Description
本发明涉及LED显示屏技术领域,特别涉及一种LED显示模组及LED显示屏。
现有的LED显示屏底壳大部分通过打螺丝来起到连接与固定模组的作用,这样一来,若模组底壳的安装孔位与模组PCB板上焊接的铜柱出现轴向对位不正时(导致两者对位不正的原因主要有:1、由于模组底壳的安装孔位与模组PCB板本身存在一定公差,模组PCB板上的铜柱焊接过程中存在一定的角度倾斜,所有这些误差积累均可能会导致明显的对位不正;2、模组底壳在发生热胀冷缩的时候,模组底壳的安装孔位会随着模组底壳尺寸的变化而产生一定的位移,由于模组PCB板与模组底壳之间存在较大的热膨胀系数差值,模组底壳的安装孔位与模组PCB板上焊接的铜柱会产生一定的位移,从而导致明显的对位不正),会二者间会产生一定的应力,当这个应力超过临界值时,会导致强度相对较低的模组PCB板上的铜柱焊接部位失效,使得模组PCB板上的铜柱脱落,进而导致LED显示屏无法有效固定于箱体上,严重影响显示效果。
本发明要解决的技术问题是提供一种LED显示模组及LED显示屏,旨在解决现有LED显示模组容易出现因模组底壳上的安装孔位与模组PCB板上的铜柱对位不正而造成的铜柱脱落的技术问题。

可选地,所述安装孔位还包括若干环绕所述安装孔设置的第二弧形孔,且若干所述第二弧形孔沿同一圆周等间隔均匀分布;每一所述第二弧形孔对应的圆弧半径大于每一所述第一弧形孔对应的圆弧半径,以通过若干所述第一弧形孔及若干所述第二弧形孔共同形成所述环形镂空结构。
可选地,若干所述第一弧形孔与若干所述第二弧形孔沿所述安装孔的径向相错设置。
可选地,所述安装孔位包括四个所述第一弧形孔与四个所述第二弧形孔,以通过四个所述第一弧形孔及四个所述第二弧形孔共同形成所述环形镂空结构。
可选地,所述模组PCB板上固设有铜柱,所述铜柱远离所述模组PCB板的一端设有连接孔,连接件穿过所述安装孔后与所述铜柱的所述连接孔进行配合连接,使得所述模组PCB板与所述模组底壳紧固连接。
