L幕数字沙盘

L幕数字沙盘是通过墙面或者地面上的大面积的投影或者LED播放系统来展示数字化信息，普通的数字沙盘影片和沙盘本身不是一体的，但是L幕数字沙盘能够让人们一边观看影片一边浏览沙盘。

The L-Screen digital sand table displays digital information through a large area projection or LED playing system on the wall or on the ground. Ordinary digital sand table movies are not integrated with the sand table itself, but the L-Screen digital sand table can let people browse the sand table while watching the movie.
