具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
除非另作定义，本公开实施例使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“连接”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
图1为本公开的一些实施例中提供的显示模组的平面图，图2为沿图1中A-A’线的剖视图，图3为沿图1中B-B’线的剖视图，图4为沿图1中C-C’线的剖视图，如图1至图4所示，显示模组包括：显示面板50、背板10和胶框20。
背板10包括底壁11以及侧边框12，底壁11和侧边框12连接，并限定出容纳空间Va。其中，侧边框12环绕在容纳空间Va周围，可选地，容纳空间Va大致呈长方体结构，这种情况下，侧边框12可以包括多个背板 侧壁121，不同的背板侧壁121位于容纳空间Va的不同侧。
胶框20包括：挡墙21以及设置在挡墙21上的承载台22，挡墙的至少一部分环绕在侧边框12周围。承载台朝容纳空间Va内部延伸，用于承载显示面板。胶框20还包括与挡墙21连接的插件23，插件23位于侧边框12朝向容纳空间Va的一侧，以将侧边框12嵌套在挡墙21与插件23之间。其中，插件23可以与挡墙21直接连接或间接连接，例如，插件23设置在承载台22上，从而通过承载台22与挡墙21连接。
需要说明的是，侧边框12嵌套在挡墙21与插件23之间是指，侧边框12靠近容纳空间Va的一侧以及远离容纳空间的一侧分别设置有挡墙21和插件23，而并不一定表示，插件23和挡墙21是对正的。
当显示面板支撑在承载台22上时，会对承载台22施加一定的压力，导致挡墙21靠近底壁11的一端受到远离容纳空间Va的作用力，尤其是在窄边框显示模组中，挡墙21的厚度减小，强度也会相应的减小，从而导致挡墙21容易向外翘起。而在本公开实施例中，胶框20的挡墙21的至少一部分环绕在背板10的侧边框12周围，挡墙21上设置有插件23，从而使侧边框12嵌套在挡墙21和插件23之间，这种情况下，在显示面板支撑在承载台22上时，即使挡墙21的强度较小，侧边框12、挡墙21和插件23所形成的嵌套结构也可以防止挡墙21发生翘起，从而防止胶框20发生变形，进而提高显示模组的结构稳定性。
在一些实施例中，插件23、承载台22和挡墙21可以形成为一体结构，从而可以提高胶框20本身结构的稳定性。
在一些实施例中，挡墙21包括相连的多个挡墙侧壁211，每个挡墙侧壁211位于容纳空间Va的一侧，不同的挡墙侧壁211位于容纳空间Va的不同侧，并且，每个挡墙侧壁211的至少一部分位于侧边框12远离容纳空间Va的一侧。侧边框12包括：相连的多个背板侧壁121，每个背板侧壁121位于容纳空间Va的一侧，不同的背板侧壁121位于容纳空间Va的不同 侧。例如，显示模组呈矩形，则挡墙21包括四个挡墙侧壁211，侧边框12包括四个背板侧壁121。其中，至少一个挡墙侧壁211上设置有上述插件23。
图5为本公开的一些实施例中提供的其中一个背板侧壁的局部立体示意图，图6为本公开的一些实施例中提供的一个背板侧壁与胶框侧壁装配后的一个局部立体图，图7为本公开的一些实施例中提供的一个背板侧壁与胶框侧壁装配后的另一个局部立体图，其中，图6和图7示出了不同角度的局部立体图，另外，可以理解的是，沿图6中D-D’线剖切得到的截面图如图2中的胶框20和背板10的截面所示，沿图6中的E-E’线剖切得到的截面图如图3中的胶框20和背板10的截面所示，沿图6中的F-F’线剖切得到的截面图如图3中的胶框20和背板10的截面所示。在本公开的一些实施例中，至少一个背板侧壁121和至少一个挡墙侧壁211的结构参照图5至图7中所示，至少一个挡墙侧壁211上设置有插件23，设置有插件23的挡墙侧壁211上包括至少一个缺口部，插件23与缺口部相对设置。其中，缺口部为挡墙侧壁211上进行挖槽而形成的缺口，该缺口可以在挡墙侧壁211的厚度方向上贯穿挡墙侧壁211。