具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的背板、框架结构、背光模组和显示装置进行详细描述。
图1为相关技术中所涉及显示装置的一种截面示意图，如图1所示，该显示装置包括：框架结构8和显示面板3，框架结构8包括背板1和中框2，背板1包括：底板101(用于承载光源，一般呈平面设置)和侧壁102，中框2包括：主体结构201和承载结构202。其中，承载结构202用于承载并固定显示面板3，具体地，显示面板3包括显示区和围绕显示区的边缘区(边缘区不进行画面显示)，显示面板3的边缘区通过双面胶4固定于承载面上。
随着全面屏技术的发展，显示面板3上的边缘区的宽度越来越窄，若保持承载结构202的宽度不变，则在将显示面板3与承载结构202的承载面进行固定后，承载结构202和双面胶4会侵入至显示面板3的显示区，影响显示效果。若减小承载结构202的宽度以避免承载结构202和双面胶4侵入至显示面板3的显示区，此时承载结构202容易发生应力形变(例如，显示面板3下压承载结构202而导致承载结构202发生向下形变)而导致承载面与显示面板3之间的双面胶4失效，进而导致显示面板3脱离，即承载结构202整体的承载平稳度较低。
为解决相关技术中存在的至少之一的技术问题，本公开提供了相 应的技术方案，下面将结合具体实施例进行详细描述。
图2为本公开所涉及的显示装置的一种结构示意图，图3为图2中A-A'向截面示意图。如图2和图3所示，该显示装置包括：背光模组和显示面板3，背光模组包括框架结构8、光学模组5和光源(未示出)，框架结构8包括背板1和中框2，背板1与中框2装配固定，中框2包括主体结构201和承载结构202，显示面板3固定于承载结构202的承载面上；光线模组包括导光板6和光学膜片7(还可包括扩散板等结构)，光线模组固定于框架结构8内。
在一些实施例中，导光板6的侧面可以为入光面，此时光源为侧入式光源，导光板6的下表面可设置反射膜以提升导光板6上表面的出光量；在另一些实施例中，导光板6的下表面为入光面，此时光源为直下式光源，导光板6的侧面可设置反射膜以提升导光板6上表面的出光量。此两种情况均属于本公开的保护范围。
图4为本公开实施例提供的背板的一种截面示意图。如图2至图4所示，本公开实施例提供了一种背板1，该背板1用于与中框2进行装配形成框架结构8，中框2包括具有承载面的承载结构202，承载面用于承载显示面板3，背板1包括：底板101和由底板101的边缘弯折形成的侧壁102，侧壁102用于与中框2进行装配，底板101上形成有第一支撑结构103，第一支撑结构103用于支撑承载结构202。
在本公开实施例中，通过在底板101上形成第一支撑结构103，第一支撑结构103可在背板1与中框2完成装配后起到对中框2内的承载结构202进行支持的作用，可有效避免承载结构202发生应力形变，从而能提升承载结构202整体的承载平稳度，进而保证显示面板3与承载结构202之间的结合牢固度。
需要说明的是，在本公开实施例中第一支撑结构103支撑承载结构202并不限于第一支撑结构103直接于承载结构202相接触以对承载结构202进行支撑，还可以是第一支撑结构103通过其他结构来与承载结构202相接触以对承载结构202进行支撑，后面将结合具体示例来对承载结构202进行支撑。
在一些实施例中，第一支撑结构103由底板101上的部分区域通过弯折形成，第一支撑结构103复用作加强筋以提升背板1整体的强度和刚性，从而有效防止背板1发生应力形变。
进一步地，第一支撑结构103在垂直于底板101的截面的截面形状呈“几”字形。呈“几”字形的加强筋结构一方面可以提升背板1整体的强度和刚性，另一方面其顶部(远离底板101一侧表面)呈平面有利于提供稳定的支撑。在一些实施例中，第一支撑结构103远离底板101一侧表面为平面且具有预设宽度w1；其中，若宽度w1过大，则背板1整体的强度和刚性会下降；在一些实施例中，宽度w1满足，0＜w1≤2mm。
在一些实施例中，承载结构202背向承载面的一侧设置第二支撑结构203；第一支撑结构103与侧壁102之间限定出容纳槽104，容纳槽104用于容纳并支撑第二支撑结构203；具体情况，后面将结合附图进行详细描述。
在一些实施例中，第一支撑结构103还用于与承载结构202背向承载面的一侧相配合以夹持固定显示面板3所配置的光学模组5，此时第一支撑结构103通过光学模组5来对承载结构202进行支撑；具体情况，后面将结合附图进行详细描述。
