具体实施方式
这里将详细地对示例性实施方式进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施方式中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置的例子。
在本公开使用的术语是仅仅出于描述特定实施方式的目的，而非旨在限制本公开。除非另作定义，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。本公开说明书以及权利要求书中使用的“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，“一个”或者“一” 等类似词语也不表示数量限制，而是表示存在至少一个。“多个”或者“若干”表示两个及两个以上。除非另行指出，“前部”、“后部”、“下部”和/或“上部”等类似词语只是为了便于说明，而并非限于一个位置或者一种空间定向。“包括”或者“包含”等类似词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并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，而且可以包括电性的连接，不管是直接的还是间接的。在本公开说明书和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
相关技术中，如图1所示，显示装置包括背板1、中框15、光学膜层6以及显示面板7，光学膜层6支撑于中框15上，背板1的底壁101上设有光源3，为了避免背光模组的侧部漏光，需要设置中框15为非透明结构，然而，这导致光学膜层6支撑于中框15的区域无法透光，使得显示面板7对应于该区域的部分发暗，产生“暗框”问题，降低了显示效果。如图2所示，拼接显示装置包括多个显示面板7，相邻显示面板7之间存在拼缝13，为了弱化拼缝13，实现视觉无边框的效果，会利用带有圆弧面的盖板14，使显示面板7的边缘射出的光线在经过盖板14的圆弧面折射后进入人眼，从而弱化拼缝13。由于图1中的光学膜层6支撑于中框15的区域无法透光，使得显示面板7对应于该区域的部分发暗，从而使得由图1所示的显示装置拼接而成的拼接显示装置无法弱化拼缝13，无法实现视觉无边框的效果。
本公开实施方式提供一种背光模组，用于显示面板。如图3和图4所示，该背光模组可以包括背板1、光源3、光学膜层6以及中框，其中：
该背板1包括底壁101。该光源3设于底壁101上。该光学膜层6与底壁101相对设置，并位于光源3的出光侧。该中框包括第一框体4和第二框 体5。该第一框体4围绕底壁101的四周设置，第二框体5设于第一框体4的内侧面，第二框体5为透明结构。该光学膜层6支撑于第二框体5远离底壁101的一端。
本公开的背光模组，光源3设于底壁101上，第一框体4围绕底壁101的四周设置，第二框体5设于第一框体4的内侧面，第二框体5为透明结构，光学膜层6支撑于第二框体5远离底壁101的一端，如此设置，可以使得光源3发出的光线穿过第二框体5并到达光学膜层6支撑于第二框体5的区域，防止显示面板7对应于该区域的部分发暗，提高了显示效果；同时，由具有该背光模组的显示装置形成拼接显示装置后，能够实现视觉无边框的效果。
下面对本公开实施方式的背光模组的各部分进行详细说明：
该背板1可以包括底壁101，当然，也可以包括设于底壁101的侧壁102。该底壁101可以与上述的显示面板7相对设置。该侧壁102连接于底壁101面向显示面板7的一侧。该侧壁102可以与底壁101垂直，但本公开对此不做特殊限定。该光源3设于底壁101面向显示面板7的一侧。该光源3的数量可以为多个，且多个光源3可以阵列分布，但本公开实施方式不限于此。本公开实施方式的背光模组还可以包括反射膜2。该反射膜2可以设于底壁101面向显示面板7的表面，上述的光源3可以设于反射膜2背向底壁101的一侧。
该中框可以包括第一框体4。该第一框体4可以连接于背板1的底壁101，例如，第一框体4与背板1的底壁101螺纹连接，再例如，第一框体4卡合于背板1的底壁101。该第一框体4可以围绕背板1的底壁101的四周设置，也就是说，第一框体4呈环状结构。此外，该背板1的侧壁102可以围绕第一框体4，上述的光源3也位于第一框体4所围绕的区域内。该第一框体4可以为非透明结构，可以防止光源3发出的光线穿过第一框体4。具体地，该第一框体4的材料可以为塑胶，但不限于此，还可以为铝材质等。