具体地，如图7所示，设置有插件23的挡墙侧壁211可以包括第一部分211a和第二部分211b，第一部分211a和第二部分211b限定出缺口部(即图7中，处于两个第一部分211a之间且被第二子侧壁1212所占据的缺口)，插件23与第二部分211b相连，并与缺口部相对设置。设置有插件23的挡墙侧壁211所对应的背板侧壁121采用图5中所示的结构，其包括相连的第一子侧壁1211和第二子侧壁1212，第一子侧壁1211与挡墙侧壁211相对设置，并位于挡墙侧壁211的第一部分211a朝向容纳空间Va的一侧，第二子侧壁1212与插件23相对设置，且第二子侧壁1212的至少一部分位于缺口部中，从而有利于减小显示模组的边框宽度。
如图5所示，第一子侧壁1211朝向容纳空间Va的表面以及第二子侧 壁1212朝向容纳空间Va的表面，分别位于两个平面上，该两个表面之间的间距d可以小于或等于胶框侧壁121的厚度。在一个示例中，该两个表面之间的间距d在0.5mm～1mm之间，从而有利于减小显示模组的边框宽度。例如d为0.5mm，或0.6mm，或0.7mm，或0.8mm，或0.9mm或1mm。
在一些实施例中，第二子侧壁1212远离容纳空间Va的表面与挡墙侧壁211背离容纳空间Va的表面大致位于同一平面上。需要说明的是，两个表面“大致”位于同一平面上是指，两个表面所在平面之间的间距小于一定范围，例如小于0.2mm，或小于0.15mm，或小于0.1mm，或小于0.05mm；当然，两个表面“大致”位于同一平面上可以是指，两个表面完全位于同一平面上。
如图5所示，第二子侧壁1212的两端均通过连接子壁1213与第一子侧壁1211连接，连接子壁1213与其连接的第一子侧壁1211、第二子侧壁1212之间均形成圆弧倒角，以便于背板的制作。例如，在背板的制作过程中，可以先制作具有底壁11和平整侧壁的初始背板，再对平整侧壁中待形成第二子侧壁1212的位置向外冲压，从而形成所需要的背板，其中，受到冲压的部分即为第二子侧壁1212，未被冲压的部分即为第一子侧壁1211，连接在第一子侧壁1211和第二子侧壁1212之间的部分即为连接子壁1213。
其中，如图5中所示，第一子侧壁1211和第二子侧壁1212的高度均大于连接子壁1213的高度，从而在连接子壁1213的位置形成凹槽v1，这种结构设计更有利于对平整侧壁进行冲压而得到第一子侧壁1211、第二子侧壁1212和连接子壁1213。
当第一子侧壁1211和第二子侧壁1212之间设置上述凹槽v1时，如图7所示，挡墙侧壁211的第一部分211a包括拐角部211c，其位于第一部分211a与第二部分211b的相交位置处，且与凹槽v1相对设置，从而提高挡墙侧壁211的结构稳定性。另外，拐角部211c与连接子壁1213、第二子侧壁1212之间可以留有一定的间隙，以便于胶框20和背板10的装配。
如图1所示，在一些实施例中，胶框20的多个挡墙侧壁211包括：多个沿第一方向延伸的第一挡墙侧壁2111和多个沿第二方向延伸的第二挡墙侧壁2112，第一方向与第二方向交叉。其中，第一挡墙侧壁2111“沿第一方向延伸”是指，第一挡墙侧壁2111在背板底壁11所在平面上的正投影整体上是沿第一方向延伸的，即使第一挡墙侧壁2111朝向容纳空间的一侧存在一些凸起或凹陷，也不影响第一挡墙侧壁2111整体的延伸趋势。同理，第二挡墙侧壁2112“沿第二方向延伸”是指，第二挡墙侧壁2112在背板底壁11所在平面上的正投影整体上是沿第二方向延伸的。
第一挡墙侧壁2111的长度大于第二挡墙侧壁2112的长度。例如，显示模组可以为矩形显示模组，此时，胶框的多个挡墙侧壁211包括两个第一挡墙侧壁2111和两个第二挡墙侧壁2112，第一方向与第二方向垂直。需要说明的是，所谓“矩形”可以为直角矩形，也可以为圆角矩形，所述圆角矩形是指矩形的四个顶点中的至少一个是圆角。
在一个示例中，第一挡墙侧壁2111的长度大于第二挡墙侧壁2112的长度，插件23可以仅设置在第一挡墙侧壁2111上，以满足显示模组在“竖屏”使用时的结构强度。“竖屏”使用可以是使用时第二挡墙侧壁2112平行于显示模组的放置面(例如桌面、地面等水平面)延伸。
