Description

显示组件及电子设备
本申请要求于2022年01月18日提交国家知识产权局、申请号为202220150786.5、发明名称为“显示组件及电子设备”的中国实用新型专利的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示组件及电子设备。
背景技术
随着科学技术的发展，可弯曲的柔性屏的产生使得电子设备得以开发出更多的产品形态。
在相关技术中，上述电子设备的保护盖板通常可弯曲、且厚度较小，这样就会使得保护盖板的抗冲击效果较差。因此，目前在柔性屏的背面设置了支撑板，以利用支撑板对柔性屏进行支撑和保护，提高上述电子设备的抗冲击效果。
但是，上述支撑板具有较大的密度及面积，使得支撑板的重量较大，进而导致电子设备的整体重量大大增加。
发明内容
本申请实施例提供一种显示组件及电子设备，用于降低显示组件及电子设备的重量。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种显示组件，该显示组件包括：显示面板及支撑板。支撑板设置在显示面板的非出光侧。支撑板包括至少一个第一部分，第一部分呈平板状。其中，第一部分包括相连接的平面部及凹槽部，凹槽部远离显示面板的一侧，设置有多个凹槽，沿显示面板的厚度方向，凹槽的深度小于平面部的厚度。
本申请的一些实施例提供的显示组件，通过在显示面板的非出光侧设置支撑板，并在支撑板的第一部分中设置凹槽部，在凹槽部远离显示面板的一侧设置凹槽，并对凹槽在显示面板的厚度方向上的深度进行限定，使得凹槽的深度小于平面部的厚度，可以在确保支撑板具有良好抗冲击效果的同时，有效减小支撑板的重量，进而在确保显示组件具有良好的抗冲击效果的同时，减小显示组件的重量，并减小显示组件所应用的电子设备的重量。
在第一方面的一种可能的实现方式中，平面部包括至少一个吸附子部。该至少一个吸附子部与凹槽部中的多个凹槽错开设置。吸附子部远离显示面板的一侧表面为第一表面，第一表面为连续的平面。这样，可以采用真空吸球吸附的方式，将包括显示面板、支撑板、保护盖板、柔性电路板、COP出线或覆晶薄膜、及贴合胶的模组，从容纳壳中取出，避免工作人员用手拾取(或抠)或用手接触模组，以降低模组的损坏率。而且，可以避免吸球吸盘和吸附子部远离显示面板的一侧表面之间出现漏气的情况，避免出现无法采用真空吸球吸附的方式将模组从容纳壳中取出的情况。
在第一方面的一种可能的实现方式中，平面部中除吸附子部以外的部分为设定部分，设定部分远离显示面板的一侧表面为第二表面。所述第一表面和所述第二表面齐平。沿显示面板的厚度方向，吸附子部的厚度等于设定部分的厚度。这样，可以在采用真空吸球拾取模组、以降低模组的损坏率的同时，避免吸附子部靠近显示面板的一侧表面与平面部的设定部分靠近显示面板的一侧表面之间形成段差，避免对显示面板的结构稳定性形成不良影响。
在第一方面的一种可能的实现方式中，吸附子部与凹槽无交叠。和/或，吸附子部和凹槽之间具有间距。这样有利于确保吸附子部与凹槽部中的多个凹槽错开设置，确保吸附子部的第一表面为连续的平面。
在第一方面的一种可能的实现方式中，吸附子部的形状包括圆形、方形、环形或框形。这样在采用真空吸球吸附拾取模组的过程中，可以确保吸附子部的各位置处均能与吸球吸盘之间产生一定压强，避免出现漏气现象。
在第一方面的一种可能的实现方式中，吸附子部围绕至少一个凹槽。
在第一方面的一种可能的实现方式中，多个凹槽的靠近吸附子部的端部的连线的形状，与吸附子部的靠近该多个凹槽的边界的形状互补。这样，不仅可以确保真空吸球能够成功吸附拾取模组，还可以使得凹槽能够在第一部分中具有较大的面积占比，减小支撑板的重量。
在第一方面的一种可能的实现方式中，凹槽部包括至少两个第一凹槽组，每个第一凹槽组包括至少两个凹槽，吸附子部位于至少两个第一凹槽组之间。这样，有利于将吸附子部设置在靠近支撑板或者模组的中心的位置处，在采用真空吸球吸附拾取模组时，可以避免模组产生较大程度的歪斜。
在第一方面的一种可能的实现方式中，凹槽部还包括第二凹槽组。该第二凹槽组包括至少两个凹槽，且第二凹槽组位于至少两个第一凹槽组之间。吸附子部围绕第二凹槽组。这样，可以在采用真空吸球吸附拾取模组的同时，进一步降低支撑板的重量。
在第一方面的一种可能的实现方式中，凹槽部包括位于相邻两个凹槽之间的隔离子部，隔离子部与吸附子部相连接、且为一体结构。这样，既有利于降低形成吸附子部的难度，又可以减少刻蚀形成凹槽的溶液的量，降低成本。
在第一方面的一种可能的实现方式中，显示组件还包括：保护盖板，中框及柔性电路板。保护盖板设置在显示面板远离支撑板的一侧，中框设置在支撑板远离显示面板的一侧，柔性电路板与显示面板绑定。柔性电路板位于支撑板和中框之间，且柔性电路板在支撑板上的正投影，与至少一个吸附子部相互错开。这样，可以避免柔性电路板对吸附子部形成遮挡，进而可以避免对真空吸球对模组的吸附拾取产生不良影响。
在第一方面的一种可能的实现方式中，相邻两个凹槽之间的间距与凹槽在设定方向上的尺寸之比，大于或等于2:3。其中，设定方向为平行于第一部分所在平面的一个方向。这样，可以确保第一部分中位于任意相邻两个凹槽之间的部分能够提供较好的支撑。
在第一方面的一种可能的实现方式中，相邻两个凹槽之间的间距大于或等于凹槽 在设定方向上的尺寸。这样，可以提高第一部分中位于相邻两个凹槽之间的部分的面积占比，确保支撑板的支撑效果。
在第一方面的一种可能的实现方式中，凹槽包括底面及与该底面连接的侧面。其中，底面与侧面之间的夹角大于或等于90°。这样，在该夹角等于90°时，便于制备形成凹槽G，或者，在该夹角大于90°时，可以避免在底面和侧面的连接处形成应力集中，有利于提高支撑板的使用寿命。
在第一方面的一种可能的实现方式中，多个凹槽呈阵列状设置。这样，可以提高该多个凹槽G的排布规律性，降低制备形成凹槽G的难度。
