过设在第一基板11和第二基板12之间的阻隔层13将电致变色溶液14分隔在相应的网格内，施加电压后电致变色溶液14发生变色形成光栅从而起到遮光作用。一般地，在第一基板11上依次制备ITO透明电极、阻隔层13，电致变色溶液14滴注在阻隔层13形成的网格内；在第二基板12上制备一层ITO透明电极；两层基板对合后形成光栅。滴注在阻隔层13网格内的电致变色溶液14完全依靠第二基板12与第一基板11贴合后进行分隔。由于贴合后阻隔层13与第二基板12之间会存在缝隙，因此这种光栅无法将电致变色溶液14完全分隔在相应的网格内，导致其他需要透光的网格也会渗有电致变色溶液，加电后也会发生变色，从而影响3D显示面板的3D显示效果。另外，现有技术中采用的电致变色溶液以及较厚的阻隔层都会对显示面板发出的光发生严重的折射和散射，从而影响2D显示的效果。
发明内容
为了解决上述现有技术中存在的问题，本发明提出一种电致变色光栅及其制备方法、3D显示装置，采用无机电致变色材料形成电致变色图形，该图形在一种电压情况下完全透明，不会影响2D显示效果，在另一种电 压情况下，无机电致变色材料发生变色，有图形的区域产生遮光效应，从而起到光栅的作用，设置有该光栅的显示面板能够实现裸眼3D显示。
根据本发明的一方面，提出一种电致变色光栅，包括：
基板；
多个条状的第一透明电极，以相等的预定间距平行地分布在所述基板上；以及
多个离子存储层、多个电致变色层和多个条状的第二透明电极，
其中，在每个所述第一透明电极上依次形成一个离子存储层、一个电致变色层和一个第二透明电极，所述电致变色层被配置成当在所述第一透明电极和第二透明电极上施加不同的驱动电压的情况下从透明状态转换成遮光状态。
在一种实施例中，所述电致变色层由无机电致变色材料制成。
在一种实施例中，所述电致变色层由氧化铱IrO3、氧化钨WO3或氧化钼MoO3制成。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实 施例，并参照附图，对本发明进一步详细说明。
在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
根据本发明的一方面的实施例，提出一种电致变色光栅，如图2所示，所述电致变色光栅包括：基板1、多个条状的第一透明电极2、多个离子存储层3、多个电致变色层4和多个条状的第二透明电极5。多个条状的第一透明电极1以相等的预定间距平行地分布在所述基板1上。在每个第一透明电极2上依次形成一个离子存储层3、一个电致变色层4和一个第二透明电极5，所述电致变色层被配置成当在第一透明电极2和第二透明电极5上施加不同的驱动电压的情况下从允许光束透过的透明状态转换成阻止光束透过的遮光状态从透明状态转换成遮光状态。这样每个第一透明电极2、以及依次形成在该第一透明电极2上的离子存储层3、电致变色层4和第二透明电极5形成以相等的所述预定间距平行地分布的阻隔层。在本发明实施例的电致变色光栅中，由于阻隔层以相等的预定间距平行地形成在基板1上，因此，所述阻隔层形成的排布间距就成为电致变色层4的排布间距。相邻两个阻隔层之间的预定间距由观察视点的数量、显示面板的像素尺寸和瞳孔间距来决定，如下式所示：
Figure PCTCN2014087680-appb-000001
其中，f表示所述电致变色光栅的排布间距，n表示视点数量，p表示与所述电致变色光栅匹配的显示面板的亚像素的宽度，e表示瞳孔间距。
可选地，利用光刻等构图工艺形成各膜层的图形。
