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清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施方式及实施方式中的特征可以相互组合。
实施例
一些已知技术的电子设备，为减小显示屏出线影响屏显面积，其显示屏存在弯折部分，已知技术中显示屏的弯折部分容易受到外力冲击而损坏。例如，对于显示屏外设盖板的电子设备，在朝向盖板的外力作用下，弯折部分由于弯曲影响强度，容易出现较大变形而损坏。本实施例提供屏幕组件，可用于如手机、平板电脑、智能手表、笔记本电脑等电子设备，能够在电子设备受外力时，减小弯折部分的变形，从而降低显示屏受损的可能。
以手机为例，图1示出了的电子设备10(手机)包括屏幕组件11和后盖12。屏幕组件11位于电子设备10的正面，主要用于图像显示。后盖12位于电子设备10的背面，并和屏幕组件11相连接。
配合参见图2，后盖12和屏幕组件11共同围成一内部空间Q1，用于容纳电子设备10的内部元件，如电池13、主板14、主板支架15等。该处所说的“正面”和“背面”仅为电子设备10(手机)的相对概念，并不作为限定，一般以电子设备10的屏幕一侧为正面，而另一侧为背面。
继续参见图2，该实施方式中的屏幕组件11包括显示屏16、盖板17和支架18。显示屏16可以通过引线20电连接至主板14，以实现显示屏16和主板14之间的数据交换，引线20可以采用柔性电路板。
在一些实施方式中，显示屏16和引线20可以设置为一体结构，如将显示屏16的基板(图中未示出)延伸出一定长度以用作引线20的基板，在延伸出的该段基板上布置用于电连接显示屏16和主板14的电路(图中未示出)。在其他实施例中，也可以采用一单独的柔性电路板作为引线20来实现显示屏16和主板14的连接。
其中，盖板17可以是玻璃盖板或其他能够透光的盖板结构，盖板17能够为显示屏16提供一定的保护。盖板17具有相背的第一板面P6和第二板面P5，其中，第一板面P6和第二板面P5分别为盖板17沿厚度方向两侧的表面。图2中示出的第一板面P6朝内，靠近内部空间Q1；第二板面P5朝外，远离内部空间Q1。
显示屏16可以是柔性屏结构，如OLED屏等。显示屏16位于盖板17的第一板面P6一侧(即内侧)，显示屏16包括主屏段16b和弯折段。主屏段16b连接于盖板17内侧，弯折段16a从主屏段16b边缘向远离盖板17一侧弯折形成。
支架18位于显示屏16远离盖板17一侧，并与盖板17围成容纳空间Q2，弯折段16a位于支架18和盖板17之间，并延伸至容纳空间Q2内。容纳空间Q2内设有填充结构19，用于将弯折段16a固定于容纳空间Q2内。主屏段16b连接弯折段16a一端的部分也可伸入容纳空间Q2内并被填充结构19固定在容纳空间Q2内。当然，主屏段16b的外表面(靠近盖板17一侧的表面)未被填充结构19覆盖，以保持显示功能。
本申请实施例中，屏幕组件11的弯折段16a容置在支架18和盖板17围成的容纳空间Q2中，并被填充结构19固定于支架18和盖板17，通过填充结构19使显示屏16较脆弱的弯折段16a、支架18和盖板17固定在一起，能够给与弯折段16a可靠的保护，有效降低弯折段16a受外力冲击损坏的可能。本实施例中，填充结构19可以通过向已容置弯折段16a后的容纳空间Q2内灌胶形成，所灌注的胶可以是在灌注前流动性较好，灌注后可固化(如通过加热固化)的胶材，以实现弯折段16a、支架18和盖板17在弯折段16a附近粘固成一体。
在其他实施例中，填充结构19可替换为胶材之外的无粘合作用的材料。在一些实施例中，可以不设置填充结构19，仅通过支架18对显示屏16的支撑，来提高弯折段16a抗击外界冲击的能力。
