在一实施方式中，所述第一支撑板111上的多个所述第一固定孔161沿所述第一支撑板111的长度方向排布，所述第二支撑板121上的多个所述第一固定孔161沿所述第二支撑板121的长度方向排布，所述第一底板131的多个所述第二固定孔162沿所述第一底板131的长度方向排布，所述第二底板141的多个所述第二固定孔162沿所述第二底板141的长度方向排布，从而可以对第一底板131和第二底板141与第一支撑板111和第二支撑板121的连接位置进行调整，从而可以利用同一尺寸的部件组装成更多尺寸的背板10，以减少所需模组的数量。
具体的，所述第一支撑板111的宽度与所述第二支撑板121的宽度之和小于或等于所述第一弯折部112的内侧壁与所述第二弯折部122的内侧壁的间距，避免不同尺寸的背板10组装过程中第一支撑板111和第二支撑板121产生重叠妨碍背板10的组装。
需要说明的是，第一支撑板111的宽度尺寸与第二支撑板121的宽度尺寸可以根据实际情况进行选择，在保证所述第一支撑板111的宽度与所述第二支撑板121的宽度之和小于或等于所述第一弯折部112的内侧壁与所述第二弯折部122的内侧壁的间距的前提下，在不同尺寸的背板10中，第一支撑板111的宽度尺寸与第二支撑板121的宽度尺寸可以保持不变。
