Description

一种集成偏光片和触控功能的盖板及显示装置
本申请要求于2017年10月18日提交中国专利局、申请号为201710971427.X、发明名称为“一种集成偏光片和触控功能的盖板及显示装置”的中国专利申请的优先权,上述专利的全部内容通过引用结合在本申请中。
技术领域
本发明涉及液晶显示技术领域,尤其涉及一种集成偏光片和触控功能的盖板及显示装置。
背景技术
随着人们对柔性触控显示器件和电子产品的强烈需求,传统的液晶显示器(LCD)已不再适用,而柔性的有机发光二极管显示器(OLED)因其更佳的光学性能(尤其是可绕折性)而越来越受到消费者的期待,因此对柔性OLED及柔性触控面板的轻薄性要求越来越严格。
目前市面上大多数以传统的外挂式触控面板为主,并将外挂式触控面板外贴于OLED显示屏上形成完整的触控显示器件,其结构由相互独立的保护盖板、触控感应器、偏光片以及OLED显示屏形成,而各个独立部件之间需要通过光学透明胶(如OCA光学胶或PSA压敏胶)分别逐步贴合在一起,但是这样明显增加了触控显示器件的厚度,不利于现实电子产品的可绕折及柔性化的特性;而将触控面板集成到OLED显示屏内部或表面(如On-cell或In-cell)上,虽然能降低触控显示器件的厚度,但是制程工艺较复杂,还造成OLED良率较低,增加整体成本。
同时,发明人还发现,不管外贴于OLED显示屏上的外挂式触控面板还是集成到OLED显示屏内部或表面上的触控面板均采用ITO(Indium tin oxide,氧化铟锡)形成透明导电电极,但ITO作为一种半导体金属氧化物材质,经过反复绕折后,易产生龟裂而导致电性能破坏。