对显示屏16进行弯折得到有弯折段16a的显示屏16具有一些使用场景。例如，可以使显示屏16的一侧边缘180°折回，在折回部分的边缘设置前述引线20。如此，引线20位于显示屏16未折回部分的背面，不影响显示屏16正面的显示面积，使显示屏16朝外的面均可用于显示，利于电子设备10获得更大的正面显示区域，乃至得到全面屏的电子设备10。本实施例中的引线20位于电子设备10的底部(以图1的视角)，即显示屏16从电子设备10的底部出线；而在其他实施例中，显示屏16的出线位置也可以是电子设备10的顶部或一侧。
参见图2和图3，本实施例中的支架18包括主架体21、第一凸台22和第二凸台24。
其中，主架体21大致呈板状结构，其延伸方向与盖板17和显示屏16的对应部分的延伸方向趋于一致。例如，图2和图3示出的实施方式中，盖板17和显示屏16在主架体21对应的位置呈弧形，此时，该主架体21大致呈一弧形板状结构。在其他实施方中，主架体21还可设置为其他形状，且不需要和盖板17或显示屏16的延伸方向完全一致。主架体21的厚度可根据需要设定，本实施方式中，主架体21的厚度在0.5-1.0mm，以确保其结构强度并占据较小的空间。
第一凸台22和第二凸台24分别位于主架体21的延伸方向的两端，且彼此间隔地从主架体21朝向盖板17一侧凸出。其中，第一凸台22对应支撑于显示屏16，第二凸台24对应于盖板17，主架体21和盖板17间隔相对，使第一凸台22、主架体21、第二凸台24和盖板17可以共同围成前述的容纳空间Q2，显示屏16的弯折段16a从第一凸台22和盖板17之间的间隙伸入容纳空间Q2内。对于弧形板状的主架体21，第一凸台22和第二凸台24均大致呈条形凸台状。凸出的第一凸台22可以直接或间接地抵顶显示屏16，实现对显示屏16的支撑，凸出的第二凸台24可以直接或间接地抵顶盖板17，实现对盖板17的支撑。第一凸台22和第二凸台24两者可将主架体21撑离显示屏16，使得显示屏16和主架体21之间具有一定厚度的空间，用于填充胶体等材料形成包裹显示屏16的弯折段16a的填充结构19，对弯折段16a起到较好的保护作用。
在一些其他实施方式中，第二凸台24可以取消不设置，而使容纳空间Q2在该端保持开放或由电子设备10的其它结构(如后盖12)封闭。
在一些其他实施方式中，第一凸台22也可以取消不设置，而使容纳空间Q2在该端保持开放或由电子设备10的其他结构封闭。
继续参见图2和图3，本实施例中，第一凸台22对应显示屏16一侧表面为第一表面P1，第一表面P1上凸设有第一支撑垫23，第一支撑垫23抵顶显示屏16，以使第一表面P1和显示屏16之间间隔限定第一缝隙f1(亦可见于图4)，第一缝隙f1连通容纳空间Q2。基于第一支撑垫23，在组装时，可使第一支撑垫23抵顶显示屏16，从而使第一表面P1和显示屏16之间存在连通容纳空间Q2的第一缝隙f1，在向容纳空间Q2内灌胶时，容纳空间Q2内的空气可由第一缝隙f1排出，利于胶材的填充；同时，可通过灌注过量的胶材至使胶材从第一缝隙f1溢出的方式来确保容纳空间Q2内胶材填充满，且留在第一缝隙f1内的胶材可以用于粘接第一表面P1、第一支撑垫23及显示屏16。可选地，第一支撑垫23有多个，多个第一支撑垫23依次间隔设置，填充于第一缝隙f1的胶材可以包裹各个第一支撑垫23。例如，对于弧形板状的主架体21，第一凸台22呈条形凸台状，多个第一支撑垫23可以沿第一凸台22的长向间隔设置。如此，胶材填充至相邻的第一支撑垫23之间，增加了胶材和支架18的接触面积，提高粘接强度。本实施例中的第一支撑垫23可采用柔性材料制成，以避免刚性结构压坏显示屏16或施加过高应力。可选地，第一支撑垫23可以采用软胶结构构成，并具有一定 结构刚度，能保持基本形状，可选地，该第一支撑垫23采用具有一定粘接能力的胶材构成，如热熔胶。如此，在安装该支架18时，可通过加热第一支撑垫23，使第一支撑垫23预粘合于显示屏上，实现支架18的预定位，然后进行向容纳空间Q2灌胶的步骤。当然，对支架18的预定位还可以是通过其他顶压结构将支架18顶压于显示屏16。
在其他实施方式中，第一表面P1可以直接接触显示屏16，而舍去第一缝隙f1的设置；或者，也可以不设置第一支撑垫23，而使第一表面P1和显示屏16之间不直接接触也不通过其他结构支撑，利于保持第一缝隙f1的排除空气和溢胶效果。
