具体实施方式
下面将结合本申请中的附图,对本申请中的技术方案进行清楚且完整地描述。在对本申请的实施例进行描述之前,首先对“可折弯”进行解释。所谓的“可折弯”是指在外力的作用下能够被折弯,并且在该外力被撤销后,还能够恢复原状。
可折弯盖板
参见附图1,它示出了本申请提供的一种可折弯盖板的结构示意图。应当知道的是,该可折弯盖板是透明的。需要说明的是,该可折弯盖板通常用在终端设备上,用于覆盖该终端设备的显示屏。该终端设备具体可以为智能手机、平板电脑(PAD)或其他具有显 示屏的电子产品。
具体的,该可折弯盖板包括第一硬质板101、第二硬质板102和柔性基板200。其中,该柔性基板200的上表面包括第一硬质区201、第二硬质区203和第一折弯区202,该第一折弯区202位于所述第一硬质区201和所述第二硬质区203之间,且所述第一硬质区201和所述第二硬质区203均与所述第一折弯区202相邻。需要说明的是,所述第一硬质板101通过第一透明粘结层103粘结在所述第一硬质区201,所述第二硬质板102通过第二透明粘结层104粘结在所述第二硬质区203。
可选的,沿着所述第一硬质板101的厚度方向,所述第一硬质板101在所述第一硬质区201所在平面上的投影和所述第一硬质区201完全重合。
可选的,沿着所述第二硬质板102的厚度方向,所述第二硬质板102在所述第二硬质区203所在平面上的投影和所述第二硬质区203完全重合。
从另一个维度来说,本申请提供的可折弯盖板包括第一硬质部,第二硬质部和第一折弯部。其中,该第一硬质部和该第二硬质部均呈平板状。如图1、图2A和2B所示,该第一硬质部包括该第一硬质区对应的柔性基板211、该第一硬质板101和该第一透明粘结层103。该第二硬质部包括该第二硬质区对应的柔性基板213、该第二硬质板102和该第二透明粘结层104。该第一折弯部是指该第一折弯区对应的柔性基板212。
值得注意的是,参见图2B可知,前文提及的“该第一硬质区对应的柔性基板211”、“该第二硬质区对应的柔性基板213”以及“该第一折弯区对应的柔性基板212”分别是该柔性基板200的一部分。其中,该第一硬质区对应的柔性基板211、该第二硬质区对应的柔性基板213以及该第一折弯区对应的柔性基板212均可以是沿所述柔性基板200的厚度方向对所述柔性基板200进行切割得到的,其中,该切割是沿该柔性基板200的厚度方向贯穿该柔性基板200的。在该柔性基板200仅仅包括该第一硬质区对应的柔性基板211、该第二硬质区对应的柔性基板213以及该第一折弯区对应的柔性基板212的情况下,则应当理解,该第一硬质区对应的柔性基板211、该第二硬质区对应的柔性基板213以及该第一折弯区对应的柔性基板212能够拼接成该柔性基板200。需要说明的是,该拼接完成后(或者说在拼接得到该柔性基板后),该第一硬质区201、该第二硬质区203和该第一折弯区202均位于同一平面。其中,该平面也为该柔性基板200的上表面所在的平面。进一步地,该第一硬质区对应的柔性基板211的上表面为该第一硬质区201,该第二硬质区对应的柔性基板213的上表面为该第二硬质区203,该第一折弯区对应的柔性基板212的上表面为该第一折弯区202。
需要说明的是,本申请中所述的折弯区是指可以被折弯的区域,或者说是柔性区域。所谓“可以被折弯的区域”具体是指在外力的作用下能够被折弯,且在该外力被撤销后,能够恢复原状的区域。相应地,本申请中所述的硬质区是指不能够被折弯的区域,也即在外力的作用下被折弯后,会发生应力开裂,且在该外力被撤销后,不能够恢复原状的区域。应当知道的是,从微观上来说,在施加的外力足够小的情况下,所有的物质都能够发生形变,因此,绝对的不能被折弯的物体严格上来说是不存在的。因此,对于本申请中提及的折弯区和硬质区,应当从本领域技术人员的视角进行理解。
值得注意的是,本申请中所述的“第一”、“第二”或“第三”等,仅用于相互区分。比如第一硬质区和第二硬质区,该第一和该第二是为了说明这两个硬质区不是同一 个硬质区。类似地,第一透明粘结层和第二透明粘结层中的第一和第二也是为了说明这两个透明粘结层不是同一个透明粘结层。
应当知道的是,本申请所述的第一折弯区可以参见前述对折弯区的解释。本申请所述的第一硬质区和第二硬质区可以参见前述对硬质区的解释。因此将不再重复解释。
进一步地,在本申请中,如图3A和3B所示,在该第一折弯部302被折弯的情况下,该第一硬质部的内表面3011所在的平面和该第二硬质部的内表面3031所在的平面之间的最小夹角大于或等于0度且小于180度。