如图3-图5所示，该第一框体4的内侧面可以包括第一斜面401。其中，该第一框体4的内侧面为第一框体4面向上述光源3的侧面。该第一斜面401与背板1的底壁101的夹角可以为钝角。在本公开其它实施方式中，该第一斜面401与背板1的底壁101的夹角也可以为直角或锐角。此外，如图9和图10所示，该第一斜面401可以设有凹陷部404。该凹陷部404的数量可以为一个、两个、三个、四个或更多个。该凹陷部404的下部的横截面积可以大于凹陷部404的上部的横截面积。
如图3和图4所示，该第一框体4的内侧面还可以包括第二斜面402。在背板1的底壁101的厚度方向上，该第二斜面402可以位于第一斜面401与背板1的底壁101之间。在与背板1的底壁101平行的方向上，该第一斜面401可以位于第二斜面402远离光源3的一侧。该第二斜面402与背板1的底壁101的夹角γ可以为钝角，当然，该第二斜面402与背板1的底壁101的夹角γ也可以为直角或锐角。以第一斜面401与背板1的底壁101的夹角为钝角且第二斜面402与背板1的底壁101的夹角为钝角为例，第一斜面401与背板1的底壁101的夹角可以大于第二斜面402与背板1的底壁101的夹角，但本公开不限于此，第一斜面401与背板1的底壁101的夹角也可以小于或等于第二斜面402与背板1的底壁101的夹角。如图5所示，该第一框体4的内侧面还可以包括连接面403。该连接面403可以连接于第一斜面401与第二斜面402之间。该连接面403可以为平面，该连接面403可以与背板1的底壁101平行或大致平行。在本公开其它实施方式中，该连接面403也可以为斜面或曲面。
举例而言，在背板1的底壁101的厚度方向上，该第一框体4可以包括第一框段和第二框段，该第二框段位于第一框段与背板1的底壁101之间；该第一框段呈环状结构，该第二框段呈环状结构，上述的第一斜面401为第一框段的内侧面，上述的第二斜面402为第二框段的内侧面。
此外，如图4和图6所示，该第一框体4远离背板1的底壁101的一 端设有支撑部8。该支撑部8用于支撑显示面板7。以第一框体4呈环状结构为例，该支撑部8也可以呈环状结构。该支撑部8可以包括面向光源3的第一表面801以及背向光源3的第二表面802。该第一表面801可以与上述的第一斜面401连接。该第二表面802可以竖直设置，即第二表面802可以垂直于背板1的底壁101。该第一表面801靠近显示面板7的一侧可以朝第二表面802弯折，也就是说，第一表面801与第二表面802之间的距离沿着靠近显示面板7的方向逐渐减小，如此设置，可以增大显示面板7的显示区与支撑部8的距离，防止边缘像素被遮挡。其中，该第一表面801的弯折部分与非弯折部分可以平滑过渡连接。此外，该第一表面801靠近显示面板7的侧边与第二表面802靠近显示面板7的侧边之间的距离L2可以为0.2mm-0.5mm。
如图3、图4以及图7所示，该中框还可以包括第二框体5。该第二框体5可以设于第一框体4的内侧面。以第一框体4的内侧面包括第一斜面401为例，该第二框体5可以设于第一斜面401，也就是说第二框体5设于第一框段的内侧面。该第二框体5可以粘结于第一斜面401，例如，第二框体5通过双面胶粘结于第一斜面401。以第一斜面401设有凹陷部404为例，该第二框体5可以设有突出部504，该突出部504可以卡合于第一斜面401上的凹陷部404。以凹陷部404的数量为多个为例，该突出部504的数量也可以为多个，且多个突出部504可以一一对应地卡合于多个凹陷部404。此外，该第二框体5也可以与上述的连接面403配合，如此设置，可以使第二框体5更加牢固地设于第一斜面401上。该第二框体5也可以呈环状结构，该第二框体5在背板1的底壁101上的正投影可以围绕上述的光源3。该第二框体5可以为透明结构，其材料可以为透明塑胶材料，例如PMMA、PC等。
此外，如图4和图7所示，该第二框体5背向第一斜面401的一侧包括第三斜面501和第四斜面502。该第三斜面501可以连接于上述的第二斜面402。进一步地，该第三斜面501可以与第二斜面402共面。该第三斜面501与背板1的底壁101的夹角可以与第四斜面502与背板1的底壁101的夹角 不同，且第三斜面501可以与第四斜面502平滑过渡连接。该第四斜面502可以与上述的第一斜面401平行，当然，也可以不平行。该第四斜面502与背板1的底壁101的夹角为钝角。
