Description

3D面板及其制备方法和具有所述3D面板的3D显示装置
本申请要求于2014年9月30日递交的、申请号为201410520459.4、发明名称为“一种3D面板及其制备方法、3D显示装置”的中国专利申请的优先权，其全部内容通过引用并入本申请中。
技术领域
本发明涉及3D显示技术领域，尤其涉及一种主动式光栅3D面板及其制备方法和具有所述3D面板的3D显示装置。
背景技术
立体显示(即，三维(3D)显示)已经成为显示领域的一种趋势。立体显示的基本原理是视差产生立体效果，也就是说，使人的左眼看到左眼图片，右眼看到右眼图片，其中，左右眼图片为有视差的一对立体图像对。
实现立体显示的一种方法是采用串行式，即在第一时刻，显示器显示左眼画面，此时只让观看者的左眼看到显示画面；第二时刻，显示器显示右眼画面，只让观看者的右眼看到显示画面，利用图像在人眼视网膜的暂留性，使人感觉到是左右眼同时看到了左右眼画面，从而产生立体的感觉。
另外一种实现立体显示的方式是并行式，即在同一时刻，显示器上一部分像素显示左眼画面的内容，一部分像素显示右眼画面的内容，通过光栅、偏光眼镜等方式使一部分像素的显示只能被右眼看到，另一部分只能被左眼看到，从而产生立体的感觉。
对于需要佩戴3D眼镜的3D显示模式，由于3D眼镜容易丢失、损坏，观看人数过多时不方便使用、单凭3D显示器无法呈现立体影像等原因，该显示模式渐渐无法迎合人们对于3D显示的需求。对于裸眼3D显示模式，例如光栅式裸眼3D显示装置，由于是将光栅直接设置在显示面板中而无需佩戴3D眼睛，观看起来更便利，因此受到越来越多的关注。
发明内容

在一实施例中，所述第一信号电极和第二信号电极为多组条状电极，且所述第一信号电极的条状电极与第二信号电极的条状电极的排列方向相错。
在一具体实施例中，作为所述第一信号电极的多组条状电极均匀排布且具有第一周期，作为所述第二信号电极的多组条状电极均匀排布且具有第二周期，所述第一周期不同于所述第二周期。
在一优选实施例中，所述第一信号电极的多组条状电极之间的间距大于等于10微米，所述第二信号电极的多组条状电极之间的间距大于等于10微米。

在一实施例中，所述第一公共电极、第一信号电极、第二公共电极和第二信号电极均由透明导电材料制成。
在一实施例中，所述第一公共电极和第二公共电极为面状电极。
在一实施例中，所述3D面板还包括：信号控制模块，所述信号控制模块用于当第一或第二基板的视点选通时，使相应基板的信号电极引线使能。当所述第一基板作为工作电极时：所述第一公共电极引线悬空，第一信号电极引线接入信号，并且第二公共电极引线和第二信号电极引线均接入公共电极信号，第一基板实现光栅功能；当第二基板作为工作电极时：第二公共电极引线悬空，第二信号电极引线接入信号，并 且第一公共电极引线和第一信号电极引线均接入公共电极信号，第二基板实现光栅功能。
根据本发明实施方式的另一方面，还提出一种3D显示装置，其包括如上所述的3D面板。

在本发明一实施例中，所述第二基板从下至上依次包括：第二衬底基板1′、第二公共电极2′、第二公共电极引线3′、第三绝缘层4′、第二信号电极引线5′、第四绝缘层6′和第二信号电极7′，其中：
所述第二衬底基板1′的制作材料可以为玻璃、硅片、石英、塑料以及硅片等材料。
所述第二公共电极2′和第二信号电极7′均由透明导电材料制成，所述透明导电材料可以为透明金属薄膜、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材料，薄膜的形式可以为单层膜、二层膜、多层膜或复层膜、无掺杂型、掺杂型和多元素型。优选地，所述透明导电材料为金属氧化物薄膜，比如氧化铟锡(ITO)薄膜。

所述第四绝缘层6′上形成有多个过孔，以对所述第二信号电极引线5′与第二信号电极7′形成部分隔离，其中，所述多个过孔露出所述信号电极引线5′的部分区域。所述第二信号电极7′通过所述过孔与所述第二信号电极引线5′电连接。
其中，所述第三绝缘层4′和第四绝缘层6′均由透明绝缘材料制成。
在本发明一实施例中，所述第二公共电极引线3′、第二信号电极引线5′均呈框形，且在所述第二衬底基板1′的一侧设有信号接入部。本领域技术人员应当了解，所述第二公共电极引线3′和第二信号电极引线5′的信号接入部的设置位置相近(如 图3D′所示)是为了信号接入的方便，其对于本发明并不构成限制。
进一步地，所述第二公共电极引线3′位于所述第二衬底基板1′的***(如图3B′所示)，所述第二信号电极引线5′位于所述第二公共电极引线3的内侧(如图3D′所示)。
当然，所述第二公共电极引线3′和第二信号电极引线5′也可以为其他形状，只要其能够分别与所述第二公共电极2′和第二信号电极7′实现电连接即可。
在本发明一实施例中，所述第二公共电极2′为面状电极，所述第二信号电极7′为多组条状电极。

