Description

一种柔性LED显示屏 技术领域
本发明涉及一种LED显示屏，特别是涉及一种柔性LED显示屏。
背景技术
LED显示屏(LED display)是一种平板显示器，由一个个小的LED模块面板组成，用来显示文字、图像、视频、录像信号等各种信息的设备。LED显示屏以其发光亮度高、自动控制调节程度高以及节能环保的优点，广泛应用于户外及户内的光电显示领域。
现有技术的LED显示屏通常包括面罩、具有LED发光单元的PCB板和底壳，面罩设置在PCB板的前方，底壳设置在PCB板的后方，面罩、PCB板和底壳整体组合在一起形成整体的一块LED显示屏。这种显示屏整体呈直板状，不能进行折弯，所以现有技术的LED显示屏直接安装于弯曲的墙面上。当人们需要获得大尺寸弯曲的显示屏时，需要若干块小的LED显示屏拼接在一起才能够实现，但在两个LED显示屏连接处间隙较大，且不均匀，存在显示盲区，视觉效果差。
所以，急需开发一种可弯曲一定弧度的柔性LED显示屏，以满足人们的使用需求。
发明内容
本发明的目的在于避免现有技术中的不足之处而提供一种结构简单、安装方便，具有可弯曲一定弧度的一种柔性LED显示屏。
本发明的目的通过以下技术措施实现：
一种柔性LED显示屏，包括若干个底壳条、若干个与所述底壳条大小一致的面罩、设置于所述底壳条和所述面罩之间的具有LED发光单元的柔性PCB板，若干个所述底壳条依次排布成面状底壳组件，相邻所述底壳条之间设置有连接相邻所述底壳条的可使相邻所述底壳条向前或向后弯的柔性连接部，所述PCB板固定于所述底壳组件上，若干个所述面罩固定于所述PCB板上，所述面罩的 位置与所述底壳条的位置相对应。
优选地，上述柔性连接部包括设置于所述底壳条一侧的卡槽、设置于所述底壳条另一侧向外延伸的与所述卡槽相对应的卡扣，所述底壳条的所述卡扣活动卡于相邻所述底壳条的所述卡槽内。
优选地，上述卡槽由设置于所述底壳条一侧的两两相对设置的凸臂组成，所述卡扣包括杆件和设置于所述杆件端部的卡台，所述凸臂包括凸杆和设置于所述凸杆端部的挡块，所述卡槽的两个所述挡块设置于所述凸杆的内侧；所述杆件伸入所述卡槽内，所述卡台卡于所述卡槽内，所述卡槽内部的容积大于所述卡台的体积，所述卡台稍大于两相邻所述挡块的间隙，所述卡台卡于与所述挡块内。
优选地，上述底壳条设置有螺孔，所述PCB板设置有与所述螺孔位置相对应的第一通孔，所述面罩设置有与所述螺孔位置相对应的第二通孔，所述柔性LED显示屏还设置有与所述螺孔相配合的具有螺头的螺丝，所述螺丝依次穿入所述第二通孔和所述第一通孔后旋入所述螺孔，所述螺头卡所述第二通孔外。
优选地，上述面罩设置有与所述LED发光单元相对应的出光孔。
本发明与现有技术相比具有以下优点：本发明的柔性LED显示屏的若干个底壳条依次排布成面状底壳组件，底壳条之间用柔性连接部连接，该柔性连接部可以使相邻底壳条向前或向后弯，多个底壳条之间通过柔性连接部连接在一起。当所有的底壳条同时向前或向后折弯时，则整块的面状底壳组件可以向前或向后弯成一个较大弧度；当部分底壳条向前折弯，部分底壳条向后折弯，则整块的面状底壳组件可根据需要形成不同的波浪形状。柔性PCB板固定在底壳组件上，柔性PCB板可以跟随底壳组件的形状折弯成弧形或波浪形；若干个面罩固定在PCB板上，面罩的位置与底壳条的位置相对应，则面罩不需要折弯，多个面罩根据PCB板的形状固定在PCB板上，进而实现了整个LED显示屏向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状。
因为本发明一种柔性LED显示屏可向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状，所以，可以根据需要安装在弯曲的墙面上。本发明的柔性LED显示屏组装成一个整体，结构简单、安装方便，面罩之间的间隙较小，不存在显示盲区，显示均匀，视觉效果好。

具体实施方式
为使本发明更加容易理解，下面结合附图对本发明作进一步阐述，但附图中的实施例不构成对本发明的任何限制。
一种柔性LED显示屏，如图1至图9所示，包括若干个底壳条10、若干个与底壳条10大小一致的面罩30、设置于底壳条10和面罩30之间的具有LED发光单元41的柔性PCB板40，如图7所示，若干个底壳条10依次排布成面状底壳组件20，如图8和图9所示，相邻底壳条10之间设置有连接相邻底壳条10的可使相邻底壳条10向前或向后弯的柔性连接部11，PCB板40固定于底壳组件20上，若干个面罩30固定于PCB板40上，面罩30的位置与底壳条10的位置相对应。柔性PCB板40的LED发光单元41成整列分布。
