Intelligent reverse connection protection, power reverse connection will not damage the IC. The IC control circuit shares a power supply with the LED . The control circuit and the RGB chip are integrated in a 5050 packaged component to form a complete external control pixel. Built-in signal shaping circuit, any pixel receives the signal after waveform shaping and then output, to that the waveform distortion will not accumulate. Built-in power-on reset and power-down reset circuits. The three of each pixel can achieve 256 levels of brightness display, complete the full display of 16,777,216 colors, and the scanning frequency is not less than 400Hz/s. The serial cascade interface can receive and decode data through a signal . When the transmission distance between any two points is less than 5 , there is no need to any circuit. When the refresh rate is 30 frames per second, the number of cascades is not less than 1024 points. The data transmission speed can reach 800Kbps. The color of the light is highly and cost-effective. Main application areas LED full-color luminous character string light, LED full-color module, LED full-color flexible light bar, hard light bar, LED guardrail tube. LED , LED pixel screen, LED - screen, various electronic , electrical equipment marquee.
