 LED floor tile screen this product is widely used in stage display, commercial application, store decoration and other directions through innovative design. The emergence of  interactive LED floor  tile screen provides a more novel expression method for various performance creative design, which is a beneficial supplement to the current display equipment. With the increasingly prominent problem of product homogeneity in the  LED display  market, the emergence of interactive floor tile screen provides a reference idea for the innovative application of LED in China. The interactive floor tile screen has a good market prospect. 1. Development history of LED interactive floor tile screen Before the emergence of  interactive floor ​ tile screen, similar products in the market, luminous floor tiles, were also used in commercial decoration. The luminous floor tile can display patterns on the floor tile. This kind of luminous floor tile generally depends on the built-in single-chip microcompu

 3、 Design of LED display control circuit The LED control part is the core part that determines the display effect. The control circuit has a high-performance single-chip micro control chip. The controller sends the control signal and data to the LED driver chip through the internal control program. After receiving the signal, the LED driver chip generates the corresponding action, so as to realize the independent control of each red, green and blue LED light-emitting chip. 1. Outdoor LED floor drive system The function of LED driving part is to receive color data and drive the LED display screen to display according to the brightness value represented by the data. There are usually three # modes: constant current, constant voltage and constant current. The output current of the constant current drive circuit is constant, and the output DC voltage changes with the change of load resistance. The whole circuit is not afraid of load short circuit, but it is strictly prohibit
