全面屏窄边框设计成为手机、平板电脑等大部分电子设备的一种发展趋势,窄边框屏幕可以为用户提供极致的视觉效果,同时在相同的产品尺寸上能够实现更大的可显示区域。
相关技术中的显示屏已可做到左右上三边框区域的窄边框,但是,对于下边框区域(俗称下巴)的窄边框设计仍然存在不少技术难点。
显示模组是显示屏的核心组件,相关技术中为确保显示屏的显示效果,通常在显示模组的显示部分以外的预定区域(对应于显示屏的下边框区域)上设置一个芯片封装区域或者屏幕排线绑定区域,以此实现芯片固定或排线固定,而这也导致了难以进一步实现显示屏的下边框区域的窄边框设计,尤其是如有源矩阵有机发光二极体(Active-matrix organic light emitting diode,AMOLED)和薄膜场效应晶体管(Thin Film Transistor,TFT)结构等以玻璃为基材的显示屏的下边框区域的窄边框设计。

提供一第一目标基板以及一第二目标基板;

将一柔性电路板与第三表面贴合连接,并与线路连接部电连接,得到显示模组。
本公开实施例中,通过将柔性电路板贴合连接于第一基板的第三表面并通过线路层延伸至第三表面的线路连接部实现电连接,从而能够避免该柔性电路板占用第一基板的第一表面的面积,进而减小显示模组的下边框区域尺寸,实现下窄边框设计。

