为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:
图1为本发明实施例提供的盖板的结构示意图。
图2为本发明实施例提供的基板和盖板组装成显示屏的场景示意图。
图3为本发明实施例提供的盖板的制作方法的流程示意图。
以下各实施例的说明是参考附加的图式,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,结构相似的单元是以相同标号表示。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本发明实施例提供了一种显示屏,该显示屏包括盖板和基板,二者相对设置,形成收纳空间,用于收纳基板上的组件。
基板可以为刚性基板,也可以为刚性基板。基板上设置了薄膜晶体管层、电致发光器件层等结构。
请参照图1,图1为本发明实施例提供的盖板的结构示意图。该盖板1包括玻璃盖板11、封装层12以及缓冲层13。
如图1所示,玻璃盖板11包括挖孔区域111。挖孔区域111下方对应设置有光线传感器、摄像头等组件。
封装层12的组成材料包括玻璃胶。封装层12设置在玻璃盖板11的一侧,具体的,当组装盖板1和基板时,封装层12设置在玻璃盖板11和基板之间,用于保护位于玻璃盖板11和基板收纳空间的组件,防止被外界水氧侵蚀。
如图1所示,封装层12可以包括第一封装层121和第二封装层122。其中,第一封装层121环绕挖孔区域111设置,第二封装层122环绕玻璃盖板11边缘设置。第一封装层121和第二封装层122的高度和宽度可以相同,也可以不相同。具体的,第一封装层121和第二封装层122的高度范围在5-6微米之间。第一封装层121和第二封装层122的宽度范围在300-400微米之间。
缓冲层13设置在玻璃盖板11远离封装层12的一侧,并且缓冲层13设置在玻璃盖板11上的挖孔区域111上。该缓冲层13用于在挖孔区域111挖孔时,对封装层12产生的应力进行缓冲。
其中,缓冲层13可以完全覆盖该挖孔区域111,也可以部分覆盖该挖孔区域。在一实施例中,当挖孔区域111的孔径范围较大时,如果缓冲层13全部覆盖挖孔区域111,需要较多的缓冲材料,故可以使缓冲层13部分覆盖该挖孔区域111,以节省资源。比如,当盖板1应用在智能手机中时,挖孔区域的孔径范围比较大,大致在3-4毫米之间,此时,可以使缓冲层13部分覆盖挖孔区域111。在一实施例中,当盖板1应用在精密照相机等精密仪器中时,此时挖孔区域111的孔径范围比较小,大致在0.5-1.5毫米之间,此时,可以使缓冲层13全部覆盖挖孔区域111,以使缓冲层13具有足够大的缓冲面积,提高缓冲效果。
在一实施例中,缓冲层13的高度大于或等于第一封装层121的高度。这样,当对挖孔区域111进行挖孔时,缓冲层13可以为位于挖孔区域111下方的第一封装层12分担足够多的应力。
在一实施例中,缓冲层13的组成材料包括胶材。该胶材可以为高分子类胶材或光敏胶。具体的,高分子类胶材包括乙基纤维素、羟乙基纤维素、醋酸纤维素以及醋酸丁酸纤维素中的一种或多种。其中,高分子类胶材分子量大,可以提供更大的缓冲力。进一步的,可以根据不同的缓冲力需求,选择不同分子量大小的胶材,形成该缓冲层13。
需要说明的是,由于胶材具有流动性和粘接性,因此当对挖孔区域111进行钻孔后,缓冲层13中的胶材流入形成的通孔中,在第一封装层121内侧形成一以胶材为组成材料的保护层,可以防止外界水氧的侵蚀。
在一实施例中,缓冲层13还可以由其他具有缓冲性质的材料组成。具体的,缓冲层13的组成材料包括环氧丙烯酸酯、聚醚酰亚胺、聚甲基丙烯酸甲酯、聚对苯二甲酸乙二醇酯、聚氨酯丙烯酸酯、聚醚丙烯酸酯、聚酯丙烯酸酯、丙烯酸树脂、聚丙烯酸、聚丙烯酸钠、聚乙烯亚胺、聚乙烯醇、聚四氢呋喃、聚(1,4-丁二醇丁二酸)酯或聚乙烯吡咯烷酮中的一种或多种。
在一实施例中,为了提高基板2和封装层12之间的粘接性能,还可以在基板2与封装层12的相对位置上设置一固定层。其中,固定层的组成材料包括氮化硅或氧化硅。该固定层设置为镂空状,以提高基板2和封装层12之间的粘接力。
请参照图2,图2为本发明实施例提供的盖板和基板组装成显示屏的场景示意图。以下结合图2,对盖板和基板的组装过程进行详细介绍。