进一步地，所述第一基板和第二基板的结构相同，在结构相同的第一基板和第二基板以信号电极相对的方式贴合在一起之后，所述3D面板以第一基板与第二基板之间的中心线为轴线成对称图形。在该实施例中，由于所述第一基板和第二基板的结构相同，因此，在制备所述第一基板和第二基板时，比如在形成公共电极引线和信号电极引线，以及其它相同的图形设计时，均可使用同一掩模版，所述掩模版的上述共用设计可以实现降低3D面板生产成本的效果。
在上述实施例中，所述第一信号电极7和第二信号电极7′接入信号的使能时间不同，比如第一信号电极7和第二信号电极7′接入信号的时间相错，这样，通过对于第一基板和第二基板的信号切换，就能够实现3D面板视点数在物理层次上的切换，也可以用来实现同一个3D面板兼容两种不同分辨率的液晶面板，即实现两种3D显示器共用一种3D面板的目的，最终实现降低开发成本的经济效益。
在本发明一实施例中，所述3D面板还包括信号控制模块，用于当第一或第二基板的视点选通时，使相应基板的信号电极引线使能，即使相应基板的信号电极引线接入信号。具体地，当第一基板的视点选通时，即所述第一基板作为工作电极时：第一 公共电极引线3悬空，第一信号电极引线5接入信号；第二公共电极引线3′和第二信号电极引线5′均接入公共电极信号，此时，第一基板实现光栅功能。当第二基板的视点选通时，即所述第二基板作为工作电极时：第二公共电极引线3′悬空，第二信号电极引线5′接入信号；第一公共电极引线3和第一信号电极引线5均接入公共电极信号，此时，第二基板实现光栅功能。如此，就可以根据实际应用的需要对于3D面板的视点数进行调整。另外，由于本发明3D面板的两侧基板上的电极均能够独立进行控制，通过切换上下基板的信号，能够实现上下基板光栅电极作用的切换，从而提高了3D面板的应用范围，增强了3D面板的兼容性和多功能性。
根据本发明的另一方面，还提出一种3D显示面板，包括如上所述的3D面板、隔离玻璃8和LCD面板9，如图2所示。
根据本发明的另一方面，还提出一种3D显示装置，包括如上所述的3D面板。