在一个具体示例中，显示模组尤其适用于医疗系统中，进一步地，该医疗系统可以是医疗拼接显示系统，在医疗拼接显示系统中，多个显示模组可以拼接成更大尺寸的显示屏，该显示屏可以用作医疗诊断类显示屏。例如，至少两个显示模组沿第二方向上并排设置并拼接在一起，第二方向为显示模组处于使用状态时的左右方向，第一方向为显示模组处于使用状态时的高度方向，即，第一挡墙侧壁2111为左右两侧的挡墙侧壁211，第二挡墙侧壁2112为上下两侧的挡墙侧壁211。这种情况下，可以减小显示模组左右两侧的边框宽度，来减小相邻的显示模组之间的拼接缝宽度。当边框宽度较小时，通过在窄边框处的第一挡墙侧壁2111上设置插件23，可 以提高结构的稳定性。另外，在靠近第二挡墙侧壁2112的位置，可以设置灯条和柔性线路板等结构，从而使显示模组对应于第二挡墙侧壁2112的边框(即上下侧边框)较宽。当上下侧的边框宽度较宽时，不易在显示面板的压力作用下发生形变，因此，在第二挡墙侧壁2112上可以不再设置插件。也就是说，在本公开实施例中，插件23可以仅设置在第一挡墙侧壁2111上，从而在提高显示模组结构稳定性的同时，便于显示模组的生产制作。
在一些实施例中，插件23在每个第一挡墙侧壁2111上设置，从而尽可能地提高显示模组的结构稳定性。例如，如上文所示，显示模组为矩形显示模组，此时，两个第一挡墙侧壁2111上在第二方向上并排设置，两个第一挡墙侧壁2111上均设置有插件23，另外，该两个第一挡墙侧壁2111上的插件23的位置可以关于沿第一方向延伸的参考轴镜像对称，从而在显示面板支撑在承载台上时，胶框20两侧的挡墙侧壁211的受力更加平衡，进一步提高结构稳定性。
如图6所示，在一些实施例中，胶框中的插件23分为多个插件组23a，每个插件组23a包括至少一个插件23，同一个插件组23a与同一个第二子侧壁1212相对设置。需要说明的是，图6中仅示意性地示出了挡墙侧壁211上的一个插件组23a，应当理解的是，在该挡墙侧壁211的其他位置，还可以设置其他插件组23a；在其他挡墙侧壁211中，也可以设置插件组23a。
例如，图8为本公开的一些实施例中提供的插件组在胶框中的分布位置示意图，图8中的虚线框表示插件组23a的位置，如图8所示，每个第一挡墙侧壁2111上均设置有多个插件组23a。
在一个具体实施例中，同一个第一挡墙侧壁2111上的多个插件组23a均匀分布，从而使第一挡墙侧壁2111上的受力更加均匀。需要说明的是，同一个第一挡墙侧壁2111上的多个插件组23a均匀分布是指，在同一个第一挡墙侧壁2111上，相邻插件组23a之间的距离相等或大致相等。
在一个示例中，第一挡墙侧壁2111的长度为H，在同一个第一挡墙侧 壁2111上，相邻插件组23a的中心间距H3为H的1/5～1/2倍；优选地，第一挡墙侧壁2111的两端到插件组23a中心的距离H1和H2均为H的1/10～1/6倍。这种情况下，当第一挡墙侧壁2111较长时，则可以将H1、H2、H3设置为较大值，而无需增加插件组23a的数量，从而使第一挡墙侧壁211上的受力更加均匀，同时便于胶框20的生产制作。例如，H1和H2均为H的1/10倍，1/6倍，1/5倍，1/4倍。例如，H3为H的1/5倍，1/4倍，1/3倍，1/2倍。
例如，每个第一挡墙侧壁2111上设置有三个插件组23a，在同一个第一挡墙侧壁2111上，第一挡墙侧壁211的两端到插件组23a中心的距离H1和H2均为H的1/6倍，相邻的插件组23a的中心间距为H的1/3倍。
在另一个示例中，每个第一挡墙侧壁2111上设置有多个插件组23a，每个第一挡墙侧壁2111上的插件组23a数量可以根据第一挡墙侧壁2111的实际长度来确定，第一挡墙侧壁2111的长度越大，插件组23a数量越多；第一挡墙侧壁2111的长度越小，插件组23a数量越少。在同一个第一挡墙侧壁2111上，相邻的插件组23a的中心间距H3小于或等于150mm；优选地，第一挡墙侧壁2111的两端到插件组23a中心的距离H1和H2均小于或等于100mm。这样设置可以防止胶框20在显示面板的压力作用下发生变形。进一步地，当H1、H2和H3过小时，则插件组23a数量较多，不利于生产制作，因此，示例性地，H1和H2可以均在70mm～80mm之间，H3在120mm～130mm之间，从而在防止胶框20发生变形的同时，便于胶框20的生产制作。
