A Dynamic Sandbox and Its Display Control Method
Future Lab, Tsinghua University (Research Assistant), 2021
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, the driving device is connected with a second controller, the second controller is connected with two address signal lines corresponding to the gate and the pixel column, and is used to control the driving device to drive the selected pixel column to rise and fall 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.