具体实施方式
下面参考附图对本发明的优选实施例进行描述。
如图1所示,为本发明实施例一中,提供的一种集成偏光片和触控功能的盖板,包括:
线偏光片1;
设置于线偏光片1上的第一硬化层2;
设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及
设置于相位补偿膜3上表面上并用于形成触控感应电极的导电电极层4,且该导电电极层4采用单层结构。
应当说明的是,本发明实施例一中的集成偏光片和触控功能的盖板将传统的偏光片与具有触控功能的导电电极层4集成为一体,无需再单独制作触摸屏,大大简化了生产工艺流程,降低了整体厚度,节约了成本;同时导电电极层4位于传统偏光片的下方,可有效降低导电图案对于外部的可见性,并可以有效降低触控导电层的反射引起的光学雾度偏高的问题,减轻了显示屏的视觉发白现象。
可以理解的是,线偏光片由上TAC(三醋酸纤维素)保护层、PVA(聚乙烯醇)偏光子片和下TAC保护层形成;其中,上下TAC保护层均是用于保护PVA偏光子片,防止PVA偏光子片收缩;而PVA偏光子片经染色、延伸后形成偏光子,将自然光变成偏正光,起到线偏光片的作用。相位补偿 膜3用于使入射光产生相位延迟,产生相应形状的偏振光(如圆偏正光、椭圆偏正光等),从而可以减少表面的反射率,减少外界光线的干扰,达到实现入射光光线补偿功能的目的,且该相位补偿膜3和线偏光片1之间设有将线偏光片1和相位补偿膜3粘合在一起的第一光学胶层5,且使得位于相位补偿膜3上表面上的导电电极层4设置于相位补偿膜3和第一光学胶层5之间,即相位补偿膜3通过第一光学胶层5粘贴在线偏光片3的下方。
为了保护本发明实施例一中的集成偏光片和触控功能的盖板,采用第一硬化层2设置于线偏光片1上方,其第一硬化层2的材质采用氧化硅等无机材质或C/O等有机材质;其中,无机材质形成的第一硬化层2是通过CVD等方法沉积在上TAC保护层1上表面上的,其厚度10nm~1000nm;而有机材质形成的第一硬化层2通常是通过Coating等方法涂覆或者喷溅在线偏光片1上表面上的,其厚度为1um~100um之间。
为了使得相位补偿膜3产生圆偏正光或椭圆偏正光,相位补偿膜3采用1/4相位延迟的相位补偿膜,或采用1/2相位延迟的相位补偿膜。
为了有利于实现柔性触控,降低制作工艺和成本,导电电极层4通常可以由金属网格Metal Mesh、纳米银线、碳纳米管、石墨烯、导电高分子(PEDOT)等耐绕折性较好的导电材料制作而成。
为了达到更高效的目的,特别的,导电电极层4由转印型透明导电薄膜TCTF制作而成;其中,如图2所示,转印型透明导电薄膜包括用于制成触控感应电极的透明感光树脂基质层M以及填充于所述透明感光树脂基质层一表面的纳米导电丝线K;其中,透明感光树脂通常在处于液体胶状或者半固化状态下进行曝光→显影即可制得透明触控感应电极,主要因为透明感光树脂在液体胶状或者半固化状态下具有感光性,而在完全固化状态下不再具有感光性。相较于传统的ITO制程步骤(如上光阻→曝光→显影→蚀刻→剥膜),明显简化了生产流程,降低成本。
当然,为了使得本发明实施例一中的集成偏光片和触控功能的盖板为柔 性盖板,因此还包括塑料基座11,该塑料基座11设置于第一硬化层2和线偏光片1之间,通常为PI或者PET等塑料制作而成,其厚度通常10um~100um之间。
为了进一步减少该塑料基座11与线偏光片1之间的磨损,则设置第二硬化层12,该第二硬化层12设置于塑料基座11与线偏光片1之间。由于第二硬化层12采用与第一硬化层2相同材质、结构及制作工艺,因此在此不再一一赘述。
如图3所示,为本发明实施例二中,提供的另一种集成偏光片和触控功能的盖板,包括:
线偏光片1;
设置于线偏光片1上的第一硬化层2;
设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及
设置于相位补偿膜3下表面上并用于形成触控感应电极的导电电极层4,且该导电电极层4采用单层结构。
其中,线偏光片1和相位补偿膜3之间即便不存在导电电极层4,还是需要通过第一光学胶层5粘合在一起的。
因此,相应于本发明实施例一中的集成偏光片和触控功能的盖板,本发明实施例二中的集成偏光片和触控功能的盖板除了导电电极层4设置的位置不同之外,其它结构及连接关系与本发明实施例一中的集成偏光片和触控功能的盖板均相同,因此除了导电电极层4设置的位置不同之外的其它结构及连接关系具体请参见本发明实施例一中的集成偏光片和触控功能的盖板,在此不再一一赘述。
如图4所示,为本发明实施例三中,提供的又一种集成偏光片和触控功能的盖板,包括:
线偏光片1;
设置于线偏光片1上的第一硬化层2;
设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及

其中,线偏光片1和相位补偿膜3之间即便存在导电电极层4,还是需要通过第一光学胶层5粘合在一起的。
因此,相应于本发明实施例一中的集成偏光片和触控功能的盖板,本发明实施例三中的集成偏光片和触控功能的盖板除了新增一个单层结构导电电极层4设置的位置不同之外,其它结构及连接关系与本发明实施例一中的集成偏光片和触控功能的盖板均相同,因此除了新增一个单层结构导电电极层4设置的位置不同之外的其它结构及连接关系具体请参见本发明实施例一中的集成偏光片和触控功能的盖板,在此不再一一赘述。
如图5所示,为本发明实施例四中,提供的又一种集成偏光片和触控功能的盖板,包括:

