 本发明的实施方式
本申请提供一种背光模组和显示装置，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请实施例针对现有背光模组存在灯板间隙处的温度较高，导致显示不均的技术问题，本申请实施例用以缓解上述技术问题。
如图1所示，现有背光设计中，会在背板11上设置多个小块灯板12，以使多个小块灯板拼接形成玻璃灯板，但在拼接过孔中，相邻的小块灯板12之间会存在一定的间隙，包括纵向间隙121和横向间隙122，在间隙中会填充有空气，而空气的导热较差，导致小块灯板的间隙处的温度较高，如图2所示，在采用有限元仿真技术测量背光的温度时，会发现位于灯板间隙处的温度123和加强筋处的温度13大于背板其他区域111的温度，导致间隙处的温度较高，从而导致显示面板出现显示不均的问题，即现有背光模组存在灯板间隙处的温度较高，导致显示不均的技术问题。
需要说明的是，为了清楚的看出各个区域的温度表示，图2中仅表示出一处横向间隙和纵向间隙、一处加强筋和一处其他区域的背板的温度，实际上各个区域的对应温度相同。
如图3所示，本申请实施例提供一种背光模组，该背光模组包括：
背板21；
光源，设置于所述背板21上，所述光源包括拼接的多块灯板22，所述灯板22之间形成有间隙224；
光学膜片24，设置于所述光源远离所述背板21的方向上；
其中，在对应所述灯板22之间的间隙224的区域223，所述背板21在远离灯板22的方向上形成有凹槽211，所述凹槽211形成位于所述背板21远离光源一侧的加强筋213，所述凹槽211内形成有散热结构212。
本申请实施例提供一种背光模组，该背光模组包括背板、光源和光学膜片，所述光源设置于所述背板上，所述光源包括拼接的多块灯板，所述灯板之间形成有间隙，所述光学膜片设置于所述光源远离所述背板的方向上，其中，在对应所述灯板之间的间隙的区域，所述背板在远离灯板的方向上形成有凹槽，所述凹槽形成位于所述背板远离光源一侧的加强筋，所述凹槽内形成有散热结构；通过在背板对应灯板的间隙的区域形成凹槽，并在凹槽内形成散热结构，使得间隙处的散热增强，且散热结构可以增加背板的强度，同时凹槽形成的背板背部的加强筋可以进一步增加背板的强度，从而增加了灯板间隙对应区域的散热，同时，提高了背板的强度，缓解了现有背光模组存在灯板间隙处的温度较高，导致显示不均的技术问题。
在一种实施例中，如图4、图5所示，所述背板21与所述加强筋213一体成型，所述背板21冲压向外形成凸起和所述凹槽211，所述凸起形成所述加强筋213，即在形成背板的凹槽时，可以通过对背板进行冲压，使得背板向外凸起，从而形成了凹槽和凸起，该凸起可以起到加强筋的作用，从而使得凹槽对应的背板的结构向外形成加强筋，同时，由于该加强筋与凹槽分别位于背板远离光源的一侧和靠近光源的一侧，且均位于对应灯板之间的间隙的区域，使得在对灯板之间的间隙对应的区域进行散热的同时，也能对加强筋进行散热，同时，由于加强筋是通过背板冲压形成，无需另外设置加强筋，相对于现有技术，节约材料，降低成本和工艺难度。
在一种实施例中，如图3所示，所述散热结构212包括鳍片212，所述鳍片212阵列设置于所述凹槽211内，采用鳍片进行散热，同时，鳍片可以提高背板的强度。
需要说明的是，在图3中，散热结构212由鳍片212组成，因此散热结构与鳍片采用同一标号。
在一种实施例中，如图4所示，在对应灯板之间的间隙的区域形成凹槽211时，可以在横向排列的凹槽211和纵向排列的凹槽211的延伸交界处214不形成凹槽，即对交界处214的背板不进行处理，从而可以使得该处的强度较高，避免背板强度较低；但考虑到在凹槽内会设置鳍片增加背板的强度，也可以使得凹槽延伸到交界处，具体的可以使鳍片横向排列在交界处，也可以使鳍片纵向排列在交界处，从而提高背板的强度，增加灯板之间的间隙对应的区域的散热。
需要说明的是，横向和纵向为相互垂直的两个方向，例如图4中标注有211的纵向排列凹槽，相应的另一方向排列的凹槽为横向排列的凹槽。
