以下各实施例的说明是参考附加的图示,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。在图中,结构相似的单元是用以相同标号表示。
本发明针对现有的柔性显示器中,弯折工序后两段背板易发生错位,从而导致弯折圆弧形状不佳,降低产品品质的技术问题。本发明可以解决上述问题。
一种柔性显示器,如图2所示,所述柔性显示器包括柔性面板20、设置于所述柔性面板20下侧上的背板30、设置在所述柔性面板20上侧上的封装层40、设置于所述封装层40上的触控层50、设置于所述触控层50上的偏光片60,以及,设置于所述偏光片60上的封装盖板层70。
其中,所述柔性面板20具有显示部21、绑定部23以及位于所述显示部21与所述绑定部23之间的弯折部22;进行弯折制程时,将所述柔性面板20上的绑定部23沿所述弯折部22弯折至所述背板30的背侧并将所述绑定部23与所述背板30连接。
其中,所述绑定部23沿所述弯折部22弯折至所述背板30的背侧时通过一粘结层80与所述背板30连接,所述粘结层80包括至少三层层叠设置的胶层。
参见图3和图4,将绑定部23弯折至所述背板30的背侧后,利用多层层叠设置的胶层形成的粘结层80粘结所述背板30和所述绑定部23,即使绑定部23与背板30的连接位置不准确导致弯折部22形成的弯折圆弧形状不佳(如图3),此时粘结层80中位于中间的胶层尚未固化,粘结层80中位于上层和下层的胶层受力可错位,从而可对绑定部23的位置进行移动调整进行错位补偿,从而使弯折圆弧形状良好(如图4),提高产品品质。
在一实施方式中,所述显示面板处于未弯折状态时,所述粘结层80设置于所述背板30上。
具体的,所述粘结层80包括层叠设置的第一胶层81、第二胶层82以及第三胶层83,所述第二胶层82为热敏胶胶层或光敏胶胶层。
对于本领域技术人员可知,由热敏胶形成的热敏胶胶层在常温下流动性好,加热后固化;由光敏胶形成的光敏胶胶层在常温且未经紫外光照射的情况下流动性好,经紫外光照射后固化,利用热敏胶或光敏胶形成第二胶层82,便于绑定部23与背板30连接时对绑定部23的位置进行移动调整以使弯折圆弧形状良好。
其中,所述第二胶层82包括相对设置的第一载体821和第二载体822以及位于所述第一载体821与所述第二载体822之间的热敏胶或光敏胶,所述第一载体821设置于所述第一胶层81上,所述第二载体822设置于所述第三胶层83上。
在一实施方式中,所述第一胶层81和所述第三胶层83均为压敏胶胶层,所述绑定部23通过粘结层80与所述背板30连接时,所述第一胶层81与所述绑定部23粘结。
需要说明的是,对于本领域技术人员可知,由压敏胶制备的压敏胶胶层在常温且受到的压力较小的情况下流动性较好,从而便于将第一胶层81与绑定部23粘结,而当压敏胶胶层受到较大压力时,压敏胶胶层的粘性强,从而防止绑定部23与背板30脱落。
需要说明的是,实际实施中,所述第一胶层81和所述第三胶层83的制备材料也可以与所述第二胶层82相同。
具体的,所述封装层40与所述触控层50之间设置有第一光学胶层102,所述触控层50通过第一光学胶层102与所述封装层40连接固定。
具体的,所述偏光片60与所述封装盖板层70之间设置有第二光学胶层103,所述封装盖板层70通过第二光学胶层103与所述偏光片60连接固定。
具体的,所述触控层50通过一柔性电路板104与所述柔性面板20电性连接,所述柔性电路板104的部分弯折至所述背板30的背侧并与所述绑定部23电性连接。
具体的,所述背板30的背侧上还固定设置有保护层90。
具体的,所述柔性面板20上设置有覆盖所述弯折部22的加强层101,所述加强层101为柔性胶层。
利用加强层101提高弯折部22的可弯折强度,防止弯折过程中弯折部22处产生裂纹。
在一实施方式中,所述加强层101的制备材料为光敏胶。
如图5所示,在另一实施方式中,所述柔性面板20处于未弯折状态时,所述粘结层80设置于所述绑定部23上。
本发明的有益效果为:将绑定部23弯折至所述背板30的背侧后,利用多层层叠设置的胶层形成的粘结层80粘结所述背板30和所述绑定部23,同时粘结层80中的第二胶层82在自然环境中处于未固化状态,具有较好的流动性,即使绑定部23与背板30的连接位置不准确导致弯折圆弧形状不佳,此时粘结层80中位于上层和下层的第一胶层81和第三胶层83受力可错位,从而可对绑定部23的位置进行移动调整进行错位补偿,从而使弯折圆弧形状良好,提高产品品质。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