本发明的柔性LED显示屏的若干个底壳条10依次排布成面状底壳组件20，底壳条10之间用柔性连接部11连接，该柔性连接部11可以使相邻底壳条10向前或向后弯，多个底壳条10之间通过柔性连接部11连接在一起。当所有的底壳条10同时向前或向后折弯时，则整块的面状底壳组件20可以向前或向后 弯成一个较大弧度；当部分底壳条10向前折弯，部分底壳条10向后折弯，则整块的面状底壳组件20可根据需要形成不同的波浪形状。柔性PCB板40固定在底壳组件20上，柔性PCB板40可以跟随底壳组件20的形状折弯成弧形或波浪形；若干个面罩30固定在PCB板40上，面罩30的位置与底壳条10的位置相对应，则面罩30不需要折弯，多个面罩30根据PCB板40的形状固定在PCB板40上，底壳条10之间的柔性连接部11对应的位置为面罩30之间的间隙，如图1所示，面罩30的间隙可以根据需要设计得比较小，进而实现了整个LED显示屏向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状。
因为本发明一种柔性LED显示屏可向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状，所以，可以根据需要安装在弯曲的墙面上。本发明的柔性LED显示屏组装成一个整体，结构简单、安装方便，面罩30之间的间隙较小，不存在显示盲区，显示均匀，视觉效果好。
较佳地，如图4至7所示，柔性连接部11包括设置于底壳条10一侧的卡槽50、设置于底壳条10另一侧向外延伸的与卡槽50相对应的卡扣60，底壳条10的卡扣60活动卡于相邻底壳条10的卡槽50内。即卡扣60卡入卡槽50内，具有一定的裕度值，卡扣60可以在卡槽50内向前转动或向后转动，进而带动相邻底壳条10向前或向后弯。当所有的底壳条10同时向前或向后折弯时，则整块的面状底壳组件20可以向前或向后弯成一个较大弧度；当部分底壳条10向前折弯，部分底壳条10向后折弯，则整块的面状底壳组件20可根据需要形成不同的波浪形状。进而实现了整个LED显示屏向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状。
较佳地，如图4至7所示，卡槽50由设置于底壳条10一侧的两两相对设置的凸臂51组成，卡扣60包括杆件61和设置于杆件61端部的卡台62，凸臂51包括凸杆52和设置于凸杆52端部的挡块53，卡槽50的两个挡块53设置于凸杆52的内侧；杆件61伸入卡槽50内，卡台62卡于卡槽50内，卡槽50内部的容积大于卡台62的体积，卡台62稍大于两相邻挡块53的间隙，卡台62卡于与挡块53内。
卡扣60的卡台62大小可稍大于卡槽50的挡块53之间的间隙，当卡扣60卡入卡槽50内时，卡槽50的两凸杆52在挡块53的推力作用，向两侧弹性弯了一下，卡扣60的卡入挡块53内后，凸杆52恢复原来的竖直位置，则此时杆 件61伸入卡槽50内，卡台62卡于与挡块53内了，卡台62不会从卡槽50的挡块53方向脱出，进而卡扣60不会从卡槽50的挡块53方向掉出。由于卡槽50内部的容积大于卡台62的体积，即卡台62在卡槽50内部有一定的裕度值，杆件61可以带动卡台62向前或向后转动，当杆件61转动到一定角度时，卡槽50底部和挡块53会抵挡住卡台62，进而确定了卡扣60在卡槽50内向前或向后弯的角度；另外由于整块的柔性PCB板40固定在底壳组件20上，卡台62也不会卡槽50的前后方向掉出，确保了柔性LED显示屏的底壳条10之间在折弯后不会脱节，确保了柔性LED显示屏结构的稳定性。
卡扣60可以在卡槽50内的一定的角度向前或向后转动，进而带动相邻底壳条10向前或向后弯。当所有的底壳条10同时向前或向后折弯时，则整块的面状底壳组件20可以向前或向后弯成一个较大弧度；当部分底壳条10向前折弯，部分底壳条10向后折弯，则整块的面状底壳组件20可根据需要形成不同的波浪形状。进而实现了整个LED显示屏向前或向后折弯成较大的弧度或根据需要折弯形成不同的波浪形状。
较佳地，如图1至图3所示，底壳条10设置有螺孔12，PCB板40设置有与螺孔12位置相对应的第一通孔42，面罩30设置有与螺孔12位置相对应的第二通孔31，柔性LED显示屏还设置有与螺孔12相配合的具有螺头71的螺丝70，螺丝70依次穿入第二通孔31和第一通孔42后旋入螺孔12，螺头71卡第二通孔31外。螺丝70依次穿入第二通孔31和第一通孔42后旋入螺孔12、螺头71卡第二通孔31外，即底壳组件20、PCB板40和面罩30通过螺丝70和螺孔12等配合固定在一起，结构简单，组装操作方便简单，连接牢固。
较佳地，如图3所示，面罩30设置有与LED发光单元41相对应的出光孔32。面罩30在LED发光单元41相对应的出光孔32，可以确保LED发光单元41发出的光较好地从面罩30射出，提高柔性LED显示屏的亮度。
以上所述是本发明的优选实施方式而已，当然不能以此来限定本发明之权利范围，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和变动，这些改进和变动也视为本发明的保护范围。
