Description

显示模组和中框 技术领域
本公开的实施例涉及一种显示模组和中框。
背景技术
大尺寸的显示装置，例如，户外显示屏已经广泛应用于各类视频控制中心、户外广告等领域。由于单个显示器件的尺寸很小，因此，户外显示屏一般由多个相对小尺寸的显示单元排布而成，多个显示单元协同用于显示一个整体的画面，且由于无边框或者窄边框显示可以为用户提供更加震撼的视觉体验，已经成为当下显示的潮流。
然而，每个显示单元都包括边框，每个显示单元的边框的宽度会直接影响拼接后形成的拼接屏的拼缝的宽度，从而会影响拼接屏的拼缝处的亮度，导致整个户外显示屏显示的画面被边框分割，造成画面显示不连续，进而会影响拼接屏整体的显示效果，因此，拼接屏对边框的亮度的要求更高。

为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开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。“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“相连”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。
在大屏幕显示领域，由于100英寸以上的超大尺寸显示屏的生产成本远高于例如55英寸的大尺寸显示屏，由于受到制备工艺和目前能够采用的设备的限制，目前最大尺寸的显示屏一般能够做到110寸，因此，通过多屏拼接形成大屏，并进行图像显示得到了广泛的应用。
液晶拼接屏具有高亮度、高色彩饱和度以及高对比度等特点，然而，由于液晶显示面板中的液晶是具有流动性的，需要使用封框胶将液晶封闭在特定区域的位置内，且封框胶部分不能用于显示。此外，在玻璃切割工艺中需要为面板的研磨预留一定的距离以保证像素区域能够进行正常的显示。这使得拼接后的液晶显示面板在显示时存在一条无法完全消除的“拼缝”。小间距迷你发光二极管(Mini LED)或者微发光二极管(Micro LED)使得发光二极管显示在拼缝处的分辨率降低，但是对比度以及亮度方面都显现出很高的优势，随着小间距发光二极管显示技术的工艺成本不断降低，面对日趋激烈的竞争压力，液晶显示面板相关行业的研究人员在工艺、结构、光学等方面不断升级优化，实现了拼接屏拼缝宽度从“3.Xmm”到“1.Xmm”再到“0.Xmm”的跨越，但是“拼缝”视觉宽度的减少和其周边画面的优化仍然是目前拼接屏显示的关键性技术点。
目前，窄边框液晶拼接屏中的背光模组通过在边缘进行涂覆粘合胶的方式与显示面板进行贴合，考虑到粘着力和产品的信赖性测试要求，粘合胶的有效贴合宽度大约为1mm，所使用的粘合胶理论的光学透过率在73％-85％之间，因此，最终产品的画面往往在边缘涂胶区域呈现出发暗的现象，且越靠近边缘亮度越暗。同时，受到加工过程和组装工艺的影响，以及受到涂覆胶贴合设备工作过程的影响，发暗区域会出现亮度不均的问题，在终端产品 拼接完成后该不良产生的叠加情况会影响显示模组整体的视觉效果。通过使得背光模组内表面的光线反射角度的优化，贴合胶承载面的宽度降低，将发光二极管进行非等间距设计，以及采用透明材质替代非透明材质可以在正视角下改善暗框不良的现象，但是上述方法都无法从根本上以及在斜视角度下消除暗框不良的现象。另一方面，在极窄拼缝产品的基础上发展的无缝显示产品利用2.5D玻璃，即通过使得一般玻璃的边缘具有弧度而使得该2.5D玻璃对背光源发射的光线进行折射，以实现放大图像的效果，但是由于上述原因造成的实际边缘像素亮度发暗不均，应用2.5D玻璃进行无缝显示的效果难以得到提升。
本公开的发明人注意到，因为显示模组边缘像素发暗不均造成的亮度问题在视觉上会加重拼接屏存在拼缝的问题，通过改变背光模组包括的中框的结构可以提升边缘像素的亮度和均一度，并搭配2.5D玻璃的折射作用能够实现接近无缝显示的效果。
