请参阅图2C,所述第一粘结层30的面积与所述第二粘结层40的面积相等。请参阅图3C,所述第一粘结层30的面积小于所述第二粘结层40的面积。
S50、在所述第一显示面板10或所述第二显示面板20远离所述第一粘结层30一侧形成盖板层50;
在本步骤中,主要利用所述第二贴合机台在所述第一显示面板10或所述第二显示面板20远离所述第一粘结层30一侧形成所述盖板层50。
请参阅图2D,所述盖板层50形成于所述第一封装层104上。
请参阅图3D,所述盖板层50形成于所述第二封装层204上。
S60、利用紫外光对所述显示模组进行固化工艺。
在本步骤中,由于所述第一粘结层30及所述第二粘结层40为光学胶。光学胶经紫外光照射固化,使得所述第一显示面板10与所述第二显示面板20之间粘结的更可靠。
本申请通过在将两个OLED显示面板叠加设置,并通过控制两个显示面板的贴合间距以实现3D显示,使得用户无须佩戴3D眼镜,降低了工艺难度,节省了成本,提升了用户体验;去除了背光单元,降低了产品的厚度。
请参阅图4,图4为本申请显示模组的膜层结构图。
所述显示模组100包括:
第一显示面板10。在一种实施例中,所述第一显示面板10为有机发光二极管显示面板。
所述第一显示面板10包括第一衬底101、位于所述第一衬底101上的第一薄膜晶体管层102、位于所述第一薄膜晶体管层102上的第一发光器件层103、位于所述第一发光器件层103上的第一封装层104。
在一种实施例中,所述第一衬底101可以为柔性基板。所述柔性基板的材料可以为PI(聚酰亚胺)。
位于所述第一显示面板10上的第二显示面板20。
在一种实施例中,所述第二显示面板20为有机发光二极管显示面板。
在一种实施例中,所述第二显示面板20包括第二衬底201、位于所述第二衬底201上的第二薄膜晶体管层202、位于所述第二薄膜晶体管层202上的第二发光器件层203、位于所述第二发光器件层203上的第二封装层204。
在一种实施例中,所述第二衬底201为柔性基板。所述柔性基板的材料可以为PI(聚酰亚胺)。
位于所述第二显示面板20上的盖板层50。
请参阅图4,所述显示模组100还包括位于所述第一显示面板10远离所述第二显示面板20一侧的第一粘结层30、及所述第一显示面板10与所述第二显示面板20之间的第二粘结层40。
在一种实施例中,所述第一粘结层30及所述第二粘结层40的材料为光学胶。
所述第一粘结层30及所述第二粘结层40通过第一贴合机台贴合于所述第一显示面板10或所述第二显示面板20上。所述第二显示面板20与所述第一显示面板10之间通过第二贴合机台进行对应贴合工艺。
在形成所述第一粘结层30及所述第二粘结层40时,面板易出现气泡等凸起物。该凸起物易导致面板的划伤或面板显示不良。因此,在形成所述第一粘结层30及所述第二粘结层40之后,还需要对形成有所述第一粘结层30或所述第二粘结层40的显示面板进行脱泡工艺。通过第一贴合机台将贴合过程中产生的气泡打散以减小内应力。
在一种实施例中,根据显示面板贴合顺序的不同,所述第一显示面板10及所述第二显示面板20的大小也不同。请参阅图4,本实施例中,所述第一显示面板10位于所述第二显示面板20上,所述第一显示面板10的面积小于所述第二显示面板20的面积。
在一种实施例中,所述第二显示面板20的各边界长度较所述第一显示面板10的对应的各边界长度大0.1mm。所述第一显示面板10与所述第二显示面板20的贴合精度为0.1±0.05mm。
根据本申请的一个方面,本申请还提供了一种电子装置,所述电子装置包括所述显示模组100。所述电子装置包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
所述电子装置的工作原理与所述显示模组100的工作原理相似,所述电子装置的工作原理具体可以参考所述模组的工作原理,这里不做赘述。
本申请提供一种显示模组及其制作方法、电子装置,包括:提供第一显示面板;在所述第一显示面板的一侧形成第一粘结层;提供第二显示面板,将所述第二显示面板贴合于形成有所述第一粘结层的所述第一显示面板一侧;在远离所述第一粘结层的所述第一显示面板或所述第二显示面板的一侧形成第二粘结层;在所述第一显示面板或所述第二显示面板远离所述第一粘结层一侧形成盖板层。本申请通过在将两个OLED显示面板叠加设置,并通过控制两个显示面板的贴合间距以实现3D显示,使得用户无须佩戴3D眼镜,降低了工艺难度,节省了成本,提升了用户体验;去除了背光单元,降低了产品的厚度。
综上所述,虽然本申请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申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