再次参见图2，本实施例中，盖板17包括覆盖显示屏16的盖板主体17a和从盖板主体17a靠近弯折段16a一端向外延伸超出弯折段16a的伸出板段17b。盖板主体17a和伸出板段17b可以是一块完整的盖板17的两个区域，其划分位置可以是以显示屏16在盖板17上的延伸末端处，如图2中示出的划分线L1处；或者说，盖板17被显示屏16覆盖的部分定义为盖板主体17a，未对应显示屏16的部分定义为伸出板段17b。第二凸台24对应于伸出板段17b。对于弧形板状的主架体21，第二凸台24大致呈一条形凸台状。凸出的第二凸台24可以直接或间接地抵顶盖板17，和第一凸台22一起实现支架18安装时的定位，并且，第二凸台24和弯折段16a间隔对应，使得填充结构19包括填充于该第二凸台24和弯折段16a之间的部分，能够给与弯折段16a的弯曲点较可靠的保护。在一些实施方式中，第二凸台24具有对应伸出板段17b的第二表面P2，第二表面P2上凸设有第二支撑垫25，第二支撑垫25抵顶伸出板段17b，以使第二表面P2和伸出板段17b之间间隔限定第二缝隙f2，第二缝隙f2连通容纳空间Q2。基于第二支撑垫25，在组装时，可使第二支撑垫25抵顶盖板17的伸出板段17b的内壁，从而使第二表面P2和伸出板段17b之间存在连通容纳空间Q2的第二缝隙f2，在向容纳空间Q2内灌胶时，容纳空间Q2内的空气可由第二缝隙f2排出，利于胶材的填充；同时，可通过灌注过量的胶材至使胶材从第二缝隙f2溢出的方式来确保容纳空间Q2内胶材填充满，且留在第二缝隙f2内的胶材可以用于粘接第二表面P2、第二支撑垫25及伸出板段17b。可选地，第二支撑垫25有多个，多个第二支撑垫25依次间隔设置，使填充于第二缝隙f2的胶材包裹各个第二支撑垫25。例如，对于条形凸台状的第二凸台24，多个第二支撑垫25可以沿第二凸台24的长向间隔设置。如此，胶材填充至相邻的第二支撑垫25之间，增加了胶材和支架18的接触面积，提高粘接强度。本实施例中的第二支撑垫25可采用柔性材料制成，以避免刚性结构压坏显示屏16或施加过高应力。可选地，第二支撑垫25可以采用软胶结构构成，并具有一定结构刚度，能保持基本形状，可选地，该第二支撑垫25采用具有一定粘接能力的胶材构成，如热熔胶。如此，在安装该支架18时，可通过加热第二支撑垫25，使第二支撑垫25预粘合于伸出板段17b上，实现支架18的预定位，然后进行向容纳空间Q2灌胶的步骤。当然，对支架18的预定位还可以是通过其他顶压结构将支架18顶压于伸出板段17b。
在其他实施方式中，第二表面P2可以直接接触伸出板段17b的内侧面，而舍去第二缝隙f2的设置；或者，也可以不设置第二支撑垫25，而使第二表面P2和伸出板段17b的内侧面之间不直接接触也不通过其他结构支撑，利于保持第二缝隙f2的排除空气和溢胶效果。
继续参见图2，本实施例中，后盖12和屏幕组件11之间限定配合间隙f5，通过在配合间隙f5内填充胶合材料形成胶合体29，用于实现后盖12和屏幕组件11的粘合连接。对于图2示出的设置有对应伸出板段17b的第二凸台24的实施方式，屏幕组件11中的第二凸台24对应后盖12的侧面、盖板17对应后盖12的侧面分别和后盖12的对应端面粘合。图2示出的 实施方式中，支架18可先和显示屏16及盖板17连接并灌胶形成一体的屏幕组件11，然后再将屏幕组件11整体与后盖12装配，并在配合间隙f5内填充胶合材料，实现屏幕组件11和后盖12的连接。当然，对于其中设置第二缝隙f2，且容纳空间Q2通过第二缝隙f2连通配合间隙f5的实施方式，还可以通过使容纳空间Q2内的灌胶溢出进入配合间隙f5的方式，一次完成支架18、显示屏16、盖板17和后盖12的粘结，减少组装步骤，提高组装效率。
前述图2-图4示出的实施方式中，第二凸台24的第二表面P2对应于盖板17的伸出板段17b的内侧面，而图5给出了第二凸台24的另一种设置方式。