本公开至少一实施例提供一种显示模组，该显示模组包括：背光模组和显示面板，该背光模组包括背板、第一光源和中框。该背板包括底板，该第一光源设置在底板上，该中框设置在底板与显示面板之间，该中框的靠近显示面板的一侧具有第一承载部和第二承载部，该第一承载部在中框的边缘处，且第一承载部上设置有第二光源，该第二承载部在第一承载部的靠近显示面板的显示区域的一侧，且第二承载部与显示面板的对应于显示区域的位置连接，该显示模组的结构简单、成本较低，且能够避免暗框不良的现象。
例如，图1为本公开至少一实施例提供的一种显示模组的截面结构示意图，如图1所示，该显示模组10包括：背光模组101和显示面板102，该背光模组101包括背板1011、第一光源1012和中框1013。该背板1011包括底板1011a，该第一光源1012设置在底板1011a上，该中框1013设置在底板1011a与显示面板102之间，该中框1013的靠近显示面板102的一侧具有第一承载部1013a和第二承载部1013b，该第一承载部1013a在中框1013的边缘处，且第一承载部1013a上设置有第二光源1014，该第二承载部1013b在第一承载部1013a的靠近显示面板102的显示区域的一侧，且第二承载部1013b与显示面板102的对应于显示区域的位置连接，将中框1013与显示面板102连接的位置设置在显示区域，而在非显示区域设置至少两个第二光源1014，可以改善边缘像素画面发暗的问题。
例如，第一承载部1013a的表面和第二承载部1013b的表面均与显示面板的表面平行。
例如，尽管图1中示出了该第一承载部1013a和显示面板102之间的空隙的截面形状为矩形缺口，该第一承载部1013a与显示面板102之间的空隙的截面形状也可以是非矩形的结构，还可以是圆形、椭圆形等，本公开的实施例对此不作限定。
例如，如图1所示，该显示面板102与背光模组101通过第一粘合胶103粘结在第二承载部1013b的位置进行连接，具体地，背光模组101包括的中框1013的靠近显示面板102的表面与显示面板102通过第一粘合胶103进行粘结。该第一粘合胶103可以覆盖整个第二承载部1013b，也可以覆盖第二承载部1013b的一部分，本公开的实施例对此不作限定。
例如，如图1所示，该显示模组10还包括设置在第一承载部1013a上的灯板1015，该第二光源1014包括设置在灯板1015上的多个发光二极管。
例如，如图1所示，在从显示区域到非显示区域的方向A-A’上，灯板1015上设置有至少两个发光二极管，在实际产品中，是多个发光二极管围绕显示面板102设置成一整圈。
例如，非显示区域为显示面板的边框区域，在从显示区域到非显示区域的方向A-A’上，边框区域的尺寸小于第一承载部的宽度，且第一承载部的宽度为边框区域的尺寸的一半或者1/3。
例如，图2为本公开至少一实施例提供的再一种显示模组的截面结构示意图，图2与图1中所示显示模组10的不同之处在于，在图2中，该显示模组10包括设置在第一承载部1013a上的导光板1016，该第二光源1014包括设置在第一承载部1013a的侧壁上的灯条，即，该第二光源1014并不是图1中灯板上设置多个发光二极管的结构。例如，在图2中，该灯条围绕显示面板102设置成一整圈。
例如，该导光板1016为网点式导光板，可以对从灯条发射的光线进行均匀地出射。
例如，如图1和图2所示，在该显示模组10中，第二承载部1013b的宽度小于第一承载部1013a的宽度，这样可以保证，背光模组101与显示面板102连接处的面积足够小，设置在边缘区域的第二光源1014发射的光线照射的区域足够大，从而可以实现对边缘位置亮度的提升。
例如，如图1和图2所示，该第二承载部1013b的宽度为第一承载部1013a的宽度的1％～10％。例如，第二承载部1013b的宽度为第一承载部1013a的宽度的1％、2％、4％、6％、8％或者10％。
需要说明的是，第一承载部1013a的宽度和第二承载部1013b的宽度分别为图1或者图2中从显示区域到非显示区域的方向A-A’的方向上的宽度。