可选地，所述基板1可以由玻璃、硅片、石英、塑料以及硅片等材料中的任一种制成，例如由玻璃制成。
在一种示例性实施例中，所述第一透明电极2和所述第二透明电极5均由透明导电材料制成。所述透明导电材料包括透明金属薄膜、透明金属氧化物薄膜、非金属氧化物薄膜以及导电性颗粒分散铁电材料等。薄膜的形式包括单层膜、二层膜、多层膜或复层膜、无掺杂型、掺杂型和多元素 型。例如，所述透明导电材料包括金属氧化物薄膜，比如氧化铟锡(ITO)薄膜。
可选地，所述第一透明电极2和所述第二透明电极5的厚度为0.02～0.50um。例如，可以利用沉积或溅射成膜等半导体工艺分别形成用于形成第一透明电极的第一透明电极材料层和用于形成第二透明电极的第二透明电极材料层。
其中，所述离子存储层3用于存储和提供电致变色所需要的离子，维持电荷平衡。离子存储层3由五氧化二钒V2O5或二氧化钛TiO2等材料制成。例如，离子存储层3由五氧化二钒V2O5制成，五氧化二钒V2O5具有良好的离子存储性能，具有半导体特性和层状结构，有利于离子存储和传输，以维持电致变色层中的电荷平衡。离子存储层3的厚度为0.2～1um。可以利用溅射成膜等半导体工艺形成离子存储层3。
在一种示例性实施例中，电致变色层4由氧化铱IrO3、氧化钨WO3或氧化钼MoO3等无机电致变色材料制成。电致变色层4的厚度为1.5～10um。例如，利用沉积或溅射成膜等半导体工艺形成电致变色材料层。
根据本发明实施例的电致变色光栅，由于电致变色层4由固态的膜形成，位于两个相邻阻隔层中的电致变色层彼此物理隔离，一个阻隔层中的电致变色层不会对其它透光区域的透光性能产生影响，从而提高了包括这种电致变色光栅的3D显示装置的3D显示效果。
本发明实施例的电致变色光栅还包括驱动电路(未示出)，所述驱动电路与所述第一透明电极2和第二透明电极5连接，以提供用于所述电致变色层4的驱动电压。可选地，所述电致变色光栅可以采用直流驱动。例如，所述电致变色光栅的驱动电压为2～20V。需要注意的是，不同电致变色材料的驱动电压存在一定的差异，因此，在实际应用中，还需要根据不同电致变色材料的特性来确定驱动电压的具体范围。
在本发明的一种实施例中，所述电致变色光栅中的电致变色层4最初是透光的。在对所述电致变色光栅施加电场驱动后，电致变色层4中的电致变色材料发生变色，例如，变为具有遮光效果的黑色，形成遮光图形，起到光栅的作用，其中发生变色的电致变色材料的光学浓度(OD)为2～3，可见光透过率为0.1～1％。在该实施例中，所述电致变色材料在未施加电 压或者所施加的电压低于一个预定值时呈允许光束透过的透明状态，在所施加的电压大于该预定值时呈阻止光束透过的遮光状态。当然，对于未施加电压或者所施加的电压低于一个预定值时呈遮光状态，在所施加的电压大于该预定值时呈透明状态的电致变色材料也可以应用于本发明实施例的电致变色光栅。例如，在一种实施例中，电致变色层在施加第一电压值时呈透明状态，施加第二电压值后呈遮光状态的电致变色材料。
另外，在一种实施例中，在所述驱动电压为(2～20V)范围内，随着驱动电压的增大，处于遮光图形处的电致变色层的光学浓度增大，可见光透过率降低，逐渐从透明状态转换成遮光状态。
需要说明的是，也可以采用其他驱动方式对于所述电致变色光栅进行驱动，本发明对于电致变色光栅的驱动方式不作特殊限定，只要能够对于所述电致变色光栅进行驱动，使得遮光图形相应位置处的电致变色材料发生色变即可。