在再一个示例中，每个第一挡墙侧壁2111上设置有多个插件组23a。一方面，将相邻的插件组23a的中心间距H3设置为H的1/5～1/2倍，这种情况下，当第一挡墙侧壁2111较长时，插件组23a的数量不会过多，从而便于胶框20的生成制作；另一方面，第一挡墙侧壁2111的两端到插件组23a中心的距离H1和H2均小于或等于100mm，从而在第一挡墙侧壁2111 较长时，防止第一挡墙侧壁2111的两端在显示面板的压力作用下发生变形，提高胶框20的整体稳定性。
图9为本公开的一些实施例中提供的一个背板侧壁与胶框侧壁装配后的局部平面示意图，其中，图9所示的示意图为沿图6中箭头所示的方向观看得到的效果图，如图6和图9所示，每个插件组23a包括间隔设置的至少两个插件23，例如，每个插件组23a包括两个插件23。在一些实施例中，插件23的厚度可以小于第一挡墙侧壁211的厚度，从而有利于实现窄边框并提高产品信赖性，例如，第一挡墙侧壁211的厚度为0.6mm，插件23的厚度为0.4mm，需要说明的是，插件23的厚度为插件23沿第一挡墙侧壁211厚度方向上的最大尺寸。
还需要说明的是，插件23各位置的厚度可以不完全相同，在一些实施例中，插件30包括朝向底壁11方向延伸的第一插件部231和第二插件部232，第一插件部231可以与承载台22连接，第二插件部232位于第一插件部231靠近底壁11的一侧。例如，第一插件部231各处的厚度可以相同。第二插件部232的厚度满足：越靠近底壁的位置厚度越小，这样有利于插件30的成型，并且，可以使第二插件部232具有一定的柔性，从而当容纳空间中的导光板或其他结构件发生膨胀而挤压第二插件部232时，第二插件部232能够为容纳空间中的导光板提供一定的膨胀空间。
其中，第二插件部232朝向容纳空间Va的表面可以为倾斜面，第一插件部231远离容纳空间Va的表面以及第二插件部232远离容纳空间的表面可以处于同一平面上，例如，第一插件部231远离容纳空间Va的表面以及第二插件部232远离容纳空间的表面均与背板侧壁121贴合，这样，可以使胶框20和背板10构成的整体结构更加稳固。
示例性地，第二插件部232靠近底壁11的一端厚度大于或等于第一插件部231厚度的一半。
在一些实施例中，第二插件部232的高度为插件23高度的1/3～1/2，从 而在保证插件23能够为背板10的侧边框121提供一定的支撑力的同时，有利于插件30的成型，并能够在导光板或其他结构件膨胀时提供一定的膨胀空间。例如，第二插件部232的高度为插件23高度的1/3或5/12或1/2。
需要说明的是，第一插件部231/第二插件部232的厚度是指，第一插件部231/第二插件部232在第一挡墙侧壁211厚度方向(即，图3中的X方向)上的尺寸。第一插件部231/第二插件部232的高度是指，第一插件部231/第二插件部232在底壁11厚度方向(即，图3中的Y方向)上的尺寸。
另外，本公开实施例对插件23在第二子侧壁1212上的正投影的形状不做限定，例如，可以为矩形、梯形等结构。
在一个示例中，插件23可以延伸至与底壁11接触。当插件23沿第一方向的尺寸较小，且同一个插件23a中相邻两个插件23之间的距离过小时，插件组23a的整体强度较小，进而导致背板10和胶框20构成的整体结构的稳定性较低，胶框20在显示面板10压力下仍有可能发生变形，为了提高该整体结构的稳定性，在一些实施例中，每个插件23沿第一方向的尺寸W1在5mm～10mm之间，例如W1为5mm，或6mm，或7mm，或8mm，或9mm或10mm。同一个插件组23a中，距离最远的两个插件23之间的最远距离L1大于或等于24mm，从而尽量防止胶框20在显示面板的压力下发生变形。另外，在对应于第二子侧壁1212的位置，可以贴附遮光胶带(具体在下文描述)，当L1过大时，遮光胶带的面积也会相应增大，从而影响外观。可选地，L1在24mm～50mm之间，例如，L1为24mm，或30mm，或35mm，或40mm，或45mm或50mm。需要说明的是，两个插件23之间的最远距离L1是指，两个插件23相距最远的两条边之间的距离。可选地，插件组23a所对应的第二子侧壁1212的长度L0大于上述L1，例如L0在30mm～60mm之间，例如，L0为30mm或40mm或50mm或60mm。其中，第二子侧壁1212的长度L0为第二子侧壁1212在第一方向上的尺寸。