例如，如图1和图2所示，该中框1013包括向第一光源1012凸起的弧形部1013c，在该弧形部1013c和背板1011的侧板1011b以及底板1011a之间的容纳空间D，以及第一支撑部1013d，该第一支撑部1013d设置在该容纳空间D中，且该第一支撑部1013d呈“L”型，第一支撑部1013d的第一端和第一承载部1013a的靠近底板1011a的表面连接，该第一支撑部1013d的第二端和弧形部1013c的靠近侧板1011b的表面连接。需要说明的是，该第一支撑部1013d还可以为锯齿状等其他的形状，本公开的实施例对此不作限制。
例如，如图1和图2所示，该第一支撑部1013d和侧板1011b之间具有间隙117。
例如，如图1和图2所示，该第一支撑部1013d将容纳空间D划分为第一子容纳空间D1和第二子容纳空间D2，且第一子容纳空间D1的容积小于第二子容纳空间D2的容积。
例如，图3为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图3所示，该第一子容纳空间D1中设置有信号线104、连接器105和驱动板106，该信号线104的第一端与第二光源1014电连接，且该信号线104的第二端通过连接器105与驱动板106电连接，该驱动板106配置为向第二光源1014提供开启电压。
例如，如图3所示，该显示模组10还包括设置在侧板1011b的远离第二子容纳空间D2一侧的柔性电路板107、支撑泡棉108和柔性电路保护板109，该柔性电路板107和显示面板102连接，且该柔性电路板107配置为驱动显示面板102进行显示。
例如，如图3所示，第一光源1012的发光高度为OD1，OD1的取值范围为25mm～35mm，例如，为25mm、28mm、30mm、32mm或者35mm；第二光源1014的发光高度为OD2，OD2为5mm～10mm，例如，该第二光源1014的发光高度OD2的取值可以为5mm、6mm、8mm或者10mm。B空间 高度为中框1013的一部分和背板1011的一部分以及柔性电路保护板109的锁附固定区域，例如，B的范围为6mm～10mm，例如，B的范围为6mm、7mm、8mm、9mm或者10mm，A空间高度为柔性电路板107放置的空间区域，B的范围为15mm、16mm、17mm、18mm、19mm或者20mm。
例如，如图1、图2和图3所示，该中框1013还包括第二支撑部1013e，该第二支撑部1013e呈长条形，该第二支撑部1013e的第一端连接至第一承载部1013a，该第二支撑部1013e的侧壁与侧板1011b的侧壁贴合，以对侧板1011b进行支撑。
例如，如图1、图2和图3所示，该第二支撑部1013e的第二端是处于悬空状态的。
例如，如图1、图2和图3所示，该中框1013的与背板1011的底板1011a接触的表面平行于底板1011a的主表面，从而使得该中框1013与底板1011a能够完全贴合，进而使得中框1013可以平稳地固定在底板1011a。
例如，如图1、图2和图3所示，该显示面板102包括液晶盒1021和设置在液晶盒1021的靠近背光模组101一侧的扩散板1022(例如，玻璃扩散板)，该第二承载部1013b与玻璃扩散板通过粘合胶103贴合。例如，该粘合胶1023可以为紫外光固化胶、热熔胶或者紫外光固化胶和热熔胶结合形成的胶水等。第一光源1012和第二光源1014发出的光线可以通过该粘合胶1023传输到液晶盒1021上。
例如，图4为本公开至少一实施例提供的一种液晶盒的截面结构示意图，该液晶盒1021包括彼此面对并且分隔开的第一基板1021a和第二基板1021b以及在第一基板1021a和第二基板1021b之间的液晶层1021c。虽然未示出，但在第一基板(例如，阵列基板)1021a的内表面上形成有多条栅线和多条数据线。该多条栅线和多条数据线彼此交叉以限定像素区域，并且薄膜晶体管(TFT)与栅线和数据线均连接。每个像素区域中的透明像素电极与薄膜晶体管的源极或者漏极电连接。另外，覆盖栅线、数据线和薄膜晶体管的黑矩阵形成在第二基板(例如，彩膜基板)1021b的内表面上，并且包括红色滤、绿色滤色器和蓝色滤色器的彩膜层形成在黑矩阵上，例如，透明公共电极形成在彩膜层上。
