LED has the advantages of low voltage driving, environmental protection and energy conservation, high precision, large scattering angle, good consistency, ultra-low power, and ultra-long lifespan. Integrating the control circuit onto the LED makes the circuit simpler, smaller in size, and easier to install. Features: 1. High quality external control single line serial cascade constant current ICs are integrated into the LED. 2. The control circuit and chip are integrated into the SMD 2020 components to form a complete external control pixel point, with uniform and consistent effects. 3. A built-in data shaping circuit is installed, and any pixel point receives a signal and undergoes waveform shaping before outputting, ensuring that line waveform distortion does not accumulate. 4. A built-in power on reset and power off reset circuit is installed, Default power-on does not light up. 5. Gray scale adjustment circuit (256 grayscale adjustable). 6. Special processing of red light drive, more balanced color matching. 7. Single line data transmission, infinite cascading. 8. Shaping and forwarding reinforcement technology, transmission distance between two points exceeds 10M. 9. Data transmission frequency can reach 800Kbps. When the refresh rate is 30 frames/second, the number of cascading points is not less than 1024