在第一方面的一种可能的实现方式中，凹槽在第一部分所在平面上的正投影的形状包括条形、曲线形、圆形、椭圆形或方形。这样，可以有效减小支撑板的重量。
在第一方面的一种可能的实现方式中，凹槽在第一部分所在平面上的正投影的形状为条形或曲线形。沿凹槽的长度方向的垂直方向，凹槽部中的多个凹槽并列且间隔设置。这样，可以提高凹槽的排布规律性，有利于在凹槽部中设置较多的凹槽，有效减小支撑板的重量。
在第一方面的一种可能的实现方式中，支撑板包括多个第一部分和至少一个第二部分，第二部分位于相邻两个第一部分之间。第二部分可弯折，并可带动相邻的第一部分绕第二部分转动。这样，可以使得显示组件可折叠，使得显示组件所应用的电子设备可折叠。
在第一方面的一种可能的实现方式中，显示面板具有多个第一显示部及至少一个第二显示部。该第二显示部位于相邻两个第一显示部之间，且第一显示部与第一部分相对，第二显示部与第二部分相对。这样，在第二显示部弯折时，第二部分也会发生弯折，同时，第一部分会对第一显示部形成支撑，第二部分会对第二显示部形成支撑。
在第一方面的一种可能的实现方式中，第二部分中设置有多个开口。这样，可以利用该多个开口减少第二部分中应力的集中，还有可以降低支撑板的重量。
第二方面，本申请一些实施例提供一种电子设备，该电子设备包括：如第一方面中任一可能的实现方式中所述的显示组件。
其中，第二方面所带来的技术效果可参见第一方面中不同设计方式所带来的技术效果，此处不再赘述。
第三方面，提供了一种显示组件，该显示组件包括：显示面板及支撑板。支撑板设置在显示面板的非出光侧。支撑板包括多个第一部分和至少一个第二部分，第二部分位于相邻的两个第一部分之间，第一部分呈平板状，第二部分可弯折，第一部分能够以第二部分为轴转动。第一部分远离显示面板的一侧设置有多个凹槽，沿第三方向，凹槽的深度小于支撑板的厚度，第三方向为显示面板的厚度方向；沿第二方向，凹槽的边沿与第一部分的边沿之间具有第一间距，第二方向为平行于第一部分的转动轴线的方向。
本申请的一些实施例提供的显示组件，通过在显示面板的非出光侧设置支撑板，并在支撑板的第一部分远离显示面板的一侧设置多个凹槽，并对凹槽在显示面板的厚度方向上的深度进行限定，使得凹槽深度小于支撑板的厚度，并且沿第二方向，凹槽 的边沿与第一部分的边沿之间具有第一间距，从而可以在确保支撑板具有良好抗冲击效果的同时，有效减小支撑板的重量，进而在确保显示组件具有良好的抗冲击效果的同时，减小显示组件的重量，并减小显示组件所应用的电子设备的重量。
在第三方面的一种可能的实现方式中，多个凹槽的面积之和与第一部分的面积之比小于或等于1:2。这样一来，多个凹槽的面积占用第一部分的50％，并且由于凹槽的边沿与第一部分的边沿之间具有第一间距。因此，在保证支撑板的支撑强度的同时，能够最大限度的对支撑板进行减重，以减轻显示组件的重量。
在第三方面的一种可能的实现方式中，第一间距为M，M≥0.2mm。
在第三方面的一种可能的实现方式中，第一间距M≥1mm。
在第三方面的一种可能的实现方式中，沿第一方向，凹槽的边沿与第一部分的边沿之间具有第二间距N，N≥0.2mm，第一方向垂直于第二方向和第三方向。
在第三方面的一种可能的实现方式中，第二间距N≥1mm。
在第三方面的一种可能的实现方式中，相邻两个凹槽之间的间距与凹槽在设定方向上的尺寸之比，大于或等于2:3。其中，设定方向平行于第一部分所在平面。这样，可以确保第一部分中位于任意相邻两个凹槽之间的部分能够提供较好的支撑。
在第三方面的一种可能的实现方式中，相邻两个凹槽之间的间距大于或等于凹槽在设定方向上的尺寸。即相邻两个凹槽之间的间距与凹槽在设定方向上的尺寸之比，大于或等于1:1，这样，可以提高第一部分中位于相邻两个凹槽之间的部分的面积占比，确保支撑板的支撑效果。
在第三方面的一种可能的实现方式中，凹槽包括底面及与该底面连接的侧面。其中，底面与侧面之间的夹角大于或等于90°。这样，在该夹角等于90°时，便于制备形成凹槽G，或者，在该夹角大于90°时，可以避免在底面和侧面的连接处形成应力集中，有利于提高支撑板的使用寿命。
在第三方面的一种可能的实现方式中，多个凹槽呈阵列状设置。这样，可以提高该多个凹槽G的排布规律性，降低制备形成凹槽G的难度。
在第三方面的一种可能的实现方式中，凹槽在第一部分所在平面上的正投影的形状包括条形、曲线形、圆形、椭圆形或方形。这样，可以有效减小支撑板的重量。
在第三方面的一种可能的实现方式中，凹槽在第一部分所在平面上的正投影的形状为条形或曲线形。沿第一方向，多个凹槽并列且间隔设置，第一方向垂直于第二方向和第三方向。这样，可以提高凹槽的排布规律性，有利于在凹槽部中设置较多的凹槽，有效减小支撑板的重量。
在第三方面的一种可能的实现方式中，沿第一方向，至少两个凹槽之间的间距与其他凹槽之间的间距不相等。这样，相邻的凹槽之间可以设置为不同的间距，以适应不同的设计需求。
在第三方面的一种可能的实现方式中，显示面板具有多个第一显示部及至少一个第二显示部。该第二显示部位于相邻两个第一显示部之间，且第一显示部与第一部分相对，第二显示部与第二部分相对。这样，在第二显示部弯折时，第二部分也会发生弯折，同时，第一部分会对第一显示部形成支撑，第二部分会对第二显示部形成支撑。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
在本申请实施例中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
在本申请实施例中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
在本申请中，除非另有明确的规定和限定，术语“连接”应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连。此外，术语“耦接”可以是实现信号传输的电性连接的方式，“耦接”可以是直接的电性连接，也可以通过中间媒介间接的电性连接。
