具体的,柔性显示器包括柔性显示面板10及依次层叠于柔性显示面板10表面的导接层20、绝缘层30及触控电极层40。柔性显示面板10用于实现柔性显示。导接层20、绝缘层30及触控电极层40用于实现柔性触控感应。因此,所述柔性显示器可以实现柔性触控显示。本实施例中,所述柔性显示面板10包括依次层叠设置的柔性衬底12、阵列基板层13、有机发光层14及封装层15。阵列基板层13用于驱动柔性显示器。有机发光层14包括阵列排列的数个子像素11,且每相邻两个子像素11之间形成间隔区域。导接体21正对于两个相邻的子像素11的间隔区域内,这样当有机发光层14进行发光时,可以避免导接体21遮住光源而减小柔性显示器的发光亮度。所述封装层15用于保护柔性显示面板10避免受到水汽、氧气、灰尘及其他外界环境的影响。在其他实施例中,所述柔性显示面板10还包括第一缓冲层(图未示)。所述第一缓冲层设于所述柔性衬底12上。所述第一缓冲层的材料可以为但不仅于为SiO

本实施例中,在导接层20的表面设有绝缘层30,绝缘层30覆盖导接体21。绝缘层30的材质为SiO
2或者SiNx,且绝缘层30为透明薄膜,使得子像素11发光的光能够透过绝缘层30。绝缘层30既能够保护柔性显示面板10避免受到水汽、氧气、灰尘及其他外界环境的影响,也能够更有效地避免触控面板的电压信号对柔性显示面板10的阵列基板层13的电学特性的影响。此外,通过绝缘层30及导接体21的配合还能够在每两个触控感应电极41的电连接下实现每两个触控驱动电极42的电连接,或者在每两个触控驱动电极42的电连接下实现每两个触控感应电极41的电连接。在其他实施例中,所述绝缘层30的材料也可以为SiO

其中,所述绝缘层30内设有多个间隔设置的过孔31,所述导接体21的两端穿过所述过孔31连接于所述触控电极层40。具体的,过孔31的位置设于导接体21的两端。当触控驱动电极42在同一层电连接时,通过导接体21的两端穿过所述过孔31电连接每两个触控感应电极41;当触控感应电极41在同一层电连接时,通过导接体21的两端穿过所述过孔31电连接每两个触控 驱动电极42。本实施例中,在每个导接体21的两端各设有两个过孔31。每端设有两个过孔31可以保证每两个触控感应电极41或者每两个触控驱动电极42有效电连接,避免因其中一个过孔31断路而导致两个触控感应电极41或者每两个触控驱动电极42发生断路。在其他实施例中,每个导接体21的两端也可以分别设有一个或者三个以上的过孔31,具体根据实际情况设置。
其中,绝缘层30设有多个应力缓冲孔32,子像素11正对于应力缓冲孔之内。应力缓冲孔32用于当柔性显示器在发生弯折时能够有效地降低柔性显示器的应力,避免触控电极层40发生断裂而发生断路现象,也使得柔性显示器实现柔性化,避免OLED层发生损伤。本实施例中,所述过孔31与所述应力缓冲孔32通过刻蚀工艺同时形成。这样,不仅达到实现过孔31连接每两个触控感应电极41或者每两个触控驱动电极42的同时,还能够实现降低柔性显示器的应力,避免触控电极层40发生断裂而发生断路现象。此外,应力缓冲孔32的形成不增加额外的工艺步骤。
如图2所示,在绝缘层30的表面上形成触控电极层40,且同一行的触控感应电极41连接形成一感应电极链,同一列的触控驱动电极42连接形成一驱动电极链,触控感应电极链与触控驱动电极链交叉绝缘设置。本实施例中,触控电极层40是通过在绝缘层30上沉积一层导电材料,并经图案化后形成的电极走线。所形成的触控电极层40为网状结构。当所述电极走线正对所述间隔区域内时,可以避免电极走线遮住子像素11的发光,从而增加柔性显示器的发光亮度。在其他实施例里,触控电极层40也可以设计为透明的薄膜导电材料,使得子像素11的发光可以透过触控电极层40,保证柔性显示器的发光亮度。具体根据实际情况设计。