如图4所示，在第一基板1021a和液晶层1021c之间形成有第一取向层(图4中未示出)，并且在第二基板1021b和液晶层1021c之间形成有第二 取向层(图4中未示出)。另外，在第一基板1021a和第二基板1021b之间的边缘部分中形成有密封图案1021d，该密封图案1021d例如为封框胶图案，以防液晶层泄漏，例如，该密封图案1021d不限于热固化型封框胶或者紫外光固化型封框胶。该密封图案1021d与第一基板1021a、第二基板1021b之间形成容置空间，液晶层1021c即设置在该容置空间中。
例如，在第一基板1021a和第二基板1021b的外表面上还可以分别形成有第一偏振片(图4中未示出)和第二偏振片(图4中未示出)，本公开的实施例对此不作限定。
例如，该第一基板1021a和第二基板1021b的材质可以包括玻璃、塑料或者其它透光的材质，且第一基板1021a和第二基板1021b的材质可为相同或者不相同。
需要说明的是，在图4所示的结构中，是以液晶层1021c作为显示介质形成的液晶显示面板，在本公开的实施例中，显示介质也可以为有机电致发光材料或者电泳材料，本公开的实施例对此不作限定。
例如，该扩散板1022还可以为玻璃扩散板之外的其他类型的扩散板，例如，图5为本公开至少一实施例提供的一种扩散板的截面结构示意图，如图5所示，该扩散板包括：扩散片1022a、棱镜片1022b和增光片1022c或者其他光学复合膜材。该扩散片1022a、棱镜片1022b和增光片1022c可以依次层叠形成于透明基板上。该透明基板需要具备一定的强度、抗热胀冷缩的性能。例如，该透明基板可以为玻璃基板。应该理解的是，在其他示例性实施例中，该扩散板1022还可以为其他的结构，例如，该扩散片1022a、棱镜片1022b和增光片1022c可以以其他的顺序依次堆叠，或者，在一个示例中，该扩散板1022仅包括扩散片1022a和棱镜片1022b等，这些都属于本公开的实施例保护的范围。
例如，如图1、图2和图3所示，该显示模组10还包括设置在底板1011a上的反射膜112，且该反射膜112至少部分设置在底板1011a和中框1013的底表面之间，且该反射膜112和底板1011a以及中框1013的底表面均接触。
例如，如图1、图2和图3所示，该中框1013的靠近第一光源1012的一侧具有向第一光源1012的一侧凸起的弧形表面，该弧形表面上设置有光学膜层113，该光学膜层113配置为将第一光源1012发射的照射到该光学膜层1012上的光线导向到显示面板102。例如，该向第一光源1012的一侧凸 起的弧形表面更有利于光线的传导。
需要说明的是，由于光学膜层113具有一定的侧向导光性，当光学膜层113与中框1013的弧形表面的外轮廓尺寸不完全匹配，具有较小的误差时，即该光学膜层113不是完全贴附于中框1013的弧形表面上时，该光学膜层113依然可以实现导光的作用。
例如，在中框1013的弧形表面上设置光学膜层113可以避免该中框1013的弧形表面吸收第一光源发射的光线，从而避免显示模组的边缘出现发暗不良的现象。在中框1013的弧形表面上设置光学膜层113的一种具体实施方式可以是，在中框1013的弧形表面上涂覆一层白漆。在中框1013的弧形表面上设置光学膜层113还可以有更多的实现方式，例如，在中框1013的弧形表面上蒸镀反射金属层，这些都属于本公开的实施例保护的范围。
例如，该光学膜层113可以通过透明粘结层(图1、图2和图3中均未示出)与显示面板102连接。透明粘结层具有较强的透光性，光学膜层113出光侧的光线可以通过透明粘结层传输到显示面板102，从而可以避免显示面板102的边框发暗导致的显示效果不佳的问题。例如，该透明粘结层可以为紫外光固化胶、热熔胶或者是紫外光固化胶和热熔胶结合形成的胶水等。