在本申请实施例中，“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用如“约”、“大致”或“近似”等描述包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
本申请提供一种电子设备。该电子设备例如为具有柔性显示面板的一类电子设备。示例性的，柔性显示面板可弯折。例如，柔性显示面板的相对两端或者中部可弯折。
在一些示例中，上述电子设备包括但不限于笔记本电脑(notebook)、平板电脑(tablet personal computer)、手机(mobile phone)、膝上型电脑(laptop computer)、个人数字助理(personal digital assistant，简称PDA)、个人计算机、导航仪、车载设备、可穿戴设备(例如智能手表)、增强现实(Augmented Reality，简称AR)设备、虚拟现实(Virtual Reality，简称VR)设备等任何具有显示功能的产品或者部件。本申请实施例对上述电子设备1000的具体形式不做特殊限制。

根据电子设备1000中显示面板1的折叠方向的不同，电子设备1000可以分为内折叠设备和外折叠设备。其中，内折叠设备指的是，电子设备1000能够向显示面板1的出光侧折叠，在电子设备1000处于折叠状态时，显示面板1位于电子设备1000内部，不能被观看到其所显示的图像；在电子设备1000处于展平状态时，显示面板1显露出来，能够被观看到其所显示的图像。外折叠设备指的是，电子设备1000能 够向显示面板1的非出光侧折叠，在电子设备1000处于折叠状态时，显示面板1位于电子设备1000的外侧，能够被观看到其所显示的图像。
需要说明的是，显示面板1的出光侧是指，该显示面板1用于显示图像的一侧。显示面板1的非出光侧是指，显示面板1中与出光侧相背的一侧。关于显示面板1，可以参见下文中的说明，此处不再赘述。
当然，上述电子设备也可以为具有曲面屏的电子设备。其中，“曲面”指的是，电子设备的相对两端向非出光侧弯折，其余部分呈平板状。这样有利于增大具有曲面屏的电子设备可视角度。
在一些示例中，电子设备包括显示组件，显示组件包括显示面板。该显示面板用于进行图像显示。
在电子设备为OLED显示设备的情况下，显示面板则为OLED显示面板。在电子设备为QLED显示设备的情况下，显示面板则为QLED显示面板。在电子设备为量子点光致发光显示设备的情况下，显示面板则为量子点光致发光显示面板。
示例性的，在上述电子设备中，显示面板为柔性显示面板，该柔性显示面板可弯折。也即，在电子设备为可折叠的电子设备的情况下，在电子设备进行展开或折叠的过程中，该柔性显示面板可以随之进行展开或折叠；在电子设备为具有曲面屏的电子设备的情况下，显示面板的相对两端向显示面板的非出光侧弯折，显示面板的其余部分呈平板状。
在一些示例中，显示组件还包括设置在显示面板的非出光侧的支撑板。该支撑板包括至少一个第一部分，且该第一部分呈平板状。
示例性的，支撑板可以包括一个或多个第一部分。例如，在电子设备为具有曲面屏的电子设备的情况下，支撑板可以包括一个第一部分。在电子设备为可折叠的电子设备的情况下，支撑板可以包括多个第一部分。
在一些示例中，第一部分包括相连接的平面部及凹槽部。其中，凹槽部远离显示面板的一侧，设置有多个凹槽。沿显示面板的厚度方向，凹槽的深度小于平面部的厚度。
本申请通过在在支撑板的第一部分中设置凹槽部，并在凹槽部远离显示面板的一侧设置凹槽，可以有效减小支撑板的重量，进而减小显示组件及电子设备的重量。
下面结合附图，以电子设备1000为折叠屏手机为例，对电子设备1000的结构进行示意性说明。图1、图2和图3分别示出了电子设备1000的整体结构，图4示出了图1所示电子设备1000沿A-A＇向的一种剖视结构，图5示出了图1所示电子设备1000沿B-B＇向一种的局部剖视结构。图5中的折线型的虚线，表示省略了电子设备1000的一部分结构。
在一些示例中，如图1、图3、图4和图5所示，电子设备1000包括显示组件100，显示组件100包括显示面板1。
示例性的，显示面板1可以具有多个第一显示部11，每个第一显示部11可以呈平面状或平板状。显示面板1还可以具有至少一个第二显示部12，每个第一显示部11例如呈条状。其中，第二显示部12可以位于相邻两个第一显示部11之间，第二显示部12和该相邻两个第一显示部11相连接，且呈一体结构。
可选地，在电子设备1000进行折叠的过程中，第二显示部12会发生弯折，第一显示部11基本不会发生弯折，且第一显示部11能够以与其连接的第二显示部12为轴进行转动。在电子设备1000处于展平状态时，显示面板1也处于展平状态。第一显示部11和第二显示部12可以沿某一方向，依次交替设置。
第一显示部11的数量和第二显示部12的数量，可以根据电子设备1000的折叠数量而定。例如，电子设备1000仅折叠一次，相应的，第一显示部11的数量可以为两个，第二显示部12的数量可以为一个。又如，电子设备1000可折叠两次，相应的，第一显示部11的数量可以为三个，第二显示部12的数量可以为两个。
示例性的，如图1和图3所示，显示面板1具有两个第一显示部11和一个第二显示部12。第二显示部12位于该两个第一显示部11之间。如图1所示，第一显示部11和第二显示部12可以沿第一方向X依次交替设置，第二显示部12可以沿第二方向Y延伸。如图3所示，两个第一显示部11均能够以第二显示部12为轴进行转动，也就是说，第一显示部11的转动轴线与第二方向Y平行，从而使得显示面板1及电子设备1000能够进行折叠或展开。其中，第一方向X和第二方向Y均平行于显示面板1所在的平面，且第一方向X和第二方向Y之间相互垂直。第三方向Z为显示面板1的厚度方向，与第一方向X、第二方向Y均垂直。