首先,提供一玻璃盖板11,该玻璃盖板11包括挖孔区域111。在玻璃盖板11的一侧形成封装层12。具体的,封装层12可以包括第一封装层121和第二封装层122。其中,第一封装层121环绕挖孔区域111设置,第二封装层122环绕玻璃盖板11边缘设置。再在玻璃盖板11远离封装层12的一侧形成缓冲层13,并且缓冲层13设置在玻璃盖板11上的挖孔区域111上。
提供一基板2,该基板2上包括薄膜晶体管层、电致发光器件层等结构。
然后,将盖板1和基板2对齐贴合,再用激光使第一封装层121和第二封装层122中的玻璃胶融化,使盖板1和基板2粘接在一起。
最后,对玻璃盖板11上的挖孔区域111进行钻孔,此时缓冲层13起到缓冲作用,缓解钻孔产生的应力对封装层12的影响。
需要说明的是,当缓冲层13的组成材料为胶材时,由于胶材具有流动性和粘接性,因此对挖孔区域111进行钻孔后,缓冲层13中的胶材流入形成的通孔a中,在第一封装层121内侧形成一以胶材为组成材料的保护层14,可以防止外界水氧的侵蚀。
本发明实施例还提供了一种盖板的制作方法。请参照图3,图3为本发明实施例提供的盖板的制作方法的流程示意图。该盖板的制作方法包括:

步骤S102,在玻璃盖板的一侧,形成封装层。
封装层12的组成材料包括玻璃胶。封装层12设置在玻璃盖板11的一侧,具体的,当组装盖板1和基板时,封装层12设置在玻璃盖板11和基板之间,用于保护位于玻璃盖板11和基板收纳空间的组件,防止被外界水氧侵蚀。
如图1所示,封装层12可以包括第一封装层121和第二封装层122。其中,第一封装层121环绕挖孔区域111设置,第二封装层122环绕玻璃盖板11边缘设置。第一封装层121和第二封装层122的高度和宽度可以相同,也可以不相同。具体的,第一封装层121和第二封装层122的高度范围在5-6微米之间。第一封装层121和第二封装层122的宽度范围在300-400微米之间。
步骤S103,在玻璃盖板远离封装层的一侧,形成缓冲层,并使缓冲层设置在玻璃盖板上的挖孔区域上,缓冲层用于对所挖孔区域挖孔时产生的应力进行缓冲。
在一实施例中,可以采用点胶或者丝网印刷的方式形成缓冲层。具体的,当挖孔区域111的面积较大时,比如挖孔区域111的孔径在3-4毫米之间时,可以采用点胶的方式。当挖孔区域111的面积较小时,比如挖孔区域111的孔径在0.5-1.5毫米之间时,可以采用丝网印刷的方式。
缓冲层13设置在玻璃盖板11远离封装层12的一侧,并且缓冲层13设置在玻璃盖板11上的挖孔区域111上。该缓冲层13用于在挖孔区域111挖孔时,对封装层12产生的应力进行缓冲。
其中,缓冲层13可以完全覆盖该挖孔区域111,也可以部分覆盖该挖孔区域。在一实施例中,当挖孔区域111的孔径范围较大时,如果缓冲层13全部覆盖挖孔区域111,需要较多的缓冲材料,故可以使缓冲层13部分覆盖该挖孔区域111,以节省资源。比如,当盖板1应用在智能手机中时,挖孔区域的孔径范围比较大,大致在3-4毫米之间,此时,可以使缓冲层13部分覆盖挖孔区域111。在一实施例中,当盖板1应用在精密照相机等精密仪器中时,此时挖孔区域111的孔径范围比较小,大致在0.5-1.5毫米之间,此时,可以使缓冲层13全部覆盖挖孔区域111,以使缓冲层13具有足够大的缓冲面积,提高缓冲效果。
在一实施例中,缓冲层13的高度大于或等于第一封装层121的高度。这样,当对挖孔区域111进行挖孔时,缓冲层13可以为位于挖孔区域111下方的第一封装层12分担足够多的应力。
在一实施例中,缓冲层13的组成材料包括胶材。该胶材可以为高分子类胶材或光敏胶。具体的,高分子类胶材包括乙基纤维素、羟乙基纤维素、醋酸纤维素以及醋酸丁酸纤维素中的一种或多种。其中,高分子类胶材分子量大,可以提供更大的缓冲力。进一步的,可以根据不同的缓冲力需求,选择不同分子量大小的胶材,形成该缓冲层13。
需要说明的是,由于胶材具有流动性和粘接性,因此当对挖孔区域111进行钻孔后,缓冲层13中的胶材流入形成的通孔a中,在第一封装层121内侧形成一以胶材为组成材料的保护层14,可以防止外界水氧的侵蚀。
本发明实施例的盖板、显示屏以及盖板的制作方法,通过在玻璃盖板挖孔区域上设置缓冲层,降低了在挖孔区域挖孔时,对封装层的应力,提高了盖板的良率。
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。