应当知道的是,两条直线相交后会形成两对对顶角,假设第一对对顶角的大小为a,第二对对顶角的大小为b,其中,a小于b,则a为这两条直线的最小夹角。由于两个相交的平面的截面可以视为两条相交的直线,因此a也为该两个相交的平面之间的最小夹角。需要说明的是,此处关于最小夹角的定义适用于本申请任意一处出现的最小夹角,因此后续再出现最小夹角时,将不会再重复定义。
具体的,如图3A和3B所示,在该第一折弯部302被折弯时,该第一硬质部301和该第二硬质部303相互靠近,则该第一硬质部的内表面3011是朝向该第二硬质部的内表面3031的。所谓的“该第一硬质部的内表面3011朝向该第二硬质部的内表面3031”,可以理解为:该第一硬质部的内表面3011在第一平面上具有分量,该第一平面平行于该第二硬质部的内表面3031。
需要说明的是,本申请提供的该可折弯盖板能够双向折弯。应当知道的是,该双向折弯中的任一种折弯均是将该可折弯盖板沿垂直于位于该可折弯盖板内的柔性基板的表面的直线进行折弯的。
值得注意的是,在该第一折弯部302被折弯的情况下,该可折弯盖板形成一个“U”型或类似“U”型的结构,则该“U”型或类似“U”型结构的开口朝向为该可折弯盖板的折弯方向。具体的,可以把包括该第一硬质部301、该第一折弯部302和该第二硬质部303的结构称为第一结构,则在该第一折弯部302被折弯的情况下,该第一结构为一个“U”型或类似“U”型的结构,相应地,该“U”型或类似“U”型结构的开口朝向即为该第一结构的折弯方向。
可选的,本申请所述的硬质板可以为2.5维硬质玻璃(后续简称“2.5D硬质玻璃”)或3维硬质玻璃(后续简称“3D硬质玻璃”)。应当知道的是,本申请所述的硬质板可以为所述第一硬质板或所述第二硬质板。进一步地,该硬质板还可以为本申请其他实施例中出现的第三硬质板。
可选的,本申请所述的第一硬质板和第二硬质板所使用的材料均是高硬度的透光材料。具体的,该高硬度的透光材料可以为玻璃(可选的,为强化玻璃或蓝宝石)或聚甲基丙烯酸甲酯(Polymethyl Methacrylate,PMMA)等。值得注意的是,该高硬度的透光材料的硬度大于或等于8H,其中,H为铅笔硬度。
进一步可选的,该第一硬质板所使用的材料和该第二硬质板所使用的材料是相同的。
进一步可选的,该第一硬质板的硬度和该第二硬质板的硬度是相同的。
可选的,本申请所述的硬质板的厚度大于或等于0.3毫米且小于或等于0.8毫米。类似地,本申请所述的该硬质板可以为所述第一硬质板或所述第二硬质板。进一步地,该 硬质板还可以为本申请其他实施例中出现的第三硬质板。
进一步可选的,所述第一硬质板的厚度和所述第二硬质板的厚度是相等的。
需要说明的是,本申请所述的第一透明粘结层和第二透明粘结层均是透明且具有粘性的。具体的,该第一透明粘结层所使用的材料可以为OCA或UV胶等,相应的,该第二透明粘结层所使用的材料可以为OCA或UV胶等。可选的,该第一透明粘结层所使用的材料和该第二透明粘结层所使用的材料是相同的。
可选的,该第一透明粘结层的厚度和该第二透明粘结层的厚度是相同的。
可选的,该第一透明粘结层的透光率和该第二透明粘结层的透光率均大于或等于91%。进一步可选的,该第一透明粘结层的透光率和该第二透明粘结层的透光率是相等的。
值得注意的是,在本申请中,所述柔性基板的折弯区能够被折弯,所述柔性基板的硬质区不能够被折弯。所以,在所述柔性基板的折弯区被折弯的情况下,所述柔性基板的硬质区依然保持平整。所述折弯区可以为所述第一折弯区,也可以为后续其他实施例所述的第二折弯区。所述硬质区可以为所述第一硬质区或所述第二硬质区,可以为后续其他实施例所述的第二硬质区。
需要说明的是,在本申请中,该柔性基板所使用的材料可以为玻璃,也可以为塑料。在该柔性基板所使用的材料为玻璃时,该柔性基板具体为玻璃薄膜。在该柔性基板所使用的材料为塑料时,该柔性基板具体为塑料薄膜。在该柔性基板为塑料薄膜的时候,则该柔性基板可以为聚酰亚胺(Polyimide,PI)薄膜、聚对苯二甲酸乙二醇酯(Polyethylene Terephthalate,PET)薄膜、聚碳酸酯(Polycarbonate,PC)薄膜、聚萘二甲酸乙二醇酯(Polyethylene Naphthalate,PEN)薄膜或者聚甲基丙烯酸甲酯(Polymethyl Methacrylate,PMMA)薄膜。

可选的,该柔性基板的硬度大于或等于8H。
可选的,所述柔性基板的厚度是均匀的。换句话说,也即所述柔性基板的上表面是平行于所述柔性基板的下表面的。
值得注意的是,本申请所述的柔性基板所使用的材料是透光的。可选的,该柔性基板的透光率大于或等于91%.
