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的技术领域的技术人员通常理解的含义相同。本文中在显示装置及显示屏装置的说明 书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。
本申请的一个方面提供一种显示装置，包括底壳和面罩。所述底壳具有底壳安装面，所述底壳安装面凸设有固定柱，所述固定柱的远离所述底壳安装面的一端开设有固定连接孔；所述面罩具有面罩安装面，所述面罩安装面与所述底壳安装面相对；所述面罩安装面开设有面罩连接孔，所述固定连接孔与所述面罩连接孔连通；其中，所述面罩安装面凸设有相对的第一限位筋和第二限位筋，所述固定柱卡设于所述第一限位筋与所述第二限位筋之间。
如图1和图3所示，一实施例的显示装置10，包括底壳100和面罩200。所述底壳100具有底壳安装面110，同时参阅图2和图4，所述底壳安装面110凸设有固定柱120，所述固定柱120的远离所述底壳安装面110的一端开设有固定连接孔121。同时参阅图5，所述面罩200具有面罩安装面210，所述面罩安装面210与所述底壳安装面110相对。所述面罩安装面210开设有面罩连接孔211，所述固定连接孔121与所述面罩连接孔211连通。在一个实施例中，显示装置进一步包括连接件(图未示)，所述连接件依次穿设于所述面罩连接孔211内及所述固定连接孔121内。同时参阅图4至图8，所述面罩安装面210凸设有相对的第一限位筋220和第二限位筋230，所述固定柱120卡设于所述第一限位筋220与所述第二限位筋230之间。在本实施例中，所述面罩安装面210与所述底壳安装面110平行。在本实施例中，所述固定柱120的远离所述底壳安装面110的一端的端面开设有所述固定连接孔121。
上述的显示装置10，由于在面罩200的面罩连接孔211的两边设置了第一限位筋220与第二限位筋230，在将底壳100与面罩200连接时，固定柱120卡设于第一限位筋220与第二限位筋230之间，即使当底壳100变形时，在第一限位筋220和第二限位筋230对固定柱120限位的作用下，可以实现面罩连接孔211与固定连接孔121的精准配合，即实现面罩200在底壳100上的精准定位，从而能够确保面罩200与位于底壳100和面罩200之间的显示模组精确对位，进而确保显示效果。
为了提升固定柱120与面罩200的连接稳固程度，在其中一个实施例中，所述固定柱120的远离所述底壳安装面110的一端的端面与所述面罩安装面210 抵接。这样固定柱120的端面与面罩安装面210接触，不仅使得固定柱120的更多部分卡设于第一限位筋220与第二限位筋230之间，从而提升了第一限位筋220与第二限位筋230对固定柱120的固定效果，而且固定连接孔121与面罩连接孔211直接连通，使得连接件更加稳固地连接固定柱120与面罩200。
在其中一个实施例中，所述面罩200的所述面罩连接孔211的两边分别设置所述第一限位筋220与所述第二限位筋230，即所述面罩连接孔211开设于所述面罩安装面210的位置位于所述第一限位筋220与所述第二限位筋230之间，即所述面罩连接孔211开设于所述面罩安装面210的位置位于所述第一限位筋220在所述面罩安装面210的投影与所述第二限位筋230在所述面罩安装面210的投影之间，即所述第一限位筋220与所述第二限位筋230分别位于所述面罩连接孔211的两侧。这样固定柱120的固定连接孔121与面罩200的面罩连接孔211连通时，使得固定柱120被面罩连接孔211的外部边缘的两侧的第一限位筋220与所述第二限位筋230卡住。
为了能够卡设固定柱120，在其中一个实施例中，如图8所示，所述第一限位筋220具有第一抵持面221，所述第二限位筋230具有与所述第一抵持面221相对的第二抵持面(图未示)，所述固定柱120分别与所述第一抵持面221及所述第二抵持面抵接，通过第一抵持面221与第二抵持面分别于固定柱120的两侧抵接固定柱120，可以将固定柱120卡在第一限位筋220与第二限位筋230之间。在本实施例中，所述第一抵持面221与所述第二抵持面平行。
为了便于装配固定柱120，在其中一个实施例中，所述第一抵持面221的远离所述面罩安装面210的一端设有第一倒角，所述第二抵持面的远离所述面罩安装面210的一端设有第二倒角，由于第一限位筋220的第一抵持面221与第二限位筋230的第二抵持面分别设有倒角，因此，第一限位筋220的远离面罩安装面210的那端与第二限位筋230的远离面罩安装面210的那端之间的距离最大，因此便于固定柱120逐渐插入第一限位筋220与第二限位筋230之间，即便于装配固定柱120。