设置于线偏光片1上的第一硬化层2;
设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及

其中,集成偏光片和触控功能的盖板还包括由PET或COP材料制作而成的第一透明薄膜层6,该第一透明薄膜层6设置于导电电极层4的下表面上。
此时,第一透明薄膜层6位于相位补偿膜3上方,则第一透明薄膜层6通过第二光学胶层7与相位补偿膜3粘合在一起,而其对应相连的导电电极层4通过第一光学胶层5与线偏光片1粘合在一起。
相应于本发明实施例一中的集成偏光片和触控功能的盖板,本发明实施例四中的集成偏光片和触控功能的盖板在导电电极层4下表面设置了第一透 明薄膜层6,除第一透明薄膜层6的位置及连接方式不同之外,其它结构及连接关系与本发明实施例一中的集成偏光片和触控功能的盖板均相同,因此除第一透明薄膜层6的位置及连接方式不同之外的其它结构及连接关系具体请参见本发明实施例一中的集成偏光片和触控功能的盖板,在此不再一一赘述。

其中,集成偏光片和触控功能的盖板还包括由PET或COP材料制作而成的第一透明薄膜层6,该第一透明薄膜层6设置于导电电极层4的下表面上。
此时,第一透明薄膜层6位于相位补偿膜3下方,则第一透明薄膜层6对应相连的导电电极层4通过第二光学胶层7与相位补偿膜3粘合在一起。应当说明的是,线偏光片1和相位补偿膜3之间即便不存在导电电极层4,还是需要通过第一光学胶层5粘合在一起的。
相应于本发明实施例二中的集成偏光片和触控功能的盖板,本发明实施例五中的集成偏光片和触控功能的盖板在导电电极层4下表面上设置了透明薄膜层6,除第一透明薄膜层6的位置及连接方式不同之外,其它结构及连接关系与本发明实施例二中的集成偏光片和触控功能的盖板均相同,因此除第一透明薄膜层6的位置及连接方式不同之外的其它结构及连接关系具体请参见本发明实施例二中的集成偏光片和触控功能的盖板,在此不再一一赘述。

其中,集成偏光片和触控功能的盖板还包括由PET或COP材料制作而成的第一透明薄膜层6,该第一透明薄膜层6设置在位于相位补偿膜3上方的导电电极层4上。
此时,第一透明薄膜层6位于相位补偿膜3上方,第一透明薄膜层6通过第二光学胶层7与相位补偿膜3粘合在一起,而其对应相连的导电电极层4(即位于相位补偿膜3上方的导电电极层)通过第一光学胶层5与线偏光片1粘合在一起。应当说明的是,位于相位补偿膜3下方的导电电极层4由于没有设置第一透明薄膜层6,此时可以直接与相位补偿膜3相连。
相应于本发明实施例三中的集成偏光片和触控功能的盖板,本发明实施例五中的集成偏光片和触控功能的盖板在位于相位补偿膜3上方的导电电极层4下表面设置了第一透明薄膜层6,除第一透明薄膜层6的位置及连接方式不同之外,其它结构及连接关系与本发明实施例三中的集成偏光片和触控功能的盖板均相同,因此除第一透明薄膜层6的位置及连接方式不同之外的其它结构及连接关系具体请参见本发明实施例三中的集成偏光片和触控功能的盖板,在此不再一一赘述。