可选地，所述第一衬底基板1的制作材料可以为玻璃、硅片、石英、塑料以及硅片等材料。

其中，可通过淀积等工艺形成所述第一导电层，通过曝光、刻蚀等构图工艺形成所述第一公共电极引线3。
在本发明一实施例中，所述第一公共电极引线3呈框形，且在所述第一衬底基板1的一侧设有信号接入部。
当然，所述第一公共电极引线3也可以为其他形状，只要其能够与所述第一公共 电极2实现电连接即可。
在所述第一公共电极引线3上形成第一绝缘层4，以隔离所述第一公共电极引线3和第一信号电极引线5，如图3C所示，其中，所述第一绝缘层4由透明绝缘材料制成，因此在图3C中未显示出来；
其中，可通过沉积等工艺形成所述第一绝缘层4。
在所述第一绝缘层4上形成第二导电层，并通过构图工艺形成第一信号电极引线5，如图3D所示；
其中，所述第二导电层由导电材料制成，优选地，所述导电材料为金属材料。
其中，可通过淀积等工艺形成所述第二导电层，通过曝光、刻蚀等构图工艺形成所述第一信号电极引线5。
在本发明一实施例中，所述第一信号电极引线5亦呈框形结构，并在所述第一公共电极引线3信号接入部的同一侧亦设有信号接入部，本领域技术人员应当了解，所述第一公共电极引线3和第一信号电极引线5的信号接入部的设置位置相近是为了信号接入的方便，其对于本发明并不构成限制。
相似地，所述第一信号电极引线5也可以为其他形状，只要其能够与第一信号电极实现电连接即可。
在所述第一信号电极引线5上形成第二绝缘层6，并在所述第二绝缘层6上形成多个过孔，以对所述第一信号电极引线5与第一信号电极7形成部分隔离，其中，所述多个过孔露出所述第一信号电极引线5的部分区域，如图3E所示，其中，所述第二绝缘层6由透明绝缘材料制成，因此在图3E中未显示出来；
其中，可通过沉积等工艺形成所述第二绝缘层6，通过刻蚀等工艺形成过孔。
在所述第二绝缘层6上形成第一信号电极层，并通过构图工艺形成第一信号电极7，所述第一信号电极7通过所述过孔与所述第一信号电极引线5电连接，由此得到第一基板，如图3F所示。
其中，所述第一信号电极层7由透明导电材料制成，所述透明导电材料可以为透明金属薄膜、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材料，薄膜的形式可以为单层膜、二层膜、多层膜或复层膜、无掺杂型、掺杂型和多元素型。优选地，所述透明导电材料为金属氧化物薄膜，比如氧化铟锡(ITO)薄膜。
在本发明一实施例中，所述第一信号电极7为多组条状电极，每组条状电极通过 相应的过孔与所述第一信号电极引线电连接，进一步地，所述多组条状电极斜向放置。在一优选实施例中，所述第一信号电极7的多组条状电极均匀排布且具有第一周期。
按照上述步骤得到第二基板，如图3A′、图3B′、图3C′、图3D′、图3E′、图3F′所示，只是在制作第二基板的第二信号电极7′时，需要注意所述第二信号电极7′的多组条状电极的排列方向与所述第一信号电极的多组条状电极的排列方向相错，例如如图3F和3F′所示，两者倾斜方向不同。在一优选实施例中，所述第二信号电极7′的多组条状电极均匀排布且具有不同于第一周期的第二周期。另外，所述第一信号电极的多组条状电极之间的间距大于等于10微米所述第二信号电极的多组条状电极之间的间距大于等于10微米。
将所述第一基板与第二基板的边缘贴合在一起，在所述第一基板与第二基板之间填充液晶，形成所述3D面板。
进一步地，所述第二基板的结构与所述第一基板的结构相同，在将结构相同的第一基板和第二基板以信号电极相对的方式贴合在一起之后，所述3D面板以第一基板与第二基板之间的中心线为轴线成对称图形，在该实施例中，由于所述第一基板和第二基板的结构相同，因此，在所述第二基板上形成第二公共电极引线3′和第二信号电极引线5′，以及其它相同的图形设计时，均可与所述第一基板共用同一掩模版，掩模版的上述共用设计可以实现降低3D面板生产成本的效果。
在本发明一实施例中，使用TN模式液晶、球状隔垫物、偏光片等必要材料贴合所述第一基板与第二基板。根据本发明一实施例制得的3D显示面板的截面图如图4所示，图4中，所述第一基板和第二基板的公共电极引线、信号电极引线通过各向异性导电胶分别连接柔性电路板FPC，第一基板和第二基板之间的两个黑色区域为封框胶。
目前主动式光栅的3D显示面板的常规设计只有一种周期性光栅，所以只能兼容一种液晶面板的一种视点数显示，这样就为用户的使用、厂商的生产带来不便。根据上述技术方案制得的3D面板，其上下基板，即第一基板和第二基板上均形成有公共电极和信号电极，但是第一基板和第二基板上的信号电极的使能时间相错，即所述第一基板和第二基板上的信号电极接入信号的时间相错，这样通过对于第一基板和第二基板的信号切换，就能够实现3D面板视点数在物理层次上的切换，也可以用来实现同一个3D面板兼容两种不同分辨率的液晶面板，即实现两种3D显示器共用一种3D 面板的目的，最终实现降低开发成本的经济效益。
根据上述技术方案制得的3D面板，当第一或第二基板的视点选通时，相应基板的信号电极引线使能，即使相应基板的信号电极引线接入信号，具体地，当第一基板的视点选通时，即当所述第一基板作为工作电极时：第一公共电极引线悬空，第一信号电极引线接入信号，并且第二公共电极引线和第二信号电极引线均接入公共电极信号，此时，第一基板实现光栅功能。当第二基板的视点选通时，即当所述第二基板作为工作电极时：第二公共电极引线悬空，第二信号电极引线接入信号，并且第一公共电极引线和第一信号电极引线均接入公共电极信号，此时，第二基板实现光栅功能。如此，就可以根据实际应用的需要对于3D面板的视点数进行调整。另外，由于本发明3D面板的两侧基板上的电极均能够独立进行控制，通过切换上下基板的信号，能够实现上下基板光栅电极作用的切换，从而提高了3D面板的应用范围，增强了3D面板的兼容性和多功能性。
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。