具体的,触控感应电极41正对于子像素11的间隔区域之内。触控感应电极41为网状结构。优选的,所述网状结构为菱形。菱形的网状结构方便工作人员制备,且由于子像素11一般大小不固定,菱形的网状结构更容易正对于子像素11的间隔区域内。可选的,所述网状结构可以为正方形、矩形或不规则图形,本发明不作限制。这样通过将触控感应电极41正对于所述子像素11的间隔区域之内,可以避免触控感应电极41完全避开有机发光层14的子像素11的位置,使得子像素11发出的光完全照射,从而提高柔性显示器的发光效 果。
具体的,触控驱动电极42正对于子像素11的间隔区域之内。触控驱动电极42为网状结构。优选的,所述网状结构为菱形。菱形的网状结构方便工作人员制备,且由于子像素11一般大小不固定,菱形的网状结构容易正对于子像素11的间隔区域内。可选的,所述网状结构可以为正方形、矩形或不规则图形,本发明不作限制。这样通过将触控驱动电极42正对于所述子像素11的间隔区域之内,可以避免触控驱动电极42完全避开有机发光层14的子像素11的位置,使得子像素11发出的光完全照射,从而提高柔性显示器的发光效果。
在本实施例中,所述触控电极层40的结构为触控感应电极41与触控驱动电极42交叉绝缘设置,且当每两个触控感应电极41电连接,每两个触控驱动电极42绝缘连接时,通过导接体21将每两个触控驱动电极42电连接,且导接体21正对于子像素11的间隔区域内,这时需形成一定图案的导接体21。导接体21为金属材料或者透明导电材料形成的曲线结构。
本实施例的第一种实施方式,如图3所示,每个导接体21沿着触控感应电极41的网格路径形成多次弯折的条形导电材料。弯折的次数根据每两个触控驱动电极42之间区域存在的触控感应电极41的网格数决定。本实施方式中,每个导接体21由两条多次弯折的条形导电材料制成,两条多次弯折的条形导电材料向内弯折形成收容空间。这样可以避免当一条导接体21发生断路,另外一条导接体21可以依旧保持电连接。所述导电材料为金属材料。在其他实施方式里,每个导接体21可以由一个或者两个以上条形导电材料制成,所述导电材料也可以为有机导电材料。两条多次弯折的导接体21也可以向外弯折,本发明不作限制。所述导接体21结构路径最短,显然导接体21的电阻将最小,可以提高柔性显示器的灵敏性触控响应。
本实施例的第二种实施方式,如图4所示,每个导接体21沿着触控感应电极41的网格路径形成一次弯折的条形导电材料。本实施方式中,每个导接体21由两个一次弯折的条形导电材料制成。这样可以避免当一个条形导电材料发生断路,另外一条可以依旧保持电连接。所述导电材料为金属材料。在其他实施方式里,每个导接体21可以由一个或者两个以上条形导电材料制成, 所述导电材料也可以为有机导电材料,本发明不作限制。由于所述条形导电材料只有一次弯折,这样有利于导接体21因弯折点少,不容易发生断路。
可选的,每两个触控驱动电极42直接通过透明的有机导电材料导电连接。由于每个导接体21是透明的有机导电材料,使得子像素11发光透过导接体21,不影响柔性显示器的发光。本实施例中,每个导接体21由两条透明的有机导电材料制成。这样可以避免当一条透明的有机导电材料发生断路,另外一条透明的有机导电材料可以依旧保持电连接。在其他实施例里,每个导接体21可以由一个或者两个以上条形导电材料制成,本发明不作限制。所述导接体21工艺简单,方便工作人员制备。