需要说明的是，上述实施例是以每个插件组23a包括多个插件23为例进行说明的，当然，在其他实施例中，也可以将图9中所示的同一个插件组23a中的多个插件23连接为一体结构，也即，插件组23a中包括一个插件23，如图10中所示。在图10中，插件23沿第一方向的尺寸W2在20mm～50mm之间。
在一些实施例中，如图5、图7和图9所示，第二子侧壁1212远离底壁11的一端具有插槽121v，该插槽121v用于对光学膜片进行限位，具体将在下文进行说明。
请继续参阅图2至图4，在一些实施例中，显示模组还包括光学膜片30，光学膜片30例如可以起到匀光作用。例如，光学膜片30的数量为多个，多个光学膜片30可以包括：扩散片、棱镜片等。当然，显示模组还可以包括导光板40和灯条(未示出)，导光板40位于光学膜片30与背板的底壁11之间，其包括朝向光学膜片30的出光面、与出光面相对的底面、以及连接的出光面与底面之间的入光面。背板10的底壁11具有凸部11a，该凸部11a朝向光学膜片30凸出，导光板40可以支撑在凸部11a上。灯条与导光板40的入光面相对设置。其中，可以在导光板40与胶框的其中一个第二挡墙侧壁212之间设置灯条，使灯条的光线从导光板40的一侧射入导光板40；也可以在导光板40与胶框的两个第二挡墙侧壁2112之间均设置灯条，以使灯条的光线从两侧射入导光板40。
图11为本公开的一些实施例中提供的光学膜片的局部平面图，图12为本公开的一些实施例中提供的光学膜片与背板侧壁配合的示意图，如图11和图12所示，光学膜片30包括：主体部30a、以及设置在主体部30a上的避让缺口30c和凸耳30b，主体部30a设置在容纳空间Va中，避让缺口30c用于避让插件23，插件23的一部分位于避让缺口30c中；凸耳30b用于与背板侧壁121进行插接。具体地，结合图7、图11至图12，所示，第二子侧壁1212远离底壁11的一端具有插槽121v，凸耳30b插入插槽121v 中，插槽121v可以在第一方向上、以及第二子侧壁1212的厚度方向上，对光学膜片30进行限位。
其中，插槽121v可以为贯穿第二子侧壁1212的孔洞，而为了便于插槽121v的制作，在本公开的一个示例中，插槽121v可以是向远离底璧11一侧开放的状态，即，插槽121v远离底壁11的一端形成有开口；如上文所述，挡墙侧壁211的第一部分211a和第二部分211b限定出缺口部，且第二子侧壁1212的至少一部分伸入缺口部中，因此，当凸耳30b伸入插槽121v中时，挡墙侧壁211的第二部分211b位于凸耳30b远离背板底壁的一侧，此时，挡墙侧壁211的第二部分211b和插槽121v配合，可以对光学膜片30在其厚度方向上进行限位。
其中，插槽121v在第一方向上的尺寸可以略大于凸耳30b在第一方向上的尺寸，插槽121v在光学膜片30厚度方向上的尺寸略大于多个光学膜片30的凸耳30b的总厚度，以保证凸耳30b能伸入插槽121v中。
另外，凸耳30b插入插槽121v中的深度大于或等于第二子侧壁1212厚度的一半，以防止凸耳30b从插槽121v中脱出。可选地，凸耳30b插入插槽121v中的深度为第二子侧壁1212厚度的0.5倍，或0.8倍或1倍。需要说明的是，凸耳30b插入插槽121v的深度为，凸耳30b伸入插槽121v的部分在第二子侧壁1212厚度方向上的尺寸。
其中，插槽121v和插件23的位置如图9中所示，当插件组23a包括两个插件23时，插件23可以位于两个插槽121v之间；当插件组23a包括更多数量的插件23时，每两个插件23之间可以均设置有插槽121v，从而提高对光学膜片30的限位效果。