例如，如图1、图2和图3所示，该显示模组10还包括遮光胶带114，该遮光胶带114与显示面板102的侧表面、第一承载部1013a的侧表面和底板1011a的远离显示面板102的表面均连接。例如，在显示模组10的整体结构中，该显示模组10包括设置在背光模组101的各个边缘的保护壳，保护壳可以包括胶框部(图中未示出)和胶带部(即遮光胶带114)。胶框部连接于背板1011的底板1011a上，遮光胶带114连接于中框1013与胶框部之间，且覆盖显示面板102的远离背光模组101一侧的部分表面，以及背板1011的一部分表面。此外，该显示模组10的侧面均可以缠绕密封胶带以实现对显示模组10的密封。
例如，该遮光胶带114是整体密封的，以防止漏光。
例如，该遮光胶带114不仅可以保护与之连接的显示面板102、第一承载部1013a和底板1011a，且还能在后续形成拼接屏时使得各个显示模组能够实现拼接。
例如，如图1、图2和图3所示，该显示模组10还包括设置在遮光胶带114和第二光源1014之间的反射层115，且该反射层115与遮光胶带114贴 合。该反射层115可以将第二光源1014发射的光线反射到边缘区域，从而使得从第二光源1014发射的光线更多地射向显示面板102，从而提高对第二光源1014发射的光线的利用率。
例如，如图1、图2和图3所示，该显示模组10还包括设置在显示面板102的远离背光模组101一侧的玻璃板116，该玻璃板116的边缘具有弧形部分以形成2.5D玻璃，该2.5D玻璃对背光源发射的光线进行折射，以实现放大图像的效果，可以在显示模组中采用该2.5D玻璃进行无缝显示。
例如，图6为本公开至少一实施例提供的又一种显示模组的截面结构示意图，图6所示显示模组的截面结构是和图3所示显示模组的截面结构对称设置的，如图6所示，在该第一子容纳空间D1中设置有信号线104、连接器105和驱动板106，该信号线104的第一端与第二光源1014电连接，且该信号线104的第二端通过连接器105与驱动板106电连接，该驱动板106配置为向第二光源1014提供开启电压。与图3的不同之处在于，该显示模组10的第二子容纳空间D2中没有设置柔性电路板、支撑泡棉和柔性电路保护板。
例如，结合图1和图6，该第一承载部1013a的宽度W为10mm～20mm，例如，该第一承载部1013a的宽度W为10mm、12mm、14mm、16mm、18mm或者20mm，以保证对显示面板的支撑强度的同时，节省第一承载部1013a上的第二光源的制作费用。
例如，图6中的其他结构可以参见上述图3中的相关描述，在此不再赘述。
例如，图7为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图7所示，该显示模组40包括：背光模组401和显示面板402，该背光模组401包括背板4011、第一光源4012和中框4013。该背板4011包括底板4011a，该第一光源4012设置在底板4011a上，该中框4013设置在底板4011a与显示面板402之间，该中框4013的靠近显示面板402的一侧具有第一承载部4013a和第二承载部4013b，该第一承载部4013a在中框4013的显示区域，且第一承载部4013a上设置有第二光源4014，该第二承载部4013b在第一承载部4013a的靠近显示面板402的周边区域的一侧，且第二承载部4013b与显示面板402的对应于边缘的位置连接，将第二承载部4013b的宽度设置的很窄，在显示区域设置至少两个第二光源4014，可以改善边缘像素 画面发暗的问题。
例如，如图7所示，该中框4013包括与第一承载部4013a的端部连接的弧形部404，该弧形部404向靠近第一承载部4013a的一侧凸起，且第二承载部4013b设置在弧形部404一侧的端部，在第一承载部4013a和弧形部404之间设置有第一支撑部405，第一支撑部405的第一端和第一承载部4013a的表面连接，第一支撑部405的第二端和弧形部404的表面连接以形成第一子容纳空间406，该第一子容纳空间406中可以放置电路板等。
