Problems solved by technology
At present, most of the sand tables are still statically fixed, that is, the models made at one time according to the requirements cannot be adjusted and modified. After use, they are disassembled and discarded, which wastes manpower and material resources, and the use effect is poor; some sand tables use digital sand tables, but the input cost is high. Low popularity

The invention relates to the technical field of sand table display, and provides a dynamic physical sand table and a dynamic display control method thereof, comprising: a plurality of pixel modular units distributed in an array, and each pixel modular unit includes a plurality of pixel columns; The column is signal-connected with two signal gates through an address signal line, the two signal gates are connected with the first controller, and the two signal gates are connected with the first controller through a height signal line; each pixel column is connected There is a driving device, and the driving device is connected with a second controller. The second controller is connected with two address signal lines corresponding to the AND gate and the pixel column, and is used to control the driving device to drive the selected pixel column to move up and down according to the preset height signal. The present invention can use pixel modular units to assemble into a physical sand table of any size and high resolution, and any pixel column can be independently controlled to rise and fall to a specified physical height to achieve dynamic display.
Description
technical field [0001] The invention relates to the technical field of sand table display, in particular to a dynamic physical sand table and a dynamic display control method thereof. Background technique [0002] The sand table is a model piled up with sand, war games and other materials according to a certain proportional relationship according to topographic maps, aerial photographs or field topography, through which macroscopic things can be displayed intuitively. At present, most of the sand tables are mainly statically fixed, that is, the models made at one time according to the requirements cannot be adjusted and modified. After use, they are disassembled and discarded, which wastes manpower and material resources, and the use effect is poor; some sand tables use digital sand tables, but the investment cost is high. Low prevalence of use. SUMMARY OF THE INVENTION [0003] The invention provides a dynamic physical sand table and a dynamic display control method ther...