在一些实施例中，背板10的底壁11和背板侧壁121可以为一体结构，其可以采用高导热系数的材料形成，从而提高显示模组的散热效果。例如，背板10的导热系数大于或等于138W/m/℃。
图13为本公开的一些实施例中提供的背板的底视图，如图13所示， 背板的底壁11背离容纳空间Va的表面上设置有多个加强筋，例如图13中所示的第一加强筋131和多个互不交叠的第二加强筋132，从而提高背板10的强度。
在本公开中，显示模组可以为立式显示模组，此时上述第一方向为显示模组处于显示模组使用状态时的高度方向，并且，对于单个显示模组而言，其高度大于宽度。这种情况下，背板10需要达到足够高的强度，才能够保证整个显示模组的结构稳定性。另外，如上文所述，显示模组尤其适用于医疗拼接显示系统中，由于医疗系统中对显示画面的画质要求较高，因此，需要保证背板10具有足够高的强度，才能对显示面板50进行稳定支撑，从而保证显示画质。
为了进一步提高背板10的强度，如图13所示，第一加强筋131具有第一环形边界，第二加强筋132具有第二环形边界，每个第二环形边界位于第一环形边界所环绕的区域内。可选地，第一加强筋131的第一环形边界设置在底壁11的边缘位置，从而有利于提高底壁11的整体强度；第二加强筋132的第二环形边界也可以设置为环形，具体可以为矩形环、椭圆形环或不规则环状。
其中，第一加强筋131和第二加强筋132均可以为对底壁11进行冲压形成。例如，将底壁11的部分区域向远离显示面板50的一侧冲压，形成第二加强筋132；将底壁11的部分区域朝向靠近显示面板50的一侧冲压，从而形成第一加强筋131。
在一些实施例中，如图13所示，多个第二加强筋132可以包括：第二顶部加强筋132a、第二底部加强筋132b和多个第二中部加强筋132c，第二顶部加强筋132a和第二底部加强筋132b分别位于多个第二中部加强筋132c沿显示模组高度方向的两侧，即，第二顶部加强筋132a位于多个第二中部加强筋132c上方，第二底部加强筋132b位于多个第二中部加强筋132c下方，多个第二中部加强筋132c沿显示模组的宽度方向设置。这样，当背 板10的左右两端(指图中的左右两端)受到图13中垂直于纸面方向的作用力时，在第二中部加强筋132c的加强作用下，背板10不易发生形变；同样，当背板10的上下两端(指图中的上下两端)受到图13中垂直于纸面方向的作用力时，在第二顶部加强筋132a和第二底部加强筋132b的作用下，背板也不易发生形变。因此，通过上述各个第二加强筋132的设置，可以提高背板10的强度。
在一个示例中，第二顶部加强筋132a和第二底部加强筋132b可以对称或大致对称。多个中部加强筋132c关于对称轴镜像对称，该对称轴沿显示模组高度方向延伸，例如，第二中部加强筋132c的数量为两个，两个第二中部加强筋132c对称设置。
当然，多个第二加强筋132也可以包括：第一左侧加强筋和第二右侧加强筋、以及多个第二中部加强筋，第一左侧加强筋和第二右侧加强筋分别位于多个第二中部加强筋的左右两侧，多个第二中部加强筋沿显示模组的高度方向排列。
图14为本公开的一些实施例中提供的显示模组的平面图，图15为沿图14中I-I’线的剖视图，图16为沿图14中J-J’线的剖视图，图17为沿图14中K-K’线的剖视图，其中，I-I’线对应图1中A-A’线的位置，J-J’线对应图1中B-B’线的位置，K-K’线对应图1中C-C’线的位置，如图14至图17所示，显示面板50支撑在胶框的承载台22上。可选地，承载台22上设置有粘结层221，显示面板50通过粘结层221与承载台22粘结。例如，粘结层211可以为泡棉垫，从而在起到粘结作用的同时，为显示面板50提供缓冲力。
其中，显示面板50包括相对设置的阵列基板51和对盒基板52、以及位于二者之间的液晶层，阵列基板51位于对盒基板52靠近光学膜片30的一侧，且包括衬底和设置在衬底上的薄膜晶体管、像素电极等器件，衬底例如为玻璃衬底。另外，显示面板50还包括第一偏光片53和第二偏光片 54，第一偏光片位于阵列基板51远离对盒基板52的一侧，第二偏光片54位于对盒基板52远离阵列基板51的一侧。其中，第一偏光片53在背板的底壁11上的正投影可以位于承载台22在底壁11上的正投影之外，从而减小显示模组的整体厚度。
