需要说明的是，所述背光模组包括对应弯折位置的应力缓冲段10，以及邻接所述应力缓冲段10两端的非应力缓冲段20，更进一步地，在本申请实施例中，所述弯折位置包括所述框体101的相对两侧朝着背向所述胶体102一侧弯折以形成的第一弯折位置，即图1中所示（仅示出其中一侧），图1中示出有对应所述第一弯折位置的所述应力缓冲段10，另外，所述框体101包括多个侧壁，且所述弯折位置还包括所述多个侧壁中的相邻两者相连接以形成的第二弯折位置，即图3中所示，图3中示出有对应所述第二弯折位置的所述应力缓冲段10。
所述框体101顶部设置有用于贴合的胶体102、以及与所述胶体102错开设置的缓冲件104，其中，所述胶体102至少对应所述非应力缓冲段20设置于所述框体101顶部，并围绕所述框体101设置，所述缓冲件104至少对应所述应力缓冲段10设置于所述框体101顶部，所述缓冲件104包括单面胶、双面胶或泡棉胶材，以及所述缓冲件104的厚度介于0.02mm至1mm之间，需要说明的是，所述胶体102与所述缓冲件104相错开设置，但是所述胶体102与所述缓冲件104之间相互接触，并无间隔，可以起到防止所述背光模组发生漏光等不良现象的效果。
在本申请的一种实施例中，请参照图3所示，所述缓冲件104可对应设置于所述应力缓冲段10内，其设置长度可小于或等于所述应力缓冲段10的长度，当所述缓冲件104的长度等于所述应力缓冲段10的长度时，所述胶体102则对应设置于所述非应力缓冲段内，并与所述缓冲件104相接触，当所述缓冲件104的设置长度小于所述应力缓冲段10的长度时，则所述胶体102对应设置于所述非应力缓冲段20，并部分延伸至所述应力缓冲段10内，与所述缓冲件104相接触。
另外，在本实施例中，所述缓冲件104朝向所述框体101内部一侧形成有凸起，所述胶体102对应所述凸起的位置形成有槽口，且所述凸起与所述槽口相嵌合，所述凸起与所述槽口的卡合结构，避免了直线缝隙的产生，使得所述缓冲件104与所述框体101之间的缝隙为曲线或折线，进一步防止了所述缓冲件104与所述框体101之间发生漏光等不良现象。
在本申请的另一种实施例中，请参照图4所示，其与上述实施例的区别在于，所述缓冲件104对应设置于所述应力缓冲段10，并部分延伸至所述非应力缓冲段20，此时，所述胶体102对应设置于所述非应力缓冲段20内，并与所述缓冲件104相接触，且所述缓冲件104的设置长度增加，其对应力的缓冲作用也会增加，将进一步地增加背光模组对弯折应力的缓冲作用。
另外，在本实施例中，所述缓冲件104背向所述框体101内部一侧形成有凸起，所述胶体102对应所述凸起的位置形成有槽口，且所述凸起与所述槽口相嵌合，所述凸起与所述槽口的卡合结构，避免了直线缝隙的产生，使得所述缓冲件104与所述框体101之间的缝隙为曲线或折线，进一步防止了所述缓冲件104与所述框体101之间发生漏光等不良现象。
需要说明的是，所述胶体102与所述缓冲件104之间的缝隙形状不限于图示中所示的L型，还可以为V型或波浪形，以使得所述胶体102与所述缓冲件104之间的缝隙为曲线或折线，在此不作限定，更进一步地，在本申请实施例中，所述第一弯折位置下，所述胶体102与所述缓冲件104之间的缝隙亦可设置为曲线或折线，所述第二弯折位置下，所述胶体102与所述缓冲件104之间的缝隙亦可设置为直线。
综上所述，本申请实施例通过在框体的弯折位置设置缓冲件，并与胶体错开设置，使得背光模组在弯折位置具有对弯折应力的缓冲作用，进而使得背光模组在贴合过程中可以减轻弯折应力的影响，从而使得背光模组具有更好的机械和物理性能，防止贴合不良或失效的发生，另外，本申请实施例将胶体与缓冲件之间的接触缝隙设置为曲线或折线，进一步防止了背光模组发生漏光的现象，提高了显示效果和产品良率。
本申请实施例还提供一种显示装置，所述显示装置包括所述背光模组，以及通过所述胶体与所述背光模组相贴合的显示模组，所述显示装置可应用于曲面液晶显示器中，以减少所述显示装置中背光模组受到的弯折应力，提高了所述背光模组与所述显示模组贴合的稳定性和良率，提高了显示效果。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种背光模组及显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