如图4和图7所示，该第二框体5远离背板1的底壁101的一端设有支撑面503。该支撑面503可以连接于上述的第四斜面502与第一斜面401之间。该支撑面503可以与背板1的底壁101平行，但本公开不限于此。以第二框体5呈环状结构为例，该支撑面503可以呈环形。该支撑面503靠近光源3的边界与支撑面503远离光源3的边界之间的距离L1可以为2mm-3.5mm，例如2mm、2.5mm、3mm、3.5mm等。以支撑面503呈环形为例，该支撑面503靠近光源3的边界即为支撑面503的内边界，该支撑面503远离光源3的边界即为支撑面503的外边界。
在本公开另一实施方式中，如图7和图8所示，该支撑面503上可以设有凸起12。该凸起12具有面向光源3的第一侧面1201以及背向光源3的第二侧面1202。该第一侧面1201与背板1的底壁101的夹角α可以为钝角，例如120°-150°，更具体地，120°、130°、140°、150°等。该第二侧面1202与背板1的底壁101的夹角β可以为锐角，例如30°-60°，更具体地，30°、40°、50°、60°等。该第一侧面1201可以与第二侧面1202相连接。该凸起12可以呈条形，且沿着光源3的外周延伸，上述的第一侧面1201和第二侧面1202可以为凸起12的宽度方向上的两个侧面。此外，以支撑面503呈环形为例，该凸起12可以为环形凸起，且环形凸起在背板1的底壁101上的正投影可以围绕上述的光源3。该凸起12的高度L4可以为50μm-200μm，例如50μm、100μm、150μm、200μm等。该凸起12的宽度L3可以为50μm-400μm，例如50μm、180μm、250μm、400μm、500μm等。此外，该凸起12的数量可以为多个，以凸起12为环形凸起为例，多个凸起12沿着远离光源3的方向依次设置。如图所示，经过多次反射的光线穿过凸起12的第一侧面1201时，光线会发射折射，由于第一侧面1201与背板1的底壁101的夹角为钝角， 可以使得折射光线朝背光模组的边缘出射，进一步提高了边缘亮度。此外，该凸起12的材料可以与第二框体5的材料相同，但本公开对此不做特殊限定。该凸起12可以与第二框体5为一体式结构，但本公开不限于此。
如图3所示，该光学膜层6支撑于第二框体5远离底壁101的一端。其中，该光学膜层6可以支撑于第二框体5的支撑面503，如此设置，光源3发出的光线在穿过第二框体5后可以直达光学膜层6支撑于第二框体5的区域。以第二框体5为环形结构为例，该光学膜层6的边缘区域可以支撑于第二框体5远离底壁101的一端。以第二框体5的支撑面503设有凸起12为例，该光学膜层6可以设于多个凸起12上。该背光模组还可以包括前框11。该前框11可以设于中框的外侧。进一步地，该前框11可以设于背板1的侧壁102外侧，并可以通过螺纹件10连接于背板1的侧壁102。该光学膜层6可以包括扩散板。该扩散板可以与显示面板7相对设置。该扩散板的材料可以为聚苯乙烯(PS)，但本公开对此不做限定。该光学膜层6还可以包括扩散片。该扩散片可以位于扩散板与显示面板7之间。
本公开实施方式还提供一种显示装置。该显示装置可以包括显示面板7以及上述任一实施方式所述的背光模组。该显示面板7可以设于光学膜层6背向背板1的底壁101的一侧，且支撑于上述的支撑部8，上述的前框11可以通过粘结胶9粘结于显示面板7。该显示面板7可以为液晶显示面板，其可以包括：对盒设置的阵列基板和彩膜基板，以及位于该阵列基板和彩膜基板之间的液晶层。如图11所示，X1为本公开的显示装置的亮度曲线，X2为采用图1所示结构的显示装置的亮度曲线，横坐标代表显示面板7的显示区中的一个位置点到显示区边缘的距离，纵坐标代表该位置点处的亮度和画面中心区域的相对亮度比例，可以看出，应用本公开的技术方案，显示装置的周边亮度与中心区域亮度差异减小，亮度提升效果明显。由于本公开实施方式的显示装置所包括的背光模组与上述背光模组的实施方式中的背光模组相同，因此，其具有相同的有益效果，本公开在此不再赘述。
本公开实施方式还提供一种拼接显示装置。该拼接显示装置可以由多个上述实施方式中的显示装置拼接而成。由于本公开实施方式的拼接显示装置所包括的显示装置与上述显示装置的实施方式中的显示装置相同，因此，其具有相同的有益效果，本公开在此不再赘述。
以上所述仅是本公开的较佳实施方式而已，并非对本公开做任何形式上的限制，虽然本公开已以较佳实施方式揭露如上，然而并非用以限定本公开，任何熟悉本专业的技术人员，在不脱离本公开技术方案的范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本公开技术方案的内容，依据本公开的技术实质对以上实施方式所作的任何简单修改、等同变化与修饰，均仍属于本公开技术方案的范围内。