本公开实施例所提供的背板1可以为一体式结构，其材料可以为金属材料(例如铝)，具体可通过金属冲压工艺来制备背板1。
图5为本公开实施例提供的框架结构的一种截面示意图。如图5所示，本公开实施例还提供了一种框架结构8，该框架结构8包括背板1和中框2；其中，背板1采用上述实施例所提供的背板1，具体内容可参见前面实施例中的内容，此处不再赘述。
中框2包括：主体结构201和位于主体结构201上的承载结构202。主体结构201用于与背板1中的侧壁102进行装配固定，例如采用卡合方式固定、螺丝固定等，本公开的技术方案对具体的装配方式不作限定。
在一些实施例中，承载结构202上承载面的宽度w2满足0.5mm ≤w2≤6mm。
承载结构202上承载面的宽度可根据显示面板3的边缘区的宽度来设计，一般地，承载面的宽度略小于显示面板3的边缘区的宽度。鉴于常规显示面板3的边缘区的宽度在0.6mm～6mm范围，在一些实施例中，承载结构202上承载面的宽度w2满足0.5mm≤w2≤6mm。
在一些实施例中，承载结构202与主体结构201一体成型。可选地，整个中框2为一体成型结构，中框2的材料包括塑料，具体可通过注塑工艺来制备中框2。
在一些实施例中，在中框2内，承载结构202背向承载面的一侧设置第二支撑结构203；在背板1内，第一支撑结构103与侧壁102之间限定出容纳槽104；其中，容纳槽104用于容纳第二支撑结构203，同时通过对第二支撑结构203的高度进行合理设置使得第二支撑结构203的底部与容纳槽104的底部(底板101)相接触，即容纳槽104的底部能够支撑第二支撑结构203，此时第二支撑结构203也能起到对承载结构202的支撑，从而能够进一步提升承载结构202整体的承载平稳度。
在图5所示情况中，第一支撑结构103与承载结构202直接接触以对承载结构202进行支撑。
图6为本公开实施例提供的框架结构的一种截面示意图。如图6所示，与图5所示情况不同，在图6所示情况中第一支撑结构103的顶部与承载结构202之间存在一定容纳空间9，该容纳空间9用于供第一支撑结构103和承载结构202夹持固定光学模组5，此时第一支撑结构103通过光学模组5来对承载结构202进行支撑。
图7为本公开实施例提供的背光模组的一种截面示意图，图8为本公开实施例提供的背光模组的另一种截面示意图。如图7和图8所示，本公开实施例还提供了一种背光模组，该背光模组包括框架结构8，框架结构8采用上述实施例提供的框架结构8，对于框架结构8的具体描述可参见前面实施例中内容，此处不再赘述。
在一些实施例中，背光模组还包括光学模组5，光学模组5至少 包括导光板6和光学膜片7(还可包括扩散板等结构)，光线模组固定于框架结构8内。
参见图7中所示，在一些实施例中，第一支撑结构103与承载结构202直接接触，光学模组5可固定于背板1上。参见图8中所示，第一支撑结构103的顶部与承载结构202之间存在一定容纳空间，光学模组5位于第一支撑结构103和承载结构202之间，第一支撑结构103与承载结构202背向承载面的一侧相配合以夹持固定光学模组5。
需要说明的是，本公开实施例中的背光模组中还包括光源，光源可以为直下式光源或侧入式光源。
基于同一个发明构思，本公开实施例还提供了一种显示装置，参见图3所示，该显示装置包括背光模组和显示面板3，该背光模组采用上述实施例提供的背光模组，对于背光模组的具体描述可参见前面实施例中内容，此处不再赘述。显示面板3可通过粘连结构(例如双面胶4或固定胶水)固定于承载面上。
需要说明的是，图3所示显示装置内的背光模组为图8中所示的情况仅起到示例性作用，其不会对本公开的技术方案产生限制。在一些实施例中，也可以将图3所示显示装置内的背光模组替换为图7中所示情况，该技术方案也应属于本公开的保护范围。
本公开实施例中的显示装置可以为：液晶显示器、电子纸、手机、平板电脑、电视机、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。
本公开的技术方案通过在底板上形成第一支撑结构，第一支撑结构可在背板与中框完成装配后起到对中框内的承载结构进行支持的作用，可有效避免承载结构发生应力形变，从而能提升承载结构整体的承载平稳度，进而保证显示面板与承载结构之间的结合牢固度。
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。
