优选地，面板5为钢化玻璃，耐磨性好。
在一实施例中，面板5粘接于前体4上，使得光线能直接穿过前体4和面板5到达外部，从而提高地砖屏的显示效果。
在一实施例中，请参阅图1，还包括盖板6，盖板6设于前体4与PCB板3之间，盖板6上设有多个容纳孔，灯珠嵌于容纳孔内；
盖板6上还设有多个供固定柱41穿过的通孔。盖板6用于保护灯珠，避免前体4压坏灯珠；盖板6还有限位灯珠的作用，避免灯珠在受到磕碰等意外时从PCB板3上掉落。
具体地，盖板6上还设有供支撑柱21穿过的通孔。
优选地，前体4、盖板6和后体2均由PC制造而成。
在一实施例中，请参阅图1，还包括固定件，后体2上设有安装孔，固定柱41穿过安装孔，固定件将固定柱41固定在后体2上，固定件位于PCB板3的背面，而灯珠发出的光是从PCB板3的正面射出的，因此固定件不会遮挡灯珠发出的光，从而提高了地砖屏的显示效果。
在一实施例中，请参阅图1及图2，固定柱41上设有固定孔，固定件能伸入固定孔内且与固定孔的内壁抵接，以便通过固定件与固定孔的内壁之间的摩擦力，用固定件将固定柱41固定在后体2上。
具体地，固定孔沿固定柱41的轴向延伸。
优选地，请参阅图2，固定件为螺钉，固定孔为螺纹孔，固定柱41通过螺钉固定在后体2上。
在一实施例中，请参阅图4，后体2上固设有定位柱103，箱体1上设有定位孔，定位柱103能伸入定位孔内，避免在使用地砖屏时后体2移动，并且在将后体2安装在箱体1上时，可先将定位柱103插入定位孔内，将后体2定位在箱体1上后再固定，结构简单，操作方便。
在一实施例中，请参阅图1，还包括后盖7、电源8和转接板9，后盖7固定于箱体1的背离后体2的一侧，电源8设于后盖7内，转接板9固定在后盖7内且位于电源8与箱体1之间，后盖7用于固定并保护电源8和转接板9，电源8用于向PCB板3提供电力，转接板9用于转换或传输信号。
在一实施例中，请参阅图1及图5，还包括第一密封圈10、第二密封圈101和第三密封圈102，第一密封圈10设于后体2与前体4之间，PCB板3嵌于第一密封圈10内，第一密封圈10能防止水从PCB板3的侧面进入，避免PCB板3短路；
第二密封圈101设于箱体1与后体2之间，第二密封圈101能防止水从箱体1与后体2之间进入，避免PCB板3短路；
第三密封圈102设于电源8与箱体1之间，第三密封圈102能防止水后盖7与箱体1之间进入到后盖7内，再从转接板9的侧面进入，避免PCB板3短路。
具体地，第一密封圈10设为多个，第二密封圈101设为多个，第三密封圈102设为一个。
优选地，第一密封圈10设为四个，第二密封圈101设为四个。
在一实施例中，请参阅图1，还包括用于固定箱体1的固定机构，固定机构设于箱体1的底部，以便在使用时将箱体1固定在地面上，避免箱体1移位而造成地砖屏与地砖屏之间的间隙过大，影响显示效果。
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。