在一种实施例中，如图3、图4所示，所述鳍片212与所述凹槽211的底部接触，所述鳍片212的两侧固定在所述凹槽211两侧，所述鳍片212的上端、与所述背板21与光源接触的一侧的间距范围（H2-H3）等于所述凹槽211的深度H2的五分之一至四分之一，在凹槽内设置鳍片时，为了增强背板的强度，可以将鳍片的两侧固定在凹槽的侧面上，具体的，可以直接将鳍片嵌在凹槽的侧面，从而避免鳍片出现移动或者弯折，同时，鳍片与凹槽的底部接触，可以进一步的固定鳍片，而鳍片的上端与背板靠近光源一侧的表面保持一定的间距，可以避免鳍片在超出凹槽时划伤灯板，避免对灯板产生损伤，同时，为了较好的提高背板的强度，鳍片的上端与背板靠近光源一侧的表面的间距也不能过大，因此设置鳍片的上端与背板靠近光源一侧的表面的间距范围为凹槽的五分之一至四分之一，在需要进一步提高背板的强度时，可以使得鳍片上端与背板靠近光源一侧的表面的间距更小。
在一种实施例中，所述凹槽包括横向排列的凹槽和纵向排列的凹槽，所述鳍片设置于所述纵向排列的凹槽内，具体的，针对灯板之间的间隙的散热较差的问题，可以在灯板的横向间隙设置凹槽，在凹槽内设置鳍片，从而提高灯板之间的间隙对应的区域的散热的同时，提高背板的强度，也可以在灯板的纵向间隙设置凹槽，在凹槽内设置鳍片，从而提高灯板之间的间隙对应的区域的散热的同时，提高背板的强度；还可以在灯板的横向间隙和纵向间隙设置横向排列的凹槽和纵向排列的凹槽，在横向排列的凹槽或者纵向排列的凹槽内设置鳍片，从而提高横向排列或者纵向排列的凹槽内的散热，并提高背板的强度。
在一种实施例中，如图4所示，所述鳍片212沿横向和纵向排列，在横向排列或者纵向排列的鳍片212中，相邻鳍片212之间的间距范围L1等于所述凹槽211的宽度L2的六分之一至二分之一，在设置鳍片的间距时，可以将鳍片设置的较为密集，从而提高对应灯板之间的间隙的区域的散热，同时，鳍片较为密集，可以提高背板的强度，具体的，相邻鳍片之间的间距为0.5毫米。
在一种实施例中，所述鳍片的厚度等于所述相邻鳍片之间的间距的十分之一至五分之一，对于鳍片的厚度，为了使得鳍片的数量较多，鳍片的设置密度较大，可以使得鳍片的厚度较低，同时，鳍片的厚度较低方便鳍片的设置，可以使得鳍片的厚度为相邻鳍片之间的间距的十分之一至五分之一，具体的，鳍片的厚度为0.1至0.2毫米。
在一种实施例中，所述鳍片的材料包括铝、铜、铝镁合金、铜锌合金中的一种，在设置鳍片的材料时，考虑到金属及其合金的导热性较好，可以采用金属及其合金制备鳍片，从而提高散热，具体的，可以采用铝及铝系合金、铜及铜系合金制备鳍片，例如采用铝镁合金，铝铜合金，铜锌合金，铜锡合金灯形成鳍片。
在一种实施例中，如图3所示，所述凹槽211的深度范围H2等于所述背板21厚度H1的二分之一至三分之二，在设置凹槽时，考虑到凹槽深度较大时，在设置有凹槽的区域和未设置凹槽的区域的交界处，可能会出现背板穿孔的问题，因此避免凹槽的深度过大，而为了提高对应灯板之间的间隙的区域的散热，凹槽的深度也不应该过小，因此设置凹槽的深度范围为背板的厚度的二分之一至三分之二，但本申请实施例不限于此，考虑到凹槽的深度会影响到对应灯板之间的间隙的区域的散热，在实际设置凹槽的深度时，可以根据散热需求设置凹槽的深度。
在一种实施例中，如图3所示，所述灯板为蓝光发光二极管灯板，所述灯板22上设有荧光层23，在光源为蓝光发光二极管时，可以在灯板上设置荧光层，使得灯板发出的光与激发荧光层产生的光混光发出白色的光。
在一种实施例中，可以使荧光层设置到虚线221处，也可使荧光层设置到虚线222处，可以使得空间较大，从而使得热量散发较快，也可以为了使荧光层围绕灯板设置，避免显示效果较差。
在一种实施例中，所述灯板为白光发光二极管灯板，在灯板为白光发光二极管时，可以直接将光学膜片设置在所述灯板上。
在一种实施例中，所述背光模组还包括金属层，金属层设置于背板远离光源的一侧，所述鳍片与所述金属层连接，通过将鳍片与金属层连接，使得热量能够更快的散发，从而加快灯板间隙处的散热。

背板21；
光源，设置于所述背板21上，所述光源包括拼接的多块灯板22，所述灯板22之间形成有间隙224；