为了便于装配固定柱120，在其中一个实施例中，如图8所示，所述第一限位筋220具有第一倾斜面222，所述第一倾斜面222与所述第一抵持面221的远 离所述面罩安装面210的一端连接，所述第一倾斜面222朝远离所述面罩安装面210的方向逐渐向外侧倾斜；所述第二限位筋230具有第二倾斜面(图未示)，所述第二倾斜面与所述第二抵持面的远离所述面罩安装面210的一端连接，所述第二倾斜面朝远离所述面罩安装面210的方向逐渐向外侧倾斜。第一限位筋220的远离面罩安装面210的那端与第二限位筋230的远离面罩安装面210的那端之间的距离最大，因此便于固定柱120逐渐插入第一限位筋220与第二限位筋230之间，即便于装配固定柱120。
为了提升限位筋对固定柱120的固定效果，在其中一个实施例中，所述固定柱120具有相背的第一抵接侧面和第二抵接侧面，所述第一抵持面221与所述第一抵接侧面抵接，所述第二抵持面与所述第二抵接侧面抵接，所述第一抵持面221、所述第一抵接侧面、所述第二抵持面及所述第一抵接侧面均为平面。限位筋的抵持面设置成平面，这样便于制造限位筋，同时固定柱120的抵接侧面为平面时，限位筋与固定柱120的抵持面积较大，限位筋对固定柱120的固定效果较好。在另一实施中，在其他实施例中，所述第一抵持面221、所述第一抵接侧面、所述第二抵持面及所述第一抵接侧面中至少一个为圆弧面。。
为了提升对固定柱120的限位固定效果，在其中一个实施例中，如图6和图8所示，所述面罩安装面210开设有安装槽212，所述面罩连接孔211开设于所述安装槽212的底部，所述面罩连接孔211与所述安装槽212连通，所述固定柱120的远离所述底壳安装面110的一端容置于所述安装槽212内；如图8所示，所述安装槽212具有相对的第一侧壁213和第二侧壁(图未示)，所述第一抵持面221与所述第一侧壁213共面，所述第二抵持面与所述第二侧壁共面。这样除了第一限位筋220的第一抵持面221和第二限位筋230的第二抵持面分别与固定柱120抵接，安装槽212的第一侧壁213和第二侧壁也分别与固定柱120抵接，这样增加了固定柱120被抵持的面积，即提升了对固定柱120的限位固定效果。在其中一个实施例中，所述固定柱120适配插设于所述安装槽212内，即所述安装槽212的侧壁均与所述固定柱120抵接，这样在第一限位筋220、第二限位筋230、第一侧壁213及第二侧壁起主要的抵接限位作用的情况下，再配合安装槽212的其他侧壁对固定柱120抵接，如此进一步提升了对固定柱120 的限位固定效果。
为了便于拆装面罩200和固定柱120同时保证面罩200在底壳100上的定位精度，在其中一个实施例中，所述固定连接孔121和所述面罩连接孔211的内壁分别设有内螺纹，所述连接件设有外螺纹，所述连接件的外螺纹分别与所述面罩连接孔211的内螺纹及所述固定连接孔121的内螺纹配合。通过螺纹连接便于拆装面罩200和固定柱120，同时又保证了面罩200在底壳100上的定位精度。
为了提升面罩200的定位精度，在其中一个实施例中，所述固定柱120、所述固定连接孔121、所述面罩连接孔211、所述第一限位筋220及所述第二限位筋230的数目均为多个，多个固定连接孔121与多个所述面罩连接孔211一一对应连通，每一所述固定柱120卡设于一对所述第一限位筋220与所述第二限位筋230之间。在本实施例中，多个所述固定柱120间隔均匀分布于所述底壳安装面110，多个所述面罩连接孔211间隔均匀分布于所述面罩安装面210。通过设置多个均匀间隔分布的面罩连接孔211及固定柱120，而且多个第一限位筋220与第二限位筋230对多个固定柱120卡设，提升了面罩200的定位精度，提升了面罩200与底壳100的连接稳固程度。
在其中一个实施例中，所述面罩安装面210凸设有多个第三限位筋，所述面罩连接孔211位于多个所述第三限位筋之间，所述固定柱120卡设于多个所述第三限位筋之间。这样，在第一限位筋220和第二限位筋230的基础上增加了多个第三限位筋，使得固定柱120的侧面全部被限位筋抵接，进一步提升了对固定柱120的限位固定效果。