如图5所示,同一行的触控感应电极41连接形成一感应电极链,同一列的所述触控驱动电极42连接形成一驱动电极链,触控感应电极链41与触控驱动电极链42交叉绝缘设置。多个所述感应电极链沿第一方向延伸且沿第二方向间隔排布,多个所述驱动电极链沿所述第二方向延伸且沿所述第一方向间隔排布。
本实施例中,同一个感应电极链上的触控感应电极41相互电连接,同一个驱动电极链的触控驱动电极42通过导接体21连接。在其他实施例里,同一个驱动电极链上的触控驱动电极42相互电连接,同一个感应电极链的触控感应电极41通过导接体21连接。
其中,“延伸”的含义是指在宽度、大小、范围上向外延长、伸展。在本实施例中是指感应电极链沿着第一方向向外伸长,驱动电极链沿着第二方向向外伸长。
如图1所示,触控电极层40上设有保护层60,所述保护层填充应力缓冲孔32。具体的,在触控电极层40的表面形成一保护层60,保护层60覆盖触控电极层40及应力缓冲孔32。保护层60用于保护柔性显示面板10避免受到水汽、氧气、灰尘及其他外界环境的影响。保护层60的材质为透明有机材料。本实施例中,所述聚合物溶液为聚酰亚胺溶液。在其他实施例中,也可以采用其他聚合物溶液,例如聚乙烯或聚对苯二甲酸乙二醇酯等。所述聚合物溶液具有高的耐受温度。聚合物溶液覆盖触控电极层40,使得触控电极层40具有柔韧性,从而实现柔性显示器的柔性触控感应。当柔性显示器发生弯折时,触控 电极层40受到的应力小,使得触控电极层40不易发生损伤或者发生断路现象。此外,聚合物溶液填充绝缘层表面的应力缓冲孔32并发生固化。由于应力缓冲孔32填充有机材料,使得柔性显示器在弯折时,柔性显示器进一步地降低所承受的应力,这样就可以进一步避免柔性显示器发生损伤或者发生断路现象。
本实施例在柔性显示面板10表面上设有一导接层20,并通过导接层20中的导接体21电连接每两个触控感应电极41或者每两个触控驱动电极42来实现柔性显示器的轻薄化及柔性触控。进一步在绝缘层30内设有应力缓冲孔32,以减小触控电极层40的拉应力或者压应力。此外,通过直接在柔性显示面板10上依次设有导接层20、绝缘层30及触控电极层40来制备柔性显示器,相较于在柔性显示面板10的表面粘贴触控层,减小了柔性显示器的制备工艺,从而降低材料及人工的成本投入。
请参阅图6,本申请还提供一种柔性显示器的制作方法,用于制备上述的柔性显示器,其包括:
步骤S10,在柔性显示面板10表面依次形成导接层20及绝缘层30,所述柔性显示面板10包括阵列排列的数个子像素11,所述导接层20包括多个间隔绝缘设置的导接体21,所述导接体21两端贯穿所述绝缘层30表面,且所述导接层20正对于所述子像素11的间隔区域内;
本实施例中,导接层20为金属材料或者透明导电材料。导接体21的材质可以为钛、铝等金属材料。本过程,导接体21为铝膜。具体的,在柔性显示面板10的表面上通过物理气相沉积方法沉积一层第一铝层,所述物理气相沉积方法为磁控溅射方法。第一铝层的表面平整均匀,粗糙度在纳米级。由于导接体21的正对于在子像素11内的间隔区域内,使得导接体21为弯折的条形状铝膜。为了形成弯折的条形铝膜。在平整的铝膜的表面上旋涂一层光刻胶,并在具有图案的掩膜板的作用下进行曝光。通过显影液将被光照射的光刻胶清洗干净,未被清洗掉的光刻胶的形状和形成弯折的条形铝膜形状一样。再利用等离子刻蚀方法在铝膜刻蚀出弯折的条形状导接体21。在其他实施例中,导接体21的材质也可以为钛/铝/钛等合金材料或者其他有机导电材料。第一铝层也可以采用热蒸镀等沉积工艺。