参见图5，该实施方式中，第二凸台24延伸至盖板17的端面，且第二凸台24的侧面与盖板17的端面相对。该实施方式和图2-图4中的实施方式的不同之处在于，该实施方中的第二凸台24的凸出高度更大，占用了盖板17的厚度空间，且该第二凸台24和盖板17的对应的表面为侧面而非端面(即前述第二表面P2)。可选地，第二凸台24与盖板17的端面相对的表面为第三表面P3，第三表面P3和盖板17的端面之间间隔限定第三缝隙f3，第三缝隙f3连通容纳空间Q2。通过第三缝隙f3，在向容纳空间Q2内灌胶时，容纳空间Q2内的空气可由第三缝隙f3排出，利于胶材的填充；同时，可通过灌注过量的胶材至使胶材从第三缝隙f3溢出的方式来确保容纳空间Q2内胶材填充满，且留在第三缝隙f3内的胶材可以用于粘接第三表面P3及盖板17的端面。对于图5示出的实施方式，第二凸台24远离盖板17的一侧面适配电子设备10的后盖12的端面，后盖12和屏幕组件11之间的配合间隙f5由第二凸台24远离盖板17的一侧面和后盖12对应的端面限定，填充在配合间隙f5内的胶合体29胶合第二凸台24和后盖12。当然，此时容纳空间Q2和该配合间隙f5并不连通。
需要说明的是，对于图5示出的实施方式，其第二凸台24的端面(对应图3中的第二表面P2)可能需要构成电子设备10外轮廓的一部分，因而可以不设置前述第二支撑垫25，对应的支架18的三维结构可参见图6。
继续参见图2该实施方式中，显示屏16包括接线屏段16c和前述的主屏段16b及弯折段16a，主屏段16b为显示屏16用于屏显的部分，接线屏段16c为显示屏16的用于连接引线20的部分，弯折段16a为显示屏16连接于主屏段16b和接线屏段16c之间的部分。主屏段16b贴合于盖板主体17a的内侧面，接线屏段16c位于主屏段16b的内侧面，并与主屏段16b层叠设置，接线屏段16c和主屏段16b之间可以通过胶粘合。伸出板段17b伸出主屏段16b之外。主架体21和接线屏段16c间隔相对，以限定第一填充空间Q3(见于图4)，第二凸台24和弯折段16a间隔相对以限定第二填充空间Q4(见于图4)，第二填充空间Q4连通第一填充空间Q3。第一缝隙f1连通第一填充空间Q3，第二缝隙f2连通第二填充空间Q4，通过向第一填充空间Q3和第二填充空间Q4灌注胶材，填满使第一填充空间Q3、第二填充空间Q4并进入第一缝隙f1和第二缝隙f2，使显示屏16、支架18盖板17三者粘固为一体结构，大大提高了对显示屏16位于容纳空间Q2内的弯折段16a的保护效果，同时，连通容纳空间Q2的第一缝隙f1和第二缝隙f2也利于在灌胶时容纳空间Q2内气体的流出，降低容纳空间Q2里留有气泡影响胶材填充，进而影响粘合效果和缓冲保护效果的可能。
参见图2和图4，在一些实施方式中，弯折段16a在弯折前远离盖板17一侧的表面具有内凹形成凹腔C1。显示屏16在弯折状态下，凹腔C1限定第三填充空间Q5。本实施例中，显示屏16的弯折段16a处的厚度设置得小于主屏段16b，使得弯折段16a的一侧表面相对主屏段16b内凹形成前述凹腔C1。厚度较小的弯折段16a有利于弯折，并且向容纳空间Q2中灌注胶材时，胶材可填充进入凹腔C1限定的第三填充空间Q5，弯折段16a内侧具有胶材， 限制弯折段16a进一步相对靠近地弯折，降低弯折段16a弯折过度导致折角处损坏的可能，结合包裹在弯折段16a外侧面的胶材，能够使弯折段16a较可靠地保持在预设的折弯状态，降低折弯折段16a受外力弯折角度改变影响结构性能的可能。在一些实施方式中，弯折段16a的另一侧表面(弯折段16a在弯折前靠近盖板17一侧的表面)也可设置为相对主屏段16b内凹的结构，使弯折段16a该侧表面和盖板17之间的间距更大，进而增大该间距之间的空间内填充的胶材的厚度，从而使弯折段16a该侧受到足够厚度胶材的保护，进一步提高弯折段16a的使用安全性。