例如，如图7所示，该第一支撑部405为具有拐角的形状，这样可以实现该第一支撑部405对第一承载部4013a和弧形部404进行支撑。
例如，如图7所示，在第一支撑部405的靠近第一光源1012的表面设置有光学膜层413，该光学膜层413配置为将第一光源4012发射的照射到该光学膜层4012上的光线导向到显示面板402。例如，该向第一光源4012的一侧凸起的弧形表面更有利于光线的传导。
例如，在第一支撑部405的靠近第一光源1012的表面设置光学膜层413可以避免该第一支撑部405吸收第一光源1012发射的光线，从而避免显示模组40的边缘出现发暗不良的现象。在第一支撑部405的靠近第一光源1012的表面设置光学膜层413的一种具体实施方式可以是，在第一支撑部405的靠近第一光源1012的表面涂覆一层白漆。在第一支撑部405的靠近第一光源1012的表面设置光学膜层413还可以有更多的实现方式，例如，在第一支撑部405的靠近第一光源1012的表面蒸镀反射金属层，这些都属于本公开的实施例保护的范围。
例如，如图7所示，该显示模组40还包括设置在显示面板402的远离背光模组401一侧的玻璃板416，该玻璃板416的边缘具有弧形部分以形成2.5D玻璃，该2.5D玻璃对背光源发射的光线进行折射，以实现放大图像的效果，可以在显示模组中采用该2.5D玻璃进行无缝显示。
例如，该第一光源4012和第二光源4014的相关特征可以参见上述中的相关描述，在此不再赘述。
例如，第二承载部4013b的宽度小于第一承载部4013a的宽度。例如，如图7所示，该第二承载部4013b的宽度为第一承载部4013a的宽度的1％～10％。例如，第二承载部4013b的宽度为第一承载部4013a的宽度的1％、2％、4％、6％、8％或者10％。
需要说明的是，第一承载部4013a的宽度和第二承载部4013b的宽度为图7中从显示区域到非显示区域的方向A-A’的方向上第一承载部4013a的宽度和第二承载部4013b的宽度。
例如，图8为本公开至少一实施例提供的一种显示装置的平面结构示意图，如图8所示，该显示装置20包括多个上述任一实施例提供的显示模组10或者40形成的拼接屏。例如，尽管图8中示出的是该显示装置20包括6个显示模组10拼接形成的拼接屏，但是本公开的实施例不限于此。该显示装置还可以包括更多个显示模组10，例如，2个、4个、9个等。多个显示模组10彼此拼接设置，且在任意相邻的两个显示模组10之间形成拼接缝a。在一些示例中，该显示模组10可以为液晶显示模组、有机发光二极管(OLED)显示模组或者电泳显示模组。至少有第二光源1014设置于邻近拼接缝a处。邻近拼接缝处是指距离拼接缝a大约1cm的长度之内的范围，其可以根据显示装置的尺寸确定。结合图8和图3，该第二光源1014可以为发光二极管(LED)、或者由多个发光二极管所组成的发光条(Light bar)、或者其它能够发光的组件，例如，有机发光二极管(OLED)。在本公开的实施例中，第二光源1014以直线排列的发光条为例，且各个显示模组10在邻近拼接缝a处都分别设置有第二光源1014。
例如，该显示装置10包括上述任一显示模组，本公开的实施例中的显示装置可以为：显示器、电子纸、手机、平板电脑、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
例如，图9为本公开至少一实施例提供的显示装置进行显示的亮度曲线图，如图9所示，横坐标为到显示装置边缘的距离，纵坐标为对应不同横坐标时，显示装置的边缘的亮度，从图9中可以看出，距离显示装置的边缘的距离为4.5mm时，显示装置的亮度最大为167nit。且通过边缘亮度曲线测试可以得出，本公开的实施例提供的显示装置的边缘亮度的均一度可以达到95％。
本公开至少一实施例还提供一种中框，该中框包括：第一承载部和与第一承载部的端部连接的弧形部，该弧形部向远离第一承载部的一侧凸起，且弧形部一侧的端部设置有第二承载部，在第一承载部和弧形部之间设置有第一支撑部，第一支撑部的第一端和第一承载部的与承载面相对的表面连接，第一支撑部的第二端和弧形部的表面连接以形成第一子容纳空间，该中框的 结构简单、且成本较低，将该中框用于显示模组可以避免暗框不良的现象。