在一些示例中，如图4和图5所示，显示组件100还包括设置在显示面板1的非出光侧的中框3。中框3可以包括中板(例如为金属中板)及沿着金属中板的边缘设置一周的边框。其中，边框在第三方向Z上的厚度大于中板在第三方向Z上的厚度。在第三方向Z上，中板和边框形成两个相背的槽。如图5所示，显示面板1可以位于其中一个槽内，且显示面板1的出光侧与中板相背。
示例性的，边框与中板之间的连接方式包括但不限于为焊接、卡接和一体注塑成型。中板的材料可以包括但不限于铝、铝合金或不锈钢材料等。边框的材料可以包括但不限于金属、玻璃、塑胶或陶瓷等。
可以理解的是，在电子设备1000进行折叠的过程中，中框3也可以同时进行转动。
在一些示例中，如图4和图5所示，显示组件100还包括设置在显示面板1的出光侧的保护盖板4。保护盖板4用于对显示面板1进行保护。
示例性的，保护盖板4可以通过封胶贴合在显示面板1的表面。其中，保护盖板4可以采用透明的薄膜材料制成，这样可以使得保护盖板4具有可弯折性，在电子设备1000进行折叠的过程中，保护盖板4能够随之折叠。保护盖板4的材料包括但不限于聚酰亚胺等。
在一些示例中，如图5所示，显示组件100还包括与显示面板1绑定的柔性电路板5。该柔性电路板5可以位于显示面板1和中框3围成的空腔内。
示例性的，如图14所示，柔性电路板5可以包括多个器件51。其中，器件51可以包括电阻、电容或集成电路(Integrated Circuit，简称IC)等。
可以理解的是，柔性电路板5和显示面板1之间的绑定方式包括多种。例如，柔性电路板5和显示面板1之间，可以采用COP(Chip On Pi)绑定工艺进行绑定，此时，显示组件100可以包括连接柔性电路板5和显示面板1的COP出线6。又如，柔 性电路板5和显示面板1之间，可以采用COF(Chip On Film)绑定工艺进行绑定，此时，显示组件100可以包括连接柔性电路板5和显示面板1的覆晶薄膜6。
在一些示例中，如图4和图5所示，电子设备1000还包括前盖200。前盖200可以位于保护盖板4远离中框3的一侧，且与中框3连接。前盖200可以对显示面板1和中框3之间的连接位置及盖板4与中框3之间的连接位置进行遮挡。其中，前盖200与保护盖板4的表面之间可以具有一定的间距，或者，前盖200与保护盖板4的表面可以接触但不密封，这样在电子设备1000进行折叠的过程中，可以避免前盖200对显示面板1和保护盖板4的弯折造成阻碍。
示例性的，前盖200的材料可以为绝缘材料。
在一些示例中，电子设备1000还包括后盖、电池、光学器件(例如图像采集器)等。后盖可以设置在中框3远离前盖200一侧，并与中框3围成一空腔。电池和光学器件等可以位于中框3和后盖所围成的空腔内。如图14所示，光学器件可以通过支撑板2中的通孔7进行光线采集。关于支撑板2，可以参见下文中的说明，此处不再赘述。
在一些示例中，如图4和图5所示，显示组件100还包括支撑板2。该支撑板2设置在显示面板1的非出光侧，且位于显示面板1和中框2之间。支撑板2和显示面板1之间例如可以通过封胶贴合在一起。
需要说明的是，显示组件100中的COP出线或覆晶薄膜6可以弯折至支撑板2和中框3之间，进而使得显示组件100中的柔性电路板5，位于支撑板2和中框3之间。示例性的，显示组件100还包括贴合胶7，柔性电路板5可以通过贴合胶7与支撑板2贴合在一起。
在显示组件100和电子设备1000受到冲击时，支撑板2能够提供支撑，对显示组件100和电子设备1000进行保护，降低显示组件100受到的冲击力。
在电子设备1000为具有曲面屏的电子设备的情况下，支撑板2例如可以位于后盖和中框之间。
示例性的，支撑板2具有良好的韧性。在显示面板1的进行展开或折叠的过程中，支撑板2可以随之进行展开或折叠。
示例性的，支撑板2具有良好的刚度。支撑板2能够对显示面板1进行支撑，并保持显示面板1的形态。例如，在显示面板1处于展平状态、折叠状态或中间状态时，支撑板2能够使得显示面板1维持在展平状态、折叠状态或中间状态，避免显示面板1的状态发生变化。
支撑板2可以包括至少一个第二部分22，每个第二部分22例如呈条状。支撑板2还可以包括多个第一部分21，每个第一部分21可以呈平板状。其中，第二部分22可以位于相邻两个第一部分22之间，第二部分22和该相邻两个第一部分21相连接，且呈一体结构。需要说明的是，该第一部分21在显示面板1处于展平状态、折叠状态、中间状态或者其他任意状态下时均呈平板状。
可选地，在电子设备1000进行折叠的过程中，第二部分22会发生弯折，第一部分21基本不会发生弯折，且第一部分21能够以与其连接的第二部分22为轴进行转动。在电子设备1000处于展平状态时，支撑板2也处于展平状态。第一部分21和第 二部分22可以沿某一方向，依次交替设置。
示例性的，显示面板1的第一显示部11与支撑板2的第一部分21相对，显示面板1的第二显示部12与支撑板2的第二部分22相对。此处，“相对”指的是，第一显示部11在显示面板1所在平面上的正投影，与支撑板2的第一部分21在显示面板1所在平面上的正投影，至少部分重叠。第二显示部12在显示面板1所在平面上的正投影，与支撑板2的第二部分22在显示面板1所在平面上的正投影，至少部分重叠。
这样在第二显示部12弯折时，支撑板2的第二部分22也会发生弯折，即支撑板2的第二部分22的转动轴线与第二方向Y平行，并且与第一显示部11的转动轴线平行。同时，支撑板2的第二部分22会对第二显示部12形成支撑，支撑板2的第一部分21会对第一显示部11形成支撑。
可以理解的是，支撑板2中，第一部分21的数量和显示面板1中第一显示部11的数量相同，第二部分22的数量和显示面板1中第二显示部12的数量相同。