在本申请的一个实施例中,如图3A所示,并结合图1,在该第一折弯部302被折弯的情况下,该第一硬质部的内表面3011为所述第一硬质板101的上表面,所述第一硬质板101的上表面与所述第一硬质板101的下表面是相背离的,其中,所述第一硬质板101的下表面通过所述第一透明粘结层103与所述第一硬质区201相粘结。类似地,所述第二硬质部的内表面3031为所述第二硬质板102的上表面,所述第二硬质板102的上表面与所述第二硬质板102的下表面是相背离的,所述第二硬质板102的下表面通过所述第二透明粘结层104与所述第二硬质区203相粘结。需要说明的是,为了表述方便,后续将本实施例所述的折弯称为正向折弯。
前文提到该第一折弯部被折弯后,该第一结构为一个“U”型或类似“U”型的结构。具体的,在该第一折弯部被正向折弯后,该第一硬质部的内表面3011和该第二硬质部的内表面3031均为该“U”型或类似“U”型结构的内表面的一部分。还应当知道的 是,在该第一折弯部被正向折弯后,该第一硬质板101和该第二硬质板102均位于该“U”型或类似“U”型结构的内部。
可选的,在本实施例中,该第一折弯部302的最小曲率半径的选取受该第一硬质板101的厚度以及该第二硬质板102的厚度限制。具体的,在该第一折弯部302被正向折弯的情况下,该第一折弯部302的最小曲率半径能够满足该第一硬质部的内表面3011和该第二硬质部的内表面3031相贴合。
在本申请的另一个实施例中,如图3B所示,并结合图1和图2B,在该第一折弯部302被折弯的情况下,该第一硬质部的内表面3011为所述第一硬质区对应的柔性基板211的下表面,其中,所述第一硬质区对应的柔性基板211的下表面和所述第一硬质区201是相背离。类似地,该第二硬质部的内表面3031为所述第二硬质区对应的柔性基板213的下表面,所述第二硬质区对应的柔性基板213的下表面和所述第二硬质区203也是相背离的。为了表述方便,后续将本实施例所述的折弯称为反向折弯。
前文提到该第一折弯部302被折弯后,该第一结构为一个“U”型或类似“U”型的结构。类似的,在该第一折弯部302被反向折弯后,该第一硬质部的内表面3011和该第二硬质部的内表面3031均为该“U”型或类似“U”型结构的内表面的一部分。还应当知道的是,在该第一折弯部302被反向折弯后,该第一硬质板101和该第二硬质板102均位于该“U”型或类似“U”型结构的外部。

值得注意的是,通常,该第一折弯部302在正向折弯时的曲率半径是不同于该第一折弯部302被反向折弯时的曲率半径的。
作为本申请的一个实施例,如图2A所示,该第一折弯区202的宽度大于或等于πR,其中R为所述第一折弯区202的最小曲率半径。应当知道的是,曲率半径是曲率的倒数,该第一折弯区202的曲率越大,表示该第一折弯区202能够弯曲的程度越大。
如图2A所示,前文提及该第一硬质区201和该第二硬质区203均和该第一折弯区202相邻。具体的,在本实施例中,该第一硬质区201与该第一折弯区202之间的分界线为一条直线,该第二硬质区203和该第一折弯区202之间的分界线也为一条直线,并且这两条分界线是相互平行的。应当知道的值,这两条分界线之间的距离就是该第一折弯区202的宽度。
应当知道的是,在本申请中,该第一硬质区201和该第二硬质区203被该第一折弯区202所隔离。所谓的隔离,是指该第一硬质区201和该第二硬质区203之间不存在重叠相互的区域。对于后续出现的“隔离”,均请参见此处的解释。
可选的,在本实施例中,该第一折弯区202的宽度是毫米级的。进一步可选的,该第一折弯区202的曲率半径大于或等于4.7毫米。
作为本申请的再一个实施例,如图2A所示,该第一硬质区201的边可以分为内边2011和外边2012两部分,则该第一硬质区的内边2011是指该第一硬质区201与该第一折弯区202的分界线,相应地,该第一硬质区201的边中除了该内边2011之外的其他边为该第一硬质区的外边2012。参见附图2A,容易看出,该第一硬质区的外边2012与该柔 性基板200的上表面的部分边相重合。

需要说明的是,在本实施例中,由于该壳体支撑件101位于被折弯的该可折弯终端设备的内侧,因此该可折弯显示模组102的曲率半径受限于该壳体支撑件101的厚度。
作为本申请的另一实施例,如图11所示,在该可折弯终端设备被折弯的情况下,该壳体支撑件101位于被折弯的该可折弯终端设备的外侧,所述可折弯显示模组102位于被折弯的所述可折弯终端设备的内侧。
需要说明的是,在本实施例中,受限于该可折弯显示模组102的最小曲率半径,该可折弯显示模组102通常仅能被折弯30度。
值得注意的是,上述多个实施例之间可以相互参见,比如关于第四胶体的限定可以参见关于第一胶体的限定,此处不再赘述。
应当知道的是,前述实施例仅为本发明的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应该以权利要求的保护范围为准。
