The utility model relates to a three-dimensional pattern display device capable of being dynamically programmed. The three-dimensional pattern display device has the advantages that dynamical edition can be performed and the device is suitable for serving as a teaching aid for electronic technology and automation technology. The three-dimensional pattern display device capable of being dynamically programmed comprises a display control unit, an LED dimensional display array, a row driving unit, a column driving unit, an RAM, an EPROM, an E2ROM, a keystroke and a serial port; the display control unit is connected with the keystroke, the serial port forms a passage for receiving real-time programming commands, the RAM is used for storing data of patterns to be displayed, the EP ROM is used for the placement of a preset pattern base, and the E2 ROM is used for the placement of dynamically programming display pattern scripts; the LED dimensional display array is connected with the row driving array and the column driving unit, and the input end of the LED dimensional display array is connected with the output of the display control unit; the display control unit forms data of patterns to be displayed in the RAM according to the commands, and then scan and output the data to the row driving unit and the column driving unit, so as to control the patterns displayed by the LED dimensional display array.
