具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明 中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明提供了一种显示模组，该显示模组包括中框1，以及粘贴在中框1内的导光板2，粘贴在导光板2上的反射片3；其中，中框1上设置有用于锁紧导光板2及反射片3的锁紧件5。
在上述实施例中，通过中框1固定导光板2，与现有技术中的显示模组相比，取消金属背板结构，使用导光板2补足强度，降低厚度15％～30％左右；且金属中框1与导光板2组装依靠胶水和卡钩双重固定，可靠性高，同时，降低了显示模组的厚度，有利于显示装置的薄型化发展。
为了方便理解本发明实施例提供的显示模组的结构以及原理，下面结合具体的实施例以及附图对其进行详细的说明。
继续参考图1，在本实施例提供的显示模组中，支撑装置靠中框1以及镶嵌在中框1内的导光板2来支撑整个显示模组的其他的结构。具体的如图1所示，该中框1的横截面为横置的T形结构，导光板2镶嵌在中框1内，且通过胶水与中框1的横梁粘接连接，从而保证了导光板2与中框1之间的固定连接。为了提高整个支撑结构的支撑强度，在一个具体的实施例方式中，该中框1采用具有较强支撑强度的材料制作的中框1，具体的，该中框1为铝合金材料制作的中框1，应当理解的是本实施例提供的中框1不仅限于上述举例的铝合金材料，还可以为钢材、铝、铁等其他具有良好支撑强度的材料制作的中框1。此外，该导光板2采用玻璃材料制作的导光板2，具有一定的支撑强度，使得在导光板2与中框1固定连接后可以形成一个稳定的支撑结构，从而无需使用背板等结构，且采用粘接连接的方式，减少了导光板2与中框1之间的连接部件，进一步的减少了显示模组的整体的厚度。
此外，在本实施例中，由于没有背板，因此，反射片3固定导光板2上背离中框1的一面，在具体的设置时，反射片3表面需涂布低折射率胶水和粘着剂后与导光板2贴合在一起，在粘合时采用的低折射率胶水的折射率需低于玻璃在空气中的折射率，从而避免对反射片3反射的光线造成影响。更 佳的，反射片3为涂布有低折射率材料的反射片3。更进一步的提高光线的传播效果。
如图2所示，本实施例提供的中框1为矩形框，矩形框包括第一边框11，与第一边框11成一体结构且位于第一边框11两侧的第二边框12及第三边框13，还包括与第二边框12和第三边框13通过连接件固定连接的第四边框14。具体的，如图2所示，该中框1的第一边框11、第二边框12及第三边框13为一体结构，可以通过折弯装置折弯形成该U形的结构，其中，第四边框14通过连接件与第三边框13和第四边框14连接。采用上述的分体结构，使得可以采用较小的模具即可实现对中框1的加工，提高了中框1的加工速度，且在第一边框11、第二边框12及第三边框13采用一体结构时，且中框1的横截面采用横置的T形结构，提高了中框1的支撑强度。为了更进一步的提高中框1的支撑强度，较佳的，该第四边框14与第二边框12及第三边框13连接的端部设置有搭接的结构，如图3所示，通过该搭接结构使得第二边框12、第三边框13及第四边框14部分重叠，在连接件连接时，保证了边框之间的连接强度，进而提高了中框1的支撑强度。
在本实施例中，为了提高整个显示模组的稳定性，较佳的，还包括锁紧件5，该锁紧件5用于将导光板2与中框1之间锁紧，避免在导光板2与中框1之间的粘合胶水失效后出现脱落的情况，较佳的，如图4所示，锁紧件5包括第一锁紧条51和第二锁紧条52，其中，第一锁紧条51和第二锁紧条52对称设置在中框1上相对的两个边框上。具体的如图4所示，第一锁紧件5和第二锁紧件5分别设置在第二边框12和第三边框13上靠近第一边框11的一端，且第一锁紧条51与第二锁紧条52通过连接件与中框1固定连接，且每个锁紧条具有卡紧导光板2及反射片3的折弯结构。提高了显示模组中的部件之间的稳定性。通过该折弯结构将导光板2及反射片3拖住，当锁紧条通过连接件与中框1连接时，该折弯结构与中框1的横梁部分加紧导光板2及反射片3，从而提高了导光板2及反射片3的稳定性，提高了部件之间的连接强度。
此外，为了提高整个显示模组的美观，较佳的，该显示模组还包括贴附在反射片3上的外观膜片4，且外观膜片4覆盖中框1朝向外观膜片4的一面。在具体设置时，反射片3背离导光板2的表面与中框1的表面齐平。从而使得显示模组具有良好的外观效果。
本发明实施例还提供了一种显示装置，该显示装置包括上述任一项的显示模组。
在上述实施例中，通过中框1固定导光板2。具体的，在本实施例提供的显示模组中，支撑装置靠中框1以及镶嵌在中框1内的导光板2来支撑整个显示模组的其他的结构。具体的如图1所示，该中框1的横截面为横置的T形结构，导光板2镶嵌在中框1内，且通过胶水与中框1的横梁粘接连接，从而保证了导光板2与中框1之间的固定连接。为了提高整个支撑结构的支撑强度，在一个具体的实施例方式中，该中框1采用具有较强支撑强度的材料制作的中框1，具体的，该中框1为铝合金材料制作的中框1，应当理解的是本实施例提供的中框1不仅限于上述举例的铝合金材料，还可以为钢材、铝、铁等其他具有良好支撑强度的材料制作的中框1。此外，该导光板2采用玻璃材料制作的导光板2，具有一定的支撑强度，使得在导光板2与中框1固定连接后可以形成一个稳定的支撑结构，从而无需使用背板等结构，且采用粘接连接的方式，减少了导光板2与中框1之间的连接部件，进一步的减少了显示模组的整体的厚度。
此外，为了提高整个显示模组的稳定性，较佳的，还包括锁紧件5，该锁紧件5用于将导光板2与中框1之间锁紧，避免在导光板2与中框1之间的粘合胶水失效后出现脱落的情况，较佳的，如图4所示，锁紧件5包括第一锁紧条51和第二锁紧条52，其中，第一锁紧条51和第二锁紧条52对称设置在中框1上相对的两个边框上。具体的如图4所示，第一锁紧件5和第二锁紧件5分别设置在第二边框12和第三边框13上靠近第一边框11的一端，且第一锁紧条51与第二锁紧条52通过连接件与中框1固定连接，且每个锁紧条具有卡紧导光板2及反射片3的折弯结构。提高了显示模组中的部件之间 的稳定性。通过该折弯结构将导光板2及反射片3拖住，当锁紧条通过连接件与中框1连接时，该折弯结构与中框1的横梁部分加紧导光板2及反射片3，从而提高了导光板2及反射片3的稳定性，提高了部件之间的连接强度。
通过上述描述可以看出，本实施例提供的显示装置中的显示模组与现有技术中的显示模组相比，取消金属背板结构，使用导光板2补足强度，降低厚度15％～30％左右；且金属中框1与导光板2组装依靠胶水和卡钩双重固定，可靠性高，同时，降低了显示模组的厚度，有利于显示装置的薄型化发展。
以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，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发明各实施例技术方案的精神和范围。