示例性的，如图6所示，支撑板2具有一个第二部分22和两个第一部分21。第二部分22位于该两个第一部分21之间。第一部分21和第二部分22可以沿第一方向X依次交替设置，第二部分22可以沿第二方向Y延伸。
支撑板2的材料例如包括金属材料。可选地，该金属材料可以包括不锈钢、钛合金等。当然，支撑板2的材料也可以包括其他具有一定韧性和刚度的材料。
金属材料的密度较大，且支撑板2在显示面板1所在平面的上的正投影面积较大，使得支撑板2的重量较大，从而导致显示组件100及电子设备1000的重量较大。
基于此，在一些示例中，如图6及图10-图16所示，支撑板2所包括的多个第一部分21中，至少一个第一部分21包括平面部211和凹槽部212。其中，如图4和图5所示，凹槽部212远离显示面板1的一侧设置有多个凹槽G。在一些实施例中，凹陷部212远离显示面板1的一侧也可以仅设置有一个凹槽G。
示例性的，凹槽部212中的多个凹槽G间隔设置。凹槽部212还包括位于相邻两个凹槽G之间的隔离子部H，该隔离子部H用于将其相对两侧的凹槽G隔开。例如，隔离子部H与平面部211相连接，且呈一体结构。
例如，设置有凹槽部212的第一部分21的数量，可以为一个、两个或更多个。设置有凹槽部212的第一部分21中，可以设置有一个、两个或者更多个凹槽部212。
示例性的，支撑板2包括两个第一部分21。如图6及图11-图15所示，该两个第一部分21中，一个第一部分21设置有凹槽部212。如图10和图16所示，该两个第一部分21中，每个第一部分21均设置有凹槽部212。可以理解的是，相比于未设置凹槽的支撑板，本申请在第一部分21设置凹槽G后，相当于将未设置凹槽的支撑板的一部分进行了去除，这样不仅可以利用支撑板2中未设置凹槽G的部分形成支撑，并对显示组件100及电子设备100提供支撑、提高抗冲击效果，还可以有效减小支撑板2的重量，进而减小显示组件100及电子设备1000的重量。
如图4-图5及图7-图8所示，凹槽G设置在第一部分21远离显示面板1的一 侧。其中，沿垂直于显示面板1的厚度方向，也即，沿第三方向Z，凹槽G的深度小于平面部211的厚度。
示例性的，如图7和图8所示，凹槽G包括底面S1。沿第三方向Z，通过将凹槽G的深度，设置为小于平面部211的厚度，可以确保底面S1和第一部分21靠近显示面板1一侧表面之间具有一定的间距，进而确保凹槽G不会贯穿第一部分21，确保第一部分21靠近显示面板1一侧表面为平整表面。
例如，沿第三方向Z，凹槽G的深度为，平面部211的厚度的二分之一。当然，此处仅为凹槽G的深度的示例，并不对凹槽G的实际深度限定。
可以理解的是，第一部分21靠近显示面板1一侧表面为平整表面，这样第一部分21的各位置与显示面板1之间的间距可以是均一的，可以使得支撑板2与显示面板1能够采用等厚的封胶贴合在一起。在显示组件100及电子设备1000受到冲击时，可以避免在支撑板2和显示面板1之间出现应力集中现象，进而可以避免影响支撑板2的抗冲击效果，避免降低显示组件100及电子设备1000的抗冲击效果。
此外，如图6所示，为避免凹槽部212降低第一部分21的支撑强度，沿上述第二方向Y，凹槽部212包括的多个凹槽G的边沿与支撑板2的第一部分21的边沿之间具有第一间距M。即沿第二方向Y，凹槽G的两端均未延伸至第一部分21与第二方向Y垂直的边沿，并且未贯穿支撑板2的第一部分21上平行于XZ平面的侧壁。这样一来，在凹槽部212的一周均设置有平面部211，以使第一部分21靠近边沿的部分的厚度不会减小，从而避免支撑板2的支撑强度降低。
需要说明的是，沿第二方向Y，凹槽G的边沿与第一部分21的边沿之间具有的第一间距，即凹槽G的边沿与第一部分21的边沿之间具有上述平面部211，从而通过平面部211能够避免支撑板2的边沿处的厚度减小，进而能够避免支撑板2的支撑强度下降。
由此，本申请提供的显示组件100及电子设备1000，通过在显示面板1的非出光侧设置支撑板2，并在支撑板2的第一部分21中设置凹槽部212，在凹槽部212远离显示面板1的一侧设置凹槽G，并对凹槽G在显示面板1的厚度方向上的深度进行限定，使得凹槽G的深度小于平面部211的厚度，可以在确保支撑板2具有良好抗冲击效果的同时，有效减小支撑板2的重量，进而在确保显示组件100及电子设备1000具有良好的抗冲击效果的同时，减小显示组件100及电子设备1000的重量。
此外，在支撑板2的多个第一部分21中的至少一个第一部分21中设置凹槽部212的过程中，可以有选择性的在部分第一部分21中设置凹槽部212，这样在将支撑板2应用至显示组件100及电子设备1000时，可以平衡与不同第一部分21相对应的部分(例如图1中电子设备1000的位于左右两侧的部分)的重量，减小与不同第一部分21相对应的部分的重量差异。
在另一种可能的实施例中，如图9所示，沿第二方向Y，凹槽G也可以仅有一个边沿未贯穿第一部分21的边沿，也就是说，沿第二方向Y，凹槽G仅有一个边沿与第一部分21的边沿之间具有上述第一间隙M。例如，沿第二方向Y，间隔分布有两个凹槽G，分别为第一凹槽Ga和第二凹槽Gb，第一凹槽Ga和第二凹槽Gb分别向相反的方向延伸至邻近的第一部分21的边沿处，并分别贯穿对应的第一部分21的边沿。 即第一凹槽Ga和第二凹槽Gb相邻的两个边沿，均未贯穿第一部分21上对应的边沿。
这样，沿第二方向Y，第一凹槽Ga和第二凹槽Gb虽然分别贯穿了第一部分21的两个边沿，但是，由于第一凹槽Ga和第二凹槽Gb间隔分布，即二者之间具有与平面部211厚度相同的间隔部分，通过该间隔部分依然有利于增加第一部分21的支撑强度。即沿第二方向Y，凹槽G并没有从一侧边沿连续延伸至相对的另一侧边沿，因此，不会降低支撑板2的第一部分21的支撑强度。