根据本发明实施例的电致变色光栅，电致变色层在未施加电压或者所施加的电压低于一个预定值时呈透明状态，在施加的电压大于该预定值时呈遮光状态。这样，如图4所示，当对所述电致变色光栅施加一定的外加电压时，处于遮光图形相应位置处的电致变色层的材料发生恒定变色，变成遮光状态，比如变为黑色。此时，显示面板7发出的光线部分被变为黑色的部分遮挡，部分光线从没有设置电致变色层的遮光图形之间的间隙处透出，从而起到光栅的作用。在此情况下，将显示面板所显示的左右眼图像分别投射到显示面板7前方的左眼视区和右眼视区，观看者的左右眼分别位于左右眼视区内时即可以观看到3D图像，从而可以实现裸眼3D显示。如图3所示，当去除外加电压或者所施加的电压小于预定值时，处于遮光图形相应位置处的电致变色层的材料恢复为透明状态，显示面板7发出的光线全部透出，没有任何遮挡，从而实现2D显示。因此，使用具有根据本发明上述任一实施例的电致变色光栅的显示装置，能够很方便地实现裸眼3D显示，并且很方便地在裸眼3D显示与2D显示状态之间进行切换。另外，本发明上述任一实施例的电致变色光栅的遮光图形位置固定，能够将遮光区和透光区严格的区分开来，使得遮光区和透光区互相之间不存在任何干扰，从而对于2D显示的效果不会产生任何的影响，为用户带 来了极佳的使用体验。
在本发明一实施例中，所述显示面板7为普通2D显示屏，例如可以是有机发光二极管(organic Light Emitting Diode(OLED))显示面板、薄膜晶体管液晶(Thin Film Transistor Liquid Crystal Display(TFT-LCD))显示面板、或者主动矩阵有机发光二极管(Active Matrix Organic Light Emitting Diode(AMOLED))显示面板。
根据本发明的另一方面，还提出一种3D显示装置，如图4所示，所述3D显示装置包括显示面板7和设置在所述显示面板上的上述任一实施例所述的电致变色光栅。
在一种实施例中，所述3D显示装置还包括隔垫玻璃8，所述隔垫玻璃8位于所述电致变色光栅与显示面板7之间。
在一种实施例中，所述显示面板7为OLED显示面板，并且所述电致变色光栅位于所述OLED显示面板的出光侧。在另一种实施例中，所述显示面板7为液晶显示面板，并且所述电致变色光栅位于用于向所述液晶显示面板提供光的背光源(未示出)与所述液晶显示面板之间，或所述电致变色光栅位于所述液晶显示面板的出光侧。
本发明所述的显示装置可以为，液晶电视、液晶面板、OLED电视、OLED面板、手机、笔记本或导航仪等装置。
根据本发明的再一方面的实施例，还提出一种电致变色光栅的制备方法，所述制备方法包括以下步骤：
在基板1上依次形成第一透明电极材料层、离子存储材料层、电致变色材料层和第二透明电极材料层；以及
采用构图工艺将所述第一透明电极材料层、离子存储材料层、电致变色材料层和第二透明电极材料层分成在平行于基板的方向上以相等的预定间距平行分布、在垂直于基板1的方向上依次布置的多个第一透明电极2、多个离子存储层3、多个电致变色层4和多个第二透明电极5。在本发明一实施例中，通过形成第一透明电极材料层、离子存储材料层、电致变色材料层和第二透明电极材料层之后，利用一步构图工艺得到所述第一透明电极2、离子存储层3、电致变色层4和第二透明电极4。
当然，在形成所述第一透明电极、离子存储层、电致变色层和第二透 明电极时，也可以采取每形成一材料层之后就进行一次构图工艺的方式，或者其他可能的方式。需要说明的是，本发明对于各膜层的具体形成方式不作具体的限定，任何合理的、能够形成各膜层的方式都落入本发明的保护范围内。
在一种实施例中，形成多个所述第一透明电极2、多个离子存储层3、多个电致变色层4和多个第二透明电极5的步骤包括以下步骤：
