支架30设置于背光盒10之内，且该支架30设置于背光模组20的侧部，该支架30可以用于放置显示面板40。该支架30可以包括第一支撑部301和第二支撑部302，第一支撑部301插装在收容空间103中，且与背光盒10的底壁101相抵，用于支撑第二支撑部302。优选的，该支撑部301背光盒10的侧壁102平行设置。第二支撑部302设置于第一支撑部301远离背光盒10的底壁101的一侧，且朝显示面板20的方向延伸，可以用于放置显示面板40。需要说明的是，该第二支撑部302与第一支撑部301相互垂直设置。
在一些实施例中，可以分别在背光盒10的底壁101和支架30的第一支撑结构301上设置一卡扣结构，第一支撑结构301和底壁101通过卡扣结构卡接固定。还可以在第一支撑结构301和底壁101之间增加固定胶带，第一支撑结构301和底壁101通过固定胶带固定连接。
需要说明的是，由于增亮膜片203在对光线进行增强工作时会膨胀，为了防止增亮膜片203膨胀时膨胀过程中受到支架30的挤压导致损坏。因此，需要在背光模组20与支架30之间需要预留一缓冲空间。具体的，可以在背光模组20与背光盒10之间设置一间隙21作为缓冲空间。
显示面板40设置于支架30上。该显示面板40放置于第二支撑部302上。该显示面板40可以用于显示图像。在一些实施例中，该显示面板40可以通过一固定胶带70与支架30的第二支撑部302固定连接。
盖板50盖设显示面板40。盖板50可以用于保护该显示面板40。在一些实施例中，盖板50可以通过一光学胶80与显示面板40固定连接。在盖板50朝向背光盒10的表面和背光10的侧壁102朝向盖板50的表面之间具有一缝隙90。
该柔性电路板60穿过缝隙90与显示面板40电性连接。柔性电路板60可以用于为显示面板40提供显示电源。请参阅图3，显示面板40可以包括从下往上依次层叠的下偏光片401、薄膜晶体管402、液晶层403、彩膜基板404和上偏光片405。需要说明的是，该柔性电路板60与薄膜晶体管402与该显示面板40电性连接。
外界的水汽和灰尘等可以通过缝隙90进入显示模组1的内部，影响显示模组1的工作可靠性。
对此，为了避免外界的水汽和灰尘等可以通过缝隙90进入显示模组1的内部。在本申请实施例中，在柔性电路板60和盖板50朝向背光盒10的表面之间设置第一封装结构91，在柔性电路板60和背光盒10的侧壁102朝向盖板50的表面之间设置第二封装结构92，以密封缝隙90。防止外界的水汽和灰尘等通过该缝隙90进入显示模组1的内部。
该第一密封结构91靠近柔性电路板60的一侧和靠近盖板50朝向背光盒10的表面的一侧具有粘性，以使第一密封结构91可以粘附第一密封结构91靠近柔性电路板60的一侧和靠近盖板50朝向背光盒10的表面的一侧，不易脱落，增加第一密封结构91的稳定性。第二密封结构92靠近柔性电路板60的一侧和靠近背光盒10的侧壁102朝向盖板50的表面的一侧具有粘性，以使第二密封结构92可以粘附第二密封结构92靠近柔性电路板60的一侧和靠近背光盒10的侧壁102朝向盖板50的表面的一侧，不易脱落，增加第二密封结构92的稳定性。
在一些实施例中，为了增加第一密封结构91和第二密封结构92的密封性，可以使用具有伸缩性的材料制作第一密封结构91和第二密封结构92。比如，密封泡棉等。
由上述实施例可知，第一密封结构91设置于柔性电路板60和盖板50朝向背光盒10的表面之间。第二密封结构92设置于柔性电路板60和背光盒10的侧壁102朝向盖板50的表面之间。并且柔性电路板60与显示面板40的薄膜晶体管402电性连接。
对此，由于第一密封结构91和第二密封结构92具有可伸缩性，可以将第一密封结构91的厚度设置为大于或等于彩膜基板403的厚度、液晶层404、上偏光片405的厚度与光学胶80的厚度之和。将第二密封结构92的厚度设置为大于或等于固定胶带70的厚度、下偏光片401的厚度与薄膜晶体管402的厚度之和。
在具体实施过程中，可以通过施加外力使得第一密封结构91和第二密封结构92以压缩状态分别设置入柔性电路板60和盖板50朝向背光盒10的表面之间以及柔性电路板60和背光盒10的侧壁102朝向盖板50的表面之间。此时撤去外力，第一密封结构91和第二密封结构91伸张，第一密封结构91完全填充柔性电路板60和盖板50朝向背光盒10的表面之间的缝隙，第二密封结构92完全填充柔性电路板60和背光盒10的侧壁102朝向盖板50的表面之间的缝隙。
本方案通过在柔性电路板60和盖板50朝向背光盒10的表面之间设置第一封装结构91，在柔性电路板60和背光盒10的侧壁102朝向盖板50的表面之间设置第二封装结构92，可以完全密封盖缝隙90，隔绝了外界的水汽和灰尘等进入显示模组1的内部，从而提高了显示模组1的防尘、防水等能力，进而提高了显示模组1的可靠性。
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显示模组进行了详细介绍，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。