在一些实施例中，沿第二方向Y，凹槽G的边沿与第一部分21的边沿之间的第一间距M，M≥0.2mm。例如，第一间距M可以为0.5mm、1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm等。并且，第一间距M沿第一方向X可以处处相等，也可以不相等。本申请对此不作特殊限定。
在一些实施例中，沿第一方向X，凹槽G的边沿与第一部分21的边沿之间具有第二间距N，N≥0.2mm。例如，第二间距N可以为0.5mm、1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm等。并且，第二间距N沿第二方向Y可以处处相等，也可以不相等。本申请对此不作特殊限定。
可以理解的是，上述第一间距M和第二间距N均是指，凹槽G的边沿与第一部分21的边沿之间的最小间距。例如，当凹槽G的边沿为曲线时，以该边沿最靠近第一部分21的边沿的点与第一部分21的边沿之间的间距为准。
并且，由于第一部分21上具有第一间距M和第二间距N，因此，便于在支撑板2上贴合背胶，以使支撑板2与其他部件粘接固定。示例性地，当第一间距M和第二间距N均大于或等于1mm时，在支撑板2上贴合背胶时，由于增加了贴合面积，因此，有利于提升粘接强度，从而能够提升设备的结构可靠性。
此外，在平行于支撑板2的第一部分21的平面内，即XY平面内，多个凹槽G在第一部分21上的覆盖面积之和与第一部分21的面积之比小于或等4:5。例如，多个凹槽G最大可以占用第一部分21的面积的80％，此时，第一部分21上未设置有凹槽G的区域占用第一部分21的面积的20％。并且，上述平面部211围绕凹槽部212一周设置。
这样一来，能够最大限度的对支撑板2进行减重，同时，由于凹槽G的边沿与第一部分21的边沿(包括沿第一方向X的边沿和第二方向Y的边沿)之间具有间距(包括上述第一间距和第二间距)，即平面部211绕多个凹槽G一周形成环形结构，因此，能够保证支撑板2的支撑强度。从而在减小电子设备1000的重量的同时，使显示组件100以及电子设备1000具有良好的抗冲击效果。
需要说明的是，上述凹槽G在第一部分21上的覆盖面积是指，沿第三方向Z，凹槽G的槽口在第一部分21的表面上占用的面积。例如，当凹槽G的槽口面积大于槽底面积时，凹槽G在第一部分21上的覆盖面积是指，凹槽G的槽口在第一部分21上的垂直投影的面积。并且，多个凹槽G的面积之和也可以占用第一部分21的面积的75％、70％、65％、60％、55％、50％、45％、40％等，本申请对此不作具体限定。
在一些实施例中，如图7和图8所示，上述凹槽G还包括与底面S1连接的侧面S2。底面S1和侧面S2之间具有夹角，该夹角大于或等于90°。
在一些示例中，如图7所示，底面S1和侧面S2之间的夹角等于90°。此时，凹槽G的剖视图形可以呈长方形或正方形。
示例性的，本申请可以采用与支撑板2材质相应的溶液(或药水)，对第一部分21的特定位置进行刻蚀，得到包括多个凹槽G的凹槽部212。其中，溶液(或药水)可以在第三方向Z上，对第一部分21进行等量刻蚀，从而使得所形成的凹槽G中，底面S1和侧面S2之间的夹角等于90°。这样便于制备形成凹槽G。
在另一些示例中，如图8所示，底面S1和侧面S2之间的夹角大于90°。此时，凹槽G的剖视图形可以呈梯形。
这样在支撑板2的第一部分21受到冲击时，凹槽G的侧面S2可以对冲击力的传递形成缓冲，避免在底面S1和侧面S2的连接处形成应力集中，有利于提高支撑板2的使用寿命。
在一些示例中，凹槽部212中的多个凹槽G，可以呈阵列状设置。
示例性的，上述多个凹槽G，可以沿第一方向X排列为至少一排，可以沿第二方向Y排列为至少一排。
例如，如图6所示，凹槽部212中的多个凹槽G沿第一方向X排列为一排，沿第二方向Y排列为多排。
又如，如图12所示，凹槽部212中的多个凹槽G沿第一方向X排列为多排，沿第二方向Y排列为多排。
采用阵列状设置上述多个凹槽G，可以提高该多个凹槽G的排布规律性，降低制备形成凹槽G的难度。
上述凹槽G在第一部分21所在平面上的正投影形状包括多种，可以根据实际需要选择设置。
在一些示例中，凹槽G在第一部分21所在平面上的正投影的形状包括条形(如图6和图10所示)、曲线形(如图11所示)、圆形(如图12所示)、椭圆形或方形。
示例性的，如图6、图10和图11所示，在凹槽G在第一部分21所在平面上的正投影的形状为条形或曲线形的情况下，凹槽G的长度方向(或称延伸方向)及排布方式，可以相同或类似。
例如，沿凹槽G的长度方向的垂直方向，凹槽部212中的多个凹槽G并列且间隔设置。
可选地，如图6和图10所示，凹槽G在第一部分21所在平面上的正投影的形状为条形。各凹槽G的长度方向为第二方向Y，凹槽G的长度方向的垂直方向为第一方向X。凹槽部212中的多个凹槽G，沿第一方向X并列且间隔设置。当然，本示例中凹槽G的长度方向也可以与第二方向Y之间具有一定的夹角，该夹角的取值范围可以为0°-90°。
可选地，如图6和图10所示，凹槽G在第一部分21所在平面上的正投影的形状为曲线形。各凹槽G的长度方向，与第一方向X和第二方向Y之间均具有夹角。相应的，凹槽G的长度方向的垂直方向，也与第一方向X和第二方向Y之间均具有夹角。凹槽部212中的多个凹槽G，沿第一方向X并列且间隔设置。当然，本示例中凹槽G 的长度方向也可以为第一方向X或第二方向Y。
采用上述设置方式设置凹槽G，可以使得凹槽部212中除凹槽G以外的部分(也即隔离子部H)呈多个条状，且该多个条状的端部相互连接，不仅可以利用凹槽部212中位于相邻两个凹槽G之间的隔离子部H提供支撑，以确保显示组件100和电子设备1000的抗冲击效果，还可以提高凹槽G的排布规律性，有利于在凹槽部212中设置较多的凹槽G，提高凹槽G在凹槽部212中的面积占比，有效减小支撑板2的重量，有效减小显示组件100及电子设备1000的重量。
示例性的，在凹槽G在第一部分21所在平面上的正投影的形状为圆形、椭圆形或方形的情况下，凹槽G的排布方式，可以相同或类似。