再次配合参见图2，本申请实施例中的盖板17包括平板段17m和弧板段17n。平板段17m为盖板的大致呈平面板状的部分，一般位于电子设备10的正面，对应电子设备10的中间显示区域。弧板段17n为盖板17的从平板段17m的边缘沿弧形方向弯曲延伸形成的部分，弧板段17n的弯曲角度在90至180°，弧板段17n和平板段17m的划分线L2见于图2。该处的弯曲角度即弧板段17n所占据的弧度值。需要说明的是，该处将盖板17人为划分为平板段17m和弧板段17n，和前述将盖板划分为盖板主体17a和伸出板段17b，仅为对盖板17的不同划分方式，并非指盖板17同时独立具备所有区段。如本实施例中，盖板主体17a包括平板段17m和弧板段17n连接平板段17m的部分，伸出板段17b为弧板段17n延伸超出弯折段16a的部分。对应地，显示屏16的主屏段16b包括相连的平面段16m和弯曲段16n，弯折段16a连接于弯曲段16n远离平面段16m一端，平面段16m贴合于平板段17m的第一板面P6所在一侧，弯曲段16n贴合于弧板段17n的第一板面P6所在一侧。显示屏16和盖板17之间的粘合可采用透明的光学胶实现。接线屏段16c的形状包括适配弯曲段16n的弧形，并叠合于弯曲段16n的内侧面，例如通过光学胶粘合于弯曲段16n内侧。弯曲段16n连接弯折段16a的一端处的切线方向和平面段16m的夹角适配前述弧板段17n的弯曲角度，在90至180°范围左右。当然，在一些实施方式中，盖板17的弧板段17n的末端具有伸出板段17b，即这些实施方式中，显示屏16的弯曲角度略小于盖板17的弯曲角度。
在图2-图6示出的实施方式中，弧板段17n的弯曲角度大致为120°，限定了电子设备10侧面的外轮廓，可使电子设备10的正面仅有盖板17可见，方便电子设备10的全面屏设计。对应地，支架18的主架体21沿弧向的延伸角度也约为120°，第一凸台22可支撑在对应显示屏16的平面段16m和弯曲段16n的交界位置，第二凸台24支撑于盖板17的弧板段17n的末端或伸出盖板17并和盖板17的端面对应。
图7-图10示出了另一种实施方式，其和前述图2-图6示出的实施方式的主要不同之处在于弧板段17n的弯曲角度，即图2-图6的实施方式中，弧板段17n的弯曲角度大致为120°，仅延伸至电子设备10的侧面，而图7-图10示出的实施方式中，弧板段17n的弯曲角度大致为180°，不仅限定了电子设备10整个侧面的外轮廓，还延伸至电子设备10的背面。如此，可使电子设备10的从正面和侧面均仅有盖板17可见，也可实现电子设备10的全面屏设计。对应地，支架18的主架体21沿弧向的延伸角度也约为180°，第一凸台22朝上支撑于显示屏16的平面段16m处，第二凸台24朝下支撑于盖板17的弧板段17n的末端(如图示)或伸出盖板17至和盖板17的端面对应。该实施方式下，对应的后盖12只覆盖电子设备10背面的部分区域，可以设置为平板形，而在端部无需弧形翘起，降低了后盖12的设计和加工难度。
在一些其他实施方式中，弧板段17n和弯曲段16n的弯曲角度也可以设置在0-90°。
本申请实施例还提供屏幕组件组装方法，用于形成图2-图6示出的屏幕组件11，或图7-图10示出的屏幕组件11。该屏幕组件组装方法包括：
使支架18和盖板17围成一容纳空间Q2，并使显示屏16弯折形成的弯折段16a容置于容纳空间Q2，然后向容纳空间Q2内灌胶，使支架18、盖板17和弯折段16a粘固为一体。当然，主屏段16b和接线屏段16c与弯折段16a连接的一部分也可容置并被粘结固定于容纳空间Q2中。
对于前述留有第一缝隙f1、第二缝隙f2或第三缝隙f3的实施方式，在向容纳空间Q2内灌胶时，可使胶材从容纳空间Q2填充至第一缝隙f1、第二缝隙f2或第三缝隙f3，以利于容纳空间Q2内的气体排出，以及利于第一缝隙f1、第二缝隙f2或第三缝隙f3两侧结构的粘合。对于溢出第一缝隙f1、第二缝隙f2或第三缝隙f3的胶材，可通过后续工艺清除。
配合参见图11，本申请实施例还提供另一种电子设备10a，包括显示屏16、盖板17以及后盖12a，当然，还可以包括电池13、主板14、主板支架15等常见元件。显示屏16可通过引线20连接至主板14。
