本申请提出一种显示模组，该显示模组可以应用于诸如电脑显示器、电视机等显示设备中。
参照图1，在本申请一实施例中，该显示模组包括：

进一步地，显示屏2的侧边与侧壁12的外侧面相平齐，以使得从前视角看显示模组时，完全看不到背板1的侧壁12，只能看到显示屏2，从而实现严格意义上的全面屏，提高用户体验。当然，于其他实施例中，为实现全面屏，显示屏2的侧边也可突出于侧壁12的外侧面。
参照图2，在本实施例中，进一步地，光学膜片组3包括邻设在显示屏2内侧的第一膜片31，该第一膜片31的边缘设有侧凸311；侧壁12的自由端端面上设有连通所述安装空间的安装沉槽101，第一膜片31的侧凸311卡入该安装沉槽101，以给该第一膜片31提供定位和一定的支撑安装；可以理解，安装沉槽101是相对侧壁12的自由端端面凹设的，且其贯穿侧壁12的内侧面，以连通所述安装空间，并使得侧凸311能通过所贯穿的位置卡入该安装沉槽101。本实施例中，侧壁12通常设有多个，该多个侧壁12通常包括左侧壁、右侧壁和顶侧壁，安装沉槽101通常设置在顶侧壁的自由端端面上。不失一般性，该第一膜片31可以是增亮膜、扩散膜等。一并参照图3，本实施例中，相邻两侧壁12各自的自由端端面在背板1的角落处平滑过渡，无需焊接，节省工序。需要说明的是，在第一膜片31的内侧，光学膜片组3还可包括具有其他光学性能的第二膜片、第三膜片等。
本实施例中，通常地，侧壁12自由端端面上安装沉槽101的槽深不小于侧凸311的厚度，以避免侧凸311妨碍显示屏2内侧面的边缘与侧壁12自由端端面之间的安装。当然，在某些特殊情况下，也可以允许侧凸311的厚度略大于安装沉槽101的槽深，只要侧凸311的厚度不大于安装沉槽101的槽深与粘接层（双面胶41或者黏性胶）的厚度之和即可。
本实施例中，进一步地，侧凸311上开设有挂孔312，安装沉槽101上设有挂凸102，侧凸311通过挂孔312与安装件的挂凸102挂接配合，能方便地实现第一膜片31在侧壁12自由端端面上的安装。然本设计不限于此，于其他实施例中，第一膜片31的侧凸311还可粘固于安装沉槽101。可选地，侧壁12自由端端面上安装沉槽101的面积大于第一膜片31上侧凸311的面积，以便于装配；类似的，侧凸311上的挂孔312通常大于安装沉槽101上的挂凸102。
需要说明的是，本实施例中，安装沉槽101和挂凸102可以是在成型背板本体11和侧壁12时一体成型的（即是说，在注塑或铸造成型背板本体11和侧壁12时，同时成型出安装沉槽101和挂凸102），也可以是在成型背板本体11和侧壁12之后，再在侧壁12的自由端端面通过铣槽工艺实现的（即是说，在注塑或铸造成型背板本体11和侧壁12之后，后续进一步铣槽加工出安装沉槽101和挂凸102）。
参照图1，在本实施例中，进一步地，光学膜片组3还包括设在显示屏2内侧的导光板32，侧壁12的内侧设有定位件42，导光板32的侧边与定位件42相抵接，以便于导光板32的定位安装。不失一般性，第一膜片31位于导光板32与显示屏2之间；通常地，为提高背光效率，光学膜片组3还包括设于导光板32与背板本体11之间的反射片33。本实施例中，通常地，背板本体11的底边空置，以安装背光灯条；左侧壁、右侧壁和顶侧壁的内侧均设有所述定位件42，以对导光板32进行定位，避免导光板32的晃动。然本设计不限于此，于其他实施例中，定位件42还可以设置在远离背板本体11底边的两个角落处。
本实施例中，可选地，定位件42安装于侧壁12的内侧面。然本设计不限于此，于其他实施例中，定位件42也可安装于背板本体11的内侧面，当然，通常地，此时定位件42会邻近侧壁12设置。
本实施例中，进一步可选地，定位件42可拆卸安装于背板1，以便于定位件42的损坏更换。一并参照图4，通常地，本实施例中的侧壁12较厚，可利用侧壁12的厚度，在侧壁12的内侧面设置嵌槽121，如此，定位件42的一侧可通过嵌设的方式嵌固在嵌槽121中，以避免定位件42对所述安装空间的空间作过多的占用，也可减少定位件42显露在显示屏2下方的体积，从而降低显示屏2边缘出现小黑区的概率；当然，定位件42的另一侧与导光板32的侧边相抵接。
然本设计不限于此，于其他实施例中，定位件42还可粘固于背板1；而对于定位件42粘固于背板1的方式，可选地，定位件42包括与侧壁12的内侧面贴合安装的第一定位块、及自第一定位块靠近背板本体11的侧边折弯延伸成型的第二定位块，该第二定位块的自由端与导光板32的侧边抵接；可以理解，第一定位块可为定位件42提供更大的与侧壁12内侧面连接的面积，从而使定位件42在侧壁12上的安装更为稳定。
进一步地，本实施例中，定位件42设置为弹性定位件，即是说，定位件42具有弹性，以避免导光板32与定位之间出现因零件公差所带来的难以匹配安装的现象。可选地，定位件42可以设置为橡胶件、硅胶件等。另外，为避免定位件42吸光而影响背光效果，定位件42设置可为白色橡胶件。
本申请还提出一种电视机，该电视机包括显示模组，该显示模组的具体结构参照上述实施例，由于本电视机采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