以凹槽G在第一部分21所在平面上的正投影的形状为圆形为例，如图12所示，凹槽部212中的多个凹槽G可以呈阵列状排列，也即，该多个凹槽G可以沿第一方向X排列为多列，沿第二方向Y排列为多行。
采用上述设置方式设置凹槽G，可以使得凹槽部212中除凹槽G以外的部分(也即隔离子部H)呈网格状，不仅可以提高凹槽部212中位于任意相邻两个凹槽G之间的隔离子部H的连续性，确保支撑板2的支撑效果，确保显示组件100和电子设备1000的抗冲击效果，还可以提高凹槽G的排布规律性，有利于在凹槽部212中设置较多的凹槽G，有效减小支撑板2的重量，有效减小显示组件100及电子设备1000的重量。
在一些实施例中，如图7和图8所示，相邻两个凹槽G之间的间距L2与凹槽G在设定方向上的尺寸L1之比，大于或等于2:3。其中，设定方向为，平行于第一部分21所在平面的一个方向。换句话说，该设定方向平行于第一部分21所在平面，即设定方向平行于YX平面。
需要说明的是，相邻两个凹槽G之间的间距L2指的是，相邻两个凹槽G的相邻两个侧面S2之间的间距。设定方向及凹槽G在设定方向上的尺寸L1，与凹槽G在第一部分21所在平面上的正投影的形状相关。例如，凹槽G在第一部分21所在平面上的正投影的形状为条形或曲线形，设定方向为凹槽G的长度方向的垂直方向，凹槽G在设定方向上的尺寸L1为凹槽G相对的两个侧面，在凹槽G的长度方向的垂直方向上的间距。又如，凹槽G在第一部分21所在平面上的正投影的形状为圆形、椭圆形或方形，设定方向为圆形直径方向、椭圆长轴方向或方形对角线方向，凹槽G在设定方向上的尺寸L1为圆形直径值、椭圆长轴值或方形对角线长度值。
在一些示例中，相邻两个凹槽G之间的间距L2与凹槽G在设定方向上的尺寸L1之比，可以为2:3、1:1、4:3或3:2等。
在相邻两个凹槽G之间的间距L2与凹槽G在设定方向上的尺寸L1之比较小的情况下，相邻两个凹槽G之间的间距L2则较小。此时，相邻两个凹槽G之间的跨距较小，在支撑板2或显示组件100受到冲击时，凹槽部212中位于任意相邻两个凹槽G之间的隔离子部H可以形成类似桥墩的支撑。
在相邻两个凹槽G之间的间距L2与凹槽G在设定方向上的尺寸L1之比较大的情况下，相邻两个凹槽G之间的间距L2则较大。此时，相邻两个凹槽G之间的跨距较大，在支撑板2或显示组件100受到冲击时，可以确保凹槽部212中位于任意相邻两 个凹槽G之间的隔离子部H能够提供较好的支撑。
示例性的，凹槽G在设定方向上的尺寸L1的取值范围为0.8mm-1.2mm。其中，凹槽G在设定方向上的尺寸L1可以为0.8mm、0.9mm、1mm1.1mm或1.2mm等。相邻两个凹槽G之间的间距L2的取值范围为0.8mm-1.2mm。其中，相邻两个凹槽G之间的间距L2可以为0.8mm、0.9mm、1mm1.1mm或1.2mm等。
在一些示例中，相邻两个凹槽G之间的间距L2大于或等于凹槽G在设定方向上的尺寸L1。也即，相邻两个凹槽G之间的间距L2与凹槽G在设定方向上的尺寸L1之比，大于或等于1。
示例性的，凹槽G在设定方向上的尺寸L1的取值范围为0.8mm-1.2mm，相邻两个凹槽G之间的间距L2的取值范围为0.8mm-1.2mm。在相同的取值范围中，相邻两个凹槽G之间的间距L2的取值要大于或等于凹槽G在设定方向上的尺寸L1上的取值。
这样可以提高第一部分21中位于相邻两个凹槽G之间的隔离子部H的面积占比，确保支撑板2的支撑效果。
在一些示例中，如图6和图10所示，凹槽部212中的多个凹槽G中，至少一部分凹槽G等间距设置。
也即，上述多个凹槽G整体可以等间距设置。或者，上述多个凹槽G中的一部分可以等间距设置，另一部分非等间距设置。例如，在图10中，沿第一方向，至少两个凹槽G之间的间距与其他凹槽G之间的间距不相等。
在一些实施例中，如图17-图22所示，设置有凹槽G的第一部分21中，平面部211包括至少一个吸附子部213。该至少一个吸附子部213与凹槽部212中的多个凹槽G错开设置。
例如，设置有凹槽G的第一部分21可以包括一个、两个、三个、四个或者更多的吸附子部213。凹槽G未贯穿或延伸至吸附子部213，且凹槽G在支撑板2所在平面上的正投影，与吸附子部213在支撑板2所在平面上的正投影，无重叠。
在一些示例中，如图18和图21所示，吸附子部213远离显示面板1的一侧表面为第一表面。该第一表面为连续的平面。其中，“连续”指的是，第一表面是未断开的。“平面”指的是，第一表面的平整度较高，基本无凹凸不平的现象。其中，图18和图21示意出了支撑板2中的第一部分21，未示意出显示面板1，结合图4和图5可知，显示面板1位于支撑板2下方。
这样有利于可以确保吸附子部213远离显示面板1的一侧表面为较为平整的表面。
需要说明的是，在组装显示组件100的过程中，会先将显示面板1、支撑板2、保护盖板4、柔性电路板5、COP出线或覆晶薄膜6、及贴合胶7组装到一起，构成一模组，再将该模组与中框3、前盖200等进行组装。在对模组进行运输的过程中，为了避免柔性电路板5中的器件51等受到磕碰而损坏或产线出现倒扣组装情况，会将模组放在容纳壳(或称保护壳)内，且保护盖板4朝下、柔性电路板5朝上放置。在将模组与中框3、前盖200等进行组装时，需要将模组从容纳壳中取出。
本申请可以采用真空吸球(如图23所示)吸附的方式将模组取出。例如，可以 捏住真空吸球的吸球圆头，排除吸球圆头中的空气，然后将真空吸球的吸球盘放在吸附子部213的位置，松开吸球圆头。吸球圆头内形成低压区，吸球圆头外部形成外界高压区，吸球圆头内外的压差，使得吸球盘和吸附子部213的第一表面之间形成一定的压强，进而使得两者贴附在一起。通过拿起真空吸球，也便可以从容纳壳中取出模组。这样可以避免工作人员用手拾取(或抠)或用手接触模组，以降低模组的损坏率。