进一步的,利用化学气相沉积法在导接体21的表面上形成一层绝缘层30,并通过沉积与刻蚀等工艺以使所述导接体21两端贯穿所述绝缘层30表面。绝缘层30的材质可以为SiO
2、SiNx等无机材料。绝缘层30既能够保护柔性显示面板10避免受到水汽、氧气、灰尘及其他外界环境的影响,也能够避免触控电极层40的电压信号对柔性显示面板10的阵列基板层13的电学特性的影响。此外,因为触控感应电极41与触控驱动电极42为交叉绝缘设置,所以当每两个触控感应电极41电连接下通过绝缘层30及导接体21的配合能够实现每两个触控驱动电极42的电连接。当每两个触控驱动电极42电连接下通过绝缘层30及导接体21的配合能够实现每两个触控感应电极41的电连接。
步骤S20,在所述绝缘层30内形成多个应力缓冲孔32,所述子像素11正对于所述应力缓冲孔32之内;
为了在绝缘层30的表面上,产生多个应力缓冲孔32,本实施例里,在绝缘层30的表面上形成一光刻胶。将带有图案的掩膜板贴附在光刻胶的表面。再对光刻胶的表面进行曝光。利用显影液清洗去除被光源照射的光刻胶。通过等离子刻蚀法刻蚀形成多个应力缓冲孔32。所述子像素11正对于所述应力缓冲孔32之内。通过在绝缘层30的表面形成应力缓冲孔32,以当柔性显示器在发生弯折时能够有效地降低柔性显示器的应力,避免触控电极层40发生断裂而发生断路现象,也使得柔性显示器实现柔性化,避免OLED层发生损伤。
在所述步骤S20,在所述绝缘层30内形成多个应力缓冲孔32,所述子像素11正对于所述应力缓冲孔32之内。还包括:
步骤S21在所述绝缘层30内形成多个间隔设置的过孔31,所述导接体21的两端设于所述过孔31内。
具体的,所述过孔31与所述应力缓冲孔32通过刻蚀工艺同时形成。这样,不仅达到实现过孔31连接每两个触控感应电极41或者每两个触控驱动电极42的同时,还能够实现降低柔性显示器的应力,避免触控电极层40发生断裂而发生断路现象。此外,过孔31的形成不增加额外的工艺步骤。
步骤S30,在所述绝缘层30的表面形成一触控电极层40,所述触控电极层40包括多个阵列排列的触控感应电极41及多个阵列排列的触控驱动电极42,所述触控感应电极41与所述触控驱动电极42交叉绝缘设置,且每两个所 述触控驱动电极42电连接,每两个所述触控感应电极41通过所述导接体21电连接。
具体的,通过物理气相沉积法在绝缘层30的表面形成第二金属层,金属层的材质可以为钛、铝等金属材料,或者钛/铝/钛等合金材料。本实施例里,在第二金属层的表面上形成一光刻胶,将带有图案的掩膜板贴附在光刻胶的表面,并进行曝光,利用显影液清洗去除被光源照射的光刻胶。再利用等离子刻蚀法刻蚀形成触控电极层40。触控电极层40包括多个阵列排列的触控感应电极41及多个阵列排列的触控驱动电极42。触控感应电极41与触控驱动电极42交叉绝缘设置。本实施例中,所述触控电极层40的每两个触控感应电极41电连接,每两个触控驱动电极42绝缘连接。在其他实施例里,所述触控电极层40的每两个触控驱动电极42电连接,每两个触控感应电极41绝缘连接。
本实施例中在柔性显示面板10表面上形成一导接层20,并通过导接层20中的导接体21电连接每两个触控驱动电极42以制备柔性显示器。所述柔性显示器既能够实现轻薄化及柔性触控,也可以实现减小了柔性显示器的制备工艺,从而降低材料及人工的成本投入。进一步在绝缘层30内形成应力缓冲孔32,以减小触控电极层40的拉应力或者压应力。
以上所揭露的仅为本发明较佳实施例而已,当然不能以此来限定本发明之权利范围,本领域普通技术人员可以理解实现上述实施例的全部或部分流程,并依本发明权利要求所作的等同变化,仍属于发明所涵盖的范围。