该电子设备10a的显示屏16可采用前述电子设备10中的显示屏16，具有弯折形成的弯折段16a。盖板17可以采用前述的盖板17，并位于显示屏16外侧。
配合参见图11和图12，后盖12a包括主盖体26和支撑部27，主盖体26具有对应盖板17的端面P4，端面P4的外侧与盖板17对应。主盖体26和盖板17配合围成内部空间Q1，用于安装电池13、主板14、主板支架15等电子元件，显示屏16位于内部空间Q1内。主盖体26具有朝向盖板17的后盖端部28，支撑部27连接于后盖端部28并伸入内部空间Q1。支撑部27和盖板17围成容纳空间Q2，弯折段16a位于支撑部27和盖板17之间，并伸入容纳空间Q2。容纳空间Q2内设有填充结构19，用于将弯折段16a固定于支撑部27和盖板17。
该电子设备10a，后盖12a的支撑部27和盖板17围成容纳空间Q2并形成填充结构19来实现对显示屏16的支撑和保护，能够有效提高显示屏16的使用安全性。并且，后盖12a组装到位后，仅需一次灌胶粘接，便可同时实现用于保护显示屏16的填充结构19的形成和对后盖12a与盖板17之间的粘合连接，操作步骤减少。
该电子设备10a中，支撑部27为从主盖体26伸出的悬臂状结构，支撑部27的壁厚为0.5-1.0mm。该实施方式中，支撑部27从主盖体26悬臂状伸出，在支撑部27或整个后盖12a采用具有一定弹性的材料(如金属片、具有一定弹性的塑胶材料等)制成时，支撑部27的悬臂伸出部分具有一定弹性变形能力，如此，使得支撑部27对显示屏16的支撑为弹性支撑，从而在起到支撑显示屏16的基础上，能够一定程度上缓冲保护显示屏16。壁厚在0.5-1.0mm的支撑部27，一方面能够保持一定的结构刚度，以提供支撑力，另一方面也具有一定的变形能力，实现对显示屏16的弹性支撑。可选地，后盖12a的支撑部27和主盖体26可以采用塑胶材质一体成型。
该电子设备10a中，支撑部27远离主盖体26的一端具有向显示屏16一侧凸出形成的第一凸台22，用于向盖板17方向支撑显示屏16。该实施方式中，第一凸台22设在支撑部27远离主盖体26的一侧，即在支撑部27的悬臂端，起到弹性支撑显示屏16的作用。可选地，第一凸台22对应显示屏16一侧表面为第一表面P1，第一表面P1上设置有第一支撑垫23，第一支撑垫23抵顶显示屏16，以使第一表面P1和显示屏16之间间隔限定第一缝隙f1，第一缝隙f1连通容纳空间Q2。在向容纳空间Q2内灌胶时，容纳空间Q2内的空气可由第一缝隙f1排出，利于胶材的填充；同时，可通过灌注过量的胶材至使胶材从第一缝隙f1溢出的方式来确保容纳空间Q2内胶材填充满，且留在第一缝隙f1内的胶材可以用于粘接第一表面P1、第一支撑垫23及显示屏16。
该电子设备10a中，支撑部27连接于后盖端部28靠近内部空间Q1一侧，而后盖端部28远离内部空间Q1一侧的端面P4对应于盖板17。
如此，在该电子设备10a组装时，使后盖端部28的端面P4和盖板17的端面之间留有第四缝隙f4，支撑部27伸入显示屏16内侧，并使其第一凸台22的端面和显示屏16之间留有第一缝隙f1，支撑部27和盖板17及后盖端部28之间围成容纳空间Q2，容纳空间Q2和第一缝隙f1、第四缝隙f4分别连通；然后向容纳空间Q2内灌注胶材，填满容纳空间Q2并从第一缝隙f1和第四缝隙f4溢出。对于从第四缝隙f4溢出的胶材，可通过后续工艺去除。填充的胶材可以将后盖12a、弯折段16a及盖板17在容纳空间Q2附近粘结为一体，在完成电子设备10a的后盖12a和盖板17的组装的同时形成对弯折段16a的可靠的保护结构。
综合以上描述，本申请实施例中的屏幕组件11和电子设备10,10a能够形成对显示屏16的弯折段16a的可靠保护，有效降低弯折段16a受外力冲击损坏的可能。
以上实施方式仅用以说明本申请的技术方案而非限制，尽管参照以上较佳实施方式对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换都不应脱离本申请技术方案的精神和范围。