此外,本公开实施例中,该显示模组还可以包括诸如用于起保护作用的缓冲结构、透明盖板以及用于容置各个部件的壳体等等一系列基本部件,本公开实施例中对此不再一一赘述。
本公开实施例提供的显示模组,通过将柔性电路板贴合连接于第一基板的第三表面并通过线路层延伸至第三表面的线路连接部实现电连接,从而能够避免该柔性电路板占用第一基板的第一表面的面积,进而减小显示模组的下边框区域尺寸,实现下窄边框设计。
另外,本公开实施例还提供一种电子设备,可以包括上述的显示模组。
本公开实施例中,由于在相关技术中提供了电子设备本体的结构,显示 模组的结构原理在上述实施例中已进行详细说明,因此,本实施例中对于具体的电子设备的结构不再赘述。
其中,本公开实施例中,该电子设备可以为手机或平板电脑。当然,该设备并不局限于手机和平板电脑,其也可以为膝上型电脑(Laptop Computer)或个人数字助理(Personal Digital Assistant,PDA)等等电子设备。
本公开实施例中,具备上述显示模组的电子设备,由于显示模组能够避免该柔性电路板占用第一基板的第一表面的面积,减小显示模组的下边框区域尺寸,因此能够进一步实现电子设备的下窄边框设计。
此外,请参见图6,其示出的是本公开实施例提供的显示模组的制造方法的流程示意图,本公开实施例还提供一种显示模组的制造方法,可以包括以下步骤:
步骤601,提供一第一目标基板以及一第二目标基板。
步骤602,在第一目标基板上开设一凹槽。
本步骤中,如图7所示,标号11为第一目标基板,标号13为凹槽,通过在第一目标基板11上的预定位置区域开设凹槽13,这里,凹槽13上与第一目标基板11连接的其中一侧面(第一侧面)将成为第一基板的第三表面的一部分。其中,凹槽的底面与第一目标基板的预设表面之间的距离(即凹槽的侧面高度尺寸)以及该凹槽的侧面宽度尺寸可以根据实际设计需求进行设置,该凹槽的侧面高度尺寸一般可以根据显示模组的第一基板厚度以及柔性电路板的电连接的接触面积等进行设置,该凹槽的侧面宽度尺寸可以根据显示模组的第一基板宽度进行设置。
步骤603,在凹槽的第一侧面以及第一目标基板的预设表面上进行金属线路镀膜,形成线路层,其中,凹槽的第一侧面与第一目标基板的预设表面相接,线路层位于第一侧面的部分形成为线路连接部。
本步骤中,如图8所示,凹槽的第一侧面为凹槽与第一目标基板的预设表面相接的一个侧面,通过在第一目标基板11的预设表面和凹槽13的第一侧面上进行线路镀膜,以形成用于实现显示模组的显示驱动的线路层111,其中,线路层111位于第一侧面的部分形成为与柔性电路板电连接的线路连接部。
本公开实施例中,该线路层具体可以为金属线路层,可以通过真空溅镀等镀膜方式将线路层镀到第一目标基板的预设表面和凹槽的第一侧面,具体地,在镀膜完成后,可以通过曝光蚀刻脱膜得到线路图案,此时,线路连接部包括至少一个第一连接引脚。另外,本公开实施例中,可选地,线路层可以为单层金属材质制成,例如,该线路层可以为Mo、Al以及Ti等中的其中一种制成;或者,可选地,该线路层也可以为多层金属材质叠加制成,例如,为金属Mo Al Mo叠加制成;其中,该线路层的厚度可以为1nm至999nm,可选为350nm。
步骤604,将第一目标基板与第二目标基板贴合,并沿凹槽的第一侧面切割第一目标基板和第二目标基板,形成为第一基板和第二基板,其中,预设表面形成为第一基板的第一表面,第一侧面形成为第一基板的第三表面的一部分。
本步骤中,基于步骤603在第一目标基板11上形成线路层111后,如图9所示,通过将第一目标基板11和第二目标基板12进行贴合连接,这里,第二目标基板12与第一目标基板11的预设表面贴合连接,然后如图10所示,沿凹槽13的第一侧面对第一目标基板11和第二目标基板12进行切割,以使第一目标基板11和第二目标基板12分别分离形成如图11所示的第一基板110和第二基板120,此时,预设表面即成为第一基板110的第一表面,凹槽13的第一侧面成为第一基板110的第三表面的一部分,第一表面与第三表面连接。
步骤605,将一柔性电路板与第三表面贴合连接,并与线路连接部电连接,得到显示模组。
本公开实施例中,通过将柔性电路板贴合连接于第一基板的第三表面并通过线路层延伸至第三表面的线路连接部实现电连接,从而能够避免该柔性电路板占用第一基板的第一表面的面积,进而减小显示模组的下边框区域尺寸,实现下窄边框设计;并且,利用大片的第一目标基板和第二目标基板来实现线路层的布设,再切割形成为小片的第一基板和第二基板,进而得到显示模组,能够提高显示模组的批量作业效率,节省制造成本。
在本公开一个可选的实施例中,为避免线路层在第一目标基板的预设表 面与凹槽的第一侧面之间的连接处,即弯折位置,容易发生磨损问题,步骤602,在第一目标基板上开设一凹槽之后,该制造方法还可以包括:将凹槽的第一侧面与预设表面的连接处加工成圆弧状。这样,使得后续金属线路镀膜形成的线路层能够呈圆弧状过渡到第一侧边,进而使得第一目标基板切割形成的第一基板的第一表面与第三表面之间与线路连接部相对应的连接处形成为圆弧状。具体地,本公开实施例中,可以将第一目标基板的预设表面与凹槽的第一侧面之间的连接处通过激光雕刻成导圆角,以使两者的连接处加工成圆弧状。
在本公开一个可选的实施例中,步骤605,将一柔性电路板与第三表面贴合连接,并与线路连接部电连接,得到显示模组,可以包括:在第一基板的第三表面涂覆导电胶,使柔性电路板通过导电胶与第一基板的第三表面贴合连接。本公开实施例中,通过在第一基板的第三表面涂覆导电胶,从而能够确保柔性电路板与第三表面之间能够牢固连接并保证柔性电路板与线路连接部之间的电连接。可选地,该导电胶可以为ACF,或者,该导电胶也可以为ACP。
具体地,在本公开一个可选的实施例中,步骤605,将一柔性电路板与第三表面贴合连接,并与线路连接部电连接,得到显示模组,可以包括以下步骤:将柔性电路板的第一部分与第三表面贴合连接,并与线路连接部电连接;将柔性电路板的第二部分弯折至与第一基板的第二表面相对设置;其中,第二表面与第一表面相对,并与第三表面相接。这样,通过柔性电路板的第一部分与第一基板的第三表面贴合连接,以实现柔性电路板与第一基板的牢固连接并确保与线路连接部之间的电连接;同时,通过柔性电路板的第二部分弯折设置于第一基板的第二表面,进而进一步减小显示模组的下边框区域尺寸。需要指出的是,本公开实施例中,柔性电路板的第二部分大于第一部分,在具体示例中,该第二部分可以为柔性电路板的主体部分。
本公开实施例提供的显示模组的制造方法,能够避免该柔性电路板占用第一基板的第一表面的面积,进而减小显示模组的下边框区域尺寸,实现下窄边框设计;并且,能够提高显示模组的批量作业效率,节省制造成本。