为了进一步提升面罩200在底壳100上的定位精度，在其中一个实施例中，如图5所示，所述面罩连接孔211的数目至少为四个，至少两个所述面罩连接孔211位于所述面罩安装面210的横向中心线215的附近，至少两个所述面罩连接孔211位于所述面罩安装面210的纵向中心线216的附近，所述面罩安装面210的横向中心线215和纵向中心线216相互垂直。在本实施例中，所述底壳安装面110上设有至少四个所述固定柱120，至少四个所述固定柱120与至少四个所述面罩连接孔211一一对应。在其中一个实施例中，位于所述面罩安装 面210的横向中心线215附近的所述面罩连接孔211的两侧的第一限位筋220的第一抵持面221和所述第二限位筋230的第二抵持面分别与所述面罩安装面210的横向中心线215平行。在其中一个实施例中，位于所述面罩安装面210的纵向中心线216附近的所述面罩连接孔211的两侧的第一限位筋220的第一抵持面221和所述第二限位筋230的第二抵持面分别与所述面罩安装面210的横向中心线215平行。这样在面罩安装面210的横向中心线215附近和纵向中心线216附近分布有面罩连接孔211，而且横向中心线215附近的限位筋的抵持面与横向中心线215平行，纵向中心线216附近的限位筋的抵持面与纵向中心线216平行，因此限位筋可以在面罩安装面210的横向中心线215方向和纵向中心线216方向对底壳100的固定柱120限位固定，这样大大提升了面罩200在底壳100上的定位精度。在其中一个实施例中，至少两个所述面罩连接孔211的中心位于所述面罩安装面210的横向中心线215上，至少两个所述面罩连接孔211的中心位于所述面罩安装面210的纵向中心线216上。
在其中一个实施例中，如图5所示，所述面罩200设有多对所述第一限位筋220与所述第二限位筋230，至少一对所述第一限位筋220与所述第二限位筋230沿着竖直方向延伸，至少一对所述第一限位筋220与所述第二限位筋230沿着水平方向延伸。所述竖直方向与所述水平方向垂直。在本实施例中，所述竖直方向与所述纵向中心线216的延伸方向平行，所述水平方向与所述横向中心线215的延伸方向平行。这样，在面罩安装面210的水平方向和竖直方向上分别分布有面罩连接孔211，而且水平方向的限位筋的抵持面与水平方向平行，竖直方向的限位筋的抵持面与竖直方向平行，因此限位筋可以在面罩安装面210的水平方向和竖直方向对底壳100的固定柱120限位固定，这样大大提升了面罩200在底壳100上的定位精度。
在其中一个实施例中，所述底壳安装面110还设有安装柱，所述安装柱的远离所述底壳安装面110的一端的端面开设有安装孔，所述面罩安装面210开设有装配孔，所述装配孔与所述安装孔连通，所述显示装置10还包括安装件，所述安装件依次穿设于所述装配孔内及所述安装孔内。
在其中一个实施例中，所述固定柱120的高度大于所述安装柱的高度。由 于固定柱120需要部分插设安装槽212内，而安装柱没有，因此固定柱120的高度大于安装柱的高度，能够保证面罩安装面210与底壳安装面110平行，即保证了安装在底壳100上的面罩200的平整度。
在其中一个实施例中，所述固定柱120为圆柱体状，所述第一限位筋220与所述第二限位筋230之间的距离大于或等于所述固定柱120的直径。在其中一个实施例中，所述第一限位筋220与所述第二限位筋230之间的距离大于所述固定柱120的直径，即所述第一限位筋220及所述第二限位筋230中的至少一个与所述固定柱120之间具有间隙，这样可以补偿误差，也可以防止固定柱120或限位筋受热膨胀影响固定柱120与限位筋之间的配合。
在其中一个实施例中，所述显示装置10包括多个所述面罩200，多个所述连接件与多个所述面罩连接孔211及多个所述固定连接孔121配合，使得多个所述面罩200定位于所述底壳100上。在其中一个实施例中，多个所述面罩200呈矩阵排列于所述底壳100上。
本申请的另一方面提供一种显示屏装置，包括如上述任一实施例所述的显示装置10。在本实施中，所述显示屏装置还包括显示模组，所述显示模组位于所述面罩200与所述底壳100连接形成的空间中。
上述的显示屏装置10，由于在显示装置10的面罩200的面罩连接孔211的两边设置了第一限位筋220与第二限位筋230，在将显示装置10的底壳100与面罩200连接时，固定柱120卡设于第一限位筋220与第二限位筋230之间，即使当底壳100变形时，在第一限位筋220和第二限位筋230对固定柱120限位的作用下，可以实现面罩连接孔211与固定连接孔121的精准配合，即实现面罩200在底壳100上的精准定位，从而能够确保面罩200与位于底壳100和面罩200之间的显示模组精确对位，进而确保显示效果。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普 通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
