Description

technical field

[0001] This application relates to the field of sand table models, especially an interactive international trade sand table model. Background technique

[0002] The interactive sand table refers to the industrial splicing of multiple industrial LCDs to form a large-scale display device, which combines the static model with the interaction of the multimedia touch screen. The user clicks on the touch screen with his finger to browse the special multimedia introduction and demonstration system, and vividly displays the model. For the visitors, the model is endowed with a more vivid connotation, which better interprets the concept of the design planner, and uses pictures, videos, animations and other information to explain.

[0003] Some interactive international trade sand table models that do not have LCD playback function need to use the corresponding model blocks to install the planned sand table line before displaying and interacting, and the operation is cu...