设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及
设置于相位补偿膜3上表面上并用于形成触控感应电极的导电电极层4,且该导电电极层4采用由两个单层堆叠而成的双层结构。
其中,双层结构的导电电极层4包括第一电极层41、设置在第一电极层41上的第二透明薄膜层42和设置在第二透明薄膜层42上的第二电极层43,该第一电极层41和第二透明薄膜层42之间通过第四光学胶层9粘合在一起。其中,第二透明薄膜层42由PET或COP材料制作而成。
此时,第二透明薄膜层42位于相位补偿膜3上方,则双层结构的导电电极层4的第二电极层43通过第三光学胶层8与线偏光片1粘合在一起,且对应的第一电极层41直接与相位补偿膜3相连。
相应于本发明实施例八中的集成偏光片和触控功能的盖板,本发明实施例十中的集成偏光片和触控功能的盖板在双层结构的导电电极层4分为第一电极层41和第二电极层42,并在第一电极层41和第二电极层42中新增了第二透明薄膜层42,且第一电极层41和第二透明薄膜层42之间通过第四光学胶层9粘合在一起,除双层结构的导电电极层4的结构及连接关系不同之外,其它结构及连接关系与本发明实施例八中的集成偏光片和触控功能的盖板均相同,因此除双层结构的导电电极层4的结构及连接关系不同之外的其它结构及连接关系具体请参见本发明实施例八中的集成偏光片和触控功能的盖板,在此不再一一赘述。
如图12所示,为本发明实施例十一中,提供的又一种集成偏光片和触控功能的盖板,包括:
线偏光片1;
设置于线偏光片1上的第一硬化层2;
设置于线偏光片1下方并用于增强投射光强度的相位补偿膜3;以及
设置于相位补偿膜3下表面上并用于形成触控感应电极的导电电极层4,且该导电电极层4采用由两个单层堆叠而成的双层结构。
其中,双层结构的导电电极层4包括第一电极层41、设置在第一电极层41上的第二透明薄膜层42和设置在第二透明薄膜层42上的第二电极层43,该第一电极层41和第二透明薄膜层42之间通过第四光学胶层9粘合在一起。其中,第二透明薄膜层42由PET或COP材料制作而成。
此时,第二透明薄膜层42位于相位补偿膜3下方,则双层结构的导电电极层4的第二电极层43通过第五光学胶层10与相位补偿膜3粘合在一起。应当说明的是,线偏光片1和相位补偿膜3之间即便不存在双层结构的导电电极层4,还是需要通过第三光学胶层8粘合在一起的。
相应于本发明实施例十中的集成偏光片和触控功能的盖板,本发明实施例十一中的集成偏光片和触控功能的盖板中双层结构的导电电极层4设置于相位补偿膜3下方,需通过第五光学胶层10与相位补偿膜3粘合在一起,除双层结构的导电电极层4设置位置及与相位补偿膜3连接关系不同之外,其它结构及连接关系与本发明实施例十中的集成偏光片和触控功能的盖板均相同,因此除双层结构的导电电极层4设置位置及与相位补偿膜3连接关系不同之外的其它结构及连接关系具体请参见本发明实施例十中的集成偏光片和触控功能的盖板,在此不再一一赘述。
相应于本发明实施例一至十一中的集成偏光片和触控功能的盖板,本发明实施例十二还提供了一种显示装置,包括具有本发明实施例一至十一中相同结构及连接关系的集成偏光片和触控功能的盖板以及OLED显示屏。应当说明的是,本发明实施例十二中的集成偏光片和触控功能的盖板与OLED显示屏通过光学胶粘合在一起。
由于本发明实施例十二中的集成偏光片和触控功能的盖板与本发明实施例一至十一中集成偏光片和触控功能的盖板具有相同的结构及连接关系,因此在此不再一一赘述。
综上,与传统的偏光片相比,本发明集成触控功能和保护盖板为一体,无需再单独制作触摸屏,大大简化了生产工艺流程,降低了整体厚度,节约了成本;同时导电电极层位于传统偏光片的下方,可有效降低导电图案对于外部的可见性,并可以有效降低触控导电层的反射引起的光学雾度偏高的问题,减轻了显示屏的视觉发白现象;
本发明中触控透明导电电极层的导电材料为柔性的纳米导电丝线,而非传统的透明导电材ITO,因此有利于实现柔性触控,并且制作工艺相对于ITO制作工艺更加简单,降低了成本。
以上所揭露的仅为本发明一种较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明权利要求所作的等同变化,仍属本发明所涵盖的范围。