显示面板50具有显示区AA和位于该显示区AA周围的周边区NA，其中，显示区AA为显示面板50用于显示图像的区域，显示区AA在底壁11上的正投影位于承载台22在底壁11上的正投影之外，周边区NA在底壁11上的正投影与承载台22在底壁11上的正投影存在交叠。
另外，如图14至图17所示，显示模组还可以包括前框60，该前框60包括：多个前框侧壁61、以及与每个前框侧壁61连接的遮挡部62，多个前框侧壁61环绕胶框设置，遮挡部62位于显示面板50远离底壁11的一侧，其在显示面板50上的正投影位于显示面板50的周边区NA，从而对显示面板50的周边区NA的至少部分进行遮挡。其中，挡墙侧壁211与前框侧壁61一一对应，相对应的挡墙侧壁211和前框侧壁61位于容纳空间Va的同一侧。
其中，显示区AA的边界与遮挡部62的外边界之间的间距即为显示模组的边框宽度。在一些实施例中，显示模组的至少两侧的边框为窄边框，其宽度在4.8mm～5.6mm之间，插件23设置在窄边框侧，从而在实现窄边框的同时，保证显示模组整体结构的稳定性。也就是说，设置有插件23的挡墙侧壁211所对应的遮挡部62的外边界与显示区AA的边界之间存在第三间距d3，该第三间距d3在4.8mm～5.6mm之间，例如为4.8mm，或5.0mm，或5.2mm，或5.4mm或5.6mm。
图18为本公开的一些实施例中提供的显示面板的显示区边界出光示意图，如图18所示，承载台22具有远离挡墙的第一边缘(即，承载台22的内边缘)，该第一边缘在底壁11上的正投影环绕显示区AA在所述底壁11上的正投影。其中，对盒基板52包括基底52a和设置在基底52a上的彩膜 层52b，彩膜层52b位于基底52a朝向液晶层55的一侧，显示区AA可以看做彩膜层52b所在区域。第一边缘与显示区AA的正投影之间存在第二间距d2。将阵列基板51整体的折射率、液晶层55的折射率均看做与阵列基板51的衬底的折射率相同，则容纳空间Va的至少一侧所对应的第二间距d2根据以下公式(1)确定：
Figure PCTCN2022092197-appb-000002
其中，α为显示模组至少一侧的最大视角；t1为阵列基板51和液晶层55的厚度之和；t2为第一偏光片53的厚度；t3为承载台22的厚度；n为阵列基板51的衬底的折射率；α为目标观看角度；β为以目标观看角度入射至显示面板50的光线在显示面板50内的折射角；T为显示模组生产时的累计公差，T≥0.33。例如，
Figure PCTCN2022092197-appb-000003
其中，T 1为胶框20的尺寸公差；T 2为胶框20的组装公差；T 3为显示面板50的切割公差；T 4为显示面板50的组装公差。在一些示例中，T 1在0.2mm～0.3mm之间，T 2在0.1mm～0.2mm之间，T 3在0.2mm～0.3mm之间，T 4在0.15mm～0.2mm之间，T在0.33mm～0.65mm之间。
在一种临界状态下，目标光线刚好照射至彩膜层52b的边界位置，d2达到临界值，该临界值为
Figure PCTCN2022092197-appb-000004
其中，b表示：目标光线的入射位置与第一边缘之间的横向距离，其中，目标光线为最靠近第一边缘的且以α的入射角射向显示面板的光线；c为临界状态下，彩膜层52a的边界位置与入射位置的横向距离。因此，当d2≥b+c时，显示面板的显示区边界位置有角度为α的光线射出，而不会被承载台遮挡。
其中，最大视角是指，在观看显示画面的边界位置时，能够看到边界像素的最大观看视角。当观看视角超过所述最大视角时，显示画面的边界像素处的光线无法进行人眼，从而出现像素缺失。显示模组至少一侧的最 大视角是指，在观看显示画面的至少一侧边界时的最大视角。另外，所谓“视角”是指观看方向与显示面板50厚度方向之间的夹角。当容纳空间Va某一侧对应的d2满足上述公式时，则用户在该侧以小于α的观看视角观看显示画面时，显示画面边界处的光线能够进入人眼，而不会出现边界像素缺失的情况，从而可以满足医疗显示系统中对显示画质的需求。
