Description

LED显示单元 技术领域
本申请属于LED显示屏技术领域，特别是涉及一种LED显示单元。
背景技术
随着科技的发展，LED显示屏具有亮度高、工作电压低、功耗小、大型化、寿命长、耐冲击和性能稳定等优点，被普遍应用于人们的生产生活中。LED显示屏的发展前景极为广阔，正朝着更高亮度、更高耐气候性、更高的发光密度、更高的发光均匀性，可靠性、全色化方向发展。LED显示屏广泛地应用在体育场馆、商业应用、银行、证券、邮政、码头、商场、车站、邮政、电讯、机关、监控、学校、餐厅、酒店、娱乐、等不同户外场所的广告宣传。
目前LED显示屏另一发展方向是大屏显示，例如户外广告或大型场景显示，有些用LED显示地砖或大屏游戏界面。大屏显示器通常由多块显示装置通过灯箱拼接，形成大型屏幕或超大屏幕。对于目前出现的LED大屏显示器而言，其整体的屏幕都是由若干LED箱体拼接而成的，在拼接的过程中需要辅助一些牵引以及吊装设备才能够完成拼接，另外在完成拼接之后施工人员还需要站在屏幕后方进行复杂的接线、接电以及线路连接工作，整体过程不但步骤复杂同时也极容易发生错误。
现在的拼接LED大屏显示器，通常注重于无缝拼接以及拼接安装的方便和稳定性，也就是说，现有的拼接LED大屏显示器基本都是平面式，极少有曲面大屏。现有的一些少数的曲面大屏也都是通过设置多个平面的LED灯箱的拼接角度，以形成曲面效果，这种曲面效果并不是真正意义上的曲面，LED灯箱还是采用传统的箱体结构形式，并没有根本上做到曲面化设计。

具体地，多个定位柱21分布为5排，限位弹片4设有两条，两条限位弹片4分别套设于第二排与第四排定位柱21上；能够更好的限制LED显示单元的极限弯曲度。
在一实施例中，如图2至图4所示，定位柱21为圆柱，且靠近灯板2的一端为前端212，另一端为后端213，前端212的直径大于后端213的直径；
限位弹片4上设有多个与后端213对应的第一通孔41，限位弹片4通过第一通孔41套设于后端213；将限位弹片4固定的更加牢靠。
在一实施例中，如图2至图4所示，第一通孔41的长度大于后端213的左 右长度；LED显示单元弯曲时，定位柱21沿第一通孔41滑动；当定位柱21移动至第一通孔41的最左端或最右端时，定位柱21不能继续向左或向右移动，此时LED显示单元的弯曲度为极限弯曲度，避免LED显示单元过度弯曲。
在一实施例中，如图2至图4所示，限位弹片4上设有第二通孔42，后体3的限位块32插设于第二通孔42内；弯曲LED显示单元时，限位块32沿第二通孔42滑动，且当限位块32抵接第二通孔42的沿定位柱21滑动方向上的端部时，定位柱21抵接第一通孔41的沿定位柱21滑动方向上的端部或定位柱21未抵接第一通孔41的沿定位柱21滑动方向上的端部；将LED显示单元极限弯曲时定位柱21受到的冲击力转移至到限位块32上，避免定位柱21产生脱落。
具体地，第一通孔41与第二通孔42在长度方向上的中心线位于同一直线，且第二通孔42靠近第一通孔41设置；便于加工与维修。
在一实施例中，如图1至图4所示，多个后体单元分为后体单元B31b、用于与LED显示屏的箱体固定连接的后体单元A31a与用于与LED显示屏的电源盒固定连接的后体单元C31c，后体单元A31a位于后体3的左右两端，后体单元C31c位于后体3的中间，后体单元B31b位于后体单元A31a与后体单元C31c之间；LED显示屏包括LED显示单元、箱体和电源盒，箱体与后体单元A31a固定连接，电源盒与后体单元C31c固定连接，避免了整个后体3与箱体紧密连接，减少LED显示单元的弯曲阻力。
在一实施例中，如图1及图2所示，后体单元C31c上设有第三通孔312，灯板2上相应的设有连接体22，连接体22插设于第三通孔312中；外接设备与连接体22电性连接，从而控制LED显示单元。
在一实施例中，如图2至图4所示，后体单元31的与另一后体单元31连接的一侧设为斜面，斜面自后体单元31的靠近灯板2的一端向后体单元31背离灯板2的一端倾斜；增大后体单元31间的间隙，有利于释放弯曲应力，避免后体3在弯曲过程中断裂。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
