[0034] The display device adopts a three-layer structure of upper, middle and lower layers, with the upper layer purchasing modular replaceable scene training (experimental) modules, namely the function cards 3, the middle layer being the light-emitting device 1, and the bottom layer being the control circuit and I / O interface, so as to realize the completion of programming training teaching of training (experimental) modules with different functions in the same device;

[0035] The upper layer (front) has a wide variety of analog control object module function cards. The function cards have built-in encryption chips and adopt a low-power hidden design. The text and descriptions are printed with colored lines, with rich content and beautiful display.

[0036] The middle layer (front) has the light-emitting device 1, which is composed of a number of full-color light-emitting points 2, each of which can be switched to light up in full color.