而且，本申请通过将吸附子部213和凹槽G错开设置，且将吸附子部213的第一表面设置为连续的平面，可以避免吸球吸盘和吸附子部213的第一表面之间出现漏气的情况，避免出现无法采用真空吸球吸附的方式将模组从容纳壳中取出的情况。
可以理解的是，在拾取模组的过程中，每个吸附子部213上均可以设置真空吸球。在吸附子部213的数量为多个的情况下，可以采用多个真空吸球对模组进行吸附拾取。这样有利于提高吸附拾取的成功率。
在一些示例中，吸附子部213与凹槽部212中的多个凹槽G无交叠。和/或，吸附子部213和凹槽部212中的多个凹槽G之间具有间距。
也即，吸附子部213及与其相邻的凹槽G之间未接触，且凹槽G未伸入至吸附子部213内。
这样有利于确保吸附子部213与凹槽部212中的多个凹槽G错开设置，确保吸附子部213的第一表面为连续的平面。
在一些示例中，如图18和图21所示，平面部211中除吸附子部213以外的部分为设定部分，设定部分远离显示面板1的一侧表面为第二表面，该第二表面和上述第一表面齐平。沿显示面板1的厚度方向，也即第三方向Z，吸附子部213的厚度等于设定部分的厚度。
由于吸附子部213的第一表面与设定部分的第二表面齐平，且吸附子部213的厚度与设定部分的厚度相等，因此，吸附子部213靠近显示面板1的一侧表面与设定部分靠近显示面板1的一侧表面，也齐平。这样可以采用真空吸球拾取模组、以降低模组的损坏率的同时，避免吸附子部213靠近显示面板1的一侧表面与设定部分靠近显示面板1的一侧表面之间形成段差，避免对显示面板1的结构稳定性形成不良影响。
在一些示例中，如图18和图21所示，凹槽部212中位于相邻两个凹槽G之间的隔离子部H，与吸附子部213相连接、且为一体结构。
也即，在第一部分21远离显示面板1的一侧形成凹槽部212(也即形成凹槽G)的过程中，可以对待形成吸附子部的区域进行规划，不对待形成吸附子部的区域进行刻蚀，仅对其他位置进行刻蚀，便可以自然而然地形成吸附子部213。这样既有利于降低形成吸附子部213的难度，又可以减少刻蚀形成凹槽G的溶液的量，降低成本。
在一些示例中，如图17、图19、图20和图22所示，凹槽部212中的多个凹槽G的靠近吸附子部213的端部的连线的形状，与吸附子部213的靠近该多个凹槽G的边界的形状互补。
这样可以减小凹槽部212中的多个凹槽G的靠近吸附子部213的端部的连线，与吸附子部213的靠近该多个凹槽G的边界之间的间距，不仅可以使得吸附子部213的面积与吸球吸盘相对应，以确保真空吸球能够成功吸附拾取模组，还可以使得凹槽部 212能够在第一部分21中具有较大的面积占比，减小支撑板2的重量，减小显示组件100及电子设备的重量。
在一些示例中，如图17、图19、图20和图22所示，吸附子部213的形状包括圆形(如图17所示)、方形(如图22所示)、环形(如图19所示)或框形(如图20所示)。
这样在采用真空吸球吸附拾取模组的过程中，可以确保吸附子部213的各位置处均能与吸球吸盘之间产生一定压强，避免出现漏气现象。
可以理解的是，吸附子部213的形状并不局限于上述举例，具体可以根据真空吸球的大小、尺寸或形状等灵活设置。
在一些示例中，如图20所示，吸附子部213围绕至少一个凹槽G。
示例性的，凹槽G的形状为环形或框形。凹槽部212的多个凹槽G中，一个凹槽G、两个凹槽G甚至所有的凹槽G，可以设置在吸附子部213内部，被吸附子部213环绕。
此处，吸附子部213围绕的凹槽G的数量，可以根据实际需要选择设置，能够不影响真空吸球对模组的吸附拾取即可。
在一些示例中，如图17和图19所示，凹槽部213包括第一凹槽组G1，该第一凹槽组G1的数量可以为至少两个。其中，每个第一凹槽组G1包括至少两个凹槽G。
第一凹槽组G1的数量可以为两个、三个或者更多个。每个第一凹槽组G1所包括的凹槽G的数量可以为两个、三个或者更多个。上述至少两个第一凹槽组G1例如可以沿第二方向Y依次排列。当然，该至少两个第一凹槽G1也可以有其他的排列方式。
吸附子部213位于上述至少两个第一凹槽组G1之间。例如，沿第二方向Y，上述至少两个第一凹槽组G1排列为一列，吸附子部213位于其中两个第一凹槽组G之间。此时，吸附子部213的形状可以为圆形、方形、环形或框形。
这样有利于将吸附子部213设置在靠近支撑板2或者模组的中心的位置处，在采用真空吸球吸附拾取模组时，可以避免模组产生较大程度的歪斜。
在一些示例中，如图20所示，吸附子部213还还包置有第二凹槽组G2，第二凹槽组G2包括至少两个凹槽G。每个第二凹槽组G2所包括的凹槽G的数量可以为两个、三个或者更多个。
示例性的，第二凹槽组G2位于上述至少两个第一凹槽组G1之间。例如，上述两个第一凹槽组G1沿第二方向Y依次排列，第二凹槽组G2可以位于其中两个第一凹槽组G1之间，与该至少两个第一凹槽组G1共同排列为一列。
如图20所示，吸附子部213围绕该第二凹槽组G2。此时，吸附子部213的形状可以为环形或框形。
第二凹槽组G2的数量例如可以与吸附子部213的数量相同，这样每个吸附子部213均可以围绕一个第二凹槽组G2。
通过使得吸附子部213围绕第二凹槽组G2，可以在采用真空吸球吸附拾取模组的同时，进一步降低支撑板2的重量，降低显示组件100及电子设备的重量。
需要说明的是，如图17所示，显示组件100中的柔性电路板5，在支撑板2上 的正投影，与至少一个吸附子部213相互错开。也即两者无交叠。
这样可以避免柔性电路板5对吸附子部213形成遮挡，进而可以避免对真空吸球对模组的吸附拾取产生不良影响。
在一些示例中，如图17所示，支撑板2的第二部分22中设置有多个开口K。该多个开口K可以贯穿支撑板2。这样在电子设备100进行折叠，以使得支撑板2的第二部分22弯折的过程中，可以利用该多个开口K减少第二部分22中应力的集中。而且，通过设置该多个开口K，还有利于降低支撑板2的重量，降低显示组件100及电子设备的重量。