在一些实施例中，上述“容纳空间Va的至少一侧”可以包括：容纳空间Va的两个长边侧，也即，容纳空间Va靠近第一挡墙侧壁2111的一侧。优选地，上述“容纳空间Va的至少一侧”包括容纳空间Va的两个长边侧和两个短边侧。即，容纳空间Va四侧对应的d2均满足上述公式，此时，当以小于或等于α的观看视角观看显示画面的各边界时，均不会出现像素缺失。
其中，上述α可以根据实际需求来进行设置，在一些实施例中，α为45°，根据上述公式可以确定d2的取值范围。
在一些实施例中，t1为0.4mm，t2为0.358mm，t3为1.1mm，累计公差T为0.33mm，当n为1.52，α为45°时，d2设置为大于或等于1.53mm，例如，可以将d2设置为1.57mm。
需要说明的是，图18所示的光路图是以第一偏光片53在背板的底壁11上的正投影可以位于承载台22在底壁11上的正投影之外为例，进行示意的；而在另一些实施例中，第一偏光片53在背板的底壁11上的正投影也可以与承载台22在底壁11上的正投影交叠，此时，显示区边界的光路如图19所示，图19为本公开的一些实施例中提供的显示面板的显示区边界出光示意图，容纳空间Va的至少一侧所对应的第二间距d2根据以下公式(2)确定：
Figure PCTCN2022092197-appb-000005
其中，各参数含义参见上文所述，这里不再赘述。
在一些实施例中，如图15至图17所示，胶框的承载部22位于光学膜片30上方，光学膜片30在底壁11所在平面上的正投影交叠与承载部22在底壁11所在平面上的正投影交叠，交叠区域的宽度大于或等于0.8mm，从而可以保证光学膜片30的稳定设置，另外，交叠区域的宽度还可以小于或等于3mm，从而有利于窄边框的实现。例如，交叠区域的宽度为0.8mm或1.0mm或1.5mm或1.7mm或2mm或2.5mm或3mm。其中，“交叠区域的宽度大于或等于0.8mm”例如为，交叠区域中各处位置的宽度均大于或等于0.8mm。
在一个具体示例中，在对应于第一子侧壁1211的位置，即图15所示的剖切位置，光学膜片30和承载部22的投影交叠区域的宽度可以为1.7mm。在对应于插件23的位置，即图16所示的剖切位置，光学膜片30和承载部22的投影交叠区域的宽度可以为1.0mm。在对应于插槽121v的位置，即图17所示的剖切位置，光学膜片30和承载部22的投影交叠区域的宽度可以为2.6mm。
如图15至图17所示，显示模组还可以包括：压覆部63和遮光胶带70，压覆部63位于遮挡部62朝向显示面板50的一侧，用于对显示面板50进行固定。遮光胶带70连接背板侧壁121、前框侧壁61和挡墙侧壁211，以防止漏光。其中，遮光胶带70至少与背板侧壁121的第二子侧壁1212连接。
需要说明的是，本公开实施例中，对于诸如“m1～m2”的数值范围的描述，均包括端点值m1和m2。
图20为本公开的一些实施例中提供的医疗拼接显示系统的示意图，如图20所示，医疗拼接显示系统包括拼接在一起的多个显示模组，其中，每个显示模组采用上述实施例中的显示模组。例如，所述医疗拼接显示系统可以用于在医疗诊断时显示诊断图像。
其中，至少两个显示模组沿显示模组的短边方向并排设置并拼接，例 如，如上所述，显示模组包括沿第一方向延伸的第一挡墙侧壁2111和沿第二方向延伸的第二挡墙侧壁2112，第一挡墙侧壁2111的长度大于第二挡墙侧壁2112的长度，这种情况下，至少两个显示模组沿第二方向排列。为了减少拼接系统中的拼接缝的宽度，可以减小第一挡墙侧壁2111或拼接缝处的其他结构件的厚度，而由于第一挡墙侧壁2111上设置有插件23，因此，可以在保证显示模组的结构稳定性的同时，减小拼接缝的宽度。
其中，在医疗拼接显示系统使用时，第一方向可以为医疗拼接显示系统的高度方向。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
