框架1，背光源2以及保护膜3；其中：
框架1由背板11以及设置于背板11周边的侧壁12构成，背光源2容置于由背板11以及侧壁12构成的空间内，其中，背光源2的出光面(图1箭头所示为出光方向)远离背板11；
保护膜3覆盖背光源2的出光面，并且沿着框架1的至少两个相对的侧壁12延伸至背板11远离背光源2的外侧，并与背板远离背光源的外侧固定连接。
本公开的实施例所提供的背光模组，去掉了现有结构中所设置的胶框，背光源2(包括导光板21以及其他膜材)直接与框架1接触，从而可缩小背光模组的尺寸，实现显示产品的窄边框化。
同时，该背光模组中设置有保护膜3。该保护膜3通过包裹的方式，将背光源2包覆在框架1内，从而实现背光源2的固定，避免了相关技术中因去掉胶框而产生的背光源无法固定的问题。
本公开的实施例中的保护膜3具体可为透光材质，从而可在不影响背光源2光学效果的前提下，起到固定背光源2的作用。
为了实现与框架1固定连接，保护膜3本身可具有粘黏的特性。另外， 也可以通过在保护膜3与框架1的背板11接触的位置处涂覆具有粘黏特性的物质的方式，以实现保护膜3与背板11的外侧固定连接。
在具体实现时，保护膜3可沿着框架1的长度方向上的两个侧壁12延伸至背板11的外侧，并与背板11的外侧固定连接，从而可在不增加背光模组宽度的情况下，起到固定背光源2的作用。
可选地，保护膜3还与框架长度方向上的两个侧壁12的外侧固定连接。
在另一具体实施例中，保护膜3也可沿着框架1的四个侧壁12延伸至背板11的外侧，并与背板11的外侧固定连接。
可选地，保护膜3还与框架的四个侧壁12的外侧固定连接。
本公开的实施例所涉及的框架1的材质，具体可为不锈钢、铝合金等，为了减轻框架1以及背光模组的重量，框架1也可以采用碳纤维等材质。
本公开的实施例所涉及的背板11，具体可具有例如长方形等的几何形状。以长方形为例，可在背板11的四个侧边位置处均设置侧壁12，以形成容置背光源2的空间。另外，为了减小背光模组的重量以及宽度，也可只在背板11的长度方向的两侧设置侧壁12，以形成容置背光源2的空间。
在具体实施例中，侧壁12相对于背板11的高度可与背光源2的厚度相同。这样，如图2所示，在保护膜3包裹背光源2之后，可直接通过粘黏等方式，将显示面板(panel)4贴附在保护膜3远离背光源2的一侧，显示面板4的周边不需要框架固定，因此显示面板4的边框即为背光模组的边框，从而实现了显示产品窄边框的效果。
本公开实施例中，背光源2具体可以包括导光板21。
如图3所示，该导光板21可设置自固定结构22，该自固定结构22用于使背光源2固定于由背板11以及侧壁12构成的空间内。
通过设置自固定结构22，可进一步确保将背光源2固定于框架1内。
在具体实施例中，该自固定结构22可设置于导光板21的长度方向上的两侧。该自固定结构22可为凸耳，从而可在减小导光板21的材料使用量的情况下，通过抵触框架1侧壁12的方式(框架1的侧壁12上不设置固定孔，以避免框架1出现漏光的情况)，使背光源2固定于由背板11以及侧壁12构成的空间内。
如图3所示，本公开的实施例中的导光板21中，还可设置发光二极管(LED)固定位23，用于固定背光源2中所设置的LED24。
该LED固定位23中可设置电路走线等器件，以实现对LED24的控制。该LED固定位23可基于需要设置于导光板21的预设位置处，例如导光板21的长度方向上的一侧。
如图4所示，本公开的实施例所涉及的背光源2中具体还包括以下膜层：
设置于导光板21的第一侧面的第一反射膜25，该第一侧面具体可为导光板21靠近背板11的侧面，即如图4所示的导光板21下侧；
设置于导光板21的第二侧面的扩散膜26，该第二侧面具体可为导光板21远离背板11的侧面，即如图4所示的导光板21上侧；
设置于扩散膜26远离导光板21一侧的第一棱镜膜27；
设置于第一棱镜膜27远离扩散膜26一侧的第二棱镜膜28。
由于第二棱镜膜28位于背光源2的出光面的最外侧，因此，保护膜3可设置于第二棱镜膜28远离第一棱镜膜27的一侧，即图4中第二棱镜膜28的上侧。
本公开的实施例中，为了避免背光源2中，LED 24所在位置处发生漏光现象，因此，如图4所示，背光源2还可以包括：
设置于LED 24远离导光板21一侧的第二反射膜29，其中，第二反射膜29位于LED 24远离第一反射膜25的一侧。
本公开的实施例中，为了避免在背光源2的侧面周边发生漏光的现象，保护膜3与背光源2的侧面周边对应的部分具有遮光功能，从而可避免在背光源2的侧面周边发生漏光的现象。
那么在具体实现时，可在保护膜3制作过程中或者制作之后，通过在保护膜3与背光源2的侧面周边对应的部分进行相应的处理，以使该部分保护膜3具有遮光功能。
本公开实施例还提供了一种显示装置，该显示装置具体可以包括上述本公开的实施例提供的背光模组。
以上所述仅是本公开的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开原理的前提下，还可以作出若干改进和润饰， 这些改进和润饰也应视为本公开的保护范围。