在所述第二透明电极材料层上涂布光刻胶6；
采用具有以相等的预定间距平行布置的多个图形的掩膜板(未示出)对光刻胶6进行曝光；
对于经过曝光后的光刻胶进行显影处理；
对所述第一透明电极材料层、离子存储材料层、电致变色材料层和第二透明电极材料层进行刻蚀，露出位于刻蚀部位的基板1，使得所述第一透明电极材料层和第二透明电极材料层分别形成等间距平行布置的多个第一透明电极2和多个第二透明电极4；
去除位于最上层的光刻胶。这样每个第一透明电极2、以及依次形成在该第一透明电极2上的离子存储层3、电致变色层4和第二透明电极5形成以相等的所述预定间距平行地分布的阻隔层。图5A-5J是根据本发明一实施例的电致变色光栅的制备工艺的示意图。如图5A-5J所示，对于该实施例，电致变色光栅的制备方法包括以下步骤：
在基板1上形成第一透明导电层，如图5A和图5B所示；
在第一透明导电层2上形成离子存储材料层3，如图5C所示；
在离子存储材料层3上形成电致变色材料层4，如图5D所示；
在电致变色材料层4上形成第二透明导电层，如图5E所示；
在所述第二透明导电层上涂布光刻胶6，如图5F所示；
采用具有以相等的预定间距平行布置的多个图形的掩膜板(未示出)对光刻胶进行曝光，如图5G所示；
对经过曝光后的光刻胶进行显影处理，如图5H所示；
对第一透明导电层、电致变色层和第二透明导电层进行刻蚀，露出位于刻蚀部位的基板1，使得第一透明电极材料层和第二透明电极材料层分别形成等间距平行布置的多个第一透明电极2和多个第二透明电极5；这 样，形成在基板1上的每个阻隔层依次包括第一透明电极1、离子存储层3、电致变色层4和第二透明电极5，如图5I所示；
剥离位于最上层的光刻胶，形成本发明实施例的电致变色光栅，如图5J所示。
上述制备方法中，光刻胶涂布、曝光、显影、刻蚀和剥离等工艺与现有的显示器件的生产工艺相似，在此不作赘述。
这样，通过成膜、曝光、显影、刻蚀、剥离等构图工艺后，就形成了具有由阻隔层限定成的规则排布的遮光图形的电致变色光栅。如图4所示，对于得到的电致变色光栅施加电场驱动后，处于遮光图形相应位置处的电致变色层的材料由无色透明转变成黑色，从而使显示面板发出的光线部分被变为黑色的部分遮挡，而所述遮光图形之间的间隙处没有设置电致变色材料。从显示面板发出的光束的一部分从遮光图形之间的间隙处透出，将显示面板显示所显示的左右眼图像分别投射到显示面板前方的左眼视区和右眼视区，观看者的左右眼分别位于左右眼视区内时即可以观看到3D图像，最终实现裸眼3D显示。
可选地，所述电致变色光栅可以采用例如为2～20V的直流电压驱动。随着驱动电压的增大，处于遮光图形处的电致变色层的光学浓度增大，可见光透过率降低，逐渐从透明状态转换成遮光状态。
如图3所示，当去除外加电压时，处于遮光图形相应位置处的电致变色层的材料恢复为透明状态，显示面板7发出的光线全部透出，没有任何遮挡，实现2D显示。
因此，使用具有根据本发明任一实施例制得的电致变色光栅的显示装置，能够很方便地实现裸眼3D显示，并且很方便地在裸眼3D显示与2D显示状态之间进行切换。另外，根据本发明上述任一实施例制得的电致变色光栅的遮光图形位置固定，能够将遮光区和透光区严格的区分开来，使得遮光区和透光区互相之间不存在任何干扰，从而对于2D显示的效果不会产生任何的影响，为用户带来了极佳的使用体验。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修 改、等同替换、改进等，均应包含在本发明的保护范围之内。