例如，图10为本公开至少一实施例提供的一种中框的截面结构示意图，如图10所示，该中框30包括：第一承载部301和与第一承载部301的端部连接的弧形部302，该弧形部302向远离第一承载部301的一侧凸起，且弧形部302一侧的端部设置有第二承载部303，在第一承载部301和弧形部302之间设置有第一支撑部304，第一支撑部304的第一端和第一承载部301的与承载面相对的表面连接，第一支撑部304的第二端和弧形部302的表面连接以形成第一子容纳空间305，该第一支撑部304可以对第一承载部301和弧形部302进行支撑。
需要说明的是，该第一承载部301的承载面是指第一承载部301的被用作后续承载光源的表面，或者是更靠近显示面板的表面。
例如，图10所示中框30的结构简单、且生产成本较低，将该中框30用于显示模组中时可以避免暗框不良的现象发生。
例如，如图10所示，该第一支撑部304呈“L”型，这样可以实现该第一支撑部304对第一承载部301和弧形部302进行支撑，需要说明的是，该第一支撑部304还可以为锯齿状等其他的形状，本公开的实施例对此不作限制。
例如，如图10所示，在该第一子容纳空间305的远离弧形部302的一侧设置有第二支撑部306，且该第二支撑部306呈长条形，该第二支撑部306的第一端与第一承载部301连接。
例如，如图10所示，该第二支撑部306的第二端是处于悬空状态的。
例如，该中框30中的其他结构可以参见上述中关于显示模组的相关描述，在此不再赘述。
例如，图11为本公开至少一实施例提供的再一种中框的截面结构示意图，如图11所示，该中框50包括第一承载部501和与第一承载部501的端部连接的弧形部502，该弧形部502向靠近第一承载部501的一侧凸起，且弧形部502一侧的端部设置有第二承载部503，在第一承载部501和弧形部502之间设置有第一支撑部504，第一支撑部504的第一端和第一承载部501的与承载面相对的表面连接，第一支撑部504的第二端和弧形部502的表面连接以形成第一子容纳空间505。
例如，如图11所示，该第一支撑部504为具有拐角的形状，这样 可以实现该第一支撑部504对第一承载部501和弧形部502进行支撑。
例如，如图11所示，该第二承载部503的宽度小于第一承载部501的宽度。该第二承载部503的宽度为第一承载部501的宽度的1％～10％。例如，第二承载部503的宽度为第一承载部501的宽度的1％、2％、4％、6％、8％或者10％。
在整体的结构中，该中框50为一整圈设置，该第一子容纳空间505也对应形成中空的直筒状。
本公开至少一实施例提供的显示模组和中框，具有以下至少一项有益技术效果：
(1)在本公开至少一实施例提供的显示模组中，通过在中框的边缘处设置第一承载部，在第一承载部上设置第二光源，将第二承载部与显示面板的对应于显示区域的位置连接，以解决窄边框拼接屏因贴合胶透过率差和组装工艺误差导致的边缘像素画面发暗的问题，从而可以提高显示模组边缘像素的亮度。
(2)在本公开至少一实施例提供的显示模组中，在显示面板的远离背光模组的一侧设置有玻璃板，该玻璃板的边缘具有弧形部分以形成2.5D玻璃，该2.5D玻璃对背光源发射的光线进行折射，以实现放大图像的效果，可以在显示模组中采用该2.5D玻璃进行无缝显示。
有以下几点需要说明：
(1)本公开实施例附图只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)为了清晰起见，在用于描述本公开的实施例的附图中，层或区域的厚度被放大或缩小，即这些附图并非按照实际的比例绘制。
(3)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，本公开的保护范围应以所述权利要求的保护范围为准。
